FIGURE 5. Nigrimacula quadrinotata (Bey-Bienko, 1971) com. nov. , holotype: A–B. dorsal view; C–D, F. lateral view; E. ventral view; G. ovipositor in lateral view; F, G. from Eades et al. (2016). Description. Male. Head. Fastigium verticis conical, dorsal surface with a median sulcus ( Fig. 4 A). Eyes nearly global, protruding forwards. Apical segment of maxillary palpi slightly longer than subapical one, apex inflated. Thorax. Pronotum with anterior margin almost straight, posterior margin narrowly rounded ( Fig. 4 A); lateral lobe longer than high, ventral margin undulating, posterior margin with distinct humeral sinus ( Fig. 4 B). Legs. All femora unarmed on ventral surface. Procoxae with a short spine. Pro- and mesotibiae with 4 pairs of minute spines and 1 pair of apical spines on ventral surface. Posttibiae with 20–22 inner and 19–21 outer spines on dorsal surface, ventral surface with 4–8 minute outer spines, apices with 1 pair of dorsal spurs and 2 pairs of ventral spurs. Wings. Tegmina reaching apices of posttibiae; hind wings slightly longer than tegmina. Abdomen. Posterior margin of tenth abdominal tergite arched concave ( Fig. 4 C, D). Cerci stout, apical area concave forwards, forming a deep cavity ( Fig. 4 F); dorsal margin of apical area with 1 lamellar process, its apex with 9 teeth forming 2 groups ( Fig. 4 F–H); 1 cylindrical process connecting the lamellar process with 7 apical teeth ( Fig. 4 G); internal margin with 1 spatulate process, its apex with 15 teeth ( Fig. 4 E); the ventral margin of the spatulate process followling an olique, lamellar lobe with 7 apical teeth ( Fig. 4 F). Subgenital plate longer than broad, hexagonal, basal margin almost straight, lateral margins of basal half parallel, apical half slightly narrowing, posterior margin almost straight; styli short and stout conical, located on apices of lateral margins ( Fig. 4 H). Coloration. Body yellowish green (probably light green when alive). Eyes brown. Fastigium verticis black brown, occiput with 1 longitudinal light brown stripe in the middle, which extending to pronotal disc, metazona lighter than other area; the lateral margins of the median stripe with 1 yellow stripe separately; centre of posterior margin brown ( Fig. 4 A, I). Measurements (mm). BL: ♂ 9.495–10.562, ♀ 10.932; PL: ♂ 3.338–3.487, ♀ 3.013; PFL: ♂ 7.715–7.958, ♀ 7.925; TL: ♂ 16.147–17.070, ♀ 17.121; Ov: 8.716. Distribution. China (Yunnan); Burma ( Myanmar ). Remarks. The original description of the species is based on a single female specimen. Except for Myanmar , the distribution record of the species was once expanded to Sichuan and Xizang ( Jin & Xia, 1994 ; Liu & Jin, 1994 ). Wang et al. (2015) recorded that the specimens from Xizang (examined specimens in their study is “5 ♀ , Motuo County, Xizang province, alt. 970–1570 m , 1979. IX.10–1980 . VIII.14 , leg. JIN Gen-Tao & WU Jian-Yi; 2 ♀ , Motuo County, Xizang province, alt. 1000 m , 2010. VIII. 6–8 , leg. BI Wen-Xuan; 1 ♂ 2 ♀ , Beibeng Village, Motuo County, Xizang province, alt. 850–1200 m , 1983. IV.9–V. 18 , leg. HAN Yin-Heng.”) are members of Xiphidiopsis quadrinotata , and the specimen (examined specimen in their study is “1 ♀ , Erlang Mountain, Tianquan County, Sichuan province, alt. 900 m , 2010. IX.5 , leg. BI Wen-Xuan”) from Sichuan belongs to Meconemopsis paraquadrinotata Wang, Liu & Li, 2015 . After our study, we deem that the specimens from Mêdog, Xizang should be identified as Nigrimacula xizangensis ( Jiao & Shi, 2013 ) , as deforming the specimen from Sichuan is not succesfully identified, and Nigrimacula quadrinotata ( Bey-Bienko, 1971 ) lives only in Yunnan Province in China .
