Abstract

Vincetoxicum phucanhense (Apocynaceae, Asclepiadoideae), a new species from Vietnam, is described, illustrated, and compared with three morphologically similar species: Vincetoxicum flexuosum (R.Br.) Kuntze, V. harmandii (Costantin) Meve & Liede, and V. tengii (Tsiang) Meve & Liede. V. phucanhense differs from V. flexuosum in having shorter pedicels, very sparsely hairy sepal margins (vs. glabrous), a larger corolla, broadly elliptic pollinia (vs. globose), longer fruits, and longer seeds. It also differs from V. harmandii in having shorter petioles, smaller leaf blades, glabrous adaxial leaf surfaces (vs. hairy), and a larger corolla. In comparison with V. tengii, V. phucanhense can be distinguished by its larger corolla, corolla coloration (yellow, pink, or red vs. greenish), and broadly elliptic pollinia (vs. globose). A key to the 14 species of Vincetoxicum recorded in Vietnam is provided.

Diagnosis. Vincetoxicum phucanhense differs from V. flexuosum by its shorter pedicels (4.0–7.6 mm vs. 14.0–16.0 mm), sparsely hairy sepal margins, larger corolla (7.2–9.6 mm diam, vs. 4.0–6.0 mm), broadly elliptic pollinia, longer fruits (109–123 mm vs. 40–80 mm), and longer seeds (9.2–9.5 mm vs. 6.0–8.0 mm). It is distinguished from V. harmandii by having shorter petioles (3–8 mm vs. 10–20 mm), smaller leaves (9–42 × 4–18 mm vs. 45–75 × 25–45 mm), glabrous adaxial leaf surfaces, and larger corolla (7.2–9.6 mm diam. vs. 4–5 mm). From V. tengii, it differs by its larger corolla (7.2–9.6 mm diam. vs. 5–7 mm) and differently colored corolla, as well as the broadly elliptic rather than globose pollinia.

Abstract

The genus Niceforonia currently includes 17 species of small, terrestrial, direct-developing frogs distributed from Colombia to northern Peru. In Colombia, 11 species of Niceforonia have been reported, with five of these restricted to high Andean ecosystems, including Páramos. Field surveys conducted between 2017 and 2023, in the Páramo ecosystems of the Puracé National Park and its buffer zone, in southwestern Colombia, revealed a previously unidentified species of Niceforonia. Through an integration of phylogenetic, ecological, bioacoustic, and morphological analyses, we identified unique traits that support the recognition of this population as a new species of Niceforonia, restricted to Páramo and Subpáramo habitats over 3300 m in the Colombian Massif. The new species is sister to Niceforonia brunnea, which occurs 195 kilometers further south in the Department of Nariño of southwestern Colombia and northern Ecuador. With the discovery of this new species, Colombia now hosts 12 species of Niceforonia, six of which inhabit Páramo ecosystems. Our study expands the taxonomic knowledge of the genus and underscores the importance of further exploration in high-Andean ecosystems of southwestern Colombia, where biodiversity remains underexplored.

[Paleontology • 2026] Yujingia glutenotunica • Cambrian Fossils illuminate the ambulacrarian common ancestor

 

Yujingia glutenotunica 

He, Mussini, Han, Reich, Ou, Cheng & Shu, 2026 

胶膜玉净虫  |  DOI: doi.org/10.1016/j.cub.2026.08.053

Highlights: 

• A new early Cambrian ambulacrarian, Yujingia, preserves soft parts and tentacles

• Yujingia possesses pinnate appendages with filter-feeding grooves

• Phylogenetic analyses place Yujingia near the common ancestor of extant Ambulacraria

• The fossils suggest living ambulacrarians evolved from tentaculate suspension feeders

