TABLE 1. Comparative measurements of the morphological traits of five Tegotettix species: the type species (T. armatus) from the T. armatus species group, and four species of the T. cristiferus species group, including the new species, T.derijei sp. n. All measurements are expressed in millimeters. N/A—measurement not available, as the required morphological trait on the specimen has been broken. (BL—body length, PL—pronotum length, PW—pronotm width, HW—hu-meral angles width, PH—pronotum height, FFL—fore femur length, FFW—fore femur width, MFL—mid femur length, MFW—mid femur width, HFL—hind femur length, HFW—hind femur width, VW—vertex width, EW—compound eye width, FH—fastigial horn height, AL—antenna length).
