Introduction

This family was recognised by Richards' (1968) revision but is treated here as a family following Betsch (1980), who raised Richards' seven subfamilies to family status. So far 4 genera and 33 species are recognised from Australia. A further two genera, Stenognathellus Stach, 1956 (Greenslade & Thompson 1981; Greenslade 1982, 1985; Greenslade & Greenslade 1989) and Pseudokatianna Salmon, 1944 (Greenslade & Greenslade 1977) are without described species in Australia. The Katiannidae is a subfamily of predominantly southern distribution which is well developed in cool humid parts of Australia and contains some undescribed genera.

Diagnosis

Trochanteral organ present on leg III.
