The species of the parasitic bee genus Osirinus (Hymenoptera,Apidae)

The species in the genus Osirinus Roig-Alsina are revised. Seven species are recognized, including O. ruficrus, new species, from south-eastern Brazil and O. tarsalis, new species, from western Brazil and Peru. Osiris parvicollis Ducke and O. santiagoi Almeida are transferred for the first time to Osirinus. An identification key based mainly on females is provided.     

Revision of the Trogidae of South America (Coleoptera: Scarabaeoidea)

The South American Trogidae are revised. Three genera, Trox Fabricius, Omorgus Erichson (with two subgenera, Omorgus and Haroldomorgus Scholtz), and Polynoncus Burmeister, and 47 species are recorded from the continent and its islands. Trox is represented by the ubiquitous introduced species T. scaber (L.), Omorgus is represented by 13 species and Polynoncus by 33 species. Five new species are described and all others are re-described. A key to all taxa is provided. Adults of all species and their male genitalia are illustrated and their distributions mapped. Observations are presented on phylogeny, zoogeography and biology. The new species are O. capillaceus, O. indigenus, O. nocheles, P. erugatus and P. gibberosus. Four new synonymies are proposed (synonyms listed first): O. triestinae Pittino = P. suberosus (Fabricius); P. furcifer Pittino = P. bifurcatus (Vaurie); P. parafurcatus occidentalis Pittino and P. furcillifer Pittino = P. parafurcatus Pittino. Omorgus badeni (Harold) is reinstated as a valid species. Lectotypes are designated for O. batesi (Harold) and O. badeni (Harold).     

Two new taxa from the Lesser Sundas in the genus Onthophagus (Coleoptera: Scarabaeidae: Scarabaeinae)

Two new Indonesian taxa are proposed in Onthophagus Latreille, 1802, illustrating the composite faunal spectrum of the Lesser Sundas (Indonesia): O. montishannoniae, a new species from Flores, and O. accedens nusatenggaricus, a new subspecies from Lombok and Flores. O. accedens Lansberge, 1883 is, with O. dux Sharp, 1875, placed in what is here defined as the dux subgroup within the subgenus Parascatonomus Paulian, 1932. The three included species‐group taxa are keyed, their status is discussed, and new records are given. The position of O. montishannoniae seems taxonomically and geographically isolated: this species has no known close relatives in the region, neither in the Lesser Sundas, nor anywhere else in Wallacea.     

Species of Oswaldella Stechow, 1919 (Cnidaria: Hydrozoa: Kirchenpaueriidae) from US Antarctic expeditions,with the description of three new species

Seventeen species of the genus Oswaldella Stechow have been studied, three of which are new to science (Oswaldella frigida sp. nov., O. medeae sp. nov. and O. monomammillata sp. nov.). The material studied was collected by several US Antarctic expeditions. Each species is described and figured, the systematic position amongst allied species is discussed and available data concerning autecology and geographical distribution are given. The remaining eight known species of the genus are also considered, regarding synonymy, autecology and geographical distribution. Finally, a general survey of the bathymetrical and biogeographical distribution of the known species of Oswaldella is given.     

Oncodiscus sauridae Yamaguti, 1934 from Saurida undosquamis in Kuwait and a revision of the genus Oncodiscus (Cestoda: Bothriocephalidae)

Oncodiscus sauridae Yamaguti, 1934 is described and figured in detail from specimens collected from Saurida undosquamis (new host) and S. tumbil in the Arabian Gulf and Australian waters, respectively (new geographical localities). O. fimbriatus and O. waltairensis are regarded as synonyms of O. sauridae. O. maharashtrae is regarded as species inquirenda. The diagnosis of the genus Oncodiscus is emended.     

Recent and fossil Lunulitidae (Bryozoa: Cheilostomata) 4. American and Australian species of Otionella

The nominal, free living lunulitiform genus Otionella has been found to include two major groups of species, each one with a distinctive periancestrular pattern of primary zooids. The first group occurs in the Eocene of North America and includes the type species, O. perforata, and several other forms. The second group occurs in the Late Eocene to Recent of Australasia, and may prove to be generically distinct. Intermediate forms, such as O. parvula from the Argentinian Tertiary, are discussed, and a diverse fauna of 10 species from Australia is described. Although some of these species, like O. cupola, O. exigua and O. nitida, have long been known from Australia. it has only recently been recognized that three New Zealand forms, O. squamosa, O. zelandica and O. proberti, also occur in the Tertiary and/or Recent of Victoria, New South Wales, and Western Australia. In addition, four species are considered to be new. These include O. australis, O. auricula and O. minuta, which are probably closely related to one another, and to O. zelandica. The fourth species, O. browni, has a unique periancestrular budding pattern which resembles that of fossil Lunulites more than any form of ‘Australasian Otionella’. Although, in many ways, O. browni could be assigned to Lunulites sensu lato, it is included here in Otionella.     

