A description of a new genus and species of braconid, Archephedrus stolamissus, from Early Cretaceous (Albian) amber from Moraza-Peñacerrada I (Spain) is here provided. This is the first fossil Aphidiinae described in Cretaceous amber. The fossil has some typical characters of the subfamily but possesses a unique assemblage of characters among aphidiines, such as a fairly robust abdomen, with a more pronounced articulation between the first and second, instead of the second and third, metasomal segments, as well as several wing venational traits. The distribution of this and other aphidiine fossils, as well as their putative phylogenetic placement as …

The Agathidinae (Insecta: Hymenoptera: Braconidae) Of Sakhalin And The Kuril Islands, Michael J. Sharkey, Daniel J. Bennett

Faculty Publications

Recent collecting on Sakhalin and the Kuril Islands, during joint U.S., Russian, and Japanese surveys known as the International Kuril and Sakhalin Island Projects, has resulted in range extensions for 10 species in the braconid subfamily Agathidinae and 17 new taxon records for islands in the Kuril chain, Sakhalin, and Moneron. In addition to a check list of the 19 species of Agathidinae presently known to occur on Sakhalin and the Kuril Islands, a generic key and updated keys to the species of Agathis Latreille, 1804, Bassus Fabricius, 1804, and Coccygidium Saussure, 1892 are provided for the region at large …
