Type material.
Holotype: China: 1♂, Xizang, Jilong County, Jilong Town, Jipu Village, 28°37'N, 85°32'E, 2744 m, 9 Aug. 2019, Dan Zhang, Qing-Tao Wu leg. Paratypes: 5♀21♂, Jilong County, Jilong Town, Jipu Village, 28°37'N, 85°32'E, 2744m, 7-9 Aug. 2019, Dan Zhang, Qing-Tao Wu leg.; 16♀1♂, Xizang, Jilong County, Jilong Town, Xinjiang Village, 28°22'N, 85°21'E, 2727m, 6 Aug. 2019, Dan Zhang, Qing-Tao Wu leg.
Diagnosis.
Males of L. guihongi sp. nov. differ from other species of subgenus Lipotriches Lipotriches by the following combination of features: mesoscutum, metapostnotum and center disc of metasomal terga with dense and large punctures (Fig. 1c, d View Figure 1 ), S4 with dense short white hairs (Fig. 1f View Figure 1 ); S5 with a pair of circular protruding thickness on the disc, a pair of triangular feathery bristles connected on the apical margin (Fig. 1g View Figure 1 ); L. guihongi is most similar to Lipotriches yasumatsui Hirashima, 1961 and Lipotriches ceratina (Smith,1857), however, the male of the new species can be distinguished from the two latter by a pair of large, dense, erect and brownish longitudinal tufted hairs on S5. In addition, S5 structure of L. guihongi sp. nov. is similar to L. acanthospermi Pauly, 2014b. We have found that the both species have dense tomentum on S4 and a pair triangular feathery bristles on the apical margin of S5, while the latter lacks a pair of circular protruding thickness on the disc of S5, and has only been found in Africa.
Description.
Male (measurements are only from the holotype). BL = 8 mm (Fig. 1a View Figure 1 ), body black. Head. HL: HW = 0.89, head broader than long (Fig. 1b View Figure 1 ); clypeus broader than long (Fig. 1b View Figure 1 ); paraocular area with dense large punctures (i = 0.1-0.2d; Fig. 1b View Figure 1 ); vertex with sparser large punctures (i = 0.5-1d; Fig. 1b View Figure 1 ); vertex behind shiny; posterior margin of vertex rounded (Fig. 1a, b View Figure 1 ); mandible blackish-brown; frons with dense and minute punctures, medial frontal line smooth (Fig. 1b View Figure 1 ); antenna reaching the posterior margin of T1; F1-11 almost equal in length, nearly 2.3 times as long as broad (Fig. 1a, b View Figure 1 ); ocelli normal (Fig. 1b View Figure 1 ). Mesosoma. Mesoscutum, scutellum, and metanotum dull, without reflections (Fig. 1c View Figure 1 ). Mesoscutum with large and mostly confluent punctures (i = 0.2-0.3d; Fig. 1c View Figure 1 ); metanotum normal, without process, with large punctures which are sparser than punctures on the mesoscutum (Fig. 1c View Figure 1 ); posterior surface of propodeum with more larger and denser (i = 0.1-0.2d) punctures than those on the mesosoma (Fig. 1d View Figure 1 ); metapostnotum shiny, with broad longitudinal wrinkles (Fig. 1d View Figure 1 ); fore wing with three submarginal cells, the 1st and 3rd submarginal cell nearly equal in length, almost two times as long as 2nd submarginal cells; tegula oval, yellow-brown, not enlarged (Fig. 1c View Figure 1 ); femur and tibia black (Fig. 1a View Figure 1 ); basitarsus, mediotarsus yellow-brown with tarsal claw (Fig. 1f View Figure 1 ); hind femur and tibia normal, not enlarged (Fig. 1c View Figure 1 ). Metasoma. Surface of metasomal terga shiny, center of disc with dense punctures (i = 0.2-0.3d), apical of disc with sparser punctures than on the center (i = 0.5-1d); apical margin of T1-5 transparent (Fig. 1e, f View Figure 1 ); S5 with a pair of circular protruding thickness on the disc, a pair triangular feathery bristles on the apical margin connected (Fig. 1g View Figure 1 ); gonostylus as shown in Fig. 1h View Figure 1 (in dorsal view) and Fig. 1i View Figure 1 (in lateral view). Pubescence. Clypeus, supraclypeal area and frons with white setae (Fig. 1a, b View Figure 1 ); scutellum with sparse long yellowish hairs (Fig. 1c View Figure 1 ); metanotum with dense pale tomentum (Fig. 1c View Figure 1 ); upper lateral surface of propodeum with sparse long white hairs (Fig. 1d View Figure 1 ); legs with sparse white hairs (Fig. 1a, d-f View Figure 1 ); apical area of metanotum with sparse long hairs (Fig. 1c View Figure 1 ); apical margin of T1-4 with white hair band, interrupted in middle (Fig. 1e View Figure 1 ); S4 covered with dense pale tomentum (Fig. 1f View Figure 1 ).
Female. BL = 10-12 mm. Similar to male, except the following: metapostnotum with punctures sparser (i = 0.4-0.5d) and smaller than male’s (Fig. 2d View Figure 2 ); head, mesosoma and metasoma with sparse yellowish hairs (Fig. 2b View Figure 2 ); T1-2 with densely and minutely punctures (i = 0.2-0.3d; Fig. 2d View Figure 2 ).
