* ) In the original description of P. parananus , SIJΑ*©Ρ (1882) lists the type locality simply as ‘South America, ( Parana )’.The name Parana could be associated with a variety of geographic and political entities in the 19 th century.While GUඌτΑΓඌƟΝ et al. (2016) followed GUḖƟ*©ǤUι*úඏ (1972) and BĿΑർĸඐ*úĿĐ*ú*© (1944 interpretingin) SIJΑ*©Ρ’s (1882) locality as referring to Paraná, Entre Ríos , Argentina , however, we find it more likely this is actually in reference to Paraná State , Brazil (NιĿඌඌƟΝ & HǍ*°*úĸ 2020), and have updated the checklist to the South American Platynectes species. Distribution. This species has been recorded across Guyana , Suriname , and French Guiana. Remarks. The species was previously reported from Brownsberg Nature Park in Suriname . The Kabalebo specimens represent a new locality record in Suriname .
