The presence of more than three anal fin
spines is also characteristic of the Cichlidae and excludes identification as a labroid (Carpenter, 2001).
The testes and anal fin
were dissected and preserved in Bouin's fixative and 10% neutral-buffered formalin, respectively, then transferred to 70% ethanol.
Counts included: dorsal fin spines and rays, anal fin
spines and rays, pectoral fin rays, pelvic fin spines and rays, caudal fin rays, gill rakers on the first gill arch, vertebrae, scales in lateral line, scales above lateral line, and scales below lateral line.
The specimen had very dark mottled coloration, an anus closer to the edge of the suctorial disk than the origin of the anal fin
and a single row of teeth in the lower mandible.
On the blind side the tubercles occur at the bases of the longest dorsal and anal fin
rays but are absent anteriorly and posteriorly of those areas.
Ventrum cream to light brown, dorsal and caudal fin dark blue-black, anal fin
dark gray to dark blue-black, pelvic fin light with black tips, pectoral fins mostly brown-black, but distal half of unbranched rays white.

to the caudal end of the head.
Dark lateral stripe continuous with caudal-peduncle spot; caudal-peduncle spot rounded, and not extending onto middle caudal-fin rays; 15-17 pored lateral-line scales; six scales between lateral line and anal-fin origin; six scales between lateral line and pelvic-fin insertions; nine predorsal scales; ii,8,i dorsal-fin rays; anal fin
with 21-22 branched; pectoral-fins with twelve branched rays; males with bony hooks on anal and pelvic fins H.

Sex was identified visually using the elongated anal fin
