Neurostigma Enderlein, 1900 (Psocodea: ‘Psocoptera’: Epipsocidae) from Brazilian Amazon Rainforest: new species and variations in forewings

Five new species of Neurostigma collected in the Brazilian Amazon Rainforest are described and illustrated: Neurostigma alfonsoi sp. nov., N. patriciae sp. nov., N. angelicum sp. nov., N. spinosum sp. nov. and N. willkeniae sp. nov. The first record of Neurostigma for the Brazilian state of Rondônia is included, along with an unpdated distribution map of male specimens of Neurostigma. An updated identification key of males of the genus is provided. Now, the number of species of Neurostigma recorded for Brazil has increased to 12, with two of them also occurring in Colombia. With this study, we significantly contributed to the knowledge of the diversity of the genus, which increased to 19 species.
