Prionocera revisited (Diptera: Tipulidae)

The synonymy of Prionocera chosenicola Alexander with Prionocera tjederi Mannheims is discussed and the following syn. nov. is proposed: Prionocera mannheimsi Savchenko=Prionocera byersi Brodo. Prionocera parrii (Kirby) remains a nomen dubium. Significant range extensions are noted for Prionocera dimidiata (Loew), Prionocera ominosa (Alexander), Prionocera oregonica Alexander, Prionocera pubescens Loew, Prionocera ringdahli Tjeder, Prionocera serricornis (Zetterstedt), Prionocera subserricornis (Zetterstedt), and Prionocera turcica (Fabricius).
