2E6187CA7B19FFE0FF0FF9D9FC52FF33.taxon	description	Description. Fig. 2 E. Head depressed dorsoventrally, slightly transverse, as wide as pronotum, rostrum almost equal to the width of antennal scape, eyes large but not convex, three ocelli nearly in one line with median one smaller, maxillary palps with distal three segments elongated and fifth segment little widened. Pronotum transverse and pubescent, almost 2 times as wide as long, lateral lobes narrow without lateral edge. Forewing short, reaching fifth abdominal tergite, five oblique veins curved with 3 longer ones jointed at base, mirror not well developed with reticulated veins instead, lateral field having 4 parallel longitudinal veins. Tympanum oval, on both inner and outer side of fore tibia with equal size, 5 – 9 proximal denticles with outer ones more than inner ones on hind tibia, and with 4 – 5 pairs of articulated spines, hind basitarsus with 5 pairs of dorsal denticles. Abdomen pubescent and cercus long, anal plate with widely rounded. Genitalia: Fig. 4, it is most similar to that of D. dendrophilus, but epiphallic lateral lobes are bifurcated apically in right angle. Moreover, the top of bifurcated lateral lobes is blunt and straight in the new species, while it is curved and acute in D. dendrophilus. Female. Similar to male. Forewing short, not as long as pronotum but touch each other in middle. Ovipositor straight (Fig. 2 F). Coloration. Totally shinning black, with hind tibia reddish brown.	en	Chen, Lin, Shen, Chu-Ze, Tian, Di, Wu, Xue, Li, Kai, He, Zhu-Qing (2019): A new species of the subgenus Duolandrevus (Eulandrevus) Kirby, 1906 from Guangxi, China (Orthoptera: Gryllidae: Landrevinae).
