Issue
The species was placed in the genus Bathyphasma Gilbert, 1896 by Balushkin (2012), genus he resurrected on the basis of a few characters. He was followed by authors thereafter but with no supplementary evidence. Orr et al. (2019) did not support the resurrection from their phylogeny, on the basis of a lack or morphological synapomorphies with other sister-species, which we follow in FishBase and WoRMS. As Bathyphasma ovigerum Gilbert 1896 in ECoF (March 2024).

This species is distinguished from its congeners by the following set of characters: both jaws with narrow rows of stout, sharp, simple, recurved teeth; a moderate-sized gill opening which extends ventrally to pectoral rays 4-8; pelvic disk large 25-38% HL; cephalic pore pattern 2-6-7-1; most similar to C. lycopersicus and C. kamikawai, which are both distinguished from C. ovigerus by their broad bands of trilobed teeth (Ref. 91047).

The holotype, a male, was found to carry developing eggs in its mouth (Ref. 6885). Two females were ripe with large yolked eggs 6-7 mm in diameter, while the male of 33.0 cm SL had enlarged testes. Two smallest and immature females examined (18.0-18.5 cm SL) had small ovaries with many small white eggs ca. 1 mm in diameter (Ref. 91047).
