Abstract

Background: Alloscopus is one of the genera within the subfamily Heteromurinae, recently recorded in Thailand and is currently represented by six species from two regions of the country. In the northern part, A. tetracanthus Börner, 1906 and A. thailandensis Mari Mutt, 1985 have been recorded from forested habitats. In the southern part, A. whitteni Jantarit & Sangsiri, 2020, A. namtip Jantarit & Sangsiri, 2020 and A. jantapasoae Jantarit, Nilsai & Manee, 2025 have been reported from a cave habitat, while A. sago Jantarit & Manee, 2025 was recently described from a sago palm forest.

New information: A new species, Alloscopus ramanai sp. nov., is described from central Thailand, based on an integrative taxonomic approach combining morphological and molecular data. The new species closely resembles A. tetracanthus Börner, 1906, sharing several diagnostic characters including a dark red ocular patch and PAO shape and the number of M and S series chaetae on the dorsal head. Additional similarities include the number of spiniform labral papillae, labial basis chaetae, the number of pseudopores on the manubrium, the number of central and lateral macrochaetae on Th.II, the number of central macrochaetae on Th.III and Abd.IV. However, A. ramanai sp. nov. can be clearly distinguished from A. tetracanthus by a unique combination of traits, including the number of lateral macrochaetae on Abd. III and Abd. IV and the number of chaetae on the anterior side of the ventral tube. A detailed diagnosis and illustrations of the new species are provided herein. A key for species of Alloscopus in Thailand is also included. The complete mitochondrial genome of A. ramanai sp. nov. is 14,757 bp in length and comprises 13 concatenated protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes and two ribosomal RNA (rRNA) genes. Phylogenetic analysis, based on mitochondrial genome data, indicates that A. ramanai sp. nov. forms a sister lineage to Alloscopus bannaensis Zhang, 2020. The description of this new species contributes to a more comprehensive understanding of Heteromurinae diversity in Thailand and underscores the need for expanded mitogenomic sampling across Collembola.

Alloscopus ramanai Nilsai, Jantarit & Jaitrong, sp. nov.

Diagnosis: Alloscopus ramanai sp. nov. exhibits the morphological similarity to A. tetracanthus Börner 1906, a species reported from Australia, Indonesia, Malaysia, Singapore, Papua New Guinea, India, New Britain, Micronesia and Thailand (Chiang Mai Province). Both species share several morphological characters, including a dark red eye patch with reddish to dark dot pigmentation, a semi-divided PAO, labial basis M1(m)m2rel1l2, four spiniform labral papillae, 4–5 central and 4–5 posterior mac on Th. II, six central mac on Th. III, two central mac on Abd. IV, 0–2 inner unpaired ungual teeth, the presence of teeth on the unguiculus, smooth chaetae on the tibiotarsi, a similar number of chaetae on the manubrium and 4–7 spines on the dens. However, Alloscopus ramanai sp. nov. can be distinguished from A. tetracanthus by the absence of eyes (vs. 1+1), orange dot pigmentation (vs. lack of pigmentation) and the presence of five macrochaetae on the “A” series of the dorsal head chaetotaxy (vs. four). Furthermore, A. ramanai sp. nov. can ...

Etymology: The new species was collected in the vicinity of the Rama 9 Museum, part of the National Science Museum, Thailand, which serves as the locality. The specific epithet ramanai is derived from the name of the Museum and is used as a noun in apposition, honouring the institution.

Abstract  

Lazy Toads of the genus Scutiger are a diverse group of alpine specialists in Asia. Despite continuous research on the taxonomy of the genus, the diversity is still underestimated. Integrating both molecular and morphometric analyses, we describe three new species of the genus Scutiger from the Gaoligong Mountain Range in Yunnan Province, China. Morphologically, these three species resemble S. gongshanensis, S. mammatus, and S. boulengeri, respetively, but they can be diagnosed from these recognized species and all other congeners by a suit of morphological characters, including the toe webbing status, numbers of pectoral glands and axillary glands with nuptial spines in breeding males, and the number of fingers covered with nuptial spines in breeding males. Additionally, they show considerable genetic divergences with respect to their morphologically similar species. We discussed the still underestimated diversity in Southwest China, the existing taxonomic problems of the genus, particularly regarding the validity and the whereabouts of type specimens of S. bangdaensis, S. biluoensis, and S. meiliensis, and we provide an updated key to all recognized species of China.

