Limois sordida sp. nov. urn:lsid:zoobank.org:act: 4B5CE928-5341-4712-9B98-3F5DF7AA7F37 Figs 6–7, 15 A–D Diagnosis (1) Frons with 3 longitudinal carinae (Fig. 6E); (2) tegmina with along irregular stripe, sinuately extending to anal angle (Fig. 6 A–C); (3) gonostyli almost equilateral in lateral view; (4) hindwings pale yellow in basal ⅖, medially without fascia (Fig. 6 A–B). Etymology The specific epithet alludes to the sordid color of the clypeus. Type material Holotype CHINA • Ƌ; Shanxi, Ningwu, Mt. Luyashan; 25 Oct. 2011; Ai-ping Dong leg.; NWAFU.

Including eyes distinctly narrower than pronotum (about 1: 1.7) (Fig. 6D). Vertex quadrangular, about 2 times as broad as an eye, lateral and posterior margins carinate, median carina obscure; cephalic process flattened, not reaching posterior margin of vertex (Fig. 6D, F). Frons medially with 3 longitudinal carinae, the median carina tinier, all not reaching fronto-clypeal suture; clypeus sordid, narrower and shorter than frons, labium elongate, reaching the end of abdomen, median carina on clypeus (Fig. 6E). THORAX. Thorax macular covered with numerous dark spots, pronotum about 1.6 times as long as vertex in dorsal view, with one longitudinal broken band on each side of median carina, black (Fig. 6D); mesonotum with 3 pairs of dark patches along anterior margin and one dark triangular patch on each lateral area (Fig. 6D). TEGMINA. Brownish yellow on basal ⅖ and costal area, with narrow irregular stripe from costal area, extending to anal angle; remaining area of tegmina hyaline with some dark markings, veins ochre brown, about 2.7 times as long as maximum broad (Fig. 6 A–C). HINDWINGS. Pale yellow on basal ⅖, with 4–5 black spots arranged in one oblique row, apical ⅗ of hindwings hyaline with a brown band along suture margin (Fig. 6 A–B). LEG. Brown with black rings and stripes. Metatibiae with 5–8 lateral and 6–7 apical spines. ABDOMEN. Tergites black, posterior margin ochre yellow on each segment (Fig. 6A). MALE GENITALIA. Pygofer in profile with ventral margin straight, laterocaudal margin slightly convex (Figs 7A, 15A). Anal tube moderate, in lateral aspect reaching level of end of genital plates, ventral margin slightly concave in basal ¾, apical margin truncate, intersecting with dorsal margin at obtuse angle, epiproct right-angled apically, paraproct slender in dorsal view (Figs 7 A–B, 15A). Gonostyli subtriangular in lateral view, rounded apically, apical margin straight in middle, in ventral view plates connected in basal ⅕ (Figs 7A, C, 15 A–B). Aedeagus reduced, membranous endosoma with a dorsal pair of lobes surrounding a ventral pair of lobes and the sclerotized endosomal processes; the endosomal processes sclerotized over entire length, about 4.0 times as long as sheath, apical ½ exposed and terminally inflated (Fig. 7 C–E, 15C–D). Connective rod-like. Tectiductus large, in lateral view subrectangular, in dorsal view broad, apically rounded and distinctly concave medially (Figs 7 C–E, 15A). Distribution China (Shanxi; Hebei, Beijing). Remarks Limois sordida sp. nov. is similar to L. bifasciatus, L. emelianovi and L. kikuchii, but differs from L. bifasciatus by the frons having three longitudinal carinae (Fig. 6E) (with two longitudinal carina in L. bifasciatus); from L. emelianovi and L. kikuchii it differs by the irregular stripe on tegmina long, sinuately extending to anal angle (Fig. 6 A–C) (irregular stripe short and straight, not extending to anal angle in L. emelianovi and L. kikuchii). Furthermore, it differs from L. kikuchii by the gonostyli being almost equilateral in lateral view (Figs 7A, 15 A–B) (elongate in L. kikuchii); from L. emelianovi it differs from the basal ⅖ of hindwings pale yellow in both sexes, medially without fascia (Fig. 6 A–B) (base of hindwings yellow in male but red in female and medially with a blackish brown fascia in L. emelianovi).
