[[ Genus Allocareproctus Pitruk & Fedorov ]]

The genus Allocareproctus Pitruk & Fedorov was originally erected for the single species Careproctus jordani Burke (a replacement name for C. gilberti Jordan & Thompson ). Until the collection of 15 additional specimens from the Kuril Islands (Pitruk & Fedorov 1993), Careproctus jordani had been known only from the holotype collected in or before 1911 from Sagami Bay, Japan. This specimen was subsequently redescribed by Burke (1930) and Kido (1988). Based on their new material, Pitruk & Fedorov (1993) concluded that the distinctive morphology of the species warranted generic rank and established the genus Allocareproctus . According to Pitruk & Fedorov (1993), Allocareproctus is distinguished from other liparid genera by the presence of small whisker-like papillae on the pores of the upper portion of the head, the extension of the symplectic to the medial aspects of the quadrate and the metapterygoid, and the protrusion of the ends of the anterior rays of the dorsal fin beyond the connective membrane.
