FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK LV 1994 p. 19-20 A new Ceritaxa species from Hungary (Coleoptera: Staphylinidae) L. Ádám A new Ceritaxa species from Hungary (Coleoptera: Staphylinidae). - Ceritaxa alluvialis sp. n. is described from Hungary. Ceritaxa alluvialis sp. n. In general appearance similar to the other Ceritaxa species. Body somewhat flattened, finely and isodiametrically, rather indistinctly reticulated, weakly, greasily shining; reddish brown or brownish red in colour, ventral side more or less fuliginous, head and abdominal segments V-VII pitch-black or dark reddish brown, antennae also fuliginous but segments I—III paler. Head rounded quadrangular, subequal in length and width, finely and densely but rather indistinctly reticulated; punctuation dense, somewhat obsolete. Eyes convex, moderately prominent, a little longer than temple. Temples not bordered over their whole length. Antennae moderately long, relatively slender, barely fusiform. Antennái segment III a little longer than segment II; segment IV barely transverse, shorter than segment III; segments V-X moderately transverse, 1.5-1.75 times wider than long; segment XI large, a little longer than segments IX and X combined. Pronotum transverse quadrangular, 1.4-1.5 times wider than long, widest near posterior angles, arcuately narrowing anteriorly; basal margin arched; posterior angles rounded, obtuse-angled. Reticulation of pronotum similar to that of head; punctuation fine and dense, finely asperate. Hairs of pronotum directed rearwards at longitudinal midline and directed obliquely rearwards and toward lateral margin elsewhere. Inclined lateral margin of pronotum visible in lateral aspect. Elytra approximately parallel-sided, longer than pronotum; suture as long as pronotum. Reticulation and punctuation of elytra as those of pronotum. Posterior margin of elytra almost straight; outer posterior angles weakly emarginate. Abdomen approximately parallel-sided; tergites finely and densely, rather indistinctly reticulated; punctuation fine and indistinctly asperate; pubescence fine and rather dense. Abdominal tergites III-V with a transversal impression at base. Posterior margin of tergite VII narrowly bordered by a pellicle. Posterior margin of tergite VIII dentate, minor middle tooth pointed (Fig. 1) or blunt; posterior margin of sternite VIII rounded. Legs moderately long; tarsal formula: 4, 5, 5. Male genitalia: Figs 2-3. Length: 3.3-3.5 mm. Holotype (male): [Hung., Borsod-Abaúj-Zemplén m.], Révleányvár, Motolla, [talajcsapdázás (pitfall trapping)], 1993. VII. IL, Leg.: Hegyessy [G.].
