Abstract

A new genus and species of the braconid parasitoid subfamily Doryctinae, Eocenhecabolus kotenkoigen. et sp. nov., from the late Eocene Rovno amber are described and illustrated. Eocenhecabolusgen. nov. is the first unambiguously extinct Doryctinae genus. This genus is described from the male and characterised by the followings features: in the fore wing by the postfurcal position of the recurrent vein (m-cu) relatively to the first radiomedial vein (2-SR), and a distally open brachial (second subdiscal) cell; in the hind wing by the presence of the elementary stigma-like enlargement on the distal half of the costal (1-SC+R) vein. The different types of stigma-like enlargements found in the hind wings of males in the subfamily Doryctinae are discussed.
