Three new species of the genus Philopteroides Mey, 2004 (Phthiraptera,Ischnocera, Philopteridae) from?New?Zealand

We describe and illustrate three new species of chewing lice in the genus Philopteroides parasitic on passerines (Order Passeriformes, families Acanthizidae, Rhipiduridae and Petroicidae) from New Zealand. They are: Philopteroides pilgrimisp. n. from Gerygone igata igata; Philopteroides fuliginosussp. n. from Rhipidura fuliginosa placabilis and Rhipidura fuliginosa fuliginosa; and Philopteroides macrocephalussp. n. from Petroica macrocephala macrocephala and Petroica macrocephala dannefaerdi. The identity of Docophorus lineatus Giebel, 1874 is discussed based on its morphology and host association. We also transfer Tyranniphilopterus beckeri to the genus Philopteroides, and provide a key to identify adults of 12 of the 13 species now included in Philopteroides.     

Gastrocopta (Mollusca,Gastropoda, Pupillidae) in?the?Pilbara region of Western Australia

Six species of Gastrocopta have been identified from the Pilbara region, Western Australia, by means of comparative analyses of shell and mtDNA variation. Three of these species, Gastrocopta hedleyi, Gastrocopta larapinta and Gastrocopta servilis, have been recorded in the Pilbara for the first time. Gastrocopta sp. CW1 is probably new to science and might be endemic to the region. By contrast, Gastrocopta hedleyi, Gastrocopta larapinta and Gastrocopta mussoni are shown to be widespread.     

Description of a new species of Distenia (Coleoptera,Disteniidae, Disteniini) from Southeastern China,with?records and diagnoses of similar species

A new species, Distenia orientalis sp. n. is described from Southeastern China. It was misidentified as Distenia gracilis (Blessig, 1872) but can be separated from the latter by the color of antennae and legs, structure differences on scape, maxillary palp, pronotum, tibiae, punctures on elytra, etc. Three related species are carefully diagnosed and treated.     

Population monitoring of the endangered New?Zealand spider,

The endangered New?Zealand widow spider, Latrodectus katipo, is believed to have undergone marked population decline over the last 30 years, but as monitoring methods are time- and labour-intensive, and require observers to have a high level of experience, the current status of many populations is unknown. We investigated the use of artificial cover objects (ACOs) as an alternative monitoring tool for L. katipo at three sites at Himatangi Beach, Manawatu, New?Zealand, from late 2004 through to mid-2005. Occupancy rates of the ACOs were compared with population densities obtained from habitat searches, to assess their efficacy as a monitoring tool. Numbers of the introduced spider, Steatoda capensis, which may be a competitor of L.?katipo, were also recorded during habitat searches. ACOs were reliable monitoring tools, with occupancy rates higher at the site with the highest L.?katipo population density. Latrodectus katipo populations were found to have highly female biased sex-ratios, with a longer breeding season at Himatangi than reported previously at other sites. Steatoda capensis exists at much higher population densities than L.?katipo at Himatangi. However, fluctuations in the populations of the two species appear to be unrelated. ACOs could be used as a non-destructive monitoring tool for many other arachnid species.     

New records of the Late Carboniferous ammonoid genus <Emphasis Type="Italic">Eoshumardites</Emphasis> in the Kolyma–Omolon Region,and notes on the evolution of Eoshumarditidae

A new species, Eoshumardites popowi Kutygin sp. nov., is described from the Upper Carboniferous of the upper reaches of the Paren’ River in the Gizhiga Province of the Kolyma–Omolon Region. The ontogeny of the sutural and shell morphology of the new species is described. In the level of sutural organization, E. popowi occupies an intermediate position between E. lenensis (Popow) and E. sublenensis Klets. It has been suggested that Eoshumardites evolved from the genus Syngastrioceras rather than Aktubites and, on this basis, a new monotypic endemic family, Eoshumarditidae, has been proposed. This family existed in the Kasimovian synchronously with members of the family Parashumarditidae.     

C15 acetogenins and terpenes of the dictyoceratid sponge Spongia zimocca of Il Rogiolo: A case of seaweed-metabolite transfer to,and elaboration within,a sponge?

