Zootaxa 5679(4): 521-551.
Abstract
We describe the new genus Arboriticus gen. nov. and five new species of tarantulas from southeastern and northeastern Brazil: Arboriticus celsoi gen. nov. sp. nov. (type species) with male and female, A. petropolis gen. nov. sp. nov. with male, A. minor gen. nov. sp. nov. with male, A. giganteus gen. nov. sp. nov. with male and female, and A. maculatus gen. nov. sp. nov. with both male and female. Eupalaestrus spinosissimus Mello-Leitao, 1923 is transferred to Arboriticus gen. nov., making the new combination A. spinosissimus (Mello-Leitao, 1923). Eupalaestrus tarsicrassus Bucherl, 1947 is removed from the synonymy with Eupalaestrus spinosissimus and transferred to Arboriticus gen. nov. making the new combination A. tarsicrassus (Bucherl, 1947). The male of A. tarsicrassus is described for the first time. Pamphobeteus holophaeus Mello-Leitao, 1923 is removed from the synonymy with Eupalaestrus spinosissimus, transferred to Vitalius Lucas, Silva Junior & Bertani, 1993, and considered a junior synonym of Vitalius dubius (Mello-Leitao, 1923). The new genus is supported by phylogenetic evidence based on morphological and behavioral characters.
