A new subterranean species of Entomoculia Croissandeau, 1891 from the Canary Islands, Spain (Coleoptera, Staphylinidae, Leptotyphlinae) https://contributions-to-entomology.arphahub.com/article/112399/ Contributions to Entomology 74(1): 1-6

DOI: 10.3897/contrib.entomol.74.e112399

Authors: Carles Hernando, Heriberto López

Abstract: The genus Entomoculia Croissandeau, 1891, is the only representative of the subfamily Leptotyphlinae present in the Canary Islands and is composed by only two species: E. (Stenotyphlus) canariensis Outerelo, 1982, from La Gomera and E. (Stenotyphlus) lauricola Outerelo & Hernández, 1989, from Tenerife, both found in deep soil (= endogean) habitats. In this paper, we describe Entomoculia (Stenotyphlus) vulcanica sp. nov., the third Canarian species of the genus, which is reported for the first time from Gran Canaria and has been found in the mesovoid shallow substratum “MSS”. This new species has some of the characteristics that are specific to Canarian species of the genus Entomoculia, such as the lack of a denticle or spiniform process on the male metatrochanters. However, it is a remarkable species as it is the only known species of the genus with a tridentate labrum, as the labrum is monodentate in the species so far known from Canary Islands and bidentate in non-Canary species. We provide a key to Canarian species and illustrations of the habitus and the primary and secondary sexual characters of the male. We also describe the sampling techniques used and provide detailed information on habitat characteristics and associated arthropod fauna.

High altitude morphotype of the widespread Lobrathium multipunctum (Gravenhorst, 1802) (Coleoptera, Staphylinidae, Paederinae) revealed by DNA-barcoding https://contributions-to-entomology.arphahub.com/article/102511/ Contributions to Entomology 73(1): 1-8

DOI: 10.3897/contrib.entomol.73.e102511

Authors: Aslak Kappel Hansen, Josh Jenkins Shaw

Abstract: High altitude ecosystems are often home to endemic species that have evolved in isolation from their low elevation counterparts. In many cases, especially in insects, such mountain endemics are often apterous (due to their reduced ability to fly and disperse). In most cases, so far, these mountain endemics are genetically differentiated from lowland sister species or populations. During an excursion in Central Spain, we encountered two such strikingly different morphotypes of the rove beetle Lobrathium multipunctum (Gravenhorst, 1802) (Coleoptera, Staphylinidae, Paederinae). The morphotype from high elevation was smaller and paler than those at low elevation, which were slightly larger, darker and regularly coloured. The high altitude morphotype was earlier considered a separate species (Lobrathium hispanicum Dodero, 1916) from its widespread lower-land counterpart (Lobrathium multipunctum (Gravenhorst, 1802)) before their relatively recent synonymy. Using the cytochrome c oxidase subunit I (COI) barcode region, we tested whether these distinct morphotypes are distinct species. We found that their synonymy is supported, based on multiple species delimitation methods. We suggest that this phenomenon may be more widespread amongst insects and other organismal groups. We note that the presence of high altitude morphotypes which are phylogenetically nested within, or genetically identical to, widespread lowland species (regular morphotype) is rarely reported in the literature on beetles (and other insects). These findings thus highlight the need for caution when describing mountain endemics and further highlight DNA barcoding as a helpful tool for their study.

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.

Daniel, 1904 (Coleoptera, Curculionoidea) https://contributions-to-entomology.arphahub.com/article/97253/ Contributions to Entomology 72(2): 179-211

DOI: 10.3897/contrib.entomol.72.e97253

Authors: Christoph Germann, Carlo Braunert, André Schütte

Abstract: We provide first records for 108 weevils species sensu lato (Curculionoidea) to the fauna of Montenegro. During a field trip 203 weevil species were recorded and are listed here. The records of Archarius anatoliensis Voss, 1962 are the first ones from the Balkans and document a further spreading of this species towards Northwest. Echinodera bryneri spec. nov. is described and compared with the sympatrically occurring, morphologically similar species E. romanboroveci Stüben, 1998. The lectotypes of Sciaphobus paliuri Apfelbeck, 1908, and S. polydrosinus Apfelbeck, 1922 conserved in the Georg Frey collection are designated, and illustrated comments on their differentiation are provided. For Leiosoma komovicum Pedroni, 2018 habitat, images of both sexes, a description of the female genitalia, and the presumable host plants are presented.

