Diagnosis

This species is closely related to Ansienulina mirabilis Wesołowska, 2015 . It can be recognized by its uniformly olive abdomen whereas A. mirabilis has a distinct light serrated streak. The tibial apophysis of the pedipalp is clearly smaller, spike-like and the cymbium is ‘typically’ spoon-shaped, whereas in A. mirabilis it is strongly bent towards its dorsal surface (compare Fig. 4F, H with Wesołowska 2015: figs 8, 10).

Etymology

This species is dedicated to Prof. M. Lamotte, one of the founders of Lamto research station.

Material examined

Holotype IVORY COAST • ♂; Cavally Forest ; 20 Nov. 1975; “sur les hautes branches, arbres abattus”; MNHN.
