COPESTYLUM TAMAULIPANUM (TOWNSEND, 1898)

Larva and puparium: Anterior fold without extra large spicules. Anterior spiracles with three openings. Abdominal vestiture of short, upright setae. Anal lobe without spicules. Posterior breathing tube orange, tapering. AP smooth, shiny and as long as TR is wide. Pupal spiracles orange, matt, and with three encircling rings of openings in upper third. Pupal spiracles as wide apart as a pupal spiracle is long.

Taxonomic notes: Copestylum tamaulipanum is very similar to C. alberlena and C. multipunctatum in having a tapering posterior breathing tube and light orange pupal spiracles. It differs from both these species in the AP that is as long as the TR is wide. In the latter two species the AP is shorter than the TR is wide.
