Diagnosis. This species can be recognized by the following combination of characters: lower frons ( Fig. 9 ) with medial longitudinal narrow groove and coarse punctures; pronotum latero-ventrally ( Fig. 12 ) with irregular areolate sculpture; propodeal areola ( Fig. 11 ) trapezoidal, strongly convergent posteriorly; subposterior area of T1 close to middle and ( Fig. 14 ) medially with one transverse row of short longitudinal striae; tegula 2.1× longer than wide ( Fig. 13 ); inner face of hind basitarsus medially with longitudinal groove.

Description. Female ( Fig. 8 ). Body length 8.8–9.1 mm, forewing length 5.1–5.6 mm.

Color. Body almost black, with pale brown setae; mandible and flagellum reddish brown ( Fig. 9 ); upper part of tegula ( Fig. 13 ) dark brown and lower part brown; pterostigma, veins, tarsi and posterior of pygidium ( Fig. 15 ) brown; wings ( Fig. 8 ) infuscate.

Head. Mandible ( Fig. 9 ) without distinct medial transverse groove and preapical denticle, atmost with obsolete intermittent impressed line; clypeus ( Fig. 9 ) basally with coarse punctures and apically smooth, apex medially truncated; W: OW: L: IOD=10: 5.4: 6: 6.9; OOD: POD: Od=10: 7.8: 3.6; AOD: WAS: IAD: CL: CAW=10: 6: 3.6: 5.8: 6.2; lower frons ( Fig. 9 ) with medial longitudinal narrow groove and coarse punctures, upper frons with relatively sparser punctures; vertex ( Fig. 10 ) with sparse punctures, interspaces smooth; close to occipital carina with sparse punctures mixed with dense minute ones.

Mesosoma . Pronotal anterior carina incomplete, medially weak, anterior half of pronotum with dense punctures, posterior half impunctate; pronotum latero-ventrally ( Fig. 12 ) with irregular areolate sculpture; mesoscutum medially with dense punctures, laterally with sparser ones, anterior medial groove separated from notaulus; mesopleuron ( Fig. 12 ) anteriorly with dense big punctures, elsewhere with a few scattered and small punctures; along margins of mesoscutellum ( Fig. 11 ) with big and dense punctures; metanotum posteriorly with a few big punctures mixed with some minute ones; horizontal area of propodeal dorsal face coriaceous ( Fig. 11 ), oblique area densely pitted and with submarginal carina, posteriorly with short longitudinal striae connecting transverse carina; propodeal areola ( Fig. 11 ) trapezoidal, strongly convergent posteriorly, APWL=4.5: 2.1: 8.2, medial longitudinal carina reaching posterior 3/5 of areola; lateral surface of propodeum dorsally with dense long oblique wrinkles, ventrally with a few minute punctures; posterior surface of propodeum granulate, without short medial longitudinal carina; tegula ( Fig. 13 ) 2.1× longer than wide, posterior margin without transverse impressed line; second intercubital vein of forewing ( Fig. 8 ) strongly sinuous; fore and mid tibiae with one spur apically, hind tibia with 2 spurs apically; inner face of hind basitarsus medially with longitudinal groove.

Metasoma. Anterior half of T1 ( Figs 8, 14 ) with deep and dense punctures; subposterior area of T1 close to middle and with one transverse row of short longitudinal striae, posterior half impunctate; S1 with dense minute punctures, with posterolateral groove and reaching the anterior apex; T2 antero-laterally with costate transverse depression ( Fig. 14 ), medially obsolete; T2 with irregularly dense punctures, postero-medially smooth, with sparse punctures; S2–S5 with irregularly dense punctures; pygidium ( Fig. 15 ) anteriorly and medially with dense punctures, posteriorly coriaceous.

Male. Unknown.

Distribution. China (Yunnan).

Etymology. The specific name longistria is derived from the two latin words: long (= longitudinal) + stria (= striae), referring to subposterior area of T1 close to middle and medially with one transverse row of short longitudinal striae.
