Litoria hastula  Oliver, Iskandar & Richards, 2023   DOI: 10.3897/vz.73.e91111 photographs by S.J. Richards. Abstract The mountains of New Guinea are home to species-rich but poorly understood communities of stream or torrent-breeding pelodryadid treefrogs. Here we describe a new species of moderately sized torrent-breeding Litoria from the mountains of Papua Province, Indonesia. The new species is most similar to Litoria dorsivena but differs from that species in aspects of body size, skin texture and especially the shape of the snout. Based on recent collecti ..read more

Mammillaria morentiniana  Gonz.-Zam., D. Aquino, J. Mohl & Dan. Sánchez, in González-Zamora, Aquino, Mohl & Sánchez, 2022. DOI: 10.3372/wi.52.52305  Abstract   We describe a new endemic densely spined Mammillaria from San Luis Potosí, Mexico. The new species, named M. morentiniana, is distinctive by the presence of a globose to shortly cylindric stem with several glabrous, reddish central spines, radial spines that protrude from the plant like white needle-bristles, and small flowers with pale yellow, lanceolate tepals. We compare it with simi ..read more

[Paleontology • 2023] Funcusvermis gilmorei • Triassic Stem Caecilian (Lissamphibia: Gymnophionomorpha) supports dissorophoid Origin of Living Amphibians

Funcusvermis gilmorei Kligman, Gee, Marsh, Nesbitt, Smith, Parker & Stocker, 2023   DOI: 10.1038/s41586-022-05646-5 Abstract Living amphibians (Lissamphibia) include frogs and salamanders (Batrachia) and the limbless worm-like caecilians (Gymnophiona). The estimated Palaeozoic era gymnophionan–batrachian molecular divergence suggests a major gap in the record of crown lissamphibians prior to their earliest fossil occurrences in the Triassic period. Recent studies find a monophyletic Batrachia within dissorophoid temnospondyls, but the absence of pre-Jurassic pe ..read more

Horaglanis populi Raghavan, Sundar, Arjun, Britz & Dahanukar, 2023   DOI: 10.3897/vz.73.e98367   twitter.com/LabRajeev  Abstract The lateritic aquifers of the southern Indian state of Kerala harbour a unique assemblage of enigmatic stygobitic fishes which are encountered very rarely, only when they surface during the digging and cleaning of homestead wells. Here, we focus on one of the most unusual members of this group, the catfish Horaglanis, a genus of rarely-collected, tiny, blind, pigment less, and strictly aquifer-residing species.
