Abstract

We herein describe a new species of spiny frog, Quasipaa yunkaiensis sp. nov. from Yunkaishan National Nature Reserve, Xinyi City, Guangdong Province, China. Morphological examination combined with mitochondrial (810 bp Cyt b) and nuclear (1 852 bp concatenated Rag2, Tyr, and Rhod) genetic data was used to test its distinctiveness within Quasipaa. Morphologically, the new species differs from other congeners by the following diagnostic characteristics: relatively large body size within Quasipaa; dorsal skin relatively smooth, having sparse tubercles; lacking spiny tubercles on the ventrolateral sides of the body; lacking keratinized spines in the ventral surface of the body, only present on prepollex, fingers I and II, in breeding males. Both mitochondrial and nuclear phylogenetic results indicate that Quasipaa yunkaiensis sp. nov. constitutes a highly supported, deeply divergent lineage, but its precise phylogenetic placement within the genus Quasipaa remains unresolved. In view of the pronounced discordance between mitochondrial and nuclear datasets within Quasipaa, we encourage future studies to use genome-wide data to improve phylogenetic resolution and to estimate species diversity more accurately.

The Yunkai Spiny Frog (Quasipaa yunkaiensis) is a newly described species discovered from the Yunkaishan Nature Reserve, Xinyi City, Guangdong Province, China. This species inhabits montane stream environments within evergreen secondary forest at elevations between 1 200–1 550 m. It is currently only known from its type locality. Although mito-nuclear discordance has been reported in several species of the genus Quasipaa, both mitochondrial and nuclear gene fragments consistently recover Q. yunkaiensis as a distinct evolutionary lineage. This new species was reported by Shuo QI et al. in this issue. This frog was drawn by Hanwen KANG and Timan YANG.

The first fossil representatives of the harvestman subfamily Ortholasmatinae (Opiliones, Dyspnoi, Nemastomatidae) are described as Balticolasma wunderlichi gen. et sp. nov. One male is preserved in Eocene Baltic amber and a presumably conspecific female in Eocene Rovno amber (northwest Ukraine). Ortholasmatines are typically highly ornate arachnids, and for the first time with an amber harvestman we applied computed tomography using synchrotron radiation to investigate its three-dimensional morphology and surface structure in considerable detail. Some of its morphological characters, appear to be closer to extant Asian genera. In a wider biogeographic context, our amber record is a significant find for the Paleogene of Europe given that (i) it is another species apparently found in both Baltic and Rovno amber and (ii) all modern ortholasmatines are restricted to East Asia and North and Central America.

Abstract 

We describe teleosaurid remains from the Middle to Upper Jurassic Khlong Min Formation at Ban Nam Pun in southern Thailand and define Indosinosuchus peninsularensis sp. nov. This new species is diagnosed by a unique combination of cranial and postcranial features, including the nasal reaching anteriorly at the level of the 18th maxillary alveolus, absence of an incisive foramen, oval-shaped external nares, and broad ornamented osteoderms. Phylogenetic analysis positions I. peninsularensis within a polytomy alongside Mystriosaurus laurillardi and other Asian teleosaurids, supporting a monophyletic Teleosauroidea. In addition, the revision of Indosinosuchus kalasinensis as a junior synonym of I. potamosiamensis also strengthens the taxonomic framework of the genus Indosinosuchus. Indosinosuchus peninsularensis sp. nov., discovered in a low-energy lagoonal environment, offers significant insights on the ecological preferences of teleosaurids. In contrast to the fluvially deposited Phu Kradung Formation of northeastern Thailand, the lagoonal and marginal marine sediments of the Khlong Min Formation are considered indicative of a broad spectrum of habitat occupation by Asian teleosauroids. Based on these observations, a high degree of ecological plasticity has been inferred for Thai teleosaurids, and their extensive dispersal across both the Sibumasu and Indochina terranes during the Middle to Late Jurassic has been further substantiated. The recognition of I. peninsularensis sp. nov. contributes to our understanding of teleosaurid diversity and paleobiogeography in Southeast Asia.

