Argenna obesa
Plump Dictynid Spider
Argenna obesa is a small spider in the family Dictynidae, described by Emerton in 1911. It is known from prairie and grassland regions of central North America. The species is characterized by a notably plump, rounded abdomen that distinguishes it from related dictynid spiders. Records indicate it occurs in the Canadian prairies and north-central United States. Very little is known of its biology or ecological role.
