Changes in caddisflies community composition and distribution along 60 years timespan monitoring in Luxembourg https://contributions-to-entomology.arphahub.com/article/110329/ Contributions to Entomology 73(2): 279-288

DOI: 10.3897/contrib.entomol.73.e110329

Authors: Alain Dohet, Sarah Vray, Lionel L’Hoste

Abstract: In Luxembourg, caddisflies have been systematically collected since the early Sixties. Three periods of exhaustive sampling may be distinguished: the Sixties; 1994 to 2002; and a long period from 2007 to the present time in the frame of the Water Framework Directive. Bearing in mind the uneven sampling procedure across periods, we aim to document changes in community composition and distribution through time including the nature of these changes (e.g. gains and losses of species). We hypothesise different trends of species gains and losses for specialist species in comparison to generalist species. Therefore, we propose a method to identify specialist and generalist species in our dataset. Historical data (1961 to 1968) lack information on precise locations and abundance of specimen collected. Consequently, cell grids of original distribution maps are used to compare caddisfly community assemblages along the three monitoring periods. We assess the changes that occur on presence/absence data in specific groups of species (i.e. cold-adapted, warm-adapted specialists and generalist species). Temporal β-diversity results reveal that survey intervals for each monitoring period are dominated by species losses when the comparison is restricted to cold-adapted species. On the other hand, warm-adapted and generalist species are increasing from the Sixties period when compared to the two next periods (1994–2002 and 2007–2020). However, the comparison of the most recent periods reveals species losses even for the warm-adapted and generalist species. This complex picture of caddisflies species losses and gains in different ways through time, amongst river types and in response to different pressures, is discussed.

Hydraulic engineering of Drusinae larvae: head morphologies and their impact on surrounding flow fields https://contributions-to-entomology.arphahub.com/article/109206/ Contributions to Entomology 73(2): 269-278

DOI: 10.3897/contrib.entomol.73.e109206

Authors: Ariane Vieira, Hendrik C. Kuhlmann, Johann Waringer, Carina Zittra, Simon Vitecek, Stephan Handschuh

Abstract: Body morphologies are significantly different amongst the members of the Drusinae subfamily. Aligned with such differences is the selective niche location chosen by many species from the subfamily. Typically, they live on the sediments of cold, well-oxygenated mountain streams from the Eurasian Region. However, each of the three evolutionary lineages (shredders, grazers and carnivorous filter feeders) inhabit different hydraulic locations according to their foraging behaviour. To investigate the relationship between the body morphology and the flow field near the body, we use Large Eddy Simulations to compute the flow past five different species of the subfamily. We selected species representing the three evolutionary lineages of the subfamily, Drusus alpinus Meyer-Dür 1875 from the shredders clade, D. bosnicus Klapálek 1899 and D. monticola McLachlan 1876 from the grazers clade and Cryptothrix nebulicola McLachlan 1867 and D. discolor (Rambur 1842) from the filter feeders clade. For the simulations, three-dimensional body shapes were reconstructed from X-ray micro CT data and exposed to a turbulent flow corresponding to water-depth and velocity data measured in the field. The total forces acting on each morphotype were found to be comparable. The lift coefficients computed and ranging from 0.07 to 0.17 are smaller than the drag coefficients which were found to range from 0.32 to 0.55. The local distribution of the skin-friction indicates flow-separation zones near the edges of the bodies, in particular, between the head and the pronotum, which are differently located according to each species. Moreover, we observe higher streamwise normal stresses upstream of the head of the filter feeder species. It is hypothesised that the upstream horseshoe vortex can lift up drifting food particles and transport these to the larvae’s filtering legs, thereby enhancing the encounter rates of particles with the filtering devices.

Functional morphology of the genitalia of Rhyacophila lezeyi Navas, 1933 (Trichoptera, Rhyacophilidae) https://contributions-to-entomology.arphahub.com/article/109843/ Contributions to Entomology 73(2): 195-199

DOI: 10.3897/contrib.entomol.73.e109843

Authors: Ryoichi B. Kuranishi, Ryo Sato, Masashi Murakami

Abstract: We collected seven fixed pairs of Rhyacophila lezeyi during mating copulation and observed four different states of copulation. We investigated the underlying mechanism for the variations in the morphology of each copulating device, based on the copulation state. Notably, the male anal sclerites underwent considerable changes from the early stages of copulation. Initially, the female segment VIII approached the male anal sclerites, which were pushed downwards by the female VIII and IX segments, extending from IX. With the progression of mating stage, the distended end of the female’s segment VIII covered the anal sclerites, pushing them further down. The male parameres were initially folded in bellows-like shapes under the aedeagus before copulation initiation. However, as the copulation stage advanced, they extended to about 3.2 times of their original length. Distended ends of both parameres adhered to the position of the spiracles at the anterior margin of the lateral part of the female’s VII abdominal sternite. The attachment site was the external surface of the hair bulb of the male parameres. During the middle stage of copulation, movements involving the opening and closing of the male gonopods started. The gonoslylus made strong contact with the female’s abdominal segment VIII, resulting in the deformation of segment VIII due to the contact pressure.

