Apogon soloriens, a new species of cardinalfish (Perciformes: Apogonidae) from the Bonin Islands, Japan

The new cardinalfish Apogon soloriens is described on the basis of nine specimens collected from the Bonin Islands (northern island chain of Ogasawara Islands), Japan. The new species resembles Apogon caudicinctus Randall and Smith 1988 in coloration, lacking a black band below the second dorsal fin but with a black band on the caudal peduncle, but differs in having 13 pectoral-fin rays (vs. 12 rays in A. caudicinctus), greater interorbital width [9.1-11.1% of standard length (mean 9.8%) vs. 6.6-7.9% (7.3%)], and a wider blackish band on the caudal peduncle (vs. narrower black band). A key to the Apogon talboti look-alike group is provided.
