[2] He based the original description of this species on a single female specimen found in the Maysan governorate (formerly Amara province) on the Tigris river in Iraq.

[4] Several specimens have been recorded in Israel, mostly from Mediterranean regions of the Galilee, at higher elevations with lower temperatures and more precipitation.

[5] This species has also been found in Gakal Cave in the Kohgiluyeh and Boyer-Ahmad province of Iran, indicating that M. evansi is a troglophile, living in subterranean habitats as well as at the surface.

[4][8] Specimens collected from the Basrah governorate include five males and six females found in 2022 on wet agricultural land, in the soil under palm trees, on the left bank of the Shatt Al-Arab river and in the Al-Hartha district.

In adults, the ventral side of the basal element of each ultimate leg has more than twelve scattered pores.

For example, like other species in this genus, M. evansi features a head that is evidently longer than wide and a body that tapers towards the posterior end.
