Genus Hexurella Gertsch & Platnick, 1979

Remarks.

We follow the generic diagnosis provided by Hedin and Bond in Hedin et al. (2019): adults males with a gently coiled embolus, posterior lateral spinnerets with four segments, and spermathecae composed of a single bursal opening branching into four or more elongate receptacles. As adults these spiders are also much smaller than other adult mygalomorphs from North America, except for the avicularioid Microhexura Crosby & Bishop, 1925. Hexurella differs from Microhexura in possessing abdominal tergites and six spinnerets.
