Atheta (Microdota) palleola : Palm 1970 : 186; Pasnik 2001 : 209; Smetana 2004 : 387 (as valid species). Material examined. Syntype, 4 exx., labeled as follows: '5451, pallola Er. Berol. Weis.'. NORTH KOREA: 2 exx., Korea, Jongak-san Pnjongjang-si, lg. Pawlowski, 8.1971 [North Korea, Pyeongannam Prov. Pyeongyang-si, Mt. Yongaksan, viii.1971, J. Pawlowski]; 4 exx., Korea 1-3.6.1974 Sujang-san Mt. Exp. Inst.Zool.Cr. [North Korea, Hwanghae Prov. Mt. Suyangsan, 1-3.vi.1974, ISEA]. Description . Length 1.4-1.8 mm. Body (Fig. 9) slender and parallel-sided; surface glossy and densely pubescent, with fine microsculpture. Body usually yellowish brown; head and abdominal tergites VI-VII darker than other parts. Head. Slightly transverse, approximately 1.1-1.2 times wider than long, widest across eyes, slightly narrower than pronotum; eyes moderate in size and prominent, about 1.0-1.1 times longer than tempora; infraorbital carina incomplete; gular sutures moderately separated, diverged basally. Antennae dilated apically; antennomeres 1-3 elongate, 1 longest, 4-10 distinctly transverse, 11 longer than wide, slightly longer than preceding two combined. Thorax. Pronotum slightly transverse, approximately 1.2-1.3 times wider than long, widest at apical third; pubescence directed anteriorly in midline. Elytra slightly transverse, slightly wider than pronotum, elytron approximately 1.7 times longer than wide, pubescence directed posteriorly and postero-laterally; postero-lateral margin almost straight; hind wings fully developed. Legs. Slender and long, with dense pubescence and setae; tibiae with two spurs at apex; meso- and metatarsomeres 1-4 subequal in length. Abdomen. Parallel-sided, widest at middle; surface glossy and densely pubescent; male tergite VIII with 4 macrosetae on each side of midline, posterior margin broadly truncate, slightly emarginate; posterior margin of male sternite VIII rounded. Genitalia. Median lobe oval, apical process convergent at apex in ventral aspect. Apical lobe of paramerites elongate. Spermatheca with large bursa, duct long and slender, coiled apically. Distribution. Korea (North), Europe (Austria, Belgium, Bulgaria, Croatia, Czech Republic, Finland, France, Great Britain, Germany, Hungary, Italy, The Netherlands, Norway, Poland, Romania, Slovakia, Sweden and Switzerland) and Russia (Caucasus and East Siberia). Remarks. This species was recorded by Pasnik (2001) in North Korea and a dissected specimen was unavailable. Accordingly, we could not describe the mouthparts and aedeagus in detail. This species has been known to occur on disc fungi ( Palm 1970 ).