Amphibia, cryptic diversity, frog, Hengduan Mountain, southwest Yunnan, taxonomy 

Scutiger lisu sp. nov. Wang, Yu, and Che 

Etymology: The species name “lisu” is derived from the Chinese word 傈僳, which is the name of the main ethnic group across the range of the new species. We name the new species after the local ethnic group to honor theharmony between the local ethnic culture and nature ecosystem. The proposed Chinese name of the new species is傈僳齿突蟾 (pinyin: Li Su Chi Tu Chan), and the proposed english name is Lisu Lazy Toad.  

Scutiger pardalotus sp. nov. Wang, Yu, and Che 

Etymology: The species name “pardalotus” is derived from greek, which means “spotted like a leopard”. Itdescribes the beautiful spotted coloration patterns on the dorsum of the species. The proposed Chinese commonname of the new species is “豹斑齿突蟾” (pinyin: bao ban Chi Tu Chan), and the proposed english name isLeopard Lazy Toad.  

Scutiger ching sp. nov. Wang, Yu, and Che 

Etymology: The species name, ching, is derived from the language Trung, the language of the local ethnic minority group (Dulong) at the type locality of the new species. It means small and slender, which describes thediagnostic body shape of the new species. We chose the native language of the Dulong People to honor the harmonybetween the local ethnic culture and nature ecosystem. We suggest elf Lazy Toad as its english common name, and“山精齿突蟾” (Pinyin: Shan Jing Chi Tu Chan) as its Chinese common name.

in Patil, Kadam, Jangam, Dive et Mane. 2026. 

 DOI: doi.org/10.1002/njb.05075  

Abstract

Lepidagathis konkanensis, a new species from the lateritic plateaus of the Konkan region in Maharashtra, India, is described and illustrated based on distinct morphological and molecular characters. Morphologically and phylogenetically, this species is close to L. mahakassapae and L. dalzelliana, but it can be distinguished by its compact inflorescence, oblanceolate leaves, bilabiate yellow corolla, elliptic-lanceolate bracteoles with three nerves, shorter style and smaller seeds. In addition, the longer branch length observed in the phylogenetic tree further supports the presence of molecular divergence. Detailed morphological descriptions, illustrations and color plates of field photographs and floral part micrographs are provided to aid in precise identification. The IUCN conservation status has also been assessed to emphasize the need for conservation measures.

Pachyrhynchus analynae Obrial, Agbas, Pajota & Medina sp. nov.

Diagnosis: Pachyrhynchus analynae sp. nov. belongs to the P. speciosus species group. In general appearance, this novel species conspicuously resembles a cross between P. miltoni Cabras & Rukmane, 2016, from Marilog, Davao City, and P. cabrasae Rukmane, 2016, from Mt. Kalatungan, Bukidnon. It exhibits a combination of scaly maculations found in both congeners: the longitudinal scaly bands at pronotum which resembles P. miltoni, while reticulate scales at elytra resembles P. cabrasae. However, P. analynae sp. nov. differs with P. miltonibased on the following characteristics: amygdaloid elytral shape, narrower in profile, and tapers apically; elytra bears reticulate net-like maculations that merge and sparsely covered with setae from the apical declivity towards the apex (vs stouter elytra with minute setae only along the lateral margin; with open-and closed-banded variations, with three contiguous scaly bands, with open-banded variation that retains the three scaly bands in P. miltoni).