Life cycles and larval and pupal habitats of eleven Japanese Rhyacophila (Trichoptera) species at the mountain streams in central Honshu https://contributions-to-entomology.arphahub.com/article/108102/ Contributions to Entomology 73(2): 181-194

DOI: 10.3897/contrib.entomol.73.e108102

Authors: Akikazu Taira

Abstract: The life cycles and microhabitats involved in aquatic stages of eleven Rhyacophila Stephens, 1836 species living in two neighboring Japanese mountain streams in Nara Prefecture, central Honshu, were investigated. Eight species had univoltine life cycles; seven species had spring to early summer emergence seasons. One species had an autumnal emergence. Four univoltine species had periods where no larvae or pupae were collected in aquatic stages, possibly a period of egg diapause. Three species had bivoltine life cycles, with early summer and autumn emergence seasons. Rhyacophila nipponica Iwata, 1927, R. manuleata AV Martynov, 1934, and R. shikotsuensis Iwata, 1927, in the nigrocephala species group Ross, 1956, have larvae which spend most of their larval stage in the hyporheos. The larvae of R. transquilla Tsuda, 1940, also inhabit the hyporheic zone, although the vertical microhabitat used by this species differed from the former three species. All four of these species have hyporheic larval stages, but in these species the first and final instar larvae reside on the surfaces of cobbles. The first instar larvae seem to live on stone surfaces immediately after hatching, and subsequently move to the interstices of sand. Final instar larvae live in the interstices of sandy bottom, and move to stone surfaces for pupation. Eleven species of the genus Rhyacophila had diverse life histories, microhabitat preferences, and experienced differing water temperature regimes during larval stages at the sites. Life history and habitat preference variation enhances the species richness of the genus and coexistence of species in upper stream of the Kinokawa River.

Radiation of the microcaddisfly genus Orthotrichia (Trichoptera, Hydroptilidae) in Australia https://contributions-to-entomology.arphahub.com/article/105274/ Contributions to Entomology 73(1): 113-120

DOI: 10.3897/contrib.entomol.73.e105274

Authors: Alice Wells

Abstract: Orthotrichia is the most species rich of the hydroptilid genera found in Australia, and is postulated to be a relatively recent arrival from the Oriental Region. The genus has an almost worldwide but patchy distribution, represented by close to 280 species among which the Australian fauna of 55 species represents around 20%. In an attempt to understand the radiation of the genus in Australia, this paper explores the morphology and biology of Australian species and discusses a number of contrasts with reports on the biology of congeners in the Northern Hemisphere. The possible significance of these differences in Australian representatives of the genus is suggested to have played a role in the ‘success’ of the genus in the region. The value of life history studies to our understanding of biodiversity and biogeography is emphasized.

Taxonomy, distribution and host plants of some southern European and North African Sawflies (Hymenoptera, Symphyta) https://contributions-to-entomology.arphahub.com/article/102845/ Contributions to Entomology 73(1): 9-30

DOI: 10.3897/contrib.entomol.73.e102845

Authors: Andrew Liston

Abstract: New taxonomic, biological and faunistic data are presented for some species of sawflies occurring in southern Europe and North Africa. Pamphilius mediterraneus sp. nov. is described from Italy (Sicily). It belongs to the alternans sub-group of the alternans species group. Pristiphora omalos sp. nov. is described from Greece (Crete). It belongs to the depressa species group. New junior synonyms are Calameuta tazzekae Lacourt, 1991 of Calameuta gaullei (Konow, 1896), and Emphytus leucostomus Costa, 1890 of Allantus cingulatus (Scopoli, 1763). Periclista rufiventris Zombori, 1979 is moved from the subgenus Periclista to the subgenus Neocharactus. Ametastegia (Protemphytus) persica Khayrandish, Talebi & Blank, 2015 is recorded for the first time in Europe, from Italy (Sicily), and a key to West Palaearctic Protemphytus species provided. Allantus enslini (Forsius, 1918) is more widespread in southern Europe than previously recorded. An identification key distinguishes it from its closer West Palaearctic relatives. New hostplant records are for Halidamia affinis (Fallén, 1807) (Rubia peregrina), Janus compressus (Fabricius, 1793) (Sorbus torminalis), and Macrophya albicincta (Schrank, 1776) (Centranthus ruber). New distribution records are given for a few other species.