Summary

The origins of ambulacrarians, which comprise the morphologically disparate echinoderms (sea stars and their relatives) and the worm-like hemichordates, are poorly constrained, obscuring the assembly of their exceptionally disparate body plans. We describe Yujingia glutenotunica, an ambulacrarian from the early Cambrian Chengjiang biota (518 Ma). Yujingia combines a simple cylindrical body plan with a crown of specialized appendages, including pinnate arms bearing filter-feeding grooves and alternating side-branches. Phylogenetic analyses recover Yujingia within a grade of tentaculate fossils immediately basal to the last common ancestor of all modern ambulacrarians. These results suggest that ambulacrarians evolved from semi-sessile organisms with complex suspension-feeding adaptations, otherwise only found in crown-group echinoderms and tentaculate hemichordates (pterobranchs). Yujingia fills a key gap in the early deuterostome fossil record, thus challenging the conventional worm-like, pharyngeal filter-feeder models for the ambulacrarian last common ancestor and supporting unexpectedly deep origins for the echinoderm and pterobranch body plans.

Etymology: The generic name Yujingia refers to the Dharma Vessel held by Guanyin, one of the Four Great Bodhisattvas of Chinese Buddhism, in reference to the fossil’s overall shape. The specific name glutenotunica is derived from the Latin words gluten and tunica, which refers to the optically light body preserved around the visceral mass of the fossil. ...

ABSTRACT

The Mazon Creek fossil assemblage has provided the earliest fossil records of several important early tetrapod lineages, including the oldest dissorophoid temnospondyl, Amphibamus grandiceps. Recent systematic efforts have unveiled exceptional diversity of recumbirostran tetrapods at Mazon Creek; however, similar attention has not been paid to the numerous temnospondyl fossils from the site. Here, we provide an anatomical and systematic revision to a uniquely preserved amphibamiform from Mazon Creek, FMNH PR 558, that was previously reported to have the earliest body fossil evidence of lissamphibian-like toe pads in temnospondyls. Restudy of this fossil, with particular attention devoted to the dorsal and lateral skull and the axial skeleton has revealed distinct differences from coeval and other Permo-Carboniferous amphibamiforms, allowing for the designation of the new taxon Jeanerpeton mazonensis, gen. et sp. nov. Based on preliminary observations of varying presacral vertebral counts among Mazon Creek amphibamiform fossils there is more diversity of this group from the Moscovian amongst known material than previously recognized.

Abstract

Fish-scale geckos (Geckolepis), endemic to Madagascar and the Comoro Islands, are nocturnal, arboreal lizards with large, imbricate scales that can be shed and regenerated in their entirety, most likely as an antipredator mechanism. Their species-level taxonomy has remained partly unresolved because morphology alone has proven insufficient to reliably assign genetic lineages to scientific names. Here, we use a museomics approach to extract and shotgun-sequence DNA from twelve liquid-preserved historical and mostly name-bearing type specimens of six historical nomina in the genus, and assemble sequences of the mitochondrial genes for 12S rRNA, 16S rRNA, and nd4 for ten of these specimens. Despite relatively low coverage, the assembled sequences robustly placed all these type specimens in a phylogenetic tree with 113 ingroup samples collected across Madagascar. Our results demonstrate the efficiency of this approach to recover mitochondrial evidence for taxonomic purposes, but also show its failure to recover reads matching single-copy nuclear genes. We discuss the promise of a renewed focus on nuclear ribosomal genes as complementary nuclear-encoded DNA barcodes for vertebrates, as we found 18S rRNA sequences to be well-represented among the reads of the historical specimens studied here. Based on evidence from the mitochondrial tree, two nuclear-encoded genes (C-MOS, RAG-1), and morphology, we resurrect G. typica var. modesta Methuen & Hewitt, 1913 as a full species, G. modesta, from north-western Madagascar, confirm the current use of the name G. maculata Peters, 1880 for specimens from northern and eastern Madagascar, of G. polylepis Boettger, 1893 for specimens from western and north-western Madagascar, and of G. typica Grandidier, 1867 for specimens from southern and south-western Madagascar. We also recognize G. typica var. anomala Mocquard, 1902 as a subspecies, G. typica anomala, and confirm G. petiti Angel, 1942 to be a synonym of this subspecies. We also describe two new species, G. bekira sp. nov. and G. spania sp. nov. from northern Madagascar. The new classification provides a robust baseline to identify the remaining taxonomic issues in the genus and tackle them, preferably using genomic approaches which are also promising to better understand the molecular mechanisms of scarless wound healing and skin regeneration in these geckos.

