Three new species of Orphninotrichia Mosely (Trichoptera: Hydroptilidae) from Barrington Tops, New South Wales, a distribution extended, and remarks on generic placement

Abstract Three new species are described in the endemic Australian microcaddisfly genus Orphninotrichia Mosely (Trichoptera: Hydroptilidae: Hydroptilinae), all collected in the Barrington Tops area of north-eastern New South Wales: Orphninotrichia bilobata sp. n., O. claviculata sp. n. and O. dundungra sp. n. From the same area, Orphninotrichia papillata Wells, described from central Victoria, is newly recorded and noted for the atypical presence of a large gland on the dorsum of the male head. Comments are made on the still unresolved affinities of the genus Orphninotrichia , and a key to males of all species is provided.     

Revision of the New Caledonian endemic genus Gracilipsodes (Trichoptera: Leptoceridae: Grumichellini)

The taxonomy and systematics of the New Caledonian endemic caddisfly genus Gracilipsodes Sykora, 1967 (Trichoptera: Leptoceridae: Grumichellini) are reviewed. Seven new species represented by males are described and illustrated: Gracilipsodes aoupiniensis sp. nov. , Gracilipsodes aureus sp. nov. , Gracilipsodes aurorus sp. nov. , Gracilipsodes grandis sp. nov. , Gracilipsodes koghiensis sp. nov. , Gracilipsodes lanceolatus sp. nov. , and Gracilipsodes robustus sp. nov. Molecular phylogenetic analyses are applied to discern the relationships among the species of the genus and their closest relatives, based on sequence characters from the nuclear gene translation elongation factor-1α (EF-1α) and the three mitochondrial genes cytochrome oxidase I (COI), COII, and ribosomal large subunit (16S). The data are analyzed using parsimony and Bayesian inference, revealing a monophyletic Gracilipsodes with the eastern Australian monotypic genus Triplexa as its closest relative. Gracilipsodes is in turn divided into two major lineages.  © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society, 2008, 153 , 425–452.     

The first parasitic Trichoptera

Abstract.

• 1 A parasitoid habit is confirmed in larvae of an Australian micro-caddisfly, Orthotrichia muscari Wells, being the first known incidence of this habit in the order Trichoptera.
• 2 Larvae of O.muscari are non-specific parasites of pupae of other caddisfly species.
• 3 O.muscari is in an Australian/New Guinean/SE Asian species group in Orthotrichia, all members of which probably share the habit. Their larvae and pupae have atypical features that are interpreted as adaptations to their uncharacteristic niche.

     

Systematics of the spider genus Metabus O. P.-Cambridge, 1899 (Araneoidea: Tetragnathidae) with additions to the tetragnathid fauna of Chile and comments on the phylogeny of Tetragnathidae

The spider genus Metabus (Tetragnathidae) previously included nine species: the type M. gravidus O. P.-Cambridge, 1899 – junior synonym of Leucauge ocellata (Keyserling) – from Central America and eight species from Chile. In this paper, the classification of the Metabus species-complex is revised, and two new genera, with three new species and five new combinations, are described. Allende gen. nov. is created for four Chilean species not congeneric with the type of Metabus : the type A. puyehuensis sp. nov. , A. patagiatus (Simon) comb. nov. , A. nigrohumeralis (F. O. P.-Cambridge) comb. nov. and A. longipes (Nicolet) comb. nov. Further additions to the Chilean fauna are under the new genus Mollemeta gen. nov. – created for M. edwardsi (Simon) comb. nov. – and three new species of Chrysometa : C. acinosa sp. nov. , C. levii sp. nov. and C. maitae sp. nov. Metabus now includes four species: M. ocellatus (Keyserling) comb. nov. , M. debilis (O. P.-Cambridge) comb. nov. , M. ebanoverde sp. nov. and M. conacyt sp. nov. All of these species were included in a phylogenetic analysis of 38 tetragnathid and 12 orbicularian outgroup terminals scored for 105 morphological and behavioural characters. The results suggest that Metabus as previously circumscribed is polyphyletic. The phylogenetic relationships within tetragnathids are briefly discussed. © 2007 The Linnean Society of London, Zoological Journal of the Linnean Society , 2007, 151 , 285–335.     

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.     

