About Acanthoscurria natalensis Chamberlin, 1917
Acanthoscurria natalensis Chamberlin, 1917 is a dark-brown ground-dwelling tarantula species native to northeastern Brazil. This species looks almost identical to Acanthoscurria chacoana, but two consistent differences set them apart. First, A. natalensis has a longer embolus — the structure on male tarantulas that transfers sperm to females. Second, the keels on A. natalensis are less developed than those on A. chacoana.
