Abstract
Nesocordulia McLachlan, 1882 is a poorly known dragonfly genus endemic to Madagascar and the Comoros. The genus is revised, and all twelve species are described, including six new ones: N. coloratissima sp. nov., N. evanida sp. nov., N. fossa sp. nov., N. ipsio sp. nov., N. lyricauda sp. nov., and N. odonator sp. nov. All are well-defined, with notably distinct male cerci, hamules, and colouration. While an identification key for males of all species is provided, this is based on single specimens for six of them. Females are known for only six species. While several radiations of damselfly genera had been recognised in the Malagasy Region already, Nesocordulia is the first to be uncovered in the suborder Anisoptera. Due to the scarcity of data, the exact drivers of their diversification remain unclear, however. While seven species are known from the humid and subhumid forest zone of eastern and north-western Madagascar, and only N. coloratissima and N. villiersi Legrand, 1984 appear confined to the drier west and to the Comoros respectively, the exact collection localities of three species remain unknown. Although the limited data suggest that most species are localised, the few species with more records appear to be fairly widespread. The species’ ecology is almost unknown, with more details provided on the habitat and behaviour of N. evanida only, and their conservation status is also largely unknown. Four species have not been recorded for over a century, however, while only N. coloratissima and N. evanida were confirmed to inhabit anthropogenically influenced landscapes.

Nesocordulia coloratissima Bernard, Daraż, Ravelomanana & Dijkstra sp. nov.
—Flame-tipped Knifetail 

Etymology. a declinable feminine latin adjective, formed from colorata- plus superlative suffix -issima, “the most colourful”. this is the most variegated species, with a striking spectrum of black, rusty brown, yellow, and white, as well as metallic with green, blue, golden, bronze, and violet reflections.

Diagnosis. This rather small Nesocordulia species is the most colourful and extensively yellow-marked in the genus. the black abdomen marked with yellow up to the base of d7, while the remainder is uniformly rufous, is unique, as are the yellow occipital triangle, yellow frons sides, broadly yellow centre of labrum, and the especially large yellow spot on the mesepimeron and metepisternum (sometimes narrowly divided into two large triangular spots but more frequently fused). the hamule and cerci are also unique (see figs 15–16 and 17–18, respectively), although the former is similar to that of N. evanida.

Nesocordulia evanida Bernard, Daraż & Dijkstra sp. nov.
—Little Knifetail  
Etymology. a declinable feminine latin adjective meaning “vanishing from sight”, as males are almost impossible to follow for the observer’s eyes due to the combination of their behaviour, disruptive camouflage, and the dappled light in their microhabitat.

Diagnosis. The smallest Nesocordulia species, separated from its probable closest relatives (N. coloratissima and N. malgassica) by the black rather than rufous s7–10 and its slightly, but distinctively distended cerci with black hair-like setae. differs from other black-tailed species by the shape of the cerci and hamule, as well as the thoracic markings with two triangular and three roundish yellow spots on each side.

Nesocordulia fossa Bernard, Daraż, Ravelomanana & Dijkstra sp. nov.
—Fossa Knifetail 

Etymology. the name, a noun in apposition, refers to madagascar’s largest carnivore, the similarly rufous, long-bodied and enigmatic Fossa (Cryptoprocta ferox Bennett, 1835).

Diagnosis. Comparatively large species, easily separated from all congeners except N. rubricauda by the reddish brown  body,  dark  brown  wing  bases,  and  denser  venation,  especially  between  the  cubital  and  anal veins. Aside from unique features, such as the shape of the cerci and hamule (see figs 15–16 and 17–18, respectively), yellow markings on the largely reddish brown thorax, and black apical smudges laterally on the reddish brown s3–6, differs from N. rubricauda by the yellow marking on the clypeus and the single cell rows subtended by Rspl.


Nesocordulia ipsio Bernard, Daraż & Dijkstra sp. nov.
—Dark Knifetail 
  Etymology. the name, a noun in apposition, refers to the CEPF project Insects and People in the Southern Indian Ocean (IPSIO), initiated by Brian fisher at the madagascar Biodiversity Center. K.-D.B. Dijkstra participated in the IPSIO expedition to marojejy national Park, but all specimens were collected by alan gardiner while he was seeking for butterflies.

