Tegotettix siebersi Günther, 1938

Tegotettix siebersi: Günther 1938a , Steinmann 1970, Otte 1997.

Type material examined. 1♀ SYNTYPE Midden O-Borneo 15.IX.1925. Leg. H. C. Siebers, 1♂ SYNTYPE Midden O-Borneo 7.VIII.1925. Leg. H. C. Siebers (MTD). Photos of the syntypes are available in OSF.

Type locality: Middle East Borneo.

Notes. The species is morphologically similar to T. celebensis , but also somewhat to T. cristiferus . Fastigial horns are high, elevated FM+PM are absent (by this character it can be easily distinguished from T. armatus ), there are not elevated MMs (MM2 to MM6) on the median carina, and humeral angles are much weaker than in T. armatus . Günther (1938) compared the species to T. sagittarius and T. corniculatus , which are very different morphologically and resemble Xistra species (and are probably members of that genus). In dorsal view , species is similar to T. celebensis . Since taxonomy of the genus is still complicated, not a lot can be said on the position of this and related species.
