THE FOSSIL PELECINIDS PELECINOPTERON BRUES AND ISCOPINUS KOZLOV (HYMENOPTERA, PROCTOTRUPOIDEA, PELECINIDAE)

The status of the two described genera of fossil Pelecinidae is review ed. The type material of Pelecinopteron tubuliforme Brues has apparent ly been lost or destroyed. A single partial male specimen from Paleoce ne amber is known. On the basis of this specimen and the illustrations in the original description, the placement of Pelecinopteron within t he Pelecinidae is corroborated. Synapomorphies uniting the two are an extremely elongate, tubular female metasoma; basal segment of the hind tarsus shorter than second segment; hind tibiae of female swollen; Rs with two long branches. The association of the lower Cretaceous speci es Iscopinus baissicus Kozlov with Pelecinidae is not supported. The p urported branch of Rs, is interpreted as the crossvein r-m, a plesiomo rphic feature. The subfamily Iscopininae is removed from Pelecinidae a nd considered as the family Iscopinidae new status within Proctotrupoi dea s. str.
