Two new species of genus Arrenurus Duges, 1833 (Arrenuridae,Hydrachnellae, Acari) from Turkey

The males and females of Arrenurus dileri n. sp. collected from standing waters at the foothills of the Taurus Mountains in southern Turkey and males of Arrenurus ???kl?ensis n. sp. collected from I??kl? Lake, which is located in south-west Turkey, are described here. The morphological features of the species are compared with those of the similar species Arrenurus claviger Konike, 1882 and Arrenurus nodosus (Koenike, 1896).     

A new species of Hydropsyche (Trichoptera: Hydropsychidae) from Utah

Hydropsyche quitchupaha, n. sp. , is described and illustrated based on 3 males collected in Sevier, Emery, and Kane counties, Utah. The upturned posteromesal lobes of tergum X, subapically swollen phallobase, and dorsally depressed phallus apex separate this species from all other members of the Hydropsyche scalaris Group.     

New species of Australopericoma Vaillant (Diptera: Psychodidae) from the Brazilian semiarid region and key to males of the genus

A new species of moth fly, Australopericoma paraibana sp. n., is described from areas of the Brazilian semiarid region, in the states of Paraíba and Bahia, north-eastern Brazil. A key to males of Australopericoma and morphological remarks on Australopericoma caudata (Satchell) are also provided.     

Re‐description of the lycosiformis species group of Anyphops Benoit and description of two new species (Araneae,Selenopidae)

Anyphops Benoit is a heterogeneous genus with 62 known species restricted to the Afrotropical region. It is split into four species groups using the number of ventral spine pairs on tibiae I–II. The lycosiformis species group (?=?B‐B1 species group of Lawrence) is characterized by four ventral pairs of spines and includes Anyphops lycosiformis (Lawrence), A. natalensis (Lawrence) and A. parvulus (Pocock). In this paper, I revise this species group and include here A. mumai Corronca, A. lawrencei (Roewer) and two new species: Anyphops ngome n. sp. and A. lucia n. sp. from South Africa. Drawings of the female and male genitalia and some somatic characters are given, in some cases for the first time. A key for the lycosiformis species group and a map showing the distribution of each species are provided.     

Three new species of Gamasiphis (Acari: Mesostigmata: Ologamasidae) from Brazil,with complementary information about Gamasiphis plenosetosus Karg and a key to the world species of the genus

Gamasiphis Berlese is one of the most diverse genera of Ologamasidae, with 68 described species, corresponding to about 15% of the species of the family. Until now, a single species of this genus was known from Brazil. Gamasiphis salvadori sp. nov., Gamasiphis flechtmanni sp. nov. and Gamasiphis edmilsoni sp. nov. are described based on the morphology of adult females and males collected from litter and soil in Piracicaba, São Paulo State, Brazil. The holotype of Gamasiphis plenosetosus Karg, 1994 was examined, given its close similarity with the latter species, and complementary morphological information about it is provided. A key for the separation of females of the 60 recognizable world species of Gamasiphis is provided.     

Nine new species of Braconidae (Hymenoptera) from the Russian Far East

Nine new species of Braconidae from the Russian Far East are described and illustrated: Tebennotoma spasskensis sp. n., Parahormius bikinus sp. n., Colastes (Colastes) ussuricus sp. n., C. (Shawiana) kurilensis sp. n., C. (S.) bohayicus sp. n., Oncophanes makarkini sp. n., Doryctes slavianka sp. n., Brulleia chankaica sp. n., Cardiochiles turga sp. n. The genera Tebennotoma Enderlein and Brulleia Szépligeti are recorded for the Russian fauna for the first time.     

Atlantic and Mediterranean species of the genus Andaniexis Stebbing (Amphipoda: Stegocephalidae)

The Atlantic and Mediterranean species of the genus Andaniexis Stebbing, 1906 (Amphipoda: Stegocephalidae) are reviewed, and three new species are described. The species Andaniexis abyssi (Boeck, 1871) which previously was considered a widely distributed species (from Baffin Bay to both Spitzbergen and the Skagerrak), is here divided into three species: Andaniexis abyssi s.str., Andaniexis gracilis n.sp. and Andaniexis lupus n.sp. These species, together with Andaniexis mimonectes Ruffo, 1975, all have allopatric distributions. This is especially evident in northern Norway, where A. abyssi has its northernmost limit: A. abyssi is found in Solbergfjorden (69°10′N), while Andaniexis lupus is found in the adjacent fjord Malangen (69°30′N, the southern limit of this species along the Norwegian coast). Andaniexis eilae n.sp. is described from Iceland. This species is not closely related to the other North Atlantic species of the same genus.     

