ABSTRACT
Abstract The female genitalia of Pero obtusaria Prout, 1928 (Lepidoptera: Geometridae) are described and illustrated for the first time and compared to congenerics. The antrum with the dorsal part sculptured with two sinuous longitudinal stripes enables the identification of this species.
ABSTRACT

Estudio filogenético de los géneros de Lithinini de Sudamérica Austral (Lepidoptera, Geometridae): una nueva clasificación. Se evalúa la taxonomía de la tribu Lithinini de Sudamérica Austral sobre la base de un análisis filogenético. Para el análisis se utilizó a Catophoenissa como grupo externo. Se usaron dos aproximaciones filogenéticas para evaluar las relaciones de parentesco: 1) criterio de parsimonia; e 2) inferencia bayesiana. El análisis de parsimonia se realizó a través del programa PAUP y el análisis bayesiano con cadenas de Markov y Monte Carlo a través del programa BayesPhylogenies. Los resultados generados a partir de la hipótesis filogenética permiten proponer una nueva taxonomía para los Lithinini de Sudamérica Austral. Los géneros validos son: Asestra Warren, Acauro Rindge, Calta Rindge, Euclidiodes Warren, Franciscoia Orfila y Schajovskoy, Incalvertia Bartlett-Calvert, Lacaria Orfila y Schajovskoy, Laneco Rindge, Maeandrogonaria Butler, Martindoelloia Orfila y Schajovskoy, Nucara Rindge, Odontothera Butler, Proteopharmacis Warren, Psilaspilates Butler, Rhinoligia Warren, Tanagridia Butler. Los principales cambios respecto de ordenamientos taxonómicos previos son: 1) Yalpa Rindge, es tratado como sinónimo junior de Odontothera. 2) El género Rhinoligia Warren es incorporado a los Lithinini; 3) Se reafirma que Siopla Rindge es sinónimo junior de Asestra, Yapoma Rindge y Duraglia Rindge son sinónimos de Euclidiodes Warren, mientras que Callemo Rindge y Guara Rindge son sinónimos de Tanagridia; 4) Los géneros Calta Rindge, Incalvertia Rindge, Odontothera Butler y Proteopharmacis Warren, sinonimizados por Pitkin, son redefinidos, revalidados e incorporados a la tribu Lithinini. Se describe una nueva especie para el género Franciscoia, F. ediliae Parra. Se incluye un catálogo con los géneros y especies de la tribu de la región, más las figuras de los adultos y genitalias de las principales especies.
In this work we evaluate the taxonomy of the Lithinini of Austral South America based on a phylogenetic analysis. In our analysis we used outgroup Catophoenissa. Two approaches were used to evaluate phylogenetic relationships: 1) parsimony criterion, and 2) Bayesian inference. Parsimony analysis was conducted in PAUP software, and Bayesian analysis with Markov chains Monte Carlo using the BayesPhylogenies software. Our results based on the phylogenetic hypothesis suggest a new taxonomic order for Austral American Lithinini. The valid genera are: Asestra Warren, Acauro Rindge, Calta Rindge, Euclidiodes Warren, Franciscoia Orfila and Schajovskoy, Incalvertia Bartlett-Calvert, Lacaria Orfila and Schajovskoy, Laneco Rindge, Maeandrogonaria Butler, Martindoelloia Orfila and Schajovskoy, Nucara Rindge, Odontothera Butler, Proteopharmacis Warren, Psilaspilates Butler, Rhinoligia Warren and Tanagridia Butler. The main changes with respect to the previous taxonomic order are: 1) Yalpa Rindge is the synonymous junior of Odontothera; 2) the genus Rhinoligia Warren is incorporated into the Lithinini; 3) while our analysis reaffirms that Siopla Rindge is junior synonym of Asestra, Yapoma Rindge and Duraglia Rindge are synonymous of Euclidiodes Warren, while Callemo Rindge and Guara Rindge are synonymous of Tanagridia; 4) the genus Calta Rindge, Incalvertia Rindge, Odontothera Butler and Proteopharmacis Warren, synonymized by Pitkin, are redefined, revalidated and incorporated into the Lithinini tribe. A new species for the genus Franciscoia, F. ediliae Parra is described. A catalogue of the genera and species of the tribe in the region, and the figures of adults and genitalia of some species are included.
ABSTRACT
A new species of Glena Hulst (Lepidoptera, Geometridae) from northern Chile. A new species of Glena Hulst (Lepidoptera, Geometridae) is described from two valleys of the coastal desert of northern Chile. Immature stages are associated with Trixis cacalioides (Kunth) Don. (Asteraceae). Holotype, male and female genitalia, and a sexual dimorphic feature are illustrated. This is the first record of a species of Glena from Chile.
Uma nova espécie de Glena Hulst (Lepidoptera, Geometridae) é descrita de dois vales do deserto litoral do norte do Chile. Os estágios imaturos estão associados com o arbusto Trixis cacalioides (Kunth) Don. (Asteraceae). O holótipo, a genitália do macho e da fêmea, e um caráter com dimorfismo sexual são ilustrados. Este é o primeiro registro de uma espécie de Glena para o Chile.
