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 taxonomic revision of the European, Mediterranean and NW. African species generally placed in Sphaeroma Bosc, 1802 (Isopoda: Flabellifera: Sphaeromatidae) Naturalis
Jacobs, B.J.M..
The European, Mediterranean and NW. African species usually assigned to the genus Sphaeroma are revised. The genus Sphaeroma as understood so far has been divided into two genera: Sphaeroma s.s. and Lekanesphaera Verhoeff, 1943. Keys to the three species of Sphaeroma and the thirteen species of Lekanesphaera are given. Two new species are described viz., L. glabella (from Madeira) and L. terceirae (from Terceira, Azores) and the synonymy of known species is provided.

An assemblage of terrestrial isopods (Crustacea) in southern Brazil and its contribution to leaf litter processing Zoologia
Quadros,Aline F.; Araujo,Paula B..
We present an assemblage of terrestrial isopods in Parque Estadual de Itapuã, southern Brazil, and estimate the contribution of two species to the leaf litter processing. After one year of sampling, we obtained 3748 individuals of six species and four eco-morphologic groups (in order of abundance): Balloniscus glaber Araujo & Zardo, 1995, Atlantoscia floridana (van Name, 1940), Pseudodiploexochus tabularis (Giambiagi de Calabrese, 1939), Trichorhina sp., Alboscia itapuensis Araujo & Quadros, 2005 and Novamundoniscus gracilis Lopes & Araujo, 2003. Total monthly density corresponded to 368 individuals per square meter. The species A. itapuensis and N. gracilis represented less than 1% of total individuals. All the others showed...

Aspects of the evolution and biogeography of stygobiontic Isopoda (Crustacea: Peracarida) Naturalis
Wägele, Johann-Wolfgang.
The evolution of the stygobiontic isopods is discussed correlating the phylogenetic system with biogeography. All stygobiontic isopods probably are derived from remote marine ancestors. The colonization of subterranean aquatic biotopes occurred in two ways: (1) via the coastal groundwater in the case of the Microparasellidae, Gnathostenetroididae, Stenetriidae, and in Cyathura (Stygocyathura), (2) in most families, however, via epigean freshwater ancestors. Ancient freshwater isopods that must already have existed before the Cretaceous and whose stygobiontic phylogenetic lines partly must have existed before the opening of the Atlantic are the Aselloidea, Calabozoida, Phreatoicidea, and probably also the Protojaniridae. In the course of Cretaceous and...

Biologia reprodutiva de Ligia exotica (Crustacea, Isopoda, Ligiidae) em Rio Grande, Rio Grande do Sul, Brasil Iheringia, Sér. Zool.
Lopes,Elis R. C.; Blasina,Juliana R.; Dumont,Luiz F. C.; D'Incao,Fernando.
Com o objetivo de elucidar alguns aspectos da biologia reprodutiva de Ligia exotica Roux, 1828, duas populações que habitam o Estuário da Lagoa dos Patos (Molhe Oeste da Barra de Rio Grande e Ilha do Leonídeo) foram analisadas. A amostragem foi realizada quinzenalmente entre o verão/2003 e o inverno/2004. Os animais foram coletados manualmente durante uma hora. O período reprodutivo da espécie foi registrado para os meses de outubro a junho. Nenhuma fêmea ovígera foi observada de julho a setembro. No Molhe Oeste da Barra de Rio Grande, 5.376 indivíduos foram capturados (1.494 juvenis, 1.748 machos e 2.134 fêmeas, das quais 245 eram ovígeras). A proporção sexual estimada foi 0,78 (M:F). Para a análise da fecundidade, 178 fêmeas ovígeras com o marsúpio...

Checklist of the terrestrial isopods of the new world (Crustacea, Isopoda, Oniscidea) Zoologia
Leistikow,Andreas; Wägele,Johann Wolfgang.
A check-list of all the American Oniscidea known to the authors and their quotation in literature is presented. The species account comprises notes on species' distribution and a revised synonymy. As far as possible comments on taxonomic problems are given. The species are ascribed to the families which are commonly recognised, despite many of them are paraphyletic constructions. This check-list should support the work of both ecologists and taxonomist when dealing with New World Oniscidea.

Community structures of soil animals and survival of land snails on an island of the Ogasawara Archipelago PAB
Hasegawa,Motohiro; Sugiura,Shinji; Ito,Masamichi T.; Yamaki,Aska; Hamaguchi,Keiko; Kishimoto,Toshio; Okochi,Isamu.
On Chichijima, one of the Ogasawara (Bonin) Islands located in the Western Pacific Ocean, land snails have declined, the suggested cause being predation pressure by an invasive flatworm (Platydemus manokwari). Soil fauna were investigated in areas where the snail survives, and where it has become extinct. Much of the fauna, dominated by introduced earthworms and ants, was undiminished, however, one undescribed but endemic carabid (Badister sp.), which selectively feeds on land snails, was absent in snail-extinct areas. The invasive flatworm P. manokwari has been reported to feed also on the carcasses of earthworms, as well as on live snails, and is therefore expected to occur in most parts of Chichijima Island. Among other groups, the density of isopods...

