Key to the species of Picia

1. Integument of funicle and segment 1 of antennal club clearly visible as covered with almost transparent, sericeous, seta-like scales; funicle moderately longer and finer, with segment 2 2.4 times longer than wide and 3–7 about 1.2 times longer than wide; disc of pronotum with more or less numerous concave scales with metallic reflection; at least first elytral interstria partly covered with shining scales with metallic reflection to apex; apical portion of tergite 8 with broadly blunted lip ( Fig. 10 ) .... P. sinuatocollis (Faust)

- Integument of funicle and segment 1 of antennal club barely visible as covered with dense, opaque, greyish brown, seta-like scales; funicle with segments 1 and 2 twice longer than wide and 3–7 about as long as wide; disc of pronotum with sparse concave scales with metallic reflection; on elytra only area around scutellum partly covered with shining scales with metallic reflection; apical portion of tergite 8 with rounded narrow lip ( Fig. 11 )........................................................................................................................2

2. Tarsi very elongate, with segment 5 at least 5.0 times longer than wide ( Fig. 7 ); pronotum slightly wider than long, distinctly narrower than elytra at base; humeri slightly protruding outwards ( Fig. 2 )................. .......................................................................................................................... P. mesopotamica (Tournier)
