[[ Genus Erethistoides  ZBK  ]]

Members of the genus Erethistoides  ZBK  are small erethistid catfishes traditionally diagnosed by a strongly depressed head and body and the presence of diverging serrations (antrorse on the distal half and retrorse on the proximal half) on the anterior edge of the pectoral spine. The genus, known from the sub-Himalayan region of the Indian subcontinent, currently includes two nominal species: E. montana Hora  ZBK  , 1950 and E. pipri (Hora  ZBK  , 1950).

During a recent ichthyological survey of the northern Bengal region in India, specimens of Erethistoides  ZBK  were obtained, which upon further study, proved to be an undescribed species. The species is described here as Erethistoides sicula  ZBK  , new species. It was also found that the traditional diagnosis of Erethistoides  ZBK  is inadequate due to variation in the morphology of the pectoral-spine serrations. Here, four new synapomorphies diagnosing Erethistoides  ZBK  are identified and briefly discussed.
