Centropomus poeyi Chávez, 1961: 75 (original description; Mexico)
Type. USNM 196622, 233 mm SL (Fig. 16), loc.: Mexico.
The holotype determined by Chávez (1961) is a 230 mm SL specimen deposited in Estación de Biologia Marina, Instituto Tecnologico de Veracruz, Mexico (EBMTV 235). However, the type specimen and 15 of 27 paratypes were lost (Rivas 1986). The neotype (USNM 196622) designated by Rivas (1986) is a 233 mm SL specimen from Mexico, deposited in the Muséum national d’Histoire naturelle.
Diagnosis. Centropomus poeyi differs from its congeners as follows:
Western Atlantic: from C. undecimalis, by having 69–74 scales on lateral line to caudal-fin base (vs 66–75), 9–12 lower limb gill rakers on the first arc (vs 8–11), 15–18 gill rakers on first arch (vs 11–14), and second dorsal fin with I,9 (vs I,11); from C. irae, by having 69–74 scales on lateral line to caudal-fin base (vs 79–96), 9–12 lower limb gill rakers on the first arc (vs 7–8), 15–18 gill rakers on first arch (vs 11–13), and second dorsal fin with I,9 (vs I,11); from C. parallelus, by having 69–74 scales on lateral line to caudal-fin base (vs 64–70), 9–12 lower limb gill rakers on the first arc (vs 10–13), pelvic fin not reaching the anus (vs pelvic fin usually reaching the anus), and second dorsal fin with I,9 (vs I,11); from C. ensiferus, by having 69–74 scales on lateral line to caudal-fin base (vs 48–58), 9–12 lower limb gill rakers on the first arc (vs 10–15), and second dorsal fin with I,9 (vs I,11); from C. pectinatus, by having 69–74 scales on lateral line to caudal-fin base (vs 47–52), 9–12 lower limb gill rakers on first arc (vs 14–16), 15–18 gill rakers on first arch (vs 20–23), pelvic fin not reaching the anus (vs pelvic fin reaching the anus), second dorsal fin with I,9 (vs I,11), anal fin with III,7 (vs III,8).
Eastern Pacific: from C. nigrescens, by having 9–12 lower limb gill rakers on first arch (vs 8–9); 15–18 gill rakers on first arch (vs 11–14), and second dorsal fin with I,9 (vs I,11); from C. viridis, by having 69–74 scales on lateral line to caudal-fin base (vs 67–75), and 15–18 gill rakers on first arch (vs 14–15); from C. armatus, by having 69–74 scales on lateral line to caudal-fin base (vs 47–59), 9–12 lower limb gill rakers on first arch (vs 11–12); the longest anal-fin spine not reaching caudal-fin base when adpressed (vs longest anal-fin spine reaching caudal-fin base), and second dorsal fin with I,9 (vs I,11); from C. robalito, by having 69–74 scales on lateral line to caudal-fin base (vs 47–59), 9–12 lower limb gill rakers on first arch (vs 14–17); 15–18 gill rakers on first arch (vs 21–25), the longest anal-fin spine not reaching caudal-fin base when adpressed (vs longest anal-fin spine reaching caudal-fin base), and second dorsal fin with I,9 (vs I,11); from C. unionensis, by having 69–74 scales on lateral line to caudal-fin base (vs 46–52), and 9–12 lower limb gill rakers on first arch (vs 10–14); from C. medius, by having 69–74 scales on lateral line to caudal-fin base (vs 53–65), 9–12 lower limb gill rakers on first arch (vs 14–16); 15–18 gill rakers on first arch (vs 18–23), anal fin with III,7 (vs III,8), and second dorsal fin with I,9 (vs I,11).
Distribution. Centropomus poeyi occurs along the coast of Mexico, from Tampico (Tamaulipas) to Frontera (Tabasco). Centropomus poeyi and C. irae have the most restricted distributions when compared to Western Atlantic congeners.
Remarks. No specimens of Centropomus poeyi were directly examined in the present study. Diagnosis and distribution were based on Chávez (1961) and Rivas (1986).
