On the occurrence of blood flukes (Sanguinicolidae: Trematoda) in British freshwater fish

Summary

A new genus, Cahara, is described, based upon Dalpada brevivitta Walker, as its type species C. brevivitta (Walker) comb. nov., C. confusa (Distant) comb. nov. and C. jugatoria (Lethierry) comb. nov. are redescribed and illustrated. C. murreeana sp. nov., C. montana sp. nov., C. kightleyi sp. nov., C. chaubattia sp. nov., C. bhowaliana sp. nov. and C. metallica sp. nov. are described as new. The genus Cahara occurs in the subhimalayan region of India, Pakistan and Nepal. Its members feed on deciduous trees, apple, walnut, fir, deodar, Bauhinia, etc. Superficially, the species resemble one another, as well as members of Dalpada s. lat. in their coloration and some have been confused with species like Dalpada versicolor in the past, but certain characters, like the shape of the head, the simple second antennal segment and more particularly the male and female genitalia, distinguish the genus Cahara from all others. A key to the species of Cahara is provided.     

Two new genera of Epilachnini Mulsant from New Guinea and Aru Islands (Coleoptera: Coccinellidae)

The species formerly classified in the genus Afidentula Kapur from New Guinea and Aru Islands are revised. As a result of detailed analysis of mouth parts and genital structures of the species, two new genera are proposed: monotypic Lalokia gen. nov. from Aru Islands and New Guinea, with Lalokia aruensis (Crotch) (comb. nov.), and Papuaepilachna gen. nov. from New Guinea including Papuaepilachna bivacana (Bielawski) (comb. nov.), P. kapuri (Bielawski) (comb. nov.), P. nasti (Bielawski) (comb. nov.), P. tenmana (Bielawski) (comb. nov.), P. watalai (Jadwiszczak) (comb. nov.) and P. wiebesi (Bielawski) (comb. nov.). All species are illustrated and an identification key to the species of Papuaepilachna is provided. A key to the genera of Epilachnini from New Guinea and Aru Islands is also provided. http://www.zoobank.org/urn:lsid:zoobank.org:pub:F721B07F-CBF0-4516-853D-1FD434FE06F1     

The Philippine Coroebini (Coleoptera: Buprestidae: Agrilinae)

The known Philippine genera of Coroebini are briefly discussed and separated in an illustrated key. Vanroonia marmorea (Deyrolle), comb. nov., is transferred from Amorphosoma Laporte. Sibuyanella Obenberger is synonymized under Obenbergerula Strand, resulting in Obenbergerula bakeri (Fisher), comb. nov. Anocisseis samarensis, gen, et spec. nov., is described from Samar Island, Philippines. A Bornean species, Coroebus rajah Fisher, is transferred to Anocisseis.     

A revision of the subtribe Hippomelanina,part II: Gyascutus (Gyascutus) LeConte (Coleoptera: Buprestidae)

The subgenus Gyascutus (Gyascutus) is revised and 12 species are recognized: G. planicosta (LeConte) with three subspecies— G. p. planicosta (LeConte), stat. nov.; G. p. obliteratus (LeConte), stat. nov., with G. pistorius Casey as a syn. nov.; and G. p. cribriceps Casey, stat. nov.; with syn. nov. as follows: G. acutangulus Casey, G. amplus Casey, G. amplus aerata Casey, G. egregius Casey, and Hippomelas (G.) lariversi Barr; G. insularis (Helfer), comb. nov.; G. castaneus (Helfer), comb. nov.; G. fulgidus (Barr), comb. nov.; G. pacificus (Chamberlin), comb. nov.; G. paragranulatus Nelson, sp. nov.; G. granulatus (Van Dyke), comb. nov.; G. westcotti Nelson, sp. nov.; G. carolinensis Horn with syn. nov. as follows: G. juniperinus Wickham, G. obesus Casey, G. obesus aeneoviridis Casey, G. compactus Casey, G. compactus solidus Casey, G. cylindrinus Casey, G. debilis Casey, and G. tenuis Casey; G. dianae (Helfer), comb. nov.; G. allenrolfeae (Verity), comb. nov.; and G. jeanae (Nelson), comb. nov. All species and subspecies are described and information on type localities, variation, distribution, biology, and comparisons is presented. Keys to the species and subspecies are provided. Photographs of each species and drawings of body parts, including male genitalia, are included.     