Abstract

Psalidodon rivularis, a fish endemic to the São Francisco River Basin and known as “piaba do córrego,” has long been regarded as a widely distributed species complex, exhibiting remarkable morphological and cytogenetic variation, even in sympatry. This study aims to determine whether P. rivularis represents a single polymorphic species or a group of cryptic species. We analyzed meristic, morphometric, and karyotypic data from 419 specimens identified as P. rivularis, as well as from the related species Astyanax turmalinensis and Hyphessobrycon santae. Additionally, we inferred the phylogeny of the group using NGS data from 25 individuals, incorporating both mitochondrial and nuclear genomic sequences. Our integrative results support the recognition of at least five distinct species within the P. rivularis complex. The true P. rivularis (called morphotype 1) has 46 chromosomes, while the others have 50 and differ in both morphology and distribution. One of these corresponds to Psalidodon santae comb. nov.—which includes A. turmalinensis as a junior synonym—and three others are newly described species. These findings clarify the diversity of fishes in the São Francisco River Basin and highlight the importance of conserving its unique freshwater ecosystems.

Simple Summary: This study investigates a group of closely related fish species from southeastern Brazil known as the Psalidodon rivularis complex. These fishes are very similar in appearance, which has made it difficult to know exactly how many species exist. By combining information from their body shape, body measurements, chromosome counts, and DNA, we found that what was once thought to be a single species includes at least five distinct ones. The true P. rivularis has 46 chromosomes, while the others have 50. One of them corresponds to Psalidodon santae, which was previously classified in another genus, and three are new species described here. Our results also suggest that their diversity arose through processes such as changes in chromosome numbers, hybridization between populations, and morphological divergence, potentially within broader scenarios that may involve vicariant or adaptive processes. These fishes live in small rivers and streams of the Upper São Francisco River basin, environments that are rich in unique species but threatened by human activities. Recognizing and protecting these new species is essential for conserving the biodiversity of Brazilian freshwater ecosystems.

in Sajikumar, Sasikumar, Ameri et Thomas, 2025. 

DOI: doi.org/10.1007/s12526-025-01576-3

Abstract

A new species of the genus Taningia Joubin, 1931 (family Octopoteuthidae Berry, 1912), is described from the southeastern Arabian Sea, based on a single specimen collected in March 2024 at a depth of 390 m. This new species, Taningia silasii sp. nov., differs from congeners in a combination of traits, including the shape of the funnel-mantle locking cartilage, nuchal-locking cartilage, lower beak morphology, gill lamellae count, and distinct genetic divergence as revealed by phylogenetic analysis of mitochondrial COI and 16S rRNA genes, with uncorrected p-distances of 11.8–12.1% (COI) and 4.3–4.5% (16S rRNA) from T. danae. Phylogenetic trees clearly separate Taningia silasii sp. nov. from Atlantic Ocean lineages of T. danae, supporting its recognition as a distinct species. The genus Taningia appears to represent a species complex, comprising the newly described Indian Ocean lineage and at least two distinct lineages from the Atlantic Ocean. These findings, based on integrated morphological and molecular analyses, highlight hidden diversity within Taningia and expand the known biogeographic range of the genus.

We illustrate adult specimens of all described taxa of A. pyrrhosticta n. sp., A. eresia (C. Felder & R. Felder, 1862) and A. hilaris Jordan, 1910, and representatives of A. trinacria (C. Felder & R. Felder, 1862). We also provide illustrations of male and female genitalia for select taxa, distribution maps, and a revised, annotated synonymic list for all four species.

Abstract

We describe two large predators from the hominoid-bearing Khorat sand pits, Nakhon Ratchasima Province, northeastern Thailand: a new genus of pantherine, Pachypanthera n. gen., represented by partial mandible and maxilla and an indeterminate sabre-toothed cat, represented by a fragment of upper canine. The morphological characters of Pachypanthera piriyai n. gen. n. sp., notably the large and powerful canine, the great robustness of the mandibular body, the very deep fossa for the m. masseter, the zigzag HSB enamel pattern, indicate bone-cracking capacities. The genus is unique among Felidae as it has one of the most powerful and robust mandibles ever found. Moreover, it may be the oldest known pantherine, as other Asian pantherines are dated back to the early Pliocene. The taxa we report here are the only carnivorans known from the late Miocene of Thailand. Although the material is rather scarce, it brings new insights to the evolutionary history of Neogene mammals of Southeast Asia, in a geographic place which is partly “terra incognita.”
