A formação dos oostegitos em Porcellio dilatatus Brandt (Crustácea, Isopoda, Oniscidea) em laboratório Zoologia
Loyola e Silva,Jayme de; Coraiola,Maria Aparecida Sídor.
Woodlice were reared in laboratory in the environmental climate of the city of Curitiba, Brazil, with the purpose of getting to know the process of formation of oostegites. Two kinds of cultivation were adopted: natural populations to be controlled were kept in small glass aquariums resembling the natural environment; and, new-bom woodlice were raised each one isolated in small plastic receptacles, with a special diet until two years old or over. When adults, after recognizing their sexes, males and females were put together to copulate during one or more days, and some of the females were fertilized. After 30 days, the fertilized females realized ecdise and acquired oostegites. The complete process (copulation, fecundation, incubation and birth) occurred...

A new genus of Oniscidea from South America and a phylogenetic analysis of related genera (Crustacea: Isopoda: Philosciidae) Naturalis
Leistikow, Andreas.
In a collection of terrestrial isopods from Venezuela, a distinct species was identified which does not fit any of the known genera. Therefore, a new taxon Metaprosekia gen.n. is instituted to accomodate the new species. An analysis of its morphological characters revealed a close relationship to the genus Prosekia Vandel, 1968 and allied genera. The phylogeny of this group is discussed and one of its poorly known representatives, Xiphoniscus mirabilis Vandel, 1968 is redescribed on the basis of the type material.

A new species of Benthana (Crustacea: Isopoda: Philosciidae) from southern Brazil Zoologia
Sokolowicz,Carolina C.; Araujo,Paula B.; Boelter,Juliana F..
A new species of Benthana Budde-Lund, 1908 is described from southern Brazil. Benthana cairensis sp. nov. is distinguished from the other species in the genus by having 17 aesthetascs on the antennula and the elongated male pleopod 1 exopod with a lobe on the inner lateral margin and up to six setae on the outer lateral margin. The new species most resembles B. olfersii (Brandt, 1833), but may be distinguished by lacking the lobe with six setae on the internal margin of the proximal extremity of the merus of pereiopod 7. Furthermore, we include B. olfersii in the subgenus Benthanoscia based on the examined material as described herein.

First record of Wolbachia in South American terrestrial isopods: prevalence and diversity in two species of Balloniscus (Crustacea, Oniscidea) Genet. Mol. Biol.
Almerão,Mauricio Pereira; Fagundes,Nelson Jurandi Rosa; Araújo,Paula Beatriz de; Verne,Sébastien; Grandjean,Frédéric; Bouchon,Didier; Araújo,Aldo Mellender.
Wolbachia are endosymbiotic bacteria that commonly infect arthropods, inducing certain phenotypes in their hosts. So far, no endemic South American species of terrestrial isopods have been investigated for Wolbachia infection. In this work, populations from two species of Balloniscus (B. sellowii and B. glaber) were studied through a diagnostic PCR assay. Fifteen new Wolbachia 16S rDNA sequences were detected. Wolbachia found in both species were generally specific to one population, and five populations hosted two different Wolbachia 16S rDNA sequences. Prevalence was higher in B. glaber than in B. sellowii, but uninfected populations could be found in both species. Wolbachia strains from B. sellowii had a higher genetic variation than those isolated from...

Growth curve of Atlantoscia floridana (van Name) (Crustacea, Isopoda, Philosciidae) from a Brazilian Restinga Forest Zoologia
Araujo,Paula Beatriz; Bond-Buckup,Georgina.
The terrestrial isopod Atlantoscia floridana (van Name, 1940) occurs from the U.S.A. (Florida) to Brazil and Argentina. In the southernmost Brazilian State, Rio Grande do Sul, the species is recorded in many localities, in urban and in non-urban areas. The growth curve of Atlantoscia floridana based on field data is presented. The specimens were sampled from April, 2000 to October, 2001 at the Reserva Biológica do Lami (RBL), Rio Grande do Sul. Captured individuals were sexed and had their cephalothorax width measured, with the data analyzed with von Bertalanffy's model. The growth curves for males and females are described, respectively, by the equations: Wt = 1.303 [1 - e-0.00941 (t + 50.37)] and Wt = 1.682 [1 - e-0.00575 (t + 59.13)]. The curves showed...