Systematics of the bryozoan genus Macropora (Cheilostomata)

Macropora is a distinctive genus of anascan cheilostomes. All species have large zooids with an extensive cryptocystal frontal shield perforated by numerous pores through which parietal muscle strands pass. Also characteristic of Macropora are the calcified opercula closing the d -shaped orifice, avicularia resembling autozooids but having slightly enlarged, typically crenulated opercula/mandibles, and large ovicells that are often costate. This mostly Australasian genus has a documented fossil record stretching back to the Eocene. Here we revise the generic diagnosis of Macropora and describe eight new species from New Zealand (three Recent: M. nodulosa sp. nov. , M. filifera sp. nov. and M. carlosi sp. nov. ; five fossil: M. septispinosa sp. nov. , M. similis sp. nov. , M. pittensis sp. nov. , M. leeae sp. nov. and M. bullata sp. nov. ) and one new species from Japan ( M. mawatariorum sp. nov. ), the only species known with certainty to occur in the northern hemisphere. New observations are given for some previously described species, several of which are illustrated using SEM for the first time. The northern hemisphere Upper Cretaceous species Monoporella exsculpta (Marsson), showing features allowing it to be placed tentatively in the stem-group of Macropora , is redescribed. Attempts to resolve the phylogenetic relationships of species within Macropora were hampered by the relatively few morphological characters compared with the number of species, and it proved impossible to obtain a phylogeny robust to slight changes in taxon and/or character inclusion. The favoured cladogram has poor bootstrap and Bremer support, and its stratigraphical and biogeographical congruences are low.  © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society , 2008, 153 , 115–146.     

New species of caddisflies (Insecta: Trichoptera) from the Rovno amber,Eocene of Ukraine

A new genus and seven new species of the caddisfly families Philopotamidae, Polycentropodidae, Ecnomidae, Hydroptilidae, and Leptoceridae (Wormaldia nasticentia sp. nov., Holocentropus flexiflagrum sp. nov., Electrocyrnus perpusillus gen. et sp. nov., Archaeotinodes reveraverus sp. nov., Agraylea electroscientia sp. nov., Triplectides palaeoslavicus sp. nov., and Leptocerus solifemella sp. nov.) from the Rovno amber (Upper Eocene, Ukraine) are described     

Towards a revision of the genus Halectinosoma (Copepoda, Harpacticoida, Ectinosomatidae): new species from the North Atlantic and Arctic regions

This paper contributes to a revision of the genus Halectinosoma . Four new species are described, based on examination of ectinosomatid material from localities in western Europe, eastern Canada and the Arctic. Halectinosoma mandibularis sp. nov. is distinguishable from other species by the reduced setation of the mouthparts and enlarged mandibular gnathobase. Halectinosoma latisetifera sp. nov. bears an affinity with H. cooperatum but is easily distinguished by the shape of the setae on the female fifth leg. A species previously erroneously ascribed to H. finmarchicum (Scott) by several authors is described here as Halectinosoma kliei sp. nov. Halectinosoma gothiceps (Giesbrecht) is redescribed and the closely related Halectinosoma paragothiceps sp. nov. is described and distinguished from H. gothiceps . It is considered likely that some previous records of H. gothiceps are in error.  © 2007 The Linnean Society of London, Zoological Journal of the Linnean Society , 2007, 149 , 453–475.     

Description, biology and conservation of a new species of Australian tree frog (Amphibia: Anura: Hylidae: Litoria) and an assessment of the remaining populations of Litoria genimaculata Horst, 1883: systematic and conservation implications of an unusual speciation event

The Australian populations of the green-eyed tree frog Litoria genimaculata consist of a northern and southern genetic lineage that meet in a mosaic contact zone comprising two independent areas of contact: one where the main ranges of the lineages overlap, and the second where a population of the southern lineage is isolated within the range of the northern lineage. A recent study failed to find significant reproductive isolation between the main ranges of the two lineages, despite deep genetic divergence, partial postzygotic isolation, and call differences. The study did, however, demonstrate rapid phenotypic divergence and speciation of the isolated population of the southern lineage from both the parapatric northern lineage and from the allopatric, but genetically similar, main range of the southern lineage. Herein, the isolated population of the southern lineage is described as a distinct species, Litoria myola sp. nov. , whereas the remainder of the southern lineage and the northern lineage are retained as a single, paraphyletic species, Litoria genimaculata . Resolving this unusual systematic situation demonstrates the value of using multiple lines of evidence in delimiting species. Litoria myola sp. nov. has a very small distribution and population size and warrants a Critically Endangered listing (B1, 2) under IUCN criteria. Threats and management recommendations are outlined, and the conservation of hybrid zones as areas of evolutionary novelty is discussed.  © 2007 The Linnean Society of London, Biological Journal of the Linnean Society , 2007, 91 , 549–563.     

