Type locality. The type series came from Indonesian localities: Batjulmati, Java (reef); Labuhan Badjo, western Flores (to 40 m) ; between Misool and New Guinea (32 m) : and Djedan , Kepulauan Aru (13 m) .

Distribution. Arabian Sea to Indonesia. Australia; Western Australia; 13– 120 m.

Remarks. This species resembles Philocheras brucei Komai, 2004 , known only from the type locality in Queensland because of the narrow setose rostrum and midlateral spine on the antennal scale. P. angustirostris is readily distinguished by the interrupted dorsal carina (which is continuous in P. brucei ).
