( Fig. 1 View FIGURE 1 )

Type material. Holotype: China: 1 ♂, labeled ‘ CHINA: Yunnan Prov., Baoshan City (保山市), Mangkuan Town (芒宽 乡), Baihualing (百花岭), 25.16.39 N, 98.47.55 E, alt. 1200 m, 22.iv.2013, Dai, Peng & Song leg.’; HOLOTYPE [red], Zyras baihuamontis, Yan & Li det. 2015, ( SNUC); Paratype: 1 ♀, same label as above-mentioned, PARATYPE [yellow], Zyras baihuamontis, Yan & Li det. 2015, ( SNUC).

Description. Body length: 9.02–9.22 mm. Coloration: head, elytra, blackish; pronotum darker reddish-brown; abdomen blackish with the posterior margins of the segments reddish-brown; legs and antennae reddish to reddishbrown.

Head ( Fig. 1 View FIGURE 1 A) approximately as long as wide or weakly oblong; punctation sparse on head; eyes large and bulging, more than twice as long as postocular region in dorsal view; Antennae not distinctly flattened and short, barely reaching posterior margin of pronotum when directed caudad; antennomere III distinctly dilated apically, nearly twice as long as wide; Pronotum ( Fig. 1 View FIGURE 1 A) squared, approximately 1.38 times as wide as head and 1.09 times as wide as long; punctation distinctly denser and coarser than that of head. Elytra dilated posteriad, at posterior margin approximately 1.33 times as wide, and at suture 0.86 times as long as pronotum; punctation conspicuously dense and defined, but finer than that of pronotum. Hind wings fully developed. Abdomen ( Fig. 1 View FIGURE 1 A) approximately as wide as elytra at posterior margin, widest at segment IV; microsculpture present, but mostly shallow; punctation fine and moderately dense; tergites IV and VII with pronounced sexual dimorphism.

Male: tergite IV ( Fig. 1 View FIGURE 1 A) conspicuously modified, posterior margin, and on either side with long and acute process; tergite VII ( Fig. 1 View FIGURE 1 A) at posterior margin with pronounced tubercle; posterior margin of tergite VIII in the middle slightly truncated. aedeagus ( Figs. 1 View FIGURE 1 G, 1H, 1I) with conspicuous processes.

Female: tergites IV, V, and VII unmodified; posterior margin of tergite VIII in the middle concaved; spermatheca as in Fig. 1 View FIGURE 1 F.

Measurements. BL: 9.01–9.22; FBL: 4.00–4.17; HW: 0.99–1.35; PL: 1.46–1.49; PW: 1.55–1.66; EL: 1.27–1.29; EW: 2.33–2.47.

Distribution. China: Yunnan.

Etymology. The specific epithet derives from the name of the type locality.

Comment. The new species is similar to Zyras ( Termidonia) longwangmontis Pace, 1998 by sharing a similar general appearance. The species is readily distinguished from Z. ( T.) longwangmontis by darker coloration of the pronotum (in Z. ( T.) longwangmontis reddish), by different modifications of the male abdomen (in Z. ( T.) longwangmontis the processes on tergite IV shorter and posterior margin of tergite V in the middle produced), by slender and curved median aedeagus in lateral view, and by different shape of apico-lateral processes of median lobe of the aedeagus (in Z. ( T.) longwangmontis curved at apex in ventral view).
