A revision of the Eastern Palaearctic species of Myrmecopora Saulcy, 1864 with notes on some species from the Oriental region (Coleoptera: Staphylinidae, Aleocharinae, Falagriini).

Abstract

The types and further material of the Eastern Palaearctic Myrmecopora rufescens (Sharp), M. algarum (Sharp), M. martensi (Pace), and the Oriental M. chinensis Cameron, M. elegans Cameron and M. nilgiriensis Cameron are revised. M. rufescens, M. algarum, M. chinensis and the new species M. reticulata sp. n. are recognized as a monophylum and placed in Lamproxenusa subgen. n. of the genus Myrmecopora Saulcy. M. martensi (Pace) and M. elegans Cameron are transferred to Anaulacaspis Ganglbauer, M. nilgiriensis Cameron to the falagriine genus Indomyrmecopora gen. n. Lectotypes are designated for Tachyusa rufescens Sharp, T. algarum Sharp and Myrmecopora chinensis Cameron. For the species of Myrmecopora and Indomyrmecopora and the new supraspecific taxa descriptions and drawings of relevant characters are presented. A diagnostic key is provided for the species of Lamproxenusa.
