New species and new data on Protrinemuridae and Nicoletiidae (Zygentoma) from Eastern Asia and Pacific islands

Four new genera and eleven new species of Zygentoma thysanurans (families Protrinemuridae and Nicoletiidae) are described and some faunistic novelties reported from Oriental and Australian Regions, viz.: Protrinemura leclerci n. sp., from northern Thailand, Protrinemurella allacrotelsoides n. gen. n. sp., from southern Thailand, and Protrinemuroides celebensis n. gen. n. sp., from the Celebes islands (Protrinemuridae), Lepidospora (L.) digitata n. sp., from northern Thailand, L. (L.) deharvengi n. sp., from the Celebes, and Pseudobrinckina anempodiata n. gen. n. sp., from northern Thailand (Nicoletiidae: Coletiniinae), Gastrotheus (G.) papuanus n. sp., from Papua-New Guinea (Nicoletiidae: Atelurinae), and Metrinura celebensis n. sp., from the Celebes, Trinemurodes anomalocoxa n. sp., from southern Thailand, T. bedosae n. sp., from northern Thailand, and Allotrinemurodes thai n.gen. n. sp., from northern Thailand (Nicoletiidae: Subnicoletiinae). Bharatatelura malabarica Mendes is reported for the first time off the Indian sub-continent (in Suva). Proatelura jacobsoni Silvestri is recorded in Macao (southern China) and in the Moluccas islands and notes are presented on its male sex. Gastrotheus (Lasiotheus) nanus (Escherich) is found for the very first time in Macao, in Cook islands and in Niue. Identification keys are provided to Protrinemuridae genera and to species of Trinemurodes, and modifications are suggested to previously presented keys to Nicoletiidae genera and to Lepidospora and Metrinura species.     

Four new Psocoptera from Lebanese amber (Insecta: Psocomorpha: Trogiomorpha)

Four new trogiomorphan Psocoptera are described from the Lower Cretaceous Lebanese amber, viz. Bcharreglaris amunobi n. gen., n. sp., Setoglaris reemae n.gen., n. sp., Libanoglaris chehabi n.sp., and Libanoglaris randatae n. sp. These discoveries show that the Lower Cretaceous biodiversity of the Trogiomorpha was very high.     

Two new genera and twelve new species of Anthuridea (Crustacea: Isopoda) from off the West Coast of New Zealand

Abstract

From the shelf and upper slope off the West Coast of the South Island of New Zealand, the following new taxa of Isopoda Anthuridea (Crustacea) are described: Kupellonura proberti n. sp. (Hyssuridae); Quantanthura pacifica n. sp., Haliophasma platytelson n. sp. and H. novaezelandiae n. sp. (Anthuridae) Albanthura stenodactyla n. gen. et sp., A. rotunduropus n. sp., Bullowanthura crebrui n. sp., Leptanthura tmncatitelson n. sp., L. exilis n. sp., L. profundicola n. sp., Paranthura longa n. sp., and Psittanthura egregia n. gen. et sp. (Paranthuridae). Most of these are blind, unpigmented species, adapted to life in deep water. Albanthura n. gen. is blind, has a single telsonic statocyst, short flagella of the antennae, a maxilliped with 3 palpal articles, and a triangular carpus on pereopods 4 to 7. Psittanthura n. gen. is also blind, with very unusual, enlarged subchelae of pereopods 1 and 2, a large, rectangular telson with a single statocyst; the maxillipedal palp is composed of 1 large and 1 small, distal article; a mandibular palp is absent.     

Entodiniomorph Ciliates from the Stomach of Hippopotamus amphibius, with Descriptions of Two New Genera and Three New Species

Entodiniomorph ciliates, belonging to the family Cycloposthiidae, are described from the stomach contents of Hippopotamus amphibius. Monoposthium acanthum gen. n., sp. n., with typical cycloposthiid structure, differs from other genera in having only 1 caudalium. Parentodinium gen. n., represented by P. africanum sp. n. and P. ostrea sp. n., although superficially resembling Entodinium, is considered to be a relatively unspecialized cycloposthiid.     

