Molecular phylogenetic evidence indicates that the octocoral family Alcyoniidae is highly polyphyletic, with genera distributed across Octocorallia in more than 10 separate clades. Most alcyoniid taxa belong to the large and poorly resolved Holaxonia–Alcyoniina clade of octocorals, but members of at least four genera of Alcyoniidae fall outside of that group. As a first step towards revision of the family, we describe a new genus, Parasphaerasclera
gen. n., and family, Parasphaerascleridae fam. n., of Alcyonacea to accommodate species of Eleutherobia Pütter, 1900 and Alcyonium Linnaeus, 1758 that have digitiform to digitate or lobate growth forms, completely lack sclerites in the polyps, and have radiates or spheroidal sclerites in the colony surface and interior. Parasphaerascleridae fam. n. constitutes a well-supported clade that is phylogenetically distinct from all other octocoral taxa. We also describe a new genus of Alcyoniidae, Sphaerasclera
gen. n., for a species of Eleutherobia with a unique capitate growth form. Sphaerasclera
gen. n. is a member of the Anthomastus–Corallium clade of octocorals, but is morphologically and genetically distinct from Anthomastus Verrill, 1878 and Paraminabea Williams & Alderslade, 1999, two similar but dimorphic genera of Alcyoniidae that are its sister taxa. In addition, we have re-assigned two species of Eleutherobia that have clavate to capitate growth forms, polyp sclerites arranged to form a collaret and points, and spindles in the colony interior to Alcyonium, a move that is supported by both morphological and molecular phylogenetic evidence. 相似文献

Based on the examination of newly collected material and additional specimens housed in Chinese collections, our knowledge of Gastroserica Brenske, 1897, is expanded. Here, seven new species are described, including habitus photographs and illustrations of the male genitalia: Gastroserica haoyui
sp. n. (China: Zhejiang Prov.), G. fengduana
sp. n. (China: Sichuan Prov.), G. wenzhui
sp. n. (China: Guangxi Prov.), G. damingshanica
sp. n. (from China: Guangxi Prov.), G. jinxiuensis
sp. n. (China: Guangxi Prov.), G. liboensis
sp. n. (China: Yunnan Prov.) and G. carolusi
sp. n. (Laos). Additionally, we provide a distribution map of the new taxa and new distribution records of the known taxa. 相似文献

Two new species of yellow-shouldered bats Sturnira Gray, 1842 (Chiroptera, Phyllostomidae) from Central America and western South America are described using molecular and morphological data. The two new species, which occur in Costa Rica and Panama and in western Ecuador, were previously confused with S. ludovici, and S. lilium and S. luisi, respectively. Sturnira now includes 22 described species, making it the most speciose genus in the Neotropical family Phyllostomidae. 相似文献

Three new Hagnagora Druce species (Geometridae, Larentiinae) are described: Hagnagora
richardi Brehm, sp. n. from Ecuador, Hagnagora
hedwigae Brehm, sp. n. from Ecuador, and Hagnagora
mirandahenrichae Brehm, sp. n. from Costa Rica. A checklist of taxa assigned to Hagnagora is provided. Hagnagora is provisionally divided into six clades: the anicata clade (6 species), the buckleyi clade (3 species), the croceitincta clade (3 species), the ephestris clade (3 species), the mortipax clade (4 species) and Hagnagora
subrosea (1 species). Two taxa are revived from synonymy: Hagnagora
catagrammina Druce, stat. rev. and Hagnagora
luteoradiata Thierry-Mieg, stat. rev. Two taxa are reinstated from subspecies to species level: Hagnagora
acothysta Schaus, stat. rev. and Hagnagora
jamaicensis Schaus, stat. rev. Four taxa are provisionally removed from Hagnagora: “Hagnagora” ignipennis, “Hagnagora” mesenata, “Hagnagora” vittata, and “Hagnagora” ceraria. After these changes, the genus Hagnagora now comprises 20 valid species. 相似文献

The ant genus Paratrechina is reexamined based on the discovery of two new species from Madagascar (P. ankarana
sp. n. and P. antsingy
sp. n.). Paratrechina kohli, a species known from central Africa, is transferred to Paratrechina from Prenolepis based on a new morphological interpretation of the genus and an updated morphological diagnosis of the genus is provided. This means that other than the widespread P. longicornis, whose origins remain uncertain, all Paratrechina are restricted either to the Afrotropical or Malagasy regions. It would also appear that of the five Paratrechina species now known, three are from dry forest habitats. With this reexamination of the genus, the possible origins of P. longicornis are discussed. A key to the genera of the Prenolepis genus-group is provided, as is a key to the workers of Paratrechina. In addition, we also designate a lectotype for Paratrechina kohli. 相似文献

