EA23878AFFCDFFB8FF5CFCB6FCFB8D38.taxon	discussion	Remarks. Viraktamath & Yeshwanth (2024) adequately described and illustrated this species. This species has the aedeagal shaft similar to that of B. distanti Viraktamath & Yeshwanth and B. albilateralis Maldonado-Capriles, but can be differentiated by the aedeagal apex in lateral view is rounded in B. manipurensis and B. albilateralis, the aedeagal shaft is smooth medially in former and toothed in the latter. In B. distanti aedeagal shaft is smooth medially as in B. albilateralis but the apex in lateral view is pointed.	en	Xue, Qingquan, Nyima, Tenzin, Da, Wa, Zhang, Yalin (2025): Taxonomy of eurymeline leafhoppers from Xizang, China (Hemiptera: Cicadellidae) with two new genera and three new species.

EA23878AFFCBFFBEFF5CFD21FEBC8CED.taxon	discussion	Remarks. Yarlungocerus gen. nov. resembles the Oriental and Australian genera Idioscopus, Amritodus and Busoniomimus in the texture of the crown and pronotum. However, the new genus differs from these genera in having a rounded distal half of the male pygofer compared to the narrow and most often angularly rounded pygofer apex in these genera. The new genus also differs from Idioscopus in not having apical or subapical processes on the aedeagal shaft (processes present in Idioscopus); from Amritodus in the absence of a well-developed preatrium and the aedeagus not S-shaped (aedeagus in Amritodus is S-shaped and has a well-developed preatrium); it differs from Busoniomimus in lacking an angular ventral projection on the male pygofer and the aedeagal shaft is not pustulate (male pygofer has an angular ventral projection and the aedeagal shaft in majority of species is pustulate in Busoniomimus).	en	Xue, Qingquan, Nyima, Tenzin, Da, Wa, Zhang, Yalin (2025): Taxonomy of eurymeline leafhoppers from Xizang, China (Hemiptera: Cicadellidae) with two new genera and three new species.

EA23878AFFC5FFB3FF5CFC97FB398A93.taxon	etymology	Etymology. The name of the genus is derived from Xizang, China where the type species was collected; gender masculine.	en	Xue, Qingquan, Nyima, Tenzin, Da, Wa, Zhang, Yalin (2025): Taxonomy of eurymeline leafhoppers from Xizang, China (Hemiptera: Cicadellidae) with two new genera and three new species.

EA23878AFFC5FFB3FF5CFC97FB398A93.taxon	discussion	Remarks. Xizangocerus gen. nov. resembles Amritodus Anufriev in the shape of the aedeagus and the structure of the female valvulae I and II, but differs in having (i) forewing with r-m 1 cross vein (absent in Amritodus); (ii) the hind basitarsus with three platellae (four in Amritodus); (iii) segment X with well-developed long internal process (process short and stout in Amritodus) and (iv) female sternite VII long with truncate posterior margin (sternite VII short with concave posterior margin in Amritodus). Viraktamath & Hongsaprug (1990) described a species, Idioscopus thailandensis Viraktamath & Hongsaprug from Thailand (Dio Ang Kand, Chiangmai), and our careful examination of the description and male genitalia figures suggests that it belongs to this new genus, so we propose it as a new combination here Xizangocerus thailandensis (Viraktamath & Hongsaprug) comb. nov.	en	Xue, Qingquan, Nyima, Tenzin, Da, Wa, Zhang, Yalin (2025): Taxonomy of eurymeline leafhoppers from Xizang, China (Hemiptera: Cicadellidae) with two new genera and three new species.
