Diagnosis. This species resembles E. aenea , E. forceps , E. coerulea , and E. gemma by having two spots on the lateral margins of tegmina, but it can be distinguished from E. aenea and E. forceps by the arrangement of the white pubescence (band shaped in E. linglong , while circle-shaped in E. aenea and E. forceps ); it differs from E. coerulea by the white pubescence (with white pubescence in E. linglong while without in E. coerulea ); it can be distinguished from E. gemma by the larger body size (more than 10 mm without tegmina in E. linglong , while less than 10 mm in E. gemma ).
