Abstract

Telipogon is a highly diverse genus in the Andes, yet it remains incompletely documented in northern Peru. Telipogon vasqueznunezii is morphologically similar to T. hystrix but differs in the oblong-ligulate lip, the two small lobes at the lip base, the absence of a protrusion on the lip, and the tuft of acicular setae on the columnar appendix. A detailed description, illustrations, a distribution map, and a conservation assessment are provided here.

Diagnosis: Telipogon vasqueznunezii is most similar to Telipogon hystrix (Dodson) N.H.Williams & Dressler but is distinguished by the larger flowers (9–11 × 8–13 mm vs. 5 × 5 mm), the obovate to sub-oblong petals (vs. narrowly ovate), the oblong-ligulate lip (vs. elliptical to oblong), the sub-auriculate lip base with a pair of small lobes (vs. the sagittate base with two long lobes), the absence of a protrusion on the lip (vs. a hump-like protrusion on the lower half), and one tuft of acicular setae on the columnar appendix (vs. one tuft of setae with a stellate apex on the columnar appendix).

Eponymy: The species is named after Dr Leopoldo Pompeyo Vásquez Núñez, a Peruvian botanist and professor at Universidad Nacional Pedro Ruiz Gallo. Professor Vásquez has dedicated his life to better understanding the plant diversity of northern Peru with a focus on potentially useful plants.

[Botany • 2026] Primula xingyiensis (Primulaceae) • A New Species from Guizhou, China

Primula xingyiensis  Z.K.Wu & C.Y.Deng,

in Shi, Deng, Lang, Liu et Wu, 2026.

DOI: doi.org/10.3897/phytokeys.276.195710

Abstract

Primula xingyiensis Z.K.Wu & C.Y.Deng, a new species of Primulaceae from Guizhou, China, is described and illustrated. Morphological evidence places P. xingyiensis within Primula sect. Carolinella, a section characterised by plants completely efarinose but bearing pubescent or glandular hairs; leaf base cordate to rounded, rarely broadly cuneate, with distinct petioles; calyx campanulate or narrowly campanulate, longer than its diameter, split to 1/3–1/2 of its length; and capsule oblong, dehiscing nearly calyptrate at maturity. The new species is distinguished by its gracile habit, shortened stem, small leaves with long villous hairs on both surfaces, long-styled homostylous flowers, and a corolla that is 7–8 times as long as the calyx. Information on the distribution, morphological comparisons with closely related species, and the conservation status of the new species is also provided, along with a key to the known species of Primula sect. Carolinella.

ABSTRACT

Lacustrine sediments of the Lower Cretaceous (lower Aptian) Xiagou Formation exposed near the village of Changma in the Changma Basin of northwestern Gansu Province, China have yielded more than 100 avian partial skeletons, many of which also preserve remnants of soft tissues such as feathers and skin. Collectively, these fossils characterize a rich avifauna dominated by the crownward ornithuromorph Gansus yumenensis Hou and Liu, 1984. Despite this wealth of Early Cretaceous bird material, no skeletal remains of other dinosaurs have been described from Changma to date. Here we report the first non-avian dinosaur body fossil from the Xiagou Formation of the Changma Basin. Consisting of an articulated left pectoral girdle and forelimb lacking the carpus and manus, the specimen pertains to a new dromaeosaurid theropod taxon, Jian changmaensis, gen. et sp. nov. Phylogenetic analysis recovers Jian within Microraptorinae, expanding the definitive fossil record of this clade to include northwestern China. The new Changma microraptorine constitutes an additional similarity between the theropod faunas of the Xiagou Formation of the Changma Basin and penecontemporaneous strata of the Jehol Group of northeastern China. In particular, the Changma theropod assemblage closely resembles that of the Sihedang locality of the Jehol Group in that both include representatives of Microraptorinae and are overwhelmingly dominated by single ornithuromorph taxa that phylogenetic analyses have repeatedly resolved as close relatives. This raises the possibility that the two sites were deposited under comparable paleoenvironmental settings that are otherwise poorly represented at known Jehol localities.

