Systematics of Asiopsocidae (Psocoptera) Including Pronotiopsocus Amazonicus N. Gen. N. Sp.
Abstract
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 Gunther 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.Downloads
