Diagnosis
Diagnosis. Medium Sinophasma. Closely related to S. jinxiuense Chen & He, 2008 [Guangxi, China] but S. bii sp. nov. [Yunnan, China] is well distinguished by broadly emarginated hind margin of the anal segment of male, which has the postero-lateral angles square in shape, and with elongate praeopercular organ on seventh sternum in female. Also closely related to S. atratum Chen & He, 2000 [Guangxi, China] but S. bii sp. nov. [Yunnan, China] can be separated by the postero-lateral angles of ninth tergum rounded in male and gonapophyses reaching to the base of anal segment and alae reaching to sixth tergum in female.

Diagnosis
Diagnosis. Medium Sinophasma. Closely related to S. mirabile Günther, 1940 [[[Type]] from Fujian, also found in Guangdong, Guangxi, Hong Kong, Hunan and Zhejiang, China] but well distinguished by broadly emarginated hind margin of the anal segment, which parallel to ninth tergum, flattened cerci, and posteriorly elongated hind margin of poculum in male and deeply emarginated hind margin of the anal segment in female.

This is probably a green species in nature based on the green left metafemur and left metatibia of one paratype female. The colouration of most Sinophasma species is green on body, legs and part of wings, which is a colour that is easily lost due to the original collecting and preserving methods. The description of the colouration is based on the dried specimens.
