Mioptachys flavicauda (Coleoptera: Carabidae: Bembidiini: Xystosomina), nový druh střevlíčka pro Českou republiku a Evropu

Abstrakt: The first record of an adventive species Mioptachys flavicauda (Say, 1823) (Coleoptera: Carabidae: Bembidiini: Xystosomina) from the Czech Republic and Europe is presented. A specimen was collected at one locality in the Czech Republic (the Chateau Park near the village of Krásný Dvůr, Podbořany environs) where it was attracted to UV light (light-trapped). Mioptachys flavicauda originates from the Nearctic Region, where it lives under the bark of trees, like the related European autochthonous species Tachyta nana nana (Gyllenhal, 1810). Since American species of trees were imported into the park in the 18th and 19th centuries, it cannot be ruled out that the specimen found comes from a viable local population. Mioptachys flavicauda differs from T. nana nana by the following features: the antennae are shorter, the fourth to tenth antennomeres are as wide as long (moniliform), it has a considerably broader pronotal margin, the elytra are obliquely truncate before the apex, brown with the apical third usually lighter, and the body is only two-thirds of the length.
