COPESTYLUM FRAUDULENTUM (WILLISTON, 1891)

Larva and puparium (prothoracic plate and pupal spiracles missing): Dorsal abdominal vestiture coating the surface but shorter on either side of the transverse folds. Ventral abdominal vestiture dense and of varying length across folds: anterior sides of folds with longer setae than posterior sides. Posterior breathing tube red-brown, surface corrugated and lightly punctured, about half width of puparium. TR deep and distinct. AP bulging, not tapering, about 0.77¥ as long as TR is wide and with spiracular openings of simple s-shaped curves.

Taxonomic notes: The larva and puparium are readily distinguished from those of other species in this group by the clearly discernable TR on the posterior breathing tube and the dorsal abdominal vestiture which completely coats the integument.

Material examined: 1 ♂, one puparium USA Arizona, Phoenix 12.ii.1939 collector unknown ex cactus ( SI) .

Previous records: Mann (1969) ex Opuntia .
