Remarks. This comparatively genus-rich and morphologically disparate family is also relatively weakly demarcated from the families Tanaellidae and Leptognathiidae (Larsen 2005) and future revisions based on updated phylogenetic analyses will undoubtedly restructure this classification. It is also almost certain that the family is, in reality, much better represented in Japanese waters, Japan Trench, and the Kurile-Kamchatka Trench than indicated by the few taxa recorded in this study.
