Two new species of terrestrial Isopoda (Crustacea,Oniscidea) from Ascension Island

A collection of eight species of terrestrial isopods from lava and cave sites on Ascension Island is described. Two species, Niambia longiantennata (Platyarthridae) and Elumoides coecus (Eubelidae), are described as new. Atlantoscia alceui Ferrara and Taiti (Philosciidae) is considered to be a junior synonym of A. floridana (Van Name) and the genus Ocelloscia Schultz and Johnson of Atlantoscia Ferrara and Taiti. At present the oniscidean fauna known from Ascension Island consists of 13 species.     

A new genus and species of terrestrial isopod from Malaysia (Crustacea,Oniscidea, Platyarthridae)

A new terrestrial isopod, Cephaloniscus sociabilis gen. nov., sp. nov., from Fraser Hill in central Malaysia, is described and illustrated. The new genus belongs to the family Platyarthridae and is distinguished from other members of the family by the characteristic structure of the cephalon. The specimens were collected from the nest of the termite Hospitalitermes sp. (near medioflavus Holmgren) together with the ant Centromyrmex hamulatus (Karavaiev).     

A new species and new records of terrestrial isopods from Sicily (Isopoda: Oniscidea)

In this paper three species of terrestrial isopods from Sicily are discussed. Spelaeoniscus coiffaiti and Cylisticus convexus are new to the Sicilian fauna. Sicilian specimens of Spelaeoniscus coiffaiti are examined and illustrated, and the biogeographical significance of this species in Sicily is discussed. Trichoniscus panormidensis is described as a new species, and the affinities are treated.     

Postmarsupial development of Atlantoscia floridana (van Name, 1940) (Crustacea,Isopoda, Oniscidea): the manca stages

In this paper we describe the postmarsupial development of the manca stages of Atlantoscia floridana (van Name, 1940). Ovigerous females were collected in Reserva Biológica do Lami, Porto Alegre, RS, Brazil and separately reared in small containers at 20°C (±1°C). After birth each newborn (manca I) was reared separately in order to observe the subsequent moults. In a period of about 12 h the animals underwent the first moult. The manca II stage lasts 9.16±1.57 days while manca III takes up a period of 9.96±1.05 days. Growth was observed through measurements of cephalothorax width. The three manca stages are described, illustrated and compared with the adults. The main distinguishing characteristics among mancas I, II and III are presented as well as the b/c and d/c co-ordinates of the noduli laterales.     

Considerations about the genus Pentoniscus Richardson, 1913 (Crustacea: Isopoda: Oniscidea) with description of a new species

The status of the neotropical genus Pentoniscus Richardson, 1913 is reconsidered and a diagnosis of this genus is given. It is shown that Pentoniscus Richardson, 1913 is a valid genus and not a synonym of Philoscia Latreille, 1804 as discussed by Schultz (1968). The type species, Pentoniscus pruinosus Richardson, 1913 is redescribed and for the first time figured in detail. A new species of Pentoniscus Richardson, 1913 is described from Costa Rica, Central America, which differs remarkably from its congeners in being unpigmented and blind.     

Three new genera of Banchinae (Hymenoptera: Ichneumonidae) from Central and South America

Three new genera and four new species of Banchinae are described from Central and South America: Terrylee gen. n., is described from Peru and Honduras to accommodate Terrylee olearius sp. n. and Terrylee peruensis sp. n. (type species: Terrylee peruensis sp. n.); Valdiviglypta gen. n. and Pristiboea gen. n. are described from Chile (type species: Valdiviglypta nimbus sp. n. and Pristiboea leiomano sp. n.). Terrylee and Pristiboea are placed in the tribe Atrophini, Valdiviglypta tentatively in the tribe Glyptini. All the three new genera are morphologically very distinctive and two have such character suites that they may not immediately be recognizable as banchines. By describing these three Neotropical genera from Chile, Honduras and Peru we aim to draw further attention to the considerable morphological variation within the ichneumonid subfamily Banchinae.     

