Polistes associus Kohl, 1898

Females are very similar to P. nimphus . In P. associus the last sternum is usually reddishbrown with lighter apical spot. According to J. Gusenleitner (pers. comm.), Austrian populations have the last sternum coloured similarly to P. nimphus and differ by reduced black stripe on clypeus. Males are similar to P. gallicus and P. bischoffi by having clypeus convergent below and temples convergent backwards, but only P. associus has longitudinal ridges on clypeus.

South-European species of lower altitudes, which occurs in Hungary and eastern Austria. The only published record from Slovakia was from an old museum collection ( DVOŘÁK 2005). Not known from the Czech Republic.
