Adult Markings: Members of the genus Nannaria are generally smaller with more subdued coloration than other Xystodesmids. Adults of Nannaria nessa can be separated from the geographically close and morphologically similar species N. austricola and N. spalax by the following characters. Acropodite medial flange lobed, rather than laminate and with a short, triangular tip medial flange as in N. spalax sp. nov. Acropodite tip medial flange absent, not lobed as in N. austricola. Prefemoral process only slightly curving and with a notch on its medial side near midpoint, not curving laterally as in N. austricola or thick and with a jagged medial margin as in N. spalax. Tergites with two paranotal red spots, collum outlined in red, and tergites with background black.