Diagnosis. Assigned to the genus Geckolepis based on molecular phylogenetic relationships and body covered with large, imbricated scales. Based on morphological data of Lemme et al. (2013), characterized by snout–vent length <54 mm, 25–28 scales around midbody, 33–43 ventral scale rows, condition A or B of mental scale, eight supralabials, and usually a dark stripe from eye to ear opening. The new species differs from G. humbloti, G. maculata, G. megalepis and G. modesta by a smaller body size (SVL in these species reaching up to 65–75 mm), from G. megalepis and G. modesta furthermore by more scales around midbody (25–28 vs. 17–25), and from G. megalepis also by more ventral scale rows (33–43 vs. 27–32); from G. typica by a different condition of mental scale (A or B vs. D); from G. polylepis by having fewer ventral scale rows (33–43 vs. 48–55) and more scales around midbody (25–28 vs. 35–38). The new species can be differentiated from all other species and lineages in the genus complex by numerous diagnostic nucleotide positions in the mitochondrial genome. MolD identified for the nd4 fragment a robust diagnostic nucleotide combination of an “A” at site 904, a “C” at site 975, and a “T” at site 1002 (positions relative to the full nd4 gene of Geckolepis).

Etymology. The species name is derived from the Malagasy words be (= big) and kira (= scale), referring to the large imbricated scales that distinguish this and other species of Geckolepis from other Malagasy geckos. The species epithet is an invariable noun in apposition to the generic name.

Geckolepis spania sp. nov. 

Diagnosis. Assigned to the genus Geckolepis based on molecular phylogenetic relationships and body covered with large, imbricated scales. Characterized by small body size (but holotype is probably not adult), 26 scales around midbody, 34 ventral scale rows, condition A of mental scale, 7–8 supralabials, and presence of a dark stripe from eye to ear opening. The new species differs from G. modesta and G. megalepis by more scales around midbody (26 vs. 17–25), and from G. megalepis also by more ventral scale rows (34 vs. 27–32); from G. maculata (A+B) by more scales around midbody (26 vs. 22–25); from G. maculata (C) by fewer ventral scale rows (34 vs. 36–42); from G. humbloti by a larger number of supralabials compared to most specimens of that species (7–8 vs. 5–7); from G. typica by a different condition of mental scale (A vs. D); from G. polylepis by having fewer ventral scale rows (34 vs. 48–55) and fewer scales around midbody (26 vs. 35–38); reliable morphological differentiation from G. bekira is not possible at present. The new species can be differentiated from all other species and lineages in the genus complex by numerous diagnostic nucleotide positions in the mitochondrial genome. MolD identified for the nd4 fragment a robust diagnostic nucleotide combination of an “A” at site 876, and a “C” at site 943 (positions relative to the full nd4 gene of Geckolepis).

Etymology. The species name is a latinized adjective derived from Greek σπάνιος (spánios = rare), used in the feminine gender in agreement with the genus name. It refers to the rare occurrence of this species, which is known from a single collected specimen, despite numerous herpetological explorations of its type locality, Ankarana National Park.

Abstract

A new species of Pagodapalaina from southern Thailand is described. Pagodapalaina euphrosyne Sutcharit, sp. nov. is characterised by a sinistral, elongate-fusiform shell with an open-coiled teleoconch, well-developed radial ribs restricted to the penultimate and last whorls, and the presence of the parietalis and columellaris. Unlike all other congeners, the detached teleoconch subsequently resumes regular coiling, with the last whorl becoming tightly reattached to the preceding whorl. This previously undocumented developmental pattern raises fundamental questions about current understanding of the developmental constraints governing shell coiling in terrestrial caenogastropods.

