New and little known Xantholinus Dejean, 1821 species from Hungary (Coleoptera, Staphylinidae) by L . T Ó T H , 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 report­ ed. 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 o f this subgenus are in all external characters extremely similar to each other and differ only i n 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. H e a d 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 s i m p l e . — A e d o e a g u s 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 contain­ ing only one strong curved spine ; distal portion furnished with 4 rows of shorter spines, at distal opening with 12-15 serrate scales (Fig. 1).—L e n g t h 7.6-9 mm.

Internal sac of the aedoeagus: 1 — Xantholinus (Meneidophallus) lichtneckerti sp. n., 2 = Xantholinus (Meneidophallus) magyaricus sp. n., 3 — Xantholinus (Meneidophallus) pseudobalaton sp. n. B i o n o m i c s : the collecting data (shore of the lake, near water, sifted debris under willowtrees, extracted from flood detritus) suggest that it is a stenotopic, hygrophilous, phytodetriticolous species. D i s t r i b u t i o n : Hungary, where it is possibly endemic. The species is named in honour of the famous Hungarian coleopterologist Ferenc Lichtneckert, who collected a part of the type series. Xantholinus (Meneidophallus) magyaricus sp. n. (Fig. 2) Elongate, slender, head shining black, thorax and elytra pitchy brown, abdomen black, antennae, mouthparts and legs rufotestaceous. H e a d ovoidal (46 : 33), a little widened behind (30 : 33) from posterior margin of very small and flat compound eyes to the widely rounded posterior angles, surface sparingly but deeply punctured except on midlongitudinal line of vertex, interstices covered by very fine transversal waves, shining.— A n t e n n a e longer than head, 2nd and 3rd segments equal in length, 4th-10th segments trans­ versal, gradually thickened apically last segment large, obconical, pointed obtuselly.—P r o n o t u m longer than wide (42 : 30), a little narrowed posteriorly (30 : 25), both of its dorsal rows with 8-10 large punctures, lateral rows with 6-7 punctures among some additional punctures which irregular seated mostly on anterior part, surface smooth and shining, covered only by fine microscopical punctures with trace of fine and nearly indistinct transversal waves at most on fore marginal parts.— E l y t r a as long as pronotum (42 : 42), a little dilated posteriorly (30 : 31), sides almost parallel, surface less shagreened than in closely related species, but no more shining, spare puncturation not larger but shallower.—A b d o m e n slender, a little widened behind to 6th (visible) segment, then narrowed apically. Surface with fine transversal waves and covered by scattered microscopical

punctures.—L e g s rather slender, segments of first tarsi simple.—A e d o e a g u s ovoidal. Proxi­ mal portion of internal sac with two rows of longer dark, curved spines, middle portion with two blind sack-shaped processes, the first sack set directly at beginning of the portion including two dark, curved „twin" spines, second sack situated at centre of this portion and including only one dark, curved spine, distal portion with 4 dense rows of shorter spines, near distal opening 10-12 serrate scales (Fig. 2).—L e n g t h 7.2-8.7 mm.

