A NEW CROMPUS FROM NEW CALEDONIA (Hemiptera-Heteroptera: Lygaeidae)

Abstract

Crompus nesiotes is described from New Caledonia, and a new key to species is given. The ischnorhynchine genus Crompus was described by Stal (1874) for Crompus oculatus Stal from Australia. Scudder (1958) added a second species, C. opacus Scudder, keyed the two forms, and (1962) summarized the genus in his revision of the Ischnorhynchinae of the world. Since the genus has been confined to Australia, a species from New Cale­ donia is of real interest. As might be expected, the aedeagus of the new Crompus (fig. 1) is very much like that of Neocrompus (See Ashlock & Scudder 1966: fig. 1 f. Neocrom- pus zimmermanni), differing in the shape of the phallothecal process and in the lack of a vesical lobe present on the Neocrompus. All measurements are in millimeters.
