Changes in the genus Euplocania (Psocodea: Ptiloneuridae): invalidation of the species group Marginata and establishment of the species group Uariniensis, with description of two new species

The recent examination of the morphology of the wings, hypandrium and phallosome, of Brazilian and Colombian species of Euplocania, initially assigned to the species group Marginata, suggested that the group was wrongly established and therefore, must be removed. As a consequence, the new species group Uariniensis is proposed to include E. atlantica Silva-Neto, E. uariniensis Silva-Neto, Garcia Aldrete & Rafael and E. macuxi Pereira, Silva-Neto & Boldrini, in addition to the two species described in this paper: E. guticortesorum n. sp. and E. wilsoni n. sp. The number of species in Euplocania is raised to 53. A key for the determination of the species (males) of the group Uariniensis is also included.
