The genus
The European species are usually found in wetlands and water banks in low and middle elevations (
The tribe
Material used of this study is deposited in the following collections:
Genitalia were dissected, cleared in a 10% KOH solution, washed in water, and placed in glycerol on slides for further study. Female genitalia were stained with chlorazol black. Measurements were recorded as follows:
Representatives of the genus
Body elongate-oval, with sides parallel (Fig.
Immature stages and habitus of adult species of
Head partially withdrawn into prothorax (Fig.
Anterior margin of pronotum weakly, broadly emarginate (Figs
Mesoventrite 1.3× longer than its width at the level of mid coxae (Figs
Trochanters simple, subtriangular, without projection (figs 7E, 9D). Tibiae slightly expanded apically with one apical spur on forelegs, and two in mid and hind legs. Tarsi consisting of four tarsomeres, second tarsomere truncate apically; tarsal claws cleft apically (Fig.
Abdomen in both sexes with 6 ventrites (Fig.

– | Pronotum with posterior corners not distinctly pointed, with an angle around 90° (Figs |

4 | Body entirely rufous, sometimes with darker scutellar shield (Fig. |
|
– | Body testaceous with small transverse macula at base of pronotum just above scutellar shield, scutellar shield dark, elytra with single dark brown to black, longitudinal macula on elytral suture around middle of elytra (Fig. |
