Phylogenetic systematics of the Empis (Coptophlebia) hyalea-group (Insecta: Diptera: Empididae)

Six clades are inferred from a phylogenetic analysis including 42 species belonging to the Empis (Coptophlebia) hyalea‐group. These clades are named as follows: E. (C.) acris, E. (C.) aspina, E. (C.) atratata, E. (C.) hyalea, E. (C.) jacobsoni and E. (C.) nahaeoensis. The presence of two dorsal more or less developed epandrial projections is considered autapomorphic for the E. (C.) hyalea‐group in addition to two characters previously found to support the monophyly of this group (presence of an unsclerotized zone in the middle of labella and epandrium unpaired). Amongst the cladistically analysed species, 24 are newly described [ E. ( C. ) acris , E. ( C. ) aspina , E. ( C. ) cameronensis , E. ( C. ) duplex , E. ( C. ) incurva , E. ( C. ) inferiseta , E. ( C. ) kuaensis , E. ( C. ) lachaisei , E. ( C. ) lamellalta , E. ( C. ) lata , E. ( C. ) loici , E. ( C. ) longiseta , E. ( C. ) mengyangensis , E. ( C. ) menglunensis , E. ( C. ) missai , E. ( C. ) nimbaensis , E. ( C. ) padangensis , E. ( C. ) parvula , E. ( C. ) projecta , E. ( C. ) pseudonahaeoensis , E. ( C. ) submetallica , E. ( C. ) urumae , E. ( C. ) vitisalutatoris and E. ( C. ) woitapensis ], five are reviewed [E. (C.) hyalea Melander, E. (C.) jacobsoni De Meijere, E. (C.) ostentator Melander, E. (C.) sinensis Melander and E. (C.) thiasotes Melander] and 13 were recently described in two previous papers. Two additional species, E. (C.) abbrevinervis De Meijere and E. (C.) multipennata Melander, are also reviewed but not included in the cladistic analysis since they are only known from the female. A lectotype is designated for E. (C.) jacobsoni. A key is provided to the six clades of the E. (C.) hyalea‐group as well as to species of each clade. A catalogue of the E. (C.) hyalea‐group, including 72 species, is given. The taxonomic status of 25 additional species mainly described by Bezzi and Brunetti, from the Oriental and Australasian regions, is discussed. The E. (C.) hyalea‐group is firstly recorded from the Palaearctic Region and Australia. Finally, the distribution and the habitats of the species compared with their phylogeny suggest a possible relationship between the diversification of the group and forest fragmentations during the Quaternary. © 2005 The Linnean Society of London, Zoological Journal of the Linnean Society, 2005, 145 , 339–391.     

Australian Iphimediidae (Crustacea: Amphipoda)

Australian species of the iphimediid amphipod genus Iphimedia are revised. Based on new material from inshore and continental shelf habitats six new species are described: Iphimedia beesleyae; I. filmersankeyi; I. kateae; I. lisae; I. neuweileri and I. oetkeri. Four established species are redescribed: I. ambigua Haswell, 1879; I. discreta Stebbing, 1910; I. edgari (Moore, 1981) and I. warraina (Thomas and Barnard, 1991). A key to Australian species of Iphimedia is provided. Full article published online at http://www.senckenberg.de/odes/06-09.htm     

Carnoya kermarreci n.sp. (Rhigonematidae: Nematoda) from Anadenobolus politus (Porat) (Rhinocricidae: Diplopoda) from Guadeloupe

Summary Carnoya kermarreci n.sp. (Rhigonematidae; Nematoda) is described from Anadenobolus politus (Porat) (Rhinocricidae; Diplopoda) from Guadeloupe. The new species most closely resembles C. martiniquensis Adamson, 1984 from A. politus in Martinique and C. venezuelensis Adamson, 1984 from Rhinocricus flavocinctus from Venezuela in that the lips in the male are broad and the arrangement of caudal papillae is almost identical in the three species. Males of C. kermarreci are easily distinguished by the absence of spines, by the form of the cuticular projections at the base of the buccal cavity and by the fact that the most anterior pair of caudal papillae are located very close together. Females are distinguished by the presence of three pairs of somatic papillae near the level of the vulva. The nematode fauna of A. politus includes species from two distinct orders and presumably reflects the fact that diplopods are among the most ancient hosts of nematodes.     

