Diagnosis. Females can be easily recognized by the shape of the spermathecae, which are distally widened to form a spherical apex (Fig. 556). 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).

Palp (Fig. 587). RTA digitiform, gradually tapered towards terminally bluntly pointed apex. TA with sharply pointed apico-prolateral flange; apical process represented by triangular tooth; meso-prolateral fold triangular, broad; basal ridge running obliquely.
