Introduction

Womersley (1956a) described Derrickia setosa from a protonymph, and later (Womersley 1956b) added a description of the deutonymph. He placed this genus in the family Podocinidae on the basis of its general appearance. However, Halliday (1990) showed that this species cannot belong in the Podocinidae but should probably be in some family of Trigynaspida. Its exact position cannot be determined until the adults are discovered. It is provisionally placed in the Paramegistidae, following Proctor et al. (2011).
