Redescription. Large-sized Cicindelina species, TL = 11.96–18.9 mm (mean = 15.7 mm, n = 202); females larger than males—TL = 13.2–18.9 mm (mean = 16.56 mm, n = 76) vs. 11.96–17.4 mm (mean = 15.17 mm, n = 126).
Top side dull metallic, bottom side dark with predominantly bluish tinge, as a rule glabrous, rarely with sparse pubescence.
Head glabrous, with large, protruding eyes; genae glabrous, shallowly striated; clypeus asetose, finely striated; frons, vertex, and occiput coarsely rugose; orbital plates with 5–11 furrows and two long setae in anterior and posterior positions (Figs 35–48, 51–60), rarely posterior setae doubled or tripled (Figs 49, 50, 61, 62). Antennae projected posteriorly over basal quarter or third of elytra; antennomere 3 the longest; antennomeres 1–4 metalliccoloured, antennomeres 3 and 4 with series of short, white, stout setae except apical ones; antennomeres 5–11 black, finely, and regularly pubescent. Mandibles black with metallic green and golden-cupreous tinge on the teeth base and wide white latero-basal portion. Maxillary and labial palpi metallic green with golden-cupreous, bronze-cupreous, or purple reflections. Labrum unidentate (Figs 63–82, 85–87, 90–95, 98–100), virtually tridentate (Figs 88, 89, 96, 101) or clearly three dentate (Figs 83, 84, 97, 102), pale with narrow brown apical margin and 3–11 long submarginal setae, covered by isodiametric microsculpture.
Pronotum from slightly longitudinal or sub-quadrate (Figs 103–135, 168–140)—PW/PL = 0.81–1.09 (mean = 0.99, n = 204) to clearly transverse (Figs 136, 137, 141, 142)—PW/PL = 1.1–1.22 (mean = 1.17, n = 34), coarsely wrinkled. Legs metallic, fore- and mid-trochanters with a single long apical seta; fore- and mid-coxae pubescent by short semierect white setae along anterior margin, hind coxae with 1–2, rarely with numerous setae in central part and a single apical seta; tarsomeres 1–3 of forelegs in males distinctly dilated; claws dark brown.
Elytra long, oval, narrower in males and wider in females, with numerous, dense-diffused, small metallic punctures as well as with lateral row of medium-sized setigerous pores and with rows of large metallic setigerous pores in humeral, sutural, and apical portions; shoulders from narrow and sloping (Figs 153–179, 183–189)—EW/ EHW = 1.41–1.86 (mean = 1.57, n = 204) to wide and rectangular (Figs 180–182, 190–192)—EW/EHW = 1.2–1.4 (mean = 1.28, n = 34); with (Figs 155–162, 165–179, 183–189, 193–212) or without (Figs 153, 154, 163, 164, 180–182, 190–192) subapical sinuate notch. White elytral pattern incomplete, in many cases extremely reduced, presented by a small apical portion of humeral lunule (sub-humeral spot), a basal portion of apical lunule (supra-apical spot), and a short apical (Figs 155–162, 165–172–179, 183–189, 193, 194, 197–201, 203–205, 207, 209–211), centro-apical (Figs 153, 154, 163, 164, 195, 196, 202, 206, 208, 212) or lateral (Figs 182, 192) portion of middle band, rarely by virtually complete middle band (Figs 180, 181, 190, 191).
Abdominal ventrites 3–5 with two pair setae, rarely with irregular row of 10–20 setae along anterior margin; anterior margin of sternite 6 in females with distinct notch and numerous short, stout brown setae.
Aedeagus with relatively thin, curved proximal portion and short apex; internal sac with large sh, ag, and mt as well as with long, thin fl; right dorso-lateral (DLR) and basal (B) humps undeveloped.
