New records of Hesperinidae and Bibionidae (Insecta, Diptera) from Croatia

Authors:

Abstract and Figures

We review the published records of Hesperinidae and Bibionidae (Diptera) from Croatia and add some new records based on recent, sporadic collecting in the country. The species Bibio handlirschi Duda, 1930 and Bibio reticulatus Loew, 1846 are recorded for the first time from Croatia. Notes are given on the taxonomy and bionomy of some of the species.

... Our study shows that dead wood is chosen by groups with a very different biology: obligate saproxylic species ( (Irmler et al. 1996, Podėninė 2003, Nielsen and Nielsen 2007, Ševčík 2010, Jakovlev 2011, Jakovlev 2012, Seeber et al. 2012, Podėnienė 2012, Skartveit et al. 2013, Imada 2020. Once again, this shows the importance of dead wood not only for typical saproxylic insects, but also for other forest-dwelling species that choose wood only as a random site of development. ...
... Bibio nigriventris and B. reticulatus (Bibionidae) mostly were reared from oak and small-leaved lime. Adults of B. reticulatus are common in woodlands, where they usually occur in large numbers (Skartveit et al. 2013). Their larvae develop in strongly decomposed friable wood, decaying wood roots or forest litter (Krivosheina 2006). ...

The aim of this study is to compile the species list of Bibionomorpha and Tipulomorpha flies associated with dead wood in Lithuania. Saproxylic nematocerans were studied from 2014 to 2020 in four protected areas and in five different tree species (Populus tremula, Quercus robur, Tilia cordata, Fraxinus excelsior and Alnus glutinosa) of the second stage of decay by using emergence traps. In total, 113 species were identified with Mycetophilidae, Sciaridae and Limoniidae being the most species-rich families. The compiled list of species emerging from dead wood in Lithuania is presented. Fourteen species were reared from dead wood for the first time.

Faunistics of Diptera were studied in the Arak region and suburb (Markazi province) and specimens were collected on crop and non-crop plants by a standard sweep net. Two species of the family Bibionidae were verified by Dr John Skartveit (Norway). Both species, which are considered occasional horticultural pests in Europe, are newly recorded for Markazi province.

Fossil bibionid flies in amber are quite rare, but a number of specimens have been found by Christel and Hans Werner HOFFEINS, they are described in the following. Also included are specimens from Museum d’ histoire naturelle, Neuchâtel, Switzerland. The following new taxa are established: Hesperinus electrus sp.n., Hesperinus hyalopterus sp.n., Hesperinus macroculatus sp.n., Penthetria integroneura sp.n., Penthetria montanaregis sp.n., Plecia brunnipennis sp.n., Plecia clavifemur sp.n., Plecia hoffeinsorum sp.n., Plecia tenuicornis sp.n., Bibiodes balticus sp.n., Bibiodes nanus sp.n., Dilophus palaeofebrilis sp.n., Dilophus crassicornis sp.n. and Dilophus succineus sp.n. Two specimens of Plecia prisca MEUNIER, 1899 were found and are briefly described. Additional specimens of Plecia, Bibio and Dilophus are briefly described but not given species names since too few characters are visible. Hesperinus immutabilis MELANDER, 1949 is transferred to the genus Penthetria. The genus Bibiodites COCKERELL, 1915 is synonymised with Bibiodes COQUILLETT, 1904. The genus Megeana MEUNIER, 1899 is transferred from Bibionidae to Empidoidea.

Here we present the methodology used for terrestrial biodiversity analysis and site selection in Phase B of the UNDP/GEF COAST project. The analysis was focused on the problem of biodiversity evaluation in four Croatian counties stretching from sea level to the highest mountain in Croatia. Data on habitats, vascular flora, and fauna (mammals, birds, reptiles, amphibians, butterflies, ground beetles, and underground invertebrates) were collected and analyzed for each of the four counties. Emphasis was given to the richness of endangered species and the rarity of endemic species. Based on the spatial analyses of habitat, fauna, and flora data, four to six areas were selected from each county and ranked according to their biodiversity importance. Overlap between areas important for richness and those important for rarity was highest for data on flora (65.5%) and lowest for data on fauna (16.7%). When different data sets were compared, the lowest overlap was between flora and fauna (17.1%) and largest between fauna and habitats (23.9%). Simultaneous overlap among all three data sets was found in just 6.5% of the overall selected areas. These results suggest that less specific data, with respect to taxa threat status, could better serve as surrogate data in estimating overall biodiversity. In summary, this analysis has demonstrated that Dalmatia is a region with a high overall biodiversity that is important in a broader European context.

