Etymology: Doryrhamphus: Greek, dory = lance + Greek, rhamphos = bill, beak (Ref. 45335).
Issue
Issue on validity of subspecies: subspecies considered as valid in FB, synonymized with the species Doryrhamphus excisus Kaup, 1856 in Eschmeyer (CofF ver. Mar. 2011: Ref. 86697). Please send references, or more studies are needed.

Οικολογία
Θαλασσινό(ά) Υφαλόφιλο(α); εύρος βάθους 0 - 8 m (Ref. 112725), usually 3 - 8 m (Ref. 112725). Tropical
Western Indian Ocean: endemic to the Red Sea from the Gulf of Suez south to Massawa and Jiddah on the east coast. It was noted by Dawson (Ref. 5316) that there is a clinal increase in the number of total rings and dorsal rays for the 3 subspecies; more study is needed (Ref. 86689).
