Name

• Halicmetus granulosus H.-C. Ho, 2022

• Type locality: 12°40.2’S, 48°9.6’ E, northern Madagascar, Mozambique Channel, Western Indian Ocean, 595‒605 meters.

• Diagnosis. A species of Halicmetus which is unique in having various-sized bucklers densely covering the body surfaces and that is further distinguished from congeners by the following combination of characters: body disk relatively small, disk width 59.7% SL; orbit small, its diameter 8.3% SL; interorbital moderately wide 7.4% SL; tail length 47.7% SL; illicial trough opening wide and high; dorsal fin absent in adult; pectoral-fin rays 13; uniformly creamy white when preserved; peritoneal membrane pale with dense melanophores and scattered black dots.

• Distribution: Only known from type locality.

• Etymology. The specific name of granulosus derived from the Latin granulis, which means granular, referring to the rough body surface with various-sized bucklers.
