توصيف مختصر كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري

خارهاي باله پشتي (کل) : 0; شعاع نرم باله پشتي (کل) : 12 - 15; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 18 - 21; مهره ها: 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 fin ray, 11-12 pre-pelvic and 6-8 post-pelvic scutes; snout pointed; lower jaw not or slightly projecting, included in upper when mouth closed, with small teeth limited to anterior part; pre-maxilla with 12-30 small conical teeth directed inwards; maxilla blade slender, more than 3 times as long as deep, upper edge with a ridge flared outward; posterior supra-maxilla small, spatulate, shaft as long as blade; lower gillrakers 18-22 (Ref. 188, 47399, 93833). Also characterized by 37-43 scales in a longitudinal series and anal fin with 18-21 rays (Ref. 47399). It resembles Microthrissa royauxi, which has fewer gillrakers but more anal fin rays, 14-17 and 23-27 respectively (Ref. 188). It is distinguished from Microthrissa whiteheadi by a lower number of teeth on the pre-maxilla, 12-30 vs. 32-40 in M. whiteheadi; and additionally by a higher number of lower gillrakers, 18-22 vs. 14-18, a lower number of anal fin rays, 18-21 vs. 20-25, and a lower number of pre-pelvic scutes, 11-12 vs. 13-16 (Ref. 46514, 47399).
