Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 1; Rückenflossenweichstrahlen (insgesamt) : 6; Afterflossenweichstrahlen: 7 - 10; Wirbelzahl: 32 - 35. This species is distinguished from all Sundaic congeners by the following characters: absence (vs. presence) of a medial pit in the thoracic adhesive apparatus and with (vs. without) prominent dark longitudinal stripes running through each caudal-fin lobe; differs from G. platypogon, the only congener known from Java, in having a straight (vs. convex) dorsoposterior margin of the adipose fin, a more slender caudal peduncle 6.6-8.3% SL (vs. 8.0-11.4), a longer caudal fin 26.5-30.4% SL (vs. 20.1-27.0) with narrower lobes, and with caudal peduncle depth 2.1-2.4 times in body depth at anus (vs. 1.6-1.9); differs with the other Sundaic congeners by having premaxillary tooth band approximately half exposed when mouth is closed. eye diameter 7-10% HL, interorbital distance 28-33% HL, head length 23.6-29.3% SL, no anteromedial striae in thoracic adhesive apparatus, pectoral-fin spine length 16.8-19.8% SL, predorsal length 36.7-40.0% SL, posterior margin of dorsal-fin spine smooth; margin of dorsal fin concave, dorsal-to-adipose distance 16.9-20.4% SL, dorsoposterior margin of adipose fin straight, prepelvic length 47.9-52.4% SL, body depth at anus 14.2-17.7% SL, post-adipose distance 17.0-19.6% SL. Colouration: almost uniform body with diffuse pale patches and lacking (vs. having in other congeners) dark vertical bars at the adipose-fin base and the base of the caudal fin (Ref. 128699).
Occurs in fast-flowing streams with a substrate of gravel and rocks. This species is found syntopically with G. platypogon (Ref. 128699).