Siteroptes (Siteroptoides) species with Pediculaster-like phoretomorphs (Acari: Tarsonemida: Pygmephoridae) from New Zealand and Polynesia

Abstract

Six species of Siteroptes subgenus Siteroptoides—kneeboni (Wicht), mesembrinae (Canestrini), microsaniae n.sp., morelliae (Rack), muscarius n.sp., and portatus n.sp.—have been found in New Zealand. S. (S.) mesembrinae occurs on Niue Island also, and a further new species, pacificus, is recorded from Tonga. The phoretomorph females of all 7 species, the normal females of 4, the males of 3, and larvae of 2 are described and compared. The similarities and differences between normal and phoretomorph females are particularly noted. Besides kneeboni, 2 species described by Wicht but not occuring in New Zealand—athiasae and flechtmanni— are redescribed from type material and transferred to Siteroptes (Siteroptoides). Keys are given for normal females and Pediculaster-like phoretomorph females of Siteroptoides. Siteroptes mesembrinae subsimilis and S. ignotus altaicus are raised to species status. Diagnostically important measurements are given to help define the variation within and between species and morphs.     

Autalia rivularis (Gravenhorst) and Brachida clara (Weise) new to Korea (Coleoptera: Staphylinidae: Aleocharinae)

Two aleocharine species, Autalia rivularis (Gravenhorst) and Brachida clara (Weise), are identified for the first time in Korea. Diagnoses, habitus illustrations, and line drawings of diagnostic characters are provided.     

Species in the genus Rhytidelasma Gaud (Acarina: Pterolichidae) from the Green Conure,Aratinga holochlora (Sclater) (Aves: Psittacidae)

Three species in the genus Rhytidelasma Gaud (Pterolichoidea: Pterolichidae) are known from the Green Conure, Aratinga holochlora (Sclater): R. cornigera n. sp., R. urophila n. sp. and R. mesomexicana Atyeo et al. The new species are described, and the microhabitat(s) for each species discussed.     

Nanocladius (Plecopteracoluthus) asiaticus sp. n. (Diptera: Chironomidae) Phoretic on Dobsonfly and Fishfly Larvae (Megaloptera: Corydalidae)

The adult male, adult female, pupa, and larva of Nanocladius (Plecopteracoluthus) asiaticus sp. n. (Diptera: Chironomidae) are described and illustrated. Larvae live in coarse silken nets which usually are attached to the ventral side of the mesothorax of larval dobsonflies and fishflies (Megaloptera: Corydalidae) dwelling in stream riffles. The host species are Protohermes grandis and Parachauliodes continentalis in Japan, Protohermes costalis and Neochauliodes sinensis in Taiwan, and Neurhermes maculipennis in the Malay Peninsula. Larvae are not parasitic but may have a commensal relationship with their hosts; they feed on algae and detrital material caught on their silken nets, or on the body surface of their hosts. Pupation occurs in the fine silken net fixed to the lateral side of host thoracic regions, or occasionally to the undersides of hind legs.     

Three new mermithids (Nematoda) from Guatemalan blackflies (Diptera: Simuliidae)

Summary The following new species of Mermithidae (Nematoda) are described from Guatemalan blackflies: (a) Gastromermis cloacachilus from Gigantodax wrighti; (b) Isomernis vulvachila from Cnephia pacheco-lunai and (c) Mesomermis guatemalae from Simulium metallicum. All parasites were collected at Encuentros (Department of Totonicapan) in Guatemala. These are the first representatives of Gastromermis and Mesomermis from Central America and M. guatemalae represents the second mermithid species to be described from an American vector of Onchocerca volvulus, causal agent of river blindness. ac]19800728     

Predation of Thereva nobilitata (Fabricius) (Diptera: Therevidae) on Agriotes obscurus L. (Coleoptera: Elateridae)

Little is known about the natural enemies of wireworms (Coleoptera: Elateridae), but there are frequent anecdotal reports of (usually unnamed) stiletto fly larvae (Diptera: Therevidae) preying on various species. We observed larvae of Thereva nobilitata (Fabricius) feeding on larvae of the dusky wireworm, Agriotes obscurus L., during the summer of 2011, in Agassiz, British Columbia. This finding is of interest as: both the predator and the wireworm are introduced species to this area from Europe; T. nobilitata is uncommon in North America; and this predator has not been associated with any wireworm species previously. We observed that larvae of male and female T. nobilitata will feed on various sizes of A. obscurus larvae, most feeding being carried out by the smallest T. nobilitata larvae. These findings suggest future work should assess the potential for therevid larvae as top‐down regulators of Agriotes larvae under field conditions.     

