The guts of non-predaceous invertebrates in aquatic and moist terrestrial habitats are often colonized by an ecological group of microorganisms called trichomycetes. Taxonomically, these endobionts are currently a diverse, polyphyletic assemblage including both zygomycetous fungi as well as protistan species. Trichomycetes are worldwide in distribution and are from varied habitats, but the species inventory of gut fungi from hosts in Canada is far from complete. We summarize the findings from our earliest surveys (from 1997 to 2005) and collections of candidate dipteran hosts in Nova Scotia. Nine new species of gut fungi are added to the inventory list, including the following seven Smittium spp.: Smittium aggregatum, Smittium gronthidium, Smittium papillum, Smittium pavocaudatum, Smittium radiculans, Smittium sparsum, and Smittium verticillatum, and the following two Stachylina spp.: Stachylina brevicellaris and Stachylina subgrandis. Four of the other 13 Harpellales, Pennella digitata, Smittium megazygosporum, Stachylina penetralis, and Zancudomyces culisetae are reported for the first time in Atlantic Canada. Also recorded is Paramoebidium curvum, with many more specimens of this genus from various locations and hosts included as Paramoebidium spp. only. We suggest that future collections of Diptera, to further document and discover trichomycetes, are warranted across the varied host habitats that abound not only in eastern Canada but the rest of the country as well.

Reported from marine, freshwater, and terrestrial habitats, trichomycetes are an ecological group of both fungi and protists that colonize the guts of insects, crustaceans, and millipedes. Lotic sites (streams, rivers) are a rich source of hosts and their trichomycetes. As part of a larger study of trichomycetes from different aquatic habitats within the Halifax Regional Municipality in Nova Scotia, Canada, one stream from each of three separate watersheds was sampled for aquatic insects, and their guts were dissected and examined for microscopic trichomycetes. Over the course of 17 months, 24 species of trichomycetes were collected including the following four new species: Glotzia gemina sp. nov. R.T. William and Strongman from a mayfly (Baetidae); Stachylina tanysoma sp. nov. R.T. William and Strongman; Smittium ampliboja sp. nov. R.T. William and Strongman; and Smittium insolitum sp. nov. R.T. William and Strongman, all recovered from dipteran (Chironomidae) hosts. New continental records were established for three species including Smittium pusillum Manier & Coste and Stachylina euthena Manier & Coste, both originally described from France, and Smittium nodifixum Strongman & Shengquan Xu previously known only from China. A new regional geographical record for Pennella arctica Lichtw. & M.C. Williams is reported and 17 other species previously known from eastern Canada were recorded. Pteromaktron timberleaense R.T. William & Strongman was described by us from Timberlea, Nova Scotia, but at the time no sexual spores (zygospores) were seen. In the collections reported in this paper, zygospores were found so the original description is emended to include the zygospore features for this species. This report adds to the published data on trichomycetes from Nova Scotia that have appeared over the last 10 years and highlights the significance of long-term sampling in cataloguing the diversity of this group of insect associated microorganisms. We also present some data on seasonal variation in trichomycete occurrence and comment on site specificity in the trichomycetes we collected.

The Chaetosphaeriaceae are a diverse group of pigmented, predominantly phialidic hyphomycetes comprised of several holomorphic genera including Chaetosphaeria, the most prominent genus of the family. Although the morphology of the teleomorphs of the majority of Chaetosphaeria is rather uniform, their associated anamorphs primarily exhibit the variability and evolutionary change observed in the genus. An exception from the morphological monotony among Chaetosphaeria species is a group characterised by scolecosporous, hyaline to light pink, multiseptate, asymmetrical ascospores and a unique three-layered ascomatal wall. Paragaeumannomyces sphaerocellularis, the type species of the genus, exhibits these morphological traits and is compared with similar Chaetosphaeria with craspedodidymum- and chloridium-like synanamorphs. Morphological comparison and phylogenetic analyses of the combined ITS-28S sequences of 35 isolates and vouchers with these characteristics revealed a strongly-supported, morphologically well-delimited clade in the Chaetosphaeriaceae containing 16 species. The generic name Paragaeumannomyces is applied to this monophyletic clade; eight new combinations and five new species, i.e. P. abietinussp. nov., P. eleganssp. nov., P. granulatussp. nov., P. sabinianussp. nov. and P. smokiensissp. nov., are proposed. A key to Paragaeumannomyces is provided. Using morphology, cultivation studies and phylogenetic analyses of ITS and 28S rDNA, two additional new species from freshwater and terrestrial habitats, Codinaea paniculatasp. nov. and Striatosphaeria castaneasp. nov., are described in the family. A codinaea-like anamorph of S. castanea forms conidia with setulae at each end in axenic culture; this feature expands the known morphology of Striatosphaeria. A chaetosphaeria-like teleomorph is experimentally linked to Dendrophoma cytisporoides, a sporodochial hyphomycete and type species of Dendrophoma, for the first time.

