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.     

A key to Neodohrniphora (Diptera: Phoridae), parasites of leaf-cutter ants (Hymenoptera: Formicidae)

A key to the females of Neodohrniphora Malloch is provided. A species referred to as Apocephalus sp. by Eibl-Eibesfeldt and Eibl-Eibesfeldt (1967) is assigned to N. attae sp. nov., and to a newly designated subgenus Eibesfeldtphora for the N. curvinervis (Malloch) group of species. Neodohrniphora frontalis (Curran) is confirmed as a synonym of N. (E). curvinervis. The paratype of N. (N.) acromyrmecis Borgmeier differs from the lectotype, and is reassigned to N. (N.) similis Prado. A new subgenus, Wallerphora, is designated for N. (W.) mexicanae sp. nov. from Mexico.     

Observations on the “tenuis group” (Eutardigrada,Macrobiotidae) and description of a new Macrobiotus species

A new species of the tardigrade genus Macrobiotus is described. The species, designated M. ciprianoi n. sp., was isolated from a mixture of Provence broom leaf litter and mosses, and from rock mosses collected in the Sierra de Guadarrama, Madrid (Spain). Given that Macrobiotus ciprianoi n. sp. shares several characters to members of the “tenuis group”, we assessed the taxonomic homogeneity of the group. The new species differs from those of the “tenuis group” according to a unique set of characters related with claw shape, features of the buccal‐pharyngeal apparatus, and egg morphology. Our analysis of holotypes and/or paratypes of “tenuis group” species and other Macrobiotus species with similar characters (M. bondavallii and M. caelicola) reflects the heterogeneity of this group of species as currently described.     

A new species of Halolaelapidae (Acari: Mesostigmata: Rhodacaroidea) from beach wrack in Yaquina Bay,Oregon, USA,with comments on opisthonotal plasticity and cribral development in the family

Decomposing beach wrack in a backwater of Yaquina Bay, Oregon, was found to contain nymphs and adults of a previously undescribed species of the mite genus Halolaelaps (Halolaelapidae). Significant variation was noted among available specimens in the number of opisthonotal shield setae, a feature that has long been considered to be of critical importance in identifying celticus group species. The presence of a well-formed posterodorsal cribrum in this and related celticus group species prompted an examination of cribral development in the Halolaelapidae as a whole and revealed that posterodorsal cribral elements occur in various configurations in three of the four presently recognized halolaelapid genera. A narrow, transversely oriented configuration appears to be unique to members of the celticus species group.     

Diversity and biogeography of the little known deep-sea barnacles of the genus Waikalasma Buckeridge, 1983 (Balanomorpha: Chionelasmatoidea) in the Southwest Pacific,with description of a new species

Due to the extreme scarcity of specimens, little is known about the biodiversity and biogeography of the barnacles of the genus Waikalasma Buckeridge, 1983 (Thoracica: Waikalasmatidae Ross and Newman, 2001), which inhabit the deep sea of the Southwest Pacific. Previous studies reported only a single living species, W. boucheti Buckeridge, 1996, from Vanuatu. In the present study, the collections by French deep-sea expeditions off New Caledonia (NORFOLK 1 & 2, EBISCO, SMIB 2, SMIB 4, SMIB 8, BIOCAL, MUSORSTOM 6, MUSORSTOM 4, MUSORSTOM 5, BATHUS 2), the Solomon Islands (SALOMON 1), Vanuatu (BOA1) and Papua New Guinea (BIOPAPUA) yielded specimens of Waikalasma species from 500 to 800 m depth. From molecular (DNA barcode region cytochrome c oxidase subunit I (COI) and 12S gene) and morphological analysis, a new species Waikalasma dianajonesae sp. nov., and W. boucheti were identified. From molecular phylogenetic analysis, sequence divergence in the DNA barcode region between W. dianajonesae sp nov. and W. boucheti reached > 10%. Waikalasma dianajonesae sp. nov. differs from W. boucheti in the number and size of imbricating plates on the shell and the shape of the tergum. Waikalasma dianajonesae sp. nov. and W. boucheti exhibit sympatric biogeographical distributions in the Southwest Pacific. Waikalasma dianajonesae was found in the waters of Papua New Guinea and Solomon Island, whilst W. boucheti was collected from Papua New Guinea, Vanuatu and New Caledonia waters.

