Ctenotrypauchen chinensis Steindachner 1867

Ctenotrypauchen chinensis 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

The few specimens that are known were collected in the Indo-West Pacific at a depth of 50-70 m. 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.

Trypauchen taenia Koumans, 1953: 279, fig. 69 (type locality, Sumatra, Indonesia)

Distinguished by the following: serrated frontal crest with united, bur slightly emarginate pelvic fins; total elements in dorsal fin 53-57; total elements in anal fin 41-46, pectoral-fin rays 14-17; pelvic-fin rays I, 3-5; anal-fin pterygiophores preceding the first hemal spine (AP) 3-4; caudal vertebral count 23-25; longitudinal scale rows 48-66 (Ref. 078624).

Dorsal soft rays (total): 53 - 57; Analsoft rays: 41 - 46

This species was collected at depths of 62-65 in the Arafura Sea and 50-70 m from the Samar Sea; possible that this species may be confined to deeper waters than most other members of this subfamily (Ref. 78624).

Ctenotrypauchen chinensis is a species of goby native to fresh waters of China. This species is the only known member of its genus.
