Distinguished from other hardyheads by a combination of the following characters (expressed in mean): greatest body depth (mean 4.9), least body depth (mean 10.3) both in SL; eye 3.0 in head; midlateral scale count (mean 31.4). Osteologically diagnosed by the combination of the following: dentition, shape of urohyal, medial wing of pelvic bone and premaxilla. Differs further in lacking ventral processes on fifth ceratobranchial for attachment of pharyngoclavicularis internus muscle (Ref. 26685). Description: first dorsal fin spines 6, 5-6; second dorsal fin Ii5, Ii5-6; anal fin Ii7, Ii6-7; pectoral fin Ii12, Ii10-13 (Ref. 26685). |
