Holotype male, France, Provence-Alps-French Riviera, Bois de Bouis near Vidauban, Malaise trap, 20.04.2015, P. Withers leg. (CEIG). Etymology. The species is named in honour of our friend the late Phil Withers who collected the holotype in France. Distribution. France. Comments. The peculiar shape of aedeagus, parameres and gonostyles in males of S. withersi makes it impossible to confuse this species with any other currently known member of the genus Schizohelea.
