REMARKS

Ommatocarcinus pulcher View in CoL was described from one large (cl 15 mm, cw 37 mm) male specimen collected from a fish stomach in South Africa ( Barnard 1950: 286, fig. 53 b-f). The holotype could not be examined during this study but the description and detailed illustrations (including the G1) in Barnard’s description are clear and reasonably complete. The species is close to O. macgillivrayi View in CoL , in terms of the shape of the carapace (anterolateral teeth are absent) and a similar G1. Takeda & Miyake (1969b: 174) had suggested that it was a synonym of White’s species. One difference, however, is that the eye peduncles extend slightly beyond the outer orbital teeth in O. pulcher View in CoL ( Dai & Yang 1991: pl. 55, fig. 3), whereas in O. macgillivrayi View in CoL only the distal margins of the eyes, not the eye peduncles, extend beyond the teeth ( Dai & Yang 1991: pl. 55, fig. 2, as O. macgillivaryi [sic]). Other differences are the absence of the small distal tooth on the merus of each of the ambulatory legs (P2-P5) and of the median tooth on the cheliped merus that are characteristic of O. macgillivrayi View in CoL . The G1 of O. pulcher View in CoL is slightly less pointed than that of O. macgillivrayi View in CoL (see Dai & Yang 1991: figs 199-1, 199-2; Hsueh & Huang 2002: figs 3F, G). The stridulating ridge on the proximal edge of the outer (dorsal) margin of the cheliped merus ( Barnard 1950: fig. 53 e; Dai & Yang 1991: fig. 199-3) is less pronounced in O. pulcher View in CoL than in O. macgillivrayi View in CoL although the difference may be due to size since only large specimens of the latter were examined.

The Japanese records of O. macgillivrayi appear to be referable to O. pulcher (see Remarks for O. macgillivrayi above). Ommatocarcinus sp. ( Yokoya 1933), known from three Japanese specimens that could not be examined, also appears to represent O. pulcher since the meri of the ambulatory legs are similarly unarmed ( Yokoya 1933: 198, fig. 65). Material from Vietnam identified by Zarenkov (1972: 234, fig. 1-2) as “ Ommatocarcinus sp. Yokoya?” could not be examined or identified by the information provided.
