Pernotaris Voss, 1943: 232 (type species: Pernotaris squamiger Voss, 1943 [= Neopachytychius squamosus Hustache, 1939]). Type species. Neopachytychius squamosus Hustache, 1939. Diagnosis. Small (3.8-6.5 mm); vestiture of subcircular scales and setae; mandible and pharyngeal process long and narrow; rostral dorsal carinae present; antennal insertion distal; postocular lobes slightly developed; elytra oblong-oval. Relationships. Neopachytychius is the sister genus to Haversiella , andboth constitute the sister group to the five genera from the Tristan da Cunha-Gough islands. In a previous analysis based only on American genera ( Morrone 1997a ), Neopachytychius was considered to be the sister genus to Listronotus . Species included. Neopachytychius squamosus Hustache, 1939. Geographical distribution. Neotropical region, in Argentina, Bolivia, Chile and Uruguay ( Marvaldi 1994 ). Material examined. Neopachytychius squamosus (FIML, IADIZA, MACN, MHNS, MLP, MZFC).
