ABSTRACT ∙ The life histories of most Epinecrophylla antwrens are poorly known. I describe the first nest and egg of the Stipple‐throated Antwren (E. haematonota), which was found in the southern lowland rainforest of Amazonian Peru. The closed and globular nest was located 0.33 m from the ground, and was laterally supported by palm fronds. The single egg was off‐white and partially covered by dark magenta spotting. The nest and egg descriptions match other Epinecrophylla, but differ from Myrmotherula. The results support the split of Epinecrophylla from Myrmotherula.
RESUMEN ∙ Primera descripción del nido y huevo del Hormiguerito Dorsirrojo (Epinecrophylla haematonota) en Perú ∙ La biología de casi todas las especies de hormigueritos del genero Epinecrophylla es muy poco conocida. Aquí describo el primer nido y huevo del Hormiguerito Dorsirrojo (E. haematonota), encontrado en el sur de la selva amazónica del Perú. El nido cerrado y de forma globular estaba ubicado a 0,33 m del piso, con soporte lateral de cañas de palma. El único huevo era blanco con manchas magentas. La descripción del nido y huevo es similar a las de otras especies de Epinecrophylla, pero diferente de Myrmotherula. Estos resultados apoyan la identidad de Epinecrophylla como género separado de Myrmotherula.
