Fagineura crenativora Vikberg & Zinovjev, 2000.

Diagnosis.

Compared with the diagnosis of Liu et al. (2019), we present the following changes: Medium-sized; clypeus and labrum yellowish white to yellow; clypeus with broad and moderately deep (0.3-0.5) emargination apically; mandibles symmetrical; malar space shorter than diameter of median ocellus, and in most species not exceeding 0.5 × of diameter of median ocellus; postocellar area more than 2.0 × as wide as long; antenna usually shorter than thorax and abdomen together; posterior part of mesopleural katepimeron covered with hairs; distance between cenchri as long as or shorter than breadth of a cenchrus; forewing without radial cross-vein; the costa of forewing less dilated than in Pristiphora ; petiole of anal cell of hindwing of F. quercivora Togashi, 2006 short than cu-a, and the other 5 species longer than cu-a; claws bifid, inner tooth large; sawsheath short; annular suture 1 with setae band; the longest setae bands of lancet is at least 0.5 × length of annulus; cypsella of basal serrulae absent, apically short and with emargination; tangium of lancet with campaniform sensilla in most species; except for F. quercivora Togashi, 2006 we unknown, the radix of F. xanthosoma Liu, Li & Wei, 2019 shorter than lamnium, and the other 4 species longer than or as long as lamnium.

Remarks.

Shinohara et al. (2000) provided the differences between Fagineura and Nematus , but based on all species of Fagineura , it differs from Nematus in annular suture 1 of lancet with setae band; less derived shape of the mandibles; malar space narrower than the diameter of the median ocellus; katepimeron of the mesopleuron with hairs; having campaniform sensilla on the tangium except for F. flactoserrula only one or none; the apically emarginate sawsheath except for F. xanthosoma .
