Doryctinae (Hymenoptera, Braconidae) from Baltic amber: description of a new genus and species.

A new genus and species of the braconid parasitoid subfamily Doryctinae, Palaeorhoptrocentrus kanti Belokobylskij, gen. et sp. nov., from the late Eocene Baltic amber are described and illustrated from two females. This genus is characterised by the fore wing having postfurcal position of the recurrent vein (m-cu), distally closed brachial (second subdiscal) cell, not interstitial parallel vein (CU1a), and short submedial (subbasal) cell in hind wing. Doryctomorpha tertiaria Brues, 1933 is transferred to the genus Palaeorhoptrocentrus gen. nov., P. tertiaria (Brues, 1933), comb. nov. The new genus is compared with the similar extant genera Dendrosotinus Telenga, 1941, Guaygata Marsh, 1993, and Rhoptrocentrus Marshall, 1897.
