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 .
