A taxonomic revision of the genus Ocyale Audouin, 1826 in Africa (Araneae: Lycosidae)

The taxonomy of the African representatives of the wolf spider genus Ocyale is revised. Fundamental taxonomic problems were encountered which resulted in confusion in the literature between Ocyale and Pisaura and thus potential instability of the type genus of the family Pisauridae. For reasons of taxonomic stability, a new type species for Ocyale is proposed here: O. neatalanta. Besides the type species, O. dewinterae n.sp., O. discrepans Roewer, 1960, O. grandis n.sp. and Ocyale guttata Karsch, 1878, are described and an identification key is provided. Ocyale spissa (Lenz, 1895) proved to be a junior synonym of O. guttata. Ocyale maculata (L. Koch, 1875), O. spissides Strand, 1907, O. fera Strand, 1908, O. ingenua (Karsch, 1879) and O. conspersa Karsch, 1879, were found to be either nomina dubia or incertae sedis.     

Diversity of Salticidae (Arachnida: Araneae) in the historical and natural reserve ‘Martín García Island’, Argentina

From Martín García Island were collected 975 jumping spiders, from five environments, using beating net and manual sampling methods. Saitis variegatus Mello-Leitão, 1941 was the most abundant (24.62%). The sandy xerophilous forest had the highest species richness (23 morphospecies) and jungle showed the greatest spider abundance (n: 384). The sandy area was the least diverse and the last in relative abundance. Salticids represented 16% of the species recorded from Argentina, and the second largest family registered. The spider fauna found could be similar to that of the Southern Brasilian region, as occurs with scorpions. Two genera and two species are new records for Argentina. In addition, three new species of jumping spiders, as well as the discovery of the unknown male and female of two species, were registered. There was no record of cosmopolitan spiders or those with a large distribution range on the Island.     

A new earthworm genus Nouraguesia gen. nov. from French Guiana with description of two new species (Oligochaeta,Glossoscolecidae)

Nouraguesia gen. nov., consisting of three species, is described from Eastern Amazonia. Species belonging to this genus are middle-sized earthworms inhabiting, based on our experience, decomposing tree logs and space filled with detritus between leaf-axils and trunk (e.g. in some palm species). The new genus is morphologically similar to the genus Andiorrhinus, but differs from it by the presence of numerous caeca encircling the intestine in segment 27. The three species belonging to the newly established genus are known from state Amapa in Brazil (N. amaparis (Righi, 1971)); and French Guiana (N. parare sp. nov., N. souadae sp. nov.).     

Three new species of Benthana Budde-Lund (Isopoda, ‘Philosciidae’) from Brazil

Three new species of Benthana Budde-Lund, 1908 are described from material collected near São Fancisco de Paula, a town in the north-east of the southernmost Brazilian State, Rio Grande do Sul (RS). The new species are: Benthana serrana sp. nov., Benthana trinodulata sp. nov. and Benthana araucariana sp. nov. (from Araucaria Forest). The presence of more than one nodulus lateralis on coxal plate VII, a characteristic not previously known in the genus, is reported. New occurrences of B. picta (Brand, 1833) and B. taeniata (Araujo and Buckup, 1994) are also recorded. A method is given for defining the shape of the exopod of pleopod 1 of the male based on morphometry.     

A new polychaete genus and species of the Kongsfjorden,Spitsbergen, Svalbard

Glyphochaeta laudieni, a new genus and species of the “Spionidae”, is described from the Arctic. The specimens were collected from the Kongsfjorden, Spitsbergen, Svalbard, in a marine grotto. Glyphochaeta laudieni was associated with colonies of unidentified Bryozoa. This new genus and species is characterized by a prostomium with frontal horns, the absence of branchiae and sabre chaetae, and the presence of grooved spines which replace hooded hooks in some chaetigers of the middle body region. These spines are associated with glandular organs situated in neuropodia. The significance of characters for determining the systematic position of Glyphochaeta within “Spionidae” is discussed. Glyphochaeta laudieni is probably related to Pygospio elegans.     

Winter-active wolf spiders (Araneae: Lycosidae) in thermal habitats from western Romania

Shores of channels with thermal water provide an adequate microclimate for maintaining wolf spiders in activity during winter. Of the spiders collected after the winter survey of 22 thermal habitats from western Romania, 93.02% were juveniles and subadults, while the remaining individuals belonged to the following seven species: Arctosa leopardus, Pardosa amentata, Pardosa proxima, Pirata piraticus, Piratula latitans, Trochosa robusta and Trochosa ruricola. The reproductive period of some species is altered under the influence of neighbouring hot waters, as revealed by the capture of females with egg sacs and spiderlings, during winter.     

A new genus and species of Conchaspididae (Hemiptera: Coccoidea) from Florida,remarkable in lacking legs

A new genus of Conchaspididae, Asceloconchaspis gen. nov., is described for Asceloconchaspis milleri sp. nov., a new species from Florida, USA. Unlike other conchaspidids, the adult female and second instar of the genus lack legs. The presence of legs is one of the important, distinguishing characters at present separating the Conchaspididae from the Diaspididae. However, the new genus also possesses well-developed antennae and has multilocular disc pores on the abdomen in the adult female; these distinctly conchaspidid characters are never found in the Diaspididae. Asceloconchaspis is closely related to Fagisuga Lindinger, a monotypic genus with primitive characters described from South America on Nothofagus. A key to the four known genera of Conchaspididae is provided, and the morphology and distribution of the Conchaspididae are discussed.     

