Lochetica ramii sp. nov. – a new species of Lochetica Kriechbaumer, 1892 (Hymenoptera, Ichneumonidae, Phygadeuontinae) from Finland, with a key to world species

Two tentatively distinct morphological forms belonging to the Darwin wasp genus Lochetica Kriechbaumer, 1892 (Hymenoptera, Ichneumonidae) were found to occur in Finland, although only one species is known in Europe. The identity of the two forms were resolved by examining additional museum material, DNA barcoding and revising the relevant types. Both morphology and molecular results support the recognition of a new species, Lochetica ramii sp. nov. , from Finnish specimens – in addition to Lochetica westoni (Bridgman, 1880) already known from Finland. New host associations are given for both species and their ecology is discussed. An identification key is given to the known species of Lochetica of the world to facilitate the recognition of the new species.