[Fungi • 2026] Gibellula mineira • The Silent Hunters of Spiders: Discovering A New Gibellula (Ascomycota: Cordycipitaceae) Fungus in the Brazilian Atlantic Forest

Abstract

In tropical forests, there is a high diversity of parasites that use arthropods as resource, particularly arachnids. One of the most frequent groups of spiders’ parasites in tropical forests are fungi of the genus Gibellula, for which a considerable knowledge gap remains in these environments. In this study, we present the description of a new species that infects spiders of the species Iguarima censoria (Anyphaenidae) in the Brazilian Atlantic Forest, Gibellula mineira sp. nov. We also described the prevalence of the new fungal species in the host spider population and evaluated whether the host size influences their probability of parasitism. Morphological and molecular analyses revealed that G. mineira represents a distinct species forming a clade with 100% support of bootstrap and showing a close phylogenetic relationship with Gibellula aurea. The characteristics that distinguish it from other species of the genus include light brown hyphae, white and slightly larger conidiophores, and thinner phialides. We observed a high prevalence of parasitism in this interaction, reaching 25% of the observed I. censoria population. Furthermore, we noted that the cadavers of parasitized spiders are exclusively attached to the underside of leaves, following the typical pattern observed for Gibellula species. Parasitism is more frequent in smaller I. censoria individuals, which is probably associated with thinner cuticles or higher foraging activity in smaller individuals. We suggested that G. mineira is an important natural enemy of I. censoria, directly influencing the population dynamics of this spider and expanding our knowledge of the ecology and biodiversity of araneopathogenic fungi.

DOI: doi.org/10.3897/fr.29.178152 

Abstract

The Korean dinosaur fossil record is exceptionally rich in trackways and eggs, yet skeletal remains are exceedingly rare. Two species have been described based on postcranial elements, and a taxon known from cranial materials has not yet been reported. Here, we report a new early-diverging neornithischian species, known from a small, partially articulated skeleton comprising cranial and postcranial elements as well as gastroliths. The specimen is from the mid-Cretaceous Ilseongsan Formation of Aphae Island (Aphaedo). X-ray micro-computed tomography (micro-CT) revealed the anatomy of the new species, including the first studied cranial remains of a dinosaur from Korea. The size and anatomical features of the specimen, along with histological analysis, indicate that it is not a fully grown individual, probably 0–2 years old. Gastroliths are present, with morphologies and a relative mass proposed to be consistent with a more omnivorous diet. Phylogenetic analyses recover the new species, Doolysaurus huhmini gen. et sp. nov., as a thescelosaurid. The recovery of Doolysaurus with most other Asian thescelosaurids near the base of this clade provides further evidence for its origin and early biogeography. The new discovery suggests that other small dinosaur fossils may be found at Aphaedo or at sites with similar taphonomic conditions in Korea; Doolysaurus is consistent with richer dinosaurian diversity in the Cretaceous of Korea than is represented in its rich trace fossil record.

Diagnosis. Doolysaurus huhmini is a small-bodied, early-diverging neornithischian dinosaur with the following unique combination of features recovered from analysis of the Fonseca et al. (2024) dataset, including one optimized autapomorphy (*): (1) the lateral condyle of the quadrate is larger than the medial condyle (shared with Orodromeus and Haya) (ch.196:2); (2) Exoccipital, relative positions of the exits of the hypoglossal nerve (XII) combined into a single exit (shared with Jeholosaurus) (ch. 254:2); (3) Basioccipital, contribution to the border of the foramen magnum more than 1/3 its basioccipital condyle size (shared with Fona) (ch. 261: 0); (4) the apex of the maxillary teeth is located posterior to the center (shared with ...

Etymology. The generic name Doolysaurus honors “Dooly the Little Dinosaur,” an iconic Korean cartoon baby dinosaur character created by Soo-Jung Kim in 1983; saurus is from the Greek σαῦρος (sauros), meaning “lizard.” The specific name, huhmini, honors Professor Dr. Min Huh, a paleontologist who conducted research on a theropod fossil nest from the Aphaedo site, in recognition of his outstanding contributions to the study of dinosaurs in Korea over the past 30 years.

