Dibamus elephantinus
 Kliukin, Bragin, Thy, Gorin ... et Poyarkov, 2024 
 

Abstract
We describe a new species of blind skink of the genus Dibamus Duméril et Bibron, 1839 based on five specimens collected from Bokor National Park, Kampot Province, southern Cambodia. Dibamus elephantinus sp. n. can be distinguished from its congeners by the following combination of morphological characters: snout-vent length (SVL) up to 129.3 mm; tail length comprises 17–22% of SVL; rostral suture incomplete; nasal and labial sutures complete; single postocular; three scales at the posteromedial edge of first infralabial; two scales at the posterior edge of second infralabial; the medial sublabial scale enlarged; 19 midbody scale rows; 22 transverse scale rows just posterior to head; 17–19 transverse scale rows just anterior to vent; 178–202 ventral scales; 46–52 subcaudal scales; relative size of frontal to frontonasal (FSW/FNSW) 127–136%; relative size of interparietal to surrounding scales (IPW/NSW) 111–140%; in males hindlimbs longer than head length (HLL/HL 74–78%); the light colored band on the body may be present or absent. We provide an osteological description of the new species based on micro-CT data. Genetically and morphologically Dibamus elephantinus sp. n. is most closely related to D. dalaiensis inhabiting the western part of the Cardamom Mountains in Cambodia. The new species inhabits montane evergreen forests of Damrei Range (also known as Elephant Mountains) at elevations of ca. 1000 m a. s. l. Our study brings the number of species in the genus Dibamus to 27; Dibamus elephantinus sp. n. is the second species of Dibamus to be recorded from Cambodia.

[Entomology • 2024] Diaphanes uvaparanagama • A New Species of the Genus Diaphanes (Coleoptera: Lampyridae: Lampyrinae) from Sri Lanka


Diaphanes uvaparanagama Wijekoon, 

in Wijekoon et Wegiriya, 2024.
Asian Journal of Conservation Biology. 13(2); 

ABSTRACT 
A new species, Diaphanes uvaparanagama Wijekoon sp. nov., from a freshwater-associated habitat in Uva province, Intermediate Zone, Sri Lanka, is described using males and reliably associated larvae. Males of this species are distinguished by a transparent pronotum and elytra with bright red thoracic terga and mesocutellum, pale yellow abdominal ventrites, and medial restricted photogenic organs. The conical-shaped photogenic organs challenge the traditional generic diagnosis of Diaphanes using light organ morphology. 

Key words: Diaphanes, fireflies, new records, Sri Lanka

Diaphanes uvaparanagama (Male);
A Pronotum (dorsal). B. Elytra (dorsal). C. Head & Antennae. D Thorax & Legs; E. Abdomen (ventrites I-VIII). G. Light organ in ventrite VII & VII. (Scale bar = 1mm) (Note: natural colors are faded in alcohol specimens)

Family: Lampyridae Rafinesque, 1815 
Subfamily: Lampyrinae Rafinesque, 1815 
Genus: Diaphanes Motschulsky, 1853

Diaphanes uvaparanagama Wijekoon sp. nov. 

Diagnosis: Male: 10–11 mm long, distinguished from other recorded Diaphanes by the transparent pronotum and elytra with vivid red thoracic terga and mesocutellum, distinctly pale yellow abdominal ventrites (I - VIII), black legs except the pale yellow femora, LO in both V6 and V7 are median restricted, conical-shaped and milky white (Figs. 2 - 5) 
Larvae: 28.0–30.0 mm long, black dorsum with distinct white vertical spotted lines, pale yellow spots on posterior margin of each segment and outer margin of entire body, mid sagittal line clear, body elongated rather wide, first abdominal segment less longer than others (Figure 6). 

Etymology: This species is named for the area “Uvaparanagama,” where the first specimen was found. This area is located in Welimada, Uva Province, Sri Lanka. We use the name Uvaparanagama as a noun in apposition to preserve the original language.

[Herpetology • 2024] Oligodon zhangfujii • A New Species of Kukri Snake Genus Oligodon Fitzinger, 1826 (Serpentes: Colubridae) from Xizang, China


 Oligodon zhangfujii 
 Jiang, Wu, Huang, Ren, Gao, Lyu & L, 2024  


Abstract
A new species of the Kukri snake genus Oligodon is described from Mêdog County in the eastern Himalayas of China. The species, named Oligodon zhangfujii sp. nov., can be distinguished from all known congeners by a combination of the following morphological characteristics: (1) 17-17-15 dorsal scale rows; (2) six supralabials, third and fourth entering orbit; (3) one loreal present; (4) seven infralabials, first to fourth in contact with anterior chin shields; (5) 173 ventral scales and 47 pairs of subcaudal scales; (6) cloacal plate divided; (7) hemipenis single, shallowly bilobed, with large calcareous spines and a calyx area, sulcus spermaticus single; and (8) eight maxillary teeth. Phylogenetic analyses based on two mitochondrial genes revealed that this species occupies an independent phylogenetic position, distinct from the eight recognized species groups within the genus, and represents a sister taxon to the clade comprising the O. theobaldi and O. cinereus groups. The description is based on a single road-killed individual. As such, ecological data for the species remain sparse, underscoring the need for additional field surveys across the eastern Himalayan region.

[Crustacea • 2023] Diploexochus spinatus & D. obscurus • Cave-dwellers Diploexochus (Isopoda, Armadillidae): New Species and New Records of the Genus from Brazil

 
Diploexochus spinatus
Cardoso, Bastos-Pereira & Ferreira, 2023


Abstract
Two new species of Diploexochus are described. Diploexochus spinatus sp. nov. from Lapa do Honorato cave, located in the municipality of Iuiu, and Diploexochus obscurus sp. nov. from Água Escura I cave, located in the municipality of Carinhanha, both in the southwest of Bahia State, northeastern Brazil. Both species are likely to occur in caves due to anthropogenic impacts in the surrounding area (such as deforestation) and/or looking for the stable microclimatic conditions found in the subterranean realm. Additionally, D. echinatus is recorded in a cave in the municipality of Rurópolis, Pará State, northern Brazil. These represent the first records of the genus for subterranean environments.

