description: Mongoliana latistriata sp. nov.
(Figs 4–6 & 27–44)
Diagnosis. This new species is similar to M. bistriata sp. nov., but differs from the latter in tegmen and male genitalia (features of M. bistriata in parentheses): tegmina with the fascia relatively broad and continuous at middle and irregular blotches numerous from base to apex (fascia relatively narrow and interrupted at middle, blotches sparse in distal 1/3); apical margin of anal tube almost straight in middle (apical margin semicircularly concave); lateral lobes of phallobase with serrate dorsal margin concave, aedeagus with a pair of flexuous processes deriving from basal part at right side and middle line (lateral lobes of phallobase with serrate dorsal margin relatively straight, aedeagus with paired elongate processes only on the right side).
Description. Male length (N=7) (including tegmina): 4.2–4.6 mm, length of tegmina: 3.7–4.1mm; female length (N=2) (including tegmina): 4.5–4.7 mm, length of tegmina: 4.0– 4.2 mm.
Coloration. Body ochraceous. Vertex dark fulvous. Frons pale fusco-rufous, lateral margins dark fulvous, with a large black blotch in middle. Clypeus pale yellow, disc strongly elevated, below frontoclypeal suture with oblique stripes laterally and two small pale testaceous depressions in middle. Rostrum pale brown. Pronotum dark brown, with grayish-white small tubercles, anterior and posterior margins black in middle. Mesonotum fuscous. Tegmina pale brown, scattered with black maculae, the narrow fascia at base and wide transverse band in apical third black. Hind wings light brown, veins dark fulvous. Leg pale brown (Figs 4–6).
Head and thorax. Vertex with median carina thick, anterior margin arcuately convex, posterior margin angularly concave, about 2.0 times wider at base than long in midline (Fig. 6). Frons densely wrinkled, approximately 1.1 times longer than wide at widest part (Fig. 4). Frontoclypeal suture arcuate (Fig. 4). Mesonotum about 2.0 times wider at widest part than long in midline (Fig. 6). Tegmina about 2.0 times longer than maximum width. Hind wings subtranslucent, about 0.8 times length of tegmina, veins ScP+R (2), MP (2), CuA (2), CuP (1), Pcu (1); ScP+R branched in apical part, with three transverse veinlets between ScP+R and costal margin, median posterior furcates before wing middle, cubitus anterior furcates at apical part of wing, between median and cubitus anterior with one secondary vein forming a small trianglular cell (Fig. 27). Metatibiotarsal formula 2+6/7/2.
Male terminalia. Anal tube with apical margin concave in dorsal view, lateroapical angles strongly protuberant (Fig. 30). Anal column located at middle (Fig. 30). Pygofer in lateral view with posterior margin obtusely convex near middle, concave at basal 1/3 (Fig. 29). Aedeagus asymmetrical, with pair of ventral hooks at basal half, the right one bent to left, and the left one bent to right, tips directed towards to each other; lateral lobes narrow and long in apical half, dorsal margin dentate; ventral lobe gradually expanded from middle to apex, apical margin slightly concave medially (Figs 31–33). Genital style with hind margin slightly concave submedially, caudo-ventral angle rounded, dorsal margin with a large subquadrate process at middle (Fig. 29). Capitulum of genital style nearly rectangular, with large lateral tooth (Fig. 28).
Material examined. Holotype: male, China, Hunan Province, Zhangjiajie City, Sangzhi County, Badagongshan National Nature Reserve, 700 m, 31 July 2016, coll. Lifang Zheng (NWAFU). Paratypes: 2 males, same data as holotype (NWAFU); 1 male, China, Hunan Province, Changde City, Taoyuan County, Wuyunjie National Nature Reserve, 12 August 2013, 240 m, coll. Lifang Zheng (NWAFU); 1 female, China, Hunan Province, Changde City, Shimen County, Huping Mountain, 350 m, 17 August 2007, coll. Lingfei Peng (NWAFU); 1 male and 1 female, China, Hunan Province, Changde City, Shimen County, Huping Mountain, 17 August 2004, coll. Jiliang Wang (HBU); 2 males, Hunan Province, Zhangjiajie City, Zhangjiajie National Forest Park, 13 August 2004, coll. Jiliang Wang (HBU).
Etymology. The specific epithet is derived from Latin word “ latus ” and “ striatus ”, referring to the wide fascia in the middle of the tegmina.
Distribution. China (Hunan) (Fig. 81).
Notes. The specimens used for erecting M. latistriata sp. nov. have the aedeagus bearing variably shaped ventral hooks, these differences are here considered to represent intraspecific variation and noted as below:
A. Specimen from Badagongshan National Nature Reserve of Zhangjiajie City (Figs 34 & 35), from Wuyunjie National Nature Reserve of Changde City (Fig. 36) and from Zhangjiajie National Forest Park of Zhangjiajie City (Fig. 41) with the ventral hooks curved semicircularly, the same feature as that of the holotype.
B. Specimen from Huping Mountain of Changde City, the ventral hooks with the upper one curved caudad at base and then bent cephalad, the lower one circled at base and bent caudad apically (as shown in Figs 37 & 38).
C. Specimen from Zhangjiajie National Forest Park of Zhangjiajie City, the ventral hooks with the upper one directed caudad and bent cephalad at basal 1/3, the lower one curved at base and thence directed to the right side (as shown in Figs 39 & 40).
