Fragmenta Entomologica 2019-06-16T01:47:05+02:00 Emanuela Fusinato Open Journal Systems <p><strong>Fragmenta entomologica</strong> (FE) was founded in 1950 by the lepidopterist Federico Hartig (1900-1980), at that time responsible of the Italian National Institute of Entomology. FE is now property of the Sapienza University of Rome, Italy (Department of Biology and Biotechnologies “C. Darwin”), and represents the scientific journal of the Zoological Museum, Sapienza University Museum Centre.<br> <strong>Fragmenta entomologica</strong> is devoted to publishing high-quality papers dealing with Arthropod biodiversity. It publishes research articles, short scientific notes, reviews articles, comments and editorials. The core scope of the journal includes Taxonomy, Systematics, Molecular phylogeny, Morphology, Paleontology, Biodiversity, Biogeography, Evolutionary biology, Conservation biology, Ecology, Ethology, and Applied Entomology, and embraces all terrestrial, freshwater, and brackish water Arthropods.</p> <p>This journal does not apply charge for publication to Authors as it is supported by institutional funds.</p> Entomological knowledge in Madagascar by GBIF datasets: estimates on the coverage and possible biases (Insecta) 2019-06-16T01:47:05+02:00 Mattia Iannella Paola D'Alessandro Maurizio Biondi <p>Although Madagascar is one of the world’s most important biodiversity hotspots, the knowledge of its faunistic diversity is still incomplete, notwithstanding many field campaigns were organized since the 17th century until nowadays, leading to a huge number of vertebrate and invertebrate records. In this contribution, taking into consideration the geographic distribution by a GBIF dataset including 286,764 records referred to nine insect orders (Coleoptera, Diptera, Hemiptera, Hymenoptera, Lepidoptera, Neuroptera, Odonata, Orthoptera, Trichoptera), we tried to supply some observations on the spatial distribution and to point out some possible biases in the entomological knowledge of Madagascar. Hymenoptera, Coleoptera and Diptera were the most represented orders in the dataset, respectively. Some orders show many “coupled” sampling, with peaks of shared sampled localities between Diptera with Hymenoptera (98.07%) and Hemiptera with Coleoptera (64.21%). Considering the geographic location and the extension of the vegetation macrogroups in Madagascar, the entomological data result unevenly distributed. Current Protected Areas’ (PAs) network covers about the 70% of the total of the collecting localities for the nine insect orders considered, even though some, such as Trichoptera, Odonata, and Neuroptera seem significantly less protected than others. However, the possible new PAs planned for Madagascar could greatly increase in the future the protection level for all 9 insect orders analyzed, especially for Neuroptera, Odonata and Lepidoptera. A percentage of 82.3% of the whole sampling localities falls inside the PAs themselves or within 1000 m from their borders. A similar pattern is observed for the road network: the 62.9% of the localities fall at least at 1000 m from a road, with no sampling localities observed further than 10 km from a road; statistically significant clusters were observed in evaluating these biases, coinciding with major towns or PAs.</p> 2019-05-31T00:00:00+02:00 ##submission.copyrightStatement## Revision of the genus Opisthozemius Kolbe, 1916, with description of a new species and designation of a new genus (Coleoptera: Brentidae, Cyphagoginae) 2019-06-16T01:47:04+02:00 Eylon Orbach Luca Bartolozzi <p>The Afrotropical genus <em>Opisthozemius</em> Kolbe, 1916 is revised. The genus now includes four species, one of which is described as new: <em>Opisthozemius naamae</em> sp. nov., from Tanzania and Zambia. <em>Opisthozemius sulcithorax</em> Damoiseau, 1967, from Java, is removed from the genus <em>Opisthozemius</em> and included in <em>Euparagogus</em> gen. nov. <em>Opisthozemius honestus</em> is placed in synonymy with <em>Opisthozemius vittatus</em> (new synonymy). A key for the identification of the species of <em>Opisthozemius</em> and some distributional data are also given. <em>O. appendiculatus</em> is quoted for the first time from Ghana; <em>O. vittatus</em> for the first time from Central African Republic, Ghana and Uganda.</p> 2019-05-31T00:00:00+02:00 ##submission.copyrightStatement## Cryptic diversity within the Anisoneura aluco-group (Lepidoptera: Erebidae) 2019-06-16T01:47:03+02:00 Alberto Zilli Rob de Vos <p>The <em>aluco-group</em> of the Indo-Australian genus <em>Anisoneura</em> is revised with characterisation of its component species and updating of their distribution. Types of all but one nominal taxa of the group are illustrated. The concept of <em>Anisoneura zeuzeroides</em> Guenée, 1852 is restricted to sole populations from Western New Guinea, while Moluccan (including Kei Islands’) populations previously ascribed to this nominal taxon are distinguished as <em>Anisoneura sphingoides</em> C. Felder, 1861 <strong>stat. rev.</strong> (= <em>Anisoneura depressa</em> Hulstaert, 1924, syn. nov.), and those from Eastern New Guinea are re-evaluated as <em>Anisoneura papuana</em> Hampson, 1913 <strong>stat. rev.