SERPUKHOVIAN CONODONTS FROM NORTHERN SPAIN AND THEIR BIOSTRATIGRAPHIC APPLICATION

Abstract:  Conodont collections from late Viséan–early Bashkirian deposits include numerous elements related to the cosmopolitan species Gnathodus bilineatus (Roundy) in the Cantabrian Mountains. Arnsbergian beds yield the taxa Gnathodus bilineatus leonicus subsp. nov., G. millarensis sp. nov., G. truyolsi sp. nov. and Gnathodus sp. nov. A. Almost all are also found in limestones of similar age in the Pyrenees, and the G. truyolsi conodont Zone is defined for the upper Serpukhovian of the northern Iberian Peninsula. In addition, numerous references to the proposed taxa come from Austria, Eastern Europe, Northern Africa and Asian localities. The increase in gnathodid diversity and abundance in northern Spain is related to a local Arnsbergian drowning episode of the carbonate platform. G. truyolsi is possibly derived from G. b. bilineatus , and there is morphological convergence with Gnathodus kiensis Pazukhin.     

A species complex within the isopod genus Haploniscus (Crustacea: Malacostraca: Peracarida) from the Southern Ocean deep sea: a morphological and molecular approach

Seven new species of the genus Haploniscus from the deep Scotia and Weddell Seas are presented, combining morphological and molecular data (mitochondrial 16S rDNA and nuclear 18S rDNA). Haploniscus cassilatus sp. nov. , H. cucullus sp. nov. , H. weddellensis sp. nov. , H. procerus sp. nov. and H. kyrbasia sp. nov. are characterized by a prominent rostral process, the size and shape of which vary among species. The rostrum of H. microkorys sp. nov. is distinctly smaller than that of the former species, while H. nudifrons sp. nov. does not possess a rostrum. The status of the latter as separate species is obvious, owing to the stronger morphological differences. DNA was sequenced from three of the other five species. Genetic distances together with the more subtle morphological variation justify the erection of separate species. Overall morphological variations between these species are small yet noticeable and include, among others, the rostrum, the shape of the pleotelson and setation of pereopods. Our molecular data sets reveal detailed phylogenetic insights within the Haploniscus cucullus complex, supporting the monophyly of all species. We found p -distances of at least 0.0732 (16S rDNA) and 0.0140 (complete 18S rDNA) between pairs of species and show that both genes can be used as a marker for DNA taxonomy.  © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society , 2008, 152 , 655–706.     

Three new species of Heliotmpium (Boraginaceae) from the Horn of Afiica region

Heliotropium subspinosum sp. nov., from the coastal and subcoastal zones of Yemen, Oman and Somalia, is described and illustrated. This is a woody species with small leaves, and particularly the only 1–4–flowered inflorescences, the axes of which become subspinescent, are remarkable in the genus. H. laxum sp. nov., a slender shrublet from central Somalia, is described, and H. personatum sp. nov., a shrublet that is widespread and scattered, particularly on gypseous ground, in eastern Ethiopia, most parts of Somalia and in southern Yemen, is described and illustrated.     

A revision of the assassin spiders of the Eriauchenius gracilicollis group, a clade of spiders endemic to Madagascar (Araneae: Archaeidae)

An endemic group of Malagasy spiders (Araneae: Archaeidae: Eriauchenius ) called the gracilicollis group is revised. The monophyly and phylogenetic relationships of the gracilicollis group are tested based on morphological characters. Archaeid spiders of Madagascar have evolved varying degrees of elongation in the cephalic area. Historically, it was believed that the extremely elongated cephalic area had evolved only once. These morphological data support the monophyly of the gracilicollis group and suggest that the elongated cephalic area has evolved more than once. All 14 species from the gracilicollis group are described and keyed, of which nine are new species: Eriauchenius ambre sp. nov. , Eriauchenius anabohazo sp. nov. , Eriauchenius borimontsina sp. nov. , Eriauchenius griswoldi sp. nov. , Eriauchenius halambohitra sp. nov. , Eriauchenius lavatenda sp. nov. , Eriauchenius namoroka sp. nov. , Eriauchenius spiceri sp. nov. and Eriauchenius voronakely sp. nov . The morphology of the gracilicollis group is examined in detail and figures of the male and female genitalia are presented. The distributions of the gracilicollis group species are presented and discussed and higher species group relationships within the Archaeidae are discussed.  © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society , 2008, 152 , 255–296.     

