Maypacius is a genus of African nursery web spiders that was first described by Eugène Louis Simon in 1898.
Spiders in this genus are found in many parts of Africa, including Madagascar.
These spiders occur in the savanna and are found in vegetation.
The carapace is longer than wide and narrower in the eye region, with a sloping clypeus bearing projections. The anterior eye row is strongly procurved, with the anterior lateral eyes not on tubercles but located nearly below the anterior median eyes. The posterior eye row is strongly recurved.
The cheliceral furrow has two teeth that are equal in size. The abdomen is elongated and tapers towards the back. The legs have three claws and are relatively long.
The African species have not been revised, although Blandin described some species in 1975.
, the World Spider Catalog accepted nine species, found only in Africa:
