Figure 1. Distribution map of sample sites and effort. Relief map of the Maroni Basin (delimited in black) showing 83 sampling points (red dots) of specimens collected. Names of main tributaries are indicated in blue and main sampling locations are in black. Red dot size refer to sampling effort in each site. The map was reconstructed using raster images and shapefiles obtained from HydroSHEDS (Lehner, Verdin, & Jarvis, 2008) project website (http://www.worldwildlife.org/pages/hydrosheds) and the R packages raster v2.9.5 (Hijmans, 2019), rgdal v1.4-8 (Bivand, Keitt, & Rowlingson, 2019), shapefiles v0.7 (Stabler, 2013), and mapplots v1.5-1 (Gerritsen, 2018).
