Xiphidiopsis quadrinotata Bey-Bienko, 1971. Entomological Review, 50: 475. Meconemopsis quadrinotata Wang et al., 2015. Zootaxa, 3941(4): 523.
Location of type specimen: British Natural History Museum, London, UK.
Specimens examined. Holotype: female, Nam Tamal Valley, Upper Burma, Myanmar, 24 July, 1938, coll. by R. Kaulback. Other specimens: 2 males, Bangda, Ruili, Yunnan, China, 8 September, 2015, coll. by Yutang Wang; 1 male, Ruili, Yunnan, China, 20 September, 2015, coll. by Yutang Wang; 1 female, Mangdong, Lianghe, Yunnan, China, 20 September, 2015, coll. by Yutang Wang.
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.
