Abstract
New data concerning the occurrence of pleasing fungus beetles (Coleoptera: Erotylidae) in Poland are given, with a focus on rare and difficult to identify Central European taxa. Cryptophilus cf. integer (Heer) (Cryptophilinae) is reported from the Polish territory for the first time based on adult and larval specimens collected in the Wielkopolska-Kujawy Lowland. Identification problems concerning species of Cryptophilus introduced to Europe are discussed. Triplax carpathica Reitter (Erotylinae) is recorded from the Białowieża Primeval Forest, which is the first known non-Carpathian finding of this species, located in the close proximity of the Polish-Belarussian UNESCO World Heritage Site “Białowieża Forest”. Discussion of Triplax carpathica being conspecific with Siberian Triplax rufiventris Gebler is provided. New Polish localities of several other Erotylidae are reported, and an updated key to Central European species of Triplax is given. The Triplax key is supplemented with dorsal and ventral habitus images of all treated Triplax species. One of the rarest Central European erotyline species Combocerus glaber (Schaller) is recorded from xerothermic grasslands in North-West Poland.
Highlights
The systematics of pleasing fungus beetles (Erotylidae) has undergone significant changes within the past decade, and according to the currently accepted classification (Węgrzynowicz 2007) all species hitherto known to occur in Poland belong to the subfamily Erotylinae
Among the beetles recently collected in the Białowieża Primeval Forest, two specimens possibly belonging to T. carpathica were found
It is plausible that Triplax carpathica is another species with primarily Eastern Palearctic distribution that extends westwards to the Białowieża Primeval Forest in Central Europe
