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).

背棘 (總數) : 0; 背的軟條 (總數) : 40 - 45; 臀棘: 0; 臀鰭軟條: 35 - 36; 脊椎骨: 45 - 50. 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).
背鰭與臀鰭與尾鰭匯和鰭; 胸鰭的上半部圓形的與長度漸減均勻地的鰭條到大約來自底部的第六個, 像那些緊鄰下方, 是長度增加很多而突出的; 演變成的腹鰭形成一個大又幾乎圓形的黏盤。 (參考文獻 6885)
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).
