Abudefduf conformis and Plectroglyphidodon sagmarius, two new damselfishes (Pomacentridae) from the Marquesas Islands
Two new species of damselfishes (Pomacentridae) are described from the Marquesas Islands, Abudefduf conformis, previously identified as A. saxatilis (Linnaeus) or A. vaigiensis (Quoy & Gaimard), and Plectroglyphidodon sagmarius, formerly cited as P. imparipennis (Vaillant & Sauvage). A. conformis is distinct from the Indo-Pacific A. vaigiensis in having modally 13 instead of 12 anal soft rays, usually 22 instead of 21 tubed lateral-line scales, 27-30 instead of 24-28 gill rakers, and in color (edges of scales darker, dark bars narrower, and no yellow dorsally on body). P. sagmarius is distinct from the Indo-Pacific P. imparipennis in having modally 19 instead of 20 pectoral-fin rays, deeper body (2.1-2.35 in SL, compared to 2.3-2.45 in SL) and in color (a black saddle on caudal peduncle and three brownish yellow bars on body, not present in P. imparipennis).
