Pseudorhabdosynochus huitoe Justine, 2007 View in CoL

Type host: Epinephelus maculatus (Bloch) (Serranidae) .

New Host: Epinephelus cyanopodus Richardson (Serranidae) .

Site: Between secondary gill lamellae.

Material examined: 8 specimens, 4 ‘picrate’ (p), 4 ‘unflattened carmine’ (uc).

Comparative material examined: Type specimens, MNHN .

Material deposited: vouchers, MNHN JNC 1530, 1901, 1902.

Prevalence: 18 % (3/17) in all fish (Table 2); 0% (0/12) in large fish with ‘specific’ fauna ( Table 10); 100% (3/3) in small fish with ‘foreign’ fauna ( Table 10).

Intensity: See Table 2; maximum calculated intensity 10; this species represented 0.5% of the total number of monogeneans.

Short description. [Limited to selected measurements of 4 uc specimen from JNC 1902 and 2 p specimens from JNC 1530, measurements in original description indicated as OD]. Quadriloculate organ inner length uc 47 (42–50), p 60–64, OD 45; cone length uc 12 (11–13), p 10–13, OD 13; tube length uc 12 (10–13), p 12–16, OD 15; sclerotised vagina total length uc 19 (16–21), c 25–27, OD 25; lateral (dorsal) bar length uc 76 (73–80), c 78–87, OD 84; ventral bar length uc 112 (95–120), p 120, OD 119. Structure of sclerotised vagina very similar to that of specimens from the type-host. The specimens were mature with fully developed ovary and testis.

Remarks. Based on the structure of their sclerotised vagina, quadriloculate organ and their measurements, these specimens are similar to the type-specimens of P. duitoe from the type-host, E. maculatus . As for P. duitoe , see the remarks about the role of spawning aggregation on monogenean infection.
