Cybaeus morosus
Morose Woodland Spider
Cybaeus morosus is a small woodland spider in the family Cybaeidae, first described by Eugène Simon in 1886. It belongs to the 'marronoid' clade, a group of spiders united by molecular phylogenetics rather than obvious morphological similarities. The species is known from forest floor habitats in North America, where it constructs sheet webs or retreats under debris. Like other Cybaeidae, it is a ground-dwelling spider that plays a role in leaf litter decomposition and nutrient cycling.
