orbitelariæ

Century Dictionary and Cyclopedia

1. A superfamliy of spiders, comprising all those forms which spin orbshaped webs. At present the families Epeiridæ, Uloboridæ, and Tetragnathidæ are the only ones included. It is a natural group, the structural characters showing great uniformity. A few genera, however, are included here on account of structural features, which do not spin orb-webs. See Pachygnatha.
