Short description
Identification keys | Morphology | Morphometrics
This species is distinguished from its congeners in Sundaland except for G. amnestus, G. major, G. plectilis<.i> in having (vs. lacking) anteromedial striae on the thoracic adhesive apparatus; differs from G. amnestus in having (vs. lacking) a dark vertical bar at the base of the caudal fin in the shape of an irregular cross; differs from G. major in having a deeper caudal peduncle, 10.3-10.9% SL (vs. 7.7-10.1) and with a faint, pale band around the caudal peduncle (vs. absent); differs from G. plectilis in having non-prominent tubercles of uniform size (vs. with prominent, enlarged tubercles) along the flanks. It is further distinguished from Sundaic congeners by the following unique characters: premaxillary tooth band approximately half exposed when mouth is closed; eye diameter 8-9% HL; head length 27.2-30.2% SL and width 19.9-22.3% SL; predorsal length 35.8-40.0% SL; dorsal-fin spine length 16.0-17.3% SL; margin of dorsal fin concave; dorsal-to-adipose distance 18.6-21.2% SL; body depth at anus 17.8-19.7% SL; straight dorsoposterior margin of the adipose fin; post-adipose distance 16.2-17.5% SL; caudal peduncle depth is 2.0 times in body depth at dorsal-fin origin; no dark vertical bars at adipose-fin base and caudal-fin base and prominent pale midlateral stripe on the body (Ref. 128699).
