First record of Aenigmarachne Schmidt, 2005 (Araneae: Theraphosidae) from Colombia, with the description of a new species and the first described female

The previously monotypic genus Aenigmarachne Schmidt, 2005, known only from a single male specimen collected presumably in Isla el Coco, Costa Rica, is reported here for the first time in Colombia, with the description of a new species based on male and female specimens. Thus, we expand the known geographic range of the genus and enhance our understanding of Theraphosinae diversity in northern South America and Colombia.

Additionally, we provide detailed observations on the urticating setae in the species and discuss aspects of its natural history.
