Emended diagnosis.

Differs from all other Drymadusini genera in China by its male cercus being strongly incurved at or after its middle with acute apex, with a basal inner tooth (Figs 2 View Figure 2 , 6 View Figure 6 , 9 View Figure 9 , 12 View Figure 12 ); median carina faintly indicated in prozona and absent in metazona; male tegmen about twice as long as pronotum; and female tegmen equal to or slightly longer than pronotum. Furthermore, Sichuana differs from Uvarovina Ramme, 1939, Ptosoproctus Shen, Yin & He, 2021, and Eulithoxenus Bey-Bienko, 1951 by its prosternum with a pair of spines (Figs 4 View Figure 4 , 8 View Figure 8 , 11 View Figure 11 , 14 View Figure 14 ). Differs from Atlanticus Scudder, 1894, Eulithoxenus , Ptosoproctus , and Uvarovina by its ovipositor being decurved (Figs 2 View Figure 2 , 6 View Figure 6 , 9 View Figure 9 , 12 View Figure 12 ). Differs from Atlanticus , Eulithoxenus , Mongolodectes Bey-Bienko, 1951, Paratlanticus Ramme, 1939, Ptosoproctus , and Uvarovina by its lateral carina being distinct in metazona and faintly indicated on prozona (Figs 2 View Figure 2 , 6 View Figure 6 , 9 View Figure 9 , 12 View Figure 12 ). Differs from Kansua Uvarov, 1933, Paratlanticus , Ceraeocercus Uvarov, 1910 by dorsal side of protibia only with external spurs, and dorsal side of mesotibia with spurs on both sides. Differs from Kansua Uvarov, 1933 by its smooth pronotum ( Heller and Liu 2016; Liu 2013; Liu 2015; Liu et al. 2019; Shen et al. 2021).
