The Geometridae are the second most diverse family of Lepidoptera. Seven subfamilies of geometrid moths have been recognized worldwide, and five of those have been recorded in Chile. The highest species richness of Chilean Geometrids is concentrated in Ennominae and Larentiinae, subfamilies that will be treated in subsequent volumes of this catalogue. The earlier catalogue of the Chilean geometrid moths was published by Angulo & Casanueva (1981), who listed species with no more records that type locality and some flight periods. Since then, much of the taxonomic knowledge has changed, resulting in new combinations and descriptions of numerous new species, as well as establishing new species records for Chile. For each species, we include BIN number (if available), synonymy, biological data, host, references, known geographical distribution, flight period and reference photographs of species. In order to obtain both old and new data, we used specimens from different national and international scientific collections. The result was a review of 13 geometrid moths, which represent the three less known subfamilies of this group in Chile: Archiearinae, Geometrinae and Sterrhinae.

Four new species belonging to the genera Hoplosauris Butler, Butleriana Parra, Warrenaria Parra, and Fueguina Parra from south-central Chile are described. The species are H.morenoi Ramos-González & Parra, sp. n., B.phoenix Ramos-González & Parra, sp. n., W.onca Ramos-González & Parra, sp. n., and F.araucana Ramos-González & Parra, sp. n. The genus Aloba Warren is reassigned to tribe Trichopterygini and A.carolinae Ramos-González & Parra, sp. n. is described. Comparative diagnosis for all new species are provided, and illustrations of genitalia and the wing venation of the males for all new described species are given.
