( Figures 2 View FIGURE 2 G, 3E, 7D–F, 9K–L, 11G, 12H–K)

Type material. Holotype: male, Motuo, Xizang, 1300 m, 15 Aug. 2003, coll. Guo-Dong Ren.

Description. Male. Body large for the genus. Fastigium verticis narrower than scapus, moderately sloping anteriorly, dorsally furrowed, sinuate upper edge in lateral view, separated from fastigium frontis. Pronotum with anterior margin approximately straight, posterior margin broadly rounded, three transverse sulci distinct and medial carina interrupted by second sulcus, which Y-shaped; paranota longer than deep, anterior margin slightly concave, ventral and posterior margins moderately rounded, humeral sinus distinct. Procoxae unarmed; all femora with dorsum smoothly and longitudinal groove on venter, pro- and mesofemur without spines on ventral margins, postfemur with 4–6 spines on ventro-external margin only, all genicular lobes without spines; protibiae with internal tympanum covered by a conchate fold, external tympanum free, widened at and abruptly constricted below tympana. Tegmen faintly widened behind middle, apex broadly rounded, extending beyond apex of postfemur, Rs branching before the middle of radius, 2 branches; hind wings longer than tegmina.

Stridulatory area of left tegmen oval, 2.96 mm long, 2.0 mm wide ( Fig. 9 View FIGURE 9 K); stridulatory file on underside of left tegmen concave and curved, 1.66 mm long; teeth slightly dense in basal half; with about 160 teeth, ( Figs. 3 View FIGURE 3 E, 11G); mirror oval, 3.13 mm long, 2.06 mm wide ( Fig. 9 View FIGURE 9 L). Tenth abdominal tergite with posterior margin slightly concave; epiproct long tongue-shaped, dorsally furrowed; cerci long, surpassing apex of subgenital plate; basointernal side somewhat expanded, posteriorly narrowing ( Figs. 7 View FIGURE 7 D, 12I); moderately curved inwards, apex compressed laterally, blunt, slightly curved downwards ( Figs. 7 View FIGURE 7 F, 12H). Phallus with two pairs of sclerites: lateral sclerites long, stout, main trunk directing dorsally, apical part curved mediad and depressed on dorsum ( Fig. 12 View FIGURE 12 H); medial sclerites small, apical margin slightly concave ( Fig. 12 View FIGURE 12 K). Subgenital plate strongly curved upwards before middle; lateral carinae distinct on ventral surface; basal part broad and medial area narrow, apical part distinctly widened, posterior margin triangularly split into deviating acute lobes ( Figs. 7 View FIGURE 7 E, 12J).

Color. Body yellowish green. Pronotum with a pair of large brown dots on disc between first and second sulci, sparse brown dots on remains of the areas; a large brown spot occupies stridulatory area of left tegmen; tibial tympana with brown conchate fold and lateral black stripes on basal dorsum; cerci with dark brown apices.

Female. Unknown.

Measurements (mm). Male. Body: 17.0; body with wings: 37.0; pronotum: 5.0; tegmen length: 29.0; tegmen width: 6.5; hind wing: 34.5; profemur: 5.0; mesofemur: 7.0; postfemur: 14.5.

Etymology. The species is named for the shape of lateral sclerites of phallus.

Remarks. The new species is slightly similar to M. forcipata Ingrisch, 2011 in: male subgenital plate with posterior margin triangularly split into deviating acute lobes, but can be distinguished by following characters: apex of male cercus compressed laterally and blunt; phallus with lateral processe stout and apical part depressed on dorsum.

Distribution. China (Xizang).
