Ctenotrypauchen

Specimens have been examined from the Philippines, Sumatra, and the Arafura Sea. The holotype is from China.

The few specimens that are known were collected between 50-70 m in the Indo-West Pacific. Based on the few specimens that exist in collections, it appears that this taxon may be confined to deeper waters than most other members of this subfamily

Ctenotrypauchen is unique within the ‘Trypauchen’ group in having, in combination, a serrated frontal crest with united, but slightly emarginate pelvic fins.

Total dorsal-fin elements 53-57; dorsal fin with six flexible spines followed by 47-51 segmented and branched rays; dorsal-fin base long and broadly joined with caudal fin; total anal-fin elements 41-46, no spines, first element segmented and branched; anal-fin height approximately equal to second dorsal-fin height; anal-fin membrane broadly joined with caudal fin; pectoral-fin rays 14-17, pectoral fin short and falcate
