Abstract
A new species of the genus Oreolalax Myers & Leviton, 1962 is described from Sichuan Province, southwest China. Molecular phylogenetic analyses based on mitochondrial gene sequences clustered the new species as an independent clade nested with O. rugosus, O. liangbeiensis, and O. major. The new species could be distinguished from its congeners by a combination of the following characters: body size moderate (39.8–52.8 mm in male); head broad; tympanum absent; interorbital region with dark triangular pattern; 1/3 toes webbed, with broad lateral fringes, belly smooth, brown yellow or medium yellow scattered variable brown spots; skin on dorsum relatively rough with fine tiny and large warts granules; middle pectoral glands are evident in males; flanks with dark-brown warts granules; upper surface of limbs with dark bars; and iris orange above and creamy-white below. The new species inhabits subtropical alpine scrub and swamp.

[Ichthyology • 2023] Lasiancistrus wiwa • Phylogenetic Revision of Whisker-cheeked Suckermouth Catfishes (Siluriformes: Loricariidae: Lasiancistrus) from east of the Andes: Five Species where once there were Two

Abstract
We integrated large sample sizes, morphometric and molecular data, and phylogenetic and species delimitation analyses to test the 17-year-old hypothesis that only two species of whisker-cheeked suckermouth catfishes (genus Lasiancistrus) occur in river drainages west of the Andes Mountains. Our results reject this hypothesis, demonstrating that, in addition to the previously recognized Lasiancistrus guacharote from Lake Maracaibo, a Lasiancistrus clade from west of the Sierra de Perijá contains at least four allopatric, genetically differentiated and morphologically distinct lineages. One of these lineages had no previous name associated with it and is described here as the new species Lasiancistrus wiwa. Phylogenetic relationships and geographical distributions of all five trans-Andean lineages are concordant with watershed boundaries and major mountain ranges that form these boundaries, with the following five freshwater basins or regions each containing a single species: Lake Maracaibo (L. guacharote), Rancheria River basin (L. wiwa), Upper and Middle Magdalena River and lower Cauca River basins (Lasiancistrus volcanensis), Upper Cauca River basin (Lasiancistrus caucanus) and Pacific Coastal watersheds between central Colombia and central Panama (Lasiancistrus mayoloi). Evolutionary relationships among these lineages suggest that Andean uplift-mediated vicariance contributed significantly to the cladogenesis and allopatric distributions of these fishes.

Meriania judithiae  

in Jiménez, Iturralde, Mendoza, Ocupa-Horna et Garzon-Suarez, 2024.
 
Abstract
Meriania judithiae, a new species from the southeast of Morona Santiago in Ecuador, is described and illustrated. With this new addition, the number of species of the genus increases to 33 in this country. Meriania judithiae has leaves with a attenuate base extending down the petiole as wings, multiflorous inflorescences with sub-umbellate paraclades, pink-orange campanulate flowers, the calyx with conical projections, and isomorphic stamens with connectives prolonged below the thecae. It is compared with M. cuneifolia, its most similar species which shares the distant supra-basal venation and gradually narrowing base of the leaves. In addition, the taxonomic similarities of the new entity are discussed and information about its distribution, habitat, and conservation status is provided.

Diagnosis. This species is most similar to Meriania cuneifolia subsp. cuneifolia but differs by the sparse furfuraceous indumentum (vs. hirsute), the much shorter petioles 0.3–1.0 cm long (vs. 2.0–3.0 cm long), the leaf blades with attenuate bases extending into the petiole as wings (vs. long-cuneate), the shorter calyx lobes 0.5–1.3 mm long (vs. 8.5 mm long) each with a conical projection that does not surpass the apex of the lobe (vs. distinct claw-shaped projections extending further the lobes), and the isomorphic stamens (vs. dimorphic).  

Etymology:—The new species is named after Judith A. Steck, mother of David R. Goucher who has been actively supporting botanical research, environmental education and conservation in the south of Morona Santiago province, Ecuador.

[Entomology • 2023] Cephonodes sanshaensis • The Genus Cephonodes (Lepidoptera: Sphingidae) from Xisha islands, Hainan Province, China, with Description of A New Species


  Cephonodes sanshaensis  Deng & Huang, 

in Deng, M. Wang, Tang, Cai, Ma, X. Wang et Huang, 2023.

