[1] Females are most similar to those of A. parana, are distinguished by the widened fundus of the spermathecae.

Males, on the other hand, are recognized by the smooth, keelless bulb, in combination with a well-developed tibial apophysis.

The species is easily found under stones, where they construct a dense silk tube (which usually also implies a short burrow).

Adult males are capable of constructing tunnel-webs, but they are quite different from those of juveniles and females, lacking the short burrow.

Females remain active during copulation by making body jerks and struggling.
