| Summary: | Caligus sciaenops Pearse, 1952 Syn: C. setosus Pearse, 1953 C. cresseyi Ho & Lin, 2003 C. epinephali [sic]: Cressey (1991) Differential diagnosis: Female genital complex and abdomen combined about 1.2 times longer than cephalothorax; body length 3.1–4.2 mm. Male body length unknown. Female genital complex subrectangular, without distinct postero-lateral lobes; about as long as abdomen. Abdomen 2-segmented, first segment markedly longer than second. Male abdomen 2-segmented, first segment about half length of second. Post-antennal process large and strongly curved in female. Antenna claw not strongly curved. No additional process present between post-antennal process and base of antenna in female. Sternal furca with long, tapering tines. Female maxilliped with smooth medial margin. Exopod of leg 1 with seta at inner distal angle longer than longest spine but shorter than segment; no vestiges of posterior margin setae; first exopodal segment broad, with strongly convex posterior margin. Outer margin of second endopodal segment of leg 2 ornamented with fine spinules. Distal spines on exopod of leg 4 all similar in length but terminal spine just longer than other 2. Material examined: none Distribution: Jamaica, Gulf of Mexico (Texas coast). Hosts: Sciaenidae: Sciaenops ocellatus (Linnaeus, 1766), Cynoscion nebulosus (Cuvier, 1830), Cynoscion nothus (Holbrook, 1848), Leiostomus xanthurus Lacepède, 1802. The only known hosts of C. sciaenops are sciaenids (Pearse 1952; 1953; Cressey 1991). Remarks: Cressey (1991) placed C. sciaenops in the synonymy of C. haemulonis with no discussion. The general body size and shape given by Pearse (1952) is consistent with C. haemulonis and, although the proportional lengths of the two abdominal segments in the female do not match with the description of C. haemulonis , the abdomen appears abnormally slender in Pearse’s figures of females (Pearse 1952: Fig. 49, 59). The male figured by Pearse (1952: Fig. 58) has a 2-segmented abdomen and the proportional lengths of the two ... |
