Figs 5– 6 , 7E

Diagnosis

Males resemble those of M. luiscarlosi sp. nov. in having a similar copulatory bulb shape but can be distinguished by the embolus length less than 3 × the maximum width of the tegulum, with truncated tip ( Figs 5C–D , 7E ) (larger, with pointed tip in M. luiscarlosi , Figs 4E–F , 7D ). Females unknown.

Etymology

The specific epithet refers to the type locality ‘Santa Rosa de Cabal’; noun in apposition.
