In the UK we only have two species of Polyporivora - P. ornata and P picta, but I don't have Chandler's (expensive) key work. Can anyone say how to tell these two species apart?

Abdomen with T2 often bearing a pair of small grey spots dorsally; T3-5 with triangular black basal markings, that on T3 extended to hind margin => Polyporivora picta - Thorax with dark median stripe narrowed behind and ending well short of scutellum, fused in front with lateral dark markings to form tridentate pattern; scutellum without black marking. Abdomen with T2 entirely black dorsally, T3 broadly black in middle dorsally and T4-5 with basal black bands => Polyporivora ornata Jan Willem Edited by Jan Willem on 23-11-2007 08:11
