Figs 19–21View FIGURES 19–24; Map 2

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 0152View Materials), re-examined. 

Diagnosis. Females of A. blakei  are similar to those of A. demiguise  n. sp. and A. uiriri  ( Figs 13, 15, 16, 18View FIGURES 13–18) 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 16–18View FIGURES 13–18).

Description. Male. Described by Bonaldo & Brescovit, 2005: 51, figs 11–13.