The species although similar to Xantholinus lichtneckerti sp. n., but differs from it by the presence of the " t w i n " spines and only a single isolated spine is on the middle portion of the internal sac. B i o n o m i c s : collecting data (shore of the lake, near water, sifted debries under willowtrees) suggest that it a stenotopic, hygrophilous, phytodetriticolous species. D i s t r i b u t i o n : Hungary, where is possibly endemic. The specific name magyaricus is derived from the word magyar, meaning Hungarian. Xantholinus (Meneidophallus) pseudobalaton sp. n. (Fig. 3) Elongate, slender, head dark brown or black, thorax dark, elytra pale pitchy-black, abdomen dark brown, antennae, mouthparts and legs reddish—rufotestaceous. H e a d ovoidal, longer than wide (40 : 32), from posterior margins of small and flat compound eyes to broadly rounded posterior angles slightly dilated (30 : 32). Rather shining, deeply and sparingly puncturated, surface covered with fine transversal waves except on vertex midlongitudinally and anteriomedially, where it is smooth and shining with only very fine microscopical punctures.— A n t e n n a e rather slender, longer than head, 2nd and 3rd segments equal in length, 4th to 10th transverse, gradually thickened apically, last segment obconical, pointed obtusely.—P r o n o t u m longer than broad (40 : 30), slightly narrowed behind (30 : 27) sides straight, both dorsal rows with 8-10 large punctures, lateral rows curved, fused distally with 6-8 punctures, some irregural additional punctures mostly on apical part, disc smooth and shining, covered only by very fine microscopical punctures, both marginal side with trace of very fine waves, especially near anterior angles.—E1 y t r a a little shorter than pronotum (38 :40), slightly dilated posteriorly (28 : 32), surface shagreened among covered microscopical punctures and shallow, large scattered punctures.—A b d o m e n slender, a little widened behind of the 6th (visible) segment, then narrowed apically, surface covered by fine transversal waves, among sparingly puncturated.—L e g s rather slender, segments of the first tarsi simple.—A e d o e a g u s ovoidal. Proximal portion of internal sac with two rows of longer dark curved spines, middle portion on centre near opposite-situated two blind sack-shaped processes; both including one strong dark curved spine, different from Xantholinus (Meneidophallus) balaton BORDONI, 1972 in which the first posessing strong spine situated directly at beginning of this portion and only second with strong spine set on centre of this portion. Distal portion furnished with four dense rows of shorter spines at near distal opening with 12-15 serrate scales (Fig. 3).—L e n g t h : 7.1-8.8 mm. H o l o t y p e çf : Siófok (Umg.), Lichtneckert—without further indication.—P a r a t y p e ç f : Dombóvár, 1947. I I I . 10, árvíz, rostálva, leg. Gebhardt.—Types are deposited in the Hungarian Natural History Museum, Budapest. B i o n o m i c s : collecting data (flood debries, shifted) suggest that the species is hygrophilous and phytodetriticolous. D i s t r i b u t i o n : Hungary where it seems to be endemic. The species is very similar to Xantholinus (Meneidophallus) balaton BORDONI, 1972, but it can be separated from the latter by the build of its aedoeagus, especially the position of the large, dark curved spines on the middle portion o f the internal sac. The specific name is derived from Balaton—name the largest Hungarian lake—and "pseudo".

