Acanthogonatus huaquen is a mygalomorph spider of Chile, its name referring to its type locality: Huaquén, Chile.[1] Males are recognized from other two-clawed Acanthogonatus by the bulb with a lateral keel delimiting a concave area; females by the spermathecae with an almost conical basal mound and its duct arising from its tip (similar spermathecae occur in A. franki).

Description

Distribution

With A. campanae and A. pissii, A. huaquen is one of the most common nemesiids in central Chile (Regions IV and V). It has not been found in Region Metropolitana, where A. quilocura seems to replace it.

Taxonomy and Behaviour

Goloboff (1995) states there may be more than one species included in his description study. Specimens from Quereo and Caleta Oscura were observed to have longer, spiraled spermathecal ducts; they may represent a different species. This species builds open burrows, lined with a dense layer of silk. The silk lining elongates to the burrow's entrance forming a sort of collar; the burrows are up to 2 centimetres (0.79 in) in diameter, and between 20 and 25 centimetres (7.9 and 9.8 in) deep. In forest ecosystems, the spider prefers more forested parts (not necessarily too moist); they are very common in the open grassland.