New and little-known Komokiacea (Foraminifera) from the bathyal and abyssal Weddell Sea and adjacent areas

Based on samples from the south-east Atlantic and Southern Ocean collected during the ANDEEP III campaign we describe three new species, Ipoa pennata sp. nov., Septuma stellata sp. nov. and Skeletonia variabilis gen. et sp. nov. , of the enigmatic deep-sea foraminiferan superfamily Komokiacea. A further six species, Ipoa fragila Tendal & Hessler, 1977, Komokia multiramosa Tendal & Hessler, 1977, Normanina conferta (Norman, 1878), Septuma ocotillo Tendal & Hessler, 1977, S. brachyramosa Kamenskaya, 1993, and S. komokiformis Kamenskaya 1993, are redescribed. Together, these nine species occurred at 14 stations across the depth range 1549–4935 m. Normanina conferta was found at 11 stations (1579–4935 m); S. ocotillo (4526–4935 m), S. brachyramosa (1819–4730 m) and S. stellata (2603–4934 m) at six stations each; I. fragila (4649–4934 m) at five stations; K. multiramosa (4700–4935) and S. variabilis (4696–4932 m) at four stations each; I. pennata (4803–4934 m) at three stations and S. komokiformis (3103–4526 m) at two stations. Five species occur in both the North Atlantic Ocean and the Southern Ocean, suggesting that close faunal links exist between these areas. Three were first described from the North Pacific Ocean while others, including the three new species, are so far known only from the Southern Ocean.  © 2007 The Linnean Society of London, Zoological Journal of the Linnean Society , 2007, 151 , 219–251.     

A new species of Ceratozamia (Zamiaceae) from Tabasco and Chiapas, Mexico

Ceratozamia becerrae sp. nov. is described and illustrated. This species from Tabasco and Chiapas has affinity with C. miqueliana H. Wendl. from Veracruz and Chiapas, but differs in morphology and habit of leaves, leaflets, male and female strobili and trunk. Ceratozamia becerrae is considered part of the C. miqueliana species complex that includes C. miqueliana, C. euryphyllidia Vázq.Torres, Sabato & Stevenson and C. zoquorum Pérez-Farrera, Vovides & Iglesias. The geographical range of this species complex is southern Veracruz, Tabasco and northern Chiapas in tropical rain forests.  © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society , 2004, 146 , 123–128.

Phylogeny of the pollinating yucca moths, with revision of Mexican species (Tegeticula and Parategeticula; Lepidoptera, Prodoxidae)

The yucca moths ( Tegeticula and Parategeticula ; Lepidoptera, Prodoxidae) are well known for their obligate relationship as exclusive pollinators of yuccas. Revisionary work in recent years has revealed far higher species diversity than historically recognized, increasing the number of described species from four to 20. Based on field surveys in Mexico and examination of collections, we describe five additional species: T. californica Pellmyr sp. nov. , T. tehuacana Pellmyr & Balcázar-Lara sp. nov. , T. tambasi Pellmyr & Balcázar-Lara sp. nov., T. baja Pellmyr & Balcázar-Lara sp. nov. and P. ecdysiastica Pellmyr & Balcázar-Lara sp. nov . Tegeticula treculeanella Pellmyr is identified as a junior synonym of T. mexicana Bastida. A diagnostic key to the adults of all species of the T. yuccasella complex is provided. A phylogeny based on a 2104-bp segment of mitochondrial DNA (mtDNA) in the cytochrome oxidase I and II region supported monophyly of the two pollinator genera, and strongly supported monophyly of the 17 recognized species of the T. yuccasella complex. Most relationships are well supported, but some relationships within a recent and rapidly diversified group of 11 taxa are less robust, and in one case conflicts with a whole-genome data set (amplified fragment length polymorphism, AFLP). The current mtDNA-based analyses, together with previously published AFLP data, provide a robust phylogenetic foundation for future studies of life-history evolution and host interactions in one of the classical models of coevolution and obligate mutualism.  © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society , 2008, 152 , 297–314.     

