Abstract. A study of Baltic amber revealed a new fossil species the genus Bacanius LeConte, 1853. gorskii sp. nov. differs from congener described previously Eocene Rovno amber, B. kirejtshuki Sokolov and Perkovsky, in shape meso-metaventral suture, incomplete subhumeral stria, impunctate prosternal lobe (urn:lsid:zoobank.org:pub:EE9C6859-607A-4134-9037-8385601CF42F).

Macrochile hornei sp. nov. from Baltic amber (Upper Eocene) is described and illustrated. Podemacrochile gen. nov. is described with Podemacrochile baltica (Podenas, 1997) as type species. A key to the genera and species of Tanyderidae known from Baltic amber is presented.

The accuracy of model selection from decoy ensembles of protein loop conformations was explored by comparing the performance of the Samudrala-Moult all-atom statistical potential (RAPDF) and the AMBER molecular mechanics force field, including the Generalized Born/surface area solvation model. Large ensembles of consistent loop conformations, represented at atomic detail with idealized geometry...

The taxonomic placement of an enigmatic species of wasp known from two specimens in Late Cretaceous New Jersey amber is investigated through cladistic analyses of 90 morphological characters for 33 terminals ranging across non-Aculeata, non-Chrysidoidea, most subfamilies of Chrysidoidea and all genera of Plumariidae (the family to which the fossils were initially assigned), based on use of exem...

Palerasnitsynus ohlhoffigen. et sp. n. is described fromBurmese amber of late Albian (Lower Cretaceous) age. This is the first record of the family Psychomyiidae from Burmese amber, and the earliest fossil record of the family. The genus Palerasnitsynusgen. n. differs from all other known psychomyiid genera by the absence of fork III in the forewings.
