Estatus taxonómico:
Hahniidae was established by Bertkau (1878). However, Simon (1897)
only recognised it as a subfamily within the Agelenidae. Lehtinen
(1967) widened the limits of Hahniidae, recognised three
subfamilies, Hahniidae, Cryphoecinae and Cybaeolinae, and placed
them within the superfamily Amaurobioidea. However, Coddington &
Levi (1991) placed them in them in the Dictynoidea, but the
placement of the family remains doubtful.
Distribución: mundial.
Estilo de vida: Contruct
delicate sheet webs near the soil surface. Commonly found in
