Harpalus viridanus staudingerianus Schauberger, 1932: 42 . Type locality: Min-Tschou (= Minxian), Gansu, China

Type material. Syntypes: 14 ɗ, 17 Ψ labelled "Minchow, China ", "Cotype", " viridanus Mots. , s. staudingerianus Schaub.", "W. H. Muche, Radeberg, Ankauf", "Staatl. Museum für Tierkunde, Dresden" ( MTD).

Additional material examined. China. GANSU: 1 ɗ, 2 Ψ, Minxian Co., 20.VII.1987, Zhong Tiesen leg. ( IZB); 1 ɗ, "Kan–ssu ["Pag. Sche-pu et fl. Po-i-cho, 1937 m ", NE of Nanping near border with Sichuan], 1885, G. Patanin/ 13.VII " ( ZISP); 1 ɗ, "Kan-ssu [= Jonê, ca 50 km NW of Minxian], 1885, G. Patanin/ 10.VI " ( ZISP); 1 ɗ, "Kan-ssu, 1885, G. Patain/ 18.VI " [= Dangchang, ca 80 km SE of Minxian] ( ZISP).

Description. Very large: body length 8.7–11.0 (usually above 10.0) mm, with or without metallic lustre on dorsum. Head relatively small (WHmax/WPmax = 0.60–0.63 in male and 0.60–0.65 in female; WHmin/ WPmax = 0.53–0.55 in male and 0.53–0.57 in female). Pronotum ( Fig. 9 ) with comparatively wide base (WPmax/WPmin = 1.03–1.08) and with sides more or less parallel basally, sometimes slightly converging posteriad. Pronotal basal angle right-angled or slightly obtuse, usually with somewhat sharp or slightly blunt apex. Elytral striae deepened and intervals convex, particularly markedly near apex. Dorsal microsculpture visible throughout on head, pronotum and elytra, consisting of distinct, more or less isodiametric meshes. Median lobe of aedeagus ( Figs 11–12 ) medium–sized (LB/LML = 3.30–3.54); terminal lamella ( Fig. 14 ) comparatively long, with sides more or less notably sinuate, sometimes nearly parallel before apex.

Distribution. This subspecies seems to have a small range in southernmost Gansu.

Remarks. Described from more than 50 specimens captured in Minxian, Gansu, China. In habitus, it is similar to the nominotypical subspecies but distinguished by larger body. This form seems to be distinct although probably is connected with the nominotypical subspecies by the narrow transition zone to the north of Minxian.
