Type species: Xizicus xizangensis Jiao & Shi, 2013

Generic diagnosis: Body small and slender of this tribe. Fastigium of vertex stout, obtusely rounded apically, dorsally furrowed. Last two segments of maxillary palpi about equal in lengths. Lateral pronotal lobes notched on posterior margin. Tegmina fully developed, hind wings usually longer. Tibial tympana open on both sides, the apex of hind femora bearing 3 pairs of apical spurs. Posterior margin of male 10th abdominal tergite not specialized. Male cerci varied, male genitalia completely membranous. Fastigium verticis black; pronotal disc with a longitudinal yellowish-brown band in the middle, anterior margin of pronotum with 1 pair of black brown spots, metazona also with 1 pair of black brown spots or absent in some specimens.

Discussion: For some time, we have known that Xiphidiopsis quardrinotata was a Meconemopsis because of the black dorsum of fastigium vertices. Actually, the photos of Meconemopsis borellii on OSF clearly indicate its relationship with Alloteratura . Besides, we misidentified the female from Xizang as Xiphidiopsis quadrinotata until Shi, Bian & Zhou (2016) clarified they are different.