• 1.1. In the narrow Mediterranean area of Il Rogiolo, the acetates of the secondary alcohols of β-chamigrene (−)-1b, branched lauroxepane (−)-2b, and isopimarane (+)-3b are found in the dictyoceratid sponge Spongia zimocca, whereas the corresponding free alcohols (+)-1a, (−)-2a, and probably also (+)-3a, are found in the red seaweed Laurencia microcladia.
• 2.2. No one of these acetylated metabolites could be detected either in this seaweed or in the global algal mass of Il Rogiolo.
• 3.3. Terpenes bearing tertiary alcoholic functionalities of either L. microcladia (−)-4E, (−)-4Z or another red seaweed of the same area, Sphaerococcus coronopifolius [(+)-5, (−)-6], are found unaltered also in S. zimocca.
• 4.4. These findings imply transfer of the hydroxyl-bearing metabolites from the seaweeds to the sponge and it is tempting to speculate that the secondary alcoholic function is acetylated in the sponge while tertiary alcohols and the secondary alcohol (+)-7 escape acetylation, the first ones as sterically-hindered alcohols and the latter one as a sponge metabolite residing in a special cell compartment.

     

Review of the genus Tinissa Walker, 1864 (Lepidoptera,?Tineidae,Scardiinae) from China,with?description of?five new species

The genus Tinissa Walker is reviewed for China. Seven species are recognized, of which Tinissa apicimaculata sp. n., Tinissa conchata sp. n., Tinissa connata sp. n.,Tinissa leguminella sp. n. and Tinissa spirella sp. n. are described as new; and Tinissa insularia Robinson, 1976 is newly recorded from China. Photographs of the adults and illustrations of the genitalia are given. A key to all the known Chinese species and a distribution map of Tinissa in China are included.     

How unique is the tiger beetle fauna (Coleoptera,Cicindelidae) of the Balkan Peninsula?

The tiger beetle fauna of the Balkan Peninsula is one of the richest in Europe and includes 19 species or 41% of the European tiger beetle fauna. Assembled by their biogeographical origins, the Balkan tiger beetle species fall into 14 different groups that include, Mediterranean, Middle Oriental, Central Asiatic, Euro-Siberian, South and East European, Pannonian-Sarmatian, West Palaearctic, Turano-European and Afrotropico Indo-Mediterranean species. The Mediterranean Sclerophyl and the Pontian Steppe are the Balkan biogeographical provinces with the highest species richness, while the Balkan Highlands has the lowest Cicindelidae diversity. Most species are restricted to single habitat types in lowland areas of the Balkan Peninsula and only Calomera aulica aulica and Calomera littoralis nemoralis occur in respectively 3 and 4 different types of habitat. About 60% of all Balkan Cicindelidae species are found in habitats potentially endangered by human activity.     

A neotype designation for the bone-skipper Centrophlebomyia anthropophaga (Diptera,Piophilidae, Thyreophorina), with a review of the?Palaearctic?species?of Centrophlebomyia

The European bone-skippers (Diptera: Piophilidae: Thyreophorina), long considered extinct, have recently been the object of much interest by dipterists after their unexpected rediscovery. Considerable faunistic work has been done on these flies in recent years. However, some nomenclatural and taxonomic issues still require attention. A neotype is designated for Thyreophora anthropophaga Robineau-Desvoidy, 1830 (now in the genus Centrophlebomyia Hendel, 1903) to fix the identity of this nominal species. Centrophlebomyia anthropophaga is recognized as a valid species. It is described and illustrated in detail, and information on its preimaginal instars is provided for the first time. Four Palaearctic species of Centrophlebomyia are recognized and reviewed and a key is provided for their identification. Centrophlebomyia orientalis Hendel, 1907 from northern India, is removed from synonymy with Centrophlebomyia anthropophaga and recognized as a valid species of Centrophlebomyia, stat. r. The nominal genus Protothyreophora Ozerov, 1984 is considered a junior synonym of Centrophlebomyia, syn. n.     

A new species of Lathrolestes (Hymenoptera,Ichneumonidae) from Ecuadorian Amazonia,with?a?key?to the Neotropical species of the genus

Here we describe and illustrate a new parasitoid wasp species, Lathrolestes gauldi sp. n. from the lowland rainforest of eastern Ecuador and provide a key to the Neotropical species of the genus. This is the first record of the subfamily Ctenopelmatinae from Ecuador.     

