Kemponia calmani (Tattersall, 1921) comb. nov.

Periclimenes calmani Tattersall, 1921: 385 –386, pl. 27, fig. 11, pl. 28, figs. 4–15. — Gurney, 1927: 229, 264, figs 66–69. — Bruce, 1987a: 1415 –1425, figs. 1–5. — Li, 2000: 165 –166, fig. 204.

Periclimenes (Ancylocaris) calmani — Kemp, 1922: 176.

Type material. Lectotype Ψ, BMNH 1921.12.19.44; 3 Ψ paralectotypes BMNH 1921.12.19.45–47.

Type locality. Sudan, Red Sea coast, precise locality not designated.

Habitat. No data.

Bathymetric range. Shallow water.

Larvae. Zoeal Stages 1–5 (Gurney, 1927).

Distribution. Known also from Egypt, Sudan, Malaya, Singapore, Indonesia, and eastern Mediterranean Sea (Monod, 1930; Duris, 1987).

Remarks. One of the two pontoniine shrimps to have spread from the Red Sea to the Mediterranean Sea. The status of Johnson’s specimens referred to this species, from Malaya and Singapore (Johnson, 1962), need to be re­assessed. Unfortunately it is unlikely that this material is still extant (P.K.L. Ng, pers. com.).

The Indonesian specimens described by Holthuis (1952), as Periclimenes (Harpilius) ? calmani, one from 120–400 m, seem unlikely to be conspecific with the shallow water species and are intermediate with Periclimenes leptopus Kemp, 1922 . It is at present uncertain whether or not P. leptopus, a shallow water species, in the collection of the Zoological Survey of India, should be referred to the genus Kemponia .
