Type material examined.

Holotype ♀, Tanzania, Moschi [=Moshi], 1953, Hartmann leg., Coll. C.F. Roewer (SMF 9910418). Paratype 1 ♀, Tanzania, Aruscha [=Arusha], Hartmann leg., Coll. C.F. Roewer, 1953 (SMF 9907949).

Diagnosis.

M. moschiensis comb. nov. and M. kiboschensis both have horizontally ovoid anterior lobes of the spermatheca and deep concave epigyne anterior delimiting edges (Figs 5B, 7B). They can be distinguished by the position of the copulatory ducts which are of central origin but protruding anteriorly in M. moschiensis comb. nov. (Fig. 7B) compared to posterior origin and projected centrally in M. kiboschensis (Fig. 5B). The shape of the median lobe is small and round in M. kiboschensis (Fig. 5B) compared to larger and ovoid in M. moschiensis comb. nov (Fig. 7B).
