Diagnosis. Differs from all consubgeners by the reddish legs of males together with sexual dimorphism in body colour, by the bulging, enlarged promere and by the significantly tapering posterior opisthomere process (pp), which is much shorter than the solenomere ( Figs 13a–b, 13d ).

Promere (P) ( Figs 13a–c ) bulging, posteriorly with an enlarged lobe (l) almost covering the opisthomere from posterior direction. Opisthomere’s ( Figs 13a–b, 13d ) posterior process (pp) significantly tapering and apically very pointed, much shorter than the solenomere. Posterior solenomere process (psp) bent anteriorly.

This species shows true sexual dimorphism in body coloration: males are dark grey with slightly reddish legs; females have two bright longitudinal dorsal bands like M. projectum (Verhoeff 1897a) . Body length and height: males: 39.7–47.5mm, 2.8–3.4mm (34mm and 2.67mm according to Verhoeff 1897); females: 33mm, 3.5mm (Verhoeff 1897).

Remarks. Female vulva is unknown.
