The psychid genus Pharcidopsyche Saigusa et Sugimoto, gen. nov. and its type species, Pharcidopsyche novemplicata Saigusa et Sugimoto, sp. nov. (Lepidoptera, Psychidae) are described based on the adults, larvae and larval case from Sabah, Borneo. Pharcidopsychinae, subfam. nov. is established for the new genus. The adult and larval morphology, larval case and biology of the type species are described.

A new earthworm genus with two new species (Clitellata, Megascolecidae) from the Western Ghats mountain ranges of south-western peninsular India

S. PRASANTH NARAYANAN, A.P. THOMAS, J.M. JULKA — Tue, 28 Jan 2025 00:00:00 +1300

A new megascolecid earthworm genus, Aiyeriella Narayanan & Julka gen. nov., is established from the Western Ghats biodiversity hotspot of India, with two new species, namely, A. quadritheca Narayanan & Julka, sp. nov., and A. longiprostata Narayanan & Julka, sp. nov. Material of the new genus and species were collected from the three southernmost districts of Kerala state, in the south-western portion of peninsular India. The present new genus can be distinguished from other related Indomalayan megascolecid genera by the presence of combined male and prostatic pores paired in seminal grooves on segment 18, with a single well-developed oesophageal gizzard in segment 5, penial setae, calciferous glands, intestinal caeca, and typhlosole absent, meronephric throughout the body, 10–14 in transverse bands of micromeronephridia behind clitellum and prostates tubuloracemose, paired, elongated, and strap-shaped.

**A new species of catfish, Pterocryptis vorax (Actinopterygii: Siluridae), from northern Borneo**

HEOK HEE NG, RAFHIAH KAHAR, HEOK HUI TAN — Tue, 28 Jan 2025 00:00:00 +1300

This study describes Pterocryptis vorax, a new species of silurid catfish from the upper reaches of the Temburong River drainage in Brunei Darussalam, northern Borneo. Pterocryptis vorax is distinguished from congeners in having a unique combination of the following characters: rictal lobe ending at vertical posterior to posterior orbital margin, deep lower jaw with a more gently curved anteroventral margin, a color pattern of densely distributed dark brown patches on the flanks that coalesce to form a reticulate pattern, a dark vertical band at the caudal-fin base, 46–57 anal-fin rays and 48–49 vertebrae. Sexual dichromatism in Pterocryptis is also reported for the first time here.

**A new miniature Priocharax from the río Putumayo drainage, Amazonas State, Colombia (Teleostei: Characiformes: Characidae) with an unusual skin flap between pelvic fins**

Tue, 28 Jan 2025 00:00:00 +1300

The miniature fish genus Priocharax currently comprises nine valid species: P. ariel, P. britzi, P. conwayi, P. marupiara, P. nanus, P. phasma, P. pygmaeus, P. toledopizae and P. varii. Except for P. ariel and P. pygmaeus, all remaining species are endemic to Brazil. Priocharax is characterized by several paedomorphic features such as reductions in the laterosensory system, number of fin rays, and ossification of parts of the skull. The most striking reductive character of Priocharax is the larval rayless pectoral fin in which most of its endoskeletal part is absent. A new species of Priocharax is described herein from the río Putumayo drainage, Departamento Amazonas, Colombia. The new species is distinguished from all other congeners by a unique round flap of skin between contralateral pelvic fins.

Maintaining taxonomic accuracy in genetic databases: A duty for taxonomists—Reanalysis of the DNA sequences from Mercan et al. (2024) on the genus Potamothrix (Annelida, Clitellata) in Turkish lakes

RÉGIS VIVIEN, PATRICK MARTIN — Tue, 28 Jan 2025 00:00:00 +1300

Public DNA sequence databases such as GenBank are widely used for identification of organisms in ecological and taxonomic studies. It is important that these public databases contain as few mistakes as possible and that any errors detected in these databases are reported. Here, we reanalyzed the COI sequences of Mercan et al. (2024) and showed that they were mistakenly considered by these authors as belonging to different populations (haplotypes) within the species Potamothrix hammoniensis (Tubificinae). We found that they corresponded to four distinct Tubificinae lineages (species), Pothamothrix alatus paravanicus, Potamothrix bavaricus, Tubifex sp. and Potamothrix sp. Despite these identification errors, the data from Mercan et al. (2024) remain interesting as they provide new information on the diversity of the genus Potamothrix in Turkey. Prompt measures must be taken to correct these errors and prevent them from being detrimental to future studies.

**Synopsis of Barra Jordan, 1904 (Coleoptera: Anthribidae) with description of a new species from Brazil with an updated key to the genus**

Tue, 28 Jan 2025 00:00:00 +1300

Barra tocantinensis Vilhena, Lopes & Mermudes sp. nov. (Anthribinae: Piesocorynini) is described from Serra do Lajeado Ecological Reserve (Fazenda Céu), a threatened biome in central-western Brazil. A key to the all known species of Barra is presented. New data on the distribution of the genus are provided.

**First record of the genus Sundagrapha Holloway, 1982 (Lepidoptera, Geometridae, Ennominae, Cassymini) from China, with description of a new species**

BO LIU, WEI YAN — Tue, 28 Jan 2025 00:00:00 +1300

The genus Sundagrapha Holloway, 1982 is reported from China for the first time. A new species, Sundagrapha recta sp. nov., is described from Hainan Province. Adults of both sexes and their genitalia are illustrated and compared with those of closely related species. Additionally, a comprehensive identification key for all currently known species of Sundagrapha is provided.
