DISTRIBUTION AND BIOLOGY. Amorbia revolutana is known from Bolivia, Costa Rica, Cuba, Panama, and Venezuela ( Fig. 133). Records show flight activity in most months of the year.

IMMATURE STAGES ( Figs. 113–114). Egg patches are small and dark green. Larvae hatched in 13 days and developed on synthetic diet. Last instars are ca. 2.0 cm in length; the larval head is tan, with dark brown lateral bands; the prothoracic shield is tan with narrow lateral dark brown bands; the anal comb is absent. Development required ca. 9 weeks (JAP 99F67).

HOST PLANT RECORDS. Amorbia revolutana was reared from an unknown species of Rubiaceae and a Piperaceae ( Piper auritum ) (see Appendix III). The larvae are green with a tan to reddish head.

REMARKS. Amorbia revolutana was placed in synonymy of A. productana by Powell et al. (1995), but based on substantial differences in the male genitalia, the two are not conspecific. We did not find any difference between the male genitalia of A. revolutana and A. spilocryptis , and on this basis the synonymy of the two is proposed. Amorbia helioxantha Meyrick, 1917 was described from a female, and based on its genitalia and geographic distribution it could be conspecific with A. revolutana . However, until A. helioxantha males are found and studied, it is retained as a separate species.
