Vol 94

Faunistic and taxonomic notes on the Oriental and East Palearctic species of Canthydrus SHARP, 1882 (Coleoptera: Noteridae) are provided. Fifteen species are recognised. All the species are analysed, and illustrations of habitus and male genitalia are provided. Canthydrus proximus SHARP, 1882 is redescribed and illustrated for the first time. The male genitalia of Canthydrus haagi (WEHNCKE, 1876) are also described and illustrated here for the first time. Canthydrus morsbachi WEHNCKE, 1876 is here confirmed as a valid species, very close to C. luctuosus (AUBÉ, 1838), together with which it shares a similar distribution in India and Sri Lanka, although it was described from Vietnam, where it was never collected again. New records are provided for C. birmanicus GUIGNOT, 1956 (Laos, Thailand), C. flavus (MOTSCHULSKY, 1855) (Laos, Malaysia), C. haagi (WEHNCKE, 1876) (Cambodia, Laos, Malaysia, Vietnam), C. luctuosus (Nepal), C. nitidulus SHARP, 1882 (China: Guangxi), C. po- litus (SHARP, 1873) (China: Macao, Vietnam), C. ritsemae (RÉGIMBART, 1880) (Brunei, Cambodia, Laos), and C. rocchii WEWALKA, 1992 (India, Laos, Thailand). The presence of C. flavus in India is yet to be confirmed; the record for Manipur published by VAZIRANI (1969a) must be attributed to C. rocchii. Doubtful records, which could be attributed to mislabeling, are here reported for C. luc- tuosus (Thailand), C. flammulatus SHARP, 1882, C. flavus and C. proximus (West Papua). New synonymies: Canthydrus antonellae TOLEDO, 2003 syn.n. = Canthydrus rocchii WEWALKA, 1992; Canthydrus festivus RÉGIMBART, 1888 syn.n. = Canthydrus laetabilis (WALKER, 1858); Hydrocanthus weisei WEHNCKE, 1876 syn.n. = Canthydrus luctuosus (AUBÉ, 1838); Canthydrus pseudomorsbachi VAZIRANI, 1969 syn.n. = C. luctuosus (AUBÉ, 1838). Lectotypes are designated for Canthydrus festivus RÉGIMBART, 1888, Canthydrus sexpunctatus SHARP, 1882 and Hydrocanthus luctuosus AUBÉ, 1838. For two taxa, Canthydrus bifasciatus RÉGIMBART, 1889 and C. testaceus (BOHEMAN, 1858), it was not possible to access the type material and their status remains obscure. A new diagnosis of the genus is given, pointing out the importance of the morphology of the aedeagus. The recent record of the Neotropical Hydrocanthus guignoti YOUNG, 1958 for India (Manipur) (DEVI et al. 2013, 2016) is based on a misidentification of Canthydrus rocchii.

Ochthebius (Cobalius) neptunus sp.n. (Coleoptera: Hydraenidae: Ochthebiinae) and Carpelimus (Tro- gophloeus) sulcitanus sp.n. (Coleoptera: Staphylinidae: Oxytelinae) are described. So far, both species are known only from cracks in the rocky shores on the northwestern shore of Sant’Antioco Island (SW of Sardinia, Italy).

A new species of the genus Habrocerus ERICHSON, 1839 (Coleoptera: Staphylinidae: Habrocerinae) is described: Habrocerus shan (Myanmar). The genital segment and male copulatory organ are illustrated.

Additional faunistic records are presented for the genus Eucibdelus KRAATZ, 1859 (Coleoptera: Staphylinidae: Staphylininae). One new species, E. gratoides, is described from India. Eucibdelus bhutanicus COIFFAIT, 1977 is removed from synonymy with E. gracilis KRAATZ, 1859. Eucibdelus quadricallosus BERNHAUER, 1916 is transferred to the genus Rhynchocheilus SHARP, 1889.

A new species of Shaverdolena SCHILLHAMMER, 2005 and three new species of Hybridolinus SCHILLHAMMER, 1998 (Coleoptera: Staphylinidae: Staphylininae) are described: Shaverdolena kubani (Laos), Hybridolinus assingi, H. ailaoshanus (both China: Yunnan) and H. mauson (Vietnam). Addit- ional locality data for H. similis SCHILLHAMMER, 1998 and H. meilishanus SCHILLHAMMER, 2008 as well as two other unnamed species are given. The male copulatory organs of all new species are illustrated and color photographs of their habitus are given. The key to the species of Hybridolinus is updated.