First collections of water mites (Acari: Hydrachnidia) from Honduras: descriptions of six new species

First collections of water mites (Acari: Hydrachnidia) from Honduras indicate a rich fauna. Nineteen species from just three sites yielded six species new to science. New species described and discussed are: Hydrodroma moralesi n. sp., Flabellifrontipoda triscutata n. sp., Monatractides angelae n. sp., Pseudotorrenticola espinasseae n. sp., Atractides jenniferae n. sp. and Recifella cusucoensis n. sp.     

New species of Pauropodidae (Myriapoda: Pauropoda) from Nanjing,China

Six new species in the family Pauropodidae are described from China: Allopauropus disphaeroides sp. n., A. crassescens sp. n., A. apicalis sp. n., A. nanjingensis sp. n., Pauropus dorsappendix sp. n., and Stylopauropus zijinensis sp. n.     

New species of Doliodrilus and other Limnodriloidinae (Oligochaeta,Tubificidae) from Hainan and other parts of the north-west Pacific Ocean

Thirteen species of Limnodriloidinae (Tubificidae) are recorded from marine and brackish-water habitats of Hainan Island, southern China, including 11 species of Doliodrilus and two species belonging to Limnodriloides. Eight species are new to science: D. bisaccus sp. n. (types from Japan), D. longidentatus sp. n. (types from Hong Kong), D. ciliatus sp. n., D. adiacens sp. n., D. fibrisaccus sp. n. (also from Fiji), D. brachyductus sp. n., D. bidolium sp. n. and D. chinensis sp. n. In addition, material of D. puertoricensis Erséus and Milligan, 1988, from New Caledonia, is briefly described. This study shows that Doliodrilus is unexpectedly species-rich in Asian seas, in particular, around Hainan. Including an unnamed species from this island, the known members of this genus increase from three to 12.     

First record of a freshwater Pisionidae (Polychaeta): description of a new species from Panama with a key to the species of Pisione

A new species of Pisione Grube, 1857, Pisione garciavaldecasasi n. sp. (Polychaeta: Pisionidae) is described from several small rivers in Cobia Is., Pacific, off Panama. This is the first report of a freshwater Pisionidae and it is one of very few known species of true freshwater polychaetes. The species is characterized by large size, by dorsal cirri of setiger 2 and ventral cirri of setiger 1 only slightly elongated, by non-successive male copulatory organs, and by parapodia each with one compound seta with long blade and three others with short blades.     

New species of Isometopinae (Hemiptera: Miridae) from the Ivory Coast and Yemen

Myiomma cobbeni n. sp. and Paloniella nodifrons n. sp. are described from the Ivory Coast. Additionally, M. maculata n. sp., Isometopus yemenensis n. sp. and I. quadrivittatus n. sp. are described from the Republic of Yemen. The new species from Yemen represent the first records of Myiomma Puton and the subgenus Jehania Distant of Isometopus Fieber from the Middle East.     

Three new species of Pseudohaliotrema Yamaguti, 1953 (Monogenea: Ancyrocephalidae) from Siganus species (Siganidae) and the description of a mechanism for cross-insemination

Three new species of Pseudohaliotrema Yamaguti, 1953 were collected from two Siganus species caught off Singapore. They are Pseudohaliotrema virgata n. sp. and P. molnari n. sp. from Siganus virgatus and P. falcata n. sp. from S. guttatus. They differ in the shape and size of both the body and haptoral sclerites and in the morphology of the male organ (modified copulatory organ). Pseudohaliotrema species from siganids are characterized by having a large prominent vaginal pouch, an eversible spermatophore transfer tube associated with the vaginal pouch, ovoid spermatophores (in mature worms), a male organ adapted for spermatophore formation, a large prostatic reservoir, and a testis and ovary arranged side by side. Pseudohaliotrema plectocirra Paperna, 1972 is re-assigned as Tetrancistrum plectocirra (Paperna, 1972) n. comb. Pseudohaliotrema species from non-siganid fish do not possess these characteristics and belong elsewhere. The generic diagnosis of Pseudohaliotrema is amended. Pseudohaliotrema species use a spermatophore for sperm transfer, which is documented in detail for P. virgata n. sp. The same reproductive strategy is used by P. molnari n. sp. and P. falcata n. sp., as indicated by the presence of spermatophores on the spermatophore transfer tube and inside the vaginal pouch. The presence of individuals exchanging spermatophores indicates that P. sphincteroporus Yamaguti, 1953 and P. sigani Yamaguti, 1953 also employ the same mechanism. The spermatophore, assembled in the sclerotized male organ and stored in the spermatophore chamber, is retrieved by the eversible spermatophore transfer tube (housed within the vaginal pouch) and drawn into the vaginal pouch as the spermatophore transfer tube invaginates. Within the vaginal pouch, the wall of the spermatophore disintegrates releasing spermatozoa.

