Brief SummaryRead full entry
The spider family Anapidae (ground orbweavers) includes 154 species (Platnick 2013). Two species of these very small spiders are reported from North America. One of these, Gertschanapis shantzi, is known only from humid forests of Oregon and California, where it spins small horizontal orb webs, with radii emerging from the flat plane, in spaces within the leaf litter, among fern fronds, in rotting wood near the ground, and in similar locations. This species is rarely encountered, but can be locally common. The other putative North American representative, Comaroma mendocino, is known from a single berlese leaf litter sample from California and Coddington (2005) has suggested that it does not belong in the Palearctic anapid genus Comaroma at all, but instead likely belongs in the family Theridiidae.