[Ichthyology • 2026] Formosania tangi • A New Species of Suck-loach (Cypriniformes: Gastromyzontidae) from the Jiulongjiang River, southeastern China

Formosania tangi

Abstract

For decades, populations of the suck-loach genus Formosania from the Jiulongjiang River in Fujian Province, China, have been identified as F. fascicauda, a species originally described from in a separate coastal drainage basin in Fuqing County. Employing an integrative taxonomic approach combining morphological and molecular phylogenetic analyses, we demonstrate that the Jiulongjiang River population represents a distinct species, formally described here as Formosania tangi sp. nov. It is diagnosed by a combination of characters: 13 rostral barbels arranged in two rows, a distinct straight, dark, longitudinal stripe along the lateral line, and an emarginate caudal fin. Phylogenetic analyses consistently recover it as a unique evolutionary lineage showing significant genetic divergence from true F. fascicauda, with a Kimura 2-parameter distance of 4.16%. The description of F. tangi clarifies the taxonomic status of the Jiulongjiang River population and enhances our understanding of species diversity and biogeography of Formosania in the coastal drainages of southeastern China.

Diagnosis. The new species can be distinguished from congeners by combination of following characters: rostral barbels 13, well developed, arranged in two rows (Fig. 3B) (vs one row in F. davidi, F. fasciolata, F. galericula, and F. immaculata – Fig. 3A; 12–15 rudimentary barbels in F. chenyiyui – Fig. 3C); lateral line accompanied by broad, dark, longitudinal band, margins weakly undulating or nearly straight, pale stripe between lateral line band and dark dorsal surfaces ...

Etymology. The species name honours Wen-Qiao Tang, a senior Chinese ichthyology researcher, and is derived from the latinized Chinese spelling of his family name, in recognition of his contributions to the field. We propose “Wén Qiáo Yīng Kŏu Qiū” (文乔缨口鳅) as its Chinese common name.

Abstract

Recent field work in Sabah state of Malaysia in Borneo, as well as Mindanao, Negros and Siquijor Islands in the Philippines has led to the collection of crickets from the family Phalangopsidae. This allows us to review the taxonomy of Luzonogryllus Yamasaki, 1978 from the Philippines and Sabah. We also describe a new species from Mindanao: Luzonogryllus (Apterozacla) appa Tan & Alo, sp. nov. We also present new locality records for Luzonogryllus (Apterozacla) mindoroensis Gorochov, 2006 in Negros and Siquijor Islands. Lastly, we also present new material of Strophiola lugubrina (Stål, 1877) from Mindanao and Negros Islands.

Abstract

Hemiphyllodactylus Bleeker 1860, one of the fastest-growing genera in the Gekkonidae, comprises 22 species distributed in China, among which Hemiphyllodactylus yunnanensis is believed to be a species complex. Despite the gradual description of Hemiphyllodactylus populations in various regions of China as new species in the past decade, the taxonomy of the Hemiphyllodactylus yunnanensis complex remains unresolved. We collected Hemiphyllodactylus populations of the yunnanensis complex from 11 locations. Based on 1809 bp dataset (1039 bp mitochondrial ND2 gene, fragments of 375 bp nuclear C-mos + 395 bp PDC genes) and a solo 1039 bp NADH dehydrogenase subunit 2 (ND2) sequence fragment dataset, the constructed phylogenetic topology revealed that our samples fell into seven independent lineages of Clade 7. Automatic Barcode Gap Discovery (ABGD) results are consistent with our phylogenetic findings. The uncorrected genetic pairwise distance between populations exceeded 4.2% in ND2 gene, and there were also significant morphological differences among them. Therefore, we consider the specimens that cluster with the topotype specimens as true Hemiphyllodactylus yunnanensis, and describe the other six lineages as new species, respectively.
