A new species of the genus Cryptarcha (Coleoptera: Nitidulidae) from Solomon Islands

Cryptarcha solomonensis sp. nov. from Solomon Islands is described. This new species belongs to the strigata-group and is similar to C. australis Reitter, 1873, but distinct from it in the somewhat slenderer body with the yellow colouration on the elytra not reaching presutural parts in their anterior half, the longer and narrower aedeagus having one brush of hairs on the apex of the tegmen and in the different structure of its ovipositor. The diagnosis of the new species is compiled on the basis of comparison with other members of the strigata-group from Australia and adjacent islands.
