The Phlesirtes complex (Orthoptera,Tettigoniidae, Conocephalinae,Conocephalini) reviewed: integrating morphological,molecular, chromosomal and bioacoustic data

The tettigoniid genus Phlesirtes Bolivar and its allies are reviewed. Morphological, ecological and molecular data prompt the erection of the new genus Chortoscirtes gen.n. with type species Xiphidion meruense Sjöstedt. The genera Phlesirtes, Chortoscirtes, Karniella and Naskreckiella are characterized by morphological characters supported by molecular, acoustic, ecological and chromosomal data. Four species, Chortoscirtes pseudomeruensis sp.n. , C. masaicus sp.n. , C. puguensis sp.n. and C. serengeti sp.n. , are described from localities in northern and coastal Tanzania and one Karniella, K. crassicerca sp.n. , is described from Uganda. The following comb n. are proposed: Phlesirtes kibonotensis (Sjöstedt) and Phlesirtes kilimandjaricus (Sjöstedt). Subtribal status is proposed for the four investigated African genera. A key to the Chortoscirtes species is provided.     

Scaphidiidae (Coleoptera) of Fiji

Abstract

This paper describes 12 new species of Scaphidiidae from Fiji based on a collection made in October 1977 on the two main islands, Viti Levu and Vanua Levu. Three genera and 23 species are now known from Fiji: Baeocera Erichson (parallela n.sp., vanuana n.sp., plana n.sp., ovalis n.sp., kuscheli n.sp., gnava n.sp., ignobilis n.sp., kuscheliana n.sp., reducta n.sp., plus two species left unnamed); Scaphisoma Leach (kuscheli n.sp., liliputanum Löbl, distans Löbl, aequatum Löbl, zimmermani Löbl, debile n.sp., mucronatum n.sp., fijianum Löbl, alienum Löbl); and Scaphoxium Löbl (ventrale Löbl, malekulense Löbl, vitianum Löbl). Keys are given to genera and species.     

Ecological adaptations of grassland‐inhabiting flightless Orthoptera: Fulvoscirtes and Acanthoscirtes,two new genera of African Karniellina (Orthoptera,Tettigoniidae, Conocephalinae,Conocephalini)

Two new genera, Fulvoscirtes n.gen. and Acanthoscirtes n.gen. , are established within the subtribe Karniellina of Conocephalini. Fulvoscirtes is based on Xiphidion kilimandjaricum Sjöstedt, 1909 and Acanthoscirtes on Phlesirtes kevani Chopard from northern Kenya. The majority of Fulvoscirtes spp. are confined to open grasslands in the submontane zone of mountains. Fulvoscirtes contains eight species, seven of which are newly described in this paper. Three species and one subspecies occur on Mt Kilimanjaro. These are F. kilimandjaricum (Sjöstedt) constricted to the southern slopes, F. legumishera n.sp. confined to the northern side and F. sylvaticus n.sp. occurring on the western side of Kilimanjaro and on the eastern slopes of Mt Meru. Fulvoscirtes fulvus n.sp. is divided into two subspecies, F. fulvus fulvus n.ssp. found in the submontane zone of east Kilimanjaro and F. fulvus parensis n.ssp. in submontane to montane localities of the North and South Pare mountains. Fulvoscirtes fulvotaitensis n.sp. occurs in the Taita Hills of southern Kenya. Fulvoscirtes viridis n.sp. is described from savannah habitats between Mts Longido and Meru. Fulvoscirtes laticercus n.sp. is found in the Kenyan highlands, while the most southerly occurring species, Fulvoscirtes manyara n.sp. , is found on Mt Hanang and the Mbulu highlands of northwestern Tanzania. Acanthoscirtes contains three species, of which A. albostriatus n.sp. is described newly from savannah habitas of eastern Kilimanjaro. Information is given on the ecology and the acoustic behaviour of some of the species together with keys to the genera of the Karniellina and the species of Fulvoscirtes and Acanthoscirtes. The genera of Karniellina probably evolved at a time when grasslands spread in East Africa due to an increasing aridification of the climate. The earliest lineage, the genus Karniella, is adapted to more forested habitats while the majority of the genera of Karniellina prefer open grasslands. Major splits within Karniellina probably occurred with the emergence of savannah grasslands due to the ongoing fragmentation of forest habitats several millions years ago, but most species within the genera are geologically young, their radiation being boosted by climatic fluctuations of the past 1–2 Ma.     

