Cryptoplax sykesi Thiele, 1909 View in CoL

( Figures 11M–O View FIGURE 11 )

Cryptoplax sykesi Thiele 1909: 54 View in CoL , pl. 6, figs 83–86; Leloup 1940: 9, fig. 3, pl. 2; Ghobashy & Kotb 2002: 6; Anseeuw & Terryn 2004: 16, fig. 55; Dell’Angelo et al. 2004: 60, pl. 6, figs 14–15 (bibliography and synonymy).

Type: unascertained (fide Ferreira 1983: 287).

Type locality: Red Sea, “Gimsah-Bai”.

Material examined: M13: 1 intermediate valve; M20: 2 intermediate valves; M65: 2 intermediate valves; MLD02A: 2 intermediate valves; LB04: 1 intermediate valve; LB05: 21 valves (20 intermediate and 1 tail).

Remarks: Detailed descriptions of this species are given by Leloup (1940) and Ferreira (1983).

We attribute our valves to Cryptoplax sykesi on the basis of the smooth jugal area and the sculpture of the lateropleural area, with 5–6 longitudinal riblets, some broken up in granules near the apex ( Fig. 11O View FIGURE 11 ). Our material match with the valves found in Madagascar (compare pl. 6, Figs 14 View FIGURE 14 –15 in Dell’Angelo et al. 2004), only the Maldive intermediate valves seem more elevated than the Madagascar ones.

This is the first report of this species from the Maldive Islands.

Distribution: Cryptoplax sykesi is an intertidal to shallow sublittoral species, widespread in the western Indian Ocean. It is known from the Red Sea, Somalia, Tanzania, Mozambique, Natal, Amirante Islands, Geyser Bank (North of Mozambique Channel), Madagascar and the Maldive Islands.
