Emended diagnosis

The male of Idiops carajas   ( Figs 13A–I View Fig , 14 View Fig ) differs from the other Neotropical species, except I. petiti   , by the palpal tibia having spines concentrated on the basal half of the retrolateral depression ( Figs 13C View Fig , 14D View Fig ), apophysis with a narrow rectangular apical branch ( Figs 13G–H View Fig , 14C View Fig ) and by the presence of a lateral lamella that extends along the median portion of the embolus ( Figs 13E–F View Fig ). Differs from I. petiti   by having the subapical portion of the embolus thickened in dorsal view ( Fig. 13D View Fig ) and the arrow-shaped apical end in retrolateral view ( Figs 13E–F View Fig , 14E View Fig ). Females ( Fig. 13J–L View Fig ) are distinguished from congeners, except I. petiti   , by having the spermathecae with a sclerotized trapezoidal base. Differs from I. petiti   by the ducts having a thickened basal half and shorter apical half and by the rounded receptacles, separated from the ducts by a strong constriction ( Fig. 13L View Fig ).
