Description
Summary:Pronotiopsocus n. gen. is described with P. amazonicus n. sp. as the type species. The new genus is placed in family Asiopsocidae together with Asiopsocus Günther and Notiopsocus Banks. The 3 genera are diagnosed. Their probable plesiomorphous characters are derived by outgroup comparison with superfamily Caecilioidea. These characters are taken to represent a hypothetical common ancestor of the Asiopsocid genera, which is used to reconstruct the phylogeny of these genera. Pronotiopsocus represents one line of the phylogeny with Notiopsocus and Asiopsocus representing a sister lineage. Geographical distributions suggest great antiquity with a Pangaean origin of the family. The furcation of the lineage bearing Notiopsocus and Asiopsocus may have coincided with the initial breakup of Pangaea. Absence of Notiopsocus from India, Madagascar, and Australia may be due to insufficient sampling of these regions or to the timing of origin and spread of the genus relative to the breakup of Gondwanaland. /// Pronotiopsocus gen. n. se describe con el tipo P. amazonicus sp. n. El nuevo género se coloca en la familia Asiopsocidae, junto con Asiopsocus Günther y Notiopsocus Banks. Los 3 géneros se diagnosan. Sus caracteres plesiomorfos probables se deriven por comparación con la superfamilia Caecilioidea. Éstos caracteres se toman como representantes de un antepasado común hipotético de los géneros asiopsócidos, empleado para la reconstrucción de la filogenia de éstos géneros. Pronotiopsocus representa una linea de la filogenia con Notiopsocus y Asiopsocus representando una lineahermana. Las distribuciones geográficas sugeren gran antiguidad con un origen Pangean de la familia. La furcación de una linea llevando Notiopsocus y Asiopsocus puede haber coincidido con la fragmentación inicial de Pangaea. La ausencia de Notiopsocus de India, Madagascar, y Australia puede ser debido a la falta de investigación en éstas regiones, o puede ser debido al patrón temporal del origen y distribución de aquel género en relación a la fragmentación de Gonduanalandia.
