Lumpenidae
(subfamily of Stichaeidae—Makushok, 1958)
by V. M. Makushok
Elongate, slightly compressed fishes, to 50 cm SL in Clofnam area (usually around 10-30 cm). No fleshy appendages on head; mouth terminal or slightly inferior; gill openings continued forward, membranes narrowly joined to isthmus, branchiostegal rays 6; scales present on cheeks (but covering entire head in the North Pacific Lumpenella). Sensory canals absent on head (except perhaps in the North Pacific Poroclinus), represented by lines of neuromasts. Dorsal fin long, from a little behind head to caudal peduncle (or joined to caudal fin in some); anal fin also long (and joined to caudal fin in some); pectoral fins large; pelvic fins in advance of pectoral fins (jugular), with I + 3 finrays (the soft finrays not branched). Scales small, no lateral line canal, but a mid-lateral line of neuromasts.
Genera 6; in Clofnam area 3.

Note. Makushok (1958: 87-96) argued that the family Lumpenidae should be placed as a subfamily of the Stichaeidae, since the genus Lumpenopsis (for which Allolumpenus is probably a junior synonym) is closely related to the genera of the North Pacific subfamily Stichaeinae (and other subfamilies of the Stichaeidae). To conform with Clofnam, however, the Lumpenidae is here kept distinct.