Diagnosis. Medium-sized Nesocordulia species with a uniquely shaped hamule (see fig. 15) and the most extensive and contrasting dark markings on the labium and cerci in the genus. Only the presumably closely related N. odonator is similarly dark, sharing the limited thoracic pattern of small yellow spots, divided yellow lateroventral marking on S2, the laterally long but dorsally interrupted yellowish basal ring on S7, and dark epiproct. Nesocordulia ipsio differs from it, however, by a different hamule (see figs 15 and 16) and mostly blackish brown lateral lobes of labium, and is also significantly smaller.


Nesocordulia lyricauda Bernard, Daraż & Dijkstra sp. nov.
—Lyre-tipped Knifetail  

Etymology. a feminine noun derived from latin “cauda”, a tail, and “lyra”, an u-shaped instrument with two curvy branches, to describe the distinctive lyre-shaped cerci in dorsal view.

Diagnosis. the largest Nesocordulia species, separated by its unique long lyre-shaped cerci, large and uniquely shaped hamule (see fig. 15), and the basal yellow spots uniquely extending both dorsally and laterally on s7.  also has more Px in Fw (11–13 vs. 7–10) and Hw (13–14 vs. 7–11) than other black species.


Nesocordulia odonator Bernard, Daraż, Ravelomanana & Dijkstra sp. nov.
—Crabshear Knifetail  

Etymology. the name, a noun in apposition, like those for Syncordulia legator dijkstra et al., 2007, Syncordulia serendipator Dijkstra et al., 2007, and Syncordulia venator (Barnard, 1933), honours the explorers of odonata. this species and N. fossa were found on the same day of odonatours’ inaugural trip, whose participants sponsored the first introduction to malagasy odonata (dijkstra & Cohen 2021).

Diagnosis. Fairly large Nesocordulia species with unique hamule, in lateral view recalling a crab’s pincer (chelate appendage) with an almost spike-like dactyl, and unique labium with brown median lobe and mostly yellow lateral lobes. Only N. ipsio is similarly dark, sharing the limited thoracic yellow pattern of small spots, divided yellow lateroventral marking on S2, laterally long but discontinuous yellow ring on S7, and dark epiproct. N. ipsio has an even darker labium and cerci, however, and is also significantly smaller.

in DoNascimiento, Villa-Navarro, Albornoz-Garzón, Conde-Saldaña, Silva, Méndez-López, Roxo, Ortega-Lara et Oliveira, 2025. 

Abstract
A new genus of heptapterid catfish, Magdalenichthys gen. nov., largely ignored for the past two decades is herein described. Comprehensive examination of specimens in Colombian ichthyological collections and additional samplings in the Magdalena basin were the base for an integral analysis using morphological characters, DNA barcode delimitation, and molecular phylogenetic analyses to assess monophyly and relationships of the new genus, and to delimit and diagnose four new species, Magdalenichthys lundbergi sp. nov., Magdalenichthys mompox sp. nov., Magdalenichthys poira sp. nov., and Magdalenichthys yariguies sp. nov., endemic to the Magdalena basin. The new genus is phylogenetically diagnosed. Maximum likelihood, Bayesian inference, and coalescent-based analyses with ultraconserved elements (UCEs) data, place the new genus as sister to Phenacorhamdia, within a clade also containing Cetopsorhamdia and Pariolius, consistent with the finding of two apomorphic characters shared by the new genus and Phenacorhamdia. The biogeographic pattern of the new genus (restricted to the Magdalena basin) is also discussed.

Magdalenichthys DoNascimiento, Conde-Saldaña, Albornoz-Garzón & Villa-Navarro gen. nov.
 
Type species: Magdalenichthys lundbergi DoNascimiento, Villa-Navarro, Ortega-Lara, Albornoz-Garzón, Méndez-López & Conde-Saldaña sp. nov.