Molecular and morphological identification of two new African species of Dugesia (Platyhelminthes,Tricladida, Dugesiidae) from Cameroon

The paper describes two new Dugesia species collected from the rivers Messassi and Ntsetsensooh in Cameroon, representing the first planarian flatworms documented from this country. Based on morphological data, the new species Dugesia bijuga Harrath & Sluys, sp. nov. is characterized mainly by the presence of two diaphragms, a barrel-shaped penis that is traversed by numerous ducts of penis glands and is provided with a short nozzle, and the presence of two atrial folds. The other new species, Dugesia pustulata Harrath & Sluys, sp. nov., is characterized mainly by absence of a penis bulb, presence of a large, elongated and weakly muscular seminal vesicle, and by the ventroposterior section of the bursal canal being thrown into distinct folds. The phylogenetic position of the two new species was determined through a molecular phylogenetic tree, based on a mitochondrial and a nuclear gene, including species from the major geographical range of distribution of the genus Dugesia. The phylogenetic tree revealed that the Cameroon lineage does not constitute a monophyletic group with the other Afrotropical species; it also showed that the African continent may house a great diversity of Dugesia species that still remains to be discovered.

Apogon andhrae,a new species of apogonid fish from the Bay of Bengal

Summary

A new species of Apogon from Indo-West Pacific is described. A. andhrae sp. nov. can be distinguished from the closely related A. ellioti Day by the absence of the pigment band on the anal fin and of pigment spots on the dorsal side of head, and the presence of a narrow black edge to the caudal fin.     

First record of the genus Atlantistylis Reyss, 1975 (Crustacea: Cumacea) from the North Atlantic,with the description of a new species

A new species of the genus Atlantistylis Reyss, (Diastylidae) is described from the Atlantic Frontier Margin (North‐East Atlantic). This is the first record of the genus Atlantistylis from the North Atlantic. The new species Atlantistylis borealis can be recognized by the presence of spines on the frontal and lateral lobes of the carapace combined with their absence on the pereon and pleon; the first pereopods are very long. The small telson with two small apical acuminate setae and the absence of pleopods in the male are characteristic of the genus.     

A new species of Fabricinuda Fitzhugh, 1990 (Fabriciinae: Sabellidae: Polychaeta) from the Caribbean,with an emendation of the genus

During a survey of the infauna of seagrass meadows in Venezuela, several specimens of an unknown species of Fabriciinae were collected. The species could not be assigned to any genus of the subfamily, although it was most closely allied to Fabricinuda Fitzhugh, 1990. However, the absence of pseudospatulate inferior notochaetae on chaetiger 8 prevented assignment of the specimens to this genus since their presence on chaetigers 3 to 8 is one of its diagnostic apomorphies. In order to decide whether to establish a new genus for the species or to redefine Fabricinuda, a phylogenetic analysis of the subfamily was made on the basis of a pre‐existing character matrix. Twenty‐two anatomical characters were analysed for 59 species including the new one, and from the resulting consensus tree it was clear that the new species must be included within Fabricinuda and consequently an emendation of the genus is provided herein.     

Borneodessus zetteli,new genus and new species,notes on biogeography and a checklist of Dytiscidae from Borneo (Insecta: Coleoptera: Dytiscidae)

A new genus of Dytiscidae, Borneodessus gen. n., is described for Borneodessus zetteli zetteli sp. n. (Sabah, East Malaysia) and Borneodessus zetteli kalimantanensis ssp. n. (East Kalimantan, Indonesia). The new genus belongs to the tribe Bidessini because of the presence of two-segmented parameres of the aedeagus. A modified male clypeus is an apomorphy for Borneodessus zetteli. The species habitually resembles some species of Africodytes Biström, 1988 (Africa), Amarodytes Régimbart, 1900 (South America), and some Clypeodytes Régimbart, 1894 (Old World tropics). However, a sister group relation or closer affinities to any of the genera of Bidessini could not be established. Borneodessus is so far the first genus of Dytiscidae which is endemic to Borneo, but we suggest a certain probability of its occurrence in other Sundaic areas. The species is a rheobiont, being collected from forest streams. We briefly address biogeographical aspects and provide a checklist of Bornean Dytiscidae, indicating the currently known degree of endemism.     

Orb‐web spiders (Araneae: Araneomorphae; Orbiculariae) captured by hunting‐wasps (Hymenoptera: Sphecidae) in an area of Atlantic Forest in south‐eastern Brazil

Members of two hunting‐wasp families, Pompilidae and Sphecidae, are among the major predators of orb‐web spiders. In this study, we collected paralysed spiders from natural nests and trap‐nests provisioned by sphecids in an area of Brazilian Atlantic Forest, and compared these data with the composition of species collected by visual searching during one year. Prey preferences were analysed based on the relative abundance of spider species, their size and web characteristics. We also compiled a list of orb‐weavers captured by four sphecid genera reported in 40 other studies. A large number of prey was obtained from natural nests of Trypoxylon (Trypargilum) albonigrum in Parque Estadual Intervales, especially species of Eustala, Parawixia, and Araneus (Araneidae). Other prey, stored in trap‐nests by T. lactitarse and unidentified hunting‐wasp species, included Nephila (Tetragnathidae), Parawixia, Ocrepeira, Mecynogea, Acacesia (Araneidae), and other spider species that were less abundant. All the species that were heavily preyed upon had a relatively lower abundance in our samples of prey availability. The range of body sizes of spiders captured by Trypoxylon in our study area include the size of some abundant orb‐weavers always absent in their nests. These results indicate that factors other than abundance in the field and the spider's size influence prey selection or susceptibility to attack.
