The Prionocyphon warra- group

The group includes species whose genitalia (Figs 77–86) appear skeletonized, 'skinny' because the tegmen, parameres and penis are intimately connected into a functional unit consisting essentially of only hard sclerites. The tegmen resembles a flat bowl in P. monteithi but is reduced to a transverse band in P. warra . In both it supports slender parameres with an apical hook. The paramere bases are hinged with sclerites that are part of the long pala (missing in fig. 39 of Watts 2010b) with a high longitudinal keel. The strong lateral edges of the pala continue posteriorly as supports of the slender parameroids which are basally fused and end in a pair of spatulate sclerites. Between the tegmen and parameroids lies the slender, apically divided cone of the penis to which the unarmed endophallus is attached.

The above homologies are largely based on an undissected specimen of P. warra with erect genitalia, see below.
