Popis: Gyrophaena (Gyrophaena) transversalis A. Strand, 1939 Strand, 1939: 109. Material examined. Type. Lectotype Ơ Gyrophaena transversalis (here designated): “Austr. inf. Umgb. Krems a. D. Th. v. Wanka / TYPUS Gyrophaena transversalis A. Strand [pale red label] / NHMO: type collection 1000175369 / LECTOTYPE Ơ Gyrophaena transversalis A. Strand, 1939 S. Glotov des. 2011 [red label]” (NHMO). Redescription. Measurements (in mm): length of antenna: 0.60; maximal head width (including eyes): 0.46; head length 0.28; maximal width of pronotum: 0.56; length of pronotum (measured along its midline): 0.32; length of elytra at suture: 0.41; maximal width of elytra (combined width of each elytron when elytra closed along suture): 0.72; total length of body (from anterior margin of labrum to posterior margin of tergite VIII): 2.0. Coloration: head dark brown, pronotum dark brown, elytra yellow or pale brown, with slightly darkened posterior angles; abdomen pale brown, abdominal tergites V–VI brown; mouthparts, antennae and legs yellow. Head transverse, vertex with 8–10 sparse, small, round, distinct punctures; 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. Pronotum strongly transverse, posterior angles and posterior margin of pronotal disc rounded; with round, distinct punctures each; microsculpture dense and distinct. Elytra with dense and fine punctuation; microsculpture dense and distinct; with sparsely distributed fine setae, microsculpture dense and distinct. 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, 9). Aedeagus (fig. 2, 8). D i s t r i b u t i o n. Europe, Eastern Siberia (Schülke & Smetana, 2015). Comments. The original description of G. transversalis is based on 13 syntypes collected at “Umgebung von Krems a. D. in Nieder-Ӧnsterreich” (is a city in Lower Austria) by “Th. v. Wanka” (Strand 1939). The only male syntype found in the collections of NHMO is designated as lectotype for the better fixation of the identity of the name Gyrophaena transversalis A. Strand, 1939.
