Truyolsodontos estauni n. gen., n. sp., Truyolsodontidae,a new family of lamniform sharks from the Cenomanian of northern Spain

Truyolsodontos estauni n. gen., n. sp. is described based on fossil teeth from the middle and upper Cenomanian of northern Spain. The species Protoscyliorhinus magnusLandemaine, 1991 is withdrawn from the genus Protoscyliorhinus and placed in this new one. For the new genus, the new family Truyolsodontidae is proposed.     

Bisbalia vossi n. g., n. sp. (Nematoda: Onchocercidae), a filarial worm from a geomyoid rodent,Heteromys anomalus,in Venezuela

Bisbalia vossi n. g., n. sp. is described from Heteromys anomalus (Rodentia: Geomyoidea: Heteromyidae) in northern Venezuela (Aragua). The filariae were found in a membranous pocket in the pleural cavity, and almost all had ingested red blood cells of their host. The morphology of this onchocercine species is highly evolved (advanced reduction of head and caudal papillae; short undivided oesophagus). Its very short microfilariae (60 m) and the shape of the tail of the female (two terminal median pairs of bosses) suggest that this species could be derived from Ackertia Vaz, 1934, a South American genus parasitic in caviomorph rodents which is related to the Dipetalonema-line, but Ackertia has several pairs of precloacal papillae, which are absent in the new genus. In North America, where the geomyoid rodents originated and diversified, the two previously described filarial species differ from this new material and show affinities with Old World bat parasites (Litomosa van Beneden, 1871).     

Pleurambus strongylus n. gen., n. sp. (Coleoptera: Belidae) in Dominican amber

A new genus and species of belid weevils, Pleurambus strongylus Poinar and Legalov, n. gen., n. sp. (Coleoptera: Belidae) in the tribe Allocorynini is described from Dominican amber. Belid fossils are quite rare and the new species is the first fossil member of the family from the Neotropics. This discovery suggests that belid diversity in Hispaniola during the Tertiary was higher than at present since no extant belids have been reported from the West Indies.http://www.zoobank.org/urn:lsid:zoobank.org:pub:DF79FF39-634D-4BD7-AD0B-F5FB3BBE1081     

Notogaeanemertes folzae gen. n., sp. n., an additional ecologically restricted hoplonemertean from New Zealand

Notogaeanemertes folzae gen. n., sp. n., a monoecious and ovoviviparous hoplonemertean, is described from the supra-littoral at Kaikoura, New Zealand. It shares more characters with group I terrestrial nemerteans than with group II which brings into question the significance of certain features in the systematics of semiterrestrial/terrestrial nemerteans.     

Bicalcasura maculata n. gen., n. sp. (Curculionoidea: Dryophthoridae) with a list of weevils described from Dominican amber

A new genus and species, Bicalcasura maculata n. gen., n. sp. (Coleoptera: Curculionoidea: Rhynchophorinae: Dryophthoridae) is described from Dominican amber as the first fossil member of the Tribe Diocalandrini. The new genus is characterised by procoxae located in the middle of the prothorax; a thick, short and strongly curved rostrum with the scape not reaching the pronotum; a weak extension of the rostrum in respect to the antennal attachment; slightly elongated fifth ventrite; narrow (not bilobed) third tarsomere and a pair of apical spurs on the protibiae. This set of characters separates the fossil from the extant genus Diocalandra Faust, 1894, the only other member of this tribe. A list of weevils (Curculionoidea) described from Dominican amber is included.

Pseudomoraria triglavensis gen. n., sp. n. (Copepoda,Harpacticoida) from a high-alpine reservoir in Slovenia

Numerous specimens of Pseudomoraria triglavensis gen.n., sp.n. were collected from small, high-alpine, reservoir Moilec. The reservoir is situated in the centre of Triglav national park (NW Slovenia) at an altitude of 1690 m. The new genus differs from related genera Moraria, Morariopsis and Paramorariopsis by the reduced articulation of exopodites and endopodites in both sexes. It also differs from Moraria by possessing sexually dimorphic furcal rami. Detail taxonomic differences between these related genera and their ecology are discussed.     