New and little known phalangopsinae (Orthoptera,Gryllidae): 7. Neotropical taxa of the tribes Paragryllini and Luzarini

Three new genera, one new subgenus, and 13 new species (Strogulomorpha separata sp. n., S. davidi sp. n., S. proxima sp. n., Luzarida lata sp. n., Luzara venado sp. n., L. sapani sp. n., Ucayacla pulchella gen. et sp. n., Peruzara atalaya gen. et sp. n., P. loreto sp. n., Amazonacla imitata gen. et sp. n., A. primitiva sp. n., Leptopsis (Leptopsis) ucayali sp. n., and L. (Aberracla subgen. n.) morona sp. n.) are described. The composition of the tribes Paragryllini and Luzarini and of the genera Luzarida Heb. and Luzara Walk is discussed. The new synonymies Luzarida Hebard, 1928 = Ecuazarida Nischk et Otte, 2000, syn. n.; Lerneca Walker, 1869 = Doposia Otte et Perez-Gelabert, 2009, syn. n.; Nemoricantor Desutter-Grandcolas et Hubbell, 1993 = Kumalorina Otte et Perez-Gelabert, 2009, syn. n. are given. The systematic position of some previously described species is corrected.     

New Paleocene large cassiduline foraminifera (Cassidinidae fam. nov., Miscellanacea) from Egypt and its phylogeny

Larger foraminifera of the Late Paleocene–Early Eocene lower slope to toe-of-slope deposits of the southern Galala, Egypt, are described. Sulcocassidina nakkadyi n. gen. et sp. (base) and Vacuolicassidella dakhlensis n. gen. et sp. (top) represent a phylogenetic line related to the family Cassidinidae (new family), superfamily Miscellanacea (new superfamily) in the latest Paleocene (shallow benthic zone 4) of the southern Galala, Egypt. In addition, Oscucassidella cassis n. gen. et sp., Pellatispiroides youssefi n. gen. et sp. and Chordcassidella ainshamsiana n. gen. et sp. are described and illustrated. Genus: Pomerolina n. gen. (Type species: Alveolina meandrina Carter, 1861, is newly erected and it belongs to Cassidinidae. In this family, the chambers are initially arranged streptospirally, whereas in later stages they are planispirally enrolled. Lateral chamberlets (retral process) are separated from the laminae by a passage and a marginal crest is added during growth.     

New and little known crickets of the subfamily Phalangopsinae (Orthoptera,Gryllidae): 6. Neotropical taxa of the tribes Phalangopsini and Paragryllini

Two new genera, ten new species, and two new subspecies: Uvaroviella izerskyi sp. n., U. morona sp. n., U. ucayali sp. n., U. pastaza sp. n., U. affinis sp. n., U. bolivia sp. n., U. bora atalaya subsp. n., Kevanacla orientalis contraria subsp. n., Peruacla solitaria gen. et sp. n., Ecuadoracla propria gen. et sp. n., Adelosgryllus spurius sp. n., and A. phaeocephalus sp. n. are described. The tribe Paragryllini is divided into three subtribes: Paragryllina Desutter, 1988 stat. n., Neoaclina Desutter, 1988 stat. n., and Strogulomorphina Desutter 1988, stat. n. The composition of the genera Uvaroviella Chop. and Neoacla Desutter is discussed. The species from Costa Rica and the Antilles are supposed to belong to these genera and subgenera. New synonymy [U. trinidadi Gorochov, 2007 = U. enodos Otte et Perez-Gelabert, 2009, syn. n. and N. multivenosa (Chopard, 1937) = Selvacla choreutes Otte, 2006, syn. n.] is proposed.     

