Note. This species is the most common Steatoda in Argentina, the 
type locality of T. ancoratum. Specimens of this species from Argen- 
tina determined by Mello-Leitao and by Biraben were named 
Lithyphantes ancoratum. The synonymy of L. vittatus Keyserling 
remains uncertain, however, as the type is a juvenile and no specimens 
of S. ancorata have been examined from Minas Gerais, the type 
locality. 
The palpi are variable in structure, (Figs. 44-47). Since the palpal 
sclerites are unusually complex, any slight change in position changes 
the appearance of the palpus. 
Natural History. Specimens have been found “near rockpile in 
weathered shale” and “under flat rock” in Bolivia. In Mendoza, 
Argentina it has been found in chaparral area. 
Distribution. Southern Mexico to southern Patagonia.
