Langona spiralis sp. nov.

Fig. 29

Diagnosis. The shape of the body and colouration are typical for members of Langona . The epigyne unlike that in congeners and has two clearly separated depressions. Its internal structure is slightly similar to that in Langona pilosa Wesołowska, 2006 from Namibia, but the seminal ducts are clearly longer, spirally coiled in the initial half, whereas they only form a single loop in L. pilosa (compare Fig. 29C with fig. 48 in Wesołowska 2011b). Male unknown.

Etymology. The specific name is Latin and refers to the course of the seminal ducts, which are spirally coiled.

Type material. Holotype: ♀, MOZAMBIQUE: Inhambane: Bartholomew Diaz Point , 21°15.585’S, 35°06.851’E, mangroves, beating shrubs, 10.XII.2007, leg. R. Lyle & R. Fourie ( NCA 2020 /114).