Abstract
A new species, Cephonodes sanshaensis Deng & Huang, sp. nov. is described from Xisha islands near Sansha City, China. Photographs of the adults and their genitalia are provided. The new species is similar to C. hylas (Linnaeus, 1771) and C. picus (Cramer, 1777) but can be easily distinguished by characters in the male genitalia: the right lobe of the uncus is hook-shaped with distinctly acute apex, the left valva is long and narrow with a truncate apex, and the right valva is broad and knife-shaped. Molecular analysis based on cytochrome c oxidase I gene barcode sequences is used to infer the phylogenetic position of the new species within the genus Cephonodes. An updated key and checklist to the worldwide species of the genus Cephonodes are also provided.

Diagnosis. Cephonodes sanshaensis sp. nov. is significantly different from Cephonodes hylas, the type species of the genus Cephonodes, with an apical claw on foretibia. C. sanshaensis is similar to C. kingii but is immediately distinguishable by a shorter apical brown area. Among the known species Cephonodes, this new species is most similar to C. picus (Cramer, 1777) but can be distinguished by the following characters: i) the right lobe of the uncus is hook-shaped with distinctly acute apex, whereas in C. picus, it is slender and rod-like; ii) the left valva is long and narrow with a truncate apex, whereas in C. picus, it is broad and somewhat dilated apically; iii) the costa of the right valva is straight, but in C. picus, it is slightly concave; and iv) the papillae anales of female genitalia is small and suborbicular, but in C. picus, it is with a sharp tip.

[Mammalogy • 2024] Rhinolophus webalai • Systematics of the Rhinolophus landeri complex (Chiroptera: Rhinolophidae), with Evidence for 3 Additional Afrotropical Bat Species

Webala’s Horseshoe Bat  ||  DOI: 10.1093/jmammal/gyae085

Abstract
Roughly a third of all horseshoe bat species (Rhinolophidae: Rhinolophus) are found in Africa, where a recent continent-wide genetic survey suggested the presence of both undescribed and apparently invalid species. Here, we focus on the R. landeri species complex and the recent elevation of R. lobatus Peters, 1852, to species rank. That action created ambiguity in the taxonomy of East African members of the group—are both R. landeri Martin, 1838, and R. lobatus sympatric in East Africa or is another, unnamed species present there? Here, we refine genetic, morphological, and behavioral characterizations of R. landeri and its erstwhile synonyms with samples from the vicinity of their type localities. The distribution of R. landeri appears to be limited to Central and West Africa; existing genetic records attributed to this species from Mali clearly represent another taxon. We marshal genetic evidence for the species-level distinction of R. dobsoni Thomas, 1904, from Sudan, which was previously considered a synonym of R. landeri. We reject R. axillaris J. A. Allen, 1917, as a synonym of the R. landeri complex, provisionally regarding it as a valid member of the landeri species group. Finally, we demonstrate that East Africa is home to a fourth species of the landeri complex that is named herein. Final resolution of the systematics of this species complex awaits expanded characterizations (especially of genetics, vocalizations, and noseleaves) and studies of variation in regions of contact.

Webala’s Horseshoe Bat

Diagnosis: A small member of the R. landeri species complex with spade-shaped sella, acutely triangular connecting process, lancet with strongly concave tip, and the presence of rust-colored axillary tufts in a majority of adult males (Fig. 6). Middle lower premolar tiny, displaced labially and barely reaching the cingula of flanking premolars (Fig. 7). Echolocation call (Supplementary Data SD6) dominated by long constant-frequency signal flanked by brief initial and terminal frequency-modulated elements, the latter with a greater frequency span, making call bandwidth very broad. Peak frequency averages 109.7 kHz, end frequency 80.2 kHz, and bandwidth 30.2 kHz. Unlike other sampled members of the landeri complex, the fundamental (first) harmonic of the call is conspicuous.

Etymology: We are pleased to name the new species after one of Africa’s foremost bat biologists, Dr. Paul Waswa Webala, in recognition of his important contributions as a field biologist, conservation scientist, prolific author, and mentor to Africa’s next generation. We suggest Webala’s horseshoe bat as a common name for this species.

Abstract
A new species of the genus Liurana is described from Medog, Xizang, China, based on morphological and molecular data. Molecular phylogenetic analysis based on the mitochondrial gene COI indicated that this new species represented an independent evolutionary lineage. In addition, the uncorrected genetic distance between the new species and its closest congener species, L. alpina, was 9.6%–9.8% for COI. The new species, Liurana namchabarwa sp. nov. Yu, Lin, Wang, Jiang and Xie, could be distinguished from its congeners by following characters: (1) relatively large body size in this genus, SVL = 21.2–23.1 mm in adult males ( n = 3); (2) relatively narrow head (HL/HW = 100.5%–104.8% ( n = 3)); (3) digital disc not expanded; (4) relatively long hindlimbs, with tibiotarsal articulation reaching tip of snout when adpressed.

