Metaltella
Metaltella is a genus of South American spiders in the family Desidae (formerly Amphinectidae), first described by Cândido Firmino de Mello-Leitão in 1931. The genus contains six species distributed across Argentina, Brazil, Chile, Peru, and Uruguay. One species, Metaltella simoni, has been introduced to North America and is now established in the southeastern United States and Canada. Members of this genus are hacklemesh weavers that construct webs with retreats. The genus is notable for its intertidal ecology in its native range and its successful establishment as an introduced species in North America.
Metaltella simoni
South American Toothed Hacklemesh Weaver
Metaltella simoni is a small hacklemesh weaver spider native to South America (Argentina, Uruguay, and Brazil), introduced to North America through human commerce. First recorded in Louisiana in 1944, it has become established in the southeastern United States and coastal southern California, with subsequent records in Canada. The species builds sheet webs with a retreat and exhibits distinctive behaviors including leaving the retreat when threatened, which increases vulnerability to predation.
