A new classification for the subgenera of the genus Acanthophthirius Perkins,with descriptions of twelve new taxa (Acarina,Trombidiformes, Myobiidae)

The myobiid genus Acanthophthirius Perkins, to date comprising four subgenera, is reviewed and divided into just two subgenera, the nominate subgenus and Myotimyobia Fain. The male genital shield and female opisthogastric sclerites, which are here considered to be part of female genitalia, are adopted as the criteria for dividing the subgenera. These structures are essentially the same in form and position in the subgenus Acanthopthirius in its revised sense, while they are both more heterogeneous in species of the redefined subgenus Myotimyobia. The subgenera Acanthophthirius Fain and Chiromyobia Fain are thought to represent species-groups in the nominate subgenus, named respectively the etheldredae and miniopteri groups. The following one new subspecies and 11 new species are described: A. (A.) womersleyi eptesicus, A. (A.) glauconycteris, A. (A.) mauritaniensis, A. (A.) philetoris, A. (A.) otonycteris, A. (A.) steatocaudatus, A. (A.) nyctophilis, A. (M.) vagus, A. (M.) longus A. (M.) baueris, A. (A.) hesperopteris (female only) and A. (M.) pixonixeos (female only). A. (M.) hanensis is synonymised with A. (M.) namurensis, and A. (M.) capacini is emended to A. (M.) capaccinii and relegated to a subspecies of A. (M.) myotis. All the known and new species are assigned to their respective subgenera and shown in a table. Incongruent host-relationships of some of the mites are clarified, although not completely solved, by the introduction of the new classification for the subgenera.     

Notes on some poorly known species of the genus Neocheyletiella Baker, 1949 (Acari,Cheyletidae) with a key to the genus

Summary The genus Neocheyletiella Baker, 1949 is redefined and the following species are redescribed and figures given for the first time: N. media Fain, 1972; N. avicola Fain, 1972; N. amandavae Fain, 1972; N. pittae Fain, 1972; N. siva Fain, 1972. N. oudemansi Volgin, 1969 is placed in the synonymy of N. microrhynchus (Berlese & Trouessart, 1889). N. heteropalpus (Megnin, 1878) is presumed to belong to the genus Apodicheles Fain, 1979 although the type material of that species is probably lost. A new nomenclature for the idiosomal chaetotaxy is proposed for the males of Neocheyletiella spp. and of Cheyletus malaccensis Oudemans. A key is given to the females and males of the species of genus Neocheyletiella. ac]19800106     

Pneumonyssus africanus Fain, 1959 (Acari,Mesostigmata). Comparison of larva and adults with P. simicola Banks, 1901

Summary The lung mite P. africanus Fain, 1959 and its larva from a new host (Mandrillus leucophaeus) is described and compared to the most frequently found species, P. simicola Banks, 1901. The chaetotaxy of the legs is essentially identical, but leg IV of P. simicola bears 5 spines and 10 setae, while in P. africanus one of the spines is replaced by a seta. Also, very fragile small setae were discovered at the base of the ambulacra on legs II, III and IV in P. africanus and only on leg IV in P. simicola. The chaetae of the ‘Haller's organ’ on leg I are described in detail, and formulae for the chaetotaxy of all legs and measurements of both species are given. ac]19860213

Revision of Entomelas Travassos, 1930 (Nematoda: Rhabdiasidae) with a review of genera in the family

Summary Entomelas entomelas (Dujardin, 1845) Travassos, 1930, the type species of Entomelas, is redescribed based on specimens from Anguis fragilis and Ophisaurus apodus. The generic diagnosis is emended. E. dujardini (Maupas, 1916) Travassos, 1930, Paraentomelas kazachstanika (Sharpilo & Vakker, 1972) Sharpilo, 1976 and Hexadontophorus ophisauri Kreis, 1939 are synonymized with E. entomelas and the genera Paraentomelas and Hexadontophorus fall as synonyms of Entomelas. Kurilonema Szczerbak & Sharpilo, 1969 is synonymized with Entomelas and the type species, K. markovi, is reclassified as Entomelas markovi (Szczerbak & Sharpilo, 1969) n. comb. Entomelas cruszi n. sp. is described from agamid lizards of Sri Lanka. The genera in the Rhabdiasidae are reviewed and a key is provided. Ophiorhabdias Yamaguti, 1943 and Shorttia Singh & Ratnamala, 1977 are designated synonyms of Rhabdias Stiles & Hassall, 1905. ac]19790201     

The subgenus Ashima (Diptera,Drosophildae, Phortica) from China,with DNA barcoding and descriptions of three new species

