Atheta ( Philhygra ) palustris : Fenyes, 1920: 201; Yosii & Sawada, 1976: 29; Paśnik, 2001: 206; (as valid species). See Gusarov (2003), Smetana (2004) and Gouix & Klimaszewski (2007) for more synonymies. Description. Body length 2.2–2.9 mm. Body (Fig. 1 C) relatively narrow and elongate in dorsal aspect. Head almost black; antennae, pronotum and elytra dark brown, elytra paler than pronotum; abdominal tergites II–V dark brown and VI–VIII brownish black; legs yellowish brown. Head surface glossy, with fine punctation, distance between punctures 1–3 times longer than their diameter; head about as wide as long, widest at across eyes; eyes slightly prominent, about 1.25 times longer than tempora; antennomeres 4–5 slightly elongate, 6–10 about as long as wide, 11 about as long as preceding two combined (Fig. 4 A); labrum (Fig. 4 B) emarginate in anterior margin; asensillum relatively long; medial pseudopores absent, lateral pseudopores present in prementum. Pronotum transverse, approximately 1.2 times as wide as long, widest at apical third; pubescence in midline directed anteriorly; punctation finer than on head, distance between punctures 1–2 times longer than their diameter; metanotal scutum with one long setae and about 3–6 short setae on each side of midline; mesoventral process elongate and slightly pointed at apex, longer than isthmus; metaventral process little shorter than isthmus (Fig. 4 C). Elytron approximately 1.8 times as long as wide; postero-lateral margin nearly straight; flabellum composed of about 14 setae. Abdominal tergites glossy, with fine punctation, distance between punctures 0.5–1 times longer than their diameter; male tergite VIII (Fig. 4 D) with 4 macrosetae on each side of midline, posterior margin emarginate; male sternite VIII (Fig. 4 E) truncate in posterior margin, with conspicuously long marginal setae; female tergite VIII similar to male tergite VIII; posterior margin of female sternite VIII convex, more or less round, with moderately long marginal setae. Aedeagus as in Figs. 4 F–H. Material examined.