Some flagellates (Protista) from tropical marine sediments

An account is given of 114 new or otherwise interesting species of benthic marine flagellates from Fiji, Northern Australia (Queensland), Hawaii, Panama and Brazil. Most species are heterotrophs drawn from the euglendis, dinoflagellates, kinetoplastids, bicosoecids, heteroloboseids, and a variety of taxa of uncertain affinities. The work emphasizes the rich variety of protist taxa in marine benthic sites. New names are Amphidinium corrugatum, Anisonema glaciale, Bodo cephalophorus, B. platyrhynchus, B. saliens, Bordnamonas tropicana, Cafeteria ligulifera, C. marsupialis, C. minuta (Ruinen, 1938) nov. comb., Cryptaulax elegans, Dinematomonas inaequalis = Dinema inaequale, Dinematomonas maculata (= Dinema maculatum), Dinematononas valida (= Dinema validum), Diplonema ambulator, Diplonema metabolicum, Discocelis punctata, Dolium sedentarium, Goniomonas amphinema, Goniomonas pacifica, Gyrodinium oblongum, Heteronema exaratum, H. splendens, H. vittatum, Mastigamoeba psammobis, M. skujae nom. nov., Massisteria marina, Metopion fluens, Metromonas grandis, M. simplex (Griessmann, 1913) nov. comb., Notosolenus alatellus, N. navicula, N. ostium, N. scutulum, N. urceolatus, N. tamanduensis, N. triangularis, Percolomonas cuspidata, P. descissa (Perty, 1852) nov. comb., P. elephas (Klug, 1936) nov. comb., P. membranifera, P. pyriformis (Klebs, 1892) nov. comb., P. salina (Entz, 1904) nov. comb., P. spinosa (Klug, 1936) nov. comb., P. sulcata (Stein, 1878) nov. comb., Petalomonas boadicea, P. marginalis, P. minor, P. poosilla, P. raiula, Phyllomitus granulatus, P. vesiculosus, Platychilomonas psammobia, Ploeotia adhaerens, P. corrugata, P. decipiens, P. heracleum, P. discoides, P. longifilum, P. oblonga, P. pseudanisonema, P. punctata, P. robusta, P. scrobiculata, P. tenuis, Protaspis obliqua, P. verrucosa, P. gemmifera, P. tegere, Pseudoperanema (= Peranema) dolochonema, Thecamonas filosa, T. mutabilis (Griessmann, 1913) nov. comb., T.trahens, Urceolus cornutus, U. cristatus.     

Chinese psyllids in the genus Cacopsylla (Hemiptera: Sternorrhyncha: Psylloidea) associated with Spiraea (Rosaceae)

The Chinese Cacopsylla species associated with Spiraea are revised. Three new species (Cacopsylla falcata sp. nov., C. nocturna sp. nov. and C. qilianensis sp. nov.) are described, and two [C. hyalinonemae Li and Yang, 1989 and C. spiraeicola (Li, 2011) comb. nov.] are redescribed. A new combination is also proposed for Cacopsylla tetrotaenialis (Li and Yang, 1989) comb. nov. Among the five species, C. falcata and C. qilianensis are affirmed to develop on Spiraea, as fifth instar immatures were found. The host plants of the other species remain uncertain. Based on morphological grounds, it is suggested that C. falcata and C. nocturna are closely related, but that the five species associated with Spiraea do not constitute a monophyletic group.     

Studies on gorgoderid digeneans from Australian and Assian Freshwater fishes

Pseudophyllodistomum gen. nov. is proposed for a section of Phyllodistomum Braun, 1899. The new genus is distinguished by the simple form of the uterus, the eggs which reach over 60 μm long in length, the saccular excretory bladder, the 2[3 + 3 + 3) + (3 + 3 + 3)] = 36 flame-cell formula, the metacercaria which may have fully developed genitalia and is parasitic in decapod crustaceans, the use of corbiculid bivalves as first intermediate hosts, and the cercaria which has a long tail not enclosing the cercarial body. Two species, P. johnstoni sp. nov. and P. murrayense sp. nov., are described from Australian freshwater fish and five new combinations of previously described Phyllodistomum species from Asian freshwater fish are proposed — P. macrobrachicola (Yamaguti, 1934) comb. nov., P. lesteri (Wu, 1938) comb. nov., P. srivastavai (Rai, 1964) comb. nov., P. lucknowense (Pandey, 1970) comb. nov. and P. mingense (Tang, 1985) comb. nov. The first intermediate host of P. johnstoni is a Corbiculina species. The long-tailed cercariae infect the gonads of palaemonid prawns, Macrobrachium spp., in which they grow to unencysted metacercariae which may have fully developed genitalia. The metacercaria of P. murrayense also infects a Macrobrachium species. The evolution of the Gorgoderinae is discussed and it is suggested that, prior to the erection of Pseudophyllodistomum, Phyllodistomum may have encompassed as many as five different phylogenetic lines, each with similar adult morphology but distinguishable by life-cycle characters. It is postulated that more study will lead to further division of Phyllodistomum.     