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

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.     

First Report on Marine Microturbellarians from Hawaii

Karling, T. G. (Section of Invertebrate Zoology, Swedish Museum of Natural History, Stockholm, Sweden), Valeria Mack-Fira, and Jürgen Dörjes. First report on marine microturbellarians from Hawaii. Zool. Scripta 1 (6): 251–270, 1972.–The material presented here consists of: Cilionema hawaiiensis gen. et sp. n., Microvahine corallicola gen. et sp. n., Archiloa subtilis sp. n., Minona bistylifera sp. n., Duplominona kaneohei sp. n., Archimonocelis heljrichi sp. n., Ulelga variodentata sp. n., Notocelis gullmarensis maculata ssp. n., Cylindrcstoma monotrochum (Graff), Plagiostomum acoluthum Marcus, Gyratrix hermaphroditus Ehrenberg and Austrorhynchus pectatus Karling.

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

A new lowermost middle Cambrian (Series 3, Stage 5) faunule from Saxony (Germany) and its bearing on the tectonostratigraphic history of the Saxothuringian domain

The core of borehole 1209/78 west of Doberlug–Kirchhain and south of Herzberg in the Torgau–Doberlug Syncline records an atypical lower part of the Tröbitz Formation with thin limestone horizons. These limestone layers include the remains of a low to moderately diverse fauna with the trilobites Protolenus (Hupeolenus) bergstroemi n. sp., Cambrunicornia saxonica n. sp., Ornamentaspis? aff. todraensis Geyer 1990a, Calodiscus? n. sp., the remains of two undetermined olenelloid? and paradoxidid? species, at least two brachiopods (Trematobolus, undetermined acrotretoid), and one hyolith. The fauna clearly suggests a position in the lower Agdzian stage of the West Gondwana chronostratigraphic scheme and correlation with the lowermost to lower Middle Cambrian strata in regions such as the Moroccan Atlas ranges and northern Spain, so the assemblages represent the oldest Middle Cambrian fauna known from the Saxothuringian domain and reconfirm the palaeogeographic position in the Perigondwanan segment. The lithological differences of the fossiliferous cores from those of the typical Tröbitz Formation and the recorded high-energy conditions indicate high-frequency sea-level changes suggesting that this part of the succession may be a late stage of the subglobally recognizable eustatic sea-level fluctuations at the traditional Lower–Middle Cambrian boundary interval.     

Three new chironomids (Diptera: Chironomidae) from the New Zealand seashore

The adults of Telmatogeton mortoni n.sp. (Clunioninae) and Smittia reinga n.sp. and Smittia whangaroa n.sp. (Orthocladiinae), from the northern New Zealand seashore, are described and figured.     

Description of a new species of giant clam (Bivalvia: Tridacnidae) from Ningaloo Reef,Western Australia

A new species of giant clam from northern Australian coastal waters is distinguished principally on genetic evidence. Of Recent tridacnids, Tridacna ningaloo n. sp. is morphologically closest to the most widespread species in the Indo-Pacific, Tridacna maxima (Röding, 1798), yet genetically closest to the species pair T. squamosa Lamarck, 1819 plus T. crocea Lamarck, 1819. Genotype data are provided for the type material of T. ningaloo n. sp. The greatest significance of this new, cryptic species is that it casts doubt on the correctness of the ‘historical’ giant clam species defined solely on conchological characters, particularly T. maxima. This paper supports the retention of all giant clams in the family Tridacnidae, as distinct from the Cardiidae, because of their numerous morphological apomorphies, specialised ecological niche, and independent acquisition of symbiotic zooxanthellae.     

