Psilorhynchus pavimentatus Conway & Kottelat 2010

Shares with its most similar congeners Psilorhynchus amplicephalus, Psilorhynchus balitora and Psilorhynchus nepalensis a low number of rays in the upper caudal finlobe and in terms of general appearance. Diagnosed from these species and all other congeners by presence of sexually dimorphic pectoral fins, which are much longer in males than in females (vs. pectoral fins of both sexes equal in size or only slightly longer in males). Differs further from Psilorhynchus amplicephalus, Psilorhynchus balitora and Psilorhynchus nepalensis by its higher number of principal rays in the lower caudal-fin lobe (9 vs. 8 in Psilorhynchus amplicephalus and Psilorhynchus nepalensis, 7-8 in Psilorhynchus balitora), and from Psilorhynchus balitora by the absence (vs. presence) of scales from the midventral region between pectoral fins. Can be easily separated from three other congeners (Psilorhynchus breviminor, Psilorhynchus robustus, and the sympatric Psilorhynchus melissa) in Myanmar by having lower number of principal rays in the upper caudal-fin lobe (9 vs. 10) (Ref. 85100).Description: Dorsal fin with iii.9 rays; anal fin with ii.6 rays; pectoral fin with vi.9, vi.10 or v.11 rays; pelvic fin with ii.7 rays (Ref. 85100).

Dorsal soft rays (total): 12; Analsoft rays: 8; Vertebrae: 34

Collected together with Akysis vespertinus, Psilorhynchus melissa and other new fish species from the headwaters of Ann Chaung drainage in Myanmar (Ref. 85100).

Psilorhynchus pavimentatus is a freshwater ray-finned fish, from the headwaters of Ann Chaung drainage in Myanmar. This species reaches a length of 5.0 cm (2.0 in).
