Development, phylogeny, and taxonomy of Bostrycapulus (Caenogastropoda: Calyptraeidae), an ancient cryptic radiation

Calyptraeid gastropods are well know for the taxonomic difficulties caused by their simple, phenotypically variable shells. In this paper I demonstrate that what was previously considered to be a single species, Crepidula aculeata , is an ancient (3–15 Myr) cryptic species complex made up of at least eight species, and that this group should be placed in the genus Bostrycapulus . Despite the difficulty in finding diagnostic adult shell and anatomical features upon which species can be unambiguously identified, DNA sequences, protoconch morphology, embryonic morphology and developmental characters clearly differentiate these eight species. A single species with direct development and nurse eggs is present in the South Atlantic, and a species with planktotrophic development occurs in the equatorial Pacific. The species from Japan, Australia, Florida, the Pacific coasts of Mexico and Central America, and the Cape Verde Islands all have direct development. Most of these species are separated by > 15% divergence in COI sequence data. The fossil record of Bostrycapulus goes back to the Miocene, which agrees with genetic estimates of divergences within the genus ranging from 3 to 15 Mya. Surprisingly, these ancient species differ only slightly in morphology from each other and genetic differentiation does not correlate with geographical distance. I revise the genus Bostrycapulus on the basis of differences in adult morphology, embryonic morphology, mode of development, protoconch morphology, and DNA sequence data. I also describe four new species ( B. pritzkeri sp. nov., B. odites sp. nov., B. latebrus sp. nov. and B. urraca sp. nov. ) and remove three others ( B. gravispinosus , B. calyptraeformis , and B.  cf. tegulicius ) from synonymy with B. aculeatus .  © 2005 The Linnean Society of London, Zoological Journal of the Linnean Society , 2005, 144 , 75−101.

Revision of the Australasian genus Orussobaius Benson (Hymenoptera: Symphyta: Orussidae)

Abstract The Australasian genus Orussobaius Benson is revised. Seven species are recognised: Orussobaius paniculus sp. n. from Papua New Guinea, and six species from Australia: O. badius sp. n., O. caligneus sp. n., O. mesembrinus Benson, O. minutissimus sp. n., O. minutus Benson, and O. wilsoni Benson. Orussobaius normani Rayment (new synonymy) is removed from synonymy with O. wilsoni and treated as a junior synonym of O. minutus instead. With a body length of only 2 mm, O. minutissimus sp. n. is the smallest currently known sawfly species in the world. A key is provided and distribution maps are shown for all species. The genus Orussobaius is redefined on the basis of all species currently included.     

Revision of the Indo-Australian genus Cnematoplatys Schmidt with description of a new species from Queensland (Coleoptera: Scarabaeidae: Aphodiinae: Eupariini)

Abstract  The euparine genus Cnematoplatys Schmidt, with seven species, is reviewed, including one species, C. yorkensis described as new. The generic diagnosis is revised, a lectotype of the type species, C. benardi Schmidt, is designated, a key to the species is provided and pertinent morphological details are illustrated. All data on taxonomy and available data on distribution are given, and a cladistic analysis is included to test the monophyly of the genus.     

Key to the New Zealand species of Psyllaephagus Ashmead (Hymenoptera: Encyrtidae) with descriptions of three new species and a new record of the psyllid hyperparasitoid Coccidoctonus psyllae Riek (Hymenoptera: Encyrtidae)

Abstract  This paper records seven species of wasps in the genus Psyllaephagus (Hymenoptera: Encyrtidae) from New Zealand. All of these species are primary parasitoids of psylloids (Hemiptera: Psylloidea). Two are species previously described from New Zealand: P. acaciae Noyes and P. pilosus Noyes. Two are described Australian species which have established recently: P. bliteus Riek and P. gemitus Riek. Three new species are described here, from New Zealand: P. breviramus sp. nov., P. cornwallensis sp. nov. and P. richardhenryi sp. nov. All species are probably Australian in origin. A key to all seven Psyllaephagus species known from New Zealand is provided. An earlier first record of the Australian psyllid hyperparasitoid Coccidoctonus psyllae Riek (Hymenoptera: Encyrtidae), previously first recorded from New Zealand in 2006, is noted.     