The occurrence of a new species of Isocyamus (Crustacea,Amphipoda) from Australian and Japanese Pilot Whales,with a key to species of Isocyamus

Isocyamus deltobranchium n. sp. is described from the short-finned pilot whale, Globicephala macrorhynchus Gray 1946 in Japanese waters, and the long-finned pilot whale, Globicephala melaena (Traill 1809) from Tasmania, Australia. To date only two species of Isocyamus have been described: I. delphini (Geurin-Meneville 1836) Gervais and Beneden, 1859 and I. kogiae Sedlak-Weinstein 1991. The present species differs from I. delphini and I. kogiae in having large triangular accessory gills in the males, and a bilobed maxilla 2. It is similar to I. delphini in ventral spination, and single serrated comb on dactylus of gnathopod 1. Isocyamus deltobranchium n. sp. is the second species of cyamid reported from the long-finned pilot whale and the first from the short-finned pilot whale. The occurrence of I. deltobranchium in the northern and southern hemispheres, and in two different host species, suggests that the ranges of the host species overlap.     

Three new species of the deep-sea genus Neotanais Beddard (Crustacea: Peracarida)

Three new species of the deep-water family Neotanaididae Lang are described. Neotanais minimus n. sp. and N. curvimanus n. sp. were collected from the Gulf of Mexico and are the first species to be described from this region. Neotanais minimus cannot be grouped with other Neotanais species, since it displays characters from all groupings. Neotanais curvimanus has strong affinities to the ‘americanus’ group but can be separated by the short pereonite 6 and by the presence of many setulose setae lateral on the pleonites. Male N. curvimanus can easily be separated from all other species of the genus by the cheliped fixed finger being only half as long as the dactylus and the dactylus being incurved from fixed finger at an angle of about 40°. Neotanais noelietaiti n. sp. was found off south-east Australia and is the first Neotanais species to be described from Australian waters. It also has strong affinities to the ‘americanus’ group but can be distinguished by the complete lack of a midventral keel and by the uropodal exopod being as long as the endopod article 1.     

Diversity and distribution of marine Gastrotricha along the northern beaches of the state of São Paulo (Brazil), with description of a new species of Macrodasys (Macrodasyida,Macrodasyidae)

Forty-three putative species were found in this first-ever survey of the marine gastrotrich fauna of Brazil. Samples from 23 locations and 37 sites along the northern coasts of the state of São Paulo yielded 21 species of Macrodasyida (12 genera and five families) and 22 species of Chaetonotida (seven genera and two families). Based on morphology, 26 species appear to be taxa not previously described and thus far endemic to Brazil, 13 are known species, while one in each of the genera Diplodasys, Paradasys and Tetranchyroderma remains undetermined. The overall high diversity contrasts with the generally low number of species from single locations, averaging 4.3 (SD 3.5) spp. per location; very few species were found in sites characterized by very fine sand sediment loaded with detritus and by high water turbidity (e.g. 1 sp. in praia da Fazenda), whereas a well-diversified gastrotrich community was found in localities characterized by medium or fine sand with little detritus and clear water (e.g. 14 spp. in praia de Castelhanos). The macrodasyidans, Paraturbanella sp. 1, Pseudostomella sp. 1 and Tetranchyroderma sp. 1, and the chaetonotidan Heteroxenotrichula sp. 1 were the most common species, often sympatric and particularly frequent and abundant along the continental shoreline (recorded in 50–65% of these localities); on the other hand, Macrodasys fornerise n. sp., Ptychostomella sp. 1, Tetranchyroderma sp. 3 and Thaumastoderma sp. 2, while occurring sometimes in very high numbers, exhibited a much narrower range, being encountered only once or twice during the survey. The main morphometric traits are described of the 13 species considered to be cosmopolitan or with at least an amphi-Atlantic distribution, including Chaetonotus apechochaetus and Halichaetonotus marivagus, reported here for the first time from the Americas; of the 26 species thus far endemic to Brazil, Macrodasys fornerise n. sp., which is characterized by a noticeable 145?µm-long frontal organ, is also described and figured.
