Taggstrålar i ryggfenan (totalt) : 8; Mjukstrålar i ryggfenan (totalt) : 10; Taggstrålar i analfenan: 7; Mjukstrålar i analfenan: 9; Ryggkotor: 23. Diagnosis: Pectoral rays 17-18. Scale rows above the lateral line 20-23. Gill rakers 6-7 + 17-18. Body depth 2.35-2.4 in SL; head length 4.1-4.4 in SL; snout length 2.4-2.6 in HL; longest dorsal spine 2.05-2.1 in HL. Dorsal profile of head from above front of eye to tip of recumbent dorsal spine concave. Caudal fin deeply emarginate, caudal concavity 1.35 in HL. The head and body light blue in life, with many small pale yellowish spots and very irregular narrow yellow bands, resulting in a fine reticular pattern for most of head and body (Ref. 55950).
Body shape (shape guide): short and / or deep.
Presumably feeding on zooplankton, but may only be opportunistic. Digestive tract of type specimen filled with benthic algae (Ref. 55950).
