description: <i>Kamimuria flavimacula</i> sp. nov. (Figs. 1–4) <b>Adult habitus.</b> General color black. Head mostly black with yellowish areas forward of anterior ocellus and outside of posterior ocelli. Antennal scape and pedicel black, flagellum dark brown. Palpi brownish. Pronotum black with rugosities on disk, and median suture comparatively obvious (Fig. 1a). Wing membrane brown and veins black. Legs dark brown, coxae brownish. <b>Male</b> (Figs. 1b, 4 a–4d). Forewing length 18.1–20.0 mm. Hemitergal lobes slender, finger-like; apex and ventroapical region with a few spines. Tergum 9 with a black posteromedian patch covered light colored sensilla basiconica; the anterior half of tergum 9 also with sensilla but much less in number. Terga 7–8 without sensilla basiconica (Fig. 1b). Setal brushes present on sterna 4–7. Aedeagus. (Figs. 1 c–1e) mostly membranous except for a pair of small ossified basolateral dark scales; mainly straight but narrow medially in lateral aspect, at apex ventral and dorsal aspect each with an ear like protuberance. Dorsal and ventral aspects resemble triangular bud. Dorsal surface with spinules medially, the spinous area separated by bald band along median one fourth. Ventral surface apical half with fine spinules, the rest without spinules. <b>Female</b> (Figs. 2 a–2e). Forewing length ca. 24.1 mm. Generally similar to males, body color slightly lighter. Fully grown adult with 7 mature eggs dissected from the 8 th abdominal segment. Subgenital plate with a short fan shaped apex which extends backwards overlapping the anterior third of sternum 9. Posteromedial notch of the apex wide and deep, roughly resembling a tent. Vagina membranous, outline basally rectangular with an anteromedian notch and a pair of mediolateral incisions. Spemathecal stalk evenly curved, slender and a little longer than vagina length. Spermatheca broken. Egg (Figs. 2f, 3 a–3f). Several mature eggs were dissected from female abdominal terminalia. Outline oval with short stalked collar and opercular end pointed and nipple like. Cross section round (Fig. 3e). Chorion dark brown, 413–461 µm long and 304–306 µm wide (N=5). Micropyles 3–7 with rim slightly raised. Collar rim flanged surrounded by an elongate irregular row of follicle cell impressions (FCIs). Collar length 35–43 µm, diameter across rim ca. 98–104 µm (Figs. 3 b–3c). Chorionic surface mostly smooth except for a row of FCIs of irregular shape at collar end (Figs. 3 b–3c). <b>Type material.</b> Holotype male, China: Shaanxi Province, Ningqiang County, Qingmuchuan Town, Qingmuchuan National Nature Reserve, Qingmuchuan Protection Station, black light trap, 32.83 N, 105.56 E, 669 m, 2018. IV.23, Chunyan Jiang, Zhe Li (HIST). Paratypes: 4 males and 1 female, same data as holotype; 2 males, same date and Reserve, Fenlinba, 32.88 N, 105.54 E, 833 m, light traps, Chunyan Jiang, Zhe Li. <b>Etymology</b>. The specific epithet refers to yellowish spots near the ocelli on the head and is derived from Latin composition of “flavidus” and “macula”, meaning yellowish and mark, respectively. <b>Distribution</b>. China (Shaanxi Province). <b>Remarks</b>. The dark body color of <i>K. flavimacula</i> is most similar to <i>K. bimaculata</i> Du &amp; Sivec 2005 from Gansu Province near to the type locality of the new species. However, the legs of the new species are dark brown, and the wing membrane is brown. The legs are yellow and wing membrane is hyaline in <i>K. bimaculata</i> according to the original description. <i>Kamimuria flavimacula</i> also differs from <i>K. bimaculata</i> by lacking sensilla basiconica on tergum 8 and in the male, lacking dark scale patches on the dorsum of aedeagus. Two other dark species, <i>K. guangxia</i> Li &amp; Wang 2013 (in Wang <i>et al.</i> 2013) and <i>K. atra</i> Sivec &amp; Stark 2008 have dorsal head patterns that are apparently different and the hemiterga lobes are less curved with different arrangements of the fine spinules.
