The singing cicada Cicadetta cantilatrix Sueur et Puissant, 2007, only recently described from Western Europe, was found in Russia. The acoustic repertoire of this species is studied, oscillograms and sonograms of the signals emitted by individuals from the south of Moscow Province are provided for the first time.     

The genus Cyprideis Jones, 1857 (Crustacea,Ostracoda) in the Neogene of Italy: A geometric morphometric approach

As a result of the use of geometric morphometrics, multivariate statistics and classical morphological observations the authors propose a taxonomic revision of the Neogene Italian Cyprideis species. On this basis, the Cyprideis valves collected in Tortonian, Messinian and Pliocene brackish deposits of Italy are referred to 12 species, six of which are new: Cyprideis alexandri nov. sp., Cyprideis arvedoi nov. sp., Cyprideis lepianensis nov. sp., Cyprideis rooki nov. sp., Cyprideis strollae nov. sp., and Cyprideis toscana nov. sp. Some species are rather widespread in the Italian Peninsula (Cyprideis ruggierii Decima and Cyprideis crotonensis Decima) or even in the whole Palaeomediterranean (Cyprideis agrigentina Decima and Cyprideis anlavauxensis Carbonnel). For C. ruggierii, C. agrigentina and C. crotonensis, a phyletic relation is suggested. The new species are confined both geographically and stratigraphically in several Tuscan athalassic brackish basins, suggesting endemic speciation similar to those occurring in ancient lakes.     

Acoustic adaptations to anthropogenic noise in the cicada Cryptotympana takasagona Kato (Hemiptera: Cicadidae)

Anthropogenic noise produced by human activities affects acoustic communication in animals living in urban habitats. We recorded the calling songs of the cicada Cryptotympana takasagona in the Kaohsiung metropolitan areas of southern Taiwan to investigate possible acoustic adaptations to anthropogenic noise. C. takasagona did not call more in noise gaps. Acoustic features (peak frequency, quartile 25%, quartile 50%, and quartile 75%) of calling songs significantly increased with ambient noise levels. C. takasagona shifted the energy distribution of calling songs to higher frequencies in the presence of higher noise levels. We suggest that the acoustic adaptation by which song frequencies increase with levels of anthropogenic noise in C. takasagona may result from a size-dependent calling strategy in which small-sized males call more in noise conditions or large-sized males adjust their song frequency by changing their abdominal cavities.     

Asymmetric song responses in coexisting Japanese cicadas

Diel partitioning of singing, which has been observed from the tropics to the temperate regions, is among the various mechanisms of sound partitioning found in multispecies cicada assemblages and is regarded as an important mechanism of coexistence. Using playback experiments, we studied interspecific interference between two Japanese cicadas, Cryptotympana facialis and Graptopsaltria nigrofuscata, which exhibit similar peak frequencies in their calling songs and different diel patterns of song activity. We found that the males of the two species had different song response patterns: C. facialis responded significantly more to conspecific calling songs than G. nigrofuscata. These results suggest that male C. facialis have evolved more intense conspecific song recognition than G. nigrofuscata. This may cause male G. nigrofuscata to avoid destructive acoustic interference during their active singing time.     

Systematic revision of the genus Everettia Godwin‐Austen, 1891 (Mollusca: Gastropoda: Dyakiidae) in Sabah,northern Borneo

The species of the snail genus Everettia in the Malaysian state of Sabah are superficially similar and difficult to distinguish by their shells. This paper presents new data on the taxonomy and distribution of Everettia in Sabah that have accumulated since the revision by Godwin‐Austen in 1891. By using morphological and molecular phylogenetic approaches, we reveal at least seventeen species of Everettia in Sabah, of which eleven are new to science, namely: Everettia layanglayang sp. nov. , Everettia lapidini sp. nov. , Everettia paulbasintali sp. nov. , Everettia occidentalis sp. nov. , Everettia jasilini sp. nov. , Everettia safriei sp. nov. , Everettia interior sp. nov. , Everettia jucundior sp. nov. , Everettia planispira sp. nov. , Everettia monticola sp. nov. , and Everettia dominiki sp. nov. , and one new subspecies, namely, Everettia corrugata williamsi ssp. nov. Phylogenetic analysis of mitochondrial COI and 16S, and nuclear ITS‐1 sequences demonstrates the monophyly of most of the morphologically well‐defined species. Our results show that certain aspects of classical morphology‐based taxonomy for Everettia species, especially with regard to the unique combination of shell surface sculptures, animal head colour, and mantle pigmentation, are solid. A dichotomous key to the Sabah species and subspecies of Everettia is provided. © 2009 The Linnean Society of London, Zoological Journal of the Linnean Society, 2009, 157 , 515–550.     

