Type material
Holotype, ♂ (NEFU), China, Xizang Province, Bomi County, Shuangyu Village, 8.VIII.2017, sweeping, Hui-Lin Han. Paratypes (NEFU): 2 ♂, same data as holotype.
Diagnosis
Body black (Fig. 2A), antenna with scape yellowish brown and flagellum yellowish brown to brown; fore and mid legs yellowish brown; scrobe not reaching anterior ocellus (Fig. 2B); antenna (Fig. 2C) slender, scape longer than pedicel to Fu2 combined; all the funicular segments longer than broad; mesoscutellum apically with two diverging teeth (Fig. 2I); submedian carinae of propodeum indicated, distinct on posterior half (Fig. 2F); fore wing (Fig. 2E) largely hyaline with small brown patch adjoining marginal vein; postmarginal vein slightly longer than stigmal vein; metasoma (Fig. 2H) fusiform, Gt1 occupying 0.6× length of metasoma, Gt2 with the basal half smooth and distal half with microsculptured and white pubescence.
Description
Male (holotype). Body length 2.9 mm, mostly black (Fig. 2A), head and mesosoma with dense punctures and white pubescence; antenna with scape yellowish brown and flagellum yellowish brown to brown; eye and ocelli silvery gray (Fig. 2D); tegula yellowish brown; fore and mid legs yellowish brown; metacoxa black, metatrochanter yellowish brown, metafemur black with base yellowish brown to reddish brown, metatibia black with apex yellowish brown, metatarsus yellowish brown; fore wing largely hyaline with small brown patch adjoining marginal vein and venation brownish.
Head (Fig. 2B, D) with coarsely rugose punctures, 1.2× as wide as long in frontal view; scrobe slightly wider, not reaching anterior ocellus, finely striate; preorbital carinae distinct; POL 5× as long as OOL; antenna (Fig. 2C) slender; scape longer than pedicel to Fu2 combined; pedicel small; anellus short and transverse; Fu1 longest, 1.7× as long as broad; Fu2–7 approximately equal in length, all the funicular segments longer than broad; club 2-segmented and slender, 3.2× as long as maximum width, 2× as long as and as broad as the preceding segment.
Mesosoma (Fig. 2I) with dense punctures and white pubescence; apex of mesoscutellum with two diverging teeth, inner margins of the two teeth at a right angle; submedian carinae of propodeum (Fig. 2F) indicated, distinct on posterior half. Fore wing hyaline (Fig. 2E), forewing 2.6× as long as broad; submarginal vein 4× as long as marginal vein, marginal vein 1.6× as long as postmarginal vein, postmarginal vein slightly longer than stigmal vein. Metafemur and metatibia with long and white pubescence (Fig. 2G); metacoxa with coxal tooth on baso-dorsal side; metafemur 2.3× as long as broad, with a row of comb of teeth.
Metasoma (Fig. 2H) fusiform, 2× as long as broad in dorsal view; Gt1 dorsum smooth and shiny, occupying 0.6× length of metasoma, with two longitudinal carinae at base; Gt2 with basal half smooth and distal half with microsculptured and white pubescence; dorsal surface of Gt2–6 with sparse microsculptured and white pubescence.
Female. Unknown.
Hosts
Unknown.
Distribution
China (Xizang).
Etymology
The specific name is derived from the name of the collection locality of the holotype.
Comments
The new species is similar to H. variicolor Masi, 1929 in having similar colouration and shape of the antenna and similar shape of the scrobe, but can be separated from the latter by the following characters. The new species has the marginal vein 1.6× as long as the postmarginal vein (vs postmarginal vein longer than marginal vein in H. variicolor) and metafemur without prominent first tooth (vs first tooth present and prominent).
The new species is characterized by two diverging teeth of the mesoscutellum, a unique propodeum and the scrobe not reaching the anterior ocellus. A female holotype would be preferable but we failed to collect female specimens. However, most likely the female will share at least part of the differences listed for the male holotype.