The Mediterranean species of Malmgreniella Hartman, 1967 (Polychaeta: Polynoidae: Polynoinae), including the description of a new species

The present review is based on material from different localities in the Mediterranean Sea, and where appropriate, on type material; it comprises all Malmgreniella species known to occur in this area: i.e. Malmgreniella andreapolis (McIntosh, 1874), M. castanea (McIntosh, 1876), M. darbouxi Pettibone, 1993, M. lilianae Pettibone, 1993, M. ljungmani (Malmgren, 1867), M. lunulata (Delle Chiaje, 1830), M. polypapillata sp. nov. Two species are new for the Mediterranean: M. lilianae, previously only known from the southwest Atlantic, represents a new record, and M. polypapillata is a new species, occurring not only in the Mediterranean, but probably also in the northeast Atlantic. The seven Malmgreniella species listed above are described and figured, and an identification key is provided. Furthermore, the subfamily affiliation of the genus Malmgreniella Hartman, 1967 and the validity of Malmgrenia McIntosh, 1874 are discussed.     

New species of Orasema (Hymenoptera: Eucharitidae) from Central and South America

ABSTRACT

Six new species of Orasema are described. Four species are placed into a newly recognised lasallei species group: Orasema lasallei sp. nov. (Costa Rica, Honduras, Mexico, Nicaragua), O. janzeni sp. nov. (Costa Rica), O. peckorum sp. nov. (Brazil) and O. vasquezi sp. nov. (Colombia). One species is placed in the wayqecha group, Orasema masneri sp. nov. (Ecuador). One other species is currently unplaced to species group, O. longinoi sp. nov. (Costa Rica). Orasema lasallei was taken from a nest of Pheidole vorax (Fabr.) and an undescribed species near O. longinoi from a nest of Pheidole dossena Wilson (Myrmicinae). The morphology of the digitate labrum is discussed with respect to other Eucharitidae.     

Ooencyrtus marcelloi sp. nov. (Hymenoptera: Encyrtidae), an egg parasitoid of Heliconiini (Lepidoptera: Nymphalidae: Heliconiinae) on passion vines (Malpighiales: Passifloraceae) in Central America

A new species belonging to the genus Ooencyrtus Ashmead is described. Ooencyrtus marcelloi sp. nov. has been reared from eggs of Heliconiini (Lepidoptera: Nymphalidae, Heliconiinae) collected in Panama on Passiflora spp. The new species is compared with its closest Ooencyrtus species, i.e. O. caligo Noyes, O. neustriae Mercet, O. flavipes (Timberlake), O. camerounensis (Risbec), O. endymion Huang and Noyes and Ooencyrtus sp. “undet. C.” (from India). This represents the second record of Ooencyrtus from Heliconinae and the first record of this genus from Panama.     

A new genus with three new species of copepods from the family Diaixidae (Crustacea: Calanoida), and a redefinition of the family

Plankton samples taken in the Gulf of Carpentaria, Australia, yielded material of a new genus containing 3 new species: Anawekia spinosa gen. nov. et sp. nov., A. robusta sp. nov. and A. bilobata sp. nov., which are described herein. The family Diaixidae now contains 12 described species in 2 genera, 9 being in the genus Diaixis. It is noted that 3 of the Diaixis species (including the type species) share some features which are not shared with the remaining 6 species, and that these latter species should probably be placed into a third genus. An amplified redefinition of the family is given.     

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.     

A new species of marine nemertean from Anglesey,North Wales,with a discussion of the genus Paroerstedia Friedrich, 1955

A new species of marine nemertean, Paroerstedia nigrimaculata sp. nov., is described and illustrated from a single specimen found among Corallina in a lower shore rock pool at Rhosneigr, Anglesey, North Wales. No Paroerstedia species has been recorded previously from the British Isles. The systematics of the genus and its contained species are discussed.     

Water mites of the family Hygrobatidae Koch from southern Africa (Acari: Hydrachnidia)

New records are given of the water mite family Hygrobatidae (without the genus Atractides) from southern Africa (South Africa, Botswana, Namibia). In addition to one new subgenus of the genus Hygrobates, namely Inflatibates, four new species are described, namely Hygrobates draconicus, H. laceratoides, H. okavangoensis, and H. inflatipes as well as one new subspecies, namely Hygrobates spathuliferus cederberg. The following synonyms are established: the subgenus Capobates Thor with Hygrobates Koch, Hygrobates sanguineus transvaalensis K. O. Viets with Hygrobates spathuliferus (Lundblad), and Ambiguobates permixtus agnewi K. O. Viets with Ambiguobates permixtus K. Viets. The male of Australiobates pilosus (K. Viets) is described for the first time. The synonymization of Diversibates with Australiobates can now be confirmed. Finally, keys are given for the known genera of southern Africa, as well as for all known species of the genus Hygrobates from southern Africa.     

Minute but constant morphological differences within members of Stenothoidae: the Stenothoe gallensis group with four new members,keys to Stenothoe worldwide,a new species of Parametopa and Sudanea n. gen. (Crustacea: Amphipoda)

The hitherto-known species of Stenothoe are grouped by their distribution. A key for Mediterranean–Atlantic species is given. To the so-called Stenothoe gallensis group (until now, four species), four others are added: S. andamanensis, S. clavetta, S. himyara and S. senegalensis, all new to science. Knowledge of Stenothoe aucklandica, frecanda, macrophthalma, valida and verrucosa is amended. The studied material also yields both a new species of Parametopa (P. gorea n. sp.) and a new genus (Sudanea n. gen.) with S. inopinata n. sp.