A new deep-water calanoid copepod and the phylogeny of the genus Nullosetigera nom. nov. in the Nullosetigeridae nom. nov. (pro Phyllopus: Phyllopodidae) from Japanese waters

Nullosetigeridae nom. nov. is proposed for Phyllopodidae Brodsky, 1950, nom. nud., and Nullosetigera nom. nov. is introduced for Phyllopus Brady, 1883, non Rafinesque, 1815. A new species, Nullosetigera auctiseta, is described from Japanese waters. Nullosetigera mutica comb. nov. (Sars, 1907) and N. mutata comb. nov. (Tanaka, 1964) are redescribed. Phylogenetic analysis implies that two groups, N. auctiseta–N. mutica group and N. mutata–N. impar–N. bidentata–N. helgae group, exist within the genus Nullosetigera and that the new species first diverges with N. mutica. The relatively advanced species, N. impar, N. bidentata, and N. helgae are the most widespread, and are vertically distributed from the epipelagic to the bathypelagic layers.     

African Derbidae (Homoptera,Fulgoroidea): taxonomic notes with descriptions of new species collected mainly from coconut

An annotated list of the African Derbidae described since Synave's 1973 monograph is given, with some corrections and additions to that work together with a revision of the genus Robigus from Africa. The following new species are described: Diostrombus schuilingi sp. nov., D. mkurangai sp. nov., Zorabana vipaku sp. nov., Patara minazi sp. nov., P. chambeziensis sp. nov., Paraphenice mawai, sp. nov., Phenice pongwei sp. nov., Robigus magawai sp. nov., Robigus synavei sp. nov. (= R. tortrinotatus sensu Synave, 1973), Kamendaka ukutu sp. nov. All of these new species with the exception of R. synavei were collected from coconut. The following new synonomies are made: Proutista fritillaris (Boheman) = P. tesselata (Westwood) syn. nov., Diostrombus abdominalis (Distant) = D. moerensis Synave syn. nov., Paraphenice dissimilis Synave = Pamendanga fuscinervis Van Stalle syn. nov., Zoraida fuligipennis Muir = Z. nigeriensis Synave syn. nov., Platocera africana Muir, omitted in error from Synave (1973), is described and figured. Proutista moesta (Westwood) is recorded from Africa for the first time.     

The Andean tarantulas Euathlus Ausserer, 1875, Paraphysa Simon, 1892 and Phrixotrichus Simon, 1889 (Araneae: Theraphosidae): phylogenetic analysis,genera redefinition and new species descriptions

Based on a phylogenetic analysis we revised the Chilean tarantula genera Euathlus and Paraphysa. As results of our analyses, within a wider context of South American lineages, Paraphysa is synonymous of Euathlus, and Phrixotrichus is resurrected. Euathlus and Phrixotrichus are sister genera, supported by their shared palpal organ morphology, especially at the ventral position of the distal prolateral inferior keel, also by spermathecal receptacles with a lateral chamber, and tarsal claws without teeth. Both genera are redefined based on cladistic results, and some of their constituent species are transferred. We describe four new species, and for the first time present the spermathecae of Euathlus parvulus comb. nov. All species described for both genera are diagnosed and keyed. Euathlus now includes: Euathlus antai Perafán and Pérez-Miles sp. nov., Euathlus atacama Perafán and Pérez-Miles sp. nov., Euathlus condorito Perafán and Pérez-Miles sp. nov., Euathlus manicata (Simon 1892) comb. nov., Euathlus parvulus (Pocock, 1903) comb. nov. and Euathlus truculentus L. Koch, 1875. Phrixotrichus now comprises: Phrixotrichus jara Perafán and Pérez-Miles sp. nov., Phrixotrichus scrofa (Molina, 1788) comb. nov. and Phrixotrichus vulpinus (Karsch, 1880) comb. nov. Furthermore, Paraphysa riparia Schmidt and Bolle, 2008 is synonymized with Eupalaestrus weijenberghi (Thorell, 1894), Paraphysa pulcherrimaklaasi Schmidt, 1991 is transferred to Maraca Pérez-Miles, 2006 and Paraphysa peruviana Schmidt, 2007 is considered a nomen dubium.