The Stegana shirozui species group (Diptera,Drosophilidae) from East Asia

One subgroup of the Stegana (Steganina) coleoptrata species group is elevated as a species group (i.e., the shirozui species group), so as to include the three known species, S. ctenaria Nishiharu, S. (S.) masanoritodai Okada and Sidorenko and S. (S.) shirozui Okada, as well nine new species reported from China and Japan: S. (S.) jiajinshanensis, S. (S.) jianfenglingensis, S. (S.) maoershanensis, S. (S.) multidentata, S. (S.) qinlingensis, S. (S.) saigusai, S. (S.) shennongi, S. (S.) wuyishanensis and S. (S.) xanthosticta spp. nov. A key to all the species of this group is provided.     

New Polypheretima and Pithemera (Oligochaeta: Megascolecidae) species from the Mt. Malindang Range,Mindanao Island,Philippines

We describe four new pheretimoid earthworm species, one in Polypheretima and three in Pithemera, from Mt. Malindang, Misamis Occidental Province, Mindanao Island, Philippines, and provide diagrams of external morphology and internal anatomy. Polypheretima mindanaoensis sp. nov. belongs to the Po. elongata species group, characterised by having genital markings on xix and successive segments and pairs of spermathecal batteries in vi and/or vii. It differs from the other members of the Po. elongata species group in having no copulatory bursae. This species shows individual variation in the number of spermathecae in each battery. Individuals that lack spermathecae are presumed to reproduce parthenogenetically. Pithemera malindangensis sp. nov. and Pi. duminagati sp. nov. belong to the Pi. bicincta species group, characterised by having the first spermathecal pores in 4/5. These two species differ in size and in the distance between male pores. Pithemera donvictorianoi sp. nov. belongs to the Pi. pacifica species group, characterised by having the first spermathecal pores in 5/6. This is the only member of this species group so far reported from the Philippines, and this is the only Philippine Pithemera species whose clitellum covers two rather than two and a half segments. Current studies show that worldwide, the Philippines has the highest diversity for Pithemera, with 13 species, followed by Papua New Guinea and the Pacific Islands, each area with six species. Indonesia has the highest diversity for Polypheretima, with 18 species, followed by Vietnam with 13 species, and then Papua New Guinea and the Philippines, each area with eight species. These findings indicate a high degree of endemicity within these areas, suggesting that many species remain to be detected in the Philippines.

Dhanya,a South-east Asian genus of ozaenine ground beetles

The species of the South-east Asian genus Dhanya are reviewed, and three new species are described: mulu from Sarawak; andrewesi from India; and cylindera from Philippines. Dhanya bioculata is designated as the type-species and a lectotype is designated for this species. The variety pallida is synonymized with its species seminigra. The species cavicola Moore is transferred from Pseudozaena to Itamus. Keys to the genera of South-east Asian Ozaenini and to the species of Dhanya are provided. Morphological details of Dhanya are illustrated with scanning electron micrographs and drawings, and include information on the structure of the prothoracic pits, elytral flanges, and on microsculpture. A cladistic analysis of the species is included and the relationship of the genus to its sister group, Eustra, and to the other genera of Ozaenini is discussed. Specimens of Dhanya are found under bark of fallen logs and in rotting tree stumps in lowland and upland tropical rain forest; an association with ants or termites is suggested for at least one species.     

Northeastern Atlantic and Mediterranean hermit crabs (Crustacea: Anomura: Paguroidea: Paguridae). I. The genus Pagurus Fabricius, 1775

A reappraisal of adult taxonomy of N.E. Atlantic and Mediterranean hermit crabs upholds the divisions A & B suggested for the species by MacDonal et al. (1957) from their studies of larval features. The nomenclature of three species is discussed. Pagurus variabilis (A. Milne Edwards and Bouvier, 1892) is relegated to the synonomy of P. alatus Fabricius, 1775 and P. excavatus (Herbst, 1791) is reinstated for Mediterranean and southern N. E. Atlantic material. A provisional check list is given of Paguroidean species occurring within the sea area 30°N–80°N:30°W–30°E and the Mediterranean Sea. An illustrated identification key is provided to the Pagurus species within these regions.     

Red Sea Phyllidiidae (Mollusca,Nudibranchia), with descriptions of new species

All the known Red Sea nudibranchs of the family Phyllidiidae are described and their taxonomic positions discussed. The genus Fryeria Gray, 1853, is regarded as a junior subjective synonym of Phyllidia Cuvier, 1797, and Reyfria gen. nov. is introduced to describe those species differing from Phyllidia primarily in the position of the anus. Of 12 species described here from the Red Sea, four are new to science. Phyllidia arabica Ehrenberg, 1831, is distinguished from Phyllidia varicosa Lamarck, 1801, and Phyllidia sp. is described as the third species confused with this group. A subspecies of P. ocellata Cuvier, 1804, is described and illustrated, as are three new species: P. melanocera, P. monacha and P. multifaria.     

