Tachycines (Tachycines) danpingensis View in CoL sp. nov.
( Figs. 1 View FIGURE 1 ~2)
Description. Male. Body medium-sized ( Fig. 2A View FIGURE 2 ). Vertex divided into two conical tubercles. Eyes normal, not reduced; ocelli visible. Legs elongate and slender; fore femur about 1.49-1.67 times longer than the pronotum, ventrally with 7–15 spines, internal genicular lobe with 1 small spine, external genicular lobe with 1 long spine; fore tibiae ventrally with 1 inner spur and 2 outer spurs, apex with 1 pair small spines on dorsal surface and 1 pair long spines on ventral surface, between the paired ventral small spines with 1 smaller spine. Mid femora with an elongate movable spur on the internal and genicular lobe, ventrally unarmed; mid tibiae ventrally with 1 external and 1 internal spur, apex with 1 pair small spines on dorsal surface and 1 pair long spines on ventral surface, between the paired ventral small spines with 1 smaller spine. Hind femora beneath with 4–6 inter spines and without outer spines; hind tibiae above with 61–64 outer and inner spines respectively, arrange in groups. Super internal spur of hind tibiae not exceeding the dorso-apical spine of hind tarsus ( Fig. 1C View FIGURE 1 ). Hind tarsus with bristles beneath. Central terminal pointed of male epiproct. Epiphallus of male genitalia A-shaped, genital median process of male divide into four lobes at apical ( Fig. 1A View FIGURE 1 ).
Female. General appearance is similar to male ( Figs. 2B View FIGURE 2 ). Subgenital plate with hind margin notched deeply, with small triangles on both sides ( Fig. 1D View FIGURE 1 ). Ovipositor longer than half the length of hind femur.
Coloration. Body crineous with distinct dark brown stripes and speckles. Face with 4 light yellowish longitudinal stripes, located below the antennae and compound eyes respectively. Legs with dark annular stripes.
Measurements. (length in mm) Body: ♂ 14.3-15.0, ♀ 18.0-18.5; pronotum ♂ 5.7-6.1, ♀ 6.7-7.0; fore femora ♂ 8.6- 10.5, ♀ 9.5-10.4; hind femora ♂ 16.6-18.1, ♀ 18.1-20.0; ovipositor ♀ 13.0- 13.5mm.
Material examined. Holotype, 1♂, Danping Village, Zheng’an County, Guizhou Province, alt. 998m, 2019.8.16, collected by Xulin Zhou; paratype, 12♂, 13♀, Danping Village , Zheng’an County , Guizhou Province, alt. 998m, 2019.8.6 ~10.26, collected by Zhengzu Zhou, Xulin Zhou, Huiqin Wu, Dahui Zou.
Distribution. China (Guizhou).
Diagnosis. The new species is rather similar to T. (T.) asynamorus Adelung, 1902 and T. (T.) huaxi Huang & Luo, 2019 , and the three species are different from all other species in this subgenus in that the hind tarsus has bristles ventrally, but there are some salient features in males that distinguish it from the previously two known species. The epiproct of T. (T.) huaxi Huang & Luo, 2019 is transverse and hind margin with notched, and epiproct of T. (T.) asynamorus rather short and rounded; however, the epiproct of T. (T.) danpingensis sp. nov. central terminal pointed. The previously two known species have the hind femora beneath with 7–9 inner spines, but T. (T.) danpingensis sp. nov. with 4-6 inner spines on hind femora. The dorsal apex of semisclerotized median process of male genitalia truncated for the new species, but the dorsal apex of semisclerotized median process of male genitalia acute for T. (T.) asynamorus Adelung, 1902 and the upper apex obtuse of semisclerotized median process of male genitalia for T. (T.) huaxi Huang & Luo, 2019 .
Etymology. The specific epithet refers to the locality Danping village, Guizhou.
