COPESTYLUM HAMBLETONI ( FLUKE, 1951)

Puparium: Anterodorsal margin of mesothorax with enlarged setae, not spicules. Dorsal vestiture of abdomen spread across folds and not strongly confined to medial transverse bands although shorter in front and behind. Crochets translucent with dark red tips. Posterior breathing tube dark brown, long almost as long as puparium is wide with AP about 0.8¥ as long as TR is wide, coriaceous and faintly punctate and tapering sharply to about 0.5¥ of width of TR ( Fig. 61 ). Pupal spiracles short, about 0.7¥ as long as AP and about 1.4¥ as wide apart as a pupal spiracle is long ( Figs 56, 57 ).

Material examined: 2 ♂, 3 ♀, five puparia ( CIBIO), 1 ♀ and puparium ( NMS), PERU, Trujillo, Cerro Campana, 17.i.2005, ex decaying columnar Cactaceae , E. melanostele . Known only from Cerro Campana, Trujillo, Peru, collected by M. A. M. ( CIBIO).

Taxonomic notes: The puparium of C. hambletoni is distinguished from other Scutellatum group species considered here by the long posterior breathing tube with its sharply tapering AP and the crochets on the prolegs, which have dark red tips.
