Revision of the Western Palaearctic species of the genus Dinotrema Foerster, 1862 (Hymenoptera, Braconidae, Alysiinae).

Abstract

The first comprehensive revision of the Western Palaearctic species of the genus Dinotrema Foerster, 1862 is provided. 174 species of this genus are redescribed and illustrated. Ten species are described as new, viz, D. acompressum sp. nov., D. cahitum sp. nov., D. collybiae sp. nov., D. digitatum sp. nov., D. glabrideum sp. nov., D. helote sp. nov., D. lepiotae sp. nov., D. norwegicum sp. nov., D. oxybellum sp. nov. and D. torpi sp. nov. The following new combinations are suggested: Dinotrema adventum (Fischer), comb. nov., D. aurelianum (Fischer), comb. nov., D. cetiusmonte (Fischer), comb. nov., D. converginerve (Fischer), comb. nov., D. intermissum (Fischer), comb. nov., D. leptocorne (Fischer), comb. nov., D. longicarinatum (Fischer), comb. nov., and D. thurnense (Fischer), comb. nov. The following names are synonymised: Dinotrema naeviformis (Fischer) with D. costulatum (Thomson), Dinotrema aequale Tobias with D. tarbagataicum Tobias, D. alua (Stelfox et Graham) with D. tauricum (Telenga), D. isometricum (Fischer) with D. cruciatum (Fischer), D. isosoma (Fischer) with D. cruciforme (Fischer), and D. ovalisignum (Fischer) with D. catharinae (Fischer) (syn. nov.). A key to all Western Palaearctic species of Dinotrema is provided for the first time.
