Abstract

Arcanys rostratus Chemyreva gen. et sp. nov. is described from the Eocene Rovno amber in the tribe Betylini (subfamily Ambositrinae) as the first member of this tribe discovered in Europe – in amber and in recent fauna. This new genus differs from other genera of the Ambositrinae by a combination of such features as: the pleurostomal carinae positioned at right angles to each other, the absence of notauli, the propodeum with strongly elevated plicae but without median carina and carina along posterior margin, the fore wings with short marginal and stigmal veins, and the base of T2 deeply arcuated but without notches and elongate grooves. The distribution of the subfamily Ambositrinae is discussed.
