A new genus of quill mites of the family Syringophilidae (Acari: Cheyletoidea) associated with mousebirds (Aves: Coliiformes)

A new monotypic genus Colisyringophilus n. g. is established for C. tanzanicus n. sp., quill mites parasitising two mouse bird species from Tanzania, Colius striatus Gmelin and Urocolius macrourus (Linnaeus). This new genus is closely related to Neoaulobia Fain, Bochkov & Mironov, 2000, but differs from it by the following features: the stylophore is rounded posteriorly, the propodonotal shield is reduced to triangular sclerite bearing bases of setae vi and ve, the hysteronotal shield is absent, legs I are longer than legs II, and apodemes I are distinctly elongated. This is the first record of syringophilid mites from hosts of the order Coliiformes.     

Five new species of Rhinonyssidae (Mesostigmata) and one new species of Dermanyssus (Mesostigmata: Dermanyssidae) from birds of Alberta and Manitoba, Canada

Three major lineages of mites are parasitic in the nasal passages of birds, i.e., Rhinonyssidae (Mesostigmata), Ereynetidae (Prostigmata), Cytoditidae, and Turbinoptidae (Astigmata). The most diverse family of avian nasal mites is Rhinonyssidae, which include obligate hematophagous endoparasites of nonratite birds worldwide. Nasal mites have been surveyed extensively in the United States, yet there has never been a Canadian survey. There are only 4 published, and 3 unpublished, rhinonyssid species records from birds in Canada. While surveying the nasal mites associated with birds of Alberta and Manitoba (western Canada), 1 new species of Dermanyssus and 5 new species of Rhinonyssidae were recovered. Herein, I describe and illustrate Dermanyssus diphyes n. sp., Ptilonyssus calvaria n. sp., P. nivalis n. sp., P. pinicola n. sp., P. plesiotypicus n. sp., and Sternostoma setifer n. sp.     

Chromosomal homologies among vampire bats revealed by chromosome painting (phyllostomidae, chiroptera)

Substantial effort has been made to elucidate karyotypic evolution of phyllostomid bats, mostly through comparisons of G-banding patterns. However, due to the limited number of G-bands in respective karyotypes and to the similarity of non-homologous bands, an accurate evolutionary history of chromosome segments remains questionable. This is the case for vampire bats (Desmodontinae). Despite several proposed homologies, banding data have not yet provided a detailed understanding of the chromosomal changes within vampire genera. We examined karyotype differentiation of the 3 species within this subfamily using whole chromosomal probes from Phyllostomus hastatus (Phyllostominae) and Carollia brevicauda (Carolliinae). Painting probes of P. hastatus respectively detected 22, 21 and 23 conserved segments in Diphylla ecaudata, Diaemus youngi, and Desmodus rotundus karyotypes, whereas 27, 27 and 28 were respectively detectedwith C. brevicauda paints. Based on the evolutionary relationships proposed by morphological and molecular data, we present probable chromosomal synapomorphies for vampire bats and propose chromosomes that were present in the common ancestor of the 5 genera analyzed. Karyotype comparisons allowed us to relate a number of conserved chromosomal segments among the 5 species, providing a broader database for understanding karyotype evolution in the family.     

A new genus and four new species of quill mites (Acari: Prostigmata: Syringophiudae) from phasianid birds (Galuformes: Phasianidae)

A new genus and four new species of the quill mites are described. Galliphilopsis gen. n. (G. francolinus sp. n., type species) differs from the closely related Dissonus Skoracki, 1999 by loss of leg setae dGII, the slightly divergent tips of epimeres I and the stylophore constricted posteriorly. Three new species of the genus Galliphilopsis gen. n. and one new species of the genus Mironovia Chirov and Kravtsova, 1995 are described from galliform birds (Phasianidae) collected at the Museum of Natural History, Wroclaw University (Poland): G. lophurus sp. n. from Lophura leucomelanos, G. bochkovi sp. n. from Tragopan sp. and Alectoris barbara, G. francolinus sp. n. from Francolinus levalliantoides, and Mironovia rouloul sp. n. from Rollulus rouloul.     