New synonyms in the genus Philonthus STEPHENS, 1832 (Coleoptera: Staphylinidae: Staphylininae) are presented. Philonthus tarsalis SMETANA, 1963 and P. nakanei SAWADA, 1965 are synonymized with P. aokii DVOŘÁK, 1958, P. numata DVOŘÁK, 1958 with P. eidmannianus SCHEERPELTZ, 1929, P. azabuensis DVOŘÁK, 1958 and P. yokohamus DVOŘÁK, 1958 with P. chujoi DVOŘÁK, 1958.

Stenus vitzliputzli sp.n. (Coleoptera: Staphylinidae: Steninae) is described from Mexico (Veracruz). It belongs to the S. hostilis species group and is very similar to S. baranowskii PUTHZ, 2001.

A new species of the genus Scirtes ILLIGER, 1807 (Coleoptera: Scirtidae), S. yoshitomii sp.n., is des- cribed from Hong Kong (China). It belongs to the Scirtes tigmanensis species group and is compared with the other three species of this group. Reference is made to the peculiar distribution of the species group.

The Oriental genus Aesobia JÄCH, 1982 (Coleoptera: Elmidae) is revised. The male of the type species, A. pygmaea JÄCH, 1982, is described for the first time. Three new species, A. kachinensis sp.n. (Myanmar), A. laosensis sp.n. (Laos), and A. kodadai sp.n. (Malaysia), are described. The genus is recorded from Malaysia and Myanmar for the first time. Most of the specimens of Aesobia collected so far, are brachypterous.

The Central Asian taxa of Stenelmis DUFOUR, 1835 (Coleoptera: Elmidae) are reviewed faunistically and taxonomically. Stenelmis aria JANSSENS, 1961 syn.n. is synonymized with S. fursovi ZAITZEV, 1951, and S. nematodes JANSSENS, 1959 syn.n. is synonymized with S. peropaca REITTER, 1907 stat.rev., which is elevated to species rank due to the distinctive structure of the elytral surface. A lectotype is designated for S. subtilis ZAITZEV, 1951. New confirmed country records: S. subtilis (Kazakhstan, Uzbekistan); S. koreana SATÔ, 1978 (China, Xinjiang, based on a sequence stored in BOLD). The true positions of the type localities of two species, which had been erroneously mislocated in the original descriptions, are clarified: S. fursovi (corrected from Tajikistan to Uzbekistan) and S. subtilis (corrected from Kazakhstan to Kyrgyzstan). Morphological characters, the allopatric distribution, as well as sequences of the standard DNA-barcoding COI gene region corroborate the specific distinctness of S. puberula REITTER, 1887 and S. subtilis. Habitus photographs of S. fursovi, S. peropaca and S. subtilis (including that of a living specimen), and illustrations of the ventrite VI, the aedeagus and the ovipositor of S. fursovi and the aedeagus of S. subtilis are provided for the first time. All known localities of the species of Stenelmis in Central Asia are shown on a map.

A new species of the genus Limnius ILLIGER, 1802 (Coleoptera: Elmidae), L. balcanicus JÄCH & BROJER sp.n., is described from Bosnia and Herzegovina, North Macedonia, Greece, and Bulgaria. The new species is sister to the allopatric L. colchicus DELÈVE, 1963 from Turkey, Georgia and Armenia. The latter is here recorded from seven Turkish provinces for the first time (Kastamonu, Amasya, Ordu, Rize, Erzurum, Artvin, Kars). The DNA barcode sequence for L. balcanicus, photographs of the habitus and the aedeagus, as well as a distribution map of both species are provided. For comparison, a habitus photograph of a syntype of Limnius rambouseki (MAŘAN, 1939) [= L. perrisi (DUFOUR, 1843)], described from North Macedonia, is also included.

Heterlimnius satoi (Coleoptera: Elmidae) is described from Russia (Far East) and China (Jilin). It is the second Palearctic member of the H. quadrimaculatus species group.

A new species of the genus Resachus DELÈVE, 1968 (Coleoptera: Limnichidae: Limnichinae) is described from Gabon: R. bilardoi sp.n. The new species is characterized by the head lacking the two oblique frontal sulci and by the morphology of the aedeagus (apex of parameres fused, truncate, and abruptly narrowed, with two short distal projections). The habitus and morphological details of diagnostic importance are illustrated by photographs. A distribution map of all known species of the genus is provided.

A new species of Heteroceridae, Augyles bendai SKALICKY sp.n. (Coleoptera: Heteroceridae), is described from Bangladesh. An annotated checklist of the Heteroceridae from Bangladesh is provided. Augyles ivojenisi (MASCAGNI, 1995), A. kubani SKALICKÝ, 2004, A. modicus MILLER, 1995, A. riedeli SKALICKÝ, 2003, A. weigeli SKALICKÝ, 2003 and Micilus minutissimus (SAHLBERG, 1900) are reported from Bangladesh for the first time.