</strong> The unusual circumstances of the scarce divergence in genitalia characters between species looking externally different (either sphingoides or zeuzeroides vs aluco) and <em>vice versa</em>, that is species almost indistinguishable in habitus albeit strongly differentiated in genitalia (either <em>sphingoides</em> or <em>zeuzeroides vs papuana),</em> is stressed. Lectotypes to <em>Anisoneura hypocyana</em> Guenée, 1852 and <em>Anisoneura sphingoides</em> C. Felder, 1861 are designated.</p> 2019-05-31T00:00:00+02:00 ##submission.copyrightStatement## Rhythmic abdominal pumping movements in praying Mantises (Insecta: Mantodea) 2019-06-16T01:47:02+02:00 Frederick R. Prete Aaron E. Schirmer Salim Patel Christina Carrion Greg M. Prete Bart van Alphen Gavin J. Svenson <p>We analyzed the rhythmic, cyclical dorsal-ventral abdominal pumping movements of nymphal and adult <em>Hierodula patellifera</em> (Audinet- Serville 1839), and adult <em>Stagmomantis carolina</em> (Johansson 1763), <em>Tenodera sinensis</em> (de Saussure 1871), <em>Miomantis paykullii</em> (Stål 1871), and <em>Sphodromantis lineola</em> (Burmeister 1838) using a combination of customized video analysis software and frame-by-frame video analyses. Despite the phylogenetic and ecological diversity of these species, we found fundamental similarities in the overall, intermittent patterns of their abdominal pumping movements. In adults of all species, intermittent bouts of abdominal pumping had median durations of 64-89 sec, and were separated by intervals with median durations of 10-25 sec. Bouts began with rhythmic upward abdominal deflections of progressively increasing amplitude and frequency which were superimposed on an overall, progressive abdominal elevation. Bouts ended with 1-4 very high amplitude, low frequency upward deflections after which the abdomen returned to its horizontal (resting) position. In <em>H. patellifera,</em> the overall adult pattern emerged gradually during larval development. Given the diversity of the species tested, our data suggest that intermittent abdominal pumping (which has been associated with respiratory behavior in insects) may be independent of ecological niche or acute environmental stressors in mantises. Instead, our data support the hypothesis that these apparently respiratory related, intermittent abdominal pumping movements are an emergent property of the mantis central nervous system organization.</p> 2019-05-31T00:00:00+02:00 ##submission.copyrightStatement## An updated checklist of the scarab beetle fauna of Asinara Island, Sardinia, Italy (Coleoptera: Trogidae, Geotrupidae, Scarabaeidae, Aphodiidae, Cetoniidae, Dynastidae, Hybosoridae) 2019-06-16T01:47:02+02:00 Julia T. Treitler Giuseppe M. Carpaneto Marco Dellacasa Jörn Buse <p>The island of Asinara, located in the northwest of Sardinia, is characterized by a large number of feral grazing mammals belonging to four herbivorous species (horse, donkey, mouflon, and goat) and an omnivorous one (wild boar). Hand-collections of scarabs in 2014 and the examination of unpublished records revealed the presence of five species new for Asinara (<em>Trox nodulosus, Ateuchetus laticollis, Sisyphus schaefferi, Caccobius schreberi</em> and <em>Cetonia carthami).</em> Based on all records (published and unpublished) we present a new checklist of the scarab beetle fauna of Asinara which increased from 30 to 43 species belonging to seven families: 2 Trogidae, 2 Geotrupidae, 13 Scarabaeidae, 19 Aphodiidae, 5 Cetoniidae, 1 Dynastidae, and 1 Hybosoridae</p> 2019-05-31T00:00:00+02:00 ##submission.copyrightStatement## Notes on the distribution and habitat of Ochthebius lobicollis Rey, 1885, a poorly known north-western Mediterranean coastal species (Coleoptera: Hydraenidae) 2019-06-16T01:47:01+02:00 Ignacio Ribera Carles Hernando <p><em>Ochthebius (Ochthebius) lobiccoastal habitatsollis</em> Rey, 1885 is recorded for the first time from the Iberian Peninsula (Girona) and the island of Corsica; new records are also given for the islands of Menorca and Sardinia. The species is known only from coastal habitats through the Gulf of Lion and the Ligurian and Balearic seas, typically living in rockpools of different salinity or small trickles or freshwater runoffs. Genetic data of the cytochrome oxidase 1 gene from Iberian, Menorcan and Sardinian specimens shows less than 1% divergence, suggesting lack of isolation between populations.