M a t e r i a l e x a m i n e d. Type. Holotype Ơ: “ RUSSIA: Primorie reg. [Primorsky Kray], 20 km N Artyom [town] env., 200–350 m, Prevalsky. Kamenuschka 15.05– 6.06.2002, leg. A. Plutenko [white label] / Sammlung M. Schülke, Berlin [white labels] / Holotypus Gyrophaena anastasiarum sp. n. det. S. Glotov, 2021 [red label]” ( MNHB).

D e s c r i p t i o n. Measurements (in mm): length of antenna: maximal head width (including eyes): 0.41; head length: 0.26; maximal width of pronotum: 0.41; length of pronotum (measured along its midline): 0.31; length of elytra at suture: 0.39; maximal width of elytra (combined width of each elytron when elytra closed along suture): 0.61; total length of body (from anterior margin of labrum to posterior margin of tergite VIII): 1.8.

Coloration: head dark brown, glossy; pronotum brown; elytra and abdomen brown; antennae, mouthparts, legs and antennal segments yellow or pale brown.

Head strongly transverse, 1.5 times as wide as long, vertex with 7 moderate, round, distinct punctures scattered on each lateral side.

Pronotum transverse, 1.3 times as wide as long and the same width as head, with moderate punctation of round, scattered, in the middle with 2 longitudinal rows of 3 large round, distinct punctures each; posterior edge of pronotum bordered; posterior angles and posterior margin of pronotal disc rounded; microsculpture indistinct or absent.

Elytra 1.3 times as wide as pronotum; with even, sparse and small punctures; microsculpture indistinct.

Abdomen narrower than elytra, with dense and distinct microsculpture; abdominal tergites each, with indistinct, small, round punctuation; male: posterior margin of tergite VII with a row of longitudinal and narrow striae; posterior margin of tergite VIII with wide incision bordered by 2 short, wide, apically weakly pointed, inward curved appendages and medially with 2 short and thin appendages ( fig. 1, 1 ). Aedeagus ( fig. 2 , 1 ). Female: unknown.

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 anastasiarum Glotov , sp. n. is similar to G. triquetra Weise, 1877 and allied species, G. bucranium Pace, 2007 and G. monstruosa Pace, 2007 . It can be reliably distinguished from these species by the shape of the male sternite VIII and aedeagus. For illustrations of the aedeagi of G. bucranium and G. monstruosa see Pace (2007).

Etymology. The new species is named after my daughter and my wife, both Anastasia.

D i s t r i b u t i o n. Russia (Primorsky Kray).
