dct:abstract

Baranowskiella ehnstromi gen.n. and sp.n. of the featherwing beetle tribe Nanosellini (Coleoptera: Ptiliidae), the smallest beetles of all, is described from Sweden. This is the first record of the tribe from the Old World. The holomorphology of Baranowskiella is commented upon and analysed in relation to other nanoselline genera. Several characters previously not known or considered in ptilid or staphylinoid taxonomy are introduced, including the morphology of the elytral venter and metanotum. The surprising occurrence of mesocoxal mycangia and a venteroelytralmetepimeral stridulatory mechanism in Nanosellini, unique among Ptiliidae and previously unknown in Staphylinoidea, is possibly correlated with adaptation to life in bracket fungus pores.
