Abstract

A new species of the agamid genus Diploderma Hallowell, 1861 is described from Gula Township, Zayü County, Xizang Autonomous Region (Tibet), China, based on integrated morphological and molecular evidence. Phylogenetic analyses of mitochondrial ND2 genes reveal that the new species Diploderma gulaense Cai, Yao, Wu & Guo, sp. nov. forms a well-supported clade with D. laeviventre, D. yangi, and D. slowinskii, endemic to the Nu River valley. It is sister to D. laeviventre but differs from it and other congeners by a combination of morphological characteristics: moderate body size (SVL 53.1–63.4 mm in males, 54.8–70.2 mm in females); relatively long tail (TAL/SVL 2.07–2.38 in males, 1.90–2.26 in females); tympanum concealed; ventral body scales strongly keeled; transverse gular fold present; cyan gular spot in both sexes; pale cyan dorsolateral stripes in males; and tongue pale flesh colored. The new species is currently known only from the Ranbuqu valley, a dry-warm valley along a tributary of the middle Nu River, at elevations between 2,332 and 3,300 m. Its restricted distribution and ongoing habitat degradation suggest a preliminary IUCN assessment of Vulnerable (VU). The discovery of Diploderma gulaense Cai, Yao, Wu & Guo, sp. nov. further highlights the role of river-valley systems in driving allopatric speciation within the genus and underscores the underestimated diversity of Diploderma in the Hengduan Mountains.

Diploderma gulaense Cai, Yao, Wu & Guo, sp. nov.

Diagnosis. Diploderma gulaense sp. nov. can be diagnosed from its congeners by a combination of the following morphological characteristics: (1) adult body size moderate, SVL 53.1–63.4 mm in males (n = 4), 54.8–70.2 mm in females (n = 7); (2) tail relatively long, TAL/SVL 2.07–2.38 (mean 2.18) in males, 1.90–2.26 (mean 2.02) in females; (3) head moderately depressed, HW/HL 0.65–0.75 in males, 0.65–0.74 in females; (4) foreleg length moderate, FLL/SVL 0.46–0.48 in males, 0.43–0.50 in females; (5) hindleg length relatively short, HLL/SVL 0.74–0.80 in males, 0.66–0.77 in females; tympanum concealed by small scales; (6) middorsal crest scales ....

Etymology. The Latin specific epithet gulaense is derived from the Gula Township, where the new species was discovered. The genus Diploderma is Greek neuter, and the suffix -ense of this new species name is the Latin neuter combinatorial suffix denoting ‘pertaining to’ or ‘originating in’. 

And we suggest Gula Mountain Lizard as its English common name and 古拉攀蜥 (Chinese phonetic alphabet: gǔ lā pān xī) as its Chinese common name.

Abstract

Typhlopidae is the most species-rich and broadly distributed family of blind snakes. Due to their secretive habits, fossorial lifestyle, and conserved morphology, the taxonomy and systematics of this group remain poorly understood. Here, a new species of blind snake is described from Xizang, China, based on morphological comparisons and molecular phylogenetic analyses. The new species is genetically divergent from its closest relatives with an uncorrected CO1 p-distance exceeding 18.3%. Morphologically, it can be diagnosed by a combination of the following characters: 1) large size with 265 mm total length, 2) supralabial imbrication pattern T-V, 3) midbody scales in 18 rows, 4) total middorsal scales 432, 5) subcaudals 17, 6) infralabials 2, 7) absence of a terminal tail spine, and 8) light-colored head cap. Currently, the new species is known only from Xizang, China, but it likely occurs in adjacent regions in Nepal.

Indotyphlops gyirongensis sp. nov.

Diagnosis. A blind snake distinguished from congeners by a combination of characters: 1) large size with 265 mm in total length, 2) SIP T-V, 3) midbody scales in 18 rows, 4) total middorsal scales 432, 5) subcaudals 17, 6) infralabials 2, 7) absence of a terminal tail spine, and 8) light-colored head cap.

Etymology. The specific epithet Gyirong is a noun in apposition, referring to the type locality, Gyirong Town, Gyirong County, Xizang, China. We suggest the English common name “Gyirong blind snake” and the Chinese common name “吉隆盲蛇” (Jílóng Mángshé) for this new species.

