Dorymenia troncosoi sp. nov. (Mollusca Solenogastres: Proneomeniidae), a new species from the South Shetland Islands (Antarctica)

During the Spanish oceanographic expedition BENTART '95, carried out in Antarctic waters off Livingston Island (South Shetland Islands), five small specimens of a new species of Solenogastres-Cavibelonia, Dorymenia troncosoi sp. nov., were collected at a depth of 65–240 m on a silt bottom. The species is characterized by the presence of a pallial cavity with four pouches (a dorsal, two lateral and a ventral pouch), seminal receptacles that open into the spawning ducts through a short duct, radula having 9–11 teeth per row (1 central and 4–5 lateral, all the same size), the end of the copulatory spicules having a cross-section in the shape of a four-pointed star, and abdominal spicules present. These characteristics separate this species from other species of the genus, particularly from Dorymenia profunda, which is the most similar. Received: 9 April 1998 / Accepted: 12 June 1998     

Revision of the Genus Paratylenchus Micoletzky, 1922, and Descriptions of New Species. Part I of 3 Parts

A revision of part of the genus Paratylenchus is reported covering those species with stylets averaging < 22 μm. Thirteen new species are described and further observations are given on the morphology and relationships of nine other species. Paratylenchus gahriciis transferred to the genus Hemicriconemoides. This article is the first of three parts: the second will treat Paratylenchus spp. with stylets averaging 24-40 μm (and include a key to the species described in parts 1 and2), the third will include species with stylets >40μm, respectively.     

A generic revision of the Dorvilleidae (Polychaeta), with six new species from the deep North Pacific

PETER A. JUMARS
The Dorvilleidae are divided into eight genera: Dorvillea, Schistomeringos (new name), Protodorvillea, Meiodorvillea (new genus), Exallopus (new genus), Ophryotrocha, Parophryotrocha , and Apophryotrocha (new genus). Periodic maxillary replacement is found to occur in a manner which makes many often cited maxillary characters taxonomically unreliable. Therefore, the pharyngeal characters of all the type-species are redescribed or newly described. The discovery of new forms and the present interpretation of hard jaw parts permit construction of a phylogenetic scheme with Dorvillea as the most primitive genus containing living species. Suggestions are given for the advantageous use of the phenomenon of maxillary replacement in autecoiogical investigation.
Evidence is presented against the cosmopolitan distribution of Schistomeringos rudolphi , a species often noted in nearshore pollution studies. Newly described species are Dorvillea batia, Schistomeringos mediofurca, Meiodorvillea apalpata, Exallopus cropion, Ophryotrocha profunda , and Apophryotrocha mutabiliseta , all from the deep North Pacific. A key to the genera is provided, as are listings of all the known species within each genus.     

A new species of the genus Microbunodon (Anthracotheriidae, Artiodactyla) from the Miocene of Pakistan: genus revision, phylogenetic relationships and palaeobiogeography

Lihoreau, F., Blondel, C., Barry, J. & Brunet, M. (2004). A new species of the genus Microbunodon (Anthracotheriidae, Artiodactyla) from the Miocene of Pakistan: genus revision, phylogenetic relationships and palaeobiogeography. — Zoologica Scripta , 33 , 97–115.
New unpublished remains of small Anthracotheriinae are described. First, materials from the upper Oligocene (MP 30) locality of La Milloque, southwest France, permit a review of the species Microbunodon minimum . Thereafter, fossils from the middle and late Miocene of the Potwar Plateau, Pakistan are attributed to the European genus Microbunodon . Microbunodon milaensis sp. n. from the Nagri Formation (between 10.3 and 9.2 Ma), Pakistan, is described and the species M. silistrensis from the Lower Manchar Formation (between 16 and 15 Ma) and from the Chinji Formation (between 12.7 and 11.5 Ma), Pakistan, is reviewed. The new species represents the last occurrence of the subfamily Anthracotheriinae, around 9.3 Ma. Similar materials from the Bugti and Siwalik Hills were previously considered as a small Anthracotherium . Comparisons with M. minimum from the European late Oligocene lead to a complete revision of the genus and permit definition of a new set of characters, which separate Microbunodon from Anthracotherium . A cladistic analysis reconsiders phylogenetic relationships among Anthracotheriinae, separating an Anthracothema–Anthracotherium clade and an Anthracokeryx–Microbunodon clade. Microbunodon appears to stem from the Asian late Eocene–lower Oligocene genus Anthracokeryx . These results imply a new distribution of the genus Microbunodon showing exchanges between Europe and Asia during the late Oligocene and probably the lower Miocene.     