Diagnosis: A member of the tribe Heptapterini as defined by Silva et al. (2021). Magdalenichthys is distinguished from all other heptapterids by a single autapomorphy: posterolateral corner of lateral ethmoid with pointed posterior process, extending parallel and adjacent to the lateral margin of neurocranium, contacting the lateral margin of frontal, at level of anterior region of orbitosphenoid (vs. posterolateral region of lateral ethmoid devoid of any process, ending at posterior articulation with orbitosphenoid) (Fig. 1). Additionally, Magdalenichthys can be recognized from all members of Heptapterini (except Phenacorhamdia Dahl, 1961) by having a prognathous mouth (vs. terminal, subterminal, or ventral). Magdalenichthys differs from Phenacorhamdia by having an upper caudal-fin lobe longer than the lower lobe (vs. lower caudal-fin lobe longer) and hemal spines of vertebrae dorsal to insertion of anal fin simple (vs. bifid). Another character useful for its recognition among Heptapterini species from the Magdalena basin (except Imparfinis timana Ortega-Lara, Milani, DoNascimiento, Villa-Navarro & Maldonado-Ocampo, 2011) is the adipose-fin shape roughly rectangular [vs. rounded in Cetopsorhamdia boquillae Eigenmann, 1922 or triangular in Cetopsorhamdia molinae Miles, 1943, Cetopsorhamdia nasus, Imparfinis nemacheir (Eigenmann & Fisher, 1916), and Imparfinis usmai Ortega-Lara, Milani, DoNascimiento, Villa-Navarro & Maldonado-Ocampo, 2011], being further and easily recognized from I. timana by its shorter maxillary barbel, never surpassing the distal edge of the pectoral fin (vs. extending at least to the pelvic-fin base), and pelvic-fin origin at vertical though dorsal-fin origin or slightly posterior (vs. inserted at or slightly posterior to middle of dorsal-fin base).

Included species: Magdalenichthys lundbergi sp. nov., Magdalenichthys mompox sp. nov., Magdalenichthys poira sp. nov., Magdalenichthys yariguies sp. nov.

Etymology: In allusion to the Magdalena River basin, remarking on the restricted geographic distribution of this heptapterid genus to the Cauca and Magdalena rivers, which together form the main hydrographic basin of the trans-Andean region of Colombia, framed by the Western, Central, and Eastern cordilleras, the most salient feature of the Colombian geomorphology. Gender masculine.


Magdalenichthys lundbergi DoNascimiento, Villa-Navarro, Ortega-Lara, Albornoz-Garzón, Méndez-López & Conde-Saldaña sp. nov.

Etymology: The species name is dedicated to John G. Lundberg, in recognition of its seminal contributions to the systematics of pimelodoid and heptapterid catfishes, and for being an inspiring milestone in the first author’s career.

Magdalenichthys mompox DoNascimiento, Villa-Navarro, Albornoz-Garzón, Méndez-López & Conde-Saldaña sp. nov.

Etymology: The species name refers to the Cacique Mompoj of the Malibú tribe that once inhabited the region today corresponding to the municipality of Santa Cruz de Mompox, within the so-called Momposina Depression. This indigenous group was exterminated by the Spanish armies of Gerónimo Lebrón and Alonso Martín, during the Cesar massacre of 1540. Used as a noun in apposition.


Magdalenichthys poira Villa-Navarro, DoNascimiento, Albornoz-Garzón, Méndez-López & Conde-Saldaña sp. nov.

Etymology: The name poira is the most important indigenous mythological figure of the Tolima department and refers to the mischievous and libertine Mohán, who is a human-like being (when it appears in the form of a child or adolescent), with a face tanned by the sun, and penetrating and rougish eyes. The poira enchants and attracts young women, who often go to wash clothes on the banks of the river. Used as a noun in apposition.

Magdalenichthys yariguies DoNascimiento, Albornoz-Garzón, Méndez-López, Villa-Navarro & Conde-Saldaña sp. nov.

Etymology: The name yariguies honours the exterminated indigenous group that inhabited the río Cascajales drainage. Used as a noun in apposition.

[Ichthyology • 2025] Eviota vader • A New western Pacific Dwarfgoby (Gobiiformes: Gobiidae) from Papua New Guinea

 

Eviota vader
 Greenfield, Erdmann & Ichida, 2025


Abstract 
A new species of dwarfgoby, Eviota vader, is described from McLaren Fjord, Tufi, Papua New Guinea. The new species is characterized by a distinctive purplish-black coloration not found on any other species of dwarfgoby. In addition to the unusual color, it is diagnosed by the combination of a complete cephalic sensory-canal pore system, a dorsal/anal fin-formula of 8/7, some branched pectoral-fin rays, the fifth pelvic-fin ray present, and no dark occipital spots or any dark spots at the base of dorsal or caudal fins. The species is apparently endemic to the Tufi region of Papua New Guinea, a location known to have microendemic species.

in Mambrasar, Elliott et Cameron, 2024. 