Family Diplommatinidae Pfeiffer, 1856

Genus Pagodapalaina Chen, 2025

Pagodapalaina Chen in Chen et al. 2025: 390, 391.

Type species: Diplommatina acme Laidlaw, 1949, by original designation.

Remark: The genus is characterised by a sinistrally coiled, elongate-fusiform shell with tightly to loosely coiled whorls and a shell surface bearing low ridges to prominent and trough-like radial ribs. The internal lamellar system comprises a well-developed columellaris, a parietalis varying from small to well developed, a vertical palatalis that may be absent, and a constriction ranging from weak to strong.

The genus currently comprises 18 recognised species (Chen et al. 2025, MolluscaBase 2026, this study). Of these, three species are known from Sumatra, Indonesia, and nine species, including the new species described herein, are recorded from Thailand. The northern distributional limit of the genus is currently considered not to extend beyond the Isthmus of Kra (Fig. 1A).

Neea myrciifolia D.S.Costa & Farroñay, sp. nov. 

Recognition. Neea myrciifolia can be easily distinguished from all other species in the genus by a unique combination of vegetative and reproductive characters: opposite leaves with abaxial surface with a verrucose texture covered with sparse, pubescent to tomentose, reddish trichomes, globose 2-branched inflorescences with tubular staminate and pistillate flowers and patent, open, deltoid perianth lobes.

Etymology. The specific epithet "myrciifolia" refers to the vegetative resemblance, e.g. opposite leaves and brochidodromus venation, to the genus Myrcia DC. (Myrtaceae).

Recent fieldwork in eastern Sabah led to the discovery of new little-known crickets from the subfamily Pteroplistinae (Orthoptera, Grylloidea). Three new species are described: Tembelingiola biaculeata sp. nov. and Tembelingiola kabili sp. nov. from Sepilok; Pteroplistes silam sp. nov. from Mount Silam. Previously, the calling song of only one species of Pteroplistinae was known. Here, the calling songs of the three new species, as well as that of Pteroplistes lagrecai Gorochov, 2004, are also described for the first time. Therefore, distinctive calling songs for five species and three genera of Pteroplistinae are presently known.

Abstract

Akanthomyces Lebert belongs to the family Cordycipitaceae (Hypocreales, Sordariomycetes), which is regarded as one of the most important groups of entomopathogenic fungi (EPF). Despite the high fungal diversity in Sabah, Malaysia, the systematics and phylogeny of Akanthomyces in this region is still lacking. This study aimed to characterize entomopathogenic fungal specimens collected from Sabah using morphological and molecular phylogenetic approaches to determine their taxonomic status. During surveys of entomopathogenic fungi, two specimens infecting lepidopteran host were collected and examined using morphological characterization and molecular phylogenetic analyses. Five genetic markers, including the internal transcribed spacer (ITS) region, small subunit ribosomal RNA (SSU), translation elongation factor 1-alpha (TEF1-α), RNA polymerase II largest subunit (RPB1), and RNA polymerase II second largest subunit (RPB2), were amplified and sequenced to infer phylogenetic relationships. Phylogenetic analyses were conducted using Maximum Likelihood (ML) and Bayesian Inference (BI) based on individual and concatenated datasets (ITS–SSU–TEF1-α-RPB1–RPB2). The analyses consistently recovered the Bornean isolates as a distinct, well-supported lineage. Morphologically, the isolates are distinguished by robust, cream to pale-yellow branched synnemata, smaller perithecia, larger ellipsoidal conidia and filiform, multiseptate ascospores that disarticulate at maturity into cylindrical to slightly barrel-shaped part-spores at maturity compared with closely related species. Based on the combined morphological and phylogenetic evidence, Akanthomyces infaproensis sp. nov. is described from Sabah, Malaysia. The discovery of this new species expands the known diversity of Akanthomyces and highlights the tropical rainforests of Sabah as reservoirs of undescribed fungal diversity.

