Notes: J and N refer to the majority and minority strand, respectively. Position numbers refer to positions on the majority strand

Procoxae with 1 spine; profemora with 3 pairs of spines on ventral surface; protibiae with 6 pairs of spines and 1 pair of apical spurs on ventral surface; tibial tympanal organs narrow, rimiform ( Fig. 2A ). Mesofemora with 4 external spines on ventral surface; ventral surface of mesotibiae with 2–4 internal, 8–9 external spines and 1 pairs of apical spurs. Postfemora with 8 external spines on ventral surface; apices of genicular lobes rounded; posttibiae with 11 internal and 8 external spines on dorsal surface, ventral surface with 4–5 internal and 7–8 external spines, apices bearing 1 pair of dorsal spurs, 1 pair of ventral subapical spurs and 2 pairs of ventral spurs.

Tegmina short, reaching posterior margin of metanotum, apices rounded ( Fig. 2E ).

Tenth abdominal tergite with basal area broad, narrowing to apical area, the subapical area curved downwards, apex obtusely rounded, dorsal surface with a longitudinal furrow along the midline, apical half which deepening and widening, the apical area slightly separated ( Fig. 2F, H, J ). Basal half of cerci stout, apical half right-angular incurved, spine-shaped; interno-dorsal margin concave ( Fig. 2J–L ). Subgenital plate with basal area broad, strongly narrowing to subapical area, apical area curved upwards and slightly widened, posterior margin straight ( Fig. 2L– M ). Styli cylindrical, inserted on lateral margin of apex of subgenital plate ( Fig. 2M ).

Female. Unknown.

Coloration. Body light brown. Frons, inner margin of scape and ventral margin of fastigium verticis black ( Fig. 2A–B ). Eyes light brown. Protibiae with blackish spots ( Fig. 2A ). Anterior margin of tegmina black ( Fig. 2E ).

Measurements (mm). Body: ♂ 27.6; pronotum: ♂ 6.8; tegmina: ♂ 4.1; postfemora: ♂ 10.2.

Material examined. Holotype: male, Sanjiangkou, Mengnuo, Longling , Yunnan, Alt. 615 m (24.41N, 99.02E), June 3, 2020, coll. by Zizhong Yang and Yunchuan Yang; DUIER.

Distribution. Yunnan (Longling).

Etymology. The new species name is from Latin “ med ” and “ cav ” referring to the male cerci, concave in the middle.

Discussion. The new species is very similar to Anelytra (Anelytra) curvata Ingrisch, 1998 , A. (Anelytra) curvata Ingrisch, 1998 , A. (Anelytra) elongata Ingrisch, 1998 A. (Anelytra) semicurvata Gorochov, 2020 and A. (Anelytra) forceps Gorochov, 2020 in male cerci, but differs from them in: face black ( Fig. 2A ); posterior margin of male tenth abdominal tergite triangular directing downwards, which split along the midline ( Fig. 2F, I ); male cerci short and right-angular curved inwards, middle area concave on dorsal margin ( Fig. 2K ); male subgenital plate long, and curved upwards, the subapical area narrowed, apical part widened ( Fig. 2L–M ).
