Coneweb spiders (Diguetidae) are six-eyed haplogyne spiders that live in tangled space webs, fashioning a cone-like central retreat where they hide and lay eggs. It is a small family, containing only two genera split between a range in the Southwestern United States and Mexico and a range in South America.[1] Members of the genus Diguetia usually build their webs in shrubs or between cactus pads. They have the same eye arrangement as the venomous recluse spiders (family Sicariidae).
Taxonomy
[edit]The group was first created by F. O. Pickard-Cambridge in 1899 as the subfamily Diguetiinae of the family Scytodidae.[1][2] It was raised to the rank of family by Willis J. Gertsch using the spelling "Diguetidae".[3] Pickard-Cambridge's use of double "i" is correct according to Article 29.3 of the International Code of Zoological Nomenclature,[4] since the name is based on the genus Diguetia. In 2004, Jörg Wonderlich suggested reducing it again to a subfamily, this time of Plectreuridae.[5] However, it is still sometimes considered a subfamily of the Plectreuridae.[1]
