Redescription of Psilorhynchus rowleyi Hora and Misra 1941 (Cypriniformes: Psilorhynchidae)

Abstract

Psilorhynchus rowleyi Hora and Misra 1941 known from the Chindwin–Irrawaddy drainage, formerly treated as a subspecies of the Ganga–Brahmaputra drainage species, Psilorhynchus homaloptera Hora and Mukerji 1935, is redescribed here based on newly collected materials and two syntypes in the Zoological Survey of India. It differs from the latter in having a larger eye (21.7–31.5 % head length vs. 13.4–19.4), a greater number of principal rays in the lower lobe of the caudal fin (9 vs. 8), a longer (vs. shorter) upper lobe of the caudal fin, fewer unbranched pectoral-fin rays (vii vs. viii), a higher number of predorsal scales (14–15 vs. 12–13), a lower number of transverse scales below the lateral line (2 vs. 2½), a narrower caudal peduncle (44.0–52.9 % caudal-peduncle length vs. 57.9–76.2) and a dome-shaped (vs. slightly pointed) rostral cap. The lectotype of P. rowleyi was also designated.
