Diagnosis
Body black (Fig. 1A), scape to Fu3 yellowish brown, Fu4–7 and club dark brown (Fig. 1C), fore wing cinereous with two brown patches (Fig. 1E); scape (Fig. 1C) approximately half as long as remaining antennomeres combined, pedicel 1.5× as long as Fu1, Fu1–7 gradually increases in breadth and Fu4–7 gradually decreases in length distad; mesoscutellum (Fig. 1H) as long as broad, apex with two teeth, distance between outer margins of the two teeth about 1.4× as long as individual length of teeth; propodeum (Fig. 1F) with irregularly rugose in middle area; postmarginal vein (Fig. 1E) absent, marginal vein 3× as long as stigmal vein; metasoma oval; Gt1 occupying 0.7× length of metasoma (Fig. 1H).
Description
Female (holotype). Body length 2.9 mm, mostly black (Fig. 1A), with dense punctures and white pubescence; antenna (Fig. 1C) with scape to Fu3 yellowish brown, Fu4–7 and club dark brown; eye and ocelli silvery gray (Fig. 1D); tegula testaceous; fore and mid legs yellowish brown; metacoxa black with apical reddish brown, metatrochanter yellowish brown, metafemur black with base yellowish brown to reddish brown, apex reddish brown, metatibia black with base slightly reddish brown, apex yellowish brown, metatarsus yellowish brown; fore wing (Fig. 1E) cinereous with two brown patches, one adjoining marginal vein and another near posterior margin of wing, venation brown.
Head (Fig. 1B, D), with coarsely rugose punctures, except in scrobal area, 1.2× as wide as long in frontal view; scrobe reaching anterior ocellus, finely striate; preorbital carinae distinct; POL 4.3× as long as OOL; antenna (Fig. 1C) clavate; scape approximately a half of remaining antennomeres combined; pedicel triangular, longer than broad; anellus quadrate, looks like a funicular segment; Fu1–2 subquadrate, Fu1 shorter than pedicel, 0.9× as broad as long; Fu3–7 broader than long; Fu1–7 gradually increases in breadth and Fu4–7 gradually decreases in length distad, Fu7 1.5× as broad as long; club coniform, 2× as long as maximum width, 3× as long as and about as broad as the preceding segment.
Mesosoma (Fig. 1H), punctures on mesoscutum and mesoscutellum smaller than on head; mesoscutellum as long as broad, apex with two teeth, distance between outer margins of the two teeth about 1.4× as long as individual length of teeth; outer margins of the two teeth approximately parallel, inner margins of the two teeth meet at an acute angle; propodeum (Fig. 1F) irregularly rugose in middle area. Forewing (Fig. 1E) 2.5× as long as broad; submarginal vein 4.5× as long as marginal vein, marginal vein 3× as long as stigmal vein, postmarginal vein absent. Metacoxa with coxal tooth on baso-dorsal side; metafemur (Fig. 1I) 2.2× as long as broad, with a row of comb of teeth but without forming any lobes.
Metasoma (Fig. 1G) oval, 1.6× as long as broad in dorsal view, surface smooth; Gt1 longest, occupying 0.7× length of metasoma, with two short carinae at base; Gt2–6 with sparse microsculptured and white pubescence on lateral sides.
Male. Unknown.
Hosts
Unknown.
Distribution
China (Hennan, Yunnan).
Etymology
Latin: bi = two; macula = stain, blemish; and refers to the two brown patches on the forewing.
Comments
Haltichella bimaculata sp. nov. is similar to H. nipponensis Habu, 1960 in having similar body colouration and shape of the antenna and similar shape of the metafemur, but can be separated from the latter by the following characters. Haltichella bimaculata has the postmarginal vein of the forewing absent (vs present and shorter than the stigmal vein in H. nipponensis); median area of the propodeum irregularly rugose and the submedian carinae not obvious (vs less sculptured and the carinae distinct and parallel); the mesoscutellum as long as broad (vs longer than broad).
