Diagnosis. Recognizable by having clypeus with one seta on each side anteriorly, labial basal palpomere with oblique carina underneath, pronotum with one lateral seta on each side and with basal angles somewhat blunt at apex, pronotal disc in central portion punctate, elytra densely punctate and pubescent on all intervals, without row of discal pores on intervals 1, 3, 5 and 7, and legs pale, reddish brown or brownish yellow. Internal sac of median lobe of aedeagus is usually without any sclerotized elements (Figs 20–21), occasionally with a very small and short spine apically (Fig. 19). Body length 12.2–16.9 mm.
Distribution. China: mostly in the north-eastern part. It was recorded from Heilongjiang, Jilin, Liaoning, Qinghai, Shandong, Jiangsu, Shanghai, Shanxi, Shaanxi, Gansu, and Sichuan (Kataev et al. 2003). We also examined specimens from Hebei, Hubei and Hunan. According to Hua (2002), this species also occurs in Henan and Xizang; as Harpalus vicarius, he also reported it from Nei Mongol, Henan, Anhui, and Xizang (see remarks below). Harpalus ussuriensis is recorded here from Hunan for the first time.
The species is also known from Eastern Russia (Buryatia, Chita and Amur Provinces, Khabarovsk and Maritime Provinces, southern Sakhalin, southern Kurils), North and South Korea including Jejudo, and Japan (Hokkaido, Honshu, Sikoku, and Kyushu Islands) (Habu 1973; Lafer 1989; Kryzhanovskij et al. 1995; Kataev 1997; Kataev et al. 2003; Moon & Paik 2006).
Remarks. In southern Sakhalin, southern Kurils and Japan, the species forms the subspecies H. u. vicarius Harold characterized by, on average, wider head, narrower pronotum, longer and wider elytra, and shorter metepisterna (Kataev 1997). All records of this taxon from mainland China, for example from Jilin (Park et al. 2001) and from Heilongjiang, Nei Mongol, Hebei, Shaanxi, Henan, Hubei, Anhui, Sichuan and Xizang (Hua 2002), should be referred to the nominotypical subspecies.
