Biogeography of New World Tarantulas

Four new species of mygalomorph spiders (Araneae, Halonoproctidae and Theraphosidae) from the Colombian Pacific region (Bahía Solano, Chocó)

“…While a few groups of trapdoor spiders can perform short-range ballooning ( Bristowe 1939 ; Coyle 1983 , 1985 ; Coyle et al 1985 ; Ferretti et al 2013 ; Rossi et al 2021 ), mygalomorph spiders are primarily terrestrial and relatively sedentary ( Raven 1980 , 1985 , 2010 ; Pérez-Miles and Perafán 2017 ). Consequently, many groups have restricted geographic distributions and high levels of endemism, which makes them a highly informative group for conservation studies, environmental monitoring, and biogeography research ( Raven 2010 ; Foelix 2011 ; Ferretti et al 2012 , 2014 ; Perafán et al 2020 ). In this way, many unexplored areas, especially in megadiverse regions, have a high potential for new mygalomorph species to be discovered.…”
