Genus Tegotettix Hancock, 1913 View in CoL

Justification of the generic placement of the new species. The new species is placed in the genus Tegotettix Hancock, 1913 , with the type species T. armatus Hancock, 1913 from Borneo. T derijei sp. n. is morphologically most similar to T. cristiferus ( Günther, 1935) , known only from the type series originating from central-east Borneo. The two species share almost all morphological traits, except for those related to the arrangement and height of the pronotal projections. Thus, the new species is placed within the genus Tegotettix . At first sight, it is also similar to the type species, but as they do not share the traits related to the head (e.g., the position of the bifurcation of the frontal costa), this superficial similarity could probably be a result of convergent evolution. With the newly proposed species, the genus Tegotettix currently includes ten species; here, we briefly review the current taxonomy of the genus. The genus can be divided into three species groups, each of which includes species of very similar morphology. However, not a lot of characters unite the three groups within Tegotettix , and future research could result in the erection of three separate genera. The character that should unite all Tegotettix species are its high fastigial horns, but even to this rule, exceptions do exist, i.e., the low fastigial horns in T. sagittarius and T. novaeguineae .
