The Kateretidae and Nitidulidae of the Maltese Archipelago (Coleoptera)

In the present work, a total of 3 Kateretidae and 26 Nitidulidae are recorded from the Maltese Islands. Of these, 14 Nitidulidae (Epuraea luteola, Epuraea ocularis, Carpophilus bifenestratus, Carpophilus marginellus, Carpophilus quadrisignatus, Carpophilus dimidiatus, Carpophilus nepos, Urophorus humeralis, Urophorus rubripennis, Nitidula carnaria, Omosita discoidea, Meligethes rotundicollis, Meligethes ruficornis, Cybocephalus rufifrons rufifrons) and 1 Kateretidae (Brachypterus curtulus) represents new records for the Maltese Islands. Of these both autochthonous and accidentally introduced but established species are present. The earlier citation of Cybocephalus politus may be due to a misidentification. Three further new records of Nitidulidae, Carpophilus opacus, Brachypeplus deyrollei and Brachypeplus rubidus were collected alive on logs originating from Tropical Africa and intended for the timber industry. So far, there were no local records of establishment of any of these three species. All species were assigned to four faunistic groups. These include introduced but non-established species, cosmopolitan species, species with confined distributions and species with small distribution ranges. The complete absence of other species whose host-plants are locally available and which have typical Mediterranean distribution was highlighted. From a zoogeographical perspective the species assemblages of Kateretidae and Nitidulidae of Malta show strong affinities with those present in Italy.peer-reviewe

Two new Lamiogethes Audisio & Cline from China (Coleoptera: Nitidulidae, Meligethinae)

Two new species of the genus Lamiogethes Audisio & Cline, 2009are described from China (Sichuan): L.forcipenissp. n.,and L.con-vexistrigosussp. n., based on a series of recently collected specimens. The new species are both likely morphologically related to L.po-tanini (Kirejtshuk, 1979) from Sichuan and to L. conjungens (Grouvelle, 1910) from Yunnan. These new species clearly differ from their related taxa by details of the body shape and color, and the distinct shape of the male and female genitalia. Both new species are likely associated as larvae with a member of the genus PhlomoidesMoench (Lamiaceae)

A new species of Meligethes Stephens from China and additional data on members of the M. chinensis species-complex (Coleoptera: Nitidulidae, Meligethinae)

Meligethes (Odontogethes) inexpectatus sp. n. is described from China, Sichuan Province. The new species is based on a female specimen previously incorrectly referred to as Meligethes scrobescens Chen, Lin, Huang & Yang, 2015, which was recently described from a series of male specimens collected in the same area. Both species belong to the taxonomically difficult species-group related to M. chinensis Kirejtshuk, 1979, including a dozen closely related species distributed throughout Nepal and SW and Central China. The true female of Meligethes scrobescens is also described, based on recently collected material from China (Hubei and Chongqing), including a series of male and female specimens. Diagnostic characters distinguishing the new species from all other known members of the M. chinensis species-group and species-complex are discussed, and their overall range distribution are depicted. Additional data on geographic distribution and larval ecology of some of the closely related species are also reported

DAPSA GEMINA AUDISIO & DE BIASE, 1996, A NEW SPECIES OF THE EUROPEAN FAUNA (Coleoptera, Endomychidae)

During entomological research carried out in the Pontine Islands (central Italy, Latium, Latina province), Dapsa gemina Audisio & De Biase, 1996 (Coleoptera, Endomychidae), previously known only from coastal areas of NE Algeria, has been recorded in Italy and in Europe for the first time. This new record suggested the authors to shortly discuss the possible scenario of a relatively recent, late Pleistocene passive transportation of Dapsa gemina and of the related D. obscurissima Pic, 1904 (sharing a very similar disjunct geographic distribution) by marine drift of masses of vegetal debris from North Africa

Revision of the pollen beetle genus Meligethes (Coleoptera: Nitidulidae)

