Key to subfamilies and tribes of Melyridae

1. Surface of body covered with double pubescence, short adpressed and long semi-erect or erect hairs. Ventral sides of tarsomeres with short and sharp setae (Astylinae Majer, 1987)........................................................... 2

- Surface of body covered with adpressed or semi-erect pubescence, lacking erect hairs. Tarsomeres lacking sharp setae, bare or pubescent ventrally ( Melyrinae Leach, 1815 )............................................................... 3

2. Body short, parallel and suboval, slightly convex, penultimate antennomeres transverse. Legs short and strong.......................................................................................... Arthrobrachini Majer, 1987

- Body elongate, evenly widened posteriorly, slightly flattened, penultimate antennomeres longitudinal or equilateral, never transverse. Legs long and slender............................................................ Astylini Pic, 1929

3. Elytra evenly covered with distinct adpressed hairs, lacking carinae. Tarsomeres pubescent ventrally..... Cerallini Pic, 1929

- Elytra covered with extremely short semi-erect dense pubescence, canaliculate. Tarsomeres bare or with strong setae on ventral side................................................................................................ 4

4. Penultimate antennomeres distinctly triangular with sharp distal edges. Elytral punctation irregular. Lateral sides of pronotum with singular or double thin margination, not vertical. Surface of pronotum with small irregular punctation. Tarsomeres bare or with sparse short semi-erect hairs in periphery of tarsomere............................. Melyrini Kiesenwetter, 1863

- Penultimate antennomeres oval-triangular with rounded edges. Elytral with three regular rows of punctures between longitudinal carinae. Pronotum with vertical lateral sides bordered with strong carinae. Surface of pronotum with strongly pronounced foveolate punctation. Tarsomeres with strong semi-erect dark setae on ventral side................. Amelyrini trib. nov.