Early Emsian ammonoids from the eastern Anti-Atlas (Morocco) and their succession

From 20 sections in the Tafilalt (eastern Anti-Atlas, Morocco), 13 early Emsian ammonoid species of the families Mimosphinctidae, Mimoceratidae, Teicherticeratidae, Mimagoniatitidae, and Auguritidae have been discovered. The following taxa are newly described:Chebbites n. gen.,Chebbites reisdorfi n. sp.,Chebbites undosus n. sp.,Gracilités maghribensis n. sp., Palaeogoniatitinae n. subfam.,Irdanites n. gen.,Irdanites kaufmanni n. sp.,Irdanites korni n. sp.,Lenzites gesinae n. sp.,Weyeroceras n. gen.,Weyeroceras angustus n. sp. In addition, specimens ofErbenoceras solitarium, Metabactrites formosus, andRuanites obliquecostatus are described and figured from Morocco for the first time. The ammonoid generaConvoluticeras, Erbenoceras, Mimosphinctes, Palaeogoniatites, Talenticeras, andTeicherticeras and the families Mimosphinctidae, Mimoceratidae, Teicherticeratidae, and Mimagoniatitidae are reviewed.Taskanites andLaganites are regarded as subjective junior synonyms ofConvoluticeras. In Morocco, the early Emsian ammonoid succession differs from what can be expected from a phylogenetic point of view. Several species belonging to different families of various phylogenetic stages appear within one stratigraphical unit. In contrast to previous opinions however,Gyroceratites laevis appears stratigraphically earlier thanMimagoniatites fecundus, which agrees in this case with the phylogenetic succession of the taxa. Stratigraphical data from early Emsian ammonoids are still insufficient as basis for a more detailed stratigraphical subdivision of the early Emsian.     

Expanding the molecular and morphological diversity of Apusomonadida,a deep-branching group of gliding bacterivorous protists

Apusomonads are cosmopolitan bacterivorous biflagellate protists usually gliding on freshwater and marine sediment or wet soils. These nanoflagellates form a sister lineage to opisthokonts and may have retained ancestral features helpful to understanding the early evolution of this large supergroup. Although molecular environmental analyses indicate that apusomonads are genetically diverse, few species have been described. Here, we morphologically characterize 11 new apusomonad strains. Based on molecular phylogenetic analyses of the rRNA gene operon, we describe four new strains of the known species Multimonas media, Podomonas capensis, Apusomonas proboscidea, and Apusomonas australiensis, and rename Thecamonas oxoniensis as Mylnikovia oxoniensis n. gen., n. comb. Additionally, we describe four new genera and six new species: Catacumbia lutetiensis n. gen. n. sp., Cavaliersmithia chaoae n. gen. n. sp., Singekia montserratensis n. gen. n. sp., Singekia franciliensis n. gen. n. sp., Karpovia croatica n. gen. n. sp., and Chelonemonas dolani n. sp. Our comparative analysis suggests that apusomonad ancestor was a fusiform biflagellate with a dorsal pellicle, a plastic ventral surface, and a sleeve covering the anterior flagellum, that thrived in marine, possibly oxygen-poor, environments. It likely had a complex cell cycle with dormant and multiple fission stages, and sex. Our results extend known apusomonad diversity, allow updating their taxonomy, and provide elements to understand early eukaryotic evolution.

The ecology and the biogeography of the species are briefly discussed.     

New Carboniferous brachiopod genera from Huai Bun Nak,North-east Thailand

Five new genera and species are described from brown silty mudstone near Huai Bun Nak, north-east Thailand. New taxa areProrugaria thailandica n. gen., n. sp. (Family Rugosochonetidae);Tuberculatella tubertella n.gen., n.sp. (Family Overtoniidae);Minispina alata n.gen., n.sp. (Family Marginiferidae);Aspinosella sinauris n.gen., n.sp. (Family Retariidae) andMucrospiriferinella undulosa n.gen., n.sp. (Family Xestotrematidae). The age is considered to be younger Carboniferous.     

New Genera and Species of ‘Giant’ Ostracods (Crustacea: Cyprididae) from Australia

Two new genera of giant ostracods Lacrimicypris n. gen. and Repandocypris n. gen. from Australia are described and eight new species:L. kumbar n. sp., R. austinensis n. sp., R. gleneagles n. sp., Mytilocypris coolcalalaya n. sp., Australocypris bennetti n. sp., A. beaumonti n. sp., A. mongerensis n. sp. and Caboncypris kondininensis n. sp. The number of known Australian genera and species of giant ostracods are now 6 and 21, respectively. Keys to genera and species are provided: all species can be distinguished using the hemipenis and male first leg. The usefulness of the bursa copulatrix as a species-level taxonomic character is highlighted. Most of the species described in this paper occur in salt lakes and existing ecological information on Western Australian species, as well as the distributions of all species, are summarized. Western Australia has a particularly rich halobiont fauna but current explanations relating richness of the halobiont fauna to the widespread occurrence of salt lakes appear incomplete. Australocypris bennetti is unusual in that it is frequently found at pH < 4. Its morphology differs slightly in acidic and alkaline waters.     

