The Gnaphosoidea are a superfamily of araneomorph, mostly eight-eyed spiders, with seven families:
The Prodidomidae, Lamponidae and Gnaphosidae are considered "higher gnaphosoids", sharing anterior lateral spinnerets consisting of only a single article; the lower gnaphosoids (Ammoxenidae, Cithaeronidae, Gallieniellidae and Trochanteriidae) retain a separate, complete distal article that is represented by an entire, subdistal ring of sclerotized cuticle[1]. Taxonomic rank ( rank, category, taxonomic category is an abstract term used in the Scientific classification, or Taxonomy, of organisms The Araneomorphae are a Suborder of Spiders They are distinguished by having Chelicerae (fangs that point diagonally forward and cross in a pinching action The Ammoxenidae are a small Spider family with 18 species in four genera The Cithaeronidae are a small spider family with only six species in two genera The Gallieniellidae are a Spider family with 48 species in ten genera The ground spiders (family Gnaphosidae) include nearly 2000 described Species in over 100 genera worldwide The Lamponidae are a Spider family with about 200 described species in 23 genera The Prodidomidae are a Spider family with about 300 species in 31 genera The Trochanteriidae are a Spider family with 149 species in 18 genera
