Yunnantettix thaicus Storozhenko & Pushkar, 2015

Notes. This species is similar to Y. nanensis sp. nov.. According to the original photographs provided (Storozhenko & Pushkar 2015): median carina of vertex not protruding forward, in lateral view vertex together with frontal costa exactly arcuate (but the original line drawing provided indicates that in lateral view vertex together with frontal costa obtusely rounded and protruding forward); posterior margin of female subgenital plate truncate (but the line drawing provided indicates posterior margin gradually contracted backwards). Notably, female size (body length, width of vertex than one eye, and lengths of both hind femur and pronotum) is smaller than male (Storozhenko & Pushkar 2015), which is unusual. In Tetrigiade, female pronotum may equal or shorter than male sometimes, such as Bolivaritettix anhuiensis Zhang, Zha & Zheng, 2014 , but little is reported that female body length, width of vertex than one eye, length of hind femur are smaller or shorter than male. Considering the holotype (♂, Nakhon Ratchasima Province) and the paratype (only 1♀, Loei Province) coming from two different regions of Thailand, that are 300 km distant, their different ratios of width of scutellum between antennal grooves than diameter of first segment of antenna (male 2.5 times while female 2.0 times), together with their unusual body sizes, we doubt the two specimens may represent two different species. Shortly afterwards, Storozhenko & Dawwrueng (2015) reported another distribution of this species (1♂ 2♀, Chiang Mai Province, Thailand), but they did not give any morphological description.
