( Figures 2 View FIGURE 2 E, 4A, 7M–O, 10M–N, 11O, 12A)

Type material. Holotype: male, Nonggang, Longzhou, Guangxi, 26 Jul. 2011, coll. Xun Bian. Paratype: 2 males, Nonggang, Longzhou, Guangxi, 27–29 Jul. 2011, 2 males, Damingshan, Wuming, Guangxi, 6 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 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 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 1–3 minute spines on ventro-internal margin, mesofemur with 2–4 spines on ventro-external margin, postfemur with 4 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 nearly equal width throughout, apex 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, 4.29 mm long, 2.62 mm wide ( Fig. 10 View FIGURE 10 M); stridulatory file on underside of left tegmen concave and slightly curved, 0.98 mm long; teeth faint in basal fifth; with 88–93 teeth, ( Figs. 4 View FIGURE 4 A, 11O); mirror oval, 4.60 mm long, 2.76 mm wide ( Fig. 10 View FIGURE 10 N). Tenth abdominal tergite with posterior margin slightly concave; epiproct short, tongue-shaped, dorsally furrowed; cerci long, but not reaching apex of subgenital plate ( Fig. 7 View FIGURE 7 M), baso-internal side expanded, posteriorly narrowing; strongly curved inwards in apical quarter; apex compressed laterally, acute ( Fig. 7 View FIGURE 7 O); phallus with two pair of sclerites: lateral sclerites bent inwards, basal part wide, distal part rather narrow; medial sclerites small, apex rounded and denticulated ( Fig. 12 View FIGURE 12 A). Subgenital plate curved dorsally before middle; basal part broad, medial area nearly equal width with apical part, posterior margin longitudinally split into two wide lobes ( Fig. 7 View FIGURE 7 N).

Color. Body yellowish green. Pronotum with brown dots on disc and in paranota; a large brown 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: 13.0–13.5; body with wings: 25.5–26.5; pronotum: 3.1–3.3; tegmen length: 18.5–20.0; tegmen width: 3.1–3.3; hind wing: 23.5–24.5; profemur: 2.8–3.0; mesofemur: 4.3–5.2; postfemur: 9.5–10.0.

Etymology. The species is derived from Latin ‘amplecta’ = to embrace; it refers to lateral sclerites of phallus with distal part long and bent inwards.

Remarks. The new species differs from known species of the genus Mirollia by the shape of characteristic lateral sclerites of phallus.

Distribution. China (Guangxi).
