Trapezia rufopunctata (Herbst, 1799)

Cancer rufopunctatus Herbst, 1799: 54, pl. 47, fig. 6 (colour).

Grapsillus maculatus Macleay, 1838: 67 .

Trapezia acutifrons A. Milne Edwards, 1867: 281 .

Quadrella rufopunctata Chen, 1933: 111, fig. 55 (junior homonym of Cancer rufopunctatus Herbst, 1799)

Remarks. The taxonomy of this species is now quite stable. Ng & Ahyong (2000) showed that the lectotype of Grapsillus maculatus Macleay, 1838 was still extant (in the Macleay Museum, University of Sydney) and that it fits the concept of T. rufopunctata as currently understood (see Galil & Lewinsohn 1985: 209; Castro 1997a: 127).

The dried male and female syntypes of Trapezia acutifrons A. Milne Edwards, 1867 (MNHN­B 2913) from the Hawaiian Islands are clearly identical to T. rufopunctata . From its description, but not the figure (Chen 1933: 111, fig. 55), Quadrella rufopunctata (type locality Sri Lanka) (not Cancer rufopunctata Herbst, 1799) is almost certainly T. rufopunctata .
