Austrochilidae
Austrochilidae is a small spider family with nine species in two genera. Austrochilus and Thaida are endemic to the Andean forest of central and southern Chile and adjacent Argentina.
Taxonomy
, two genera are placed in the family Austrochilidae: Austrochilus and Thaida, found in Chile and Argentina. The taxonomic placement of these genera has varied.In 1968, Lehtinen synonymized Austrochilus and Thaida under the latter name, placing the genus in a family he called "Thaididae". However, the family name "Thaididae" is preoccupied, being first used for a family of gastropods in 1887.
A single family was accepted by Forster et al. in 1987, under the name "Austrochilidae". Molecular phylogenetic studies agree in placing the two genera as basal members of the Araneomorphae, although the precise details and the family placement are not yet agreed.
