Serralanguria sinensis Huang sp. nov.Figs 1 A – C, 2 A – FType material.Holotype: 1 &male;. China Guangxi Longsheng, Huaping Cujiang, 8 Aug. 2006, Meiying Lin leg. // Holotype [red label]; Paratypes: • 1 &female;. Same data as holotype; 1 &female;. Hainan Island Qiongzhong, 800 m, CAS // 1980. Apr. 5 // Paratype [yellow label].Other material.1 &male;, 1 &female;, Guangdong Meizhou Pingyuan County, 15 Apr. 15 2024, alt. 1000 m, Zubin Chen, Liang Guo leg. (Private collection of Zubin Chen, Fujian, China, examined through pictures from the collectors) (Fig. 3 A, B).Diagnosis.This species is readily distinguished from Serralanguria ochreipennis (Fowler, 1890), comb. nov. by its coloration: the pronotum is orange-brown with a continuous black median stripe extending from the anterior to posterior margin, whereas in S. ochreipennis comb. nov. the pronotum is subunicolorously black.Description.Body length 5.0–7.0 mm. Antennae and legs entirely dark brown or black. Body orange-brown, with one dark brown longitudinal stripe from middle of head, extending posteriorly along dorsal surface, but not reaching elytral apex, sometimes interrupted at pronotal base. Clypeus black. Ventral surface black with one longitudinal yellow stripe running from prosternum to abdominal apex. Dorsal surface glabrous; ventral surface bearing scattered short, decumbent setae.Head comparatively large; vertex nearly smooth, sparsely and weakly punctate, without setae, and short setae along anterior margin and around compound eyes; clypeus broadly protruding; gena prominently projecting anteriorly; gular suture deep and widely separated. Eyes prominent, finely faceted. Antennae elongate, exceeding elytral humeri; club six-segmented, segments mostly wider than long; terminal antennomere elongate-oval, covered with moderately dense setae.Thorax. Pronotum spherical and convex, slightly broader than long, nearly smooth and with fine, sparse punctation; lateral pronotal carinae visible dorsally; anterior angles rounded, posterior angles acute but not reaching elytral humeri. Basal foveae short, deep; basal margin complete, distinct. Prosternum finely punctate with yellow setae; prosternal process elongate, apex straight. Prohypomera bearing yellow setae near anterior angles. Scutellar shield narrowed at base and rounded at apex. Elytral surface with shallow, striate punctures arranged in regular rows; shoulders distinct, broader than pronotal base; apex tapering, rounded, not forming sutural angle. Mesoventrite finely punctate; metaventral median suture incomplete anteriorly, not reaching anterior margin of metaventrite. Abdomen finely punctate; ventrite 1 without postcoxal lines; last ventrite with dense yellow setae apically.Legs slender; terminal tarsomere thickened apically in both sexes.Genitalia. Aedeagus slender, elongate; median lobe gently curved in ventral view, apex abruptly deflexed; paramera slender, apically fringed with long yellow setae. Ovipositor short; coxites narrowly sclerotized, acute apically, bearing distinct styli with long setae.Sexual dimorphism.Pronotum in males more strongly convex and broadly rounded compared to females; terminal antennomere proportionally more elongate in females than in males.Etymology.The specific epithet, sinensis, is a Latinized adjective “ Chinese. ”Gender.Feminine.Distribution.China (Guangdong, Guangxi, Hainan).Comments.Although the individuals shown in Figs 3 A, B, 4 B could not be examined directly, their morphological features, such as body shape, the distinctly elongate and oval terminal antennomere, and the characteristic coloration pattern, are fully consistent with those of the holotype and paratypes of Serralanguria sinensis. While some variation in overall coloration and the intensity of dark markings is observed among these individuals, no other known species of Languriinae exhibits the same combination of characters. Notable color variation between freshly collected and dried specimens is observable comparing the images in Figs 3, 4 and the specimens from the type series. A live individual was photographed in the field by Mr. Qian-Le Lu (Visiting Lecturer, Shenzhen University, China) on 20 June 2025 at Huaping Village, Guangxi, China, within the Huaping National Nature Reserve (Fig. 4 A). The individual (Fig. 4 B) displays a vivid orange-red coloration, whereas all type specimens preserved in the collection exhibit a duller orange-brown tone. The last-mentioned specimen was not collected but only documented by a photograph in the field. Therefore, the authors suppose that these three specimens with comparable body size to the type specimens can be interpreted as conspecific with the holotype of Serralanguria sinensis Huang, gen. et sp. nov.
