Introduction

The genus Karriella comprises two species that occur in south-west Western Australia. This genus is part of the subfamily Borralinae Gray & Smith, 2008. Members of most genera in the subfamily, including Karriella, have a longitudinally striped carapace which in males is usually distinctly highest at the fovea. Karriella females have an unusual characteristic in the form of a pair of sclerotised “knobs” on the epigynum, one or both of which are usually missing in mated specimens. Most specimens of both sexes have a putative stridulatory mechanism between the palpal femur and lateral chelicerae. They are forest-dwelling spiders that make a fine cribellate sheet web. The catching web is guyed out from a funnel-like retreat, typically in a rotten log, under bark or moss or into a steep bank. The spiders run on the underside of the sheet.
