Psilorhynchus pavimentatus
Conway & Kottelat, 2010
Two new species of Torrent Minnow (Ostariophysi: Psilorhynchidae) from western Myanmar.ABSTRACT.
Two species of Psilorhynchus from the headwaters of the Ann Chaung drainage, central Rakhine State, Myanmar, are described. Psilorhynchus melissa, new species, differs from all its congeners by a unique colour pattern, including a dark band running along the distal edge of the dorsal fin and an intense scattering of dark melanophores along the anterior edge of the paired fins. Psilorhynchus pavimentatus, new species, differs from all its congeners by exhibiting sexual dimorphism of its pectoral fins, and from all similar looking species by a combination of characters, including the absence of scales from the midventral region between pectoral fins, a higher number of principal rays in the lower caudal-fin lobe (9 vs. 7-8) and aspects of its colour pattern, including the absence of vertical bars on the caudal fin.