<Emphasis Type="Italic">Microrasbora</Emphasis> Annandale,a new genus record in China,with description of a new species (Teleostei: Cyprinidae)

A new species of genus Microrasbora Annandale (1918), M. microphthalma, is described from the Nanwan River, a tributary of the Ruili River, Irrawaddy drainage, in southwest Yunnan province, China. This new species is the first record of the genus Microrasbora in China. Microrasbora microphthalma can be distinguished from the other species of Microrasbora by the following combination of characters: 15–16 predorsal scales, eye diameter/head length 27–38%, eye diameter/interorbital width 70–93%, predorsal length/ standard length 60–68%, the preanal length/ standard length 65–71% and the origin of dorsal fin is posterior of that of the ventral fin. Xiao-Yong Chen and Jun-Xing Yang contributed equally to this paper.     

Rainforest understory beetles of the Neotropics, Mizotrechus Bates 1872, a generic synopsis with descriptions of new species from Central America and northern South America (Coleoptera, Carabidae, Perigonini)

Information on the single previously described species, Mizotrechus novemstriatus Bates 1872 (type locality: Brazil - Amazonas, Tefé), is updated and 17 new species for the genus from Nicaragua, Costa Rica, Panamá, Colombia, Venezuela, and Guyane are described. The species records in the literature and on determined specimens in some collections of Mizotrechus novemstriatus Bates from Central America are not that species; currently, Mizotrechus novemstriatus is known only from its type locality in Amazonian Brazil. For the new species described, their known general distributions are as follows: Mizotrechus batesisp. n. (Guyane), Mizotrechus bellorumsp. n. (Guyane), Mizotrechus bruleisp. n. (Guyane), Mizotrechus belevederesp. n. (Guyane), Mizotrechus costaricensissp. n. (Costa Rica), Mizotrechus dalensisp. n. (Guyane), Mizotrechus edithpiafaesp. n. (provenance unknown), Mizotrechus fortunensissp. n. (Panamá), Mizotrechus gorgona. sp. n. (Colombia), Mizotrechus grossussp. n. (Guyane), Mizotrechus jefesp. n. (Panamá), Mizotrechus marielaforetaesp. n. (Guyane), Mizotrechus minutussp. n. (Guyane), Mizotrechus neblinensissp. n. (Guyane, Venezuela), Mizotrechus poirierisp. n. (Guyane), and Mizotrechus woldaisp. n. (Panamá). Long-term use of flight intercept traps in Guyane provided so many new species that apparently the use of FITs is the way to collect adults of this taxon, previously known from very few specimens. Many more species of this genus can be expected to be discovered throughout the Neotropics; the present contribution is a preliminary synopsis with identification key and adult images of all known species. Likely numerous species are yet to be discovered throughout tropical climes.     

Eight new species of Marasmodes (Asteraceae,Anthemideae) from South Africa

During a stay at the Kirstenbosch Research Centre in Cape Town (South Africa), several groups of Asteraceae were studied. One of these was the genus Marasmodes (tribe Anthemideae). After a careful taxonomic study of additional material, including the first species described by A. P. de Candolle, the author has concluded that eight collections should be considered as new species. These new species are described and their relationships with the most similar species of the genus are discussed. © 2009 The Linnean Society of London, Botanical Journal of the Linnean Society, 2009, 159 , 330–342.     

Three new species of the genus Leucon Kröyer, 1846 (Crustacea: Cumacea) from the continental slope off Surinam

Three new, and apparently closely related, species of cumacean are described from the continental slope off Surinam: Leucon turgidulus sp.nov. from about 500 m depth, L. medius sp.nov. from about 1000m and about 1500m, and L.jonesi sp.nov from about 1500m and about 2000m. The species have not been found in extensive collections from other parts of the deep Atlantic. Leucon pallidus G.O. Sars, 1865 is the most closely comparable of the previously known members of the genus.     