Balkan Biodiversity is the first attempt to synthesise our current understanding of biodiversity in the great European hot spot. The conservation of biodiversity is one of today’s great ecological challenges but Balkan biodiversity is still poorly understood, in a region with complex physical geography and a long history of political conflict. The Balkans exhibit outstanding levels of endemism, particularly in caves and ancient lakes such as Ohrid; lying at the crossroads of Europe and Asia they are also renowned as a focus of Pleistocene glacial refugia. This volume unites a diverse group of international researchers for the first time. Its interdisciplinary approach gives a broad perspective on biodiversity at the level of the gene, species and ecosystem, including contributions on temporal change. Biological groups include plants, mammals, spiders and humans, cave-dwelling organisms, fish, aquatic invertebrates and algae. The book should be read by zoologists, botanists, speleobiologists, palaeoecologists, palaeolimnologists and environmental scientists.

ABSTRACT We studied species richness patterns of obligate subterranean (troglobiotic) beetles in the Dinaric karst of the western Balkans, using five grid sizes with cells of 80 × 80, 40 × 40, 20 × 20, 10 × 10, and 5 × 5 km. The same two hotspots could be recognized at all scales, although details differed. Differences in sampling intensity were not sufficient to explain these patterns. Correlations between number of species and number of sampled localities increased with increasing cell size. Additional species are expected to be found in the region, as indicated by jackknife 1, jackknife 2, Chao2, bootstrap, and incidence-based coverage (ICE) species richness estimators. All estimates increased with increasing cell size, except Chao2, with the lowest prediction at the intermediate 20 × 20 km cell size. Jackknife 2 and ICE gave highest estimates and jackknife 1 and bootstrap the lowest. Jackknife 1 and bootstrap estimates changed least with cell size, while the number of single cell species increased. In the highly endemic subterranean fauna with many rare species, bootstrap may be most appropriate to consider. Positive autocorrelation of species numbers was highest at 20 × 20 km scale, so we used this cell size for further analyses. At this scale we added 137 localities with less positional accuracy to 1572 previously considered, and increased 254 troglobiotic species considered to 276. Previously discovered hotspots and their positions did not change, except for a new species-rich cell which appeared in the south-eastern region. There are two centres of troglobiotic species richness in the Dinaric karst. The one in the north-west exhibited high species richness of Trechinae (Carabidae), while in the south-east, the Leptodirinae (Cholevidae) were much more diverse. These centres of species richness should serve as the starting point for establishing a conservation network of important subterranean areas in Dinaric karst.

The Mediterranean peninsulas contain much genetic and species diversity, which decreases toward higher latitudes in Europe. In considering how such diversity evolved, three areas of activity seem important – Paleogeology, Paleoclimatology, and Phylogeography. The complex collision of the African and European tectonic plates produced the very different peninsulas of Iberia, Italy, and the Balkans. The climate cooled from 50 Mya with increasingly severe ice ages over the last 2 My that repeatedly modified species distributions and hence species evolution. As well as many endemic species, genetic methods show the peninsulas to have distinct genotypes in many species, with various postglacial histories. Their mountainous topography appears important for the survival of species through the ice ages and previously. In Iberia, mountains are the focus for multiple refugia, producing several diverged genetic lineages. Italy shows more recent subdivision through multiple refugia, particularly in the south. The Balkans has many more endemics, but fewer phylogeographic studies than other peninsulas. Multiple refugia and a range of lineage ages indicate continuous divergence and speciation over many millions of years to the present. The peninsulas are important as refugia for the survival of species and engines of speciation.