The Hawaiian amphibious caterpillar guild: new species of Hyposmocoma (Lepidoptera: Cosmopterigidae) confirm distinct aquatic invasions and complex speciation patterns

Although aquatic caterpillars are a globally rare lifestyle, we have found them in multiple, independent lineages of the endemic moth genus Hyposmocoma across all of the Hawaiian Islands with flowing water. We formally describe 11 new species of Hyposmocoma that belong to four different larval case types: cone, bugle, medium burrito, and large burrito: Hyposmocoma kahamanoa sp. nov. from Oahu Island, Hyposmocoma kamakou sp. nov. from Molokai Island, Hyposmocoma kahaiao sp. nov. , Hyposmocoma waihohonu sp. nov. , and Hyposmocoma moopalikea sp. nov. from Maui Island, and Hyposmocoma aumakuawai sp. nov. , Hyposmocoma eepawai sp. nov. , Hyposmocoma ipowainui sp. nov. , Hyposmocoma kawaikoi sp. nov. , Hyposmocoma uhauiole sp. nov. , and Hyposmocoma wailua sp. nov. from Kauai Island. We also illustrate and describe in detail the aquatic case‐bearing larva of Hyposmocoma kahamanoa. Despite having similar ecologies as algae and lichen grazers at and below the water line of streams, prior research indicates that species with each case type constitute an independent lineage, with terrestrial sister taxa, and therefore the different groups of species bearing unique case types each represent an independent aquatic invasion. The case‐bearing larvae often occur sympatrically, and on Kauai even species with similar case‐types occur together, suggesting complex patterns of speciation and either past periods of isolation or sympatric speciation. Phylogenetic analysis of 2243 base pairs from two nuclear and one mitochondrial gene for 18 species confirm that each species is endemic to a single volcano, and that morphological divergence within case‐types has not been dramatic. Diversification has been complex, and superficially similar case type lineages are not all monophyletic. Kauai, the oldest but smallest of the major high islands, supports more species in the aquatic guild than any other island, thus island age, rather than size, may be important in generating diversity in this group. © 2011 The Linnean Society of London, Zoological Journal of the Linnean Society, 2011, 162 , 15–42.     

Taxonomic review of Hemistola Warren, 1893 from China,with descriptions of seven new species (Lepidoptera: Geometridae,Geometrinae)

The genus Hemistola Warren from China is reviewed, and seven new species are described: H. viridimargo, sp. nov., H. glauca sp. nov., H. asymmetra sp. nov., H. arcilinea sp. nov., H. flavifimbria sp. nov., H. orbiculosoides sp. nov. and H. stueningi sp. nov. Two species, acyra and christinaria, are transferred from Hemistola to Maxates and Comostola, respectively: Maxates acyra comb. nov. and Comostola christinaria comb. nov. Including the 25 species previously known from China, a total of 32 species is now recorded. All Chinese species are redescribed. Generic characters based on all species are summarized. Illustrations of adults and genitalia are presented.     

Biodiversity eavesdropping: bioacoustics confirms the presence of Cicadetta montana (Insecta: Hemiptera: Cicadidae) in France

Using bioacoustic methods only, we confirm the presence of Cicadetta montana s. str. in France, a cicada belonging to a complex of closely related species. Specimens of C. montana from France have probably been kept in collections for a long time but could not be identified with certainty by morphological characters alone. The species was discovered in a single locality but it is highly probable that it will be found in many other parts of the country in particular in the north and east of France. This simple study illustrates how much bioacoustic studies can help in monotoring biodiversity, in particular biodiversity of closely related species and/or of species living in habitats difficult to reach or where visual contact is highly limited.     

An integrative approach to characterize cryptic species in the Thoracostoma trachygaster Hope, 1967 complex (Nematoda: Leptosomatidae)

Nematode diversity may seriously be underestimated when taking into account cryptic speciation. Thoracostoma trachygaster is commonly found in kelp holdfasts along the California coastline and was recently shown to consist of at least two distinct molecular clades (I and II). Here, we provide detailed morphological analysis of both clades, based on measurements taken from video vouchers of respectively eight and 16 individuals from the previous study, as well as 80 newly collected specimens from four Californian beaches. The latter were vouchered, measured, and then subjected to molecular analyses of the mitochondrial cytochrome oxidase c subunit I (COI) gene, and the ribosomal D2D3 and internal transcribed spacer (ITS) regions. This integrative approach shows that the three molecular clades are phylogenetically and morphologically distinct species, but a combination of morphological characters is needed to distinguish them. Two new species, Thoracostoma fatimae sp. nov. and Thoracostoma igniferum sp. nov. , are identified and described. The spicule length of T. fatimae sp. nov. is significantly shorter than that of T. trachygaster. Thoracostoma igniferum sp. nov. can be distinguished by the irregular posterior edge of the cephalic capsule and the two internal subdorsal tropis‐like projections in the wall of the cephalic capsule, which are lacking in T. fatimae sp. nov. and T. trachygaster. © 2012 The Linnean Society of London, Zoological Journal of the Linnean Society, 2012, 164 , 18–35.     

