Alfenus
Alfenus is a genus of jumping spiders.
The two species were described by Eugène Simon in the early 1900s, based on a single male specimen each. However, the two species are so different that they probably do not belong to the same genus.
A. calamistratus has a characteristic hairy appearance.
The males are 7 to 9 millimeters long, with a dark brown carapace. The hairs on A. calamistratum are white or brownish-orange.Species