[Herpetology • 2026] Eremiascincus erebos • A New banded skink (Scincidae: Sphenomorphini) from sandstone habitats of the Gulf of Carpentaria, Australia

 

Eremiascincus erebos

Abstract  

We describe Eremiascincus erebos sp. nov., a new species of banded, crepuscular and nocturnal skink from sandstone habitats of the southern Gulf of Carpentaria region in the Northern Territory, Australia. The species is known to inhabit scree and deep, cave-like crevices in gorges and rock towers. Morphology and genomic sequence data indicate E. erebos sp. nov. is most closely related to E. fasciolatus—with which it shares divided posterior supralabials, a character otherwise absent in Eremiascincus—but differs in having a larger ear opening, no ridges along the dorsal surfaces of the hindbody and tail, and a higher midbody scale row count. Although currently known from only two localities in the north-eastern Northern Territory, E. erebos sp. nov. is likely more widespread across the region south of the Gulf of Carpentaria.

Eremiascincus erebos sp. nov. in life and associated habitat:
 (A) MAGNT R36326 (holotype) and (B) MAGNT R36327 (paratype) from Pungalina–Seven Emu Sanctuary; (C) an unvouchered individual from Caranbirini;

Photos: S. Mahony (A), W. Read (B), M. Clancy (C), S. Zozaya (D).

 Eremiascincus ereboss sp. nov. 

Diagnosis. Can be differentiated from all other Eremiascincus by the following combination of characters: irregular, dark, transverse bands on dorsal surface of body and original tail; dark bands on torso 1–2.5 scales wide; 37–39 MBSR; 8–9 supralabials, the penultimate and/or posteriormost being divided horizontally; ear opening very large (ear height 33–34% head depth) and elliptical; scales on dorsal surface of fourth toe arranged in multiple rows with oblique sutures, with only the terminal and penultimate scale row single; dorsum and tail completely lacking longitudinal ridges; snout rounded in lateral view, not depressed.

 Etymology. From the Greek ἔρεβος (erebos), used by Homer in the Iliad for the dark, gloomy passages between Earth and Hades, in reference to the dark sandstone crevices and caves in which this species is often found. The epithet was intentionally chosen for its phonetic resemblance to the generic name Eremiascincus, with both names beginning with ere- despite deriving from different Greek roots. The name is used as a noun in apposition. Coincidentally—and unknown to us until we compiled the reference list for this paper—the related species E. pallidus (Günther, 1875) was described in The Zoology of the Voyage of HMS Erebus and Terror, which refers to a ship bearing the same name in its Latinised form. 

We recommend the common name 'Garrwa Banded Skink' given that the species' known extent of occurrence falls mostly within Garrwa country. We thank Daphne and Peggy Mawson, Garrwa Elders, for their ongoing support toward understanding the lizard diversity on their country.

Abstract

Alfred’s blind skink, Dibamus alfredi Taylor, 1962, and Somsak’s blind skink, Dibamus somsaki Honda, Nabhitabhata, Ota & Hikida, 1997, are two poorly known and rarely recorded members of the family Dibamidae endemic to Thailand. Since their original descriptions based on specimens collected in Pattani Province in 1960 and Chanthaburi Province in 1995, respectively, both species have remained extremely elusive and no molecular data have been available to date. Here, we report new records of D. alfredi from Yala Province in southern Thailand and of D. somsaki from Chanthaburi Province in eastern Thailand, providing important new locality data for these rare Thai endemics. Based on newly collected material, we present revised diagnoses and detailed redescriptions of both species and provide osteological descriptions of D. alfredi and D. somsaki based on micro-CT data for the first time. In addition, we present the first molecular data for both species based on mitochondrial DNA sequences of three gene fragments (16S rRNA, ND2, and COI) and reconstruct an updated phylogeny of the family Dibamidae. Our analyses confirm that D. alfredi and D. somsaki represent two deeply divergent evolutionary lineages within the genus Dibamus.

Abstract

Using an integrative dataset of both mitochondrial DNA and morphological data, we describe a new species of the genus Acanthosaura from the China-Myanmar border region in Menglian County, Pu’er, Yunnan Province, China. The new species, Acanthosaura aurantiogularis sp. nov., is sister to A. tongbiguanensis, and it can be readily diagnosed from all recognized congeners by its bright orange gular coloration in the male, flesh colored oral cavity, moderate post-orbital spines and occipital spines, five or six well-developed nuchal crest scales, and a distinct dorsal coloration. We recommend further comprehensive phylogenetic studies of the genus and highlighted the understudied agamid diversity in northeastern Myanmar.

