Abstract

A new species, Microlicia almedae, is described and illustrated from the species-rich campo rupestre vegetation of Chapada Diamantina, Bahia, Brazil. The taxonomic novelty is morphologically related to M. giuliettiana and M. pulchra, which are also restricted to Chapada Diamantina. Microlicia almedae differs from the latter two species in leaf shape and size, hypanthium indumentum, calyx lobe shape and size, and petal size. In addition, M. almedae differs from M. giuliettiana by its uniformly magenta petals and from M. pulchra by its capsules with deciduous columellae. Variation in leaf shape among M. almedae, M. pulchra, and M. giuliettiana was quantified using elliptic Fourier analysis, which revealed near-complete separation among the three species.

DOI: doi.org/10.15553/c2026v811a1

 Abstract  

Taxonomy and molecular research in the genera of the subtribe Goodyerinae (Orchidaceae) from Madagascar and adjacent islands of the western Indian Ocean are discussed. The characteristics of Goodyera R.Br. and Platylepis A.Rich. are compared, their history is presented, and the respective species currently accepted for the region are detailed. A new species, Platylepis avaratraensis Hermans & Nusb., is described from the Sava region in northern Madagascar. It is most similar to P. humicola (Schltr.) Schltr. but differs by the wider leaves, shorter floral bracts, flower colour, narrower sepals and a lip with distinct calli. The distribution and ecology of the new species are discussed and its conservation status is provisionally assessed as “Endangered” following the IUCN Red List Categories and Criteria.

Platylepis avaratraensis Hermans & Nusb., sp. nov. 

Diagnosis — Platylepis avaratraensis is distinct from all other Madagascar species of the genus, and especially from P. humicola, by its long erect stem, narrowly elliptic to sub-ovate leaves (l/w ratio: 2.5–3/1), long inflorescence with a laxly flowered rachis in the apical third, floral bracts about as long as the pedicellate ovary, the rachis stem, ovary and exterior of the sepals and petals densely hirsute to villose with fine white hairs, the pale flowers with an orange-pink base to the lip, the obscurely 3-lobed lip with strongly involute margins, but without a spur, scattered thorn-like calli along the base, the curving epichile, ending in a fleshy, strongly recurved bilobed appendage, and the distinctly bifid rostellum.

Etymology — The specific epithet refers to the North (Avaratra in Malagasy) indicating its distribution in the northern part of Madagascar.

[Entomology • 2026] Scymnus tshunsii • The First termitophilous Ladybird Beetle (Coleoptera: Coccinellidae) from Microcerotermes Nests in Thailand

Termite nests host diverse symbiotic arthropods (termitophiles), many of which exhibit specialized morphological and behavioral adaptations to life within termite colonies. While numerous beetle families include well-known termitophiles, an association with termites has not yet been recorded in the family Coccinellidae (ladybird beetles). Here, we report the discovery of Scymnus (Pullus) tshunsii Seki, Liang & Maruyama, sp. n., based on adults and larvae collected from nests of Microcerotermes crassus Snyder, 1934, in Chiang Mai and Nakhon Ratchasima, Thailand, with additional adults captured at light traps. Although the adult morphology is typical for free-living Scymnini, the larva exhibits a highly unusual, soft-bodied, glabrous body form closely resembling termite workers - an apparent case of convergent evolution also seen in termitophilous rove beetles, scarabs, and phorid flies. The stark contrast between adult and larval morphology suggests stage-specific adaptations, with larvae more intimately integrated into the termite nest environment. Collecting adults at light traps indicates nocturnal dispersal, likely to locate new host colonies. This discovery represents the first confirmed termitophilous ladybird beetle and indicates that termite nests may support previously unrecognized ecological associations within Coccinellidae.

Scymnus (Pullus) tshunsii Seki, Liang & Maruyama sp. n. 

 

Diagnosis. Scymnus (Pullus) tshunsii sp. n. is similar in external coloration to many species of Scymnini (e.g., Sasaji, 1971; Chen et al., 2015a, b; Wang & Chen, 2022), but can be readily distinguished by the structure of the genitalia. This species is placed in the subgenus Pullus Mulsant, 1846 based on the combination of the following characters: antennae composed of 11 antennomeres, prosternal process with well-developed lateral carinae, abdominal postcoxal lines recurved and complete, and female genitalia with a distinct infundibulum (Chen et al., 2015a). Chen et al. (l.c.) divided the subgenus Scymnus (Pullus) from mainland China and Taiwan into S. hingstoni, S. subvillosus, S. impexus, S. perdere, and S. sodalis groups. The new species lacks a prominent dorsal keel on the penis guide of ...