Moema juanderibaensis
 Drawert, 2022 

 
Abstract
Moema, a genus of the Rivulidae family, currently comprises 20 valid species. Most of these species inhabit temporary pools in the Amazon basin and only one species is found in the upper Paraguay basin. A new member of this genus from the upper Río Madeira drainage is here described. Males of the new species differ from all congeners by the combination of a color pattern consisting of oblique, sometimes chevron-like, irregular rows of red and light blue double-dots on body; dark yellowish to golden pectoral fins with no visible markings; and a stripe pattern on the ventral section of caudal fin with a very narrow black marginal line, intermittent or even absent. The existence of infrageneric species groups within Moema, the geographic distribution and taxonomic aspects of the species present in the Ríos Mamoré and Iténez/Guaporé rivers drainages, and the observation of intraspecific aggression between males and amphibious lifestyle in the new species are discussed.

Moema juanderibaensis, new species

Diagnosis. Moema juanderibaensis differs from congeners by a unique combination of the following characters on males: pattern of oblique, sometimes chevron-like, irregular rows of red and light blue double-dots on flanks; dark yellowish to golden pectoral fin with no visible markings (dots or spots); and ventral part of caudal-fin stripe pattern with very narrow black marginal line, intermittent or even absent (vs. never in this combination). The new species is distinguished from Moema apurinan, M. beucheyi, M. funkneri, M. hellneri, M. heterostigma, M. nudifrontata, M. pepotei, M. piriana, M. portugali, M. quiii, M. schleseri, and M. staecki by the oblique arrangement of red and light blue double-dots on flanks (vs. flank color pattern arranged in horizontal lines or rows of dots). It differs from M. manuensis, M. obliqua, M. peruensis, M. rubrocaudata, M. schleseri, and M. wischmanni by the presence of red dots on flanks mostly arranged in oblique, sometimes chevron-like, rows (vs. absence of dots, or arranged in vertical rows or randomly distributed). It is distinguishable from M. boticarioi, M. kenwoodi, and M. obliqua by the absence of dots, spots or any other markings on pectoral fins of males (vs. presence of dark reddish-brown dots, few dark green dots or longitudinally elongated dark brown spots); from M. claudiae by the absence of black humeral blotch in males (vs. presence); and from M. schleseri by the ground color of pectoral fins (brown-yellowish to golden vs. hyaline) and color pattern of ventral section of caudal fin (thin black marginal line, sometimes intermittent and inconspicuous or even absent, and broad deep orange to red stripe vs. ventralmost black stripe broad, and orange stripe with dark red dots). Additionally, it is also distinguished from M. boticarioi by the absence of brown dots or other marks on dorsum (vs. dorsum with brown dots).

Etymology. Named juanderibaensis in reference to the name of the ranch “Juan Deriba” where the type locality is situated. An adjective.

Resumen: Moema, un género de la familia Rivulidae, actualmente comprende 20 especies válidas. La mayoría de estas especies habitan en charcos temporales de la cuenca amazónica y solo una especie se encuentra en la cuenca alta del Río Paraguay. Un nuevo miembro de este género de la cuenca alta del Río Madeira es descrito aquí. Los machos de la especie nueva se diferencian de todos los congéneres por la combinación de un patrón de color de filas irregulares oblicuas, a veces en forma de chevrón, de puntos dobles rojos y azul claro en el cuerpo; aletas pectorales de color amarillento oscuro a dorado sin marcas visibles; y un patrón de rayas en la sección ventral de la aleta caudal con una línea marginal negra muy estrecha, intermitente o incluso ausente. Se discute la existencia de grupos infragenéricos de especies dentro de Moema, la distribución geográfica y aspectos taxonómicos de las especies presentes en el drenaje de los Ríos Mamoré e Iténez/Guaporé, y la observación de agresión intraespecífica entre machos y estilo de vida anfibio en la nueva especie.

Abstract
Snake-eyed, or ablepharine skinks, are common residents of the highest mountain ranges on Earth, including the Himalayas, the Tibetan Plateau, Karakoram, Pamir, and Tian Shan, colloquially known as the Roof of the World. Historically, these skinks were alternatively assigned to the genera Scincella, Ablepharus, Asymblepharus, and Himalblepharus, but recent revisions proposed to group them in only two genera, namely Protoblepharus (the eastern Himalayan taxa) and Ablepharus (all other taxa). The taxonomy of this group yet remains in a state of flux due to the limited informativeness of available phylogenies (often with little material from the Himalayan region), discrepancies in morphological patterns of variation, and the potentially high yet unconsidered degree of diversity of the group. To shed some light, we assess the mitochondrial diversity and evolution of Himalayan snake-eyed skinks based on >200 individuals sampled across Pakistan, India, Nepal, and China, representing nine out of ten Himalaya currently recognized species. Phylogenetic relationships were inferred from 2998 bp of mitochondrial sequences (12S, 16S, ND2, cyt b). Our analyses reveal a remarkably high cryptic diversity, including 14 to 16 species-level lineages within Ablepharus and four species-level lineages within Protoblepharus, which would substantially increase the number of species by at least twofold. This hidden diversity highlights the Himalayas as a center of phylogeographic diversification and endemism, likely shaped by geological and climatic factors associated with orogenesis, which now houses over half of the ablepharine skink species.