Taxonomy of new relatives of Onthophagus?catenatus Lansberge, 1883 from New Guinea (Coleoptera,?Scarabaeidae,Scarabaeinae)

Four new taxa from New Guinea are proposed in the dung beetle genus Onthophagus Latreille, 1802, all in the operational group of Onthophagus catenatus Lansberge, 1883. The group is discussed, defined, and the five taxa included are listed, keyed, and diagnosed. Three new species are described: Onthophagus abmisibilus (from West New Guinea, Indonesia), Onthophagus kokodanus, Onthophagus kokosquamatus (both from Papua New Guinea). One new species comprises a lowland and an upland subspecies: Onthophagus kokodanus kokodanus and kokodanus hagenaltus (both in Papua New Guinea).     

Leishmania (Viannia) naiffi: rare enough to be neglected?

In the Brazilian Amazon, American tegumentary leishmaniasis (ATL) is endemic and presents a wide spectrum of clinical manifestations due, in part, to the circulation of at least seven Leishmania species. Few reports of Leishmania (Viannia) naiffi infection suggest that its occurrence is uncommon and the reported cases present a benign clinical course and a good response to treatment. This study aimed to strengthen the clinical and epidemiological importance of L. (V.) naiffi in the Amazon Region (Manaus, state of Amazonas) and to report therapeutic failure in patients infected with this species. Thirty Leishmania spp samples isolated from cutaneous lesions were characterised by multilocus enzyme electrophoresis. As expected, the most common species was Leishmania (V.) guyanensis (20 cases). However, a relevant number ofL. (V.) naiffi patients (8 cases) was observed, thus demonstrating that this species is not uncommon in the region. No patient infected withL. (V.) naiffi evolved to spontaneous cure until the start of treatment, which indicated that this species may not have a self-limiting nature. In addition, two of the patients experienced a poor response to antimonial or pentamidine therapy. Thus, either ATL cases due to L. (V.) naiffi cannot be as uncommon as previously thought or this species is currently expanding in this region.     

The New Caledonian genus Caledonotrichia Sykora (Trichoptera,Insecta) reviewed,with?descriptions?of?6?new species

The New Caledonian endemic hydroptilid genus Caledonotrichia Sykora (Trichoptera) is reviewed and 6 new species are described: Caledonotrichia bifida, Caledonotrichia capensis, Caledonotrichia minuta, Caledonotrichia ouinnica, Caledonotrichia sykorai and Caledonotrichia vexilla. Together with the established species for which revised diagnoses are given, these raise to 11 the number of species known in this genus. The new species, females of 3 species, and several unusual larval cases are examined and described for further insight into relationships of this enigmatic genus. A key to species is provided.     

Isolation and Characterization of the New Mosaic Filamentous Phage VFJ Φ of Vibrio cholerae

Filamentous phages have distinguished roles in conferring many pathogenicity and survival related features to Gram-negative bacteria including the medically important Vibrio cholerae, which carries factors such as cholera toxin on phages. A novel filamentous phage, designated VFJΦ, was isolated in this study from an ampicillin and kanamycin-resistant O139 serogroup V. cholerae strain ICDC-4470. The genome of VFJΦ is 8555 nucleotides long, including 12 predicted open reading frames (ORFs), which are organized in a modular structure. VFJΦ was found to be a mosaic of two groups of V. cholerae phages. A large part of the genome is highly similar to that of the fs2 phage, and the remaining 700 bp is homologous to VEJ and VCYΦ. This 700 bp region gave VFJΦ several characteristics that are not found in fs2 and other filamentous phages. In its native host ICDC-4470 and newly-infected strain N16961, VFJΦ was found to exist as a plasmid but did not integrate into the host chromosome. It showed a relatively wide host range but did not infect the classical biotype O1 V. cholerae strains. After infection, the host strains exhibited obvious inhibition of both growth and flagellum formation and had acquired a low level of ampicillin resistance and a high level of kanamycin resistance. The antibiotic resistances were not directly conferred to the hosts by phage-encoded genes and were not related to penicillinase. The discovery of VFJΦ updates our understanding of filamentous phages as well as the evolution and classification of V. cholerae filamentous phage, and the study provides new information on the interaction between phages and their host bacteria.
