Diagnosis.
Body mostly black (Fig. 3A View Figure 3 ), antenna with scape yellowish brown, funicle yellowish brown to brown and club yellowish brown; fore and mid legs yellowish brown, metafemur reddish brown; eye (Fig. 3D View Figure 3 ) with dense and long setae; scape shorter than pedicel to Fu2 combined; Fu1 longest; all the funicular segments longer than broad; postmarginal vein shorter than marginal vein and 3.5 × as long as stigmal vein (Fig. 3E View Figure 3 ); Gt1 with two longitudinal carinae at base, between them with some longitudinal striae (Fig. 3H View Figure 3 ).
Description.
Male (holotype). Body length 2.9 mm, mostly black (Fig. 3A View Figure 3 ). Head and mesosoma with dense punctures and white pubescence; antenna (Fig. 3C View Figure 3 ) with scape yellowish brown, funicle yellowish brown to brown and club yellowish brown; eye silvery gray and ocelli brownish (Fig. 3D View Figure 3 ); tegula yellowish brown; fore and mid legs yellowish brown; hind leg mostly reddish brown except yellowish brown tarsus, distal apex of tibia yellowish brown; fore wing hyaline, venation brownish.
Head (Fig. 3B, D View Figure 3 ) with long, white pubescence, 1.2 × as wide as long in frontal view; eye with long, white setae; scrobe not reaching anterior ocellus, finely striate; preorbital carinae distinct and not reaching behind anterior ocellus; POL 5 × as long as OOL; antenna (Fig. 3C View Figure 3 ) with scape shorter than pedicel to Fu2 combined; pedicel small; Fu1 longest, 1.7 × as long as broad; all the funicular segments longer than broad; Fu2-7 subequal in length; club 2-segmented, 2.6 × as long as maximum width, 1.8 × as long as and about as broad as the preceding segment.
Mesosoma (Fig. 3I View Figure 3 ) with dense punctures and white pubescence, apex of mesoscutellum with two teeth, pubescence on mesoscutellum longer than that on pronotum and mesoscutum; propodeum (Fig. 3F View Figure 3 ) with submedian carinae distinct and parallel, between them with some transverse and fine striations. Fore wing hyaline (Fig. 3E View Figure 3 ), 2.4 × as long as broad; postmarginal vein shorter than marginal vein and 3.5 × as long as stigmal vein. Metafemur (Fig. 3G View Figure 3 ) and metatibia with long and white pubescence; metacoxa with coxal tooth on baso-dorsal side; metafemur 2.2 × as long as broad, with a row of comb of teeth but without forming any lobes.
Metasoma (Fig. 3H View Figure 3 ) oblong, 1.6 × as long as broad in dorsal view; Gt1 longest, occupying 0.6 × length of metasoma with two longitudinal carinae at base, between them with some longitudinal striae, with white pubescence on lateral sides; dorsal surface of Gt2-6 with microsculptured and white pubescence.

Distribution.
China (Heilongjiang).
Variation.
Two paratypes differ from the holotype by having black eyes, but no other significant differences were found in the available material.
Etymology.
Latin: stria = furrow, line; and refers to the longitudinal striae between two longitudinal carinae of T1.
Comments.
Haltichella strigata sp. nov. is similar to H. achterbergi Narendran, 1989 in having a similar shape of the antenna and the metasoma, but can be separated from the latter by the following combination of characters. The new species has the fore wing hyaline (vs partly infuscated in H. achterbergi ); Gt1 with some striae between the two longitudinal carinae (vs absent); postmarginal vein shorter than the marginal vein (vs longer); dorsal surface of Gt 2-6 with white pubescence (vs glabrous and polished on the dorsal side medially).
Compared with other species of this genus, the new species differs by having dense and long setae on its eyes (Fig. 3D View Figure 3 ) and Gt1 with some striae between the two longitudinal carinae. 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.
