Identification key to the subspecies of Cicindela (s. str.) coerulea
1(2) White elytral pattern undeveloped or strongly reduced (Figs 24–41). 12.5–16.0 mm...... C. coerulea coerulea Pallas, 1773
2(1) White elytral pattern well developed (Figs 89–106, 110–116, 155–166, 178–189, 215–232).......................... 3
3(4) White elytral pattern narrow with unconnected marks, humeral lunula divided on two isolated spots, rarely with virtually invisible medial portion, middle band in most specimens with short or long thin oblique branch without rounded apical extension, rarely with slightly developed it, marginal band undeveloped, rarely only marked (Figs 178–189). Aedeagus with relatively long basal portion (Figs 55, 56). 13.5–16.1 mm ...................... C. coerulea shantungensis Mandl, 1970
4(3) White elytral pattern medium-sized or wide with isolated marks, rarely with connected of some marks or with coupling all of them. Aedeagus with relatively short basal portion (Figs 42–54, 57, 59–64)....................................... 5
5(6) Medial band virtually transverse or slightly curved with very short oblique branch or without it (Figs 215–232).......... 9
6(5) Medial band distinctly sinuate with well-developed oblique branch (Figs 89–106, 112–116, 155–166).................. 7
7(8) White elytral pattern medium-sized, in most specimens with isolated marks (Figs 89–106), rarely with coupling middle band and apical lunula (Figs 112–114) or all marks connected by marginal band (Figs 115, 116), extremely rarely with undeveloped (Figs 110, 111) or clearly reduced (Figs 107–109) marks. Internal sac long and sharply rounded towards to ventral side so В distinctly or virtually contact with the aedeagus tube (Figs 117–132). 12.0– 15.4 mm ... C. coerulea nitida Lichtenstein, 1796
8(7) White elytral pattern often wide and all marks connected by marginal band (Figs 83, 155–159, 161, 163); in some specimens humeral lunula virtually separated from other marks (Figs 160, 164–166); rarely both humeral and apical lunulae unconnected with relatively long marginal band (Fig. 162). Internal sac short so В does not contact the aedeagus tube (Figs 167–170). 12.1–14.5 mm ............................................................... C. coerulea kaszabi Mandl, 1965
9(10) Labrum shorter, LW/LL = 2.3–2.44. Pronotum narrower, PW / PL = 1.36–1.4, with slightly rounded subparallel lateral sides (Figs 203–206). Middle band narrowly connected with apical lunula (Figs 215–220). 12.2–13.6 mm ...................................................................................... C. coerulea przewalskii Dokhtouroff, 1887
10(9) Labrum longer, LW/LL = 2.0–2.33. Pronotum wider, PW / PL = 1.41–1.57, with virtually straight, convergent at its base with the sides (Figs 207–214). All elytral spots separated from each other (Figs 221–232). 12.1–15.0 mm......................................................................................... C. coerulea grumi Tschitschérine, 1903
