Pisenor is a genus of mygalomorph spiders in the family Barychelidae. The genus is known from nine species endemic to Africa, distributed from Zimbabwe to the southern parts of Ethiopia.[3]
Pisenor spiders have body sizes ranging from 15–25 mm. Females are usually 'earth'-colored, varying from yellowish grey to reddish brown to greyish black, with the opisthosoma bearing pale spots or patches.[3]
The anterior lateral eyes are positioned close to the clypeal edge. The eyes are arranged in a group that is wider behind than in front, with the eye tubercle being distinct. A rastellum is absent, and the fovea is recurved. There are two pairs of spinnerets, and the metatarsal preening comb is absent. Males possess a tibial spur on leg I, while females have one row of teeth on the paired claws and males have two rows.[3]
Behavior and ecology
Pisenor species are ground-living burrow dwellers. Very little is known about their behavior, with the only published information being a note by Benoit (1966) who collected P. notius from a burrow with a trapdoor covered by bits of leaves.[3]
