It resembles Microthrissa royauxi, which has fewer gillrakers but more anal finrays, 14-16 and 23-27 respectively (Ref. 188).
Description: Body depth 21.7-30.0% of standard length; head length 11.1-12.7% of standard length (Ref. 188, 93833). Premaxilla with 12-30 conical teeth directed inwards; 11-25 little conical teeth on maxillary (Ref. 47399). Dorsal fin origin closer to snout than caudal fin base, inserted behind pelvic fin base; dorsal fin with 12-15 fin rays; anal fin with 18-21 fin rays; ventral fin with 1 unbranched and 6 branched rays; pectoral fin with 10-13 fin rays (Ref. 47399, 93833). Cycloid scales; 37-43 on longitudinal line (Ref. 47399). First gill arch with 18-22 gillrakers on lower limb, 27-32 total gillrakers (Ref. 47399). Scutes present: 1-2 prepectoral scutes without ascending arms, 10 prepelvic scutes with ascending arms, 1 subpelvic scute without ascending arms, 7 postpelvic scutes with ascending arms; strongly keeled (Ref. 93833). Vertebrae 40-44 (Ref. 47399).
