Abstract
A new genus and two new species of ant-resembling castianeirine spiders are described from the Neotropics. Grismadoxgen. nov. comprises four species: Grismadox bauerisp. nov., and Grismadox mazaxoides (Perger & Duperré, 2021) comb. nov. from Bolivia, and Grismadox karuguasp. nov. (type species) and Grismadox mboitui (Pett, 2021) comb. nov. from Paraguay. All species are diagnosed and the new species are described and illustrated. Available ecological data suggests that all four species are primarily epigeal and inhabit Grassland and savannah type habitats.
Highlights
The subfamily Castianeirinae (Araneae, Corinnidae) is represented by slender spiders generally regarded as good examples of Batesian or Müllerian mimics of ants (Cushing 2012; Perger and Rubio 2020; Perger 2021)
The subfamily is cosmopolitan and the New World has a rich fauna of accurate ant mimics with similar coloration to their ant models and adaptations to the typical body plan
All Grismadox species for which we have detailed records were collected in savannah-like habitat
Summary
The subfamily Castianeirinae (Araneae, Corinnidae) is represented by slender spiders generally regarded as good examples of Batesian or Müllerian mimics of ants (Cushing 2012; Perger and Rubio 2020; Perger 2021). New World endemic genera include Mazax O. Pickard-Cambridge, 1894 and Psellocoptus Simon, 1896 (World Spider Catalog 2021). Pickard-Cambridge, 1895 are recorded from the New World, but have intercontinental distributions, being registered from the Oriental Region, and the former two from the Afrotropical realm (Haddad 2013; World Spider Catalog 2021). Apochinomma may be restricted to the Afrotropical realm, with Neotropical representatives likely misplaced (Rubio and Arbino 2009)
