D e s c r i p t i o n. Measurements (mm) of holotype: length of antenna: 0.73; maximal head width (including eyes): 0.44; head length 0.29; maximal width of pronotum: 0.51; length of pronotum (measured along its midline): 0.36; length of elytra at suture: 0.41; maximal width of elytra (combined width of each elytron when elytra closed along suture): 0.73; total length of body (from anterior margin of labrum to posterior margin of tergite VIII): 2.2.

Coloration: head dark-brown; pronotum pale brown with narrow pale brown margin at base and laterally; elytra yellow; abdomen pale brown, abdominal tergites VI and VII dark brown; mouthparts, antennae and legs yellow.

Head smooth, transverse, 1.52 times as wide as long, vertex with 5 or more sparse, small, round, distinct punctures on each side; microsculpture absent.

Pronotum smooth; strongly transverse, 1.41 times as wide as long and 1.16 times as wide as head; posterior angles and posterior margin of pronotal disc rounded; in middle and lateral sides of pronotal disc with sparse, scattered, small, rounded punctures, in the middle with 2 longitudinal rows of 5 round, distinct punctures each; microsculpture absent.

Elytra smooth and glossy; 1.43 times as wide as pronotum; with sparse, round, small punctuation; microsculpture absent; with sparsely distributed fine setae.

Abdomen: posterior margin abdominal tergites, each, 1 row longitudinal and narrow striae; punctation hardly distinct or absent; abdominal tergites, each, with dense and distinct microsculpture. Male: middle of posterior margin of 8th tergite with wide incision bordered by 2 short, wide, apically weakly pointed, curved inwards appendages and with 2 short, pointed teeth ( fig. 3 , 1 ). Aedeagus ( fig. 3 , 2 ).

C o m p a r a t i v e n o t e s. Based on the similar morphology of the male primary and secondary sexual characters Gyrophaena plutenkoi Glotov , sp. n. is similar to G. simplicitatis Pace, 2003 and allied species ( G. fusicornis Eppelsheim, 1887 ). It can be reliably distinguished from these species by the shape of the male sternite VIII and by the shape of the aedeagus. For illustrations of the aedeagi of G. simplicitatis see Pace (2003).

E t y m o l o g y. The new species is named for Andrey Plutenko ( Russia, Smolensk), who collected the holotype and numerous specimens of Gyrophaena in the Russian Far East.