The Heteroceridae hitherto recorded from Bhutan and Tibet are critically reviewed; six species pur- portedly collected by the insect dealer Jingke Li in Bhutan (Thrumshingla) (published by SKALICKÝ 2020) and two species allegedly collected in Tibet (published by JÄCH et al. 2012) are here removed from the fauna of Bhutan and Tibet. In fact, there is currently no evidence for the occurrence of the family Heteroceridae in Tibet. Augyles luciae (MASCAGNI, 1993) is here deleted from the fauna of the Palearctic Region.

Larvae embedded in Cretaceous amber were presented in a recent study on Haliplidae (LINHART et al. 2023). However, these fossil immature stages do not belong to this family and not to the suborder Adephaga. Instead they are here attributed to the polyphagan tenebrionoid Scraptiidae (subfamily Scraptiinae) based on the conspicuous unpaired club-shaped and apically rounded terminal abdominal process. It is recommended that investigations on fossil larvae should be undertaken with adequate techniques and expert knowledge of the group(s) in question.

The second edition of the Catalogue of Palaearctic Coleoptera, Vol. 6/2 (Chrysomeloidea II), edited by BEZDĚK & SEKERKA (2024), contains many corrections and additions to the first edition (LÖBL & SMETANA 2010). The present article deals with the chapter on the subfamily Donaciinae KIRBY, 1837, which was published in part 1 of Vol. 6/2 (GEISER 2024: 206–216) and provides explanations for some of the corrections and additions, especially those, which require more detailed treatment and therefore could not be printed in the second edition of the catalogue itself.

The second edition of the catalogue includes 91 Palaearctic species/subspecies of Donaciinae, eight fewer than in the first edition. Many changes in the genus Donacia FABRICIUS, 1775 were already published by GEISER & JÄCH (2021), but the number of species/subspecies has increased from 68 to 69, because D. kweilina CHEN, 1966 has been found to be species propria. Macroplea SAMOUELLE, 1819 now includes six instead of five species: two newly described species were added (M. huaxensis LOU & LIANG, 2011, M. ranina LOU & YU, 2011), and M. skomorohovi MEDVEDEV, 2006 is now regarded as a synonym of M. japana (JACOBY, 1885). The number of species in the genus Plateumaris THOMSON, 1859 has been reduced from 16 to 10 (GEISER 2023).

Additional and corrected faunistic records are also provided herein, based on recent literature data and on numerous museum specimens examined by the author. The data concerning the differences in the country records in the second edition of the catalogue, compared with the first edition, are listed here completely for Macroplea and Sominella JACOBSON, 1908. For Donacia, only the records which were not mentioned in GEISER & JÄCH (2021) are provided herein. All changes concerning faunistic data on Plateumaris were published in GEISER (2023). The data for Donaciasta FAIRMAIRE, 1901 and Neo- haemonia SZÉKESSY, 1941 did not change in the second edition of the catalogue.

During the printing process of the second edition of the catalogue, some additional data were acquired, which could not be included in the new edition: Donacia antiqua KUNZE, 1818 could not be confirmed for the Central Territory of Russia, D. vulgaris (ZSCHACH, 1788) was found to occur in Israel, and Macroplea mutica (FABRICIUS, 1792) has been confirmed for West Siberia.

Two species of Argoptochus WEISE, 1883 (Coleoptera: Curculionidae: Entiminae: Phyllobiini) from Albania, A. skodai sp.n. and A. valamarensis sp.n., are described and illustrated.

Contribution to the knowledge of the beetle fauna of the Lainzer Tiergarten. The Lainzer Tiergarten, a former imperial hunting ground, is a nature reserve largely located in the Federal State of Vienna (Austria). It is well known as a refugium for an endangered saproxylic beetle fauna. The seminatural forests shelter an exceptionally well conserved assemblage of species, which is unique for Central Europe. This article contributes to enhance the knowledge of this species assemblage. The data presented herein are based on numerous excursions carried out over a period of many years. The dataset covers about 10,000 specimens, which belong to 70 families and 901 species. Of these, 613 are regarded as saproxylic. Of the 69 primeval forest relict beetle species known from the area so far (Kahlen & Eckelt, unpubl.), we were able to detect 54 during our survey. With a total of 225 species, the rove beetles (Staphylinidae) were found to be the most speciose beetle family.