Xantholinus (Meneidophallus) schweigeri COIFFAIT, 1966 The species was described by COIFFAIT (1966) from Lake Abant near Bolu, North Anatolia, Turkey. From Austria: Bad Vöslau, Zurndorf and between Neusiedel and Weiden, the two last places situated very near to the western border of Hungary and listed by FRANZ (1966). Finely COIFFAIT (1972) recorded it from Austria, Bulgaria and Asia Minor in his monograph. Its occurrence in Hungary is verified by 2 specimens: Velencei-hegység, Pákozd, Bella-völgy, fűzfák töve rostálva, 1951. X. 9, legit Dr. Kaszab; Velencei-hegység, Sukoró, tópart, fűzfák töve rostálva, 1951. X I . 12, legit Dr. Kaszab. Considering its known localities and collecting data (shore of the lake, near water, sifted under willow-trees) it seems a hygrophilous, thermophilous, phytodetriticolous species. The occurrence of this rare southern element in the fauna of Hungary remarkable indeed. The two known Hungarian specimens are deposited in the collection of the Hungarian Natural History Museum in Budapest. The species is in all external characters extremely similar to Xantholinus (Meneidophal­ lus ) roubali COIFFAIT, 1956 and differs in its fine structure of the internal sac. Xantholinus (Meneidophallus) varhegyanus BORDONI, 1973 The species was described by Bordoni (1973) from Várhegy, Brassó, Transylvania. Its first occurrence within present borders of Hungary is indicated by only one çf specimen from the Kis­ kunság National Park (Kiskörös: Szücsi-erdő, mocsár, talajcsapda, 1978. IV. 26. and V I . 1. leg. Dr. Tóth L.). Its distribution is insufficient known yet, it seems that the species is endemic to the Carpathian Basin, presuming that its distribution is larger in Hungary than it is known presently. The clarification of this problem is highly desirable for a better understanding of our fauna, but it will be possible only after further collectings and investigations in the future. The bionomics of the species is unknown, only the collecting data (marshy forest, in soil trap) suggest that it is a hygrophil­ ous and paludicolous element. Xantholinus (Paraphallus) sublinearis COIFFAIT, 1969 The species was described from Beroia, Chantova, Macedonia, Greece. COIFFAIT (1972) recorded it from Greece and Bulgaria, Bordoni (1972) listed it fron\9 localities of North-Italy, JANÁK (1978) mentioned it from South-Moravia and South-Slovakia, Sturovo ( = Párkány), the latter locality being in the Carpathian Basin. The first occurrence of this species in Hungary was verified by 3 çf specimens. Their localities and collecting data are the following: 1. Budapest, Törökvész, 1940. X I . 3, coll. E. Csiki; 29. 2. Pinnye, 1917. IX. 29,coll.Dr. R. Streda; 3. Kiskunság National Park, Orgovány, szikes rét, talajcsapda (alkali meadow, in soil trap) 1978. V I . 22-IX. 21, leg. Hámoriné. The collecting data suggest that the species is stenotopic, thermophilous, partially halophilous and bound to the soil layer. It seems a rare and interesting Mediterranean element in the Hungarian fauna. The species can be separated from X. linearis OLIVIER, 1974, by the armature of the internal sac. Xantholinus (Xantholinus s. sir.) rhenanus COIFFAIT, 1962 The species was described from Bas-Rhin forêt de Haguenau, France. Subsequent publications listed it from Austria, Czechoslovakia, Denmark, France, Germany, Poland (LOHSE 1964, HORION 1965, SMETANA 1966, COIFFAIT 1972, SZUJECKI 1980). The first occurrence of this rare species in Hungary was verified by 3 çf specimens from the same locality : Velencei-tó, Sukoró, tópart, fűzfák töve rostálva, 1951. X I . 12, legit Dr. Kaszab. The collecting data (lake shore, sifted under willowtrees) suggest that the species is hygrophilous, phytodetriticolous and stenotopic. I presume its distribution is greater in Hungary than presently known. The species can be separated from X. longiventris HEER, 1839 by the armature of the internal sac. Xantholinus (Meneidophallus) dvoraki COIFFAIT, 1955 There are some specimens under this name in the collection of the Hungarian Natural History Museum, Budapest. I have found that they had been misidentified, the specimens belong to X. (Menei­ dophallus) roubali COIFFAIT, 1956. Unquestionably, X. dvoraki COIFFAIT, 1955 has been collected from the Carpathian Basin (Slovakia), but we have so far no specimens from within the present Hungarian borders. So the species has to be removed from the faunistic checklist of Hungary as a previous misidentification.

Xantholinus (Acanthophallus) azuganus REITTER, 1908 There are two specimens under this name in the collection of the Hungarian Natural History Museum, Budapest. I have found that their identification is also faulty, they belong to X. (Acanthophallus) laevigatus JACOBSEN, 1847 which is not common but widely distributed in Hungary. The prepared male genitalia were damaged and—in my humble opinion—this was the circumstance which led to the misidentification. X. azuganus REITTER lives in the Carpathian Basin, but only on the high mountains of Transylvania and in the Carpathians as a subalpine, alpine element with low ecological tolerance. The suitable habitats for this species absent in present-day Hungary so there is little likelihood of its occurrence within our present borders. The species has to be removed from our faunistical checklist as former misidentification.
