Epyris rotundus sp. nov. and Epyris cochlear sp. nov., from southern Brazil, are described and illustrated. Epyris longus Corrêa & Azevedo, 2002, E. argentinicus Evans, 1969, E. angustatus Evans, 1969, E. perpolitus Evans, 1969, E. parallelus Evans, 1969, E. distinctus Corrêa & Azevedo, 2002, E. variatus Corrêa & Azevedo, 2002, E. jugatus Evans, 1969, E. intermedius Evans, 1969 and E. depressigaster Evans, 1966 are recorded for the first time to Paraná, Brazil.


INTRODUCTION
Epyris Westwood, 1832 belongs to subfamily Epyrinae, with about 64 species in the Neotropical region.There are 29 species recorded to Brazil, from the states of Amapá, Pará, Mato Grosso, Espírito Santo, Rio de Janeiro, Paraná and Santa Catarina.Two species were recorded to Paraná State, E. crassifemur Evans, 1969 andE. marcapata Evans, 1969.Thirteen species from Paraná are recognized, two of them described as new and ten recorded for the first time to the state.
The material examined was provided by the Coleção de Entomologia Padre J. S. Moure, Universidade Federal do Paraná, Brazil (DZUP).The nomenclature of integument sculpture follows HARRIS (1979) and the terminology generally EVANS (1969).Main measurements and indices used are: DAO, diameter of anterior ocellus; distance from posterior ocellus to vertex crest; HE, height of eye; LFW, length of fore wing; LH, length of head; OOL, ocello-ocular line; VOL, vertex-ocular line; WF, width of frons; WH, width of head; WOT, width of the ocellar triangle.
Distribution.Tucumán, Argentina; Santa Catarina and it is recorded for the first time to Paraná, Brazil.widened behind.Scutellar pits elliptical, distant each other 1.56x its length, joined by a very narrow furrows.Propodeal disc 1.32x as wide as long; median carina complete, discal carinae straight, slightly longer than half of the disc and slightly convergent behind, space between discal carinae striate; lateral of propodeum and declivity microstriate.Mesopleuron with a complete and large fovea with a deep triangular central pit.Mid tibiae spinose.Metasoma: polished up to third segment and weakly coriaceous behind.
Remarks.Epyris rotundus belongs to tricostatus group and runs to E. marcapata Evans, 1969 in the key by EVANS (1969), but it has paramere with rounded apex, aedeagus as high as cuspis; E. marcapata has paramere with apex truncate and aedeagus shorter than cuspis.
Etymology.Specific name refers to the rounded apex of paramere.
rufipes species group
Distribution.Rio de Janeiro, Santa Catarina; it is recorded for the first time to Paraná, Brazil.
Variation.The paramere can be longer than in the type and the longest females show texture stronger than in the small specimens.
Distribution.Tucumán, Argentina; Santa Catarina and it is recorded for the first time to Paraná, Brazil.
Variation.The paramere and cuspis are longer than those of type series.
Variation.In relation to the type series, cuspis can be bigger, aedeagus can have the same length of paramere, paramere in lateral view can be wider and slightly arched, females can be slightly more coriaceous and the scutellar pits separated by little less than twice their own diameters.