North-east Atlantic and Mediterranean species of the genus Buffonellaria (Bryozoa, Cheilostomata): implications for biodiversity and biogeography

In this study we revise the cheilostome bryozoan genus Buffonellaria Canu & Bassler, 1927 and its Mediterranean and north-east Atlantic species, thereby addressing several existing problems. First, a lectotype for the type species, Buffonellaria divergens (Smitt, 1873) from Florida, is chosen, which proves to be distinct from the European species. Second, the two hitherto established north-east Atlantic species [ Buffonellaria nebulosa ( Jullien & Calvet, 1903 ) and Buffonellaria porcellanum Arístegui Ruiz, 1987], are redescribed, which were poorly documented until now. Third, close inspection of material, collected from Spitsbergen to tropical West Africa, using scanning electron microscopy reveals that the actual number of species, all previously referred to either B. divergens or Stephanosella biaperta (Michelin, 1848), is distinctly greater in the north-east Atlantic than has been previously acknowledged. As a result, seven new species are introduced ( Buffonellaria acorensis sp. nov. , Buffonellaria antoniettae sp. nov. , Buffonellaria arctica sp. nov. , Buffonellaria harmelini sp. nov. , Buffonellaria jensi sp. nov. , Buffonellaria muriella sp. nov. , and Buffonellaria ritae sp. nov. ), whereas two are left in open nomenclature. With the increase in number of species, the extremely broad geographical range of distribution assumed for B. divergens breaks down to numerous restricted areas. However, although most species have only been reported from a single location, B. arctica sp. nov. seems to have a fairly wide distribution in the Arctic region.  © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society , 2008, 152 , 537–566.     

Molecular diversification of salamanders of the tropical American genus Bolitoglossa (Caudata: Plethodontidae) and its evolutionary and biogeographical implications

The largest genus of salamanders, Bolitoglossa (Plethodontidae), is widespread in tropical America, where it occurs in diverse habitats and elevations, from high elevation grasslands to lowland rain forest . It has the most extensive geographical range of any salamander genus. While most species occur in Middle America, it ranges throughout most of tropical South America as well. Phylogenetic analysis of 1196 bp of two mitochondrial genes (cytochrome b , 16S RNA) from 55 species offers strong support for the monophyly of the genus and sorts the species into a number of clades. Taking into account morphology, distribution, general ecology, and prior systematic and taxonomic studies, we recognize seven subgenera, four of them new: Bolitoglossa Duméril, Bibron et Duméril, 1854, Eladinea Miranda Ribeiro, 1937, Magnadigita Taylor, 1944, Mayamandra , Nanotriton , Oaxakia and Pachymandra . All South American and some lower Middle American species are included in a single well -supported clade, Eladinea . At the species level our analyses uncover the existence of large genetic diversity within morphologically homogeneous taxa. We propose the new combination: B. (Eladinea) paraensis (Unterstein, 1930) stat. nov. , for Brazilian salamanders previously included under B. altamazonica . We evaluate evidence for the multiple colonization of the tropical lowlands by morphologically derived species groups. South America was invaded by members of one clade, Eladinea , which we infer to have dispersed to South America prior to closure of the Panamanian Portal. Despite the relatively long history of salamanders in South America, that continent now accounts for a relatively small proportion of the lineages and species of neotropical salamanders.  © 2004 The Linnean Society of London, Biological Journal of the Linnean Society, 2004, 81 , 325–346.     

Comparative biology of pollination systems in the African-Malagasy genus Brownleea (Brownleeinae: Orchidaceae)

The role of pollinators in the evolution of the African-Malagasy orchid genus Brownleea (Brownleeinae) was investigated. Taxa show specialization for pollination by bees ( B. parviflora , B. recurvata ), short-proboscid flies ( B. galpinii ), and long-proboscid flies ( B. macroceras , B. coerulea ). All species in the genus produce nectar, but some ( B. coerulea , B. galpinii ) appear to mimic flowers of abundant sympatric species as an additional strategy to attract pollinators. Species investigated in terms of their breeding systems ( B. coerulea , B. parviflora , B. macroceras , B. galpinii ) are reliant on pollinator visits for seed production. Self-pollination results in strong inbreeding depression during embryo formation. A phylogeny of the genus, constructed using data from the ITS1-5.8S-ITS2 region and morphology, indicates that fly pollination is likely to be basal in the genus, and that there has been a single shift to bee pollination.  © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society , 2008, 156 , 65–78.     

Systematics and biogeography of the New World species of Trichadenotecnum Enderlein (Insecta: Psocodea: 'Psocoptera': Psocidae)

The taxonomy of the New World species of the genus Trichadenotecnum is revised. A total of 44 species, including 29 new species, were treated. These species are classified into 12 monophyletic species groups, eight of them newly proposed here. Two species previously assigned to Trichadenotecnum , T. pichincha New & Thornton and T. sylvaticum Turner, are recognized as not belonging to this genus. Phylogenetic relationships among 16 previously and presently proposed species groups are estimated based on a data matrix of 58 morphological characters. Trees from these analyses support monophyly of Trichadenotecnum and the proposed species groups. The New World species were divided into three major clades. Based on the phylogenetic hypothesis and distributional pattern of the species groups, the biogeographical history of the New World Trichadenotecnum is discussed.  © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society , 2008, 153 , 651–723.     

