Comments
According to Friese (1899), the type series of Epicharis obscura consists of two females from “São Leopoldina” (Santa Leopoldina, Brazil), one of them housed at NHMW. Additionally, Moure et al. (2007) indicated that the other female of the type series was housed at ZMB, but it is actually deposited at AMNH.
The forms E. maculata interrupta and E. maculata parvula were cited by Moure et al. (2007) as junior synonyms of E. obscura . Unfortunately, we cannot confirm this interpretation because the type specimens used by Schrottky were not found during the development of this research.
Most records of E. obscura are in the Brazilian States of São Paulo and Minas Gerais (Parana biogeographic domain sensu Morrone 2014), extending northward to Sergipe State. Considering the information cited above about the Schrottky’s type material, the record from Asunción ( Paraguay) remains doubtful.
