description: 20. Mirollia acutilobata sp. nov.
(Figures 1 F, 3J, 6G–I, 9M–N, 11L, 12C–E)
Type material. Holotype: male, Jiulianshan, Longnan, Jiangxi, 23 Jul. 2008, coll. Fu-Ming Shi. Paratype: 4 males, same data as in holotype.
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 6 minute spines on ventro-internal margin, mesofemur with 6 spines on ventro-external margin, and postfemur with 6–9 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. Tegmina broad, 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 long oval, 3.28 mm long, 1.67 mm wide (Fig. 9 M); stridulatory file on underside of left tegmen concave and nearly straight, 1.42 mm long; teeth dense in basal fifth; with 52–54 teeth, (Figs. 3 J, 11L); mirror long oval, 3.48 mm long, 1.88 mm wide (Fig. 9 N). Tenth abdominal tergite with posterior margin concave; epiproct small, triangular-shaped, dorsally furrowed; cerci slightly long, but not reaching apex of subgenital plate (Fig. 6 G); baso-internal side somewhat expanded, posteriorly narrowing; strongly curved inwards in about apical third and then slightly recurved up-outwards; apex with a stout apical spine (Fig s. 6I, 12C); phallus with two pairs of sclerites: lateral sclerites longer, apical part slightly curved upwards, apex acute (Fig. 12 D), medial sclerites small, apex divided into narrow dorsal lobe denticulated and wider ventral lobe (Fig. 12 E). Subgenital plate curved dorsally before middle; lateral carinae distinct on ventral surface; basal part broad, medial area nearly equal width with apical part, posterior margin longitudinally split into two wide lobes (Fig. 6 H).
Color. Body yellowish green. Pronotum with numerous brown dots on disc and in paranota; tegmen with some large black dots in centre of cells in lateral field, along posterior margin with a regular band of black dots, a rather large brown spot occupies stridulatory area of left tegmen; numerous red dots on abdominal tergites and lateral sides of femora; tibial tympana with lateral black stripes on basal dorsum; cerci with dark brown apices.
Female. Unknown.
Measurements (mm). Male. Body: 15.0–15.5; body with wings: 31.0–32.5; pronotum: 3.8–4.0; tegmen length: 23.0–24.0; tegmen width: 3.9–4.0; hind wing: 28.5–29.0; profemur: 3.3–3.5; mesofemur: 4.8–4.9; postfemur: 11.2–11.5.
Etymology. The species is named for the shape of lateral sclerite of phallus.
Remarks. The new species resembles other Mirollia species in appearance, but is distinctly distinguished by the shape of stridulatory file and lateral sclerites of phallus.
Distribution. China (Jiangxi).
