Deposited in CDRS, CNC, MHNG.   Diagnosis:Although the males of this dark brown species with darker brown markings ( Fig. 49) are easily separated from other species by virtue of their thickened antennae at base and enlarged anal sector of the hindwing, females ( Fig. 50) will be best separated with the key presented above under  Herpetogramma phaeopteralis(Guenée). The wingspan of the available males is 20-22 mm, that of the females 18-19 mm.   Biology:Known as the Eggplantwebworm ( Heppner, 2003) the larva has been reared on several species of Solanaceae, including many tomatospecies (  Solanumspp.), potato(  Solanum tuberosumL.), and tobacco(  Nicotiana tabacumL.), but also on other plants in the Acanthaceae, Amaranthaceae, Cucurbitaceae, Myrtaceae, Phytolaccaceae, Piperaceae, and Rosaceae ( Robinson et al., 2014). In the Galápagosmoths were collected between sea level and 1000 min elevation, mostly in uninhabited areas or islands, in January until May.   Distribution:Based on BMNH specimens this widespread WesternHemisphere native described from the USAis also found in Jamaica,  Mexico, Venezuela, Colombia, Brazil, Peru, and Argentina. Ferguson et al. (1991)also mention it from Bermudaand as a migrant in the eastern USAas far north as Massachusetts(see also Patterson et al., 2015). In the Galápagosit has been found so far only on the four islands listed above.   Remarks:External characters of the male holotypein the BMNH were found to match Galápagosspecimens. The holotypehas no abdomen, but the wing pattern and the enlarged anal angle of the hindwing are deemed sufficient to insure proper identification.