Abstract

Two new species of Vireya Rhododendron, Rhododendron mulyaniae sp. nov. and R. engelbertii sp. nov. were discovered in Tambrauw, Papua, Indonesia. Rhododendron mulyaniae resembles R. angiense in that the scales under the leaf are dendroid, but differs in having elliptic to narrowly elliptic leaves, lacking hairs on petiole, having a tubular funnel shaped corolla. Rhododendron engelbertii resembles to R. carstensense in leaf shape but differs by having narrowly tapering leaf base, scales present on the petiole, and a corolla densely scaly on the outside. Detailed descriptions, illustrations and provisional conservation threat status of these newly described species are provided.

[Botany • 2025] Paraphlomis anisochila (Lamiaceae) • A New Species from Hunan, China

 

Paraphlomis anisochila  Y.P.Chen, A.Liu & F.Zhang, 

in Liu, H.-B. Chen, Zhang et Y.P. Chen. 2025.
 
Abstract
Paraphlomis anisochila, a new species from the subtropical evergreen broad-leaved forests of Hunan Province, southern China, is described and illustrated. Morphological comparisons indicate that P. anisochila is most similar to P. seticalyx, whereas molecular phylogenetic analyses based on a comprehensive sampling and two nuclear ribosomal DNA regions (ITS and ETS) place it as the sister species of P. yingdeensis. Paraphlomis anisochila is characterized by its unequal corolla lips, distinguishing it from all other Paraphlomis species. Additionally, it differs from P. seticalyx in lamina shape, petiole and calyx length, and from P. yingdeensis in plant indumentum, calyx tooth apex, and corolla color.

 Paraphlomis anisochila Y.P.Chen, A.Liu & F.Zhang, sp. nov.
 
Diagnosis. Paraphlomis anisochila is morphologically similar to P. seticalyx and P. yingdeensis, but differs from the former in having an obovate to subcircular (vs. broadly ovate) lamina, 0.5–2.5 cm (vs. 3.5–9 cm) long petioles, unequal (vs. subequal) corolla lips, and subcircular (vs. oblong) lateral lobes of the lower corolla lip, from the latter in having an abaxially sparsely strigose (vs. densely villous) lamina, an acuminate (vs. bristle-like-acuminate) apex of calyx tooth, and a white (vs. yellow) corolla with unequal (vs. subequal) lips.

Etymology. The specific epithet “anisochila” refers to the distinct corolla morphology of the new species, characterized by significantly unequal upper and lower lips, which differentiates it from other Paraphlomis species that typically possess subequal/equal corolla lips.

[Entomology • 2025] Cotesia ginginensis • A New Species of parasitoid wasp (Hymenoptera: Braconidae: Microgastrinae) from Queensland, Australia

 

Cotesia ginginensis Fagan-Jeffries & Davies,

in Fagan-Jeffries, Davies et Howe, 2025.

Cotesia Cameron, 1891 is the third largest genus of the braconid subfamily Microgastrinae, both in terms of described species  (>320  worldwide)  and  estimated  true  diversity  (1500+  species)  (Fernández-Triana et  al.  2020).  The  genus  is cosmopolitan  and  has  a  broad  host  range,  with  30  different  families  of lepidoptera  recorded  as  hosts,  and  with  many species acting as important biological control agents of pest lepidopterans (Fernández-Triana et al. 2020). The Australian Cotesia fauna was recently reviewed; there are 22 species currently known from the country, including several species introduced for biological control (Fagan-Jeffries et al. 2024; Fagan-Jeffries & Austin 2020).
 
Whilst there are likely to be many undescribed species of Cotesia in Australia and surrounding regions, we take the opportunity to add a single new species to the list of named biodiversity that was collected as part of a citizen science project, Insect Investigators. This citizen science project (insectinvestigators.com.au) ran in 2022 and involved 50 regional schools in Queensland, South Australia, and western Australia (Howe et al. 2025; insectinvestigators.com.au). Students and teachers ran Malaise traps on or near their school property, the samples were sorted and DNA barcoded, and a selection of specimens were sent to taxonomists to identify or include in current taxonomic projects. Two Queensland schools, gin gin State High School and Prospect Creek State School, each caught a single female specimen of a species in the genus Cotesia. Students and teachers at gin gin State High School collaborated with the authors to name the new species in 2023, and we here formally describe the species and raise the number of Cotesia from Australia to twenty-three.

Cotesia ginginensis Fagan-Jeffries & Davies, sp. nov.  

