Diagnosis:
Males:
This species is characterized by the prominent trilobate post-ocular groove and hump, as well as the short palpal prolateral apophysis, the distally oriented palpal prolateral spike, the protegulum palpillae and the embolic division [see description in
Tanasevitch (2020b)
]. These features, shared with
M. tholusa
, suggest a close relationship between them, but they can be distinguished by the position of the palpal tibia prolateral apophysis, which is more distally situated in
M. tholusa
than in this species.