The catfish genus Akysis Bleeker (Teleostei: Akysidae) in Indochina,with descriptions of six new species

Catfishes of the genus Akysis Bleeker occurring in the Mekong basin south of the Chinese border, in the Mae Nam Chao Phraya basin, in the Malay Peninsula and the basins in between are reviewed. Nine species are recognised, six of which are new: A. alfredi, A. ephippifer, A. recavus, A. similis, A. subtilis and A. varius. Two groups of species were identified: one group (the pseudobagarius group) is characterised by its members possessing a relatively elongate body, conspicuously subterminal mouths with the upper jaw strongly overhanging the lower, relatively large posterior and anterior nostrils closely located to each other and separated only by the base of the nasal barbel, and strongly-forked caudal fins. The second group (the variegatus group) is characterised by its members possessing a relatively deep body, the margins of the upper and lower jaws uniform, relatively small posterior and anterior nostrils located further apart with a distance between the base of the nasal barbel and anterior nostril, and emarginate or truncate caudal fins. The pseudobagarius group contains the following species: A. alfredi, A. Baramensis, A. fuscus, A. leucorhynchus, A. macronema, A. pseudobagarius, A. sinensis, A. similis, and A. subtilis. All other species of Akysis belong to the variegatus group. A key to the Indochinese Akysis is provided.     

The pygmaeus-group of Euops Schoenherr (Coleoptera,Curculionoidea, Attelabidae), weevils associated with Nothofagus in New Guinea

A new species group of Euops Schoenherr from the highlands of New Guinea is described and referred to as the ‘pygmaeus-group’. It is comprised of 14 species which, except for E. singularis VOSS, are described as new: E. anggiensis sp. n., E. bicolor sp. n., E. convexus sp. n., E. fraterculus sp. n., E. ibelensis sp. n., E. kurulu sp. n., E. nothofagi sp. n., E. parvus sp. n., E. paraconvexus sp. n., E. platyrostris sp. n., E. porulosus sp. n., E. pygmaeus sp. n., and E. sedlaceki sp. n.. Most of the species are of relatively small body size. They form a monophyletic group characterized by the synapomorphic loss of the ventral suture between the galea and palpifer of the maxilla. Two other groups are recognized, the eucalypti-group and the quadrifasciculatus-group. They are believed to be closely related to the pygmaeus-group and all three species groups together are referred to as the ‘pygmaeus-complex’. A cladistic analysis of the pygmaeus-group is performed. All species with host records are reported to feed on the fresh leaf flush of Nothofagus. This is the first record of a group of leaf-chewing arthropods restricted to the subgenus Brassospora of Nothofagus.     

Two new Mastigodiaptomus (Copepoda,Diaptomidae) from southeastern Mexico,with a key for the identification of the known species of the genus

Two new species of the freshwater planktonic copepod genusMastigodiaptomus—M. maya and M. reidae—are described from material collected in southeastern Mexico. This neotropical genus is known to be distributed mainly in the southern part of the United States, Mexico and Central America, and now embraces eight species. Of these, six occur in Mexico. Both new species seem to be closely related to M. texensis and M. albuquerquensis. It is probable that this group of Mexican species represents a northwards radiation from the Proto-Antilles-Central America region into the continent, eventually reaching North America. A key for the identification of the known species of the genus is provided.     

The jumping plant-lice (Hemiptera,Psylloidea) associated with Schinus (Anacardiaceae): systematics,biogeography and host plant relationships

