subgenus Parmecus Motschulsky, 1864 , stat. rest., stat. nov.

Type Species: Cicindela dromicoides Chaudoir, 1852 (= Parmecus pictus Motschulsky, 1864 ).

Diagnosis. Head glabrous, coarsely wrinkled; vertex densely rugose, flattened between eyes, with V-shaped impression in the center and small hump on each side with three-four deep longitudinal striae ( Figs 15–17 ); genae glabrous, dense and finely furrowed. First four antennomeres metallic; scape except for a single long apical seta glabrous ( Figs 15 , 20–21 ), or with numeral additional short stout white erect setae ( Figs 16–17 , 22–25 ); the 3 rd– 4 th antennomeres with sparse white short stout erect setae; the 5 th– 11 th antennomeres black, finely and regular pubescent. Labrum pale, lusterless with thin brownish anterior margin, entirely covered by isodiametric microsculpture; unidentate ( Figs 22, 24–25 ) or tridentate ( Figs 20–21, 23 ), transverse. Mandibles pale except for brown teeth. Pronotum indistinctly longitudinal (PL/PW = 1.0–1.15), wrinkled on the disc and densely striated transversely on anterior and posterior lobes, with narrow lateral roves of sparse appressed white setae; with bright purple-bronze V-shaped strip along midline and some coloured vertical strips along midline; proepistermun entirely glabrous or with a few sparse white setae in basal portion, slightly prominent so pronotopleural sutures visible in dorsal view ( Figs 28–33 ); mesepisternum glabrous except few short white setae on posterior-basal margin, entirely finely rugose in males; metepisternum evenly haired by sparse soft white setae. Legs except dark brown trochanters metallic coloured, fore and middle trochanters with a single subapical seta. Elytra oblong, metallic coloured, with numerous dense diffused small blue or bluish-green punctures and well-developed medial anchor-shaped velvety black impunctate area; scutellum large, finely transverse striated; lateral margin in apical portion smooth, without microserrulations. White elytral pattern extremely reduced and presented by long sublateral band extending from subhumeral area to the apex ( Figs 36–37 ), or by two sublateral dots ( Figs 34–35 ) or strips ( Figs 38–39 ) in the middle part and at the apex. Abdominal sternum with isodiametric microsculpture. Aedeagus smoothly curved with dorsal groove extending from basal third to the short apex. Internal sac (in lateral view) situated at obtuse or right angle relative to aedeagus ( Figs 52–54 , 62–64 ), with relatively long flagellum, broad shield and flag, and very small medial tooth.