Käfer (Coleoptera) in einem Höhengradient des Bayerischen Waldes – ein Vergleich von Naturwaldreservaten und Wirtschaftswäldern https://contributions-to-entomology.arphahub.com/article/97274/ Contributions to Entomology 72(2): 271-308

DOI: 10.3897/contrib.entomol.72.e97274

Authors: Markus Blaschke, Angela Siemonsmeier

Abstract: With ongoing climate change, alterations in forest species communities are expected. Simultaneous investigations in different temperature ranges, as they are found in mountain ranges with their different altitudinal belts, offer the possibility to take a look at this future. In 2019, the species diversity of beetles was investigated in an altitudinal gradient in the Bavarian Forest and in the neighbouring Neuburger Forest using 144 flight interception traps distributed in eight strict forest reserves and in reference areas in surrounding managed forests. In total, 16,090 individuals were identified to the species level, resulting in 716 beetle species. Rare and exceptional findings are presented and discussed. The altitudinal difference of over 1,000 m led to a distinct variation of the species composition in the different altitudinal zones. For several species of the montane region the ongoing climate change will possibly influence their survival in this region. The differences between the species communities in strict forest reserves and managed stands, with the silvicultural methods practised in this region, were quite small.

On the Geostiba fauna of Georgia. VII. Five new species from the Kakheti region and additional records (Coleoptera: Staphylinidae: Aleocharinae) https://contributions-to-entomology.arphahub.com/article/97273/ Contributions to Entomology 72(2): 259-269

DOI: 10.3897/contrib.entomol.72.e97273

Authors: Volker Assing

Abstract: Five species of Geostiba Thomson, 1858 from the Kakheti region, Northeast Georgia, are described and illustrated: Geostiba (Tropogastrosipalia) angularis spec. nov. (region to the north of Lechuri); G. (Sibiota) tbatanana spec. nov. (Tbatana Range) and G. (S.) gomborica spec. nov. (Gombori Range) of the G. bituberculata group; G. (Sibiota) bulbosa spec. nov. (Gombori Range) and G. (S.) effeminata spec. nov. (region to the south of Abano pass) of the G. carinicollis group. The distribution of Geostiba (Sipalotricha) cingulata (Eppelsheim, 1878) is revised and illustrated; a previous record from Azerbaijan is regarded as probably incorrect (result of mislabeled material). The distributions of the species of the subgenus Sibiota Casey, 1906 recorded from Georgia east of South Ossetia are mapped. Additional records of nine species are reported. The Geostiba fauna of the Caucasus region sensu lato is now represented by a total of 55 named species, 34 of which belong to the subgenus Sibiota. Twenty-six species have been recorded from Georgia.

Supplement to the Staphylinidae fauna of Crete and the Aegean Islands, Greece (Coleoptera) https://contributions-to-entomology.arphahub.com/article/97264/ Contributions to Entomology 72(2): 213-253

DOI: 10.3897/contrib.entomol.72.e97264

Authors: Volker Assing

Abstract: Recent field trips to Crete, Samos, and Rhodos, as well as a revision of other material from various collections yielded numerous additional records, species, and taxonomic changes for the Staphylinidae faunas of Crete and the Aegean Islands. Fifteen species are described and illustrated for the first time, two of the Pselaphinae, two of the Oxytelinae, two of the Aleocharinae, one of the Leptotyphlinae, and eight of the Scydmaeninae: Paramaurops creticus Brachat spec. nov. (Crete: Psiloritis range); Afropselaphus chanianus Brachat spec. nov. (Crete); Euphanias ambulans Assing spec. nov. (Samos); Bledius (Hesperophilus) bedelianus Schülke spec. nov. (Samos, Rhodos, Karpathos, South Turkey, Lebanon, Israel); Hydrosmecta cultellata Assing spec. nov. (Samos); Atheta (Philhygra) tecta Assing spec. nov. (Samothraki, Samos, Kos, Turkey); Cretotyphlus kerkisicus Assing spec. nov. (Samos); Cephennium amplexans Assing spec. nov. (Samos); C. monstrans Assing spec. nov. (Samos); C. icariae Assing spec. nov. (Ikaría); C. rhodicum Assing spec. nov. (Rhodos); Stenichnus (Stenichnus) samius Meybohm spec. nov. (Samos); S. (S.) amphimykalicus Meybohm spec. nov. (Samos, Southwest Turkey); Scydmoraphes amphimykalicus Meybohm spec. nov. (Samos, South-west Turkey); Euconnus (Tetramelus) rhodicus Meybohm spec. nov. (Rhodos). Three new synonymies are proposed: Throbalium cycladicum (Koch, 1937) = T. biblicum (Koch, 1937), syn. nov., = T. adanense Koch, 1939, syn. nov., = Throbalium kosianum Bordoni, 2020, syn. nov. Two new combinations are proposed: Tychus kerkisicus (Brachat, 2017), comb. nov. (ex Paratychus Besuchet, 1960) and Liogluta aloconotoides (Benick, 1940), comb. nov. (ex Aloconota Thomson, 1858). Several previous misidentifications are rectified. Numerous species are reported from Crete and the Aegean Islands for the first time, some even from Greece and from Europe. New checklists of the Staphylinidae of Samos and Rhodos are provided. Including the additions and changes, the faunas of Crete, Samos, and Rhodos are now represented by 403 identified named species (114 of them endemic), 199 named species (15 endemic), and 160 named species (10 endemic), respectively.
