TABLE 3. Morphologically diagnostic characters separating Gonotyles Kéler, 1940, Oulocrepis Kéler, 1940, Solenodes Kéler, 1940, Complectodes new genus, and Majiodes new genus. Note that the species placed as incerta sedis within Gonotyles are not included in the comparison below, as they are poorly known (see text).
