Morphology:

Dorsal
soft rays
(total): 21 - 25;
Anal
soft rays: 35 – 42. Body black, elongate and slender; depth 5-8% SL. Long, tapering protrusible snout. Slender barbel stem and two terminal bulbs. Barbel stem has little or no external pigment (Ref. 37039). Two terminal bulbs separated by a short interspace, less than half to 1.5 the length of distal bulb. Barbel length increasing to 70-91% SL in specimens 10.5-15 cm, apparently decreasing in large females (17.9-25.3 cm) to 46-51%. Terminal filament short (9% SL or less, slightly longer to 5 times longer than distal bulb) with 2 well-developed side branches arising just distal to bulb and often other branches along its length. All branches with prominent internal bulblets, some nearly the same diameter as branch, resulting in a series of swellings in many specimens. No melanophores in stem, between bulbs, or in filaments in specimens up to 15 cm SL; none between bulbs at any size. Middorsal paired spots under skin between occiput and dorsal-fin origin usually 8, sometimes 7 (Ref. 11333).
