Microctenus curvipes Keyserling, 1881: 579 , pl. 16, fig. 24 (male holotype from Panama, deposited in C.L. Koch personal collection, not examined, probably lost).

Ctenus curvipes: Simon 1897:107 , fig. 100; F.O. Pickard-Cambridge 1897: 86, pl. 3, figs 6a, 7e; Polotow & Brescovit 2014: 355, fig. 12C; World Spider Catalog 2018.

Ctenus incolans F.O. Pickard-Cambridge, 1900: 111 , pl. 7, figs 35–36 (female holotype from Guatemala, deposited in BMNH 1901.3.3.142–143, examined). World Spider Catalog 2018. New synonymy.

Diagnosis. Males of Kiekie curvipes ( Fig. 6A ) can be distinguished from the remaining species of the genus by the cylindrical and S-shaped RTA, positioned roughly in the middle of palpal tibia; the bimarginated, cup-shaped median apophysis and the round projection at the embolus base. Females can be distinguished by the absence of a hyaline area in the lateral field, close to the copulatory opening, which is present in the remaining species of the genus ( Fig. 6B ).

Note. The species was identified by the original description and drawings.