Abstract

Populations of Ingerana Dubois (Anura: Dicroglossidae) from Mizoram, northeastern India, have historically been assigned to Ingerana borealis (Annandale), however recent taxonomic reassessment questioned their identity. We evaluated these populations using an integrative approach combining external morphology and mitochondrial 16S rRNA sequence data. Phylogenetic analyses recovered the Mizoram population as a distinct lineage within Ingerana, while morphological comparisons revealed multiple diagnostic differences from recognised congeners. Based on these data, we recognise the Mizoram population as a distinct species. It differs from I. borealis, I. occidens, and I. tenasserimensis by a unique combination of body size, tympanic morphology, dorsal skin texture, and proportional morphometric characters. Our findings resolve the taxonomic identity of Ingerana populations from Mizoram and suggest that species diversity within the genus in northeastern India remains underestimated.

Abstract

Gastrodia keyiensis M.Khanal, D.Borah & Dev.Kumar sp. nov. is described from Keyi Panyor District, Arunachal Pradesh, northeastern India. The new species is morphologically allied to G. putaoensis but differs in having a broadly obovate basal part of the labellum with 6–7 prominent longitudinally thickened structures, and a distinct, thick, strongly incurved, narrowly oblong-ligulate, yellow apical part that is minutely papillate, with the apex rounded to obtuse (vs. an elliptic basal part with 3–5 parallel thickened lines, and a narrower apical part densely covered with yellow hairs, with the apex obtuse and densely covered with red papillae). A detailed morphological description, diagnosis, photographic illustrations, notes on distribution, habitat, phenology, and conservation status, together with comparisons with morphologically allied species, are provided to facilitate its identification.

DOI: doi.org/10.1016/j.revpalbo.2026.105716 

Highlights: 

• Araucaria benignae sp. nov. from the Cretaceous Crato Fossil Lagerstätte is proposed.

• Fossils come from two distinct ethnostrata of the Crato Formation limestone.

• Ovuliferous cones are preserved as compressions and iron oxide replacements.

• Cuticle micromorphology of ovuliferous complexes and parastichy numbers are studied.

• Wood anatomical characters of the cone peduncle is described.

Abstract

The Crato Fossil Lagerstätte in the Mesozoic Araripe Basin in northeastern Brazil comprises one of the most important fossil floras in the Early Cretaceous (Aptian) of equatorial Gondwana, distinguished by its preservation, taxonomic diversity and evolutionary significance. Although the taxonomic diversity among gnetophytes and early angiosperms is remarkable, the most frequent macrofossil remains are foliage and reproductive organs of Araucariaceae. Similar to other late Mesozoic ecosystems, it has been assumed that fossil-species of this family were major constituents and canopy-forming trees of the past vegetation. Here, we formally describe ovuliferous cones from this unit and establish Araucaria benignae sp. nov. In order to overcome the uncontrolled fossil sampling in the outcrops of the Crato Formation, Santana Group, we tentatively reallocated the ovuliferous cone specimens to ethnostrata within the C6 carbonate unit of the lacustrine limestone section using the ethnostratigraphic approach. Specimens are probably derived from the “lajão dos sete cortes” and the “lajão branco” ethnostrata, which would mean a minimum time interval of the presence of the new fossil-species of about 79–310 ka. In addition, the previously known fossil-species of Araucariaceae from the Crato Formation flora are supplemented for first considerations about putative whole-plant reconstructions in this assemblage. Although a confident whole-plant association between Araucaria benignae sp. nov. and any of the three known araucariaceous foliage species cannot yet be established, shared epidermal characters suggest a possible affiliation with Brachyphyllum obesum and/or B. sattlerae, highlighting the potential of the Crato Fossil Lagerstätte for future whole-plant reconstructions of Cretaceous Araucariaceae.
