Redescription of Tingiometra Heiss, Golub & Popov, 2015

Based on the type species burmanica ( Fig.1 ), the genus is characterized by following essential features which are also shared by the new species placed in Tingiometra .

Head very long and rather narrow, dorsally without tubercles, clypeus crest-like, anteocular part distinctly longer than postocular part; eyes placed at a considerable distance from base of head, approximately 0.36–0.42 of the total length of the head.Antennae 4-segmented, long and slender; second antennal segment is longest; bucculae high and very short, occupying only apical part of the lower head surface, closed anteriorly, surrounding base of labium in front and sides.

Pronotum narrow anteriorly and wide posteriorly, bell-shaped in outline, its anterior and posterior margins sinuate, anterior margin without elevated areolate structure (hood, vesicula), posterior margin not produced as lobe and not overlapping scutellum; disk with a longitudinal bilobate median carina, anterior part much shorter than posterior one.

Hemelytra with corium divided by longitudinal carinate veins into costal, subcostal, discoidal, and sutural areas; discoidal area very wide and divided by longitudinal and transversal carinate veins into several large cells containing many small areolae; vein R + M separating subcostal and sutural areas, distally bifurcated into R and M. Clavus separated from corium by a commissure.

Legs long and slender.