Bewsiella Domrow (Acarina: Mesostigmata): a revision and the description of new species

The genus Bewsiella is considered to comprise a considerable number of species, despite having been regarded as monotypic. The structure of the male spermadactyl is proposed as a key character for separating congeneric species. This character seems likely to bear phylogenetic information on both the mites themselves and their hosts. Since the male of Bewsiella fledermaus Domrow, the type-species, has not been found, it is impossible to define the morphology of this species based on both sexes. Consequently, all mites that share many characters with the female of B. fledermaus are placed in a B. fledermaus species group. B. aelleni (Till) is considered as a valid species and both sexes and the protonymph are redescribed and illustrated. B. nycteris n. sp., B. emballonuris n. sp., B. cloeotis n. sp., B. haradai n. sp. and B. coelopos n. sp. are described and illustrated. The genus Bewsiella was originally allocated to the family Laelapidae and later transferred to the family Macronyssidae. Recently, the genus was returned to the Laelapidae, and some evidence supporting this action was obtained during the present study, but further studies are required for confirmation.     

Protoresinacarus brevipedis gen. n., sp. n. from Early Cretaceous Burmese amber: the first fossil record of mites of the Family Resinacaridae (Acari: Heterostigmata: Pyemotoidea)

A new genus and species of mites, Protoresinacarus brevipedis gen. n., sp. n. (Acari: Heterostigmata: Pyemotoidea), is described from Early Cretaceous Burmese amber. This represents the first fossil record of a member of the family Resinacaridae. It is represented by 21 phoretic females adjacent to an adult mantidfly (Neuroptera: Mantispidae). This is the first record of phoresy of pyemotid mites on members of the insect order Neuroptera. The fossil mites differ from extant members of the family in possessing distinctly shorter legs I, which do not reach beyond the apex of the gnathosoma, and by the long setae v ₁, v ₂ and c ₂.     

Phylogenetic relationships of Ochoterenatrema Caballero, 1943 (Digenea: Lecithodendriidae) with descriptions of two new species

Ochoterenatrema is a small genus of lecithodendriid digeneans that includes six species parasitic in Neotropical bats in North and South America. Members of this genus are characterized by the presence of a pseudogonotyl formed by thickened tegument on the left side of the ventral sucker. We examined morphology of specimens belonging to five species of Ochoterenatrema from Brazil, Ecuador and the USA and describe two new Ochoterenatrema spp. (Ochoterenatrema sphaerula n. sp. and Ochoterenatrema gracilis n. sp.). These new species are readily differentiated from their congeners by a combination of morphological characters, including the distribution of vitelline follicles and the body shape. We have provided the first DNA sequences for Ochoterenatrema. Newly generated partial nuclear 28S rDNA and mitochondrial cox1 gene sequences were used to differentiate among species and study the phylogenetic affinities of Ochoterenatrema spp., including one of the new species, O. gracilis n. sp., as well as Ochoterenatrema diminutum, Ochoterenatrema fraternum and Ochoterenatrema cf. labda. The phylogeny of the Microphalloidea based on 28S had well-supported topology, particularly at the family level. The Ochoterenatrema clade was strongly supported; however, the internal topology of the clade was weakly supported. Comparison of sequences revealed 0.4–1.3% interspecific divergence in 28S and 9.1–19.7% interspecific divergence in cox1 among Ochoterenatrema spp. We hypothesize that extremely diverse fauna of bats in South and Central America harbors multiple undescribed species of Ochoterenatrema. Several lecithodendriid genera from bats and other hosts are yet to be included in future molecular phylogenetic analyses to test the monophyly of this extremely diverse digenean family and analyze evolutionary affinities of its constituent taxa.     

