The nitidulidae and kateretidae (coleoptera: Cucujoidea) of Sicily: Recent records and updated checklist
No full textThis paper compiles an updated checklist of Sicilian species of Nitidulidae and Kateretidae from historical bibliographical data, and new Sicilian material collected by the first author and several other Italian and European entomologists in the last few decades. The paper is completed with an updated checklist of the species so far recorded from the island, including those based on unpublished data or extracted from recently examined material. A total of 88 species are reported (81 Nitidulidae and 7 Kateretidae). The new records for the Island include 10 Nitidulidae and 1 undescribed Kateretidae, and the neotropical Colopterus abdominalis (Erichson, 1843) is first recorded for Europe. The presence in SE Sicily of the invasive beehive pest Aethina tumida Murray, 1867, recently introduced to Calabria (Summer 2014), is also confirmed. Eight species, previously doubtfully recorded for Sicily, are to be excluded from the Sicilian fauna. c 2014 by the Author (s) - licensee Accademia Peloritana dei Pericolanti (Messina Italy)
First Maltese record of Stephanopachys quadricollis (Marseul, 1879) (Coleoptera, Bostrichidae)
Full text linkThree specimens of Stephanopachys quadricollis (Marseul, 1878) were recently found in Malta in UV light
traps and represent the first record of this species for this country. Although S. quadricollis is native to
the Mediterranean basin, it is not yet clear if these Maltese records are due to a natural population or to
an interception. Distributional, nomenclatural and biological data on this species are summarized, and a
new synonymy is established: Stephanopachys quadricollis (Marseul, 1879) = Stephanopachys quadraticollis

Struttura ed evoluzione della Regione di Controllo del DNA mitocondriale nel genere Meligethes (Coleoptera, Nitidulidae)
No full textUnderestimated diversity: Cryptic species and phylogenetic relationships in the subgenus Cobalius (Coleoptera: Hydraenidae) from marine rockpools
Full text linkMarine rockpools are isolated patches of habitat in the supratidal environment (the so-called splash zone), at the transition between sea and land, found along the rocky shores worldwide and characterized by harsh conditions for life. Nonetheless, few specialized invertebrates successfully colonized this peculiar environment. Among them several members of the water beetles Ochthebius Leach, 1815, subgenus Cobalius Rey (1886), which are found almost exclusively in supratidal and upper-most intertidal marine rockpools from the eastern Atlantic Ocean (Cape Verde, Canary Islands and Morocco, Madeira, Azores) throughout the whole Mediterranean basin. The subgenus Cobalius before 2020 was considered to include ten valid species, based on morphological differences. In late 2020, four additional new species were described. However, recent molecular phylogenetic studies have uncovered further cryptic diversity suggesting the presence of multiple undetected species within this group, highlighting that the species boundaries remain unclear and systematics and taxonomy are in need of revision. In this study we provide a molecular phylogeny based on DNA sequence data from mitochondrial and nuclear genes obtained from ten described species belonging to the subgenus Cobalius, and extensive taxon sampling, in order to better understand the phylogenetic relationships within this genus and to infer the biogeographic processes behind its diversification. We also used a molecular clock to define a time window for diversification of distinct clades within the subgenus, and explore aspects of its evolutionary history. Finally, we used three species delimitation methods (PTP, GMYC and ABGD) to clarify taxonomy and validate species boundaries. Our phylogenetic and biogeographic results identified sixteen independent lineages grouped in four main clades and the possible origin of Cobalius was estimated to be in the Early Miocene (~22 Mya) in W Mediterranean area. Moreover, species delimitation methods suggest there are between 16 and 24 putative species, most of them diverged during the Late Miocene, Pliocene and Pleistocene (6.0–0.11 Mya)
Four new species of Meligethes Stephens from China and additional data on other species of the genus (Coleoptera: Nitidulidae: Meligethinae)
No full textFour new species of Meligethes Stephens, 1830, M. (s.str.) macrofemoratus (Shaanxi, Ningxia), M. (s.str.) yak (NW Sichuan), M. (s.str.) auropilosus (Tibet) and M. (Odontogethes) aurorugosus (Tibet) spp. nov., are described and illustrated from China. Diagnostic characters distinguishing these new species from closely related taxa are discussed. The previously unknown male of Meligethes (s.str.) aureolineatus Audisio, Sabatelli & Jelínek, 2015 from Sichuan and the previously unknown female of M. (Odontogethes) scrobescens Chen, Lin, Huang & Yang, 2015 from Sichuan are also described. Additional data are also presented on the geographic distribution and life history of other Chinese Meligethes species
Description of the larva of Ochthebius capicola (Coleoptera: Hydraenidae) from marine rockpools of South Africa
No full textLarval instars II and III of Ochthebius (Ochthebius) capicola (Péringuey 1892) from South Africa are described and illustrated
by SEM, including a detailed analysis of their chaetotaxy and porotaxy. Specimens used in this study were collected
with adults of the same species in marine rockpools. The larval morphology of O. capicola is compared to that of other
members of the same genus occurring in this habitat, contributing to the current taxonomic and phylogenetic debate on
the intrageneric taxonomy of Ochthebiinae

No full textTaxonomic variation in levels of endemism: a case study of Italian tenebrionid beetles
No full text1. Levels of endemism are usually expressed as percentage of endemics among all species recorded in a given area. Endemism levels also vary among taxa, yet inter-taxon variation in endemism levels has received much less attention. 2. We used the Italian tenebrionids to investigate how endemism levels vary among different but related lineages. We evaluated endemism variations among taxonomic levels both as a percentage of endemics to the number of species included in a given taxon (i.e., the tendency of a taxon to produce endemics) and as a percentage to the total number of species (i.e., the importance of that taxon to the overall endemic component). We also considered the residuals of regression lines of endemics against non-endemics. We tested the influence of phylogenetic position, lifestyle and body size on the percentage of endemics within genera. 3. Use of percentages and residuals gave similar outcomes. Pimeliinae were the subfamily with the highest level of endemism. Erodiini, Pimeliini, Tentyriini, Asidini, Opatrini and Pedinini were among the tribes with the highest endemism levels. Asida, Pimelia, Tentyria and Opatrum were the genera with the highest levels of endemism. 4. Phylogenetic position and body size affected significantly endemism levels, with genera including larger species being also those with higher endemism, whereas lifestyle was not significant. This suggests that endemism in the Italian tenebrionid beetles is phylogenetically constrained and that lines including larger species (which are possibly less subject to passive dispersal) tend to be richer in endemics, independently from their lifestyle