The Psyllids (Homoptera: Psylloida) of Alaska

A key is provided for the identification of the thirty-eight psyllid species recorded from Alaska. Additional notes on host plant and distribution are given for each species. The species are: Aphalara manitobaensis Cald.,A.nigra Cald., Craspedolepta alaskensis (Ash.), C.nebulosa (Zett.) ssp. kincaidi (Ash.), C. schwarzi (Ash.), C.subpunctata (Förster), Psylla alaskensis Ash., P.betulaenanae Oss., P.breviata Patch, P.fibulata Crawf., P.floccosa Patch, P.galeaformis Patch, P.haliaeeti sp.nov., P.hamata Tuthill, P.highwoodensis sp.nov., P.jenseni sp.nov., P.kananaskensis Hod., P.ledi Flor., P.longiforceps sp.nov., P.minor Crawf., P.macleani sp.nov., P.myrtilli Wag. ssp. canadensis Hod., P.palmeni Löw, P.phlebophyllae sp.nov., P.rara Tuthill, P.rufipennis sp.nov., P.sinuata Crawf., P.striata Patch, P.stricklandi Crawf., P.toolikensis sp.nov., P.zaecevi Sulc, Trioza albifrons Crawf., Trioza artica sp.nov., T.atkasookensis sp.nov., T.incerta Tuthill, T.salicivora Reut. (=T.maura auctt. N.Amer.), T.stylifera Patch, Trioza sp.nov. (undescribed). All the newly described species were collected on Salix. The Alaskan fauna is made up of four major components: 1, true Arctic species; 2, Arctic/subarctic species; 3, subarctic/alpine species; 4, northern forest zone species. Eight of the Alaskan psyllids exhibit an holarctic distribution and there is a strong faunal affinity with similar areas in northern Scandinavia: the same four genera recur throughout the northern holarctic. There is strong circumstantial evidence that certain psyllid species are parthogenetic over part of their range, particularly in arctic/alpine situations.     

Revision of the Indo‐African Pachycerus Schoenherr, 1823, with a description of four new species (Coleoptera: Curculionidae: Lixinae)

The Indo‐African species of the genus Pachycerus (Curculionidae: Lixinae: Cleonini) are revised. The identification of Cleonus senegalensis Gyllenhal, 1834 is discussed, its holotype rediscovered and the synonymy between C. senegalensis and Ammocleonus hieroglyphicus (Olivier, 1807) is confirmed. A neotype is established for Pachycerus opimus (Gyllenhal, 1834). Lectotypes for Pachycerus vestitus (Fåhraeus, 1834), Pachycerus badeni (Faust, 1888), and Pachycerus sellatus Faust, 1904 are designated. Pachycerus sahelicus sp. nov. (type locality: Senegal, Bambey), Pachycerus hippali sp. nov. (type locality: Saudi Arabia: Jeddah, Taif), Pachycerus barclayi sp. nov. (type locality: southern India: Manapparai), and Pachycerus simonae sp. nov. (type locality: Morocco, Western Sahara, Cap Boujdour) are described. Some remarks on taxonomy and biogeography of the species are added.     

A new genus and species from Borneo and a new species from Java and Sumatra of Cicadini (Hemiptera: Cicadidae)

A new cicada genus and species, Minilomia triquetra, gen. and sp. nov., is described from Borneo. The new genus Minilomia is closely allied to Platylomia Stål and is placed in the subtribe Dundubiina of the tribe Cicadini. Another new cicada species, Pomponia brevicaudata, sp. nov. (subtribe Psithyristriina), is described from Java and Sumatra. The new species belongs to the Pomponia linearis species group and the P. linearis species complex but is distinguished from its congeners by the unusually short male abdomen.     

Renewed sampling of inland aquatic habitats in southern Africa yields two novel freshwater crab species (Decapoda: Potamonautidae: Potamonautes)

A recent survey of the freshwater streams of the Mecula and Yao mountains in the Niassa province of Mozambique resulted in the discovery of a new freshwater crab species. This species is genetically and morphologically distinct from described species from Mozambique or its neighbouring countries, and is described as P otamonautes bellarussus sp. nov. In addition, a new semi‐terrestrial burrowing freshwater crab P otamonautes flavusjo sp. nov. from the Highveld of the Mpumalanga province in South Africa is described based on unique genetic and morphological characters. The phylogenetic affinities of the two new species in relation to the described eastern and southern African Potamonautes species is determined and the biogeographic implications are discussed. © 2014 The Linnean Society of London

Study of the Rotatoria‐Fauna of the Littoral of the Rio Branco,South of Boa Vista,Northern Brazil

From a study of the permanent shallow water in the savanna near Boa Vista, Brazil, a littoral sample was brought back by Dr. G.‐O. Brandorff ; Ahrensburg, which he gave me to examine. The analysis of the material, about 50 ml, showed 149 identifiable species as well as some preservative artifacts. Six species were hitherto unknown to that area. They were identified as the following: Cephalodella brandorffi nov. sp., Dicranophorus difflugarium (Penard , 1924), Eothinia triphea (Harring and Myers , 1924), Lecane bulla papillosa nov. ssp., Macrochaetus paggiensae nov. sp., Notommata falcinella (Harring and Myers , 1922), and Habrotrocha pusilla pusilla (Bryce , 1893).
