Diagnosis
This species seems most closely related to the Trans-Palaearctic species Seladonia (Pachyceble) tumulorum and the Holarctic species Seladonia (Pachyceble) confusa in having similar body sculptures and male genitalia. However, it differs these allied species by the following key:
Based on the published works of Dawut and Tadauchi (2003)[1], Ebmer (2005)[2], Pesenko (2006)[3], Pesenko and Wu (1997)[4], and the specimens examined for this study, this species is also separated from the other Chinese species by the combination of following characters: HL/HW ratio= 0.88–0.90 in female; inner hind tibial spur of female with slender 7–8 teeth; upper gonostylus of male genitalia with slender medial lobe; and lower gonostylus of it long and large.Description

All coxae and trochanters black; fore and middle femora mostly yellow; hind femur mostly black except for apical 1/4; all tibiae and tarsi yellow. Wings transparent, veins and stigma pale yellowish.