Acanthosaura aurantiogularis Wang, Lu & Che, sp. nov.

Diagnosis. Acanthosaura aurantiogularis sp. nov. can be diagnosed from congeners by a combination of the following morphological characters: (1) tail short, TAL 167% SVL in female; (2) length of post-orbital and occipital spines moderate, LOPS 11.0–15.1% HL, LLOC 9.5–15.9% HL; (3) nuchal crest erected, 5 or 6, discontinuous from dorsal crests, TNCL 13.8–18.7% HL; (4) diastema short, composed of 6–8 small scales; (5) dorsal crest erected, anterior most one shorter than nuchal, decreasing in length posteriorly; (6) enlarged middorsal crest scales 41; (7) gular pouch moderately developed, transverse gular fold ...

Etymology. The specific epithet aurantiogularis is a compound Neo-Latin adjective derived from the Latin aurantius, meaning “orange-colored,” and gularis, meaning “the throat”. This nomenclature is a direct descriptor of the lizard’s most striking and diagnostic morphological feature: the vibrant, unmarked orange-yellow gular pouch in males. The suggested Chinese common name is “橙喉棘蜥” (Pinyin: Chéng Hóu Jí Xī), and the suggested English common name is Orange-throated Pricklenape.

Abstract

A remarkable new species of skink, Scincella gigas sp. nov., is described from Yunnan Province, China, based on integrative morphological and molecular evidence. The new species represents the largest known member of the genus Scincella, with the adult female holotype attaining a snout-vent length of 125 mm and a total length exceeding 316 mm despite possessing a partially regenerated tail. Scincella gigas sp. nov. can be distinguished from all congeners by a unique combination of morphological characters, including three prefrontal scales, relatively short limbs that fail to meet when adpressed, the third pair of chin shields separated by four small scales, 28 midbody scale rows, 80 paravertebral scale rows, and broad dorsolateral stripes with distinctly serrated margins. Phylogenetic analyses based on concatenated mitochondrial gene fragments (12S, 16S, CO1, and Cyt b) recovered the new taxon as a distinct lineage within Scincella, although its precise phylogenetic relationships remain unresolved. The new species exhibits substantial genetic divergence from all examined congeners (≥ 4.4% in 16S and ≥ 14.2% in CO1). Scincella gigas sp. nov. is currently known only from montane mixed forests and associated alpine meadows in Fengyi Town, Dali Bai Autonomous Prefecture, Yunnan Province, China, at an elevation of 2,790 m a.s.l. The discovery of such a conspicuous and exceptionally large species suggests that the diversity of montane Scincella in southwestern China remains insufficiently documented.

Diagnosis. Scincella gigas sp. nov. represents the largest known member of the genus Scincella, with the adult female holotype attaining an SVL of 125 mm and TL exceeding 316 mm. The new species can be distinguished from all other congeners by the following combination of characters: (1) exceptionally large body size, with the adult female holotype attaining an SVL of 125 mm; (2) three prefrontal scales; (3) six supraciliaries; (4) seven supralabials, separated from the eye by a row of small scales; (5) six infralabials; (6) tympanum deeply recessed and lacking lobules, with the tympanum diameter exceeding that of the palpebral disc (TD/PDD ratio 1.45); (7) three pairs of chin shields, with the third pair separated medially by four small scales; (8) 28 midbody scale rows; (9) total ventral + gular scale rows numbering 81; (10) 80 paravertebral scale rows; (11) relatively short limbs, with toes not in contact with fingers when the limbs are adpressed (FLL+HLL/AGD ratio 0.57); (12) 9–10 enlarged subdigital lamellae beneath Finger IV and 13 beneath Toe IV; and (13) in life, dorsum brown, with relatively broad dorsolateral stripes bearing distinctly serrated margins.

Etymology. The specific epithet “gigas” is derived from the Latinized form of the Greek noun γῐ́γᾱς (gígas), meaning “giant.” The name refers to the exceptional size of the new species, which represents the largest known member of the genus Scincella. 

In reference to this remarkable characteristic, “Giant Ground Skink” is proposed as the English common name, “гигантский малый сцинк” (gigantskiy malyi stsink) as the Russian common name, and “巨滑蜥” (Pinyin: jù huá xī) as the Chinese common name for the new species.

