Vertebrae: 39 - 40. Can be diagnosed from other species of Batasio by the combination of the following characters: dorsal to adipose distance 1.7-4.1% SL; snout length 39.2-45.5% head length; eye diameter 24.6-29.8% head length; gill rakers on the first branchial arch 4-5; pectoral spine length 14.6-17.6% standard length; adipose-fin base length 31.0-34.9% standard length; post-adipose distance 10.6-13.7% standard length; branched pectoral fin rays 9-10; 39-40 vertebrae; and body with a dark-brown oblique predorsal bar on a uniform light-brown background (Ref. 87063).