New species,new genera,and new records in Cerambycidae from Peru (Coleoptera)

Three new species and two new genera of longhorn beetles are described from Peru: Cosmoplatus polis n. sp. (Pteroplatini), Hemilocallia grishami n. gen., n. sp. (Calliini) and Arabela ramirezi n. gen., n. sp. (Hemilophini). Esmeralda laetifica Bates, 1869 (Prioninae), Stratone transversalis (Chevrolat, 1862) (Cerambycinae), Gymnocerina cratosomoides (Bates, 1862) (Lamiinae), and Trachysomus verrucosus (Olivier, 1795) (Lamiinae) are new records for Peru.     

New records,species, genera,and a new family of gastropods from hydrothermal vents and hydrocarbon seeps*

More than 100 species of gastropods from vent and seep localities around the world are reviewed, based on literature information and new material. The following new taxa are described (localities with parentheses, systematic position within brackets): Cantrainea macleani sp.n. (Louisiana Slope) [Turbinidae]; Fucaria striata gen. et sp.n. (Juan de Fuca Ridge area), Vetuloniaphalcata sp.n. (North Fiji Basin) [both Trochidae]; Protolira valvatoides gen. et sp.n. (Mid-Atlantic Ridge) [Skeneidae]; Ventsia tricarinata gen. et sp.n. (Lau Basin), Bruceiella globulus gen. et sp.n. (Lau Basin) [both tentatively in Skeneidae]; Melanodrymia brightae sp.n. (Juan de Fuca Ridge area), Pachydermia sculpta sp.n. (Lau Basin), Planorbidella gen.n., P. depressa sp.n. (Lau Basin), Ctenopelta porifera gen. et sp.n. (EPR 13°N)[Peltospiridae]; Helicrenion reticulatum gen. et sp.n. (Lau Basin), Lepfogyra inflata sp.n. (Lau Basin) [families unknown]; Desbruyeresia spinosa gen. et sp.n. (Lau Basin), D. cancellata sp.n.(Lau Basin), D. melanioides sp.n. (Lau Basin), Provanna buccinoides sp.n. (Lau Basin) [Provannidae]; Hyalogyra vitrinelloides sp.n. (Lau Basin), Hyalogyrina grasslei s p a (Guaymas Basin)[Hyalogyrinidae fam. n.], Xylodiscula major sp.n. (North Fiji Basin) [Xylodisculidae]. The external morphology of the soft parts [for Ifremeria and Alviniconcha (Provannidae) also the anatomy] is described for most of the taxa involved. Some features in the biology and distribution of the gastropod fauna are discussed. About half the fauna consists of species belonging to families or superfamilies endemic to this environment. One-fifth of the remaining species belong to taxa normally associated with biogenic substrates in the deep sea. Alviniconcha hessleri has previously been shown to harbour chemosynthetic bacteria in the gill; Ifremeria nautilei is here confirmed to do the same. Ctenopelta porifera, and Hirtopelta hirta are suspected to have such bacteria because of reduction of the alimentary system.

A new tribe, Palaeoerirhinini Legalov, n. tribe, two new genera, Cretotanaos Legalov, n. gen. (type species: Cretotanaosbontsaganensis n. sp.) (Curculionidae: Erirhininae) and Palaeoerirhinus Legalov, n. gen. (type species: Palaeoerirhinusponomarenkoi n. sp. (Brentidae Apioninae) and five new species, C. bontsaganensis Legalov, n. sp., P.latus Legalov, n. sp., P. thompsoni Legalov, n. sp., P. longirostris Legalov, n. sp. and P. ponomarenkoi Legalov, n. sp. from the Bon-Tsagaan locality (Mongolia, Cretaceous, Aptian) are described.http://zoobank.org/3D42DB5C-1841-46F1-A2A0-1034DDE10490     