Abstract  

Nanlingophis nvwa gen. et sp. nov., a new genus and species of the family Dipsadidae, has been identified based on a specimen collected from Tianjingshan National Forest Park in Guangdong Province, southern China. Nanlingophis is assigned to Dipsadidae based on its phylogenetic placement, currently monotypic and it is diagnosed by the following combination of characters: body slender; tail long, TaL/TL 0.314; dorsal scales smooth, rhomboid and juxtaposed, in 13 rows throughout the body; ventrals 163; anal shield divided; subcaudals paired, 110+1 pairs; supralabials 5/5, with the 3rd and 4th entering the orbit; infralabials 5/5; suboculars absent; loreal single and crescent-shaped; temporals 1+1+2; rostral not dorsally recurved; anterior nasal plates not expanded; dorsum yellowish brown, each scale edged dark brown to blackish and forming a reticulate pattern. This combination of characters distinguishes the new genus from all superficially similar genera, especially Stichophanes, Thermophis, Dipsas, Pareas and Aplopeltura.

Common English Name: Nvwa slender snake.

Common Chinese Name: 女娲纤蛇 (nǚ wā xiān shé).

Etymology: The specific epithet nvwa is derived from “Nüwa”, a significant deity in Chinese mythology traditionally revered as the creator and protector of life. This is nomenclature was selected to honor the cultural heritage of theYao people residing in the autonomous county where the type specimen was discovered, as some members of thiscommunity trace their ancestry to Nüwa. The nearby Mangshan Yao communities traditionally venerate snakes,a symbol closely linked to Nüwa in folklore. The epithet is used as a nominative noun in apposition and remainsindeclinable.

Abstract

A new species of mountain horned dragon, Acanthosaura syrax sp. nov., is described from the high–elevation evergreen forests of Mae Wong National Park in western Thailand. Morphological comparisons distinguish the new taxon from its congeners by its smaller body size and the fact that it possesses the smallest nuchal and dorsal scales recorded within the genus. Phylogenetic analysis of mitochondrial ND2 and COI gene sequences further supports this distinction, identifying the new species as a reciprocal monophyletic lineage with 76% and 99% nodal support in maximum–likelihood analyses and 0.78 and 1.00 nodal support in Bayesian Inference analyses based on ND2 and COI genes, respectively. Interspecific pairwise genetic distances between A. syrax sp. nov. and other congeners range from 14.1–15.9% in ND2 gene and 14.96–28.13% in COI gene, while intraspecific variation remains low at 0–0.01% and 0–0.34% in ND2 and COI, respectively. This discovery brings the number of Acanthosaura species to 23 and highlights the significant and unique biodiversity found within the high–altitude evergreen ecosystems of western Thailand.

Etymology. The specific epithet syrax is a noun in apposition, named in reference to the dragon “Syrax”, the mount of Queen Rhaenyra Targaryen [from George R.R. Martin’s A Song of Ice and Fire universe]. This name is inspired by the species’ distinctive yellow-hued coloration, its relatively diminutive size compared to its congeners, and its significant reproductive output, reflected in its high clutch size. We suggest the following common names, “Syrax mountain horned dragon” (English) and “King Ka Khaow Naam Lek Syrax” (กิ้งก่าเขาหนามเล็กไซแรกซ์) (Thai).

 Abstract  

One challenge for species delimitation involves closely related species, characterized by both intra- and interspecifically variable morphologies, for which genetic information is not yet available. One such example is exhibited by agamid lizards of the genus Bronchocela. This group of conspicuously vibrant green lizards is widely distributed in Southeast Asia, with 15 recognized species. However, the geographic distributions of several named taxa have remained unclear because of the imprecise application of names in taxonomic summaries and faunal checklists. For more than a century, many authors have noted that a few species, often considered “widespread,” persist throughout nearly the entire range of the genus. This is particularly true for populations identified as Bronchocela cristatella sensu lato and, to a lesser extent, B. marmorata in the Philippines. In this study, we reassess the systematics and taxonomy of Bronchocela populations in the Philippine archipelago. Using multiple lines of evidence from molecular and morphological data, we uncover four distinct lineages of Philippine Bronchocela, all of which we interpret as being distantly related to B. cristatella sensu lato from Malaysia and Indonesia. We argue that these lineages should now be interpreted as Philippine endemic species. Given the strong congruence in molecular and morphological analyses, we now consider populations from the Luzon faunal region (including Catanduanes, Marinduque, Lubang, and Polillo Islands), Romblon (Tablas, Romblon, and Sibuyan Islands), and the West Visayas (Negros, Cebu, and Panay Islands) as B. marmorata. The nomenclaturally available name, B. philippina, is now designated to the unique lineage from the Mindanao faunal region. Additionally, we recognize two new, distinctive species from the Mindoro (B. carestiai) and Palawan (B. mallarii) faunal regions. Overall, our findings demonstrate how conspicuous and widely distributed species in Southeast Asia remain poorly understood, overlooked, and taxonomically unresolved. Hence, the taxonomic resolution of Bronchocela populations in the island archipelagos of Southeast Asia will greatly benefit from the urgent priority of determining which landmass the name “B. cristatella” applies.

