ANNALES HISTORICO-NATURALES MUSEI NATIONALIS HUNGARICI Tomus 77. Budapest, 1985 p. 173-177. New and little known Xantholinus Dejean, 1821 species from Hungary (Coleoptera, Staphylinidae) by L. TÓTH, Budapest Abstract

—Descriptions of Xantholinus lichtneckerti sp. n., X. magyaricus sp. n. and X. pseudobalaton sp. n. are given with 3 figures. The first occurrence of Xantholinus schweigeri COIFFAIT, X. rhenanus COIFFAIT, X. sublinearis COIFFAIT and X. varhegyanus BORDONI in Hungary are reported. Xantholinus dvoraki COIFFAIT and X. azuganus REITTER are removed from the faunistical checklist of Hungary. With 3 figures. During the identification of the Xantholininae collection from the Carpathian Basin of the Hungarian Natural History Museum, Budapest, three new Xantholinus species were found from Hungary. Each species belongs to the subgenus Meneidophallus BORDONI, 1972. The species of this subgenus are in all external characters extremely similar to each other and differ only in the fine structure of their aedoeagus. Hence the subgenus is based strictly on the characters of armature of the internal sac. Xantholinus (Meneidophallus) lichtneckerti sp. n. (Fig. 1) Moderately slender, head shining black, thorax dark and elytra pale pitchy-black, abdomen dark brown nearly black, antennae, mouthparts and legs rufotestaceous. Head longer than thorax (45 :40) and elytra (45 : 40), ovoidal, slightly dilated posteriorly (27 : 30), dorsal surface with moderately deep and scattered punctures, interstices covered with fine transversal waves except midlongitudinally and anteriomedially, where smooth and shining, covered only fine microscopical punctures.

—

A n t e n n a e elongatae, 2nd and 3rd segments equal in length, 4th-10th segments transverse, gradually thickened apically, last segment obconical, pointed obtuselly.

—

P r o n o t u m reversed trapesoidal, longer than wide (40 : 30) a little narrowed posteriorly, sides straight, both dorsal rows with 8-10 large punctures, both lateral rows with 6-7 punctures among the two rows on both side with numerous additional punctures anteriorly. Surface of pronotum at most with trace of very fine transverse waves between lateral margin and dorsal row on both sides, sometimes indistinct or entirely lackink, on the disc between dorsal rows always smooth and bright, covered only by very fine microscopical punctures.

—E 1 y t r a as long as pronotum, a little widened behind (26 : 30), surface shagreened among covered coarse punctures.

—

A b d o m e n slender, a little widened behind to the 6th (visible) segment, then suddenly narrowed apically. Surface of tergites with fine scattered puncturation, among moderately sharp, fine transverse waves.

—

L e g s moderately slender, segments of first tarsi simple.

—Aedoeagus ovoidal. Proximal portion of internal sac with two rows of longer dark curved spines, middle portion with three blind sackshaped processes. First sack including two dark curved „twin" spines second sack set centrally situated and including one strong curved spine, third sack set on end of middle portion, and containing only one strong curved spine ; distal portion furnished with 4 rows of shorter spines, at distal opening with 12-15 serrate scales (Fig. 1).—

Types are deposited in the Hungarian Natural History Museum, Budapest. The species can be separated from the others within the subgenus by the presence of the "twin" spines as well as the two isolated spines on the middle portion of the internal sac.
