Diagnosis |
Metzia parva is distinguished from all other congeners by the following characters: smaller body size, 48.3-57.7 mm SL (vs. 58.3-151.4 mm SL); lateral line complete, but interrupted in some specimens along ventral margin above anal-fin; anal fin with 12-14 branched rays (vs. 10-11 or 15-20); pectoral fin with 10 branched rays (vs. 11-16); pelvic fin with 6 branched rays (vs. 7-9); longer caudal peduncle 17.8-21.7% SL (vs. 14.8-17.4% SL); shorter preanal length 60.9-66.0% SL (vs. 69.0-73.0% SL); and interorbital width distinctly larger 28.4-33.0% HL (vs. 20.2-24.7% HL) (Ref. 104754). Description: Mouth sub-superior; Gill rakers on outer surface of first gill arch 14-16.; Vertebrae 4 + 32 (Ref. 104754). |