Liurana namchabarwa sp. nov. Yu, Lin, Wang, Jiang and Xie  

Diagnosis: 
Liurana namchabarwa sp. nov. is assigned to the genus Liurana by its phylogenetic position and the following morphological characters: (1) body size small (SVL 21.2–23.1 mm, n = 3); (2) large, oval tongue with notch and scattered small papillae; (3) interdigital webbing absent; (4) tarsal fold absent; (5) vomerine teeth absent; and (6) vocal sac and vocal sac openings absent.
Liurana namchabarwa sp. nov. can be distinguished from its congeners by a combination of the following morphological characters: (1) SVL 21.2–23.1 mm; (2) HL larger than HW; (3) tympanum distinct; (4) tibiotarsal articulation reaching tip of snout when adpressed; (5) metacarpal tubercles absent; and (6) not expanded digital disc.

Habitat of Liurana namchabarwa sp. nov. in Nibiri, photographed in June 2022.

Etymology: The specific epithet of the new species, “ namchabarwa” means “Namcha Barwa Mountain”, indicating that the habitat of this species is very close to the Namcha Barwa Mountain.
We suggest Namchabarwa Papilla-tongued Frog as its English common name and Nan Jia Ba Wa She Tu Wa (南迦巴瓦舌突蛙) as its Chinese common name.

[Paleontology • 2024] Makrokylindrus itoi • A beautifully preserved comma shrimp (Pancrustacea: Peracarida) from the Plio-Pleistocene of Japan and the fossil record of crown Cumacea


 Makrokylindrus itoi 
Luque & Gerken, 2024

 
Abstract
 Comma shrimp, or cumaceans, are diverse benthic crustaceans, yet they are one of the groups with the poorest fossil record, hindering our understanding of the evolution of the group in deep time. Here, we describe a new species of fossil comma shrimp, Makrokylindrus itoi sp. nov., from the Plio-Pleistocene of Japan. The singular fossil is exceptionally preserved, including details of the carapace, cuticle, and some appendages, and it represents the first known fossil of the family Diastylidae and only the fourth fossil crown group cumacean known to date. We suggest that the scarce and sparsely known fossil record of cumaceans likely reflects a lack of recognition due to their small size and unfamiliar anatomy, making fossil cumaceans easy to misidentify, be confused with crustacean larvae of unknown affinities, or be interpreted as fragments of other crustaceans (taxonomic bias), rather than a lack of fossilization potential (taphonomic bias).

  Makrokylindrus itoi sp. nov.

 Diagnosis: The carapace, pereon, and pleon were covered with small and large pits arranged in a scale-like pattern. The carapace bore a line of large pits that paralleled the ventral margin. The pseudorostral lobes were 0.5× the total carapace length. The telson was cylindrical, and it was at least 3× longer than pleonite 6 length, with the post-anal portion much shorter than the pre-anal.

 Etymology: The specific epithet honors the late Mr. Takashi Ito, an avid fossil collector and artist from Japan who discovered and collected the holotype, made it available for study, and donated it to the Yale Peabody Museum.

Abstract
In addition to the type locality (the summit of Aprada-tepui, Bolívar State of Venezuela), the distribution of the egg-brooding frog Stefania satelles was long thought to include several isolated tabletop mountain (tepui) summits surrounding the large Chimantá Massif in Bolívar State (hence the Latin name “satelles”). However, multilocus molecular phylogenetic analyses have revealed that this taxon includes several undescribed morphologically cryptic species, and that S. satelles should be restricted to its type locality. Two tepui-summit species confused under that name in the literature remain to be named, and the present paper aims at describing these populations previously referred to as Stefania sp. 3 and S. sp. 5. Stefania sp. 3 is only known from the small summit of Angasima-tepui, while S. sp. 5 is only reported from the small summit of Upuigma-tepui, both mountains being located south of the Chimantá Massif. These new, phylogenetically distinct species are described based on external morphology and osteology and in comparison to close relatives in the S. ginesi clade, which consists exclusively of tepui summit species. Both new species have highly restricted geographic ranges (less than 3 km2) and should be listed as Critically Endangered according to IUCN criteria.

Stefania imawari sp. nov.

Etymology. The specific epithet imawari is a noun used in apposition and refers to the malicious spirits that inhabit the tepuis, according to Pemón traditional beliefs (Arturo Berti, pers. comm.). The Pemón are indigenous people living in the southeast region of Venezuela, including the area surrounding the type locality.