Diagnosis.—Medium-sized (intermediate in skeletal dimensions between adult specimens of Microraptor zhaoianus and Sinornithosaurus millenii Xu et al., 1999; see Table 2) microraptorine dromaeosaurid theropod characterized by the following three autapomorphies: (1) a coracoid that is proportionally longer relative to the humerus than in any other microraptorine (~36% humerus length; the next closest individuals are the immature Microraptor IVPP V31612, with a value of ~35%, and IVPP V12811, the holotype of Sinornithosaurus, with a value of 33%) (Table 2); (2) humeral distal condyles developed on the cranial surface of this bone (Figs. 2B–C, 3E; a local autapomorphy within Microraptorinae, shared with nonmicroraptorine theropods such as the therizinosaur Erlikosaurus andrewsi Barsbold and Perle, 1980, and Aves); and (3) a well-developed foramen on the ventral aspect of ...

Etymology.—The genus name is for the Jiān (鹣), a one winged bird in Chinese mythology, in reference to the bird-like, possibly volant nature of this microraptorine taxon and the skeletal composition of its holotype (an isolated partial pectoral girdle and forelimb). The specific name is for Changma (昌马), the locality where the holotype was discovered.

DOI: doi.org/10.11646/zootaxa.5807.1.2

 

Abstract

Kongobatha is one of the most commonly encountered of all Australian mantis genera, and yet despite this, very little is known about the taxonomy or biology of the genus. Described to include a single Australian species, K. diademata, the only subsequent work on the genus has been the description of a second species from New Guinea, K. papua. We here describe three additional species, K. spinosistyla Connors sp. nov., K. serpens Connors sp. nov., and K. rufilinea Connors sp. nov., and redescribe K. diademata and K. papua in detail, the latter of which is recorded from Australia for the first time. We also describe for the first time the unusual, heavily spinose styli of male Kongobatha. These are apparently unique among Mantodea as a whole, but their function remains unknown.

Abstract

Two new species of Calotes lizards, Calotes thailandensis sp. nov. and C. maehongsonensis sp. nov., are diagnosed and described from Thailand. These new species are most closely related to C. irawadi and C. wangi, which are members of the C. irawadi complex, supported by phylogenetic analysis of mitochondrial DNA data (ND2 and COI genes) coupled with morphometric and osteological data. Calotes thailandensis sp. nov. and C. maehongsonensis sp. nov. are distinguished from true C. irawadi by having a wider PelvW, but a smaller head size in adult males. In particular, adult males of C. thailandensis sp. nov. obviously differ from both C. irawadi and C. wangi by having a longer supratympanic spine, whereas C. maehongsonensis sp. nov. has a distinctly longer hindlimb than that of C. irawadi and C. wangi. As a result, two new species increase the list of known Calotes species in Thailand to four species; C. thailandensis sp. nov., C. maehongsonensis sp. nov., C. emma and C. goetzi.

Meiolaniformes are a group of chelonians including the famous horned-turtles Niolamia argentina (Patagonia) and Meiolania platyceps (Australia). In South America, the Late Cretaceous meiolaniforms are represented by two named taxa: Patagoniaemys gasparinae coming from Campanian–Maastrichtian beds of the La Colonia Formation, Chubut province, and Trapalcochelys sulcata from the Campanian–Maastrichtian beds of the Allen Formation, Río Negro Province. The aim of the present contribution is to describe a new meiolaniform chelonian coming from the Upper Cretaceous (Maastrichtian) Los Alamitos Formation, at Río Negro Province, Argentina. The material is represented by a partial basicranium, incomplete carapace and fragmentary postcranial bones (MPMIK 1839/P/33) belonging to a new species Patagoniaemys aeschyli. To this new species we refer all the material previously referred as indeterminate meiolaniid, meiolaniform and cf. Niolamia sp., coming from the same site and locality, and described by different authors since the 1980s. This new species differs from the type species P. gasparinae, particularly by the presence of longitudinal ridges in the nuchal bone. We also include brief comments about meiolaniform palaeobiogeography and the impact of K/Pg extinction event in Patagonian chelonians.

Key words: Testudinata, Meiolaniformes, Los Alamitos Formation, Maastrichtian, Cretaceous, Patagonia, Argentina.

Diagnosis.—Large chelonian (maximum anterior carapace width about 60 cm, maximum inferred carapace length 80 cm). Referable to meiolaniforms by several features, namely the presence of small pits and grooves ornamenting carapace bones, anteriorly curved grooves among marginal scutes, opisthocoelous caudal vertebrae, and carapace-plastron connection through ligaments (Gaffney 1996; Hirayama et al. 2000; Sterli and de la Fuente 2013; Sterli et al. 2013). It is referred to Patagoniaemys by having a basioccipital with well-developed basal tubera with a concave surface between them, posteriorly flat occipital condyle, a shallowly notched anterior carapace margin, presence of a thickened bump on ...

