( Fig. 4 View FIGURE 4 )

Material. Holotype — PIN, No. 5890/13. Isolated elytron, left . Paratypes: PIN, No 5890/12, part and counterpart, and PIN, No 5890/15, partially preserved isolated elytra.

Locality and horizon. Alisa locality, Nidym Formation, Lower Triassic.

Diagnosis. Elytron of middle size, carinated, bearing at least 5 veins and one scutellar striole. Cells roundish, or rarely slightly oval-shaped, reinforced with dark maculae. Elytral surface covered with dense tubercles. Vein 2 drows close to epipleural carina near humerus; Vein 3 very short, as long as combined length of 4 cells. Cells between veins are placed unevenly, without forming well-defined longitudinal rows.

Description. Epipleural carina widening at basal third, then narrowing towards elytral apex. Vein 2 drows located close to epipleural carina near humerus then widens posteriorly; Vein 3 very short, as long as combined length of 4 cells, veins 3 and 4 are close together. Epipleuron without cells, in the field II up to 3 rows of cells, field III — 3 in central part and 4 in basal part, IV —1 row of cells. There are more than 34 cells in a row.

Measurements (in mm). Holotype —Elytron length 8.6, width 3; paratype PIN, No. 5890/15—length of the preserved part of the elytron 6.9, width 2.6.

Etymology. After Latin “ brevis ”—small, and “ cellularis ”—due to lattice pattern formed by cells.

Remarks. The specimen was attributed to the genus Tatarocupes for having at least 6 rows of cells between two veins, closest to sutural margin.

Comparison. Differs in having a single row of cells between veins 3 and 4 (at least near the elytral base).
