description

Description. Morphometric data is presented in Table 3. Dorsal-fin rays X, 15; anal-fin rays, III, 7; all dorsal- and anal-fin rays branched; pectoral-fin rays 20, all but uppermost branched; pelvic-fin rays I, 5, all soft rays branched; caudal-fin rays: principal 15, procurrent 6 dorsally and 6 ventrally, posteriormost 3 of both sides segmented; branchiostegal rays 7. Gill rakers on first arch 13 + 26, total 39. Tubed lateral line scales 38. Rows of scales on cheek 9; rows of scales between origin of anal fin and lateral line 12, between lateral line and mid-base of spinous dorsal fin 1.5, between origin of dorsal fin and lateral line 5. Circumpeduncular scales 18. Supraneural bones two; precaudal vertebrae 10, caudal vertebrae 16, total 26. Body oblong, laterally compressed. Head large, more than one third of the SL. Orbit diameter larger than snout length, 8.4 % of SL and 24.7 % of head length. Upper profile of interorbital straight to slightly convex. Nostrils close together, internarial distance contained 8.7 times in snout length. Posterior nostril large, oval shaped; anterior nostril in a tube much wider at base than at distal tip. Upper limb of preopercle smooth on upper on

A new species of Anthiadinae (Teleostei: Serranidae) from São Pedro and São Paulo Archipelago, Brazil, Equatorial Atlantic.

diagnosis

Diagnosis. The new species differs from its only Atlantic congener by a combination of several characters: pectoral-fin rays 20; total gill rakers on first arch 39; vomerine tooth patch with a posterior prolongation; pelvic fin not reaching base of last anal-fin ray; dorsal, anal, and pelvic fins scaleless; and coloration (dorsal, anal, and pelvic fins mostly dark red).