A new genus and new species of the family Cletopsyllidae Huys & Willems, 1989 from deep-sea sediment in the Gulf of Mexico, are reported and fully described and illustrated. The new genus Pentacletopsyllus (type species: P. montagni
sp. n.) can be distinguished from the four known genera of the family by antennule segmentation, length ratio of first and second endopodal segments of P1, and armature pattern on P5 exopod. It also differs from its sister genera by the rostrum being bifid at the tip, third segment of the female antennule having a smooth posterior margin, the baseoendopod of P5 with biarticulate outer setophore bearing basal seta, and female caudal rami without lobate expansion. A revised key to species of the family Cletopsyllidae Huys & Willems, 1989 is provided. 相似文献

A new genus and species of cyst nematode, Vittatidera zeaphila, is described from Tennessee. The new genus is superficially similar to Cactodera but is distinguished from other cyst-forming taxa in having a persistent lateral field in females and cysts, persistent vulval lips covering a circumfenestrate vulva, and subventral gland nuclei of the female contained in a separate small lobe. Infective juveniles (J2) are distinguished from all previously described Cactodera spp. by the short stylet in the second-stage juvenile (14-17 μm); J2 of Cactodera spp. have stylets at least 18 μm long. The new species also is unusual in that the females produce large egg masses. Known hosts are corn and goosegrass. DNA analysis suggests that Vittatidera forms a separate group apart from other cyst-forming genera within Heteroderinae. 相似文献

McDiarmid et al. (1999) published the first part of their planned taxonomic catalog of the snakes of the world. Since then, several new python taxa have been described in both the scientific literature and non-peer-reviewed publications. This checklist evaluates the nomenclatural status of the names and discusses the taxonomic status of the new taxa, and aims to continue the work of McDiarmid et al. (1999) for the family Pythonidae, covering the period 1999 to 2010. Numerous new taxa are listed, and where appropriate recent synonymies are included and annotations are made. A checklist and a taxonomic identification key of valid taxa are provided. 相似文献

Staphylinidae (Rove Beetles) from northeastern North America deposited in the University of Guelph Insect Collection (Ontario, Canada) were curated from 2008-2010 by the first author. The identification of this material has resulted in the recognition of thirty-five new provincial or state records, six new Canadian records, one new record for the United States and two new records for eastern Canada. All records are for subfamilies other than Aleocharinae and Pselaphinae, which will be treated in future publications as collaborative projects. Range expansions of ten exotic species to additional provinces and states are reported. The known distributions of each species in northeastern North America are summarized and presented as maps, and those species with a distinctive habitus are illustrated with color photographs. Genitalia and/or secondary sexual characters are illustrated for those species currently only identifiable on the basis of dissected males. The majority of the new records are in groups that have been recently revised, demonstrating the importance of curation and local insect surveys to the understanding of biodiversity, even for taxa and areas considered 'relatively well-known'. 相似文献

Five new species belonging to the poorly known Neotropical doryctine parasitoid wasps genera Heerz Marsh (Heerz ecmahlasp. n. and Heerz macrophthalmasp. n.), Lissopsius Marsh (Lissopsius pacificussp. n. and Lissopsius jalisciensissp. n.) and Ondigus Braet, Barbalho & van Achterberg (Ondigus cuixmalensissp. n.) are described from the Chamela-Cuixmala Biosphere reserve in Jalisco, Mexico. Keys to the described species of the above three genera are provided. The phylogenetic placement of the examined taxa is investigated based on mitochondrial (COI) and nuclear (28S, 2(nd) and 3(rd) domain regions) DNA sequence data. 相似文献

A taxonomic assessment of four species of octocorals from the northeastern Pacific Ocean (British Columbia to California) is provided. Included here are a new species of clavulariid stolonifieran Cryptophyton, a new species of the nephtheid soft coral Gersemia, an undetermined species of soft coral in the genus Alcyonium that has been referred in the literature by several other names, and a new genus is named for a plexaurid sea fan originally described in the Indo-Pacific genus Euplexaura. Discussions are included that compare the species to related taxa, or provide revisionary assessments. 相似文献