A taxonomic revision of members of the genus Meligethes Stephens, 1830 is carried out. Taxonomic and distributional notes are provided on fiftythree Meligethes species, mostly known from the Eastern Palearctic and marginally from the Western Palearctic and the Oriental Regions. Among these, twentythree new species of Meligethes are diagnosed, figured and described: M. argentithorax sp. n. (Central China: Shaanxi, Shanxi), M. aurantirugosus sp. n. (Nepal), M. aureolineatus sp. n. (Central China: Sichuan), M. aurifer sp. n. (Central China: Shaanxi, Shanxi), M. brassicogethoides sp. n. (SW China: Yunnan), M. clinei sp. n. (SW China: Yunnan), M. elytralis sp. n. (Central China: Sichuan), M. ferruginoides sp. n. (Central China: Sichuan), M. cinereoargenteus sp. n. (Central China: Sichuan), M. henan sp. n. (Central China: Henan), M. luteoornatus sp. n. (SW China: Yunnan), M. marmota sp. n. (Nepal), M. nivalis sp. n. (SW and central China: Xizang and Chongqing), M. martes sp. n. (Central China: Shaanxi, Shanxi, Sichuan), M. nigroaeneus sp. n. (SW China: Yunnan), M. occultus sp. n. (SW China: Yunnan), M. pseudochinensis sp. n. (Central China: Hubei), M. pseudopectoralis sp. n. (SW China: Yunan), M. schuelkei sp. n. (Central China: Sichuan, Shaanxi), M. simulator sp. n. (Central-N China: Shanxi), M. stenotarsus sp. n. (SW China: Yunnan, Xizang), M. tryznai sp. n. (SW China: Yunnan), and M. volkovichi sp. n. (SW China: Yunnan). Revaluations at specific rank from synonymy are introduced for Meligethes lutra Solsky 1860, and for M. melleus Grouvelle, 1908. Three new synonymies are established: Meligethes brevipilus Kirejtshuk, 1980 = M. auripilis Reitter, 1889 (syn. n.), Meligethes zakharenkoi Kirejtshuk, 2005 = M. shirakii Sadanari Hisamatsu, 1956 (syn. n.), and Meligethes shirozui Sadanari Hisamatsu, 1965 = M. wagneri Rebmann, 1956 (syn. n.). Complete redescriptions are given for Meligethes binotatus Grouvelle, 1894, M. castanescens Grouvelle, 1903, M. ferrugineus Reitter, 1873, and M. melleus Grouvelle, 1908. The male of Meligethes lloydi Easton, 1968, is described and figured for the first time. The female genitalia of Meligethes auricomus Rebmann, 1956, M. cinereus Jelínek, 1978, and M. griseus Jelínek, 1978 are described and figured for the first time. Available information on insect-host-plant relationships and ecology are summarized for each species; probably all are associated as larvae with flowers of Rosaceae, chiefly of members of the closely related genera Rosa L., Rubus L., Prunus L., and Crataegus Tourn. ex L. All treated species are grouped in two here revaluated subgenera (Meligethes s.str. and Odonthogethes Reitter, 1871), and tentatively grouped also in species-groups and (when necessary) species-complexes, based on their morphology

Epuraea imperialis (Reitter, 1877). New invasive species of Nitidulidae (Coleoptera) in Europe, with a checklist of sap beetles introduced to Europe and Mediterranean areas

Australian species Epuraea imperialis (Reitter, 1877), previously introduced to New Zealand, is recorded as a new invasive species from the Canary Islands, Continental Spain, Portugal, France, Belgium, and Italy. It is redescribed and figured, and its taxonomic position in the genus Epuraea Erichson, 1843 is discussed. A tentative checklist of sap beetles introduced to Europe and the Mediterranean areas is finally included

Molecular and morphological analyses confirm two new species of the Hydraena emarginata–saga clade (Coleoptera, Hydraenidae) from Spain and France

El documento auto-archivado en Digital.CSIC es el PRE-PRINT del autor. La versión definitiva se publicó posteriormente en Zootaxa 2760 : 29-38 (2011)Using morphological and molecular analyses, the existence of two undescribed species, H. diazi from north–eastern Spain and French Pyrenees, and H. fosterorum from north–central Spain is confirmed. These species are members of a European endemic complex of hydraenid beetles, the Hydraena emarginata–saga clade, belonging to the ”Haenydra“ lineage. The two new species are described and the geographic range of the widespread H. saga is revised.A visit of the first author to the NMW was supported by Synthesys (Application AT–TAF–53); the work of IR was funded by projects CGL2007–61665 and CGL2010–15755.Peer reviewe

Description of the unknown males of three Chinese Meligethes (Coleoptera: Nitidulidae, Meligethinae)

In this paper we present the description of male genitalia and additional information on taxonomy of three recently described and poorly known Chinese endemic members of the genus Meligethes Stephens, 1830, Meligethes (Odonthogethes) brassicogethoides Audisio, Sabatelli & Jelínek, 2015, M. (O.) inexpectatus Liu, Huang, Cline, Sabatelli & Audisio, 2017, and M. (O.) tricuspidatus Liu, Huang, Cline & Audisio, 2018

PITYOPHAGUS QUERCUS REITTER, 1877, A NEW SAPROXYLIC SAP BEETLE FOR THE ITALIAN FAUNA (Coleoptera, Nitidulidae)

During ecological investigations on saproxylic beetle communities of central Italy (Latium), at Bosco Polverino (a mixed evergreen/deciduous forest fragment dominated by cork oaks), and at Allumiere (a small fragment of beech forest surrounded by turkey oak stands), the authors found three specimens of Pityophagus quercus Reitter, 1877 (Coleoptera, Nitidulidae). These are the first known records of this species in Italy, and the first one in association with an evergreen oak, Quercus suber. This discovery led us to review both bionomical and faunistic data so far available on this exceedingly rare and poorly known species
