Differential diagnosis. Apterodela kazantsevi is easily distinguished from A. bivirgulata by the deep subapical notch (Figs 201, 211 vs. Figs 155–162, 165––179, 183–189) as well as by the shape of aedeagus (Figs 222, 233 vs. Figs 214–219, 228–231) and internal sac (Figs 239, 246, 253, 260 vs. Figs 238, 245, 252, 259). Apterodela kazantsevi is readily distinguished from related A. latissima sp. nov. (only by males) by the longer labrum LW/LL = 1.67–2.0 (mean = 1.89) vs. 1.97–2.38 (mean = 2.17), the narrower elytra EW/EHW = 1.44–1.69 (mean = 1.58) vs. 1.71–1.78 (mean = 1.75) with less sinuate lateral margins and longer subapical notch (Fig. 201 vs. Figs 199, 200), the less convex body TL/BH = 4.15–4.59 (mean = 4.31) vs. 4.0–4.28 (mean = 4.14), and the shape of aedeagus (Fig. 222 vs. Fig. 223). Apterodela kazantsevi is clearly separated from A. lobipennis by the longer labrum, especially in females LW/LL = 1.67–2.0 (mean = 1.89) vs. 1.82–2.40 (mean = 2.05) in males and 1.22–1.53 (mean = 1.31) vs. 1.50 –2.00 (mean = 1.73) in females, the narrower pronotum HW/PW = 1.39–1.6 (mean = 1.51) vs. 1.3–1.52 (mean = 1.4), the wider elytra with longer and deeper subapical notch (Figs 201, 211 vs. Figs 193–198, 203–210), by the shape of aedeagus (Figs 222, 233 vs. Figs 220, 221, 232) and internal sack (Figs 239, 246, 253, 260 vs. Figs 240, 247, 254, 261). Apterodela kazantsevi is differentiated from A. alopecomma sp. nov. by the smaller size TL = 14.7–15.6 (mean = 15.2) mm vs. 15.5–16.7 (mean = 15.98) mm, flatter body TL/BH = 4.15–4.59 (mean =4.31) vs. 3.93–4.19 (mean = 4.04), wider head HW/PW = 1.39–1.6 (mean = 1.51) vs. 1.24–1.33 (mean = 1.29), glabrous scape (Figs 54, 55 vs. Figs 57, 58), shape of labrum (Figs 93, 98 vs. Figs 95, 100), wider elytra EL/EW = 1.57–1.74 (mean = 1.66) vs. 1.72–1.78 (mean = 1.75), and the shape of aedeagus (Figs 222, 233 vs. Figs 224, 234) and internal sac (Figs 239, 246, 253, 260 vs. Figs 241, 248, 255, 262).

Redescription. TL = 14.7–15.6 mm (mean = 15.2 mm, n = 4) in males, 15.2–18.1 mm (mean = 16.8 mm, n = 5) in females (Fig. 25); body flat, slightly convex, in males weaker than in females—TL/BH = 4.15–4.59 (mean = 4.31, n = 4) vs. 3.53–3.84 (mean = 3.75, n = 5) (Fig. 276; Table 1).

Head metallic bronze with light bluish-green and golden-cupreous lustre on clypeus, frons and anterior edge of genae, and bright purple-cupreous reflection along sides of orbital plates; glabrous, coarsely wrinkled, with thin dense frontal furrows; orbital plates with 10–11 deep furrows; vertex widely concave, in anterior portion with wide U–shaped depression especially in females; HW/PW = 1.39–1.6 (mean = 1.51, n = 10) (Figs 274, 275, 278). Antennae projected posteriorly over basal third of elytra; antennomeres 1–4 metallic greenish-bronze, bronze or cupreous with golden-cupreous or greenish-gold tinge; scape besides single apical seta glabrous; antennomere 3 with three–five while antennomere 4 with two–four stout white setae except apical ones (Figs 54, 55). Labrum transverse, LW/LL = 1.67–2.0 (mean = 1.89, n = 5) in males, 1.22–1.53 (mean = 1.31, n = 5) in females, unidentate with long, stout apical tooth in females and short tooth in males and 4–9 submarginal setae (Figs 93, 98).

Thoracic segments deep bronze, glabrous, coarsely rugose (Fig. 149). Legs metallic green with bronze-cupreous or purple-cupreous reflections.

Elytra purple-bronze with cupreous tinge, with numerous, dense diffused, small violet-green or bluish-green punctures and with humeral, subsutural, and subapical rows of large golden-green setigerous pores; flattened, EL/ EW = 1.57–1.74 (mean = 1.66, n = 12); with wide and deep subapical sinuate notch in both sexes. Shoulders narrow, sloping, EW/EHW = 1.44–1.69 (mean = 1.58, n = 7) in males, 1.66–1.86 (mean = 1.78, n = 5) in females; scutellum bronze, large; humeral group of series umbilicata consists of 5–7 large setigerous pores (Fig. 149); epipleura bronze, broad. White elytral pattern presented by the small, oval sub-humeral spot and short, comma-shaped, indistinctly oblique apical portion of middle band, supra-apical spot in males entirely absent, in females virtually invisible small, narrow, stripe-shaped (Figs 201, 211).

Abdominal ventrites glabrous, black with a light bluish or violet tinge along anterior margin.

Aedeagus medium-sized, EL/AL = 2.14–2.26 (mean = 2.2, n = 2), with short, slightly broadened apex terminating in indistinct knob and extended lateral flanks (Figs 222, 233). Internal sac with long straight mt, large ag, ll, and sh-ar, distinct guide for f, which placed across DA and VLL, large protruding VA and only marked both BLL and BLR (Figs 239, 246, 253, 260).
