Bernhauer Collection / HOLOTYPE ♀ Gyrophaena semipunctata Bernhauer, 1926 rev. S. Glotov 2010 [red label]” ( FMNH ). Redescription. Measurements of the holotype (in mm): length of antenna: 0.73; head width (including eyes): 0.49; head length: 0.35; width of pronotum: 0.59; length of pronotum: 0.39; length of elytra at suture: 0.39; width of elytra (combined width of each elytron when elytra closed along suture): 0.74; total length of body (from anterior margin of labrum to posterior margin of tergite VIII): 2.5. C o l o r a t i o n: head brown; pronotum pale brown; elytra yellow; abdomen pale brown, abdominal tergites VI and VII dark brown; mouthparts, antennal segments I–XI and legs yellow. Head strongly transverse, 1.40 times as wide as long, vertex with 4 moderately large, round punctures on each side; microsculpture absent. Antennae long; antennal segment I long and fat; segment II narrower and long but 0.56 times shorter than segment I; segment III slightly elongate but narrower and 0.80 times shorter than segment II; segment IV small and short, almost square; V–X slightly transverse and slightly widened towards apex. Pronotum strongly transverse, 1.51 times as wide as long and 1.20 times as wide as head; posterior angles and posterior margin of pronotal disc rounded; in the middle with 2 longitudinal rows of 5 (3 moderately large and 2 small) round, distinct punctures each; in the middle and near posterior margin with 1 moderately large, round, distinct punctures each, lateral sides; microsculpture absent. Elytra 1.25 times as wide as pronotum; with sparse, small, round punctuation; microsculpture hardly distinct. Abdomen: abdominal tergites, each, with dense, small, round punctuation; posterior margin, each, abdominal tergites with 1 row longitudinal and narrow striae. Female: posterior margin of tergite VIII rounded, without incision or appendages. Spermatheca (fig. 3, 2 ). Male: unknown. D i s t r i b u t i o n. China ( Liaoning ). Comments. The original description of G . semipunctata Bernhauer, 1926 was based on a single specimen collected from “Chikuanshan in der S. Mandschurei” (now a province of Liaoning , China ) collected by Dr. O. Staudinger or collectors from his company ( Bernhauer, 1926 ). In the original description, it was indicated to be a male, but during dissection of the specimen, it turned out that this is a female; its spermatheca was embedded into euparal.