Etymology. The species is named after Tshun-Sî, the son of Wei-Ren Liang, the second author. His name, meaning “sowing in spring,” reflects the hope for the flourishing of future studies on termitophily in Thailand following this groundbreaking discovery.

ABSTRACT

Notosuchia represents one of the most morphologically diverse groups of Mesozoic crocodyliforms and was particularly abundant in the Cretaceous of Gondwana. Among them, Peirosauridae comprises medium-sized terrestrial predators widely distributed across southern continents during the Late Cretaceous. Here we describe a new peirosaurid crocodyliform, Antusuchus rionegrinus gen. et sp. nov., from the Cenomanian Candeleros Formation of the Neuquén Basin (Río Negro Province, Argentina). The material, recovered from the La Buitrera Palaeontological Area, includes cranial and postcranial remains. Micro-computed tomography and anatomical comparisons reveal a unique combination of characters, including a short rostrum, an elongated palatal depression adjacent to the maxillary tooth row, a rod-shaped jugal bar, and a prominent sagittal crest. The dentition is ziphodont and includes a hypertrophied third maxillary tooth, consistent with predatory habits. Phylogenetic analyses recover Antusuchus rionegrinus as the earliest-branching member of Peirosauridae, sister to all remaining peirosaurids. This discovery provides new insights into the early evolution of peirosaurids and highlights the importance of the La Buitrera fauna for understanding mid-Cretaceous terrestrial ecosystems and the diversification of notosuchian crocodyliforms.

Abstract

Terror birds comprise an iconic group of apex predator birds from America, with a rich fossil record that is one of the longest among birds for a Neoaves family, ranging from the middle Eocene to the latest Pleistocene. Here, we report the discovery of a new genus and species of Phorusrhacidae, based on an incomplete tibiotarsus recovered from an Upper Pleistocene (25 326–25 733 cal yr BP) cave deposit in Bahia, northeastern Brazil, and previously interpreted as a New World vulture. The preserved morphology exhibits unique diagnostic features that support the recognition of a new species belonging to the small-size phorusrhacids, the Psilopterinae, a clade that probably had poor flying abilities. In addition to the systematic assignment, we discuss aspects of its palaeoecology (isotopic habitat and body mass estimate), providing new insights into the diversity and evolutionary history of the last known terror birds.

Abstract

Allium aralii Balos, Köse Sonay sp. nov. (Amaryllidaceae, sect. Codonoprasum) is described as a new species from southeastern Anatolia, Türkiye. The species is morphologically distinguished from its closest relatives—A. euphraticum, A. turcicum subsp. turcicum, A. turcicum subsp. fusciflorum, and A. yilandaghense—by a unique combination of characters: blackish outer bulb tunics, semi-cylindrical solid leaves exceeding the inflorescence, an extremely long persistent two-valved spathe (4.5–28.0 cm), a lax hemispherical inflorescence (3–4 cm diam., 10–70 flowers), a goblet-shaped perigon with dentate inner tepals, exserted bicolored stamens (white at base and apex, purple in the middle), a reticulate-foveate ovary, and verrucate seed ornamentation with undulate anticlinal walls. Seed micromorphology examined by scanning electron microscopy (SEM) further supports species delimitation. Molecular phylogenetic analyses based on nuclear ITS and chloroplast matK sequences place A. aralii within a well-supported clade containing A. turcicum and allied species, corresponding to the eastern Mediterranean lineage of sect. Codonoprasum. ITS genetic distances between A. aralii and its morphologically closest relatives range 0.0632, falling within the typical interspecific range for Allium. The species is known from a single locality in Bozova district (Şanlıurfa) with fewer than 100 mature individuals and is assessed as Critically Endangered (CR) according to IUCN criteria. This discovery highlights southeastern Anatolia as an underexplored center of Allium diversification and underscores the importance of integrative taxonomy for species delimitation within this taxonomically complex group.

Diagnosis: Allium aralii belongs to Allium sect. Codonoprasum and is morphologically distinguished from its closely related species—A. euphraticum, A. turcicum subsp. turcicum, and A. turcicum subsp. fusciflorum—by the following combination of characters: outer bulb tunics blackish (vs. brownish in A. euphraticum and A. turcicum subsp. turcicum, brownish-black in A. turcicum subsp. fusciflorum); bulbs 1.0–1.5 × 0.8–1.0 cm (vs. 1–2 cm in A. euphraticum, 1–2 cm in A. turcicum subsp. turcicum, 1–2 cm in A. turcicum subsp. fusciflorum); scape slender, 16–30 cm long (vs. 14–44 cm in A. euphraticum, 10–40 cm in A. turcicum subsp. turcicum and subsp. fusciflorum); leaves semi-cylindrical, solid, exceeding the inflorescence, 6.5–21.0 × 0.08–0.1 cm (vs. filiform, hollow, exceeding ...

