The Kateretidae and Nitidulidae of the Maltese Archipelago (Coleoptera)

Abstract

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.
