In South Africa, the species is known from two provinces. Notable locations include Kei River Mouth, Umtamvuna Nature Reserve, Mtunzini and iSimangaliso Wetland Park.[3]
Habitat and ecology
Mystaria occidentalis is sampled from sweeping and beating vegetation in coastal beach forest, gallery forests, marshy areas near lakes and mountainous areas.[3] The species has been collected from Indian Ocean Coastal Belt and Savanna biomes at altitudes ranging from 6 to 601 m.[3]
Adults were collected over a year period from July to April, while juveniles were collected from March to June.[4]
