Similar to male, except T7 and terminalia shining black (Fig. 31A–C); T7 black; S6 and S7 greyish brown pruinose with sparse, thin and long yellowish setae; T8 black setose; T9+10 and cercus reddish yellow to reddish brown setose; S8 with dense golden reddish brown setae; keel of genital opening and hypoproct with short and stout dark reddish macrosetae (Fig. 31A–F); spermathecal capsules rounded (Fig. 31G); spermathecal pump about 2 times smaller than the length of spermathecal duct, slightly turgid (Fig. 31G); spermathecal ducts ending separately at genital fork (Fig. 31G–H); apodeme of genital fork connected laterally with lateral sclerites (Fig. 31G–I); lateral sclerites connected with T9+10; apodeme of genital fork with a slight lateral expansion at mid-length (Fig. 31G–H) and without a mid-dorsal ridge (Fig. 31I).

Variation. Ocellar tubercle with 3 pairs of ocellar setae with the anterior pair stouter; mystax composed of almost only black macrosetae, with the yellow macrosetae restricted to the oral border; T6 and 7 S6 and 7 with thin and long golden setae forming a tuft.

Taxonomic discussion. This species can be differentiated from other Catostola species mainly by the yellow mystacal macrosetae (Fig. 27C–D), fore and mid femora black anterodorsally and yellow posterodorsally with hind femur entirely black (Fig. 27A); absence of femoral swelling on hind femur ventrally; epandrium with apical projection located ventrally (Figs 28E, 29E); cercus with short and stout macrosetae ventrally apically and subepandrial sclerite with a ventral keel and ventral rounded projections (Fig. 30H–I).

Distribution (Fig. 45). Ecuador (new record) (Sucumbíos, Napo, Morona Santiago and Zamora-Chinchipe), Brazil (Amazonas), Peru (Cuzco, Loreto, Madre de Dios) and Bolivia (La Paz, Sara, Ichilo, Chuquisaca).
