Menemerus spiders are found throughout Africa and Asia, and have been identified as far as Latin America. Menemerus mirabilis is endemic to Ethiopia. The species thrives in areas of human habitation. The male holotype was found in 1988 in a house in Addis Ababa at an altitude of 2,400 m (7,900 ft) above sea level. Other examples, both male and female, have been found nearby and in a hotel.