New findings of gamasid mites belonging to families Laelapidae,Hirstionyssidae, and Haemogamasidae (Acari: Mesostigmata: Gamasina) on bats (Chiroptera)

Our own and previous data concerning the findings of parasitic gamasid mites (Mesostigmata: Gamasina) on bats (Chiroptera), which are not a principal host for them, are analyzed. The gamasid mites under study belong to the following families: Laelapidae Berlese, 1892; Hirstionyssidae Evans, Till, 1966; and Haemogamasidae Oudemans, 1926. In total, 27 species of parasites of the analyzed groups were found on bats. Among them, two species were described for bats for the first time. The medicinal value of this exchange is considered. Possible places where bats have contact with other mammals are discussed.     

New species of the genus Typhlodromus from Sudan (Acari: Phytoseiidae)

The genus Typhlodromus in Sudan includes five species. Of these, three new species are described and illustrated in this work. Individuals of T. sudanicus Elbadry and T. medanicus Elbadry have been found to play an important role in feeding on phytophagous mites and white fly nymphs infesting cotton crop.
Typhlodromus niloticus sp. n. and T. balanites sp. n. from fruit trees feed on tetranychid and eriophyid mites. T. sennarensis sp. n. has been collected from wild plants.
A key is provided for the identification of members of the genus Typhlodromus in Sudan.     

The first find of the feather mite from Apionacaridae family (Astigmata: Analgoidea) on the passerines ( Passeriformes)

A representative of the family Apionacaridae is recorded from the passerine birds Passeriformes for the first time. Fringillosphaera bochkovi gen. n., sp. n. is described from the chaffinch Fringilla coelebs (Fringillidae). The new genus obtains main diagnostic characters as follows. Vertical setae vi absent. Prodorsal shield free from scapular sheilds and epimerites Ia. Humeral sheilds present. Epimerites I convergent, connected by sclerotized plate. Lateral setae f2 and pseudanal setae ps3 absent. Coxal fields I-IV sclerotized. In male: legs IV present, genital apparatus at level of trochanters IV, genital arch with divergent branches. Epiandrium absent. Coxal setae 3a absent. Morphological peculiarities, host associations and phylogenetic relationships of the family Apionacaridae are briefly discussed. It is suggested that this family represents and ancient and relic phylogenetic branch, which had split rather early from the common ancestor of the superfamily Analgoidea in the period of formation of the Neognathae birds.     

Non-kin cooperation in bats

Many bats are extremely social. In some cases, individuals remain together for years or even decades and engage in mutually beneficial behaviours among non-related individuals. Here, we summarize ways in which unrelated bats cooperate while roosting, foraging, feeding or caring for offspring. For each situation, we ask if cooperation involves an investment, and if so, what mechanisms might ensure a return. While some cooperative outcomes are likely a by-product of selfish behaviour as they are in many other vertebrates, we explain how cooperative investments can occur in several situations and are particularly evident in food sharing among common vampire bats (Desmodus rotundus) and alloparental care by greater spear-nosed bats (Phyllostomus hastatus). Fieldwork and experiments on vampire bats indicate that sharing blood with non-kin expands the number of possible donors beyond kin and promotes reciprocal help by strengthening long-term social bonds. Similarly, more than 25 years of recapture data and field observations of greater spear-nosed bats reveal multiple cooperative investments occurring within stable groups of non-kin. These studies illustrate how bats can serve as models for understanding how cooperation is regulated in social vertebrates.     

New deep-sea Tardigrada (Arthrotardigrada,Halechiniscidae) from a manganese nodule area of the eastern South Pacific*

Three new Tardigrada species are described from a manganese nodule area of thc abyssal castern South Pacific. Moebjergarctus mangunis gen. et sp.n. is characterized by its segmcntcd ccphalic cirri, club-shaped and forward bent primary clavae, spherical secondary clavae, spines on legs I, 11, 111, small clavoid papillae on legs IV, long cirri E, and corkscrew-shaped digits with simple claws. Angursa capsula sp.n. is distinguished by the presence of secondary and tertiary clavac, occurring as elevated cuticular areas, club-shaped primary clavae, short lateral cirri, short median cirrus, spines on legs I and hcmisphcrical, capsulc-shaped papillae on legs IV. Angursa lingua sp.n. is characterized by the presence of secondary and tertiary clavae, occurring as elevated cuticular areas, balloon-shaped primary clavae, long lateral cirri, long median cirrus, spines on legs I, clavoid papillae on legs IV and weakly broadened distal parts of cirri E, resulting in tongue-shaped swellings. A simple key to the species of Angursa is presented.     

