Harpalus kaznakovi lilliputa ssp. n.

( Figs 28–29 , 42–44 )

Type material. Holotype: 1 ɗ, China, Tibet, Zogang Co., 3800 m, 3.VII.1976, Zhang Xuezhong leg. ( IZB). Paratypes: 1 ɗ, same data as holotype, 2.VII.1976 ( IZB); 2 ɗ, Lhünzhub Co., 4200 m, 13.VI.1960, Wang Chunguang leg. ( IZB, ZISP).

Description. Size very small: body length 5.2–5.8 mm. Habitus: Fig. 28 . Head relatively large (in male WHmax/WPmax = 0.69–0.71 and WHmin/WPmax = 0.58–0.60), with convex eyes (WHmax/WHmin = 1.19–1.20). Pronotum relatively narrow, 1.42–1.50 as wide as long, with sides converging posteriad in basal half and basal angles rounded at apices; basal foveae small and narrow; base of pronotum usually almost impunctate, at most with few very fine punctures around basal foveae and along lateral furrows basally. Elytra relatively long, 1.32–1.42 times as long as wide, 2.40–2.62 times as long and 1.17–1.34 times as wide as pronotum; humeral denticle small; preapical sinuation moderate, parascutellar pore present; each third interval with one discal pore. Metepisterna ( Fig. 29 ) approximately as long as wide and more strongly than in H. kaznakovi kaznakovi narrowed posteriad. Metacoxae without additional setae. Median lobe of aedeagus ( Figs 42–43 ) notably bent just after basal bulb; terminal lamella ( Fig. 44 ) comparatively short, with sides usually slightly converging apicad.

Distribution. This new subspecies occurs in eastern and central Tibet.

Etymology. The subspecies epithet refers to the small body of this new taxon.

Remarks. The new subspecies distinctly differs from the nominotypical one in the narrower metepisterna, the smaller body and the terminal lamella of aedeagus more clearly converging apicad.
