A6228780FFDDFF92DED03FC0FB12FE44.taxon	description	A new country record for Poland, A. variolatum stands out among other species of this genus due to the clearly marked and dense punctation on the prothorax, especially at its base, and the black coloration of the antennae. Only A. coarctatum has equally clear and dense punctation of the prothorax, however, its antennae are bright yellow. Currently, A. variolatum is only reported from five European countries: Croatia (Dalmatia), France (Upper Savoy), Switzerland (Canton of Vaud), Germany (Brandenburg), and Austria (Besuchet 1971; Sörensson 2015). The species seems to be widely distributed in central Europe (Besuchet 1976). In the German Red List, it is listed as an extinct species (Binot et al. 1998). This beetle inhabits damp habitats and is found in swampy areas, among mosses and sedges. In Brandenburg, Germany, it was collected from under lichens (Koch 1989).	en	Komosiński, Karol, Marczak, Dawid (2018): Four Species of Ptiliidae (Coleoptera) New to Poland.

A6228780FFDDFF94DCD33E29FEB6FA9E.taxon	description	We report M. palustre in Poland for the first time. Both Microptilium species are very similar and differ slightly in terms of color. Microptilium palustre is subtly darker, black-brown. A confirmed determination of the species is based on the anatomy of the spermatheca, of which illustrations can be found in Besuchet’ s key (1971).	en	Komosiński, Karol, Marczak, Dawid (2018): Four Species of Ptiliidae (Coleoptera) New to Poland.

Our findings mirror results published by Esser et al. (2006), that M. palustre is a species connected with alder forests and peak abundance of adults occurs in June and July.	en	Komosiński, Karol, Marczak, Dawid (2018): Four Species of Ptiliidae (Coleoptera) New to Poland.

A6228780FFDBFF94DF34394CFCBAF9FA.taxon	description	Beetles in the genus Ptinella are among the smallest members of the family (0.5 – 1.3 mm). Their yellow or brown bodies are elongated and flat with strongly shortened elytra. Nearly all species are represented by two morphological forms: forma alata with a strongly pigmented body and welldeveloped wings and eyes; and forma aptera, which lacks wings, has underdeveloped or no eyes, and shortened elytra (Besuchet 1971; Vorst 2012). Identification to species in this genus is based on the spermatheca. Four species are recorded from Poland: Ptinella aptera (Guérin-Méneville, 1839); Ptinella denticollis (Fairmaire, 1857); Ptinella limbata (Heer, 1841); and Ptinella tenella (Erichson, 1845) (Burakowski et al. 1978). However, the Catalogue of Palaearctic Coleoptera (Sörensson 2015) does not list P. tenella from Poland. We report herein two additional species, Ptinella britannica Matthews, 1858 and Ptinella microscopica (Gillmeister, 1845), for the Polish fauna.	en	Komosiński, Karol, Marczak, Dawid (2018): Four Species of Ptiliidae (Coleoptera) New to Poland.
