K výskytu Emus hirtus na území České republiky (Coleoptera: Staphylinidae)

Abstrakt: Emus hirtus (Linnaeus, 1758) is a coprophilous species inhabiting natural pastures where it feeds on the larvae of coprophagous Coleoptera and Diptera. In the past century the species was relatively abundant in the territory of the Czech Republic, but in 20th century it started to disappear in connection with the restriction of pasturage. Since 1957 the species hasn’t been verified in this territory. Two new records are published in this paper: two specimens were caught at a municipal dump (Bohemia centr.: Poděbrady, square 5856, 20.x.1978) and one on a roe carrion nearby Ostrava-Koblov (Silesia, square 6175, 19.v.1996). Therecent occurrence of stable populations in the Czech Republic is debatable because optimal habitats are absent now. The species probably migrates and constitutes only unstable temporary populations in substitute habitats.
