Nineteen species of abundant gastropods were collected at Robben Island, including introduced dune snails and European brown garden snails. They were identified using morphology and DNA barcoding. It was expected that the species recorded would be similar to those from the Cape peninsula, South Africa, but we were surprised to find some exceptions: the very abundant invasive mussel species in South Africa, the South American bisexual mussel (Semimytilus
algosus), and the beaded topshells (Oxystele
impervia) were not found on Robben Island. Possible explanations are presented for these differences. 相似文献

A comprehensive and updated summary of the literature and unpublished records contained in scientific collections on the helminth parasites of the elasmobranchs from Mexico is herein presented for the first time. At present, the helminth fauna associated with Elasmobranchii recorded in Mexico is composed of 132 (110 named species and 22 not assigned to species), which belong to 70 genera included in 27 families (plus 4 incertae sedis families of cestodes). These data represent 7.2% of the worldwide species richness. Platyhelminthes is the most widely represented, with 128 taxa: 94 of cestodes, 22 of monogeneans and 12 of trematodes; Nematoda and Annelida: Hirudinea are represented by only 2 taxa each. These records come from 54 localities, pertaining to 15 states; Baja California Sur (17 sampled localities) and Baja California (10), are the states with the highest species richness: 72 and 54 species, respectively. Up to now, 48 elasmobranch species have been recorded as hosts of helminths in Mexico; so, approximately 82% of sharks and 67% of rays distributed in Mexican waters lack helminthological studies. The present list provides the host, distribution (with geographical coordinates), site of infection, accession number in scientific collections, and references for the parasites. A host-parasite list is also provided. 相似文献

The Afrotropical Cynipoidea are represented by 306 described species and 54 genera in four families: Cynipidae, Figitidae, Liopteridae and Ibaliidae, the latter represented by a single introduced species. Seven of these genera are only represented by undescribed species in the region. Seven new genus-level synonymies, one genus resurrected from synonymy, 54 new combinations, one combination reinstated, and one new replacement name are presented. We provide identification keys to the families, subfamilies and genera of cynipoid wasps occurring in the Afrotropical region (Africa south of the Sahara, including Madagascar and southern Arabian Peninsula). Online interactive Lucid Phoenix and Lucid matrix keys are available at: http://www.waspweb.org/Cynipoidea/Keys/index.htm. An overview of the biology and checklists of species for each genus are provided. This paper constitutes the first contributory chapter to the book on Afrotropical Hymenoptera. 相似文献

We report 21 new species records for the Coleoptera fauna of New Brunswick, Canada, seven of which are new records for the Maritime provinces. Four species of Mycetophagidae (Litargus didesmus Say, Litargus tetrapilotus LeConte, Mycetophagus punctatus Say, and Mycetophagus quadriguttatus Müller) are newly reported for the province of New Brunswick. Litargus didesmus is newly recorded for the Maritime provinces. Seven species of Tetratomidae are added to the faunal list of New Brunswick: Eustrophus tomentosus Say, Penthe obliquata (Fabricius), and Tetratoma tessellata Melsheimer are new to New Brunswick: Hallomenus serricornis LeConte, Pisenus humeralis Kirby, Synstrophus repandus (Horn), and Tetratoma variegata Casey, which are newly recorded for New Brunswick and the Maritime provinces. Ten additional species of Melandryidae are reported from New Brunswick, of which Orchesia cultriformis Laliberté, Orchesia ovata Laliberté, Phloeotrya fusca (LeConte), Scotochroides antennatus Mank, Spilotus quadripustulatus (Melsheimer), Symphora flavicollis (Haldeman), Symphora rugosa (Haldeman), and Zilora hispida LeConte are new for the province, and Microscapha clavicornis LeConte and Zilora nuda Provancher are newly recorded for the Maritime provinces. In addition, we report numerous additional records for three species of Mycetophagidae and one species of Melandryidae previously recorded from New Brunswick that suggest these species are more widely distributed than previously known. Collection, habitat data, and distribution maps are presented for all these species. 相似文献

The mirine plant bug genus Paramiridius, previously known only from a single Taiwanese species, is reported from Indochinese Laos for the first time and redefined. Two additional species, Paramiridius
indochinensis and Paramiridius
laomontanus, are described as new to science. The female genitalic structures of the genus are documented for the first time. Habitus illustrations, figures of male genitalia, and key are provided for all three known Paramiridius species. 相似文献

Only three species belonging to the genus Ectomyelois Heinrich, 1956 are recorded from China, of which two species, Ectomyelois
bipectinalis
sp. n. and Ectomyelois
furvivena
sp. n. are described as new. We discuss the status of Ectomyelois that has been treated as a junior synonym by previous authors; we treat it as a valid genus, revised status, based on characters of the venation and female genitalia. Photographs of the adults and illustrations of the genitalia are given, along with a key to the three known Chinese species. 相似文献

The record of Ostoma fraterna is the first recent record of this species from New Brunswick. Additional New Brunswick records of the thaneroclerine, Zenodosus sanguineus (Say), are given, indicting that this species is common and widespread in the province. One species of Cleridae, Cymatodera bicolor (Say),is newly reported from New Brunswick, and the adventive Thanasimus formicarius Linnaeus is newly recorded from Nova Scotia and the Maritime provinces. Attalus morulus (LeConte) and Dolichosoma foveicolle (Kirby), family Melyridae, are reported for the first time for New Brunswick and the Maritime provinces.

The cushion–star Parvulastra
exigua (Lamarck, 1816) is a widely distributed member of the temperate intertidal fauna in the southern hemisphere. In South Africa, it occurs in sympatry with the endemic Parvulastra
dyscrita (Clark, 1923), the two species being differentiated predominantly by gonopore placement. Several recent studies have suggested that there may be additional cryptic species within the Parvulastra
exigua complex in South Africa, based variously on color morphology, genetic evidence and the differential placement of the gonopores. This paper attempts to resolve whether one or more species are represented within Parvulastra
exigua. A total of 346 Parvulastra
exigua and 8 Parvulastra
dyscrita were collected from sites on the west and south–west coasts of South Africa; morphological, anatomical and genetic analyses were performed to determine whether cryptic species and/or Parvulastra
exigua specimens with aboral gonopores were present. Results show that neither cryptic species nor Parvulastra
exigua specimens with aboral gonopores occur at these sites. This study thus refutes previous claims of the existence of aboral gonopores in South African Parvulastra
exigua, and suggests that a single species is represented. The distinction between Parvulastra
exigua and Parvulastra
dyscrita is also confirmed, and features separating these two species are clarified and documented. 相似文献
