Sub-fossil material.
Site Ustyanka-1 (2013), section II, sample 2 (depth 5.00- 5.20 m) - fragment No. 2-13 (right elytron) (Fig. 4k View Figure 4 ); site Ustyanka-1 (2020), section I, sample 16 (depth 4.76-4.82 m) - fragment No. 10 (left elytron) (Fig. 4h View Figure 4 ); ibidem, sample 19 (depth 4.94-5.00 m) - fragments No. 13 (right elytron) and No. 14 (base of left elytron); ibidem, sample 20 (depth 5.00- 5.06 m) - fragment No. 21 (right elytron) (Fig. 4i View Figure 4 ); ibidem, sample 22 (depth 5.12-5.19 m) - fragment No. 2 (right elytron) (Fig. 4j View Figure 4 ); ibidem, sample 25 (depth 5.30-5.35 m) - fragment No. 6 (pronotum) (Fig. 4g View Figure 4 ).
Fragment description.
Sample 16 (2020), No.10 left elytron, black with weak violet-blue metallic lustre, narrow, ovoid narrowed distally with narrowed and rounded apex and yellow spot near suture; suture thin and indistinct, scutellum emargination wide; punctures fine and sparse, hardly visible, sizes: 0.6 mm at base near humerus, 0.86 mm at widest part near apices, length 2.64 mm; sample 2 (2013), No.2-13 right elytron, apparently looks similar to left one (mentioned above), yellow spot on apex slightly transverse, sizes: 0.68 mm at base near humerus, 0.94 mm at widest part near apices, length 2.95 mm; sample 20 (2020), No.21 right elytron, in comparison with the other fragments relatively more strongly narrowed at apex, with round yellow spot near suture, sizes: 0.62 mm at base near humerus, 0.93 mm at widest part near apices, length 2.76 mm; sample 22 (2020), No.2 right elytron, black with a weak blue metallic lustre, narrow, almost completely not widened, narrowed and rounded distally, apex completely yellow, punctures fine and sparse, indistinct, suture thin, indistinct, scutellum emargination wide, sizes: 0.69 mm at base near humerus, 0.86 mm at widest part near apices, length 2.95 mm; sample 25 (2020), No.6 pronotum, transverse, 1.5 times as wide as long, convex lengthwise and slightly depressed at basal angles, anterior side weakly protruding, posterior with distinct emargination above scutellum, sides evenly rounded, with thin margination, surface finely and densely punctured, black with a weak green-blue metallic lustre, sizes: width 1.44 mm, length 0.93 mm.
Discussion.
It is difficult to refer the fragments from the deposit to one of the known species of the genus Ebaeus Erichson due to the considerably larger size of elytra and pronotum, and their colouration with distinct violet-blue metallic lustre. Probably, this is one of independent and undescribed species which could be defined if male elytra are found.
