Anelytra (Anelytra) obtusa Liu & Bian sp. nov.

Chinese name: Ḣ尾ḎOiễ

Figures 3–4

Description. Male. Body medium. Fastigium verticis conical, robust and short, projecting forward, apex obtusely rounded. Face subrugose with numerous impressed dots ( Fig. 3A–B ). Eyes globular, protruding.

Anterior margin of pronotum with anterior margin widely rounded, posterior margin slightly concave ( Fig. 3B ); lateral lobes longer than deep, ventral margin subsinuate, anterior-ventral angle obtusely projecting, posterior-ventral angle rounded; humeral sinus shallow ( Fig. 3C ).

Procoxae with 1 spine; profemora with 3 pairs of ventral spines; ventral surface of protibiae with 4–5 internal and 6–7 external spines, apices with 1 pair of ventral spurs. Mesofemora with 0–3 internal and 3 external spines on ventral surface; mesotibiae with 6–7 ventral spines on external margin, apices with 1 pair of ventral spurs. Postfemora with 6–7 spines external margin of ventral surface; apices of genicular lobes rounded; posttibiae with 7–9 internal and 6–8 external spines on dorsal surface, ventral surface with 4 external spines, subapical area with 1 pairs of ventral spurs, apices with 2 pairs of ventral spurs and 1 pair of dorsal spurs.

Tegmina short, slightly surpassing the posterior margin of pronotum ( Fig. 3B ), reaching the middle area of first abdominal tergite.

Tenth abdominal tergite projected, basal area broad, narrow, apical half curved ventrad, split two fingered lateral lobes, which connected each other, ventral surface of the lateral lobes convex ( Fig. 3G–H ). Cerci short, not surpassing the tenth abdominal tergite, basal half stout, internal margin of base with spine, apical half curved inwards, apices obtuse ( Fig. 3G–H ). Subgenital plate with basal area broad, the lateral margins of subapical area obviously constricted, then widening to apex, posterior margin concave; apical half curved dorsad in lateral view ( Fig. 3I ). Styli located the lateral areas of posterior margin of subgenital plate.

Female. Tenth abdominal tergite projected in middle, posterior margin with 1 U-shaped excision; projections on both sides of excision slightly obtuse ( Fig. 4E ). Styli conical. Subgenital plate with basal area broad, narrowing, posterior margin straight. Ovipositor moderately upwards, dorsal and ventral margins smooth, apices acute ( Fig. 4F ).

Coloration. Body light brown. Face, inner margin of scape and ventral margin of fastigium verticis black. Apical area of femora and basal area of tibiae of all legs with black spots.

Measurements (mm). Body: ♂ 23.2–25.1, ♀ 21.9–22.5; pronotum: ♂ 7.2–7.4, ♀ 5.9–6.1; postfemora: ♂ 9.4– 10.3, ♀ 9.2–10.2; ovipositor: 9.9–10.0.

Material examined. Holotype: male, Naneng, Funing, Yunnan, 4 June , 2021, coll. by Min Li ; GXNU . Paratypes: 1 male and 3 females, the other information as holotype.

Distribution. Yunnan (Funing).

Etymology. The name of the new species is based on the obtuse apices of the male cerci, from Latin “ obtus ”.

Discussion. The new is very similar to A. (Anelytra) archaica and A. (Anelytra) superba in shape of the male cerci. It differs from them by: face black; posterior margin of male tenth abdominal tergite obviously projected and curved downwards; male cerci short, basal area with 1 small spine, apices obtuse; the lateral margins of male subgenital plate obviously constricted, posterior margin slightly concave.