Terrestrial isopods from the Oued Laou basin,north-eastern Morocco (Crustacea: Oniscidea), with descriptions of two new genera and seven new species

Thirty-four species of terrestrial isopods (Crustacea: Oniscidea) from the Oued Laou basin, in the Rif area of north-eastern Morocco, are recorded. One genus (Paractenoscia) and seven species (Trichoniscus microphthalmus, Paractenoscia cavernicola, Bathytropa rifensis, Soteriscus gibbosus, S. laouensis, Porcellio pseudornatus, and Eluma praticola) are described as new. The genus Soteriscus, unavailable according to article 13.3 of the International Commission on Zoological Nomenclature (ICZN), is here revalidated by choosing S. gaditanus as type species. Six species (Graeconiscus thermophilus, Ctenoscia minima, Platyarthrus parisii, Porcellio humberti, Porcellio flavocinctus and Eluma caelata) have been fully illustrated to facilitate their identifications. Ctenoscia dorsalis Verhoeff is considered to be a junior synonym of C. minima Dollfus. Porcellio ornatus from southern Spain is also figured for comparison with P. pseudornatus sp. nov. The composition and origin of the oniscidean fauna of the Rif region is briefly discussed.

On the South American species of the genus Meridiosignum (Crustacea: Isopoda: Asellota: Paramunnidae)

Meridiosignum undulatum n. sp. and M. disparitergum n. sp. are described from off the Río de la Plata estuary. These two new species are easily distinguished from other members of the genus Meridiosignum in having the lateral margins of pereonites 2 and 3 bilobed (the concavity is much more pronounced in M. disparitergum), and those of pereonite 4 produced into a single process. The terminal male instar of Meridiosignum menziesi (Winkler, 1994 Winkler, H. 1994. Paramunnidae (Crustacea: Isopoda: Asellota) from the Magellan Strait.. Zool J Linn Soc., 110: 243–296. [Crossref] , [Google Scholar]) is described, and this species is herein reported from the Beagle Channel and Puerto Deseado. All the species currently placed in Meridiosignum were found in shallow waters in the southern hemisphere, M. undulatum n. sp. and M. disparitergum n. sp. being the species recorded at the greatest depth (129 m).     

First record of the genus Agnara (Isopoda: Oniscidea) from Iran with descriptions of two new species

Terrestrial isopods of the genus Agnara Budde-Lund, 1908 have been recorded from Iran for the first time. Two new species, Agnara tarahomii n. sp. and Agnara haselii n. sp., are described and their diagnostic characters are figured. Agnara tarahomii is characterized by the shape of the male pleopod exopodite I with sinuous distal margin. Agnara haselii is distinguished by a setose area on the ventral margin of the male pereopod VII ischium and the sinuous distal margin of pleopod exopodite I.     

A new genus and two new species of Pudeoniscidae Lemos de Castro 1973 (Crustacea: Isopoda: Oniscidea) from Brazil

To date, the family Pudeoniscidae includes six species and three genera, Pudeoniscus, Brasiloniscus and Iansaoniscus, with distributions restricted to Brazil. Here, we redefine the family Pudeoniscidae based on the discovery of a new genus and two new species, Oxossioniscus pataxo sp. nov. and Oxossioniscus akoko sp. nov., from the Brazilian Atlantic forest in the state of Bahia, and on the examination of Pudeoniscus birabeni and Pudeoniscus obscurus. Moreover, P. obscurus is re-described and new records are provided for P. birabeni.

Two new species of Clinocentrus Haliday (Hymenoptera: Braconidae) from Argentina,with notes on South American species

The Argentine species of the genus Clinocentrus Haliday are revised. Two new species are described, Clinocentrus mamull sp. nov. and Clinocentrus roigi sp. nov., which represent the southernmost records of the genus in South America. Additionally Clinocentrus nigripectus Enderlein is redescribed and a key to known South American species is provided.     