Etymology: In reference to Aeschylus (525–455 BC), an ancient Greek writer often described as the father of tragedy.

DOI: doi.org/10.24823/ejb.2026.2089

Abstract

Gentiana macneilliana (Gentianaceae), a new species from North Sikkim, in the Eastern Himalayan region of India, is described, illustrated and discussed. It is morphologically similar to Gentiana lacinulata T.N.Ho of Gentiana sect. Chondrophyllae Bunge but differs markedly in having acute and usually mucronate leaf apex, ovate corolla lobes with acuminate apex, much longer plicae (1.5–2.6 mm), which are more than half as long as corolla lobes, and longer pedicel (up to 8 mm). This new species also resembles Gentiana muscicola C.Marquand (Gentiana sect. Chondrophyllae) but can easily be differentiated by its unique corolla lobe, shorter petiole, narrowly based leaf lamina, longer pedicel and shorter style. The affinity of the new species with Gentiana grata Harry Sm., a member of the same section, is also highlighted. A taxonomic description, images and illustrations of the new taxon are provided, along with a discussion of closely related taxa.

Gentiana macneilliana A.K.Halder & D.Maity, sp. nov.

Gentiana macneilliana is morphologically most similar to Gentiana lacinulata but differs from that species by its short petiole, 0.5–1.5 mm long (vs up to 3 mm); acute and usually mucronate leaf apex (vs obtuse leaf apex); narrowly revolute leaf margin (vs flat leaf margin); longer pedicel, up to 8 mm long (vs up to 3 mm long); ovate corolla lobes with acuminate apex (vs suborbicular with obtuse-rounded or rounded apex); much longer plicae, 1.5–2.6 mm long (vs 0.7–1 mm); and plicae more than 1/2 as long as corolla lobes (vs less than 1/3 as long as corolla lobes). It also resembles Gentiana muscicola but can be differentiated from that species by its unique ovate, acuminate corolla lobes with erose margin and distinctly contracted base (vs ovate–lanceolate or ovate–triangular, obtuse or subacute lobes with entire margin and widened base); short petiole, 0.5–1.5 mm long (vs up to 2.5 mm); narrowed leaf bases (vs rounded to cordate leaf bases); long pedicel, up to 8 mm (vs up to 3.1 mm); and short style, 1.5–1.9 mm (vs 3–4 mm). 

Etymology. The specific epithet ‘macneilliana’ is given in honour of Dr John McNeill, Royal Botanic Garden Edinburgh (E), the legendary taxonomist and nomenclature specialist, who has given immense support with the nomenclature of Indian Gentiana.

Abstract

Based on the molecular phylogenetic analyses of six plastid DNA regions (matK and rbcL exons; trnL intron; atpB-rbcL, psbA-trnH and trnL-trnF intergenic spacers) and including 57 samples of Pseuduvaria, as well as thorough morphological studies, Pseuduvaria sirindhorniana (Annonaceae, Miliuseae) is described and illustrated here as a new species from Narathiwat, southern Thailand. The new species belongs to a major clade that also includes P. fragrans, P. gardneri, P. glossopetala, P. kwangtungensis, P. multiovulata and P. phuyensis. Pseuduvaria sirindhorniana is morphologically most similar to P. glossopetala, but differs by having basally connate (vs. free) sepals, larger petals, elliptic-ovate (vs. obovate) outer petals, inner petals that are only connivent at the apex (vs. connivent from the base to ± the midpoint and at the apex), with openings formed from the base (vs. openings formed from ± the midpoint). Pseuduvaria kwangtungensis turns out to be a putative sister of the new species, but the two are morphologically dissimilar in several traits, such as leaf base, inner petal appearance and glands on the inner side of the inner petals.

 Pseuduvaria sirindhorniana differs from the morphologically most similar species, P. glossopetala, by having basally connate (vs. free) sepals, larger petals, elliptic-ovate (vs. obovate) outer petals, inner petals that are only connivent at the apex (vs. connivent at the apex and from the base to ± the midpoint), with openings formed from the base (vs. openings formed from ± the midpoint). 

