Tautoneura qingxiuensis Wang & Song sp. nov. Figs 37–40, 41–48 Diagnosis. The new species can be distinguished from other Tautoneura species by subapically broadened the aedeagal shaft in ventral view, with one pair of processes at apex; the extremely short preatrium; the apical gonopore; the dorsal pygofer appendage with base expanded; and the Y-shaped connective, with long, slim stem. Description. Body milky-yellow (Figs 37, 40). Vertex milky-yellow, with pair of gray-yellow spots on either side of coronal suture (Figs 37, 39). Crown yellowish, with fore margin strongly produced medially (Figs 37, 39). Eyes gray. Face milky-white, with base of antenna yellow (Fig. 40). Pronotum milky-yellow, with posterior margin whitish gray (Figs 37, 39). Mesonotum with basal triangles brownish yellow, but inside milky yellow (Fig. 39). Forewing transparent (Fig. 38). Male abdominal apodemes narrow and extending to midlength of 4 th sternite (Fig. 48). Male genitalia. Pygofer lobe with a few fine setae scattered on lateral surfac; pygofer microtrichia conspicuous, well developed; dorsal pygofer appendage distally tapered and basally expanded (Figs 45, 46). Subgenital plate with two macrosetae near middle aera of outer margin and some stout setae scattered near apex (Fig. 44). Style with prominent preapical lobe (Fig. 41). Connective Y-shaped, with long stem, two lateral arms strong, and central lobe rather small (Fig. 47). Aedeagal shaft nearly straight, subapically broadened in ventral view, with pair of processes at apex; gonopore near apex on ventral surface; dorsal apodeme slightly broadened in lateral view; preatrium extremely short (Figs 42, 43). Specimens examined. Holotype: ♂; China, Guangxi Prov., Nanning, Qingxiu Mountain; 21 July 2021; Wenming Xu leg.; GZNU -2021-GX-NN-3-001. Paratypes: 2 ♂♂, 3 ♀♀; same data as holotype; GZNU -2021-GX-NN-3-002 to 006. Measurements. Male length 2.1–2.2 mm, female length 2.2–2.3 mm (including wings). Remarks. This species closely resembles Tautoneura maculosa Sohi, Mann & Shenhmar, 1987, but it can be distinguished by the absence of prominent, dark markings on head, pronotum, and mesonotum (present in T. maculosa), the subgenital plate bearing two macrosetae (vs three), and the much stouter aedeagus than in T. maculosa. Etymology. The new species is named after its type locality, Qingxiu Mountain.
