Etymology: the specific name refers to the femur of the third leg that has a dilation in the basal part.
Diagnosis: Females of Idiops dilatatus sp. nov. can be distinguished from other species within the genus by the following sets of characters: Presence of bristles on the ocular tubercle ( Figure 1A, C View Figure 1 ); internal dilation of the femur (fe) on the third pair of legs ( Figure 2A View Figure 2 ); inferior tarsal claw (ITC) and superior tarsal claw (STC) each with basal teeth on either side ( Figure 2B View Figure 2 ); Base of the spermatheca little sclerotized, receptacles with a rounded shape, short ducts and almost as wide as the receptacles, are oppositely curved ( Figure 2C View Figure 2 ).
Unknown males.