Partial revision of the Indo-Australian braconine wasp genus Gammabracon Quicke (Hymenoptera: Braconidae) with descriptions of new species from Indonesia (Mollucas), Malaysia,Philippines and Thailand

Ten distinctive new species of the taxonomically difficult braconine wasp genus Gammabracon Quicke, 1984 are described: G. apicoluteus sp. nov. from Malaysia (Negri); G. curticornis sp. nov. from Malaysia (Negri); G. philippinensis sp. nov. from the Philippines; G. siamensis sp. nov. from Thailand; G. striatus sp. nov. from West Malaysia; G. strandorum sp. nov. from Indonesia (Java), G. subvena sp. nov. from Malaysia (Negri and Sabah); G. townesorum sp. nov. from the Philippines; G. variipennis sp. nov. from Thailand; and G. wegeneri sp. nov. from Indonesia. Myosoma forticarinata Cameron, 1902 is transferred to Gammabracon, hence Gammabracon forticarinata comb. nov. A lectotype is designated for Gammabracon erythroura (Cameron). The status of Cratobracon strandiellus (Cameron) is discussed and a new combination proposed, Shelfordia strandiellus Cameron, 1910 comb. nov. (=Bracon strandiellus Cameron). Paucity of discrete morphological variation makes separation of most of the species with orange-red mesosoma, black metasoma and conspicuous back setae currently unrealistic and it may be that there is a single widespread and morphologically variable species.

A new leaf-resembling genus of bush-cricket from West Africa (Orthoptera: Tettigoniidae)

Trimusculotrema warnaki gen. et sp. nov. is described from the skin of Himantura uarank Forsskål. Trimusculotrema is distinguished from other genera in the Benedeniinae by the following combination of anatomical features: accessory sclerites and anterior hamuli small; haptor with two or three intrinsic, concentric muscle bands; haptor papillate ventrally; cirrus sac with internal seminal vesicle and spermatophore matrix reservoir; separate male and female pores opening ventrally and dorsally respectively; vagina short. On the basis of these features Benedenia micracantha Euzet and Maillard, 1967 from the skin and B. leucanthemum Euzet and Maillard, 1967 from the gills of Dasyatis marmorata Steindachner off Senegal are transferred to the new genus as Trimusculotrema micracantha comb. nov. and T. leucanthemum comb. nov. The presence of haptoral papillae, noted previously in some species of Entobdella, perhaps indicates that the new genus is more closely related to entobdellids than to benedeniids. Several living specimens of T. uarnaki had 7 (2–17) eggs in early cleavage projecting from the body, their appendages gripped in a muscular sphincter at the uterine opening. These egg bundles appear to be shed from the parasite soon after laying.     

Zenkevitchiidae fam. nov. (Crustacea: Gammaroidea), with description of new subterranean amphipods from extremely deep cave habitats

Previous phylogenetic analysis based on combined mitochondrial and nuclear gene sequences detected paraphyly of the Typhlogammaridae. To test this hypothesis a portion of large subunit (LSU-rDNA) gene sequences were obtained for typhlogammarid species from Caucasus. The Bayesian approach to LSU-rDNA sequences provided evidence for an independent origin of the Dinaric and Caucasus ‘typhlogammarid’ clades. A new family, Zenkevitchiidae fam. nov., is proposed to reconcile the observed phylogeny with the concept of monophyly. Using light microscopy, two mouthpart morphotypes of the Zenkevitchiidae fam. nov. species with quite different setae are identified. Taking into account these two morphotypes, a new classification is proposed – Adaugammarus revazi comb. nov., and Adaugammarus sandroruffoi comb. nov. Additionally, two new stygobiont zenkevitchiid amphipod species – Adaugammarus kasiani sp. nov. and Kruberia relicta sp. nov. – are described from Krubera Cave in Abkhazia. A distribution map and an identification key for the Zenkevitchiidae fam. nov. species of Transcaucasia are provided.

A revision of the Labiidae (Dermaptera) of the Neo-tropical and Nearctic Regions

A new genus, Helenolius (Cixiidae, Pentastirini), is described to accommodate the species H. dividens (Walker) comb. nov. and H. insulicola sp. nov. Both species are described and illustrated; they are endemic on the island St Helena.     

