dct:abstract

<jats:p>The braconid genus <jats:italic>Dyscritulus</jats:italic> Hincks is a small member of the subfamily Aphidiinae, distributed in Europe and Central Asia. All its species are highly specialized parasitoids of aphids of the genera <jats:italic>Drepanosiphum</jats:italic> Koch and, probably, <jats:italic>Periphyllus</jats:italic> van der Hoeven which are mostly associated with maple and sycamore trees (genus <jats:italic>Acer</jats:italic>). Upon examination of specimens from the Naturalis Biodiversity Center, Leiden, we unexpectedly noted unusual variability in morphological characters compared to other known <jats:italic>Dyscritulus</jats:italic> species. Further inspection of other material previously identified as <jats:italic>Dyscritulus planiceps</jats:italic> Marshall, 1896 revealed additional specimens with the same morphological variability. Here we describe a new species of the genus, <jats:italic>Dyscritulus europaeus</jats:italic><jats:bold>sp. nov.</jats:bold>, associated with <jats:italic>Drepanosiphum</jats:italic> aphids on <jats:italic>Acer</jats:italic>.</jats:p>
