Abstract:

The subfamily Polyphaginae is assessed using phylogenetic methodology, which has resulted in a revised concept of this taxon which includes the Homoeogamiidae, Mononychoblattidae and Cryptocercidae. A redescription of the subfamily is offered, and synapomorphic characters are provided to support the monophyly of both the Polyphaginae and the family Poiyphagidae. A phylogenetic hypothesis of relationships of polyphagine genera is proposed, based on fifty morphological characters polarized in reference to six outgroups (one tree, CI = 0.79, RI = 0.87). The Polyphaginae now includes the following sixteen genera: Anisogamia, Arenivaga, Cryptocercus, Eremoblatta, Ergaula, Eucorydia, Eupolyphaga, Hemelytroblatta, Heterogamisca, Heterogamodes, Homoeogamia, Leiopteroblatta, Mononychoblatta, Nymphytria, Polyphaga and Therea. Three genera are removed from the Polyphaginae: Austropolyphaga, Miroblatta and Polyphagoides. One new generic synonymy is proposed: Psammoblatta as a synonym of Hemelytroblatta. The subgenus Heterogamisca is elevated to generic status. The genus Nymphytria is removed from synonymy with Mononychoblatta, and restored to generic rank. The subfamily Polyphaginae in its present sense has a large ecological range, including deserts of North America and the Old World, and tropical and temperate biomes such as dry and rain forests of Africa and Asia, but excluding Australia.
