Diagnosis. Anansi insidiator can be distinguished from other mimetids by its short cymbio-ectal process, flagellum in the conductor that is as long as the maximum cymbium width and epigynum piriform with its base wider.

Description. Male ( Figs. 14 View Fig. 14 and 15 View Fig. 15 ; GH98 4, GH1576). Habitus as in Figures 1 4 View Fig. 1 View Fig. 2 A – C.

Epiandrous fusules in two clusters; each cluster on a protuberance that carries ca. 5 fusules ( Fig. 15 View Fig. 15 A). Spinnerets as in Figures 15 View Fig. 15 I – K.

Female. ( Figs. 16 View Fig. 16 and 17 View Fig. 17 ; GH985-GH986). Habitus as in Figures 16 View Fig. 16 A – C.

PLS without cylindrical spigots ( Fig. 17 View Fig. 17 H).

Distribution. Cameroon, Central African Republic, Equatorial Guinea and Gabon.

Remarks. Although we were unable to examine Thorell’s type specimen of Mimetus insidiator , his description and additional descriptions and drawings in the works of Simon (1903) and Lessert (1930), and the thesis of Harms (2007), allow the species identification.
