Diagnosis. Females of this species are easily distinguished from the remaining species of the genus by the fact that this is the only species in which the initial part of the copulatory ducts is directed toward the inner side of the epigynum ( Fig. 23 ).

Distribution. Known from the states of Pará, Mato Grosso and Mato Grosso do Sul, Brazil.

Note. Since all the remaining species of this genus have the initial part of the copulatory ducts running to the lateral sides of the epigynum, it is possible that this species belongs to another lineage, maybe an undescribed genus.