Abstract

Previous studies have indicated the polyphyly of Scincella modesta and reported a new record of Scincella vandenburghi in Qingdao, Shandong Province. Furthermore, the research highlighted significant morphological similarities between the Qingdao population of S. vandenburghi and a branch of S. modesta from Hubei, leaving the taxonomic boundaries between these two species unclear. To better understand the relationship between S. modesta and S. vandenburghi, we conducted extensive sampling in the Dabie Mountains, which geographically lie between Qingdao, Ningbo and Yichang. Based on phylogenetic analyses and morphological comparisons, we identify an undescribed species of the genus Scincella from the Dabie Mountains, China and also discover the presence of a population of S. vandenburghi in the same region. Morphological characteristics and molecular phylogenetic analyses indicate that the new species is similar to S. vandenburghi, but clearly distinct from it and other congeners. The new species has the following characteristics: (1) slender body, small size, snout-vent length 24.47–40.60 mm; (2) supraciliaries 6 or 7; (3) midbody scale row counts 28–31; (4) dorsal scales smooth and slightly enlarged, paravertebral scale row counts 55–68, ventral scale row counts 55–64; (5) upper edge of lateral longitudinal stripes relatively wavy, lower edge irregular, covering 2–2.5 scale rows on the trunk; (6) black dorsolateral stripes from posterior corner of eye to lateral side of tail, six rows of dorsal scales in middle; (7) supralabials 7, infralabials 6 or 7; (8) tympanum diameters significantly smaller than palpebral disc diameters; (9) 9–12 enlarged lamellae beneath finger IV and 14–17 beneath toe IV; (10) 3–4 pairs of nuchal scales; (11) when the limbs are pressed down, toes and fingers touch or overlap. Phylogenetic analyses indicate that the population from the Dabie Mountains in Anhui Province, China, represents a new species, with a 3% uncorrected genetic distance in 16S rRNA from its closest relative (S. vandenburghi). This discovery brings the total number of Scincella species in China to 19, identifying the known distribution of the genus. We have made preliminary progress in clarifying the relationship between S. vandenburghi and S. modesta; however, the polyphyletic issues surrounding S. modesta warrant further investigation in future research. Additionally, the distribution patterns and divergence times of the two Scincella species in the Dabie Mountains require further study to gain a more comprehensive understanding.

Diagnosis. Scincella dabieshanensis sp. nov. can be diagnosed from other Scincella species by the following unique combination of characters: (1) slender body, small size, snout-vent length 24.47–40.60 mm; (2) supraciliaries 6 or 7; (3) midbody scale row counts 28–31; (4) dorsal scales smooth and slightly enlarged, paravertebral scale row counts 55–68, ventral scale row counts 55–64; (5) upper edge of lateral longitudinal stripes relatively wavy, lower edge irregular, covering 2–2.5 scale rows on the trunk; (6) black dorsolateral stripes from posterior corner of eye to lateral side of tail, six rows of dorsal scales in middle; (7) supralabials 7, infralabials 6 or 7; (8) tympanum diameters significantly smaller than palpebral disc diameters; (9) 9–12 enlarged lamellae beneath finger IV and 14–17 beneath toe IV; (10) 3–4 pairs of nuchal scales; (11) when the limbs are pressed down, toes and fingers touch or overlap.

Etymology. The specific epithet dabieshanensis is derived from the type locality, the Dabie Mountains, located at the boundary of Anhui, Henan and Hubei Provinces. We propose the English name of “Dabie Mountains Ground Skink” and the Chinese common name is “Dà Bié Shān Huá Xī (大别山滑蜥)”.
