Redescription. Measurements (in mm): length of antenna: 0.91; maximal head width (including eyes): 0.63; head length: 0.48; maximal width of pronotum: 0.68; length of pronotum (measured along its midline): 0.48; length of elytra at suture: 0.51; maximal width of elytra (combined width of each elytron when elytra closed along suture): 0.97; total length of body (from anterior margin of labrum to posterior margin of tergite VIII): 2.5.

Coloration: head brown; pronotum pale brown; elytra yellow or pale brown, with slightly darkened posterior angles; abdomen pale brown, abdominal tergites VI–VII brown; mouthparts, antennae and legs yellow.

Head strongly transverse, vertex with 6 or more small, round, distinct punctures on each side; microsculpture dense and distinct. Antennae length: antennal segment I long, strongly widened towards apex; segment II long, narrower and shorter than segment I; segment III narrower and shorter than segment II; segments IV–X transverse, 1.5–2.0 times as wide as long, all segments almost parallel-sided.

Pronotum strongly transverse, posterior angles and posterior margin of pronotal disc rounded; in middle and lateral sides of pronotal disc with sparse, scattered, small, rounded punctures, microsculpture dense and distinct.

Elytra with dense and fine punctuation; microsculpture dense and distinct; with sparsely distributed fine setae, microsculpture indistinct or absent.

Abdomen: abdominal tergites, each, with relatively indistinct or absent, fine punctuation. Male: 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 , 6). Aedeagus ( fig. 2 , 5).

D i s t r i b u t i o n. Europe, Asia Minor, Middle Asia ( Schülke & Smetana, 2015).

Comments. The original description of G. munsteri is based on 3 syntypes collected “in Sandnes in Drangedal” (is a city in Norway) by Münster and 4 syntypes collected “in Invinhoe in England ”, by Williams ( Strand, 1935). One male syntype found in the collection of NHMO is designated here as lectotype for the better fixation of the identity of the name Gyrophaena munsteri A. Strand, 1935 .
