Dorsal spines (total):
1 - 1; Dorsal soft rays (total): 7 - 7; Anal spines: 0; Anal
soft rays: 7 – 10; Vertebrae: 45 – 47. A relatively
small and narrow mouth opening; extremely reduced oral dentition;
relatively short dorsal-fin spine with 15 or fewer serrae; both
inner and outer mandibular barbels crenulated; a slender body
(body depth at anus 15.1-18.4% SL; depth of caudal peduncle
6.7-8.3% SL); a short adipose fin base (length 43.3-48.9% SL);
the genital papilla in males touching the base of the first
anal-fin ray; a uniformly brown body without both a pale midlateral
stripe and pale blotches on the sides of the body. Remarks:
Bagrichthys obscurus is described from drainages in Indochina.
It is morphologically similar to and has been previously identified
as B. macropterus, but can be differentiated from that
species in having a uniformly brown body without a pale midlateral
stripe and without pale blotches on the sides of the body, a
more slender body, a shorter adipose-fin base, and the genital
papilla in males meeting the base of the first anal-fin ray.