Morphology and Phylogeny of Two New Pleurostomatid Ciliates,Epiphyllum shenzhenense n. sp. and Loxophyllum spirellum n. sp. (Protozoa,Ciliophora) from A Mangrove Wetland,South China

ABSTRACT. The morphology, infraciliature, and small subunit (SSU) rRNA gene sequences of two new pleurostomatid ciliates, Epiphyllum shenzhenense n. sp. and Loxophyllum spirellum n. sp., isolated from a mangrove wetland near Shenzhen, South China, were investigated. Epiphyllum shenzhenense n. sp. is morphologically characterized by leaf‐shaped cell about 150 × 35 μm in vivo, usually with four contractile vacuoles, 20–29 right kineties and 10–26 left kineties, ca. four macronuclear nodules, and two types of extrusomes (i.e. short spindle‐shaped and long bar‐shaped). As a new species, L. spirellum n. sp. is distinguished from its congeners by its posterior dorsal margin twisted onto the left side, the distribution of extrusomes (evenly arranged along the oral slit, the posterior end, and clustered to 7–13 warts on dorsal margin), the subterminally positioned contractile vacuole, the number of kineties (8–10 on right side, 4–5 on left side), and its genetic distance from congeners. Phylogenetic trees based on the SSU rRNA gene sequence for both organisms were constructed, which indicate that Epiphyllum is a distinct genus and occupies a basal position in the Pleurostomatida clade; L. spirellum n. sp. falls well into the Loxophyllum clade, which has a close relationship with Litonotus and Spiroloxophyllum.     

Two New Brackish Ciliates,Amphileptus spiculatus sp. n. and A. bellus sp. n. from Mangrove Wetlands in Southern China,with Notes on the Molecular Phylogeny of the Family Amphileptidae (Protozoa,Ciliophora, Pleurostomatida)

Two new brackish pleurostomatid ciliates, Amphileptus spiculatus sp. n. and A. bellus sp. n. were collected from mangrove wetlands of southern China and their morphology and molecular phylogeny were studied. Amphileptus spiculatus sp. n. can be distinguished from congeners by the presence of 11–14 right and 6–8 left kineties, two macronuclear nodules and a conspicuous beak‐like anterior body end. Amphileptus bellus sp. n. is characterized by the presence of 2–4 macronuclear nodules, 31–35 right and 6 or 7 left kineties and two types of extrusomes. Phylogenetic analyses based on SSU rDNA sequences data indicate that the family Amphileptidae is paraphyletic.     

The Oocysts of Eimeria vermiformis sp. n. and E. papillata sp. n. (Protozoa: Eimeriidae) from the Mouse Mus musclus

SYNOPSIS. Eimeria vermiformis sp. n. and E. papillata sp. n. are described from the mouse Mus musculus. The sporulated oocysts of E. vermiformis are 18–26 by 15–21 μ (mean 23.1 by 18.4 μ); its sporocysts are 11–14 by 6–10 μ (mean 12.8 by 7.9 p). The sporulated oocysts of E. papillata are 18–26 by 16–24 μ (mean 22.4 by 19.2 μ); its sporocysts are 10–13 by 6–9 μ (mean 11.2 by 8.0 μ). A substiedal body is present in E. papillata sporocysts. Patent infections were produced in white laboratory mice with both species. Fourteen species of Eimeria have now been described from the genus Mus.     

Morphology and Phylogeny of Two Novel Ciliates,Arcanisutura chongmingensis n. gen., n. sp. and Naxella paralucida n. sp. from Shanghai,China

The morphologies of two novel ciliates, Arcanisutura chongmingensis n. gen., n. sp. and Naxella paralucida n. sp., collected from Shanghai, China, have been investigated using live observation and silver staining methods. Arcanisutura n. gen. can be easily distinguished from related genera by its inconspicuous, oblique anterior suture. Arcanisutura chongmingensis n. sp. is mainly recognized by its elongated body with a tail‐like posterior end, 25–33 somatic kineties, and 4–11 excretory pores. Naxella paralucida n. sp. can be distinguished from its congeners based on its two short nassulid organelles, fusiform trichocysts, 37–49 somatic kineties, and 16 nematodesmal rods. The small‐subunit (SSU) rRNA gene sequences of these two species are presented, revealing the phylogenetic positions of Arcanisutura and Naxella. Phylogenetic analyses show that Arcanisutura forms a sister clade to other synhymeniid genera, namely, Chilodontopsis, Orthodonella, and Zosterodasys; Naxella is most closely related to Nassula spp. and is located within the monophyletic clade of the family Nassulidae.     

