Acanthogonatus confusus is a mygalomorph spider of Argentina and Chile, its name referring to the confusion between this species and A. subcalpeianus.[1] Males are recognized by their long palpi, together with the absence of a tibial apophysis; females are recognized by the spermathecae (similar to A. fuegianus, A. centralis and A. parana, which have - unlike A. Confusus - no inferior tarsal claws on tarsus IV).

Description

Distribution

Forests in southern Chile (Regions VIII-X) and adjacent Neuquen Province (Argentina).

Taxonomy and behaviour

Goloboff (1995) states there may be more than one species included in his description study. A lack of specimens in his initial observations made it difficult to statistically describe Argentinian specimens, which had smaller and more convoluted spermathecal ducts, and thus different species were not distinguished.

The specimens from Pinares (Concepción, Chile) from that same article, have a shorter outer spermathecal lobe than other specimens, probably being juveniles.

Adults were found under stones and logs, where they construct a silk tube and a shallow burrow. At Contulmo and Pata de Gallina juveniles were collected in moss or loose soil.
