Resolution of the Aleiodes seriatus (Herrich-Schäffer, 1838)-aggregate in the western Palaearctic (Hymenoptera, Braconidae, Rogadinae), with description of a new species

Abstract

Two European species are recognised and characterised within the traditional Aleiodes seriatus species concept, based initially on DNA barcoding but with supporting, although slight and sometimes unreliable, morphological differences. Aleiodes pseudoseriatus sp. nov. is described and a neotype is designated for Rogas seriatus Herrich-Schäffer, 1838. Specimens from the Russian Far East were also DNA barcoded and were found to belong to a new species distinct from the two European taxa. The two European species were found to use different lithosiine hosts.