Ortholinea alata n. sp. (Myxosporea: Ortholineidae) in the Northern Butterfly Fish Chaetodon rainfordi

Ortholinea alata n. sp. is described from the northern butterfly fish, Chaetodon rainfordi collected at Heron Island, Great Barrier Reef, Australia. Spherical, disporous trophozoites (10–15 μ) and spores were observed in the lumina of kidney tubules and collecting ducts. Spores are broadly triangular with two short, broad processes that extend dorsoventrad from the posterior end of each of the two spore valves. Valves are bisected by a suture in the plane of the polar capsules. Spores are 12.6 μ (length) × 9.6 μ (width) × 9.9 μ (length), and at the anterior end contain two spherical, divergent polar capsules measuring 4.6 ( 4.1 –5.1) μ. Sporogenesis is similar to that of renal Sphaerospora spp.: the intraluminal trophozoites of O. alata n. sp. correspond to pseudoplasmodia described for Sphaerospora spp. and no large, multinucleate plasmodia are formed. No significant histopathological changes were observed in the kidneys of infected fish.     

A peculiar new species in the genus Landouria Godwin-Austen, 1918 from China (Gastropoda: Heterobranchia: Stylommatophora: Camaenidae)

Landouria omphalostoma n. sp. is described from northern Yunnan, China. The new species is placed in the genus Landouria Godwin-Austen, 1918 based on the presence of tuberculated flagellum and swollen basal part in the bursa copulatrix, and on the absence of dart sacs and mucous glands. L. omphalostoma n. sp. is characterized by a horizontal aperture of the shell which is unique in the genus. This feature resembles those of only two other camaenid/bradybaenid taxa, species of the Chinese genus Pseudaspasita Möllendorff, 1902 and species of the Japanese genus Coelorus Pilsbry, 1900. This is the first verified record of the genus in China and the easternmost record of Landouria. This paper provides the taxonomic ground work for further studies of the repeated evolution of a horizontal aperture.     

New species of Eimeria (Apicomplexa: Eimeriidae) from the domesticated goat Capra hircus in New Zealand

Three new species of the genus Eimeria Schneider, 1875 are described from the faeces of domesticated goats in New Zealand. Oöcysts of E. capralis n. sp. are ellipsoidal, 29.2 × 19.7 (25–34 × 17–24) μm, with a distinct micropylar cap. The sporocysts are broadly ovoid, the Stieda body is present and the sporocyst residuum consists of many scattered granules. Sporozoites lie lengthwise head to tail in the sporocyst. Oöcysts of E. masseyensis n. sp. are broadly ellipsoid to ovoid, 22.3 × 17.4 (18–25 × 15–19) μm, with a distinct micropylar cap. The polar granules are shattered into fine granules, the sporocysts are elongate ovoid and the Stieda body is present. Oöcysts of E. charlestoni n. sp. are ellipsoidal, 22.9 × 17.4 (20–25 × 16–19) μm, with no micropylar cap. Its oöcysts are distinctive, with elongate sporocysts containing very prominent refractile bodies.     

A new species, <Emphasis Type="Italic">Orphnus drumonti</Emphasis> sp. n. (Coleoptera,Scarabaeidae), from the Democratic Republic of Congo

Three new scarab-beetle species are described. Aphodius moronensis sp. n. (northern Mongolia) and A. kozlovi sp. n (eastern Tibet) with modified spurs on fore tibiae in males are placed in the falcispinis group of the subgenus Agolius but are similar to the grafi group of the subgenus Chilothorax in the shape of parameres and elytral pattern. The new species differ from A. falcispinis in the shape of the spur; A. moronensis sp. n. also differs in the shape of the body and parameres. Orphnus transvaalensis sp. n. is the second apterous Orphnus species found in Southern Africa. It differs from the closely related O. harrisoni in the shape of parameres, position of the hornlike clypeal process, and in a smaller body size.     

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.     

Seven new coccidian species from marine fishes in Australia

One hundred and thirty fish of 15 species from the coast of northern New South Wales, Australia, were examined for coccidia. Seven new species, Eimeria cheilodactyli n. sp. and E. dykovae n. sp. from Cheilodactylus fuscus; E. pleurostici n. sp. from Sphaeroides pleurosticus; E. sillaginis n. sp., E. ciliatae n. sp. and Goussia arrawarra n. sp. from Sillago ciliata; G. microcanthi n. sp. from Microcanthus strigatus as parasites of the intestine; and a Goussia sp. from the liver of Rhabdosargus sarba are described.
