Male. Unknown.

Remarks. The ZSI collection has one glass tube of this species, which is labeled as ‘holotype’ (3827/18), containing a female specimen in fairly good condition, with broken legs and intact genitalia. Judging from the original illustration of the epigynum of Makdiops shiva Crews & Harvey, 2011 , this species may be a junior synonym of M. agumbensis (compare Fig. 1C with Crews & Harvey 2011: fig. 89). However, confirmation requires the examination of the vulva of M. agumbensis for which we did not get dissection permission.
