Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 8; Rückenflossenweichstrahlen (insgesamt) : 9. This species is distinguished by the following characters: D VIII,9; pectoral fins 15-16; gill rakers 7-8 + 19-22 = 26-29; lateral line scales 35-38; body depth at first dorsal fin origin 22-26% SL and at anus 18-22% SL; caudal-peduncle depth 8.3-9.3% SL; maximum head depth 20-24% SL; head depth through eye 17-19% SL; head length 30-34%SL; orbit length 7.7-11% SL; upper jaw length 12-14% SL; barbel length 18-24% SL; caudal-fin length 27-31% SL; anal-fin height 13-16% SL; pelvic-fin length 20-24% SL; pectoral-fin length 21-24% SL; first dorsal-fin height 19-23% SL; second dorsal-fin height 15-16% SL; 7-10 total bars on caudal fin, 3-6 pale brown bars proximally to dark brown or black at distal margin on upper caudal-fin lobe, 3-4 brown bars on lower lobe, becoming darker distally, the last 2 completely dark brown or black with bars slightly increasing in width distally, small bar on tip; width of largest lower caudal-fin lobe bar and/or space between distal-most bars less than orbit; lateral body stripes absent; tip of first dorsal-fin dark; barbels white; body white ventrally and rose-red laterally, becoming dorsally darker with some gold iridescence along dorsal flanks and a darkened saddle behind second dorsal fin; body uniformly brown or little darker dorsally, bars and black first dorsal-fin tip retained in preserved fish (Ref. 83903).
