Abstract
Gerres methueni Regan, 1920, for many years identified asG. rappi (Barnard, 1927), is redescribed as a senior synonym of the latter species, following examination of two syntypes of the former and comparative material from South Africa and Madagascar.Gerres methueni is characterized by prominent dark stripes along the scale rows above the lateral line and the 4 or 5 rows immediately below it, 5–17 small scales on the preopercular flange, arranged in 1–3 scale row(s) at the corner, 42–44 pored lateral line scales+3–5 additional pored scales on the scaly sheath of the caudal fin base, 41/2–51/2 scales between the fifth dorsal fin spine base and lateral line, and second dorsal fin spine length equal to or slightly shorter than the third dorsal fin spine length.Gerres methueni is currently known from South Africa, southern Mozambique and Madagascar, being endemic in those areas.