Rheoptilum: A New Genus of Two-Tailed Baetidae (Ephemeroptera) from Madagascar

Rheoptilum gen. n. is established for R. arni sp. n. and R. lokohensis sp. n. from Madagascar. Imaginal and larval stages are both described. Rheoptilum nymphs have two important adaptations: mouthparts are highly modified for scraping and the habitus is adapted for fast flowing waters. The genus possesses an extremely broad labrum with distal margin almost straight, incisors almost fused, right prostheca long and slender, caudal filament reduced to a single segment, legs long and slender, dorsally bordered with long and thin setae and the body dorsoventrally flattened. This combination of features distinguishes Rheoptilum from other Afro-Malagasy baetid genera. The phylogenetic position of this new genus is discussed.     

Phylogenetic Reconstruction by Cross-Species Chromosome Painting and G-Banding in Four Species of Phyllostomini Tribe (Chiroptera,Phyllostomidae) in the Brazilian Amazon: An Independent Evidence for Monophyly

The subfamily Phyllostominae comprises taxa with a variety of feeding strategies. From the cytogenetic point of view, Phyllostominae shows different rates of chromosomal evolution between genera, with Phyllostomus hastatus probably retaining the ancestral karyotype for the subfamily. Since chromosomal rearrangements occur rarely in the genome and have great value as phylogenetic markers and in taxonomic characterization, we analyzed three species: Lophostoma silvicola (LSI), Phyllostomus discolor (PDI) and Tonatia saurophila (TSA), representing the tribe Phyllostomini, collected in the Amazon region, by classic and molecular cytogenetic techniques in order to reconstruct the phylogenetic relationships within this tribe. LSA has a karyotype of 2n=34 and FN=60, PDI has 2n=32 and FN=60 and TSA has 2n=16 and FN=20. Comparative analysis using G-banding and chromosome painting show that the karyotypic complement of TSA is highly rearranged relative to LSI and PHA, while LSI, PHA and PDI have similar karyotypes, differing by only three chromosome pairs. Nearly all chromosomes of PDI and PHA were conserved in toto, except for chromosome 15 that was changed by a pericentric inversion. A strongly supported phylogeny (bootstrap=100 and Bremer=10 steps), confirms the monophyly of Phyllostomini. In agreement with molecular topologies, TSA was in the basal position, while PHA and LSI formed sister taxa. A few ancestral syntenies are conserved without rearrangements and most associations are autapomorphic traits for Tonatia or plesiomorphic for the three genera analyzed here. The karyotype of TSA is highly derived in relation to that of other phyllostomid bats, differing from the supposed ancestral karyotype of Phyllostomidae by multiple rearrangements. Phylogenies based on chromosomal data are independent evidence for the monophyly of tribe Phyllostomini as determined by molecular topologies and provide additional support for the paraphyly of the genus Tonatia by the exclusion of the genus Lophostoma.     

PERMANENT GENETIC RESOURCES: Development of polymorphic microsatellite loci for the common vampire bat, Desmodus rotundus (Chiroptera: Phylostomidae)

The common vampire bat (Desmodus rotundus) is one of three haematophagous species of bats and the only species in this genus. These New World bats prey on mammals and create significant economic impacts through transmission of rabies in areas where livestock are prevalent. Furthermore, in some portions of their range, it is not uncommon for them to prey upon humans. It is critical to the management of this species and for understanding the spread of bat rabies that detailed studies of D. rotundus population structure be conducted. To further such studies, we have characterized 12 microsatellite loci for this species.     