Taxonomic revision of the tribe Hymenodictyeae (Rubiaceae, Cinchonoideae)

The palaeotropical tribe Hymenodictyeae Razafim. & B. Bremer, belonging to the otherwise predominantly Neotropical subfamily Cinchonoideae  s.s. (coffee family or Rubiaceae), is revised here. The tribe as presently circumscribed contains two genera, Hymenodictyon Wall. and Paracorynanthe Capuron ex J.-F. Leroy, and is distinct from the other Cinchonoideae tribes with capsular fruits in having stipules bearing large, deciduous colleters on the margins, valvate corolla aestivation, and lenticellate capsular fruits that contain elongate, bilaterally flattened, and accrescent placentae. We recognize 22 Hymenodictyon species, including four new species ( H. antakaranensis sp. nov. , H. epiphyticum sp. nov. , H. madagascaricum sp. nov. , and H. tsingy sp. nov. ), and the two described species of Paracorynanthe . Hymenodictyon is distinguished from its sister genus, Paracorynanthe , by simple or compound spicate, racemose or thyrsoid inflorescences and corolla lobes without any appendages, rather than compound umbelliform inflorescences and corolla lobes prolonged by ciliate appendages. A full taxonomic treatment, keys, and distribution maps of all recognized Hymenodictyon and Paracorynanthe species are provided. Five lectotypes and one neotype are designated. Finally, six Hymenodictyon species are illustrated for the first time.  © 2006 The Linnean Society of London, Botanical Journal of the Linnean Society , 2006, 152 , 331–386.     

Taxonomic revision, phylogenetic analysis, and biogeography of the bee genus Tropidopedia (Hymenoptera, Apidae, Tapinotaspidini)

Thirteen new species are proposed: T. carinata sp. nov. , T. caracicola sp. nov. , T. danunciae sp. nov. , T. duckeana sp. nov. , T. eliasi sp. nov. , T. flavolineata sp. nov. , T. friesei sp. nov. , T. japuraensis sp. nov. , T. nigrita sp. nov. , T. nigrocarinata sp. nov. , T. ornata sp. nov. , T. peruana sp. nov. and T. venezuelana sp. nov. Taxonomic notes are provided for another four species: Tropidopedia punctifrons (Smith, 1879) comb. nov. , T. pallidipennis (Friese, 1899) comb. nov. , T. seabrai (Michener & Moure, 1957) and T. arcuatilis (Vachal, 1909) comb. nov. , including designation of a lectotype for Tetrapedia arcuatilis Vachal. An identification key, illustrations for main diagnostic characters, and distributions maps for all species are provided. A phylogenetic analysis was carried out to evaluate the monophyly of Tropidopedia and its main species groups, as well as to position it among the related genera. Biogeographical patterns are discussed.  © 2007 The Linnean Society of London, Zoological Journal of the Linnean Society , 2007, 151 , 511–554.     

Revision of the genus Menippus Clark in Australia (Coleoptera: Chrysomelidae: Galerucinae)

Abstract  The genus Menippus is revised for Australia, with six species, three of which are new: M. cynicus Clark, M. darcyi sp. nov. , M. ewani sp. nov. , M. fugitivus (Lea), M. sufi sp. nov. and M. yulensis (Jacoby) comb. nov. (from Diorhabda Weise). Menippus yulensis was described from New Guinea. This species and M. darcyi were formerly confused in Australia with M. fugitivus , which is now considered endemic to Lord Howe Island. The species formerly considered M. fugitivus and protected under the Threatened Species Conservation Act, New South Wales, is now named M. darcyi . A key is provided for the Australian species of Menippus and a lectotype designated for M. yulensis . The composition of Menippus is discussed and three non-Australian species are transferred to this genus: M. inconspicua (Jacoby) comb. nov. (from Diorhabda Weise); M. laterimaculata (Jacoby) comb. nov. ; and M. marginipennis (Jacoby) comb. nov. (from Galerucella Crotch). A revised checklist of Menippus species is given. The recorded foodplants of Menippus are species of Celtis (Ulmaceae).
