Muhammad, Amira Aqilah, Tan, Ming Kai, Abdullah, Nurul Ashikin, Azirun, Mohammad Sofian, Bhaskar, Dhaneesh & Skejo, Josip, 2018, An annotated catalogue of the pygmy grasshoppers of the tribe Scelimenini Bolívar, 1887 (Orthoptera: Tetrigidae) with two new Scelimena species from the Malay Peninsula and Sumatra, Zootaxa 4485 (1), pp. 1-70 : 20

Genus Discotettix Costa, 1834

Discotettix : Costa 1864, Hancock 1907a, Willemse 1930, Günther 1938a, Blackith 1992, Yin et al. 1996, Otte 1997, Mahmood et al. 2007, Skejo & Bertner 2017.

Mnesarchus: Stål 1877 , Willemse 1930.

Discotettix (Mnesarchus) : Kevan 1966.

Type species: Discotettix armatus , synonym of D. belzebuth

Composition and distribution. Six species, in Mindanao—the Philippines ( D. scabridus ), Borneo ( D. belzebuth and D. shelfordi ), Sumatra ( D. selysi ), Metawei ( D. doriae ) and southern Peninsular Malaysia ( D. selangori ).

Notes. The genus has recently been assigned to Scelimenini ( Skejo & Bertner, 2017), but the formal synonymization of Discotettiginae and Scelimeninae and revision of the genus Discotettix will soon be published (Skejo, Pushkar & Tumbrinck in preparation). The genus is characteristic within Scelimenini in having widened subapical antennal segments (6th to 8th or 9th) and large pronotal projections. It is closely related to Paragavialidium Zheng, 1994 . Discotettix belzebuth ( Serville, 1838) ( Fig. 8 ) is the species with the highest pronotal projections.
