Elsewhere the species is widespread in the tropical, west-central Pacific: Cocos (Keeling Islands) east to Papua New Guinea, Australia, New Caledonia, north to the Northern Mariana and Marshall Islands and eastwards to French Polynesia. 
Forms loose aggregations on steep outer reef slopes and drop-offs with caves and ledges, at depths to 95 m.

Etymology

The species is named alpha from the Greek alphos (= white-spotted), as from leprosy, in reference to the pale spots on the head and body. Also the name was chosen because alpha is the first letter of the Greek alphabet. This fish was first diagnosed and illustrated by Gerald R. Allen (1975) who referred to it as Chromis sp. "A".
