 sparsely punctate. Elytra with narrow, lightly impressed stria?, which are 

 finely, not closely punctate. Length 3.5-5 mm.

and rather sparse pubescence. Antenna? with joints 3 to 9 almost twice as 

 wide as long. male, or slightly wider than long, female. Eyes small, sep- 

 arated on the front by about five times their longest diameter. Thorax
