Gerald R. Allen and John E. Randall: A review of the leucogaster species complex of the Indo-pacific pomacentrid genus Amblyglyphidodon, with descriptions of two new species, pp. 139-152

Abstract

The Indo-Pacific pomacentrid Amblyglyphidon leucogaster was previously thought to consist of several distinct geographic colour variations. However, the present study indicated there is a complex of four species: A. leucogaster (Bleeker) from the western Pacific and eastern edge of the Indian Ocean, A. orbicularis (Hombron & Jacqinot) from Samoa, Fiji, and New Caledonia, and two new species described herein – A. indicus from the Red Sea and Indian Ocean, and A. melanopterus from Tonga. The members of the leucogaster complex are mainly differentiated by a combination of colour pattern and gill-raker counts. A key to the species of Amblyglyhidon is included.
