Diagnosis. Females can be easily recognized by the shape of the spermathecae, which are distally widened to form a spherical apex ( Fig. 556 View FIGURES 545–556. 545–548 ). Males can be confused with those of M. capillipes sp. nov., but have a shorter apico-prolateral flange and a less pronounced apico-retrolateral lobe. This species is distinctly larger in size than that of M. capillipes sp. nov.

Etymology. The specific epithet ( clavigera = bearing a club) is a Latin adjective derived from Latin words (clava = club; gerere = to carry).

Coxae, trochanters, and femora orange; patellae yellowish; tibiae brown; metatarsi and tarsi yellowish brown. Opisthosoma sepia. Dorsal pattern: first and second pairs fused, forming reniform pale patches; third to fifth pairs represented by paired round spots.

Dorsal pattern: first and second pairs fused, forming paired longitudinal bands; third and fourth pairs represented by paired of pale round spots; fifth pair by transverse band.

Genitalia ( Figs 555–556 View FIGURES 545–556. 545–548 , 588–589 View FIGURES 587–589. 587 ).