Etymology: The species name ‘aralii’ was given in honor of the extraordinary academic achievements of the second author’s son, Aral Köse. Aral is an exceptional student who, after pursuing a dual degree in Electrical and Electronics Engineering and Mathematics at Boğaziçi University, has been awarded a full scholarship for a PhD program at the University of California, Santa Barbara (UCSB).

Turkish common name of the new species: Allium is called “Soğan” in Turkish. The author proposes “Kaplandağı soğanı” as a vernacular name for A. aralii according to the guidelines of Menemen et al. [2016].

Abstract

The present study describes one new species each of Georissa and Acmella from Northeast India. Georissa meghalayaensis sp. nov. and Acmella bensoni sp. nov. are described from Krem Puri, Meghalaya. In addition, Georissa sp. was newly recorded from a soil-leaf litter sample collected at the Sadu Chiru waterfall area in Manipur, and Georissa sarrita was newly recorded from Tuipui in Mizoram. All species were identified based on morphological features, with shell sculpture and suture being the primary distinguishing characters. Notably, all the species from Meghalaya were found inside caves, except for Georissa meghalayaensis (Krem Puri), which was found at the edge of the cave entrance on a wet, moss-covered rocky wall. Further studies are required to confirm the true cavernicolous nature of these microsnails.

[Botany • 2026] Goniothalamus metadoxus & Uvaria chrysoflora • Two New Species of Annonaceae from Papua New Guinea

Goniothalamus metadoxus Ezedin;
Uvaria chrysoflora Ezedin

in Ezedin. 2026.

DOI: doi.org/10.15553/c2026v811a6

 Abstract 

Two new species of Annonaceae bearing unique or unusual morphologies are described and illustrated from Papua New Guinea. Goniothalamus metadoxus Ezedin, from the Papuan Peninsula, exhibits an extraordinary reduction of the outer petals resulting in an inverted floral morphology where the inner petals appear larger and more prominent. It is further distinguished by its long pedicels, inner petals bearing a densely sericeous indument giving a silvery-white sheen, and long apiculate staminal connectives that are pinkish-lavender in color. Uvaria chrysoflora Ezedin, from the Sepik River basin, is unique in bearing greenish-yellow flowers, making it the first non-red flowered species of its genus from Papuasia. It most closely resembles the widespread U. concava Teijsm. & Binn. and can be further distinguished from the latter by its smaller leaves and larger flowers.

KEYWORDS: Annonaceae, Goniothalamus, New Guinea, new species, Uvaria

Goniothalamus metadoxus Ezedin
A, B: branch showing adaxial and abaxial laminas; C: cauliflorous inflorescence arising from excrescence on bole; D: close-up of a flower showing reflexed sepals and reduced outer petals; E: flower with one inner petal removed revealing inner chamber with pinkish-lavender colored stamens and light yellow carpels [Damas et al. SAJ1442] [Photos: S.A. James]

Goniothalamus metadoxus Ezedin, sp. nov. 

Diagnosis — Goniothalamus metadoxus resembles G. caloneurus Miq. in having similar leaf shape and siZe, oblong monocarps, and nearly subequal outer and inner petal siZes but differs in its habit being a small to medium tree up to 15 m tall (vs. shrub up to c. 4 m tall), laminas being chartaceous (vs. coriaceous), secondary veins not impressed above and not prominent below (vs. impressed above, prominent below), cauliflorous fasciculate inflorescences (vs. ramiflorous and solitary), inner petals being longer than the outer (vs. outer petals longer), and the petals silvery-white (vs. yellow-orange).

Etymology — From Greek meta, altered, and doxus, appearance; in reference to the inner petals being longer than the outer petals due to pronounced reduction of the latter.

Uvaria chrysoflora Ezedin
A: habit, twigs, mature and immature flowers; B: close-up of flower [Weiblen et al. GW2215] [Photos: G.D. Weiblen]

Uvaria chrysoflora Ezedin, sp. nov. 

Diagnosis — Uvaria chrysoflora resembles U. concava Teijsm. & Binn. in having subglabrous young stems and shortly pedunculate flowers with concave petals, but differs in its yellow-green petals (vs. maroon), petals not conspicuously incurved at apices (vs. strongly incurved), larger flowers measuring 35–50 mm across (vs. c. 18–30 mm), and smaller leaves measuring 10–12 × 5.5–6.5 cm (vs. c. 12–15 × 6–7 cm).