</p> 2019-05-31T00:00:00+02:00 ##submission.copyrightStatement## Proposal for a time-based standard sampling method for the monitoring of Gomphus flavipes (Charpentier, 1825) and Ophiogomphus cecilia (Fourcroy, 1785) (Odonata: Gomphidae) 2019-06-16T01:47:00+02:00 Sönke Hardersen Ilaria Toni <p>Monitoring of conservation status is an obligation arising from Article 11 of the Habitats Directive for all species of community interest. However, the development of monitoring methods for invertebrate species has received relatively little attention. <em>Gomphus flavipes</em> (Charpentier, 1825) and <em>Ophiogomphus cecilia</em> (Fourcroy, 1785) are two dragonfly species, listed in the annexes of the Habitats Directive, which suffered severe declines in the last century and have since recovered. Methods for the monitoring of these two gomphids have been proposed, but these have not been extensively tested and no abundance classes have been proposed for the evaluation of the conservation status of these species. A time-based standard sampling method is proposed for both species and results from numerous sites in Lombardy, northern Italy, are presented. Applying the standard method revealed that it is common for rivers that high water levels preclude sampling of exuviae through the summer and it is better to allow for two seasons when planning the monitoring. A further result is the fact that it was not always possible to sample the same stretches as the dynamic nature of the rivers and fluctuations in water level lead to some river banks becoming unsuitable for sampling during some visits. In these cases the time-based approach was advantageous, as the method did not need to be modified in response to the original bank section becoming unsuitable.</p> 2019-05-31T00:00:00+02:00 ##submission.copyrightStatement## Habitat selection and morphology of Saga pedo (Pallas, 1771) in Alps (Susa Valley, Piedmont, NW Italy) (Insecta: Orthoptera, Tettigoniidae, Saginae) 2019-06-16T01:46:59+02:00 Luca Anselmo <p>This paper is a contribution to the knowledge of <em>Saga pedo</em> (Pallas, 1771), summarizing the results of a field study carried out on a population of the Italian W Alps. The peculiar eco-ethological traits of this species make its observation difficult in nature and overall also its biology is little known, especially in Italy. The habitat selection is outlined from 34 unpublished presence data, collected between 2016 and 2018. Moreover, some biometric traits are compared between adult individuals observed in two different and disjointed survey areas. The results show that the environments in which this species lives in Susa Valley should not be referred exclusively to xerothermic oases in strict sense. This species appears to be also associated, in fact, with xeric environments of agricultural origin, mostly abandoned vineyards. These land uses (especially viticulture) could have guaranteed the survival of <em>S. pedo</em> over time. The closure of these open areas by shrub and tree vegetation, constitutes an important threat factor. Phenology and morphology of this species in Susa Valley, seem do not differ from those reported for other European populations. However, from the biometric analysis some significant differences emerge (p&lt;0.05) among the individuals sampled in the two areas, that are difficult to interpret. The observation of imagoes, always combined with high densities of potential prey and sometimes grouped, suggests some hypotheses that it would be interesting to test, to learn more about the ethology and ecology of this enigmatic protected species.</p> 2019-05-31T00:00:00+02:00 ##submission.copyrightStatement## A critical review of the odonate fauna of Trentino: annotated check-list and new relevant data for Italy (Insecta: Odonata) 2019-06-16T01:46:55+02:00 Giacomo Assandri <p>By the first half of the Twentieth Century, the Odonate fauna of Trentino (Oriental Alps, Italy) was quite well known; subsequently, few surveys on dragonflies were carried out, resulting in a limited update of the knowledge on this taxon. The aim of this study is to provide a critical and annotated check-list of the Odonata of this province for the period from 1851 to 2018. This synthesis is based on a total of 3814 records obtained from the literature (955 records), revision of collections (1048 records), and unpublished recent data (1811 records). An updated and comprehensive Odonatological bibliography of the region is also provided. Overall, sixty-one species were confirmed to occur (or have occurred) in Trentino. These represent the 64% of the species recorded in Italy and the 43% of the species recorded in Europe. Presence of five additional species <em>(Ceriagrion tenellum, Coenagrion lunulatum,</em> <em>C. ornatum, Ophiogomphus cecilia,</em> and <em>Epitheca bimaculata</em>) should be considered doubtful for Trentino. Further two species <em>(Platycnemis latipes</em> and <em>Onychogomphus uncatus)</em> have to be excluded from the fauna of the study area. Fifty-four species were recorded also after 2000, whereas seven species were not confirmed after this year (<em>Lestes dryas, L. virens, L. barbarus, Sympecma paedisca, Coenagrion scitulum, Brachytron pratense</em>, and <em>Sympetrum flaveolum).</em> Several new records resulting from this study (referred to: <em>Erythromma najas, Aeshna subarctica, Aeshna caerulea, Aeshna grandis, Leucorrhinia pectoralis</em>) have a conservation or biogeographical relevance which transcends the borders of the study area, being noteworthy from an Italian or Alpine perspective and are thus commented in detail. Taxonomic notes on subspecies are also given when relevant.</p> 2019-05-31T13:27:31+02:00 ##submission.copyrightStatement## Geographical distribution and conservation status of the threatened saproxylic beetles Rhysodes sulcatus (Fabricius, 1787), Clinidium canaliculatum (O.G.
