Akysidae with the following
combination of characters: snout extending well anterior of margin
of lower jaw, rendering mouth subterminal; narial openings relatively
large and closely set; and caudal fin deeply forked. Remarks:
This genus corresponds to the “pseudobagarius group”
of species of the genus Akysis that was first recognized
by Ng & Kottelat (1998). Dorsal soft rays (total): 6 - 6; Anal
soft rays: 6 – 8; Vertebrae: 31 – 34. Distinguished
from all its congeners by the following combination of characters:
light-yellow snout with a sharp, contrasted edge discrete line demarcation;
presence of 4-6 small serrae on the posterior edge of pectoral spine;
head width 20.3-25.5% SL; depth of caudal peduncle 5.5-7.1% SL;
length of anal-fin base 9.7-16.6% SL; length of nasal
barbel 16-38% HL; 5 branchiostegal rays; and caudal fin deeply emarginate.
A look-a-Like, Akysis pulvinatus, is thought to mimic this
catfish in the same habitat, so called a Müllerian mimic. |