Two new species of the genus Chilibathynella Noodt, 1963 and Onychobathynella bifurcata gen. et sp. nov (Crustacea: Syncarida: Parabathynellidae) from New South Wales,Australia

Two new species of the parabathynellid genus Chilibathynella Noodt, 1963 Noodt, W. 1963. Estudios sobre Crustaceos de aguas subterraneas, III. Crustacea Syncarida de Chile Central. Investig Zool Chilenas, 10: 151–167.  [Google Scholar] are described from Australia. Chilibathynella joshuai sp. nov. has a unique combination of morphological characters, which includes five-segmented antenna, no epipodite on thoracopod I, two setae on the endopod of the male thoracopod VIII, homonomous row of 17 spines on uropodal sympod, uropodal exopod with four distal spines and a flat anal operculum. Chilibathynella digitus sp. nov. has two exclusive characters: six teeth on the pars incisiva of the mandible and a large, elongated digitiform protuberance (resembling a finger) on the basipod of male thoracopod VIII. The species also displays a unique combination of morphological characters, which includes five-segmented antenna, no epipodite on thoracopod I, no outer marginal seta on the first and second segments of the endopod of thoracopod I to VII, two setae on the endopod of the male thoracopod VIII, homonomous row of 12 spines on uropodal sympod, uropodal exopod with three distal spines and an unprotruded anal operculum. The two new species extend the distribution of the Chilibathynella genus in Australia from Victoria to New South Wales. A new genus and species of the family Parabathynellidae, Onychobathynella bifurcata gen. nov. sp. nov., is described from New South Wales, Australia. The new genus displays an evolutionary novelty, for Parabathynellidae and the entire group of Bathynellacea: the antennule, antenna, thoracopods, pleopod I and uropod have setae that are strong, thick, short, barbed and claw-like. This new genus is the first in the family without smooth setae on the antennule and antenna. The new genus also has a combination of characters that makes it unique in Parabathynellidae: the antennule is eight-segmented like Octobathynella Camacho and Hancock, 2010 Camacho, AI and Hancock, P. 2010. A new record of Parabathynellidae (Crustacea, Bathynellacea) in Australia: a new genus and species from New South Wales. J Nat Hist, 44(17–18): 1081–1094. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]; the antenna is five-segmented; the labrum has 20 teeth; the exopod of thoracopod I to VII has only one segment; the endopod lacks dorsal setae on the first segment and the epipod is absent from thoracopod I; first pleopods are present and resemble two barbed curved claws; there are 18 bifid spines on the sympod, two spines and four setae resembling strong barbed claws on the endopod and six robust setae on the exopod of the uropod.     

The Neotropical genus Cyriocosmus Simon, 1903 and new species from Peru,Brazil and Venezuela (Araneae: Theraphosidae: Theraphosinae)

Cyriocosmus peruvianus sp. nov., C. itayensis sp. nov., C. aueri sp. nov., C. giganteus sp. nov. from Peru, Loreto region, C. hoeferi sp. nov. from Brazil, C. williamlamari sp. nov. and C. nicholausgordoni sp. nov. from Venezuela are described, illustrated, diagnosed and both sexes, if known, keyed. New Peruvian species can be distinguished from all congeners, except C. bertae Pérez-Miles, 1998 and C. pribiki Pérez-Miles and Weinmann, 2009, by the uniformly coloured carapace and abdomen without stripes and by the short paraembolic apophysis in male palpal bulb. The female of Cyriocosmus ritae Pérez-Miles, 1998 is described for the first time from a known Peruvian population near Iquitos.     

Leptandria gen.n., a monophyletic group of Neotropical aleocharine Staphylinidae (Coleoptera)

Based on external structural features, especially those of the mouthparts, and male and female genitalia, the aleocharine staphylinid genus Leptandria, new genus, is proposed and diagnosed. Three new species are also described, L. ashei, L. tishechkini and L. ecitophila, with a key to differentiate them and numerous illustrations of diagnostic features presented.
