Emended diagnosis
The male of
Idiops carajas
(
Figs 13A–I
,
14
) 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
,
14D
), apophysis with a narrow rectangular apical branch (
Figs 13G–H
,
14C
) and by the presence of a lateral lamella that extends along the median portion of the embolus (
Figs 13E–F
). Differs from
I. petiti
by having the subapical portion of the embolus thickened in dorsal view (
Fig. 13D
) and the arrow-shaped apical end in retrolateral view (
Figs 13E–F
,
14E
). Females (
Fig. 13J–L
) 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
).
