Polistes bischoffi Weyrauch, 1937

It is very difficult to separate females of this species from P. biglumis . Other species differ by short erect hairs on mesoscutum. Males are similar to P. gallicus , which has clypeus convergent below and temples strongly convergent behind eyes, but both species differ by hairs on mesoscutum and colouring of antennae – P. bischoffi has antennae distinctly darkened above, while P. gallicus has antennae orange beyond segment 3.

The newest member for the fauna of both countries, which is known from the southern parts of the Czech Republic and from northwest and west Slovakia (see DVOŘÁK et al. 2006 for summary).
