Type material. Holotype: male, Sanlian, Longzhou, Guangxi, 1 Aug. 2011, coll. Xun Bian. Paratype: 1 male, Nonggang, Longzhou, Guangxi, 28 Jul. 2011, 2 males, Sanlian, Longzhou, Guangxi, 2 Aug. 2011, 1 male, Damingshan, Wuming, Guangxi, 13 Aug., 2011, coll. Xun Bian.
Description. Male. Body medium. Fastigium verticis narrower than scapus, moderately sloping anteriorly, dorsally furrowed, sinuate upper edge in lateral view, separated from fastigium frontis. Pronotum with anterior margin faintly concave, posterior margin broadly rounded, three transverse sulci distinct and medial carina interrupted by second sulcus, which Y-shaped; paranota little longer than deep, anterior margin concave slightly, ventral and posterior margins moderately rounded, humeral sinus distinct. Procoxae unarmed; all femora with dorsum smoothly and longitudinal groove on venter, profemur with 4 spines on ventro-internal margin, mesofemur with 2–6 spines on ventro-external margin, profemur with 5–8 spines on ventro-external margin, 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 broad, apex narrowly 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, 2.8 mm long, 1.7 mm wide ( Fig. 10 View FIGURE 10 O); stridulatory file on underside of left tegmen concave and nearly straight, 1.55 mm long; teeth faint in basal fifth; with 148–151 teeth ( Figs. 4 View FIGURE 4 B, 11P); mirror rough oval, 2.85 mm long, 1.8 mm wide ( Fig. 10 View FIGURE 10 P). Tenth abdominal tergite with posterior margin concave; epiproct tongue-shaped, dorsally furrowed; cerci slightly short, not reaching apex of subgenital plate ( Fig. 7 View FIGURE 7 P); internal tubercle obvious at the end of basal third; strongly curved inwards in apical third; apex with a wide, slightly curved, sclerotized tooth ( Fig. 7 View FIGURE 7 R); phallus with two pairs of sclerites: lateral sclerites long, sheet-shaped, with a stout spine at posterior margin; medial sclerites short, apical margins sclerotized without any denticles ( Fig. 12 View FIGURE 12 B). Subgenital plate curved dorsally before middle; medial carina short, lateral carinae wide and long on ventral surface; basal part broad, medial area nearly equal width with apical part, posterior margin longitudinally split into two wide lobes ( Fig. 7 View FIGURE 7 Q).
Color. Body yellowish green. Pronotum with numerous brown dots on disc, with several brown dots in dorsal area and sparse small red dots in ventral area of paranota; tegmen with some large brown dots in centre of cells in lateral field; a large dark spot occupies stridulatory area of left tegmen; numerous red dots on abdominal tergites; tibial tympana with brown conchate fold and lateral black stripes on basal dorsum; cerci with dark brown apices.
Female. Unknown.
Measurements (mm). Male. Body: 16.5–17.0; body with wings: 29.5–30.5; pronotum: 3.5–3.6; tegmen length: 22.5–23.0; tegmen width: 4.2–4.4; hind wing: 26.5–27.0; profemur: 2.5–2.7; mesofemur: 4.3–4.5; postfemur: 10.1–10.5.
Etymology. The name of the new species is derived from the single apical spine on lateral sclerites of phallus.

Remarks. The new species resembles M. formosana Shiraki, 1930 , M. caligata Ingrisch, 1998 and M. bispinosa Gorochov & Kang, 2004 , but differs from them by lateral sclerites of phallus with a stout spine at posterior margin.
Distribution. China (Guangxi).
