COPESTYLUM COCKERELLI (CURRAN, 1927)

Puparium: Anterodorsal margin of mesothorax with enlarged setae (conspicuously longer than surrounding vestiture, not spicules. Dorsal vestiture of abdomen confined to medial areas of transverse folds. Crochets entirely black. Posterior breathing tube dark brown, short, less than half as wide as puparium, AP short, only about 0.4¥ as long as TR is wide, lightly punctate, tapering but bulging out horizontally ( Fig. 60 ). Pupal spiracles as long as AP and about 2.5¥ as wide apart as a pupal spiracle is long.

Material examined: 1 ♂, 3 ♀, four puparia PERU, Trujillo , Cerro Campana, 17.i.2005, ex decaying columnar Cactaceae , Espostoa melanostele (Vaupel) Bullock 1938 , collected by M. A. M. ( CIBIO) ; 1 ♀, one puparium same data as previous specimens ( NMS) .

Taxonomic notes: The puparium of C. cockerelli is distinguished from other Scutellatum group larvae considered here by the dorsal vestiture of the abdomen being confined to medial areas of the transverse folds, the entirely black crochets, and the short, horizontally bulging AP.