Report on the Polycystididae (Rhabdocoela, Kalyptorhynchia) from Australia, with the Description of Twelve New Species and Six New Genera

Twelve new species of Polycystididae Graff, 1905 are described from the Australian east coast. Nine of them could not be placed in any of the existing genera, and therefore six new genera are erected. Alchoides n. gen. differs from all other polycystidid genera by the presence of a bundle of glands that opens into the distal part of the male atrium (accessory vesicle type V). Two species are included in the genus, A. alchoides n. sp. and A. dittmannae n. sp., which differ from each other in the shape of the stylet. Ametochus gehrkei n. gen n. sp. can be distinguished from other polycystidids by the presence of a prostate vesicle type III associated with a prostate stylet type III, combined with the presence of an accessory stylet type III, while a prostate stylet type II is lacking. Typical for Arrawarria inexpectata n. gen n. sp. is the combined presence of an armed cirrus with a prostate vesicle type II connected to a prostate stylet type II. Two species are assigned to the new genus Duplexostylus n. gen.: D. rowei n. sp. and D. winsori n. sp. These two species have two unique features: a prostate vesicle type IV directly connected to a prostate stylet type III and an asymmetrical septum that surrounds the proximal part of the male atrium. They can be distinguished from each other by differences in the detailed construction of their stylets. Two new species are placed in the new genus Stradorhynchus n. gen.: S. caecus n. sp. and S. terminalis n. sp. They have unpaired gonads and a prostate vesicle type IV connected to a prostate stylet type IV, which combination of characters makes them unique within the Polycystididae. The two species differ from each other in the shape and size of the stylet. Triaustrorhynchus armatus n. gen., n. sp. is the first species of the Polycystididae to have three types of stylet in the male atrium: a prostate stylet type II, a prostate stylet type III and an accessory stylet type III. Three new species could be placed in existing genera: Cincturorhynchus monaculeus n. sp., Paraustrorhynchus caligatus n. sp. and Polycystis australis n. sp. All three differ from their congeners in the form and dimensions of their stylets. All newly described species are discussed, giving their similarities and differences with resembling species. Austrorhynchus hawaiiensis Karling, 1977 is reported for the first time in Australia, and the Australian population is compared with populations from other regions. The presence of Gyratrix hermaphroditus Ehrenberg, 1831, one new species of Paulodora Marcus, 1948 and a new genus of Typhlopolycystidinae Evdonin, 1977 is mentioned.     

New acrodont lizards (Lacertilia) from the Middle Eocene of southern Mongolia

The problematic lizard family Changjiangosauridae, representatives of which inhabited Asia in the Early Paleogene, is discussed. Six new species of this group, including Acrodontopsis robustus gen. et sp. nov., Agamimus gracilis gen. et sp. nov., Graminisaurus interruptus gen. et sp. nov., Khaichinsaurus reshetovi gen. et sp. nov., Lavatisaurus elegans gen. et sp. nov., and Lentisaurus giganteus gen. et sp. nov., from the Middle Eocene of the Khaichin Uul 2 locality (southern Gobi, Mongolia) are described. It is shown that Changjiangosauridae are probably related to the Late Cretaceous Isodontosauridae and recent Uromastycidae; independent development of a number of dental features in different lineages of Acrodonta (Iguania) is corroborated.     

PERMIAN OSTRACODS FROM THE LERCARA FORMATION (MIDDLE TRIASSIC–CARNIAN?), SICILY,ITALY

Abstract: A rich, diverse Permian ostracod fauna has been recovered from the red and grey, laminated shales and quartz‐rich shales of the Triassic Lercara Formation. Forty‐seven species have been identified, 13 of which are newly described here; they belong to 26 genera of which three are new: Anahuacia lercaraensis sp. nov., Aurigerites siciliaensis sp. nov., Bairdia portellaensis sp. nov., Cristanaria? katyae sp. nov., Fabalicypris gruendeli sp. nov., Lethiersa salomonensis gen. et sp. nov., Lethiersia sinusoventralis gen. et sp. nov., Portella trapezoida gen. et sp. nov., Siciliella elongata gen. et sp. nov., Siciliella infernespinosa gen. et sp. nov., Siciliella prima gen. et sp. nov., Siciliella quadrata gen. et sp. nov., and Siciliella spinorobusta gen. et sp. nov. The assemblages contain or are composed of palaeopsychrospheric forms, which are regarded as index fossils for deep environments. The bathymetry of the different associations in life is evaluated.     

