Indostola Medvedev, 1991

Indostola Medvedev, 1991:557 (original description). Type species: Indostola pulchella Medvedev, 1991 (by original designation).

Diagnosis. The genus Indostola is characterized by eyes not divided into upper and lower parts by genae; eyes in lateral view not diminished to narrow transverse stripe of facets in lower part ( Figs 27–28 ) as in Stenosis Herbst, 1799 (see MEDVEDEV 1994, Fig. 25 ); pronotum longer than wide and distinctly narrower than head; tempora almost parallel for one eye length behind posterior margin of eyes.

Remarks. The illustration of the elytra in MEDVEDEV (1991: Fig. 1 ) is not accurate, as in fact the elytra are narrowing gradually to elytral base (see Fig. 1 in this paper).
