Description: Female. Length of idiosoma 490 µm, width (in the middle of idiosoma) 400 µm (n = 1). Shape oval, posterior margin rounded.

Dorsal side ( Fig. 14 ): Dorsal shield with many blade-like setae. Dorsal and marginal shields without ornamentation, with only some alveolar ornamentation on caudal part of dorsal shield. Marginal setae smooth, short and filiform.

Ventral side ( Fig. 15 ): Sternal shield with small alveolar ornamentation, sternal setae short, smooth and filiform. Ventral shield with alveolar ornamentation. Ventral setae longer than sternal setae, smooth and filiform.

Genital shield large, oval and with alveolar ornamentation. Genital shield between coxae 2 and 4. Genital shield with a large perigenital region.

Gnathosoma: Not clearly visible, covered by coxae 1.

Material examined: holotype: female, Angola, Dundo, foret R. Cambuacala 25 March 1960, leg. MACHADO .

Etymology: This species is named after the country where it was found.

Remark: This species belongs to the paradoxa -group. The new species is similar to the following two species: Oplitis cubana WIŚNIEWSKI & HIRSCHMANN, 1991 and Oplitis oblita HIRSCHMANN, 1991 . The main differences are the following: the ventral setae of the new species are filiform, but the two known species have blade-like ventral setae.
