This family-group name of Wiltshire, though a nomen nudum (Kühne & Speidel, 2004), could be used for the concept of the Polydesmini of Guenée which is preoccupied in Myriopoda by Polydesmidae of Leach (Kühne & Speidel, 2004; Speidel & Naumann, 2005). The two included genera share a number of unusual or unique features.

The male genitalia of the externally rather dissimilar genera share the presence of a bundle or bundles of long, robust setae just basal to a distinct narrowing of the valve. The females of both have small spicules or spines within the bursa, particularly in the basal part. The larvae share full development of abdominal prolegs and possession of a complex internal armature of teeth on the mandible, the first probably a reversal of the characteristic reduction seen in core catocalines, and the second a unique feature, both probably adaptations for bark-feeding on Leguminosae.

Other general features such as the form of the juxta, position of the ostium and observations in
Polydesma Boisduval of a pupal bloom are consistent with inclusion amongst the core catocalines; Fibiger (2003) placed both genera in his subtribe Ophiusina, and associated Pandesma with the Pericymini in his Zethes-Pericyma genus group. Swinhoe (1900) included both genera in his Polydesminae, along with several other genera including Leguminosae feeders such as Erygia Guenée (p. 130) and Ericeia Walker (p. 116).
