COPESTYLUM LATUM (WIEDEMANN, 1830)

Larva and puparium: Anterior fold with a narrow band of spicules. Metathorax with two linear groups of distinct spicules on the anteroventral margin and some spicules on the lateral margins. Dorsal vestiture comprising shorter setae in the middle of transverse bands and with anterodorsal groups of large, broad setae on the mesothorax and metathorax. Abdominal segments 4–6 with second row of crochets inconspicuous and not as developed as on abdominal segments 1–3. Posterior breathing tube red-brown at base, dark brown at apex, below TR tube nodulate, above shiny. AP about a third as high to spiky rim as wide at TR. Pupal spiracles about 2¥ as far apart as a pupal spiracle is long and curved in upper third. Openings coating upper half of one side, those at the apex without a lateral projection.

Taxonomic notes: Most similar to C. macrocephalum from which it differs in the broader, shorter posterior breathing tube which above the TR to the spiky rim is only about a third as long as TR is wide.
