Figs 13A–13B , 14A–14D Type material. Holotype : ♂ from Fazenda São Nicolau , Cotriguaçu , Mato Grosso , Brazil ( 9.840°S , 58.248°W ), 2–14.X.2010 , A.J. Santos leg. (UFMG 7696). Etymology. The epithet, to be treated as a Latin adjective, refers to the type locality. Diagnosis. The male of R. cotriguacuensis sp. nov . is similar to those R. tocantinensis sp. nov. and R. ruizi by having a short and wide embolus, projecting from the prolateral region of the tegulum and covered by a membranous layer ( Fig. 14C ), but differs by the more cylindrical shape of the embolus with a small apophysis at the apical region, as well as a simple and curved RTA directed towards the posterior region of the bulb ( Fig. 14D ).