North Pacific species of the amphipod (Crustacea) family Stegocephalidae,with description of one new species and redescription of another

The genera and species of the family Stegocephalidae Dana, 1852 (Crustacea: Amphipoda) of the North Pacific, including the Bering Sea, are surveyed, and a key to the species is presented. One new species, Stegocephalus beringi n. sp., is described, and Stegocephalopsis ampulla (Phipps, 1774) is redescribed; S. vegae Oldevig, 1959 is synonymized with S. ampulla. Comments are given on the morphology of three additional species.     

A new deep-water calanoid copepod and the phylogeny of the genus Nullosetigera nom. nov. in the Nullosetigeridae nom. nov. (pro Phyllopus: Phyllopodidae) from Japanese waters

Nullosetigeridae nom. nov. is proposed for Phyllopodidae Brodsky, 1950, nom. nud., and Nullosetigera nom. nov. is introduced for Phyllopus Brady, 1883, non Rafinesque, 1815. A new species, Nullosetigera auctiseta, is described from Japanese waters. Nullosetigera mutica comb. nov. (Sars, 1907) and N. mutata comb. nov. (Tanaka, 1964) are redescribed. Phylogenetic analysis implies that two groups, N. auctiseta–N. mutica group and N. mutata–N. impar–N. bidentata–N. helgae group, exist within the genus Nullosetigera and that the new species first diverges with N. mutica. The relatively advanced species, N. impar, N. bidentata, and N. helgae are the most widespread, and are vertically distributed from the epipelagic to the bathypelagic layers.     

New species and records of Flabellifera from the Indian Ocean (Crustacea: Peracarida: Isopoda)

In this study of flabelliferan Isopoda from the Indian Ocean, 19 species are described as new, in 11 genera and two families: family Cirolanidae, Baharilana koloura, B. lira, Cirolana aldabrensis, C. mimulus, C. somalia, C. undata, Eurydice paxilli, and Metacirolana chemola; family Sphaeromatidae, Cassidinidea clarkae, Cymodoce fuscina, C. lirella, Dynamenella alveolata, D. remex, Heterodina (new genus), H. mccaini, Oxinasphaera brucei, O. furcata, O. tetrodon, Paracilicaea stauros, and Sphaeromopsis sulcifera. Diagnoses of the genera and species are provided, and keys to the Indian Ocean species of most of the genera are provided. The material comes primarily from Aldabra Atoll, the granitic Seychelles islands, Zanzibar Island, and Phuket in Thailand. A few miscellaneous samples from the South African Museum collections, and from the International Indian Ocean Expedition carried out in the mid‐1960s are included.     

Revision of the spider subfamily Gnaphosinae in Israel (Araneae: Gnaphosidae)

Gnaphosid spiders of 6 genera in Israel are revised presenting a relative richness in species and updated information on the Mediterranean spider fauna. Many inhabit the stony deserts of the south or are psammophiles that were detected by pitfall trapping. Minosia, Minosiella and Gnaphosa have never before been reported from Israel. Minosia simeonica sp. n. and the unknown males of M. spinosissima and Minosiella pharia are described. Gnaphosa barroisi is reinstated as a separate species. Berlandina jovia Denis, 1947 is newly synonymized with B. venatrix Dalmas, 1921, while the following B. chopardi Denis, 1955, B. paludani Denis, 1958, B. afghana Denis, 1958 and its subspecies B. a. spinitarsis Denis, 1958, and B. macrostigma Denis, 1966 are new synonyms of B. plumalis (O. P.-Cambridge, 1872) one of the most widely distributed gnaphosids in the Old World. The matching female of Nomisia excerpta and the matching of N. palaestina, each proving a separate species, have been identified, and N. negebensis sp. n. is described. Nomisia marginata (O. P.-Cambridge, 1874) and N. mauretanica Dalmas, 1921 are new synonyms of N. ausserei (L. Koch, 1872), N. verneaui (Simon, 1889) = N. excerpta (O. P.-Cambridge, 1872), and N. soror Dalmas, 1921 = N. palaestina (O. P.-Cambridge, 1872). In Pterotricha, the largest genus of Gnaphosinae in the Middle East, P. levantina sp. n., P. parasyriaca sp. n., P. engediensis and the unknown female of P. dalmasi are described, and the following new synonyms are recognized: P. aegyptiaca Dalmas, 1921 and P. isiaca Dalmas, 1921 = P. conspersa (O. P.-Cambridge, 1872); P. fanatica Dalmas, 1921 = P. lesserti Dalmas, 1921; P. peregrina Denis, 1948 = P. chazaliae (Simon, 1985); P. lentiginosioides Nosek, 1905 = P. kochii (O. P.-Cambridge, 1872). Illustrations of diagnostic characters, records of distribution and pertaining literature are provided for each species.
