Abstract

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.

Highlights

Geometridae is the second largest family within Lepidoptera, with approximately 23000 species worldwide (Scoble 1999; Scoble and Hausmann 2007; Van Nieukerken et al 2011)
Larentiinae is the second largest subfamily within Geometridae (Gaston et al 1995; Scoble et al 1995), its members occur in a wide variety of habitats, and is abundant at great altitude in the tropics and in temperate forests (Holloway 1997), like those in south-central Chile (Hausmann and Parra 2009; Zamora-Manzur et al 2011)
The Barcode Index Number (BIN) of each species is reported which was obtained from the BOLDSystems v4 database (Ratnasingham and Hebert 2007)

Summary

Introduction

Geometridae is the second largest family within Lepidoptera, with approximately 23000 species worldwide (Scoble 1999; Scoble and Hausmann 2007; Van Nieukerken et al 2011). Larentiinae is the second largest subfamily within Geometridae (Gaston et al 1995; Scoble et al 1995), its members occur in a wide variety of habitats, and is abundant at great altitude in the tropics and in temperate forests (Holloway 1997), like those in south-central Chile (Hausmann and Parra 2009; Zamora-Manzur et al 2011). Despite their high species-richness in Chile (i.e., around half of known Chilean geometrids are larentiines), there are relatively few studies related to these moths as compared to the Ennominae. Most research efforts focused on the revision of the genus Eupithecia Curtis (Vojnits 1985, 1992, 1994; Rindge 1987, 1991) and the tribe Trichopterygini (Parra 1991, 1996; Parra and Santos-Salas 1991, 1992; Parra et al 2009, 2017)
