Abstract

Phloeonomus orientalis, a new species related to Phloeonomus pusillus (Gravenhorst), is described and illustrated from specimens from Kunashir Island in the Kuril Islands. A key to the four Palaearctic species related to P. pusillus is given.

Abstract

The systematic position of the monotypic genus Beeria Hatch 1957 within the subfamily Staphylininae is discussed. The genus combines characters of both the tribe Staphylinini and Quediini, however the morphology of the prothorax seems to justify its assignment to the tribe Quediini. A detailed description of the genus, together with the presently known data about its distribution and ecology are given. The type species of Beeria (punctata Hatch 1957) is identical with Philonthus nematocerus Casey 1915, which results in the following new combination: Beeria nematocera (Casey 1915) with punctata Hatch 1957 as a junior synonym. The characters distinguishing the tribes Staphylinini and Quediini are discussed in detail. A key to holarctic genera of the tribe Quediini is given. The subtribe Triacri established by Bernhauer (1931) within the tribe Quediini is identical with the subtribe Xanthopygi within the tribe Staphylinini. The genera Algon Sharp, Brachycamonthus Bernh. and Rientis Sharp are removed from the tribe Quediini and reassigned to the tribe Staphylinini, subtribe Xanthopygi. The genus Rientis Sharp, 1874 is identical with Securipalpus Schubert, 1908, which becomes a junior synonym of Rientis.

Abstract

The systematic position of the genus Derops Sharp, 1889 (several species in the Palaearctic and Oriental regions) within the family Staphylinidae and its relationship to the genus Rimulincola Sanderson, 1947 (one species in the eastern Nearctic region) are discussed. The genus Derops is shown to be congeneric with Rimulincola, which becomes a junior synonym of Derops. — The genus Derops is removed from the subfamily Phloecharinae and reassigned to the subfamily Tachyporinae as a separate new tribe Deropsini. A key to the tribes of Tachyporinae is given. — Derops kasugaensis (Sawada, 1956) is placed in synonymy with Derops longicornis Sharp, 1889. The published data on the ecology of species of Derops are summarized and detailed ecological observations by the author on D. divalis (southern Illinois) andD. longicornis (Japan, Honshu) are given and compared. The disjunct (eastern and/or midwestern North America-southeastern Asia) type of geographical distribution of Derops is discussed and compared with similar distributions of the syrphid genus Pterallastes Loew (Diptera and some plant genera). This distribution pattern is considered to be unique within the order Coleoptera.

Abstract

The original material of Leptacinus trigonocephalus Kraatz, 1859, L. tricolor Kraatz, 1859, and L. flavipennís Kraatz, 1859, was studied. L. trigonocephalus is assigned to the genus Leptacinus Er., the remaining two are re-elevated to species rank and assigned to the genus Phacophallus Coiff. All three are redescribed and figured. Original material of Phacophallus rubricollis (Reitter, 1899) and Phacophallus rubricollis (Casey, 1906) was studied, and both names were found to be junior synonyms of Phacophallus tricolor (Kraatz, 1859).-Lectotypes are designated for Leptacinus trigonocephalus Kraatz, Phacophallus tricolor (Kraatz), P. rubricollis (Reitter), P. rubricollis (Casey), and P. flavipennis (Kraatz).
