Key to Tingiometra species

1 Discoidal area of hemelytra with three large cells filled with many small areolae. Head about 3.6 times as long (total length: from apex of clypeus to posterior margin) as width of head across eyes. Body length 3.1 mm. Fig. 1 ...................................................................................................... burmanica Heiss et al.

- Discoidal area of hemelytra with five large cells filled with many small areolae. Head 1.65–2.55 times as long (total length) as width of head across eyes............................................................................... 2

2 Antennae rather short: 0.85–0.90 mm all segments together. Costal area of hemelytra comparably wide, with 2–3 rows of areolae at the anterior part of length. Subcostal area narrow, with 3–4 rows of areolae in most part of its length and with 5–6 rows in the apical quarter only. Smaller: body length 2.20–2.38 mm. Fig. 12-13 ......................... yuripopovi sp. nov.

- Antennae very long: 1.54–1.56 mm all segments together. Costal area of hemelytra very narrow, with one row of areolae. Subcostal area wide, with 7–11 rows of areolae. Larger: body length 3.10–3.13 mm ................................... 3

3 Body narrower, 2.09–2.42 times as long as wide, lateral margins of hemelytra not very rounded. Subcostal and discoidal areas of hemelytra with 6–7 and 18–22 rows of areolae at their widest parts respectively. Body length 3.1 mm. Figs 2–10 ........................................................................................... pankowski i sp. nov.

- Body wider, 1.79 times as long as wide, lateral margins of hemelytra very rounded. Subcostal and discoidal areas of hemelytra with 10–11 and 17 rows of areolae at their widest parts respectively. Body length 3.13 mm. Fig. 11 ....... secunda sp. nov.