Increased genetic diversity in Greek populations of the genus Ligidium (Crustacea: Isopoda: Oniscidea) revealed by RFLP analysis of mtDNA segments Naturalis
Klossa-Kilia, E.; Kilias, G.; Sfenthourakis, S..
We investigated mtDNA genetic differentiation and the phylogenetic relationships of 11 populations of the oniscidean genus Ligidium. We studied nine populations from Greece, assigned to three nominal species (L. euboicum, L. germanicum and L. beieri), and two from central Europe (L. germanicum and L. hypnorum), applying RFLP analysis of two mtDNA segments (12S rDNA and 16S rDNA) amplified by PCR. The analysis revealed seven monomorphic and four polymorphic populations, and 17 different haplotypes, each one present in one population only. Several restriction enzymes produced population specific patterns, enabling discrimination among the different populations. The estimated net nucleotide divergence between populations ranges from 1.06 to 16.52%, while the...

Landpissebedden van de Ooijpolder: deel 1. verspreiding (Crustacea: Isopoda: Oniscidea) Naturalis
Wijnhoven, H..
Terrestrial isopods of the Ooijpolder: part 1. distribution (Crustacea: Isopoda: Oniscidea) The distributions and habitats of woodlice were investigated in ‘the Ooijpolder’, also named ‘the Ooij’. The area of approximately 41 square kilometers is located along the river Waal, east of Nijmegen, Province of Gelderland, The Netherlands (fig. 2). In total 1464 squares of 100 x 100 m (utm) (fig. 9) were sampled by hand from 1991 up to 1998 (Table 1). On a recording form (fig. 5) five first order habitats were distinguished (Table 2): 1. The river foreland is flooded on average for a few weeks once every winter or spring, and is bounded by a winterdyke. 2. The sandy river dunes in the flood plains are inundated only very occasionally. Three old brickstone...

Naamlijst van de Nederlandse landpissebedden (Crustacea: Isopoda: Oniscidea) Naturalis
Berg, M.P..
Checklist of Dutch woodlice (Crustacea: Isopoda: Oniscidea). An updated checklist for the terrestrial isopods of The Netherlands is presented. Four species, Armadillo officinalis, Eluma purpurascens, Miktoniscus patiencei, and Trichoniscoides sarsi are new to the woodlice fauna of The Netherlands compared with to the previous checklist, while two species, Ligia exotica and Halophiloscia couchii, were deleted from the checklist due to lack of evidence. The updated list will be used in the project 'The woodlice of the Netherlands' of the European Invertebrate Survey - The Netherlands.

Terrestrial isopod diversity in the subtropical neotropics: Itapuã State Park, southern Brazil Iheringia, Sér. Zool.
Almerão,Maurício P.; Mendonça Jr.,Milton de S.; Quadros,Aline F.; Pedó,Ezequiel; Silva,Luiz G. R.; Araujo,Paula Beatriz.
We analysed species abundance and composition during one year of sampling at Itapuã State Park, a conservation unit in the State of Rio Grande do Sul, southern Brazil. Samples were collected monthly from May 2003 to April 2004 along a 4 km forest trail divided in three transects along the slopes of a small hill. Terrestrial isopods were hand searched by three people for 40 minutes at two sampling sites along each transect, summing 240 minutes of sampling effort per transect per month. Six species distributed in six families were found. The collector curve stabilised when half the samples were taken, demonstrating sampling sufficiency: analytical estimates did not predict more species to be found in the trail. Atlantoscia floridana (van Name, 1940) was...
