Callochiton clausadeae Kaas & Van Belle, 1985 View in CoL

( Figures 4A–C View FIGURE 4 )

Callochiton clausadei Kaas & Van Belle 1985: 42 View in CoL , fig. 17 (incorrect denomination, emended by Kaas 1986). Callochiton clausadeae View in CoL ; Dell’Angelo et al. 2004: 51, pl. 3, figs 1–3 (bibliography and synonymy).

Type: MNHN (holotype + seven paratypes) , RMNH K 4993 About RMNH /1 (paratype) .

Type locality: Madagascar, Tuléar , in caves, outer slope, 4–34 m.

Material examined: M13: 30 valves (4 head, 20 intermediate and 6 tail); M19: 2 intermediate valves; M20: 1 intermediate valve; M26: 7 valves (1 head, 4 intermediate and 2 tail); M65: 6 valves (3 intermediate and 3 tail); MLD01A: 6 valves (1 head, 4 intermediate and 1 tail); MLD02A: 12 valves (2 head, 8 intermediate and 2 tail); MLD03A: 4 valves (3 intermediate and 1 tail); MLD04B: 1 intermediate valve; MLD05A: 2 intermediate valves; MLD05B: 3 intermediate valves; LB04: 1 intermediate valve; LB05: 18 valves (2 head, 11 intermediate and 5 tail).

Remarks: A detailed description of this species is given by Kaas & Van Belle (1985). Collected valves agree with those of C. clausadeae , although their preservation is not very good. The only appreciable difference found relates to its slit formula, 12–16/1/12–15 vs. 18/1/12 reported by Kaas & Van Belle (1985). Also the pits in pleural areas are variable in number, up to 7–8 vs. 4–6 reported by Kaas & Van Belle (1985); some are more elongated and the outer ones can reach the anterior margin.

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

Distribution: Callochiton clausadeae is reported from Madagascar, Mauritius, Réunion, and the Maldive Islands.