Philopotaminae of Madagascar (Trichoptera: Philopotamidae)

The Malagasy fauna includes two genera of Philopotaminae: Wormaldia McLachlan 1865 and an endemic new genus, Ranarijaodes n. gen. The Malagasy and African (sensu stricto) lineages of Wormaldia are distinct. Apomorphic characters (the shape of the phallic apparatus for the African species and the splitting of the median lobe of the tenth tergite for the Malagasy species) confirm their separation. New captures are reported for two of the four previously known species of Wormaldia. Seven new species are described: Wormaldia ambahibeae n. sp., W. faharoa n. sp., W. fahatelo n. sp., W. randriamasimananai n. sp., W. fahefatra n. sp., W. legrandi n. sp. and W. fahadimy n. sp. Ranarijaodes n. gen. is close to Dolophilodes Ulmer 1909. It is described for the three new species Ranarijaodes fiana n. sp., R. angapi n. sp. and R. atsimo n. sp. The 14 Malagasy species of Philopotaminae are endemics of the island. Their geographical distributions and ecological preferences are described and discussed.     

Systematics of rove beetles (Coleoptera: Staphylinidae: Aleocharinae) associated with Hodotermopsis sjostedti (Isoptera: Termopsidae)

Members of the termitophilous subtribe Termitozyrina (Aleocharinae: Lomechusini) associated with Hodotermopsis sjostedti are taxonomically treated. The genera Hodotermophilus Naomi & Terayama and Termophidoholus Naomi & Hirono, and each type species (monotypic) are redescribed. Termophidoholus formosanus, originally described from Taiwan, and its host termite H. sjostedti are newly recorded from Laos. Yakuus iwatai Kanao & Maruyama gen. & sp. nov. and H. gloriosus were collected sympatrically in the same nests in Yaku‐shima, Japan. All of the above species, belonging to the three genera, share the presence of a batch of spurs at the tibial apex of fore and mid legs. Habitus photographs and illustrations of diagnostic features are provided for these species, and their phylogenetic relationships are discussed based on morphological similarities and the extant distribution of the host termite species.     

New Zealand Recent Hyriidae (Mollusca: Bivalvia: Unionida)

The New Zealand freshwater mussels are taxonomically revised and compared with key Australian and South American taxa using DNA sequence data. Three living species are recognised: Echyridella menziesii, Echyridella aucklandica and Echyridella onekaka. Cucumerunio websteri websteri and Cucumerunio websteri delli, are treated as junior synonyms of Unio aucklandica, which is transferred from Cucumerunio (and Hyridella) to Echyridella. Lectotypes are designated for Unio waikarensis and Unio hochstetteri, which are illustrated together with primary type specimens of other relevant taxa. The type locality of U. aucklandica is restricted to the catchment of the Kawakawa River.     

Strong indirect interactions of Tarsonemus mites (Acarina: Tarsonemidae) and Dendroctonus frontalis (Coleoptera: Scolytidae)

