Short description Morfologia | Morfometria

Spine dorsali (totale): 0; Raggi dorsali molli (totale): 12-15; Spine anali 0; Raggi anali molli: 18 - 21; Vertebre: 40 - 44. Diagnosis: Body moderately deep, its depth about 22-30% of standard length; scutes strongly keeled, 1 or 2 before base of first pectoral finray, 11-12 + 8; snout pointed; lower jaw not projecting, included in upper when mouth closed, with small teeth at symphysis; maxilla blade slender, more than 3 times as long as deep, upper edge with a ridge flared outward; second supra-maxilla small, shaft as long as spatulate blade; lower gillrakers 18-22; total anal finrays 18-21; scales in lateral series 37-40 (Ref. 188, 47399). It resembles Microthrissa royauxi, which has fewer gillrakers but more anal finrays, 14-16 and 23-27 respectively (Ref. 188).