Survey of the native insect natural enemies of Hyphantria cunea (Drury) (Lepidoptera: Arctiidae) in China

The fall webworm, Hyphantria cunea (Drury) (Lepidoptera: Arctiidae), is an invasive and important pest in China. Investigations on insect natural enemies have been conducted from 1996 to 1999 in five provinces and one municipality of China in order to select effective species for biological control. Two carabid predators (Coleoptera) and 25 parasitoid species were found, among which 23 were parasitic wasps (Hymenoptera), including five hyperparasitic species and two tachinid flies (Diptera). The two carabids preyed on young larvae inside webs, two braconid wasps parasitized larvae, and 18 parasitoid species attacked the fall webworm during the pupal and/or 'larval-pupal' stages. Among these parasitoids, there were one genus and nine species that are new to science and four species new to China, which were described and published by the senior author Yang. The average parasitism rates of fall webworm pupae were 25.8% and 16.1% in the overwintering generation and the first generation (summer generation), respectively. These findings reveal that these natural enemies play an important role in the natural control of the pest. Chouioia cunea Yang (Hymenoptera: Eulophidae), a gregarious pupal endo-parasitoid, was recommended as a promising biological control agent against the fall webworm in China.     

New peculiar entedonine genus (Hymenoptera: Chalcidoidea: Eulophidae) from Western Australia

Abstract Clypecharis gen. n. is described for a new species C. rostrifera sp. n. from Western Australia. The new genus is characterised by the unique shape of the lower face, which is produced into a peculiar forked rostrum, and by the elongate mandibles situated in a 'crossbill"s beak' position. The flagellum of the new species is shortened and clavate. Its segments are very closely approximated, with the two-segmented funicle hardly distinguishable from the three-segmented clava. The morphological peculiarities of Clypecharis and its possible relationships with other entedonine genera are discussed.     

Systematics, phylogeny and biogeography of Anterastes (Orthoptera, Tettigoniidae, Tettigoniinae): evolution within a refugium

Çıplak, B. (2004). Systematics, phylogeny and biogeography of Anterastes (Orthoptera, Tettigoniidae, Tettigoniinae): evolution within a refugium. — Zoologica Scripta , 33 , 19–44.
The genus Anterastes , distributed in southeastern Europe and the western part of Anatolia, is revised based on previous materials and numerous specimens collected from new localities. A key to all species is presented. Two new species, A. antitauricus sp. n. and A. ucari sp. n. are described. Anterastes akdaghensis Ramme is placed in synonymy with A. babadaghi Uvarov. Cladistic analysis confirmed the monophyly of Anterastes . The relationships among the species of Anterastes are: A. uludaghensis  + (( A. serbicus  +  A. burri  +  A. antitauricus sp. n.) + ( A. anatolicus  +  A. tolunayi  + ( A. niger  + ( A. babadaghi  +  A. turcicus  +  A. ucari sp. n.)))). The biogeography of the genus shows a correlation with its phylogeny. It is assumed that the genus arose from an ancestral stock in northwestern Anatolia in the Pliocene and the later range of this ancestral population expanded and contracted under the effects of the ice ages (glacial and interglacial periods, respectively). It is postulated that speciation within the genus, suggested by phylogenetic analysis, might have occurred when the range of ancestral populations expanded during glacial periods and contracted in subsequent warm periods. The present species may be the product of relict populations remaining in refugia at higher altitudes with alpine or subalpine vegetation in southern Anatolia.     

A new genus and species of Cyphophthalmi (Arachnida: Opiliones) from the north-eastern states of India

We describe a new genus and new species of Cyphophthalmi from north-eastern India, from the unexplored and extremely wet region lying between China, Bangladesh, Myanmar, and Bhutan. Meghalaya annandalei   sp. nov. , from the Mehao Wildlife Sanctuary, Arunāchal Pradesh, is an interesting Cyphophthalmi, with eyes located anterior to the ozophore, a modified tibia of leg III of males, and a robust subtriangular adenostyle. The new genus has overall resemblance to the members of the family Stylocellidae, but also has important differences for other characters, which resemble those of the members of the other tropical families Ogoveidae and Troglosironidae. The discovery of additional specimens belonging to other undescribed species indicates the need for arachnological research in that part of south-eastern Asia.  © 2007 The Linnean Society of London, Zoological Journal of the Linnean Society , 2007, 151 , 663–670.