The Neotropical species of the genus Somoleptus Sharp, 1885 (Coleoptera: Staphylinidae: Staphylininae: Xantholinini) https://contributions-to-entomology.arphahub.com/article/87211/ Contributions to Entomology 72(1): 123-178

DOI: 10.3897/contrib.entomol.72.e87211

Authors: Ulrich Irmler

Abstract: At present, 45 Somoleptus species are known from the Neotropical region. Among these, 28 species are newly described here, whereas 18 were described in the past. The new species are: S. admirabilis spec. nov., S. andersoni spec. nov., S. ashei spec. nov., S. beniensis spec. nov., S. brevipennis spec. nov., S. breviusculus spec. nov., S. brooksi spec. nov., S. brunneus spec. nov., S. curtipennis spec. nov., S. curtulus spec. nov., S. elongatulus spec. nov., S. gigas spec. nov., S. grandiconus spec. nov., S. humicola spec. nov., S. longiceps spec. nov., S. loretensis spec. nov., S. maximus spec. nov., S. melanarius spec. nov., S. mexicanus spec. nov., S. montanus spec. nov., S. oculatus spec. nov., S. ovatus spec. nov., S. pecki spec. nov., S. peruanus spec. nov., S. recurvatus spec. nov., S. struyvei spec. nov., S. triangulus spec. nov., S. tschirnhausi spec. nov. Four species are transferred from the genus Lithocharodes. These are S. cavicola (Blackwelder, 1943) comb. nov., S. strigulata (Blackwelder 1943) comb. nov., S. longicollis (LeConte, 1863) comb. nov., and S. subtilis (Erichson, 1839) comb. nov. Somoleptus dichiformis Bernhauer, 1910 could not be assigned to either Lithocharodes or Somoleptus. Thus, this species must be treated as species incertae sedis. Two species groups could be differentiated due to the structure of the parameres and the aedeagal cones; one mainly occurs in South America, the second in Central America.

DOI: 10.3897/contrib.entomol.72.e87233

Authors: Volker Brachat, Volker Assing

Abstract: Three microphthalmous and presumably locally endemic species of Tychobythinus Ganglbauer, 1896, a pselaphine genus previously unknown from Georgia, are described and illustrated: T. meskheticus spec. nov. (Southwest Georgia: Meskheti Range), T. eximius spec. nov. (Northwest Georgia: Egrisi Range), and T. egrisicus spec. nov. (Northwest Georgia: Egrisi Range). Tychobythinus eximius is particularly remarkable in that it is subject to a unique sexual dimorphism of the antennae and the pronotum. Including the new species, Tychobythinus is now represented in the Palaearctic region by 95 named species and two subspecies.

On the taxonomy and zoogeography of the Caucasian genus Pseudotyphlopasilia (Coleoptera: Staphylinidae: Aleocharinae). IV. Two new species and additional records from Northwest Georgia https://contributions-to-entomology.arphahub.com/article/87240/ Contributions to Entomology 72(1): 81-87

DOI: 10.3897/contrib.entomol.72.e87240

Authors: Volker Assing

Abstract: Two field trips to Northwest Georgia conducted in 2021 yielded 29 specimens of the Caucasian genus Pseudotyphlopasilia Pace, 1983, most of them collected by soil-washing. The material belongs to five species, two of them described and three of them unnamed. Two of the unnamed species are described and illustrated: P. confusa spec. nov. (Racha: environs of Lailashi) and P. egrisica spec. nov. (Zemo Svaneti: Egrisi Range). One species remains unnamed for want of males. Additional records are provided for two previously described species, including Pseudotyphlopasilia coeca (Eppelsheim, 1878) (type species of the genus) of which only few and mostly old specimens were previously available. New illustrations are provided for P. coeca and P. acris Assing, 2021. The genus currently contains a total of twelve named species, all of them anophthalmous and micropterous, with eleven of them distributed in Georgia and one in the Russian West Caucasus. The distributions of five species are mapped.
