Remarks.
The species belongs to
Dianous chinensis
complex. It is similar to
D. bashanensis
Zheng, 1994
and
D. gonggamontis
Puthz, 2000
both from
Sichuan
, but can be distinguished from them by smaller and denser punctation of head, pronotum lacking pubescence and longer longitudinally rugae around the elytral marks, from
D. gonggamontis
also by weaker blue shimmer of entire body. The species is new to
Sichuan
.