Diagnosis. Cotesia ginginensis can be separated from all other species of Cotesia currently described from Australia and Papua New guinea by the following combination of characters: mesosoma not dorsal-ventrally flattened (i.e., not as in Cotesia nonagriae (olliff, 1893)); fore wing r vein clearly longer than 2rS (r length >1.4 × length of 2rS); centre of the medial band of the mesoscutellar disc smooth; propodeum strongly sculptured with the medial carina clearly distinct for the whole length; T1 slightly broadening posteriorly but not strongly wedge-shaped (i.e., not as in C. ruficrus (Haliday, 1834)); T2 not strongly sculptured and T3 not densely setose (i.e., not as in C. rubecula (Marshall, 1885)).

[Invertebrate • 2025] Clavelina ossipandae • A New Species of Eusynstyela (Ascidiacea: Stolidobranchia) from Okinawa, Japan with Molecular Insight into Its Phylogenetic Position


Eusynstyela sesokoensis 
Hasegawa, 2025


Abstract
The colonial styelid genus Eusynstyela Michaelsen, 1904 comprises 12 species. Seven colonies of Eusynstyela were collected via SCUBA diving from three coastal sites in Okinawa, Japan, between 2018 and 2023. Morphological observations in this study identified these specimens as a new species, described here as Eusynstyela sesokoensis sp. nov. This species can be distinguished from its congeners by the following characteristics: i) ten oral tentacles, ii) twelve stomach plications, iii) absence of a stomach caecum, iv) no lobes on the anal rim, and v) two testes per gonad. Intraspecific variations were observed in zooid coloration and the number of longitudinal vessels on the pharyngeal folds. The molecular phylogenetic analysis based on a partial sequence of 18S rRNA and the mitochondrial cytochrome c oxidase subunit I genes indicates a possible sister relationship between the new species and E. latericius (Sluiter, 1904).

Significance: 
PFV 393 is the first radioisotopically dated (209.187 ± 0.083 Ma old) high-diversity continental vertebrate fossil assemblage to fill a 12-Ma fossil gap preceding the end-Triassic extinction. The taphonomy and depositional setting of this assemblage show that key members of post–Triassic Mesozoic vertebrate communities, including frogs, lepidosaur reptiles, pterosaurs, and turtles, coexisted with archaic lineages such as metoposaurid amphibians, trilophosaurid archosauromorphs, Vancleavea, doswelliids, phytosaurs, and aetosauriforms in the mesic fluvial environments of aridifying equatorial Pangaea approximately 7 Ma prior to the end-Triassic extinction. A member of this paleocommunity and one of the earliest few pterosaurs found outside of Europe, the newly described Eotephradactylus mcintireae gen. et sp. nov., reveals novel aspects of pterosaur mandibular evolution, ecology, and biogeography.

Abstract
Temporally constrained microvertebrate bone beds are powerful tools for understanding continent-scale biotic change. Such sites are rare globally in nonmarine settings during the 12 million years (Ma) preceding the end-Triassic extinction (ETE; ~201.5 Ma), obscuring patterns of faunal change across this interval. A vertebrate assemblage from Arizona, USA, provides unique insights into community composition and ecology prior to the ETE. PFV 393 is a macro- and microvertebrate bone bed preserved in a volcaniclastic fluvial channel-fill with a high-precision U-Pb zircon age of 209.187 ± 0.083 Ma. The fossil assemblage consists of three-dimensionally preserved, delicate, and small skeletal elements of known and new taxa that document a local paleocommunity including hybodontiformes, actinopterygians, actinistians, metoposaurids, salientians, synapsids, lepidosaurs, testudinatans, trilophosaurids, Vancleavea, doswelliids, Revueltosaurus, loricatans, phytosaurs, and pterosaurs. The new early-diverging pterosaur is one of the few Triassic pterosaurs found outside of Europe and the only one with a documented precise radioisotopic age. The testudinatan material shows the rapid dispersal of terrestrial stem-turtles across the Pangaean supercontinent in the Norian and refines temporal constraints on the origin of the turtle shell. The presence of vertebrate lineages endemic to the Triassic highlights their persistence in a mesic, fluvial paleocommunity through a prolonged phase of environmental change preceding the ETE. These lineages coexisted with frogs, lepidosaurs, turtles, and pterosaurs- all key elements of post–Triassic Mesozoic communities. The arrival of turtles and pterosaurs in west-central Pangaea therefore may have been driven by the northward drift of Laurentia from humid equatorial conditions into more arid subtropical latitudes.

