New species of the genus Praon Haliday, 1833 (Hymenoptera: Aphidiidae) from China

Abstract

Praon genriki sp. n. and P. longistigmus sp. n. are described from Yunnan and Sichuan provinces of China. Both species are closely related to P. taisetsuzanum Takada, 1968. Praon genriki sp. n. differs from later by 18-segmented antennae, which with two last segments closely jointed, metacarpus more elongated, 1.4 times as long as pterostigma, and ovipositor sheaths stronger narrowed to the apex. Praon longistigmus sp. n. easily differs from all Praon species in structure of narrow pterostigma of the fore wings, which 8 times as long as width, 0.59 times as long as metacarpus and 0.62 times as long as radial vein. In addition to that, Praon longistigmus sp. n. differs from P. genriki sp. n. in dense pubescenсе of mesoscutum and in structure of propodeum with short keels in preapical part. A key to four species of the genus Praon with long metacarpus together with a redescription of P. taisetsuzanum are given.
