Tegotettix cristiferus (Günther, 1935)

Xistra cristifera: Günther 1935 .

Tegotettix cristiferus: Günther 1938a, Blackith 1992. Type material examined. 1♀ SYNTYPE Midden O-Borneo 18.XI.1925. Leg. H. C. Siebers (MTD). Photographs of the female syntype are available online in OSF. According to Günther (1935) one more syntype (from Java) is deposited in National Museum Szczecin, and was not examined in this study.

Type locality: Middle East Borneo.

Notes. The species resembles Xistra species more than Tegotettix members. Of Tegotettix members, it is somewhat close to Bornean T. siebersi . It could be in future moved back to the genus Xistra . It is also similar in morphology to T. sagittarius and T. corniculatus, differing from them in higher fastigial horns, and compressoelevated median carina (as discus) between the shoulders. The species has very depressed vertex, it lacks pronotal projections homologous to those in Tegotettix species (more specifically to T. armatus, T. bufocrocodil and T. celebensis). Detailed revision of more specimens is needed to assess true taxonomic position of this species.