New Middle Permian insects from Salagou Formation of the Lodève Basin in southern France (Insecta: Pterygota)

Summary

New insects are described from the Middle Permian (Guadalupian) of Salagou Formation in the Lodève Basin (Languedoc region, France). Palaeopterans are represented by new odonatopterans viz. Huangiopterum lodevense n. gen., n. sp. and Huangiopterum species B, attributed to clade Panodonata (Huangiopteridae n. fam.), already recorded through the family Saxonagrionidae in the same formation, and a diaphanopterodean Martynovia cf. halli Beckemeyer 2004 (Martynoviidae) known from the Lower Permian of Oklahoma. Archaeorthopterans are supplemented by Bethouxia ariegensis n. gen., n. sp., Paralongzhua elongata n. gen., n. sp., Lodevolongzhua incompleta n. gen., n. sp., the caloneurodean Jarmiloptera mouralensis n. gen., n. sp., and a cnemidolestodean cf. Tococladus sp. (Tococladidae). Permophyllum rotundatum n. sp. (?Tettigoniidae) demonstrates the first presence of Orthoptera with wings probably mimicking Peltaspermales reproductive organs in Late Palaeozoic possibly analogous to the known crypsis of roachoid tegmina with pteridosperm pinnules. Frequent occurrence of hardly identifiable grylloblattid wing fragments support their significant role in term of abundance and diversity of the Permian faunas. New taxa based on wing venation pattern as Genera and species undetermined A, B (Liomopteridae), Permobaharellus salagousensis n. gen., n. sp. (family uncertain), Lodevophlebia reticulata n. gen., n. sp. (Sylvaphlebiidae), Oborella lodevensis n. sp. (Euryptilonidae), and Genus and species undetermined C, were described. Paoliida is represented by a paoliid gen. et sp. indet. and three anthracoptilids Strephocladus gandi n. sp., Strephocladus mouralensis n. sp., Lodevocladus subtilis n. gen., n. sp. The first record of miomopteran Palaeomantis sp. (Paleomanteidae) from Salagou Formation is presented. Acercarian insects are represented by the first record of Thripida and diverse new hemipterans, namely Euroscytina lutevanorum n. gen., n. sp. (Cicadomorpha: Scytinopteridae), Prosbole dio n. sp., Prosbole garrici n. sp., Pervestigia cf. veteris Becker-Migdisova 1961 (Prosbolidae), Archescytina species A (Paleorrhyncha: Archescytinidae) and Permopsyllidium lesclansis n. sp. (Sternorrhyncha: Psylloidea: Protopsyllidiidae). Entomofauna from the Salagou Formation demonstrate highly diverse insect communities with some taxa linked to early and late Permian ones known from assemblages in Euramerica and Russia, such as Obora (Czech Republic), Wellington Formation (Kansas and Oklahoma, USA), and Tshekarda (Ural, Russia).     

Two New Genera of Baetidae (Ephemeroptera; Insecta) from Madagascar

Two new genera of Baetidae (Ephemeroptera), Scutoptilum gen. n. and Echinopus gen. n., are described to accommodate three new species from Madagascar: Scutoptilum verrucosum sp. n., Echinopus giboni sp. n., Echinopus minutus sp. n.. They all share a unique apomorphy; they possess a subapico-transverse arc of long setae on the outer margin of femora. Scutoptilum presents important adaptations to fast flowing waters and mouthparts modified for scraping. Moreover, Scutoptilum shows an unusual general habitus with a prothorax broadly expanded laterally, forewing pads extremely developed and shape of the head subrectangular. Echinopus appears less derived and possesses more plesiomorphic features. Both genera are closely related to the Afrotropical genus Afroptilum and belong to the Centroptiloides complex.