Phoretic mites of bark beetles are classic examples of commensal ectosymbionts. However, many such mites appear to have mutualisms with fungi that could themselves interact with beetles. We tested for indirect effects of phoretic mites on Dendroctonus frontalis, which attacks and kills pine trees in North America. Tarsonemus mites are known to carry ascospores of Ophiostoma minus, which tends to outcompete the mutualistic fungi carried by D. frontalis. Experimental additions and removals of mites from beetles demonstrated that Tarsonemus propagate O. minus in beetle oviposition galleries. Furthermore, the abundance of Tarsonemus and O. minus tended to covary in nature. These results verified a strong mutualism between Tarsonemus and O. minus. Results also indicated that O. minus is an antagonist of D. frontalis: beetle larvae seldom survived in the presence of O. minus (compared to 83% survival elsewhere). Apparently, this is an indirect result of O. minus outcompeting the two species of mycangial fungi that are critical to beetle nutrition. Thus, Tarsonemus mites close a loop of species interactions that includes a commensalism (mites and beetles), a mutualism (mites and O. minus), asymmetric competition (O. minus and mycangial fungi), and another mutualism (mycangial fungi and beetles). This interaction system produces negative feedback that could contribute to the endogenous population dynamics of D. frontalis. Reproductive rate of Tarsonemus was more temperature‐sensitive than beetle generation time (which constrains the time for mite reproduction within a tree). This differential temperature sensitivity produces a narrow range of temperatures (centred at 27°C) in which mite reproduction per D. frontalis generation can attain its maximum of 100 mites/beetle. Consequently, seasonal oscillations in temperature are predicted to produce oscillations in the D. frontalis community, and climatic differences between regions could influence the community to dampen or exacerbate the cyclical outbreak dynamics of D. frontalis.     

Beschreibung einer neuen Carabus (Lamprostus)-Art aus Persien (Coleoptera: Carabidae)

Abstract

A new species of Carabus (Lamprostus) from the province of Gilan, Iran, is described and illustrated: Carabus (Lamprostus) staveni sp. nov., Carabus (Pachystus) rechingerae Mandl, 1972, is considered a junior synonym of Carabus (Lamprostus) calleyi nigrinus Motschulsky, 1865. The specific status of Carabus (Sphodristocarabus) korgei Heinz, 1970, is restored (stat. rev.) and Carabus separatus delirensis Deuve, 2000, is considered to be a junior synonym of it. Carabus (Megodontus) stroganowi javahardensis Deuve, 2000, is considered to be a synonym of Carabus (Megodontus) heinrichi Mandl, 1966; both taxa are from the same type locality.     

Typhlocybinae of New Zealand (Homoptera: Cicadellidae)

Two tribes of the subfamily Typhlocybinae are represented in New Zealand, as follows. Erythroneurini: the cosmopolitan genus Zygina is represented by 4 endemic species—toetoe, ramsayi n.sp., dumbletoni, and agni n.sp.—plus zealandica, which occurs in Australia also. Typhlocybini: Typhlocyba froggatti, T. lethierryi, Ribautiana tenerrima, Eupteryx melissae, Kybos smaragdula, and K. betulicola are introduced Northern Hemisphere elements; Matatua montivaga n.gen.&sp. is endemic; M. maorica (formerly Dikraneura maorica), also endemic, is of uncertain identity in the absence of male specimens. Keys are given for the separation of all taxa, the genera and species are described, and all species except Matatua maorica are figured.     

The salivary gland chromosomes of Culex (Culex) vishnui (Culicidae: Diptera)

Culex vishnui is a member of the vishnui group comprising six closely resembling species. The salivary gland chromosomes are longer than those found in Anopheles, more fragile and spread with difficulty. The banding pattern is compared with that of Culex pipiens pipiens and Culex pipiens fatigans. Homologies are closest between vishnui and fatigans. The incidence of asynapsis between the homologues is very high.     

Life history stages and taxonomy of Austrosimulium (Austrosimulium) tillyardianum (Diptera: Simuliidae)

The male, female, pupa, 9th‐instar larva, and egg of Austrosimulium (Austrosimulium) tillyardianum Dumbleton, 1973, are redescribed, and larval instars one to eight are described and morphologically differentiated for the first time. The relationship of A. (A.) tillyardianum to other New Zealand species is briefly reviewed.     