In the present study, three new species found in Yunnan, Southwest China were described as members of the subgenus Phortica (Ashima): P. (A.) haba An & Chen, sp. nov., P. (A.) montipagana An & Chen, sp. nov. and P. (A.) qingsongi An & Chen, sp. nov. Barcode sequences (partial sequences of the mitochondrial COI gene) were collected from 61 specimens of 16 known and the above-mentioned three new Ashima species. The intra- and interspecific pairwise K-2P (Kimura two-parameter) COI distances were analysed and a phylogenetic tree was constructed based on the barcode sequences. Species delimitation in this subgenus was supported by integrating barcodes with morphological information, in particular for the three new species, considered to be cryptic species. In addition, the diversification of lineages in the subgenus Ashima was proposed to occur in southern China and adjacent areas, suggesting specific adaptation of Ashima species to the high plateau environments.

Chromosome differences in Peromyscus maniculatus populations at different altitudes in Colorado

Mice of the genus Peromyscus all have 48 chromosomes. Yet the appearance of the 48 chromosomes is highly variable from species to species (Hsu & Arrighi, 1966, 1968, 1971; Pathak et al., 1973) and even in different populations of the same species (Sparkes & Arakaki, 1966; Ohno et al., 1966; Hsu & Arrighi, 1968; Arakaki et al. 1970; Te & Dawson, 1971; Bradshaw & Hsu, 1972; Murray & Kitchin, 1976). The evolutionary significance of this variation and the mechanisms for its initiation and maintenance have been of interest for quite a few years. However, it was not until the sophisticated chromosome banding techniques became available that mammalian cytogeneticists were able to begin to study the chromosome variation of Peromyscus in some detail. The use of C-banding led Hsu & Arrighi (1971) to the finding that the short arms of chromosomes in three different species of Peromyscus contained constitutive heterochromatin. These results suggested that the variations in the number of acrocentric chromosomes in Peromyscus might be a result of different amounts of heterochromatin. Later studies (Duffey, 1972; Waterbury, 1972; and Pathak et al., 1973) were also consistent with this hypothesis.However, it was soon discovered that not all chromosomal differences among Peromyscus populations are due to heterochromatin changes. Studies by Arighi et al. (1976) and Murray & Kitchin (1976) showed that some chromosomal differences between species and subspecies of Peromyscus are due to pericentric inversions. Thus, it appears that both inversions and the addition of heterochromatin are involved in the evolution of the karyotype of Peromyscus.The purpose of our study was to investigate the chromosomes of Peromyscus maniculatus in different populations in Colorado (U.S.A.) and to test for relationships involving an altitudinal gradient. In the first part of this study, orcein stained chromosomes from three subspecies of mice sampled at nine different altitudes were examined for karyotype variability. In the second part of the study, karyotypes of two subspecies (P. m. rufinus and P. m. luteus), representing high and low altitude populations were examined with Q banding to determine the mechanisms responsible for chromosomal differences.     

Two new taxa of subtribe Rhaconotina (Hymenoptera: Braconidae,Doryctinae, Doryctini) from Africa,with a key to subtribe genera

A new genus, Grangerdoryctes gen. n. (with type species Aivalykus niger Granger), from Madagascar and a new subgenus Pararhacon subgen. n. of the genus Rhaconotus Ruthe (type species R. (P.) haeselbarthi sp. n.) from South Africa are described and illustrated. A discussion of genera without a second radiomedial vein of the fore wing in the tribe Doryctini is presented. The position and content of the subtribe Rhaconotina are discussed and a key for determination of the genera of this subtribe is proposed.     

A new genus and species of quill mites (Acari: Syringophilidae) from a king bird-of-paradise <Emphasis Type="Italic">Cicinnurus regius</Emphasis> (L.)

Neoperisterophila regiusi n. g., n. sp. is described from the quills of Cicinnurus regius (L.) (Passeriformes: Paradisaeidae) from New Guinea. This new genus belongs to the Peristerophila generic group. It differs from other four genera of this group, Peristerophila Kethley, 1970, PsittaciphilusFain et al., 2000, Castosyringophilus Bochkov & Perez, 2002 and Terratosyringophilus Bochkov & Perez, 2002 by the absence of the propodosomal and hysterosomal shields in the females.     

Taxonomic notes on Weissia subgenus Astomum,including Weissia wilsonii D.A.Callaghan,a new species from Europe

Introduction. The present study investigates the taxonomy of European members of Weissia Hedw. subgenus Astomum Hampe., a group considered taxonomically difficult and including species of high conservation concern.

Methods. A broad set of samples were subject to DNA sequencing and morphological analysis, plus a review of type material was undertaken.