Fossil onychophorans from Dominican and Baltic amber: Tertiapatus dominicanus n.g., n.sp. (Tertiapatidae n.fam.) and Succinipatopsis balticus n.g., n.sp. (Succinipatopsidae n.fam.) with a proposed classification of the subphylum Onychophora

Abstract. Tertiapatus dominicanus n.g., n.sp. (Tertiapatidae n.fam.) and Succinipatopsis balticus n.gen., n.sp. (Succinipatopsidae n.fam.) (Lobopodia: Onychophora), the first Tertiary fossils of the Lobopodia, are described from Dominican and Baltic amber, respectively. Both families are characterized by the presence of simple legs lacking foot portions with claws and pads. Tertiapatidae is further characterized by soluble body pigments and oral papillae shorter than the legs. Succinipatopsidae is characterized by non-soluble body pigments and oral papillae longer than the legs. Nomenclatural changes include the erection of the class Udeonychophora n. nom. for terrestrial onychophorans with a ventral mouth, the order Ontonychophora n.nom. for extant onychophorans possessing legs with a differentiated "foot" portion, and the family Helenodoridae n.nom. for the genus Helenodora from the Carboniferous. The biogeographical significance of these fossils and their phylogenetic relationship with previously described onychophorans are discussed.     

A new species of Opisthioglyphe (Trematoda: Telorchiidae) from gall bladder of turtles in Malaysia

Opisthioglyphe sharmai n. sp. is described from the gall bladder of the Malayan box turtle, Cuora amboinensis, and the black marsh turtle, Siebenrockiella crassicollis, in Malaysia. The new species is morphologically similar to Opisthioglyphe ranae and some other members of the genus parasitic in amphibians and reptiles. Opisthioglyphe sharmai n. sp. is easily differentiated from all other members of the genus by the cirrus sac extending posterior to the ventral sucker, while in all previously known species the cirrus sac is entirely or mostly preacetabular with the base of the structure not reaching beyond mid-line of the ventral sucker. Despite the overall stable morphology, O. sharmai n. sp. is characterized by highly variable arrangement of testes, from tandem to opposite. It is only the second representative of the genus described from turtles and the first species of Opisthioglyphe parasitic in gall bladder, while all previously described members of the genus are parasitic in the intestine of their hosts.     

First report of Litomosa spp. (Nematoda: Filarioidea) from Malagasy bats; review of the genus and relationships between species

The presence of the filarial genus Litomosa in Malagasy bats is demonstrated by the finding of L. goodmani n. sp. from Miniopterus gleni and Litomosa sp. (male unknown) from M. manavi, both in the Special Reserve of Ankarana. These materials are compared to the 22 Litomosa species, including two Indian species originally placed in the genus Litomosoides, L. fotedari (Gupta and Trivedi, 1989) n. comb. and L. tewarii (Gupta and Trivedi, 1989) n. comb., and the new taxon L. seurati n. sp. (= L. beaucournui Bain, 1966 pro parte), type-host Rhinolophus ferrum-equinum, Algeria, distinguished by the narrow area rugosa and the female caudal extremity with two conspicuous points, instead of several small ones. The Malagasy material belongs to a group of species close to the type, L. filaria, which have a male area rugosa composed of cuticular bosses and microfilariae folded within the sheath, and which are parasitic in Vespertilionidae, Hipposideridae and Rhinolophidae from Africa and Europe. The two Malagasy species resemble L. seurati n. sp., L. beshkovi Jancev, 1971, L. chiropterum Ortlepp, 1932, L. adami Petit, 1980 and L. ottavianii Lagrange et Bettini, 1948, with the enlarged third segment of the buccal capsule. L. goodmani n. sp. is distinct with its small size and female caudal extremity with a single point, which is suppressed in old mature worms; the females of Litomosa sp. have two conical points. Relationships among Litomosa species appear to be dependent upon both the chiropteran host groups and the geographical region.     

A new species and a new record of ectoparasitic mites from thrips in Turkey (Acari: Trombidiidae and Erythraeidae)

Trombidium telletxeae n. sp. is described from a larva parasitic on Odontothrips sp. (Thysanoptera: Thripidae) from Turkey. Grandjeanella multisetosa Zhang & Goldarazena is also reported for the first time in Turkey. A host list for ectoparasitic larval mites on thrips in Turkey is presented.
