Adiciones a la fauna de geométridos (Lepidoptera: Geometridae) de Chile

Abstract

-Three species of geometrid moths are reported from the extreme North of Chile. All three are new for the Chilean fauna: Scopula umbilicata (Fabricius, 1794) (Sterrhinae), Cataspilates grisescens Warren, 1897, and Pero obtusaria Prout, 1928 (Ennominae).

An updated catalogue of the Geometridae (Lepidoptera: Geometroidea) from Chile. Part I: Archiearinae, Geometrinae and Sterrhinae

“…12, 33, 54, 77;Scoble, 1999: 867;Vargas & Hausmann, 2008: 167. (Vargas & Hausmann 2008); March to October was reported for its most northern distribution range (Covell 1970). Genitalia: Covell, 1970: fi gs 12, 33, 54.…”

A new species and a new record of Pero Herrich-Schäffer, 1855 (Lepidoptera, Geometridae) in the Andes of southern Peru

“…The genus Pero is well diversified in the Andes but only one species has been recently reported from Andean environments of southwestern Peru (Cerdeña et al 2019). However, a few discoveries dealing with this genus and other representatives of Geometridae in similar arid environments suggest that this poor representation is due more to a lack of data from low collection effort than to low diversity in this geographic area (Vargas and Hausmann 2008;Vargas et al 2020).…”

Rhodometra sacraria (Linnaeus), a cosmopolitan sterrhine confirmed from Chile (Lepidoptera, Geometridae)

“…In addition, neither R. sacraria nor R. angasmarcata (about whose biology there is nothing known, but which may also be expected to demonstrate migratory tendencies) have been documented from those areas of northern Chile which may more likely be points of entry across valleys for those Neotropical species whose southern distributional limits incorporate northern Chile, for example, S. umbilicata (Covell, 1970) and Pero obtusaria Prout, 1928 (Ennominae) (Poole 1987). Both of these geometrids were very recently documented from Chile (Vargas & Hausmann 2008).…”

“…Data on these specimens is as follows: In addition, amongst the Sterrhinae, R. sacraria is the second sterrhine taxon which has been taken in the centre-south of the country, and the only sterrhine species as far south as Biobío. For example, S. umbilicata was documented from Arica (extreme north just south of Peru) (Vargas & Hausmann 2008), whilst, the three species in the genus Cyclophora Hübner, 1822, C. nanaria, C. semirosea and C. umbrata, are known either from the Azapa Valley (Arica), or from the Tamarugal Pampa (Iquique) (C. nanaria), or from Valparaíso (C. semirosea, C. umbrata) (Vargas et al 2001). On the other hand, the subfamily Larentiinae is well represented in the meridional zones of Chile.…”