Etymology — The specific epithet honours H.R.H. Princess Maha Chakri Sirindhorn of Thailand, who has continuously supported the study of plant taxonomy in Thailand and worldwide, on the auspicious occasion of her 72nd (6th cycle) birthday anniversary (2 April 2027). She has also been instrumental in establishing the Plant Genetic Conservation Project under the Royal Initiative (RSPG), which aims to train personnel and develop plant genetic resources for the conservation of plant diversity, with benefits extending to farmers and related sectors of the country.

Vernacular name — Ruchi Sirin (รุจิสิริน).

Abstract

Background and aims – Psittacanthus is the largest genus of neotropical mistletoes within Loranthaceae, comprising approximately 110 species. With 37 species recorded to date, Colombia stands as the most diverse country for this group of aerial hemiparasites. Despite this richness, a comprehensive national or regional taxonomic revision of these mistletoes is currently lacking. This study aims to update the knowledge of Colombian Psittacanthus diversity by describing a new species and reporting new records for the country.

Material and methods – This study is based on an extensive literature review and the examination of herbarium material of Psittacanthus. We examined herbarium specimens using both physical collections and high-resolution digital images. Morphological analyses were conducted using dried and rehydrated samples, following the standardized specialized terminology for neotropical mistletoes. Taxonomic descriptions and diagnoses were developed to establish and test taxonomic hypotheses, ensuring a rigorous comparison between focal taxa and previously described species.

Key results – A new species for the Colombian Andes is described, and four new records for the Amazonian and Andean–Amazonian Piedmont of Colombia are reported. Psittacanthus job-kuijtii sp. nov. is described and illustrated herein; this species inhabits the moist lowland forests of the Colombian inter-Andean valleys, which are areas containing exceptional biodiversity. Furthermore, P. amazonicus, P. lamprophyllus, P. pilanthus, and P. zonatus are recorded for the first time for Colombia. The description of this new species and the additional records increase the known diversity of Colombian Psittacanthus to 41 taxa and a total of 111 species for the genus.

Diagnosis. Psittacanthus job-kuijtii differs from the remaining species in the genus by the combination of the following characters: percurrent shoots; leaf blades ovate to broadly lanceolate, base truncate to rounded, margins revolute and adaxially extending toward the petiole, forming a V-shaped projection, apex attenuate to acuminate; inflorescences usually double triads, rarely triple triads, or a monad with two triads (all variations were observed in the holotype); flowers 4–5 cm long in pre-anthesis; petals red to orange in the proximal and medial portions and yellow distally with a deltoid, fleshy basal ligule bearing minute papillae, 1.8–2 mm long; stamens dimorphic, staminal hairs absent. Psittacanthus job-kuijtii is similar to P. peronopetalus, but differs from it by having usually double (rarely triple) triads (vs umbels of four triads), and flowers opening at anthesis with petals recurved for about 2 cm (vs flowers opening only at the apex, with petals recurved for no more than 2 mm).

Abstract

A new species of the genus Stygioides Bruand, 1853 (Lepidoptera: Cossidae) is described from central Turkey. Stygioides hecate Japaridze & Junnilainen sp. nov. is based on material collected in the Sultan Daðlarý Mountains (Konya Province). The new species is characterised by its distinct wing coloration in females. Adults are diurnal, as in other members of the genus, and were collected by daytime netting. DNA barcode data (COI) are provided and compared with available sequences in the Barcode of Life Data Systems (BOLD Systems), supporting the distinctiveness of the new taxon. The discovery of this species increases the number of Stygioides species to 10 and those from Turkey to three, thus contributing to a better understanding of the diversity and distribution of the genus in the Palaearctic realm.

Stygioides hecate Japaridze & Junnilainen sp. nov. 

Diagnosis: Males of S. hecate Japaridze & Junnilainen sp. nov. differ from S. nupponenorum by the presence of a distinct white tip of the male abdomen and white scales on the antennae, the absence of brown piliform scales on the abdomen, a narrower apex of the valvae, and a shorter saccus (Figs 1A–1B, 2 C; cf. Lingenhöle et al. 2016: fig. 6; Yakovlev 2011: fig. 35). Females are readily distinguished from all congeners by the presence of golden-yellow scales on the antennae, head, thorax and wings (Figs 1C–1D; cf. Lingenhöle et al. 2017: figs 1–3, 9; Japaridze et al. 2025b: fig. 22).

Etymology: The species name is derived from Hecate, the ancient Greek goddess associated with the night and commonly depicted carrying yellow or golden torches. This name alludes to the coloration of the holotype female, which is predominantly black with yellow-golden scales on the wings, thorax, head, and antennae.
