Abstract

A sphinx moth survey was carried out in the state of Maranhão with morphological characterization of the species belonging to genus Isognathus Felder & Felder, 1862, which were found in this state. The studied material was acquired from nacional entomological collections as well as through captures by using a white cloth and a 250-watt mixed mercury tungstan vapor lightbuib. Fifty-seven (57) species were recorded for the first time in the state of Maranhão, ofthese 14 are new recordsfor the Brazilian northeast. The four Isognathusspecies listed (/. allamandae, I. caricae caricae, 1. menechus and /. scyron)for the state were characterized as to color pattern and,for the first time, as to morphology of the genitalia. Dictomic keys based on color pattern and genitália characteristics are presented.
