A large species with elongate, unconstricted abdomen. Male with wing yellowish ( Fig. 38 , 134 ), female with wing yellow only anterobasally and with grey subapical cloud ( Fig. 135 ). The abdomen is dark brown, except for a pair of yellow maculae on tergite 2. The species resembles P. angustiventris and especially P. luridescens but differs from those by the absence of a fascia of golden pile along the mesonotal transverse suture. It also differs from most other Peradon species (except for some small species of the flavofascium group) in the smooth and shining bare median facial vitta ( Fig. 70 ). Male genitalia as in Fig. 273 . Distribution. Known from the Misiones province in northeastern Argentina and from the Santa Catarina and Sao Paulo states in southern Brazil.
