Sinotympana Lee 2009: 87 .

TYPE SPECIES. Sinotympana incomparabilis Lee 2009: 88 . ( Nankunshan National Park, Guangdong Province, China)

DIAGNOSIS. This genus was originally differentiated compared to genera of the Dundubiina (Lee 2009) but was later reassigned to the Aolina (Lee and Emery 2014). A key to the genera of the Aolina was produced by Lee and Emery (2014) and updated with additional genera by Lee and Sanborn (2015) and Lee (2016). Sinotympana is distinguished from the other Aolina by the following group of characters in these keys: body length less than 3.2 times as wide as abdominal tergite 3, timbal cover with a minimal gap between timbal cover and cruciform elevation, male abdomen longer than distance between anterior postclypeus and posterior cruciform elevation, and the male opercula not extending to the posterior margin of sternite III with medial margins only slightly separated or slightly overlapped.

DISTRIBUTION. China (Guangdong) and Vietnam (Cao Bang).
