Lathrolestes caudatus (Thomson, 1883) View in CoL

Lathrolestus caudatus, Thomson, 1883 , type lost.

Lathrolestus pleuralis Thomson, 1883 . ex. syn.; Hinz, 1996.

Lathrolestus nasoni Davis, 1897 , Holotype, male, Algonquin, IL, (ANSP) syn. nov. Lathrolestus similis Davis, 1897 , Holotype, female, Colorado, (ANSP); Barron, 1994; Aubert, 2000.

In regards its main character states, the holotype of L. nasoni Davis, 1897 is fully similar to L. caudatus (Thomson, 1883) . Consequently, L. nasoni Davis, 1897 is proposed as a new junior synonym for L. caudatus (Thomson, 1883) . Ovipositors of both these taxa are long, slightly curved up, with apical teeth. There is a slight difference in coloration in Nearctic and Palearctic specimens: Nearctic individuals have reddish-brown clypeus; propodeum varying from black to reddish-brown; Palearctic specimens with black clypeus and propodeum. This species was recorded as parasitoid of Ardis brunniventris (Hartig, 1837) on Rosa rugosa View in CoL in Europe ( Evenhuis, 1973).
