Diagnosis. The male of this species is recognized by the shape of the embolus which is long and curved, with a very slender distal part supported by a complex MA which is clearly different from those in M. violaceus  and M. aurantioviolaceus  ; in these species the end of the embolus is supported by the short triangular prong at the tip of the MA. The latter two species also differ in their violet carapace.

Etymology. The specific name “ rwegura  ” is a noun in apposition taken from the type locality.
