Harpalus giacomazzoi gracilis ssp. n.

( Figs 51–53 )

Type material. Holotype: ɗ, China, Tibet, Markam Co., 3700 m, 11.IX.1981, Wang Shuyong leg. ( IZB).

Paratypes: 3 ɗ, 2 Ψ, same data as holotype, Wang Shuyong (4 specimens) and Liao Subai (1 specimen) leg. ( IZB, ZISP).

Description. Medium sized: body length 7.5–8.8 mm. Head relatively large (WHmax/WPmax = 0.64– 0.67 and WHmin/WPmax = 0.52–0.56). Pronotum comparatively small, rounded at sides, almost evenly narrowed apicad and basad, with base slightly wider than apex; basal angles widely rounded. Elytra relatively long, 1.36–1.40 times as long as wide, 2.45–2.52 times as long and 1.11–1.20 times as wide as pronotum; preapical sinuation weak. Wings reduced to scale extending to about 1/3 of elytra. Three last abdominal sternites glabrous. Metacoxae usually without additional setae, occasionally with one medial seta on right or left metacoxa. Metafemur with 4–6 setigerous pores along posterior margin ventrally. Median lobe of aedeagus with terminal lamella slightly widened apically ( Fig. 53 ); internal sac with rather narrow longitudinal spiny patch and two extremely small individual teeth ( Figs 51–52 ).

Distribution. This new subspecies is known from Markam County, eastern Tibet, China.

Etymology. The subspecific epithet refers to the slender body of the new subspecies.

Remarks. This new subspecies differs from the nominotypical subspecies in the body more slender, the head relatively larger, the pronotum more strongly narrowed basad, and the terminal lamella of the median lobe of the aedeagus less notably widened apically.