Helicoductus thulakoceras n. g., n. sp. (Cestoda: Hymenolepididae) parasite de Charadrius marginatus (Aves: Charadrii) d'Afrique du Sud

The authors describe and illustrate Helicoductus thulakoceras n. g., n. sp., a parasite of Charadrius marginatus (Aves: Charadrii) from South Africa. This hymenolepidid cestode is 1.5-3 mm long, with a rostellum armed with 10 diorchoid hooks 75-80 m long (mean 77 m) and anomalous terminal genital ducts. One spine (10-15 m long) is inserted at the ventral extremity of the male genital pouch. An invaginated cirrus is absent. A non-retractable and non-invaginable external tube, 25-30 × 4-2.5 m, appears as a spiral, sclerotinised, spinous canal, which is non-retractable, non-invaginable and directed dorso-ventrally from the genital pouch to a second ventral canal parallel with the male genital pouch; the second canal is thin and spine-like (15-20 × 1.5 m) with a thick hyaline muff. These peculiar anatomical structures are discussed. They are considered to justify the erection of a new genus.     

Katatopygia gen. n., a monophyletic branch segregated from Boletina (Diptera, Mycetophilidae)

The genus Katatopygia gen. n. is proposed for the Boletina erythropyga/punctus-group that was first introduced by Garrett (1924, 1925) and currently comprises eight described species. Molecular studies have strongly indicated that this group forms a monophyletic sister-group to a clade consisting of all other Boletina, Coelosia and Gnoriste, and its monophyly is supported by morphological data as well. The new genus includes the following species: Katatopygia antoma (Garrett, 1924), comb. n., Katatopygia antica (Garrett, 1924), comb. n., Katatopygia erythropyga (Holmgren, 1883), comb. n.,Katatopygia hissarica (Zaitzev & Polevoi, 2002), comb. n., Katatopygia magna (Garrett, 1925), comb. n., Katatopygia laticauda (Saigusa, 1968), comb. n., Katatopygia neoerythropyga (Zaitzev & Polevoi, 2002), comb. n. andKatatopygia sahlbergi (Lundström, 1906), comb. n., all transferred from Boletina. Katatopygia sahlbergi is found to be a senior synonym of Boletina punctus Garrett, 1925, syn. n. A phylogeny based on morphological data and using parsimony analysis yielded four most parsimonious trees where the new genus is retrieved as monophyletic with high support. Katatopygia neoerythropyga is found to be the sister-taxon to all other species that form two clades, one with Katatopygia sahlbergi-like species and one with Katatopygia erythropyga-like species. A key to males of Katatopygia is provided.     

Iranotrichia gen. n., a new genus of Scenopinidae (Diptera) from Iran, with a key to window fly genera of the world

An unusual new genus of Scenopinidae, Iranotrichia gen. n., comprising two newly discovered species (Iranotrichia insolita sp. n. and Iranotrichia nigra sp. n.), is described from Iran. Iranotrichia gen. n. are scenopinine window flies with a habitus reminiscent of certain bee fly genera (Bombyliidae), based on colouration and elongate mouthparts and antennae. The phylogenetic placement of this distinctive new genus is discussed and a dichotomous key to world genera is presented. The genus name Kelseyana nom. n. is proposed to replace Caenoneura Kröber, 1924, which was found to be preoccupied by Thomson (1870: 270) (Hymenoptera) and Kirby (1890: 136) (Odonata).     

Thermopsis thermophila n. gen. n. sp. from hot springs in Nevada, U.S.A. (Crustacea, Ostracoda)

Thermopsis thermophila n. gen. n. sp., a new freshwater ostracod species is described from hot springs in Nevada, U.S.A. The animals were collected within a temperature range of 40–55°C. The new genus belongs to the Ostracoda Podocopida Cypridoidea Cyprididae Cypridopsinae.     