Review of the genus Fontidessus Miller & Spangler, 2008 (Coleoptera,Dytiscidae, Hydroporinae,Bidessini) with description of four new species

The genus Fontidessus Miller & Spangler, 2008 (Coleoptera: Dytiscidae: Hydroporinae: Bidessini) is reviewed. The genus now includes seven species with three previously described, and four new species described here: F. microphthalmus Miller & Montano, sp. n.; F. bettae Miller & Montano, sp. n.; F. christineae Miller & Montano, sp. n., and F. aquarupe Miller & Montano, sp. n. Each species is diagnosed and described, including the previously known species, based on new specimens and new information. Habitus, male genitalia and other diagnostic features are illustrated for each species. A key to the seven species is provided. Fontidessus species are unique to hygropetric habitats in the Guiana Shield craton of northern South American.     

Doassansiopsis caldesiae sp. nov. and Doassansiopsis tomasii: two remarkable smut fungi from Cameroon

Three recent collections of Doassansiopsis from western Cameroon are assessed taxonomically. Doassansiopsis caldesiae M. Piatek & Vánky is described as a new species from infected leaves of Caldesia reniformis (D. Don) Makino. Its diagnostic characters are flat, nonthickened sori with spore balls as blackish, slightly elevated dots, more or less globoid spores, conspicuous cortical sterile cells and parasitism on Caldesia reniformis of family Alismataceae. The species is compared to another Doassansiopsis species on host plants belonging to family Alismataceae. Doassansiopsis tomasii Vánky is described from two localities on Nymphaea nouchali Burm.f. var. caerulea (Savigny) Verdc. (Nymphaeaceae), which represents the first report of this smut from Cameroon and western Africa. Similarities between this species and Doassansiopsis nymphaeae (Syd. & P. Syd.) Thirum. and D. ticonis M. Piepenbr. are outlined and the global distribution of the three taxa is mapped. The species concept in the genus Doassansiopsis is discussed, and a key to all known species of the genus is provided.     

Morphology and ecology of two new species of Polypleurum (Podostemaceae) from Kerala, India

 Two new species of the Asiatic genus Polypleurum (Podostemaceae – Podostemoideae), Polypleurum prostratum and Polypleurum disciforme from Kerala, India are described. They differ in the shape of the thalloid plant body from the other species of Polypleurum. A key to the species occurring in India is provided. Though sharing the habitat with some other species of the Podostemaceae, the new species inhabit special niches in the rocky riverbed. – The chemical components of the (hard) water in which they grow differ considerably from what is known from black water rivers of the New World. The results thus widen considerably our knowledge of the ecological needs of Podostemaceae. Received December 10, 2002; accepted January 10, 2003 Published online: March 31, 2003     

Descriptions of two new species of Vietomartyria Hashimoto & Mey (Lepidoptera, Micropterigidae) from South China, with reference to autapomorphies of the genus

Two new species of micropterigids, Vietomartyria nankunshana Hirowatari & Hashimoto sp. nov. and V. nanlingana Hirowatari & Jinbo sp. nov., are described from Nankunshan and Nanling (Guangdong, China), respectively. The genus Vietomartyria Hashimoto & Mey, 2000, which was originally established as a monotypic genus, is redefined based on the following autapomorphies shared by the three species: (i) the long basal stalk of each flagellomere; (ii) the many (>100) minute serrate projections near the gonopore of aedeagus; and (iii) the gonopore situated dorsally near the apex.     

Agra, arboreal beetles of Neotropical forests: mixta group, virgata group, and ohausi group systematics (Carabidae)

