Two new species of cixiid planthoppers genus Tsauria Koçak & Kemal, Tsauria brevispina Zhi & Chen, sp. nov. and T. longispina Zhi & Chen, sp. nov., are described and illustrated from China and T. transspinus (Zhang & Chen, 2011) was removed to give the genus four species in total. The female genitalia of three species are described and illustrated for the first time. A key to all known species of Tsauria based on male genitalia, and a key to three species (except for T. major) based on female genitalia, are provided.

Herein, two new species: Tsauria brevispina Zhi & Chen, sp. nov. and T. longispina Zhi & Chen, sp. nov. are described and illustrated from China. Female genitalia of three Chinese species are described and illustrated for the first time. The genus now includes four species, and all from China. A key to all known species of Tsauria based on male genitalia, and a key to three species (except for T. major) based on female genitalia, are provided.

The specific name is derived from the Latin prefixes “brevi” and noun “spina”, referring to the ventral margin of aedeagal periandrium with an extremely short spinose process, which is the shortest of all spinose processes of the periandrium.
Male genitalia of T. brevispina sp. nov. is similar to T. cehengensis (Zhang & Chen), but differs in: (1) spinose process on ventral margin of periandrium being the shortest of all spinose processes of periandrium (in T. cehengensis, not the shortest one); (2) spinose process on left side near apex of periandrium being the longest, straight (in T. cehengensis, spinose process in the same position being the shortest, basal two-thirds stout and apical third arc-shaped curved); (3) medioventral process without bristles at apex (the latter with bristles); (4) forewing with 13 apical cells (the latter with 12 apical cells).
Female genitalia of T. brevispina sp. nov. is similar to T. cehengensis (Zhang & Chen), but differs in: (1) posterior vagina elongate (in T. cehengensis, the length of posterior vagina equal to the width); (2) sclerites dispersed both in ventral and dorsal view (in T. cehengensis, sclerites in ventral view mainly concentrated in the middle area and the ones in dorsal view mainly concentrated in left side); (3) Gonapophysis IX with one middle tooth, denticulate portion degenerated (in T. cehengensis, Gonapophysis IX with two middle teeth, denticulate portion with one small rounded odontoid).

The specific name is derived from the Latin prefixes “longi” and noun “spina”, referring to the ventral margin of aedeagal periandrium with an extremely long spinose process, which is the longest of all spinose processes of the periandrium.
Male genitalia of T. longispina sp. nov. is similar to T. brevispina sp. nov., but differs in: (1) spinose process on ventral margin of periandrium being the longest of all spinose processes of periandrium, straight (in T. brevispina, spinose process on ventral margin of periandrium being the shortest of all spinose processes of periandrium, hooked at apex); (2) spinose process on right side near apex of periandrium slightly curved, directed left-dorsocephalically at apex (the latter strongly curved, directed dorsocaudally at apex).
Female genitalia of T. longispina sp. nov. is similar to T. cehengensis (Zhang & Chen), but differs in: (1) wax plate divided by median keel (the latter widened laterally and without median keel; (2) posterior vagina elongate (in T. cehengensis, the length of posterior vagina equal to the width).
Tsauria cehengensis (Zhang & Chen, 2011) and T. major (Tsaur & Hsu, 1991) were distinguished mainly on the characters of the male genitalia; only the anal segment of T. major was illustrated for the female (