Catoptinae subfam. n., a new subfamily of carpenter-moths (Lepidoptera,Cossidae)

The new subfamily of Cossidae; Catoptinae Yakovlev, subfam. n., well distinguished from other representatives of the family, is described. The new subfamily includes two genera: Catopta Staudinger, 1899 (type genus) and Chiangmaiana Kemal et Koçak, 2006. A catalogue of the subfamily is presented. One new synonym Catopta hyrcanus (Christoph, 1888) = Catopta brandti Bryk, 1947, syn. n., is established. The new subfamily has the following distinguishing features: short valvae; reduced processes of transtilla; vesica with numerous cornuti; pearshaped bursa copulatrix; and very short ductus bursae.     

Prozercon iranensis sp. n., a new species of Zerconidae (Acari: Mesostigmata) from Iran

A new species of pseudoscorpion of the genus Calocheiridius Beier &; Turk, Calocheiridius iranicus n. sp., is described from Markazi province, Iran. Illustrations and measurements of the species are given. http://www.zoobank.org/urn:lsid:zoobank.org:pub:06332B5C-D43A-4955-AB6C- 5847D10C2BAC     

Quadriacanthus aegypticus n. sp., a monogenean gill parasite from the Egyptian teleost Clarias lazera

Summary Quadriacanthus aegypticus n. sp., a monogenean from the gills of Clarias lazera inhabiting Nile delta waters in Egypt, is described. The genus Quadriacanthus Paperna, 1961 is reported for the first time in Egypt. Particular attention has been paid to the reproductive system, the digestive system, the anterior adhesive glands, the posterior body glands and haptoral sclerites. Possible functions of the different internal organs are discussed. The diagnosis of the genus Quadriacanthus is emended. ac]19840926     

Gall midges of the supertribe stomatosematidi (Diptera,Cecidomyiidae) in the Palaearctic region,with descriptions of new taxa from the late Eocene Rovno Amber. 2. The genera <Emphasis Type="Italic">Didactylomyia</Emphasis> and <Emphasis Type="Italic">Rovnodidactylomyia</Emphasis> gen. n.

One new genus (Rovnodidactylomyia Fedotova et Perkovsky, gen. n.) and four new species (Didactylomyia dlusskyi sp. n., Rovnodidactylomyia zosimovichi gen. n. et sp. n., R. sidorenkoi sp. n., and R. iconica sp. n.) are described from an amber sample of the late Eocene Period (Rovno District, Ukraine). Two species from a Baltic amber sample of the late Eocene Period, described earlier in the genus Bryocrypta, are attributed to the genus Rovnodidactylomyia (R. girafa (Meunier, 1904) comb. n. and R. capitosa (Meunier, 1904)). The first fossil species of the genus Didactylomyia is described for the first time; two contemporary Palaearctic species are recorded. Keys to the species of the genus Didactylomyia are given.     

Kritskyia moraveci n. g., n. sp. (Monogenea: Dactylogyridae) from the urinary bladder and ureters of Rhamdia quelen (Quoy & Gaimard, 1824) (Pisces: Pimelodidae) in Brazil

Kritskyia n. g. is proposed for K. moraveci n. sp. from the urinary bladder and ureters of Rhamdia quelen (Quoy & Gaimard, 1824), a pimelodid fish from the reservoir of the Hydroelectric Power Station of Passo Fundo, Rio Grande do Sul State, Brazil. The new genus is most closely related to Acolpenteron Fischthal & Allison, 1940, from which it differs by having a male copulatory complex composed of a coiled cirrus and a bipartite accessory piece, a sinistral vagina, and an antero-ventrally concave haptor which possesses 14 ventrally directed marginal hooks, but lacks an anterior rim and 4A hooks.Research fellow Conselho Nacional de Desenvolvimento Científico e Tecnológico, CNPq, Brasil.     