Cylisticus convexus, een in Nederland zeldzame synantrope landpissebed (Crustacea: Isopoda: Oniscoidea) Naturalis
Berg, M.P.; Wijnhoven, H.; Tempelman, D..
Cylisticus convexus, a rare synanthropic woodlouse in The Netherlands (Crustacea: Isopoda: Cylisticidae) Until recently, the occurrence of Cylisticus convexus (De Geer, 1778) in the Netherlands was uncertain. The only certain old record dates from March 1927, when the species was collected at the coal-shed of the Zoological Museum at Amsterdam. During the last years, two specimens have been collected on semi-natural sites. Both were found on a dike, one near Everdingen, in the province of Gelderland, and one near Ritthem, in the province of Zeeland. These are the first records of C. convexus in the field. Yet the species certainly is very rare in The Netherlands. The most important morphological characteristics of the species are described and...

De brede pissebed Porcellio dilatatus komt nog vrijlevend voor in Nederland (Isopoda: Porcellionidae) Naturalis
Berg, M.P.; Noordwijk, C.G.E. van; Kruithof , A..
De provincie Limburg is relatief goed onderzocht op het voorkomen van landpissebedden. De vele onderzoeken hebben in een lijst van 25 soorten geresulteerd, waaronder een aantal dat grotendeels tot deze provincie beperkt is. De brede pissebed komt onder natuurlijke omstandigheden alleen in Zuid-Limburg voor en is in de rest van het land verspreid in tropische kassen en soms in huis aan te treffen. Sinds de oprichting van de EIS-werkgroep Bodemfauna in 1990 werd ze ondanks goed zoeken niet meer vrijlevend in Limburg waargenomen. De laatste waarneming dateerde alweer van 1981. Daar is nu verandering in gekomen. In materiaal verzameld in kalkgraslanden in Zuid-Limburg in de zomer en herfst van 2005 werd P. dilatatus gevonden. Daarna is ze ook op andere...

De invloed van recente overstromingen op het verspreidingspatroon van de pissebed Eluma purpurascens in Zeeland (Crustacea: Isopoda: Oniscoidea) Naturalis
Berg, M.P.; Kroon, A..
The influence of recent inundations on the distribution pattern of the isopod Eluma purpurascens in the province of Zeeland (Crustacea: Isopoda: Oniscoidea) Small scale mapping of Eluma purpurascens Budde-Lund, 1885 in the province of Zeeland revealed a remarkable distribution pattern. The species proved to be absent in parts which have been inundated during and after the second world war. This study shows that for the interpretation of distribution patterns the history of the study area should be considered.

De zeepissebed Uromunna spec, de eerste waarneming van de familie Munnidae in Nederland (Isopoda) Naturalis
Faasse, M.A.; Ligthart, A.H.M..
Onze fauna verandert en de mariene fauna is daarop geen uitzondering. Zuidelijke soorten koloniseren onze kustwateren en exotische soorten worden door de mens aangevoerd. Voor sommige soorten is niet duidelijk waarom ze hier opduiken. De sterk veranderende kustbiotopen spelen ongetwijfeld eveneens een rol. Een niet-aflatende stroom onverwachte soorten, soms zelfs behorend tot nieuwe genera en zelfs families maken faunistisch onderzoek in de kustwateren verrassend en boeiend. In het kader van een inventarisatie van kreeftachtigen in het Deltagebied werden in de Oosterschelde bij Zierikzee verscheidene kleine monsters genomen van diverse substraten. De monsters van roodwieren bevatten een aantal opmerkelijke soorten. Dit artikel behandelt Uromunna spec., een...

Distribution pattern of crustacean ectoparasites of freshwater fish from Brazil. Repositório Alice
TAVARES-DIAS, M.; DIAS-JÚNIOR, M. B. F.; FLORENTINO, A. C.; SILVA, L. M. A.; CUNHA, A. C. da.
The purpose of this study was to use the informations relating to parasite crustaceans species that was published over the course of one century (1913 to 2013), in order to search for infestation and distribution patterns among these ectoparasites in Brazilian freshwater fish species. This search was carried out on 445 samples of 119 host fish of 27 families within the orders Characiformes, Perciformes, Clupeiformes, Mugiliformes, Osteoglossiformes, Symbranchiformes, Tetraodontiformes and Siluriformes from various regions of Brazil. We organized different host-parasite systems into matrices grouping species at different taxonomic and infestation levels and according to host parameters. Five families of parasites (Ergasilidae, Argulidae, Lernaeidae,...

Een opmerkelijke waarneming van de zeldzame landpissebed Porcellium conspersum in Overijssel (Isopoda: Trachelipodidae) Naturalis
Berg, M.P.; Dias, A.T.C.; Oosten, R. van; Bellone, D..
Tijdens het verzamelen van Ligidium hypnorum in het Agelerbroek, ten zuidoosten van Ootmarsum, vonden de auteurs op 1 november 2011 een kleine populatie van Porcellium conspersum. Deze fraaie soort was tot nu toe alleen uit Zuid-Limburg bekend, waar hij tot de zeldzame pissebedden gerekend moet worden. Met deze eerste vondst voor Overijssel is de verspreidingsgrens van P. conspersum in Nederland met 150 km naar het noorden verschoven. Naar verwachting komt de soort op meer locaties langs de oostgrens voor.

Eluma purpurascens, new for the Dutch fauna (Crustacea: Isopoda: Oniscoidea). The first Dutch specimen of Eluma purpurascens was found on 29 April 1994 on the Kaloot, east of Vlissingen, in the south-western province of Zeeland. One year later the species proved to be locally common along the southern coast of the Oosterschelde and three years later several hundreds mature and immature specimens were found along the southern coast of the Westerschelde and along the coast of the North Sea. So far, the species has not been found on the isle of Schouwen-Duiveland. It seems to be almost absent inland although not all sites where this species might occur have yet been visited. In this paper the morphology of Eluma purpurascens is illustrated, and some notes on...
