6. Elytral intervals 2, 4 and 6 dark for their entire length, remaining intervals reddish or pale. Male and female genital structures ( Figs 10, 15 , 20, 25 ) ....................................... ..................................................................................... Hypera striata (Boheman, 1834)

­ Elytra with dark parts on basal two thirds of interval 1, apical quarter of interval 2, basal third of interval 3, apical half of interval 4, small apical part of interval 5 and all interval 6; remaining parts reddish. Male and female genital structures ( Figs 7, 12 , 17, 22 ) ............................................................................................... Hypera kayali sp. nov.

7. Elytra covered with long, strongly projecting setae.... Hypera tenuirostris ( Petri, 1901)

­ Elytra with short, recumbent setae. .............................................................................. 8

8. Pronotum strongly oblique, base of elytra distinctly wider than pronotum ( Figs 27, 28 ), size: 3.5–5.0 mm; dorsum grey to cupreous brown................................................. ...................................................................................... Hypera meles (Fabricius, 1792)

­ Smaller and more gracile, (size: 3.6–4.2 mm), base of elytra slightly wider than pronotum, pronotum strongly oblique, but somewhat less expanded than in H. meles ( Figs 29, 30 ) ...................................................................... Hypera fornicata (Penecke, 1928)
