Abstract:

In this paper, a new genus and species of the pionini is reported, Type specimens are kept in the Institute of Zoology, Academia Sinica.Celata Wang gen.nov.This genus is similar to the genera Glyptorhaes Thomson and Rhorus Foerster, but can be separated from the former by :inner eye margins straight not convergent ventrad; the outer surface of minute smooth or with minute punctures; tarsal claws conspicuously pectinate and from the latter by :clypeus separated from face by a groove, its apical margin being weak arc, the upper tooth of mandible shorter than its lower tooth, ovipositor sheath about as long as apical depth of abdomen, and may be differed from both species by :propodeum without transcerse carinae and areace, nervulus opposite basal vein.Nervellus curvate at the lower part.Celata populus Wang, sp.nov.Lenghth of front wing :Female 3.5~ 4.0mm, male 3.0 ~ 3.5mm.The major characteristics as follows :Inner eye marjins straight, not convergent ventrad; the center of face clearly conex; Clypeus wider, about 3 times the length, its apical margin being weak arched, the outer surface of mandible smooth or with minute punctures, its upper tooth shorter than lower one, mesoscutum even, notaulus short and weak, scutellum convex; upper end of prepectal carina reaching to front edge of mesopleurum.Propodeum without transverse carinae and areae, the both sides of its apex with a short longitudina carina, between them having weak and arcuate sculptures.Forewing areolet present, nervulus opposite basal vein; hindwing nervellus curvate at very low part.Tarsal claws pectinate.The tergite 1 about 1.35 times as long as its apical width, glymma present, its median dorsal carinae absent and dorsolateral curina usually complete at the front before spiracle, tergite 2 with small and weak punctures; Ovipositor sheath about equal to the apical depth of gasterHolotype ♀, Shanghe County, Shandong Province, 6.V.1993;paratypes 10 ♀♀20 ♂♂, time and locatily as above.Host :Messa taianensis Xiao et Zhou.
