A NEW SPECIES OF THE GENUS Macrinus SIMON, 1887 (ARACHNIDA: ARANEAE: SPARASSIDAE) FROM NORTHERN BRAZIL
Abstract
The genus Macrinus Simon currently includes six species occurring mostly in South America, with records from the island of Tobago, Venezuela, Guyana, Ecuador, Bolivia and Brazil. A single species is found in the Mohave desert in California, USA. In this paper, I describe a new species of Macrinus based on a single female from the state of Pará, northern Brazil. The new species can be easily distinguished from its congeners by the shape of the median septum in the epigyne resembling a chess pawn. In addition, I provide new records for M. succineus Simon, M. pollexensis (Schenkel) and M. jaegeri Rheims and an updated distribution map for all South American species.
