Records of Spiders (Arachnida: Araneae) of the Parque Estadual Mata São Francisco, Paraná, Brazil

Abstract

A list of spider species recorded from the Parque Estadual Mata São Francisco, Paraná, Brazil was compiled based on 7,942 specimens, of which 2,872 are adults (36.15%) and 5,071 are juveniles (63.85%). Adults were identified as belonging to 45 families, 140 genera and 209 species and morphospecies (101 nominal species and 108 morphotypes). Forty-one species were recorded for the first time from the state of Paraná, most of them belonging to Araneidae (14), Oonopidae (4), Theridiidae (4), and Uloboridae (3). Conifaber guarani Grismado, 2004 and Oonops nigromaculatus Mello- Leitão, 1944 were recorded for the first time from Brazil. These results place Paraná as the sixth state with the highest number of records of spiders from Brazil, currently 465 species. This study increases in 10% the number of species recorded from Paraná, and the Atlantic Forest fragment becomes one of the most well sampled areas in the state, with 20% of all known species in Paraná.

Spider diversity (Arachnida: Araneae) in Atlantic Forest areas at Pedra Branca State Park, Rio de Janeiro, Brazil

“…Our study uses standardized techniques alongside statistical tools to estimate the spider fauna in forested areas in Rio de Janeiro state. About Brazil as a whole, we can find studies documenting the fauna of spiders presenting a simple list of species (e. g. Buckup et al 2010 , Brescovit et al 2011 , Chavari et al 2014 , Melo et al 2014 , Nogueira et al 2014 ), and others that consider statistical tools to analyze the dynamics of the fauna (e. g. Álvares et al 2014 , Indicatti et al 2005 , Candiani et al 2005 , Raizer et al 2005 , Nogueira et al 2006 ).…”

First record of Bertrana striolata (Arachnida: Araneae: Araneidae) in Amazonian Ecuador

“…Bertrana striolata Keyserling, 1884 has the broadest geographic range among all species of the genus, with records in Costa Rica, Panama, Colombia, Ecuador, Peru, Guyana, Brazil, Bolivia, and Argentina [1]. Despite its large range, B. striolata is known from broadly scattered localities, and most records come from Panama and Brazil [1][2][3][4][5][6][7][8][9][10][11][12]. In western Amazonia, B. striolata remains known from just four localities: one in Colombia (Bueva Vista) and three in Peru (Tingo María, Dantas La Molina, Atalaya-Río Carbón) [1].…”
