The number of species of Indiopsocus known (i.e. published in print) from Texas is raised from three to seven. Three of the newly recorded species are new and are here named and described. Distribution records are given for them within and outside of Texas. Texas distribution records are given for the previously known species. The series of syntypes of Indiopsocus texanus (Aaron) in the Philadelphia Academy of Natural Sciences and in the Cornell University Insect Collection was examined, and the single male in the series (Cornell Collection) was selected as lectotype for this species, the generotype of Indiopsocus. A brief phenetic classification of Indiopsocus is included with the known species listed in each category. A key to the species of Indiopsocus recorded from Texas and eastward to the Atlantic coast is included.
