( Figs 25A–D View FIGURE 25 )
Hosts: Thunnus albacares (Bonnaterre) ; Katsuwonus pelamis (Linnaeus) ; Euthynnus affinis (Cantor) ( Scombridae : Scombriformes); Coryphaena hippurus Linnaeus ( Coryphaenidae : Carangiformes)
Locality: Off east coast South Africa (Indian Ocean)
Material examined: 5♀ + 3♂
Material collected: 7♀ + 4♂ from T. albacares ; 26♀ + 34♂ from K. pelamis ; 6♀ + 10♂ from E. affinis ; and 38♀ + 34♂ from C. hippurus
Voucher material: 2♀ + 2♂ ( SAMC-A099210 ) from E. affinis deposited in the Iziko South African Museum , Cape Town, South Africa .
Adult female ( Fig. 25A View FIGURE 25 ) genital complex longer than wide, posterolateral corners slightly lobate; abdomen 3-segmented, shorter than genital complex; antenna (a2) with short, rounded proximal process (arrowed); post-antennal process absent ( Fig. 25B View FIGURE 25 ); maxillule with dentiform posterior process (mpp) short, robust ( Fig. 25B View FIGURE 25 ); sternal furca (sf) small with short, blunt ending, divergent tines with marginal flanges ( Fig. 25B View FIGURE 25 ); leg 1 last exopodal segment with 3 posterior pinnate setae, terminal spines 2 and 3 robust with serrated margins (arrowed) and accessory processes ( Fig. 25C View FIGURE 25 , cf. Fig. 81A in Ho & Lin (2004)); leg 4 3-segmented with I, I, III spines (arrowed) respectively ( Fig. 25D View FIGURE 25 ) (cf. Cressey & Cressey 1980; Ho & Lin 2004).
Remarks: The structure of leg 4 (with I, I, III spines) is similar to those of the C. diaphanus -group, but none of the remaining characteristics conform to those of the group.
The report includes two new host records i.e. T. albacares and C. hippurus off South Africa.