On Anomalotrema Zhukov, 1957, Pellamyzon Montgomery, 1957, and Opecoelina Manter, 1934 (Digenea: Opecoelidae), with a description of Anomalotrema koiae sp. nov. from North Atlantic waters

In order to clarify the systematic position of some opecoeline digeneans parasitic in scorpaenid and gadid fishes from the northern North Atlantic, a study of the genera Anomalotrema Zhukov, 1957, Pellamyzon Montgomery, 1957, and Opecoelina Manter, 1934, was carried out. Anomalotrema is retained in the subfamily Opecoelinae and A. koiae sp. nov. is described for the worms from scorpaenids and gadids which prompted the investigation. This species is distinguished from the Pacific species, A. putjatini Zhukov, 1957, on morphological and biological grounds. Pellamyzon is transferred to the Plagioporinae. A new subfamily, the Opecoelininae subfam. nov., is erected for Opecoelina, which is considered to contain only two or three valid species, O. scorpaenae Manter, 1934, O. helicoleni Manter, 1934 (possibly a synonym of O. scorpaenae) and O. pacifica Manter, 1940. Both O. theragrae Lloyd, 1938, and O. radifistuli (Acena, 1941) are transferred to the genus Podocotyle Dujardin, 1845, as P. theragrae comb. nov. and P. radifistuli comb. nov. O. pharynmagna Annereaux, 1943, is judged to be a synonym of P. radifistuli, and both O. vixiintestina Oshmarin, 1965, and O. vixigastera Oshmarin, 1965, are considered unrecognizable. The possible evolutionary relationships of the subfamilies within the Opecoelidae are commented on.     

Review of the genus Bolbonaso Emeljanov with checklist and key to Indian Caliscelidae (Hemiptera: Fulgoroidea)

A list of species of the family Caliscelidae Amyot et Serville known from India with data on distribution and sources for identification and a key to genera are given. The genus Bolbonaso Emeljanov, 2007 is revised. A new species, Bolbonaso chandri sp. nov., is described from Eastern India (Assam and Meghalaya States). Bolbonaso tapirifacies (Parshad, 1981) is redescribed and recorded for the first time from Southern India (Karnataka State). The lectotype is designated for Chirodisca eximia (Stål, 1859) which is recorded for the first time from Pakistan. New faunistic data in Nepal are listed for Delhina eurybrachydoides Distant, 1912.     

Rediscovery of Disepyris semiruber (Kieffer) (Hymenoptera: Bethylidae) in Southern Africa,with first description of the male

Holepyris semiruber Kieffer is redescribed and illustrated based on freshly collected specimens. Holepyris semiruber var. striatipleura Kieffer is considered a colour variant of this species and therefore a junior synonym of H. semiruber syn. nov. This species is transferred to Disepyris, D. semiruber (Kieffer) comb. nov., based on the possession of a short 2r-rs&Rs vein in the fore wing and presence of long flat spine-shaped setae on the outer (posterior) surface of the protarsi. The male is described for the first time from new specimens collected in South Africa. This species is recorded for the first time from Namibia and Zimbabwe. All photographs are available on www.waspweb.org.     

A new genus and two new species of Parastenocarididae (Copepoda: Harpacticoida) from southeastern India

Indocaris gen. nov. with two new species, Indocaris imbricata sp. nov. and Indocaris inopinata sp. nov., and also for the already known Indocaris tirupatiensis (Ranga Reddy 2011a) comb. nov. – all from the groundwaters in peninsular India. The highly diagnostic synapomorphy of the new genus is a composite character associated with the male leg 4 basis: five or six prominent, imbricate, enlarged, petal-like spinules, arranged as a semi-whorl at the insertion of the endopod and increasing in size from internal to external. Another distinctive feature of the same appendage is that its one-segmented endopod is dilated or bulbous in the proximal half, produced distally into an incurved spiniform or horn-like structure about as long as the corresponding first exopodal segment, and ornamented with three or four fine spinules on the subproximal outer margin. The three species also share a unique constellation of other salient morphologic features, which along with the phylogenetic position of Indocaris gen. nov. within the family Parastenocarididae are discussed. Indocaris gen. nov. has closest phylogenetic affinity with the Neotropical Remaneicari Jakobi, 1972. A short note on the ecology and biogeography of the parastenocaridid species of the Indian subcontinent is provided besides a key for their identification.