Etymology — From Greek chryso, golden, and Latin flora, flower; in reference to the yellowish-green flowers.

[Ichthyology • 2026] Brachygobius jennie • A New bumblebee goby (Gobiiformes: Oxudercidae) from Hengqin Island, Guangdong Province, China

Brachygobius jennie  

 Tian, Wu, Lan, Lavoué & Huang, 2026. 

 DOI: doi.org/10.3897/zse.102.184142

Abstract

A new species of bumblebee goby, Brachygobius jennie sp. nov. (Teleostei, Oxudercidae), is described based on 31 specimens collected from the Hengqin Island, Guangdong Province, China. This new species is distinguished from all other valid species of Brachygobius by its extreme small size (SL < 9 mm) and distinctive number, position, size and shape of its black bars. It possesses four complete (forming ring) or nearly complete post-cephalic, relatively narrow bars, two of which are located posterior to the base of the anal fin. The first bar behind the head extends pigmentation to the first dorsal fin but does not reach the midventral line. The second bar, chevron-shaped and located below the second dorsal fin, extends pigmentation onto that fin and ventrally reaches the midventral line and the anal fin. Cytochrome oxidase subunit I-based analyses, including six out of the eight valid species of Brachygobius, show Brachygobius jennie sp. nov. to be more than 10% genetically divergent from other species, supporting the morphological diagnosis and confirming its distinct taxonomic status. With a maximum size of less than 9 mm SL (based on observations of 106 specimens), the new species is not only the smallest species of Brachygobius, but also one of the smallest known gobioid fishes.

Abstract

Salween River basin’s karst ecosystems in southeastern Myanmar remain largely unexplored and are likely to harbour a high terrestrial snail diversity that are often associated with high levels of snail endemism. Here, an outstanding group of new karst-associated terrestrial snails, Burmochlamys gen. nov., are discovered. A study of the comparative morphological and anatomical data reveals that the reproductive tract and radula of this new genus are closely related to the helicarionid genus Sophina Benson, 1859 but shell morphology (shape, size, and sculpture) and mantle extensions are distinct from the latter genus. Burmochlamys gen. nov. now consists of four known nominal species, B. cassidula comb. nov., B. cauisa comb. nov., B. perpaula comb. nov., and B. poongee comb. nov., and five new species; B. albida sp. nov., B. fasciola sp. nov., B. moulmeinica sp. nov., B. versicolor sp. nov., and B. whitteni sp. nov. The highlight is that the members of the new genus show site-specific endemism, being restricted to karstic habitat islands of the Salween River basin. In addition, the discovery supports that the unique and complex structure of Salween River basin’s karst ecosystems are habitats in which the terrestrial malacofauna have speciated and become endemic.

Genus Burmochlamys Pholyotha & Panha, gen. nov.

 

Type species: Burmochlamys fasciola sp. nov., by original designation.

Etymology: The name combines Burmo in reference to Burma, the historical name of Myanmar, and the Greek word chlamys meaning mantle or cloak in reference to land snail with well-developed mantle extensions. Therefore, the generic name means the Burmese land snail with the well-developed mantle extensions. The gender of the new generic name is feminine.

Diagnosis: Shell subglobose to globose, small size, little high spire, and sculptured with spiral furrows and undulating radial lines. Snail with five well-developed mantle extensions; caudal horn raised. Genitalia with penial retractor muscle attached at tip of epiphallic caecum; gametolytic organ with rather short to moderate cylindrical duct and bulbous sac; well-developed dart apparatus; flagellum absent. Radula with large monocuspid central tooth and attached by two smaller teeth; laterals and marginals undifferentiated, large monocuspid, and at base of each tooth on outer side attached by a smaller tooth.

Abstract

Two new taxa of Platycleidini have been discovered in southern Albania, with one of them extending its range to the Greek border. In this paper, we analyse their morphological features, the characteristics of their acoustic signals, and phylogenetic relationships. These taxa clearly belong to the cluster of species comprising the four genera Montana, Amedegnatiana, Parnassiana, and Metrioptera s. str. The results of this study suggest their placement within the genus Montana, and we describe two new species: Montana tomorri sp. nov. and Montana dani sp. nov. Our findings highlight the urgent need for a reassessment of the tribe Platycleidini using integrative approaches that incorporate molecular and bioacoustic data, in order to better understand monophyletic groups and evaluate the consistency of current generic classifications.
