Dos nuevas especies de Iridopsis Warren (Lepidoptera, Geometridae) del norte de Chile

First host plant records for Iridopsis hausmanni Vargas (Lepidoptera, Geometridae) in the coastal valleys of northern Chile

“…However, the biology of the Neotropical species is little known, with only a few host plant records published (Passoa 1983;Vargas 2007;Marconato et al 2008;Bodner et al 2010;Robinson et al 2010). In contrast, host plant relationships are better documented for the Nearctic species, many of which are polyphagous (Robinson et al 2010).…”

“…The genus has been recently recorded from Chile, where it is represented by two described species, both from the Atacama Desert (Vargas 2007). Iridopsis parrai Vargas, 2007 is restricted to the Pampa del Tamarugal, and its larvae are folivorous on the native tree Prosopis tamarugo Phil.…”

“…Iridopsis parrai Vargas, 2007 is restricted to the Pampa del Tamarugal, and its larvae are folivorous on the native tree Prosopis tamarugo Phil. (Fabaceae).…”

“…Its immature stages have been recently described and illustrated (Vargas & Parra 2013). Iridopsis hausmanni Vargas, 2007 has been reported only from the Azapa valley, Arica Province, and nothing has been published about its host plant relationships.…”

“…The two Chilean representatives of Iridopsis are apparently closely related, based on male genital morphology (Vargas 2007), thus it was supposed that larvae of I. hausmanni could be associated with some host plant in the family Fabaceae. native Fabaceae trees of this locality were offered to first instar larvae: Acacia macracantha, Geoffroea decorticans, Leucaena leucocephala and Prosopis alba.…”