life restoration of Eotephradactylus mcintireae catching a fish in the Chinle Formation environment.
An artist's reconstruction of the fossilized landscape, plants and animals found preserved in a remote bonebed in Petrified Forest National Park in Arizona. Researchers led by paleontologist Ben Kligman,, present the fossilized jawbone of a new pterosaur species and describe the sea gull-sized flying reptile along with hundreds of other fossils they unearthed from the site. These fossils, which date back to the late Triassic period around 209 million years ago, preserve a snapshot of a dynamic ecosystem where older groups of animals lived with evolutionary upstarts.
The newly described pterosaur Eotephradactylus mcintireae is seen eating an ancient ray-finned fish alongside an early species of turtle and an early frog species, with the skeleton of an armored crocodile relative lying on the ground and a palm-like plant growing in the background.

[Botany • 2025] A Synopsis of the Genus Jacquemontia (Convolvulaceae) in the Indo-Pacific with the Description of One New Species, Jacquemontia mohotaniensis


 Jacquemontia mohotaniensis Staples & Butaud,

in Staples, Butaud et Halford, 2025. 

Abstract 
Examination of specimens from the Marquesas Islands, French Polynesia, disclosed the presence of an undescribed species of Jacquemontia Choisy from the uninhabited island of Mohotani: the new species Jacquemontia mohotaniensis is described here and its conservation status is proposed as critically endangered. To place this novelty in context, a review of the native and naturalized Indo-Pacific taxa of Jacquemontia is provided; 14 names are accounted for and some taxonomic problems are highlighted for future study. New combinations are made for two Australian species, J. distigma (Benth.) Halford and J. flexuosa (Spreng.) Halford; a second step typification is provided for the latter name to stabilize the nomenclature.

KEYWORDS: biodiversity, Oceania, Marquesas, French Polynesia, Australia

 TYPE: French Polynesia. Society Islands: ...

 DIAGNOSIS: Jacquemontia mohotaniensis resembles most closely J. paniculata but differs from that species in the larger flowers, 1.5–1.8 cm long and up to 1.9 cm in diameter, the corolla subsalverform, 5-lobed, pure white, with exserted stamens and stigmas (Figure 1). The unequal sepals, the outer 2 larger and covering the inner, narrowly ovate-elliptic and 6–8 mm long 2–2.5 mm broad (Figure 2) serve to distinguish this new species from all other known Jacquemontia.

[Botany • 2025] Crawfurdia minuticalyx (Gentianaceae) • A New Species from Arunachal Pradesh, India


Crawfurdia minuticalyx R.Maity, Debta & S.S.Dash,

in Maity, Debta et Dash, 2025. 

Abstract
Crawfurdia minuticalyx, a new species of Crawfurdia (Gentianaceae) is described here from Arunachal Pradesh, situated in Eastern part of Indian Himalayan Region (IHR). This new species is unique in its very small calyx from its allied taxa. Morphologically, it shows close affinity towards C. speciosa Wall.; however, it can be differentiated by its much smaller leaves with entire margin; minute, non-splitted, calyx; relatively shorter corolla; stamens inserted below the middle of the corolla-tube, oblong anthers; short gynophore, and very short style. A detailed description and illustration are provided here along with comparative table of morphological characters, for easy identification.

Crawfurdia minuticalyx R.Maity, Debta & S.S.Dash, sp.nov. 

Diagnosis: Crawfurdia minuticalyx show close morphological affinity to C. speciosa Wall., but it can be differentiated by its much smaller habit; leaves with entire margin, and slightly flattened, 0.3–0.5 cm long petiole (vs crenulate leaf margin, and terete, 0.5–0.7 cm long petiole,); single bracteate flower (vs 2-bracteate flowers); 0.4–1.0 cm long pedicels (vs 1.0–6.0 cm long pedicels); 1–2 mm long, linear to narrow lanceolate bracts (vs 7–10 mm long, lanceolate bract); 0.2–0.5 cm long, ridged, campanulate, non-splitted calyx with 0.1–0.2 cm long, ovate to narrow ovate or lanceolate lobes (1.0–1.2 cm long, smooth, tubular calyx with split on one side, with 0.2–0.3 cm long, triangular lobes); 2.0–2.5 cm long, ...

Etymology: The specific epithet “minuticalyx” denotes very small or minute size of calyx which has been observed in the specimen during study and makes this species unique from other allied taxa
