Heterelmis comalensis new species is described from Comal Springs, one of the headwaters of the Comal River, in New Braunfels, Texas. It is apparently endemic, hind wings brachypterous, and smaller in size than any other species known from the United States (1.7 to 2.1 mm in length, 0.8 to 0.91 mm in breadth). It is closest to Heterelmis glabra (Horn) from which it differs in body contour and in size, H. glabra being 1.9 to 2.35 mm long and 1.0 to 1.17 mm wide.
