Etymology: Hydrolagus: hydro-, combining form of hydor (Gr.), water; lagos (Gr.), hare, i.e., “water rabbit,” probably referring to three pairs of tooth plates, which tend to protrude from the mouth like a rabbit’s incisors. (See ETYFish); melanophasma: melanos (Gr.), black, referring to color in life; phasma (Gr.), ghost or specter, alluding to the vernacular “ghostshark” (literally, a black ghost). (See ETYFish).

簡短描述
型態特徵 | 形態測量圖
A species of the genus Hydrolagus based on the absence of an anal fin. Hydrolagus
melanophasma sp. nov. is distinguished from other chimaeroids by a blunt snout with minimal sloping from the orbit to the snout tip, a large slightly curved dorsal fin spine (25.9 % BDL) extending beyond first dorsal fin apex, and a long second dorsal fin (77.3–81.1% BDL) of uniform height throughout. The pectoral fins are large, reaching beyond the pelvic fin insertion when laid flat, trifid claspers forked for 27–27.8% of the total clasper length and the preopercular and oral lateral line canals branch separately or together from the infraorbital canal. Coloration after preservation is a uniform black with no distinct mottling or markings (Ref. 82286).
