Mashonarus guttatus Wesołowska & Cumming, 2002: 167, figs 1–19 (in part, paratype ♂ from Namibia).
Diagnosis
By the conformation of the copulatory organs (the shape of the embolus and the developed cymbial lateral projection), S. pseudoguttatus sp. nov. is most similar to S. brandbergensis comb. nov. and S. guttatus comb. nov. (cf. Figs 90–94 and 165–170), but can easily be distinguished from both related species by its having the longest, sword-shaped embolus, the largest open cymbial pocket and by the absence of a distal projection on the functional tegulum. The female of S. pseudoguttatus sp. nov. remains unknown.
Etymology
The specific epithet is a compound form of the Greek Ψϵυδο (‘pseudo’), ‘false’, and the Latin word ‘ guttatus ’, ‘speckled’; the name is a reflection of the fact that the holotype of this species was found in the original type series of S. guttatus comb. nov.
Material examined
Holotype
NAMIBIA: ♂, male paratype of Mashonarus guttatus Wesołowska & Cumming, 2002, Rundu-Kavango, ca 17°55′ S, 19°45′ E, Okavango Riv., May 1979, M.E. Baddeley leg. (MRAC 152.151).
Remarks
The series of paratypes of Mashonarus guttatus turned out to be heterogenous and contained one male that belonged to a different species, which is described herein as new.
