Dorsal-fin rays II,6 (n=3); anal-fin rays 19-22 (n=3); pectoral-fin rays I,9 (n=3); pelvic-fin rays 6, 1 unbranched and 5 branched (n=3); principal caudal rays variable, as with congenerics; gill rakers on first pharyngeal arch 13 (n=3), 3 on epibranchial. Body shape and form shown in Fig. 3. Head very elongate; distance between anterior and posterior nostrils longer than other congeners. Head length variable, 3.55-4.25 times gape width (n=3, range 3.55-4.25, mean 3.90); interorbital distance 3 times or less than eye diameter (n=3, range 2.37-3.07, mean 2.79); anal fin length 2 times or greater than adipose fin length (n=3, range 2.12-2.64, mean 2.36); premaxillary tooth patch width equal to its length (n=3, range 1.03-1.09, mean 1.06). Eyes lateral, barely visible from ventral view, if at all. Inner mental barbels just anterior to or even with gular apex (Fig. 3C). Maxillary barbels extend to pelvic fins.</paragraph>
