Type material examined.

Holotype ♀, Mozambique, Tete, 1953, Coll. C.F. Roewer (SMF 9909999).

Diagnosis.

M. mossambica comb. nov. strongly resembles M. lawrencei by sharing similar characters such as the shapes of the anterior lobe of the spermatheca and epigyne anterior delimiting edge and position of copulatory ducts (Figs 6B, 8B). The two species can be distinguished by the shape of the epigynal teeth which are thick in M. lawerencei (Fig. 6A) compared to slender in M. mossambica comb. nov. (Fig. 8A). The copulatory duct is also large and close together in M. mossambica comb. nov. (Fig. 8B) compared to smaller and further apart in M. lawrencei (Fig. 6B). These two species can also be separated by the length to width size ratio of the epigyne which is 0.6:0.6 in M. lawrencei compared to 0.7:0.5 in M. mossambica comb. nov.