Key Results and Conclusions. Three taxonomic additions and changes are supported. (1) Weissia longifolia var. angustifolia (Baumgartner) Crundw. & Nyholm is raised to species rank, W. angustifolia (Baumgartner) D.A.Callaghan, comb. et. stat. nov. (2) The type of W. multicapsularis (Sm.) Mitt. comprises an intermix of Phascum cuspidatum Hedw. and W. longifolia Mitt., and the protologue refers to unique features of P. cuspidatum but no such features of W. longifolia. Weissia multicapsularis is therefore described as a new synonym of P. cuspidatum. (3) Plants that have been named as W. multicapsularis by modern authors comprise an undescribed species, here named W. wilsonii D.A.Callaghan, sp. nov. An illustrated key to European species of Weissia subgenus Astomum is provided.     

Cestodes of birds from the Ivory Coast. Species of the genus Anonchotaenia Cohn, 1990

Five taxa included in the cestode genus Anonchotaenia (Cyclophyllidea, Paruterinidae) have been found in various birds from the Ivory Coast (West Africa). The hosts belong to the families Hirundinidae and Corvidae. A. (Paranonchotaenia) prionopos n. sp., parasitic in Prionops plumata, and A. (P.) malaconoti n. sp, parasitic in Malaconotus blanchoti, are placed in a new subgenus named Paranonchotaenia, which is erected for the Anonchotaenia species showing genital ducts passing between the longitudinal excretory stems. A. (P.) prionopos is characterised by a rather short cirrus-pouch, six to seven testes, and an integumental cavity at the distal extremity of the cirrus-pouch in gravid proglottides. A. (P.) malaconoti differs from the former species mainly by the larger cirrus-pouch and a slightly greater number of testes. The other three species are A. longiovata, parasitic in Hirundo semirufa; A. globata, parasitic in Psadiloprocne obscura (the latter two species are recorded from new hosts and new geographical areas); and Anonchotaenia sp., parasitic in Hirundo rustica. It is assumed that the subgenus A. (Anonchotaenia) is rather a parasite of the Passerida and that the subgenus A. (Paranonchotaenia) tends to be parasitic in the Corvida.This paper is a part of the author's thesis.This paper is a part of the author's thesis.     

Taxonomic status of Amebachia Uchida in the genus Netelia Gray (Hymenoptera; Ichneumonidae; Tryphoninae) with descriptions of four new species from Japan

The lectotype of Amebachia baibarana Uchida, 1928, which is the type species of Amebachia Uchida, was re‐examined. Though this species was synonymized with Netelia (Netelia) laevis (= Paniscus laevis Cameron, 1905) and Amebachia has been synonymized under the subgenus Netelia of the genus Netelia, it is concluded that A. baibarana is a distinct species from N. laevis and Amebachia should be a subgenus of the genus Netelia. Netelia laevis is transferred from the subgenus Netelia to Apatagium. Four new species of Netelia (Amebachia), N. (A.) yoshimatsui sp. nov., N. (A.) rasilella sp. nov., N. (A.) fulvistigma sp. nov., and N. (A.) vicinalis sp. nov. are described from Japan, and a key to the species of this subgenus is provided.     

Five new species and a new subgenus of the mite genus <Emphasis Type="Italic">Premicrodispus</Emphasis> (Acari,Heterostigmata, Microdispidae) from Turkmenistan

A new monotypic subgenus, Premicrodispulus subgen. n., with the type species Premicrodispus reductus sp. n., and four new species of the nominative subgenus of the mite genus Premicrodispus, P. (Premicrodispus) paradoxus sp. n., P. (P.) heterocaudatus sp. n., P. (P.) obtusisetosus sp. n., and P. (P.) incisus sp. n., collected in soils of Turkmenistan are described. The subgenus Premicrodispulus subgen. n. differs from the nominative subgenus in the presence of 3 setae on genu I (seta l″ absent) and 1 seta on genu II (setae d and l″ absent). Premicrodispus (Premicrodispus) paradoxus sp. n. differs from all the species of the genus in the presence of solenidion on tarsus III. P. (P.) heterocaudatus sp. n. is most similar to P. longisetosus (Mahunka, 1970), but differs in the setae ps3 distinctly longer than ps ₁ (in P. longisetosus, ps ₃ and ps ₁ are similar in length). P. (P.) obtusisetosus sp. n. is most similar to P. montanus Khaustov, 2006, but differs in obtuse setae c ₁, e, and f (in P. montanus, these setae are pointed); P. (P.) incisus sp. n. is most closely related to P. longisetosus (Mahunka, 1970), but differs in the presence of distinct excavations on the posterior margin of tergites C and D (in P. longisetosus, excavations are absent).     

