description: Mongoliana bistriata sp. nov.
(Figs 1–3 & 7–20)
Diagnosis. The new species is similar to M. serrata Che, Wang et Chou (Figs 42–44), but differs from the latter in tegmina and male genitalia (features of M. serrata in parentheses): transverse fascia of tegmina interrupted in middle (transverse fascia continuous, not interrupted in middle); apical margin of male anal tube deeply concave (apical margin distinctly convex); lateral lobes of phallobase long and separated from dorsal lobe at its apical 1/3, apical margin subacute, serrate on dorsal side; aedeagus with paired elongate hooks both deriving from the right side and close to each other (lateral lobes of phallobase short and separated from dorsal lobe near apex, apical margin blunt, serrated from dorso-caudally to ventrally, aedeagus with paired hooks both deriving from midline in ventral view and situated far away from each other).
Description. Male length (N=1) (including tegmina): 4.2 mm, length of tegmina: 3.7 mm; female length (N=1) (including tegmina): 4.5 mm, length of tegmina: 4.0 mm.
Coloration. Body fulvous. Frons reddish in middle. Pronotum and mesonotum fuscous, pronotum with small tubercles along inner side of anterior margin. Tegmina with a short black stripe at basal 1/4, an interrupted black fascia in middle and three big and several small black blotches at apical part. Hind wings light brown, veins dark fulvous. Leg with hind femur and tip of spines black (Figs 1–3).
Head and thorax. Vertex approximately 1.5 times wider than long in midline (Fig. 1). Frons smooth, approximately 1.1 times longer than its maximum width, 2.1 times wider at widest part than upper margin (Fig. 3). Frontoclypeal suture straight (Fig. 3). Pronotum with six small tubercles laterally (Fig. 1). Mesonotum about 2.2 times wider at widest part than long in midline (Fig. 1). Tegmina approximately twice as long as wide at widest part. Hind wings semitransparent, about 0.8 times length of tegmina, veins ScP+R (2), MP (4), CuA (2), CuP (1), Pcu (1); ScP+R branched in apical half, with three transverse veinlets between ScP+R and costal margin, between radius and median posterior with several oblong cells, median posterior firstly furcates beyond wing middle, and again in apical part of the wing, MP4 and CuA1 curvilinear, cubitus anterior furcates before wing middle, and again branched in apical part of wings (Fig. 7). Metatibiotarsal formula 2+6/7/2.
Male terminalia. Anal tube with apical margin deeply concave in dorsal view, lateroapical angles strongly prominent (Fig. 9). Anal column located at middle (Fig. 9). Pygofer in profile with posterior margin strongly produced near middle, anterior margin slightly concave in upper half, ventral margin relatively straight, dorsal margin oblique (Fig. 8). Aedeagus asymmetrical, with a pair of curved processes deriving from basal half at right side, the longer one near middle, circled at basal third and directed caudad at apex, the shorter one shifted more basad, circled in middle and directed caudad apically; lateral lobes of phallobase separated from dorsal lobe at apical 1/3, blade-shaped, dorsal margin dentate; ventral lobe gradually narrowing from middle to apex, apical margin slightly concave medially (Figs 11–13). Genital styles with hind margin strongly concave, caudo-ventral angle rounded, dorsal margin has a large obtusely rounded process at middle (Fig. 8). Capitulum of genital style short and narrow, with a large lateral tooth (Fig. 10).
Female terminalia. Anal tube with apical margin arcuately convex (Fig. 14). Anal column located in basal half. Gonoplacs nearly rectangular in lateral view, disc moderately elevated, fused at base and fork slightly sclerotized (Figs 15 & 16). Proximal part of posterior connective lamina of gonapophyses IX strongly convex in lateral view; median field membranous with wide single lobe, apical margin slightly emarginate at middle, distal part of posterior connective lamina with a pair of small spines (Figs 17 & 18). Gonospiculum bridge elongate in lateral view (Fig. 18). Anterior connective laminae of gonapophysis VIII almost quadrate, with three small teeth in apical group and two parallel teeth in lateral group (Fig. 19). Sternum VII with posterior margin distinctly convex at middle (Fig. 20).
Material examined. Holotype: male, China, Guizhou Province, Wuyanqiao, Libo County, Maolan National Nature Reserve, 29 July 2012, coll. Lifang Zheng. Paratype: 1 female, same data as holotype (NWAFU).
Etymology. The specific epithet “ bistriata ” refers to two dark fasciae of the tegmina.
Distribution. China (Guizhou) (Fig. 81).