The gall-forming psylloid fauna associated with the temperate Neotropical plant genus Schinus (Anacardiaceae) is revised, and keys are provided for adults, larvae and galls. Fourteen species are recognized in the genus Calophya (Calophyidae), 10 of which are described as new; C. gallifex and C. schini are reinstated from former synonymy with C. rubra. An additional closely related new species, C. clavuligera sp. n., is described from Lithrea spp. In the genus Tainarys (Psyllidae, Rhinocolinae), six species are recognized and, for five of these, Schinus species are confirmed hosts. Two of them are described as new and one is recombined from Leurolophus. A new Leurolophus species is described from Lithrea molleoides. Based on a cladistic analysis Pelmatobrachia, Microceropsylla and Neocalophya are synonymized with Calophya, producing five new and one revised species combinations as well as one nomen nov. A list of the 59 currently recognized species is provided with information on synonymy, distribution and host plants. The cladistic analyses suggest that the Schinus inhabiting calophyids form two monophyletic groups, the C. rubra and C. hermicitae groups, respectively. A discriminant analysis of 15 variables for both males and females provides morphometric characters for separating the morphologically very homogenous adults of the C. rubra group. The phylogenetic relationships of the Rhinocolinae are re-evaluated, and the genera Tainarys and Leurolophus are redefined. Notophyllura is transferred from the Euphyllurinae to the Rhinocolinae. Tainarys forms the sister group of Leurolophus + Notophyllura. Based on mapped distributions four areas of endemism (distribution) are defined: A (Eastern temperate South America), B (Central and Southern Chile, including adjacent parts of Argentina), C (Central Argentina) and D (Peru, Far Northern Chile, and Eastern Bolivia). Cladistic biogeographical analyses with TAS, COMPONENT and an algorithm by Enghoff yielded the general area cladogram (A +(C +(B +D))); the one calculated with BPA differed in the position of D: (D +(A +(B +C))). The reconstruction of vicariant events using a protocol by Hovenkamp, corroborates the former general area cladogram, which is compared to competing hypotheses. The history of dispersal and vicariance events is reconstructed with the programme DIVA. Evidence for cospeciation of Schinus with its associated psylloids is evaluated with COMPONENT and TREE MAP. The likelihood for cospeciation is high in the Calophya hermicitae group, but low in the Calophya rubra group and in Tainarys. The gall shape depends partly from the psylloid, partly from the Schinus phylogeny.     

A new subgenus of the genus Colastes Haliday (Hymenoptera: Braconidae: Exothecinae) for species reared from bracket fungi,with description of two new species from Europe

A new Holarctic subgenus (Fungivenator subgen. nov.) of the genus Colastes Haliday, 1833 (Hymenoptera: Braconidae: Exothecinae) is proposed for a group of species that, as far as is known, has its larvae living on hosts in bracket fungi. The type species (Colastes sandei sp. nov. from Netherlands, Germany and England) and a second species (C. fritzeni sp. nov.) from Finland are described and illustrated. A key to the five known species is included.     

Recent species of the Family Candonidae (Ostracoda,Crustacea) from the ancient Lake Biwa,Central Japan

Sampling of Lake Biwa between November 1997 and February 2007 has revealed a diverse Candonidae fauna consisting of 18 species. Eleven are previously undescribed species, belonging to the genera Fabaeformiscandona (nine species), Pseudocandona (one species) and Cypria (one species), and 10 of these are potentially endemic to the lake. In total there are 12 Fabaeformiscandona species in the lake belonging to two sub‐groups based on the number of setae on the mandible palp, the fabaeformis‐group (10 species) and the acuminata‐group (two species). Including the new Fabaeformiscandona species described herein, Lake Biwa is home to 19% of the approximately 62 described living species of this genus known globally. Although, the new Fabaeformiscandona species are potentially endemic, they do not show a microevolutionary pattern similar to that suggested for the Tanganyikan Cyprideis species flock.     

Morphological variation of Eucyclops elegans (Herrick, 1884) (Copepoda: Cyclopoida) in the Americas and comments on records of Eucyclops conrowae Reid, 1992

Based on an examination of material from different areas of the American continent, we evaluate the morphological variations of Eucyclops elegans (Herrick, 1884) with an emphasis on characters used in the current taxonomy of the genus. Eucyclops elegans is clearly a member of the serrulatus group. Differences in both female and male specimens from North America and South America and the lack of records in southern Mexico and Central America suggest that it is possible that this nominal species contains at least two taxa. Characters such as the ornamentation of the antennal basis and coxa of P4 are described for the tropical species E. conrowae Reid, 1992. This species is clearly not a member of the serrulatus group and differences with respect to the type specimens indicate that records of E. conrowae in Mexico do not correspond to this taxon and should be reassigned to other species.     

Altitudinal patterns of abundances and parasitism in frugivorous drosophilids in west Java,Indonesia

Abundances and parasitism rates of frugivorous drosophilid flies were studied in three localities at altitudes of 250–1350 m in and near Bogor, Indonesia. The drosophilid and parasitoid species were classified into four groups: low-altitude species, high-altitude species, species abundant at a mid-altitude location and species occurring rather evenly from low to high locations. The ananassae and immigrans species groups were major drosophilids collected. All species of the ananassae species group were more abundant at lower altitudes, and the parasitism rate in this species group decreased with increasing altitude. Thus, the host abundance seems to affect the parasitism rate. On the other hand, the rate of parasitism in the immigrans species group showed no apparent relation with altitude or density, possibly due to the fact that species of this species group varied in altitudinal distribution. It is also suggested that the diversity of drosophilid species affects the composition of parasitoid species.