Natural enemies ofPlutella xylostella (Lep.: Plutellidae) on crucifers in Honduras

Three primary parasitoids in three genera were reared fromPlutella xylostella (L.) larvae and pupae collected in various crucifer producing regions of Honduras. The ichneumonidDiadegma insulare (Cresson) was by far the most abundant species. TwoSpilochalcis species, facultative hyperparasitoids attackingP. xylostella andD. insulare, were encountered as well as eleven species in nine genera of obligate hyperparasitoids attackingD. insulare. Three vespid predators are noted as predating on larvae.      

Neottialges (Pelecanectes) ibisicola sp. n. (Acari: Hypoderidae) from the subcutaneous tissues of the white-faced ibis, Plegadis chihi (Ciconiiformes: Threskiornithidae)

Neottialges (Pelecanectes) ibisicola sp. n. is described from the subcutaneous tissues of the White-faced Ibis, Plegadis chihi, from west Texas. The new species is similar to N. (P.) plegadicola Fain, but differs from this and other species of the subgenus by idiosomal chaetotaxy, presence of a bifurcate apical extension on Tarsus III, solenidion phi on Tibia I less than 1/2 as long in the new species, lateroventral seta of Tibia I whiplike, structure of the genital sclerite and suckers, and presence of punctations on the dorsal idiosoma. The morphology and host-parasite relationships of the new species are compared with those of related species of hypopi from the host family Threskiornithidae.     

Phylogeny and taxonomic revision of all genera of Conopidae (Diptera) based on morphological data

All global genera of the fly family Conopidae are revised here. A cladistic analysis of 117 morphological characters recorded from 154 species, including representatives of 59 genera and subgenera, recovers a phylogenetic hypothesis for the family. This hypothesis is used as the basis of a new classification for the family. Both Sicini and Zodionini are removed from Myopinae and elevated to subfamilial status. A new tribe, Thecophorini, is proposed within Myopinae to accommodate Thecophora, Scatoccemyia, and Pseudoconops. Two genera, Pseudomyopa and Parazodion, are removed from Dalmanniinae and placed in Myopinae and Zodioninae, respectively. Conopinae is divided into 11 tribes, seven of which are newly described (Asiconopini, Caenoconopini, Gyroconopini, Microconopini, Neoconopini, and Siniconopini). Some examined species are transferred to different or new genera and subgenera. A new genus, Schedophysoconops gen. nov. , and subgenus Asiconops (Aegloconops) subgen. nov. within Conopinae are described. A review of character evolution and phylogeography is included in light of the new classification. A catalogue of all genus‐group names is included with new emendations noted.     

Taxonomic revision of the genus Dolophilodes subgenus Dolophilodes (Trichoptera: Philopotamidae) of Japan

Japanese species of the genus Dolophilodes subgenus Dolophilodes are revised taxonomically. Seven described species are recognized: D. japonicus (Banks), D. shinboensis (Kobayashi), D. auriculatus Martynov, D. nomugiensis (Kobayashi), D. babai (Kobayashi), D. iroensis (Kobayashi) and D. commatus (Kobayashi). In addition, two new species, D. angustatus and D. dilatatus, are described. Males of all nine species and females of all but D. babai are described and illustrated. The subgenus Hisaura Kobayashi is synonymized under the subgenus Dolophilodes. Three synonymies of species proposed are Wormaldia triangulata Kobayashi under D. nomugiensis, D. kunashirensis Ivanov under D. iroensis and Sortosa kaishoensis Kobayashi under D. commatus.     

A review of fur-mites of the genus <Emphasis Type="Italic">Dubininetta</Emphasis> Fain &amp; Lukoschus, 1978 (Acariformes: Listrophoridae), ectoparasites of moles (Soricomorpha: Talpidae)

The fur mite genus Dubininetta Fain & Lukoschus, 1978 (Acariformes: Listrophoridae) represented by ectoparasites of moles (Soricomorpha: Talpidae) is revised. An amended diagnosis of this genus is provided. Two new species are described from moles in Vietnam: Dubininetta euroscaptor n. sp. from Euroscaptor parvidens (Miller) and Dubininetta abramovi n. sp. from Euroscaptor subanura Kawada, Son & Can. The insufficiently described D. taiwanensis (Fain & Lukoschus, 1978) from Mogera insularis (Swinhoe) (type-host) is redescribed based on the type-specimens and numerous newly collected in the Russian Far East specimens from Mogera robusta Nehring. The host ranges are considered for all species of Dubininetta. A key to the five species presently known in this genus is provided.