Abstract. This paper is the fifth in a series designed to cover taxono-mically all species-groups of the lebiine genus Agra , whose cumulative ranges extend from southernmost Texas to northernmost Argentina. The mixta, virgata, feisthameli and ohausi groups constitute Section Feisthameli of the genus, and a key to these groups is provided. The mixta group consists of two species which have a composite range extending from southeastern Brazil to middle Mexico; the virgata group consists of nine species which have a composite range extending from southeastern Brazil to Guatemala; and the ohausi group consists of four species which have a composite range restricted to southeastern Brazil. The speciose feisthameli group is covered in a separate paper.
Among the three groups in the present paper, eleven new species are described from the following type localities: perkinsorum (MEXICO, Nayarit, 17.6 km southwest of Compostela), vate (MEXICO, Veracruz, Los Tuxtlas, La Playa Escondida), nola (REPUBLIC OF PANAMA, Panama, Cerro Campana), cadabra (EQUADOR, Pichincha, 47 km south of Santo Domingo de los Colorados, Rio Palenque Station), chocha (WEST INDIES, Trinidad, Arima Valley), phainops (FRENCH GUIANA, Pariacabo), imaginis (BRAZIL, Goias, Jatahy), inca (PERU, Madre de Dios, Rio Tambopata Reserve, 30 km (air) southwest of Puerto Maldonado), itatiaya (BRAZIL, Rio de Janeiro, Parque Nacional Itatiaya), calamitas (BRAZIL, Bahia, Itamaraju), anthrax (BRAZIL, Espirito Santo, Parque Socretama). A dot map illustrates the range of each taxon.
Distribution and relationships are discussed in general, but detailed cladistic and biogeographic analysis is deferred until taxonomy of the four groups of Section Feisthameli is completed. Species distribution correspond to Pleistocene refuges suggested by other authors based on other groups and classes of organisms.     

New species of the genus Epistephium (Orchidaceae, Vanilloideae)

The morphological study of the herbarium material representing Epistephium (Orchidaceae, Vanilloideae) led to the discovery of two groups of specimens that significantly differ from all known species of the genus. The results of literature data study and of comparative analysis of those and other specimens suggest that these collections represent new taxa that we describe as E. garayi and E. kubiyuense. The distinguishing features of the species are indicated. As both new species are reported from Colombia (E. garayi, also from Guyana), the key for the determination of all Colombian representatives of the genus is included. Information on the ecology and distribution of newly described taxa is presented.     

<Emphasis Type="Italic">Lecomtedoxa plumosa</Emphasis> (Sapotaceae), a new tree species from Korup National Park,Cameroon

Summary   Lecomtedoxa plumosa Burgt (Sapotaceae), a new tree species from the southern part of Korup National Park in Cameroon, is described and illustrated. The flowers show the characteristics of the genus Lecomtedoxa: for example the staminodes are free and placed alternately to the stamens and corolla lobes. The leaves of the new species are clearly different from other Lecomtedoxa spp., but they look similar to the leaves of Gluema ivorensis, especially to those of the collections from Cameroon. In total 26 trees ≥ 10 cm dbh were found. The largest trees found were 36 m high and 74 cm dbh. The trees grow in primary rain forest, in clusters of up to 10 trees on 2 ha, mixed with many other tree species. The seed dispersal is ballistic. The conservation status of the species is assessed as Endangered, EN D.     

The genus Unixenus Jones, 1944 (Diplopoda, Penicillata, Polyxenida) in Australia

The penicillate genus Unixenus Jones, 1944 is widespread, with species found in Africa, Madagascar, India and Australia. Each of the two Australian species was originally described from single samples from Western Australia. In this study, collections of Penicillata from museums in all states of Australia were examined to provide further details of the two described species, to revise the diagnoses for both the genus and the species, and to better understand the distribution of the two species in Australia. In addition, two new species Unixenus karajinensissp. n. and Unixenus corticolussp. n. are described.     

Pselaphotumulus,a new genus of pselaphine endemic to New Zealand (Coleoptera: Staphylinidae: Pselaphinae: Pselaphitae)

ABSTRACT

Pselaphotumulus Owens and Carlton, gen. nov., is described as the sixth genus in the tribe Pselaphini known from New Zealand. Three new species are described: Pselaphotumulus aorerei, sp. nov., Pselaphotumulus dubius, sp. nov. and Pselaphotumulus unus, sp. nov.. Three species, Pselaphus cavelli (Broun 1893), Pselaphus oviceps (Broun 1917) and Pselaphus urquharti (Broun 1917) are transferred to Pselaphotumulus, nov. combs. Lectotypes from type series in the New Zealand Broun Collection (Natural History Museum, London) are designated for these three species. Habitus photographs, distributional maps and line drawings of diagnostic characters are provided for each species. A key to species is provided. Searches of museum collections have not yielded representatives outside of New Zealand, suggesting that this is the first endemic genus in the tribe Pselaphini described from the New Zealand’s main islands, specifically, the South Island. Pselaphotumulus species exhibit restricted distribution patterns that approximately coincide with the Pacific/Indo Australian Plate boundary.
