DOI: 10.1525/cond.2013.110198 INTRODUCTION The genus Automolus is composed of medium-sized foliage- gleaners (Furnariidae: Philydorini) inhabiting tropical and subtropical humid forests in Central and South America. Because of their lack of distinguishing morphological charac- teristics, in the past, assessments of affinities and taxonomic limits in Automolus have been speculative (e.g., Vaurie 1980). However, a combination of relatively large size, plain plum- age, straight bill, and slightly elongated crown feathers sets most species of Automolus apart from most other foliage- gleaners (Cory and Hellmayr 1925, Parker 1979, Vaurie 1980, Ridgely and Tudor 1994). All Automolus species inhabit the forest undergrowth, where they glean invertebrates from the vegetation, in particular from dead leaves, debris, and, to a lesser degree, epiphytes (Remsen and Parker 1984, Rosenberg 1997, Remsen 2003). Also, like most other foliage-gleaners, Automolus species nest in burrows dug in earthen banks (Vaurie 1980, Zyskowski and Prum 1999, Remsen 2003). Recently acquired field data on habitat, behavior, and vocalizations have provided additional evidence for relation- ships among the foliage-gleaners (Kratter and Parker 1997, Robbins and Zimmer 2005, Zimmer et al. 2008). Three spe- cies formerly placed in Automolus have been transferred to other genera on the basis of vocalizations, nest placement, habitat, feeding behavior, and morphology (Remsen et al. 2012).

We investigate phylogenetic relationships among the foliage-gleaners of the genera Automolus, Hy- loctistes, Hylocryptus, and Clibanornis (Furnariidae) by means of DNA sequences of mitochondrial and nuclear genes. The genus Automolus is not monophyletic because A. rubiginosus and A. rufipectus are more closely related to Hylocryptus and Clibanornis and because Hyloctistes is nested within the main Automolus clade. Hylocryptus erythrocephalus and H. rectirostris are not sister species; the former is part of the A. rubiginosus complex, whereas the latter is sister to Clibanornis dendrocolaptoides. Two species, A. infuscatus and A. rubiginosus, are not mono- phyletic, indicating the need for further taxonomic revision. On the basis of our phylogenetic analyses and of quan- titative assessments of phenotypic variation, we propose a new classification for Automolus and allies, including the description of a new subgenus. Key words: classification, Cryptomolus, foliage-gleaners, neotropical birds, Philydorini, phylogeny. Filogenia y Clasificación de Automolus y Géneros Relacionados (Aves: Furnariidae) Resumen. Investigamos las relaciones filogenéticas de los géneros Automolus, Hyloctistes, Hylocryptus y Clibanornis (Furnariidae) mediante secuencias de ADN de genes mitocondriales y nucleares. El género Automo- lus no es monofilético porque A. rubiginosus y A. rufipectus están más relacionados con Hylocryptus y Clibanor- nis y porque Hyloctistes está incluido dentro del clado principal de Automolus. Hylocryptus erythrocephalus y H. rectirostris no son especies hermanas; la primera es parte del complejo de A. rubiginosus mientras que la segunda es hermana de Clibanornis dendrocolaptoides. Dos especies, A. infuscatus y A. rubiginosus, no son monofiléticas, lo que sugiere la necesidad de una revisión de los límites de las especies en el grupo. A la luz de estos resultados, complementados con un análisis de heterogeneidad morfométrica, proponemos una nueva clasificación para Auto- molus y géneros relacionados, incluyendo la descripción de un subgénero nuevo.
