description
C. minutus Pillai, 1963
description
Hapalogenyidae: Hapalogenys mucronatus (Eydoux & Souleyet, 1850); Hemiscyllidae: Chiloscyllium indicum (Gmelin, 1789); Nemipteridae: Scolopsis vosmeri (Bloch, 1792); Sciaenidae: Johnius dussumieri (Cuvier, 1830), J. glaucus (Day, 1876) (as Sciaena glauca), Pterotolithus maculatus (Cuvier, 1830) (as Otolithes maculatus); Serranidae Epinephelus septemfasciatus (Thunberg, 1793), Epinephelus akaara (Temminck & Schlegel, 1842), Epinephelus merra Bloch, 1793; Sparidae: Acanthopagrus schlegelii (Bleeker, 1854). Caligus epinepheli exploits a range of fish hosts, as summarised by Ho & Lin (2003).
discussion
Remarks: This species is extremely close to C. affinis in female body shape and proportions, especially the relatively short abdomen compared to the genital complex. We maintain it as a separate species on the basis of the difference in shape of the sternal furca, which has strongly incurved tines and a wide gape in C. affinis but only slightly incurved tines and a narrower gape in C. epinepheli. In addition the female postantennal process is weakly curved in C. epinepheli but strongly curved in C. affinis. There are also slight differences in the relative lengths of the distal spines on the fourth leg. The two subterminal spines are about equal in length and only slightly shorter than the terminal spine in C. affinis but all 3 distal spines differ in length in C. epinepheli, increasing in length towards the terminal spine. In this decision we are influenced by the known distribution patterns: C. affinis is only confirmed from the Mediterranean at present while C. epinepheli is an Indo-Pacific species unknown from the Atlantic.
