Trachonurus robinsi, a New Species of Grenadier (Gadiformes, Macrouridae) from the Philippines

Trachonurus robinsi is described from 26 specimens collected by the steamer Albatross in the semi-enclosed basins of the Sulu, Camotes, Mindanao, and Sibuyan seas, where it is apparently endemic. It is a species of small adult size, probably not longer than about 25 cm in total length, and is characterized by its relatively low count of pectoral fin rays and scale rows on body, short barbel, narrow suborbital, and high spinule count on body scales. Two related species, T. sentipellis Gilbert and Cramer and T. sulcatus (Goode and Bean), previously placed in the synonymy of T. villosus (Günther), are considered valid.