Platyamoeba stenopodia. n. g., n. sp., a Freshwater Amoeba*

SYNOPSIS. Platyamoeba stenopodia n. g., n. sp., isolated from a lake in Alabama, is an amoeba with flattened form, usually more than 2.5 × as long as broad, the anterior half hyaline and the posterior half granular, with a single vesiculate nucleus at the posterior edge of the hyaline region. It forms a transitory floating stage with slender, hyaline pseudopods. Its cyst is spherical, uninucleate, with a smooth inner wall and a thinner, closely applied outer wall, which is often slightly wrinkled. Length of locomotive amoeba 15–36 μ diameter of cyst 7–11.5 μ Reproduction by binary fission with mesomitotic nuclear division, the nuclear membrane disappearing in prophase. The genus Platyamoeba is erected for amoebae including this organism; the type species is P. placida.     

Elaeolenchus parthenonema n. g., n. sp. (Nematoda: Sphaerularioidea: Anandranematidae n. fam.) parasitic in the palm-pollinating weevil Elaeidobius kamerunicus Faust,with a phylogenetic synopsis of the Sphaerularioidea Lubbock, 1861

A new nematode, Elaeolenchus parthenonema n. g., n. sp., is described from the palm-pollinating weevil Elaeidobius kamerunicus Faust. The new genus is placed in the Anandranematidae n. fam., which, together with the genus Anandranema Poinar et al., 1993, is characterised by nematodes having only a single autotokous generation in the insect host. This is the first report of a member of this superfamily reproducing only parthenogenetically. The development of E. parthenonema and its effect on the weevil host is discussed, along with a phylogenetic synopsis of the families of the Sphaerularioidea Lubbock 1861. The Beddingiidae n. fam. is proposed for Beddingia Blinova & Korenchenko, 1986, comprising the original Deladenus parasites of Hymenoptera that possess both free-living and parasitic amphimictic generations in their life-cycles. This family is considered to have the most primitive type of development in the superfamily.     

Lepidotrachelophyllum fornicis,n. g., n. sp., a Ciliate with an External Layer of Organic Scales (Ciliophora,Litostomatea, Haptoria)1

Lepidotrachelophyllum fornicis n. g., n. sp. was discovered in White Lake, Ontario, Canada, under winter ice. The genus is Trachelophyllum-like, being highly flattened, elongate, and very extensible. The major feature that separates it from other genera in the family Trachelophyllidae is the presence of a dense layer of organic scales which covers the exterior of the cell and through which the cilia emerge. The scales are composed of filamentous material which is organized as an ovoid structure. The “rim” of the baseplate is formed of interwoven filaments. The baseplate is broken by circular or polygonal apertures. The same filaments form an arched superstructure broken by even larger, less regular apertures.     

Pseudonotohymena antarctica n. g., n. sp. (Ciliophora,Hypotricha), a New Species from Antarctic Soil

A new soil ciliate, Pseudonotohymena antarctica n. g., n. sp., from King George Island, Antarctica, is described based on live observation, protargol impregnation, and its 18S rRNA gene. The new genus Pseudonotohymena is morphologically similar to the genus Notohymena Blatterer and Foissner 1988 in the following characteristics: 18 fronto‐ventral‐transverse cirri, a flexible body, undulating membranes, dorsomarginal kineties, and the number of cirri in the marginal rows. However, Pseudonotohymena differs from Notohymena particularly in the dorsal ciliature, that is, in possessing a nonfragmented dorsal kinety (vs. fragmented). In addition, the molecular phylogenetic relationship of the new species differs from that of Notohymena species. On the basis of the morphological features, the genetic data, and morphogenesis, we establish P. antarctica n. g., n. sp. In addition, the cyst morphology of this species is described.
