Males of Arctosa sapiranga resemble Arctosa serii Roth & Brown, 1976 by the similar palea region, but differ by the large, bulging, membranous palea protuberance (Pp) of A. sapiranga ( Figs 29e , 32a ; Silva & Lise 2009 : fig. 6, missindicated as term ). Additionally, the combination of a triangular posterior arm and bulging retrolateral arm of the median apophysis distinguishes A. sapiranga from A. serii . Females of A. sapiranga are recognized from other neotropical species by a keel on median septum ( Fig. 30a, f, g, i ; Silva & Lise 2009 : fig. 9) like Arctosa perita ( Dondale & Redner 1983a : fig. 46) but differs from the latter by the pear-shaped head of spermatheca and very small vulval chamber ( Figs 30e , 33b ). Description. Male and female were described by Silva & Lise, 2009 . However, some remarks are presented here since somatic and genitalic details were passed over or misinterpreted. The median apophysis is not corkscrew shape ( Silva & Lise, 2009 ; fig. 6) but an excavated triangle ( Figs 28a, f , 31b, e ). Likewise, the structure misnamed as “term” ( Silva & Lise 2009 : figs 6, 12) is certainly a pronounced palea protuberance, diagnostic for males of A. sapiranga ( Figs 29e, h , 32a ) and not a terminal apophysis. The conical papilla on the female epigynal plate is visible and richly illustrated here ( Figs 33a, d ). Variation. As we observed, São Paulo female specimens shown variation in the atrium which was wider than the southern Brazilian specimens ( Figs 30g ‒j ). Male pedipalps present slight variation on posterior arm and retrolateral arm proportions ( Figs 28a–c ) when compared with São Paulo specimens ( Figs 28f–h ). Slight variations on the posterior arm and retrolateral arm of specimens from São Paulo show a smaller projection and a slightly wider base ( Figs 28f‒h ). Distribution. Brazil ( Rio Grande do Sul , and new records from the states of Tocantins , Distrito Federal, Goiás , Minas Gerais , São Paulo , and Paraná ) and Argentina (Misiones and Entre Ríos ) ( Fig. 66 ).
