Peyerimhoffia vagabunda (Winnertz) — Vilkamaa & Hippa (2005) : 474, Fig. 12; 476 Redescription . Male . Head : eye bridge 3–4 facets wide. Antenna slightly rough and dark brown; 4th flagellomere ( Fig. 6 E) about 2.3–2.6X as long as wide; with distinct neck; setae 4/ 5X as long as diameter of basal flagellomere. Maxillary palpus ( Fig. 6 D) one-segmented, short club-shaped and brown (second segment sometimes with fine vestigial), with 4–6 setae, patch of sensilla small. Thorax ( Fig. 6 G): dark, with moderately long setae. Posterior pronotum bare. Scutum with sparse dark setae without long lateral setae. Scutellum with 2 long and strong setae. Katepisternum slightly higher than wide. Wing ( Fig. 6 C) brown; posterior veins and wing membrane clearly without macrotrichia; stem of M 1.2X longer than Mfork; M-fork slightly triangular, M1 and M2 slightly curved; x = 1.0–1.5X length of y, bare; stem of CuA = 0.7–1.0X length of x; vein R1 = 0.8–1.0X length of R; R4+5 with macrotrichia dorsally; vein C = 2/ 3X length of w. Halter moderately short stemmed and brown. Leg pale yellow; apex of foretibia with coarse and dense setae group ( Fig. 6 F); claws untoothed. Abdomen : genitalia ( Fig. 6 A) brown, about 2.0X wider than high, and without basal lobe or ventral setae; base of gonocoxite semi-circular. Gonostylus ( Fig. 6 B) short and thickened, about 1.5–1.9X as long as broad, shape of gonostylus triangular, apical part of gonostylus with a long and strong tooth (with a long center seam without lobelike socket), tooth structure varying in length, but usually quite long, inner side of gonostylus without spines and with numerous strong and long setae. Tegmen wider than high and trapezoid, laterally with strong S-shaped curve, upper half very membranous, in middle with two sclerotized horizontal bars. Aedeagus short and very weakly sclerotized. Body length: 1.8–2.8 mm . Female . Undescribed. Recorded from Europe in some faunistic publications ( Metzner & Menzel 1996 ; Menzel et al . 2006 ). Material examined . KOREA : Gyeunggi-do, Suwon-si, Gwonseon-gu, Seodun-dong, Mt. Yeogi, Malaise trap, 17.vii.1995 , leg. J. Choi ( 4♂ ); Gyeunggi-do, Namyangju-si, Choan-myeon, Sonchon-ri, Mt. Ungil, 99 m a.s.l., Malaise trap, 26.vi–16.vii.2009 , leg. J. Lim ( 1♂ ). Habitats . Adult specimens have been collected in woodland, open montane habitats, heath land, moorland, wetlands (including fens, mires, water meadows, sedge beds and riverside habitats), unimproved calcareous grassland, and gardens. Larvae have been found in compost and been reared from dung ( Menzel et al . 2006 ). Distribution . New to Korea . Previously recorded from Austria , Central Asia, Czech Republic , Denmark , Finland , France , Germany , Great Britain , Iceland , Italy , Romania , Russia (Far East), Sweden , and Switzerland ( Metzner & Menzel 1996 ; Vilkamaa & Hippa 2005 ). Remarks . Cratyna vagabunda is widely distributed in the Palaearctic region. Korean specimens are smaller than Swedish specimens. This species is easily recognized by its long and strong sabre-like tooth on the gonostylus.
