Myrmecotypus mazaxoides sp. nov. – a new ground-dwelling, carpenter ant-resembling sac spider species from the Bolivian orocline, with indirect evidence for species-specific mimicry (Araneae, Corinnidae, Castianeirinae)

Abstract

A new ant-resembling spider species of the subfamily Castianeirinae, Myrmecotypus mazaxoides sp. nov., from the Sub-Andean area of the Bolivian orocline is described. Adults of M. mazaxoides sp. nov. resemble the carpenter ant Camponotus cf. melanoticus Emery, 1894 and were observed on the ground of savanna-like habitats close to the entrances of formicaries of this ant. This study is the first to report a ground-dwelling species of Myrmecotypus O. Pickard-Cambridge, 1894; all the other species are arboreal.
