description: Halosalda minuta Vinokurov, Luo & Lü, sp.n.
(Figs. 2–12, 18, Table 1)
Differential diagnosis. Recognized by the small body size (2.7–3.1 mm), narrow frons (Fig. 3), narrow flattened lateral margin of pronotum, relatively long 2nd antennal segment (in male 1.47–1.52 x, in female 1.32–1.35 x as long as head width), and genital structures (Figs. 7–11). Eastern Mediterranean H. coracina Cobben, 1985 is similar to the new species in dark body color and wing brachyptery, but can be distinguished from the latter by the larger body (see Table 3), wide frons (Fig. 13), and male genitalia structure (Figs. 14, 15).
Description. Small sized, semi-brachypterous, with oval, shining black body and large head. For measurements see Table 1.
Male. 2–2.2 × as long as width (Fig. 2).
Head. Large (0.84–0.85 x as wide as width of pronotum at base), eyes large, frons narrow, with fine scabrous sculpture, with very short erect setae visible at large magnification, mid frontal pale spots oblong and yellow (Fig. 3). Vertex shining, distance between ocelli larger than diameter of one ocellus, preocellar spots round and white. Anteclypeus, mandibular, and maxillary plates, lateral swelling between eye and antennal socket yellowish-white to yellow. Labrum yellow or brownish-yellow. Labium long, almost reaching hind coxae, segment 2 (first visible) bright yellow, segment 3 dark brown and segment 4 yellow-brown. Antennae thin. Segment 1 thickened, with rare erect black spines, yellow to brown-yellow, ventrally with broad black stripe. Segment 2 slightly thickened near apex, yellow, with short black semierect setae. Segments 3 and 4 yellow-brown, with black, short, adpressed, and long erect setae.
Thorax. Pronotum black and shining, callus noticeably convex, with shallow transverse pit, separated from collar and posterior lobe by deep furrow. Lateral margins of pronotum flattened, slightly convex in middle, yellow, outer part with fine black edging. Scutellum shining, with setae similar to those on wing. Thoracic venter glossy, acetabulae 1 and 2 white.
Legs. Yellow-white, with short black setae. Coxae dark-brown. Fore femora ventrally with long brown stripe, middle and hind femora with short brown stripes near apex dorsally and on hind margins. Black spines on fore and middle tibiae thin and scarce, on hind tibia thick and long. Tarsal segment 3 apically darkened, claws yellow.
Wing. Clavus and corium shining, rugose, with rather dense short semierect black setae. Apex of clavus broadly yellow in pale specimens, with small unclear yellow spot in dark specimens. Endocorium black, exocorium yellow-white, with large black spot on distal half. Membrane noticeably reduced and coriaceus, cells whitish to yellow-brown, veins distinctive and dark brown.
Abdomen black and shining, with short, rather dense black setae.
Genitalia. Paramere stout, with wide body, processus hamatus thick and straight; processus sensualis prominent, low, with a few short thin setae; outer side with very long dark-brown rough setae (Fig. 7, 8). Parandria narrow and parallel (Fig. 9). Penisfilum of aedeagus forming 1.5 coils (Fig. 10). Median endosomal sclerite as in Fig. 11.
Female. 2–2.2 x as long as wide. Vestiture as in male.
Head 0.78–0.84 x as wide as width of pronotum at base. Anteclypeus, mandibular and maxillary plates yellowbrown; lateral swelling between eye and antennal socket black; labrum yellow-brown, with base and apex darkened; preocellar spot and mid spots on frons darkened. Antennal segment 1 black, segment 2 dirty yellow, segments 3 and 4 yellow-brown or dark brown. Labium surpassing middle or reaching hind coxae. Segment 2 yellow, segment 3 brown-black, segment 4 yellow-brown or brown-black.
Thorax. Flattened lateral margins of pronotum slightly convex and black, yellow near anterior corner. Prothorax black, in pale specimens with small yellow spot under posterior angles of pronotum. Acetabulae 1 and 2 yellow-brown or black with narrow yellow brown edge.
Wing. Hemelytra black or blackish-brown. In pale specimens apical part of clavus with narrow yellow spot, exocorium white, with midst large black spot (Fig. 4). In dark specimens exocorium black, with narrow brown stripe in outer part, apical small yellow spot with fuzzy edges (Figs. 5, 6). Membrane yellow-brown to dark-brown, in dark specimens with unclearly visible veins and small dark-brown spots.

Comparative notes. The type series of Halosalda minuta sp. n. was collected from the eastern part of the Tarim Depression. Specimens were collected in May in the desert about 80 km east of the closed salt lake Lop Nur (Lob-Nor).
The new species is close to H. coracina Cobben in the degree of wing brachyptery and domination of dark color on pronotum and hemelytra. A comparison of the new species, H. coracina, and H. lateralis Fall. (the latter is given according to Cobben 1985), is summarized in Table 2.
Distribution. Lop Nur Natural Reserve, Eastern Xinjiang, China.
Biology. Bugs were collected near shallow ephemeral pools with grasses (Fig. 18).
Etymology. The species is named because of its small size, which is not typical for the genus Halosalda Reut.
