Tychius hedysaricus Karasyov, 1991: 143 .

Material examined. CHINA: Shaanxi: Yulin Dingbian, Hedysarum fruticosum var. mongolicum, 22-VII-1987 (2).

Redescription. Length 2.60–3.20 mm (Fig. 113–116). Dorsal integument completely hidden by very dense, overlapped, broad, rounded to oval, yellowish to white scales. Elytral interstriae with broadly oval scales in double to triple rows, and narrower and sparse scales in a median row. Rostrum (Fig. 235–238) in lateral view tapered and slightly curved in male, slightly tapered and curved in female (Rl/Rw 5.83–5.87 in male, 7.20–7.27 in female; Rl/Pl 0.85–0.93 in male, 0.90–1.03 in female). Eyes flat. Pronotum (Pw/Pl 1.07–1.11) with slightly curved sides in basal half. Elytra (Ew/Pw 1.25–1.33; El/Ew 1.73–1.90), rectangular, elongate. Femora (Fig. 303–304) unarmed. Tibiae (Fig. 338) without sexual characters. Third tarsomere distinctly wider than second tarsomere (Fig. 350). Claws (Fig. 362) with small medial teeth, as long as half of claw, fastened to claw in basal half. Male genitalia: body of penis (Fig. 395) moderately wide and with sides slightly convergent in basal 2/3, then distinctly narrowed and parallel sided to apex, with narrow and blunted tip (Fig. 430), with apex in lateral view upturned, 1/3 longer than apodeme. Female genitalia: spermatheca (Fig. 456) with long parallel-sided ramus slightly curved inwards, short robust collum, robust nodulus, cornu gradually narrowing to apex; spiculum ventrale (Fig. 483) with arms almost joined for their whole length.

Remarks and comparative notes. As reported by Karasjov (1991) this species, described based on specimens from Mongolia which we examined, differs from T. gracilitubus by the moderately straight rostrum (especially in the female) and the shape of the penis. The spermathecae are also distinctly different.

Biology. This species occurs in both Mongolia (Karasjov, 1991) and in China on Hedysarum fruticosum Pall. var. mongolicum (Turcz) B. Fedtsch.

Distribution. This species was previously known only from Mongolia. New record from China (SHA).
