Attacobius blakei Bonaldo & Brescovit, 2005: 51, figs 11–13 (♂ holotype from Estação Científica Ferreira Penna, Caxiuanã National Forest, Melgaço, Pará, Brazil, 1-11.VI.2001, A.B. Bonaldo et al. leg. (MPEG 0152), re-examined.
Diagnosis. Females of A. blakei are similar to those of A. demiguise n. sp. and A. uiriri (Figs 13, 15, 16, 18) by the medially interrupted epigynal ventral plate. They can be distinguished from those of A. demiguise n. sp. by the absence of secondary spermathecae and from those of A. blakei by the narrower copulatory ducts (Figs 16–18).
