Abstract

CUEZZO, MARÍA GABRIELA; LIMA, AUGUSTO P. DE  and  SANTOS, SONIA B. DOS. Solaropsis brasiliana, anatomy, range extension and its phylogenetic position within Pleurodontidae (Mollusca, Gastropoda, Stylommatophora). An. Acad. Bras. Ciênc. [online]. 2018, vol.90, n.3, pp.2753-2765.  Epub July 19, 2018. ISSN 0001-3765.  https://doi.org/10.1590/0001-3765201820170261.

A detailed anatomical revision on Solaropsis brasiliana (Deshayes 1832) has been carried out. New characters on shell, anatomy of soft parts, and a review of the genus distribution in South America, as well as clarification on S. brasiliana distributional area are provided in the present study. Solaropsis brasiliana is diagnosed by its globose, solid, and hirsute shell, with periphery obsoletely angular, bursa copulatrix with a thick, long diverticulum, a thick, long flagellum and a penis retractor muscle forked, with the vas deferens passing through it. This compiled information was used to test the phylogenetic position of S. brasiliana within South American Pleurodontidae through a cladistics analysis. In the phylogenetic hypothesis obtained, S. brasiliana is sister group of S. gibboni (Pfeiffer 1846) and the monophyly of the genus Solaropsis Beck is also supported. Here, we sustain that the distribution of S. brasiliana is restricted to Brazil, inhabiting the States of Rio de Janeiro, Espírito Santo, Bahia and Minas Gerais.