Putative fasciclin-like arabinogalactan-proteins (FLA) in wheat (Triticum aestivum) and rice (Oryza sativa): identification and bioinformatic analyses

Putative plant adhesion molecules include arabinogalactan-proteins having fasciclin-like domains. In animal, fasciclin proteins participate in cell adhesion and communication. However, the molecular basis of interactions in plants is still unknown and none of these domains have been characterized in cereals. This work reports the characterization of 34 wheat (Triticum aestivum) and 24 rice (Oryza sativa) Fasciclin-Like Arabinogalactan-proteins (FLAs). Bioinformatics analyses show that cereal FLAs share structural characteristics with known Arabidopsis FLAs including arabinogalactan-protein and fasciclin conserved domains. At least 70% of the wheat and rice FLAs are predicted to be glycosylphosphatidylinositol-anchored to the plasma membranes. Expression analyses determined from the relative abundance of ESTs in the publicly available wheat EST databases and from RNA gel blots indicate that most of these genes are weakly expressed and found mainly in seeds and roots. Furthermore, most wheat genes were down regulated by abiotic stresses except for TaFLA9 and 12 where cold treatment induces their expression in roots. Plant fasciclin-like domains were predicted to have 3-D homology with FAS1 domain of the fasciclin I insect neural cell adhesion molecule with an estimated precision above 70%. The structural analysis shows that negatively charged amino acids are concentrated along the β1-α3-α4-β2 edges, while the positively charged amino acids are concentrated on the back side of the folds. This highly charged surface distribution could provide a way of mediating protein–protein interactions via electrostatic forces similar to many other adhesion molecules. The identification of wheat FLAs will facilitate studying their function in plant growth and development and their role in stress response.Nucleotide sequence data reported are available in the DBJ/EMBL/GenBank databases under the accession numbers: TaFLA1, DQ872374; TaFLA2, DQ872375; TaFLA3, DQ872376; TaFLA4, DQ872377; TaFLA5, DQ872378; TaFLA6, DQ872379; TaFLA7, DQ872380; TaFLA8, DQ872381; TaFLA9, DQ872382; TaFLA10, DQ872383; TaFLA11, DQ872384; TaFLA12, DQ872385; TaFLA13, DQ872386; TaFLA14, DQ872387; TaFLA15, DQ872388; TaFLA16, DQ872389; TaFLA17, DQ872390; TaFLA18, DQ872391; TaFLA19, DQ872392; TaFLA20, DQ872393; TaFLA21, DQ872394; TaFLA22, DQ872395; TaFLA23, DQ872396; TaFLA24, DQ872397; TaFLA25, DQ872398; TaFL26, DQ872399; TaFLA27, DQ872400; TaFLA28, DQ872401; TaFLA29, DQ872402; TaFLA30, DQ872403; TaFLA31, DQ872404; TaAGP1, DQ872405; TaFLA33, DQ872406; TaFLA34, DQ872407.

Scymnodon plunketi (Waite, 1910): a junior synonym of Scymnodon macracanthus (Regan, 1906) (Somniosidae: Elasmobranchii)

The taxonomic status and validity of Scymnodon macracanthus (Regan, 1906) and Scymnodon plunketi (Waite, 1910) are revised in light of new material from the Southern Pacific and Indian Oceans. Despite being historically accepted as distinct taxa, recent studies suggested the possibility that these species could represent a single taxon. Morphometrics, meristics and morphology of dermal denticles show that S. plunketi is indeed a junior synonym of S. macracanthus. Previous distinctive characters proved to be the result of intraspecific variation. S. macracanthus is therefore redescribed including an updated comparative diagnosis for the genus Scymnodon in the family Somniosidae.     

Prosorhynchine trematodes (Digenea: Bucephalidae) from epinephelines (Perciformes: Serranidae) on the Great Barrier Reef,Australia

Six new species of bucephalid trematodes from the prosorhynchine bucephalid genera Prosorhynchus Odhner, 1905 and Neidhartia Nagaty, 1937 are reported from the epinepheline genera Cephalopholis, Cromileptes, Epinephelus and Variola on the Great Barrier Reef, Australia. Two species of Prosorhynchus and one of Neidhartia are reported from Epinephelus spp., P. jexi n. sp. from E. quoyanus, P. lafii n. sp. from E. fuscoguttatus and N. epinepheli n. sp. from E. maculatus. The other three new species are P. robertsthomsoni n. sp. from Cephalopholis argus, C. cyanostigma and C. miniata, P. conorjonesi n. sp. from Cromileptes altivelis, and P. milleri n. sp. from Variola louti. Extensive examinations of other piscivorous fish species from the Great Barrier Reef have not revealed these six bucephalid species, which appear to be restricted at least to the host genera from which they are reported here.