During a survey on Eriophyoid Mites in southwest of East Azerbaijan province (Iran), Aceria zygofabae n. sp. and Aceria alkannae n. sp. were found on Zygophyllum fabago L. (Zygophyllaceae) and Alkanna bracteosa Boiss. (Boraginaceae), respectively. They are described and illustrated here. Four further Aceria species were collected and identified as A. eucricotes (Nalepa, 1892), A. cynodonis Wilson, 1959, A. chenopodia Xue, Sadeghi & Hong, 2009 and A. tristriata (Nalepa, 1890) (protogyne and deutogyne). Aceria cynodonis is a new record for Iran Eriophyoid fauna whereas the other species were found for the first time in East Azerbaijan.

Since the first faunistic study of the Pipunculidae (Diptera) of mainland France in 2006, new material from 37 natural sites and four private collections has been evaluated by the authors of this article. A total of 5739 specimens of Pipunculidae collected in France were examined, of which 5214 were identified to species by the authors, for a total of 114 species. DNA analyses were also carried out on some specimens to confirm their morphological identifications. The list of Pipunculidae recorded in mainland France is updated to include 140 species. Tomosvaryella estebani sp. nov. is described from material collected in France and Italy. Twenty-four species are also reported for the first time from France. The records of Cephalops (Semicephalops) carinatus (Verrall, 1901), Cephalosphaera (Cephalosphaera) furcata (Egger, 1860), Eudorylas terminalis (Thomson, 1870) and Jassidophaga villosa (Roser, 1840), without precise data in the literature, are now precisely located in France with this work. For the other species, we provide new post-2006 records.

A cladistic analysis of the genus Melanophora Meigen, 1803 (type-species: Musca grossificationis Linnaeus, 1758 [= Musca roralis Linnaeus, 1758]) is presented and the generic delimitation is critically redefined. The nominal genus-group taxon Bequaertiana Curran, 1929 (type-species: Bequaertiana argyriventris Curran, 1929) is synonymised with Melanophora Meigen syn. nov. The following new combinations are proposed: Melanophora argyriventris (Curran, 1929) comb. nov. and Melanophora basilewskyi (Peris, 1957) comb. nov. Melanophora chia sp. nov. from SW Sardinia is described, illustrated and compared with the other known species of the genus. The male of Melanophora asetosa Kugler, 1978 is described for the first time. Melanophora basilewskyi (Peris, 1957) is recorded from Kenya for the first time.

Within the scorpion genus Vaejovis C.L. Koch, the “mexicanus” group is composed of species distributed in the mountains of México. This group presents taxonomic problems, because its characterization and the species included in the group have varied through the years. In the present work, we redefine this group based on several morphological characters, and we differentiate it from the other two species groups within the genus: “vorhiesi” and “nit dulus+nigrescens”. Additionally, five new species are described: Vaejovis ceboruco sp. nov., Vaejovis nanchititla sp. nov., Vaejovis santibagnezi sp. nov., Vaejovis talpa sp. nov. and Vaejovis tapalpa sp. nov; the males of three species are described for the first time (V. dugesi, V. nigrofemoratus and V. tesselatus); and the updated diagnosis for all species is included. Keys for the identification of males and females of the 30 species included in this group are given. Lastly, notes on the natural history and distribution of some species are provided, with maps of known distribution for all the species.

Abstract:Eighteen species in the lichen genera Acanthothecis Clem. and Fissurina Fée (Graphidaceae) with colourless, trans-septate ascospores are recorded from India. Eight new species, namely Acanthothecis collateralis, Fissurina capsulata, F. coarctata, F. karnatakensis, F. khasiana, F. longiramea, F. taeniocarpoides and F. verrucosa, and a new variety, F. dumastioides var. salazinica, are described. Fissurina saxicola ad int., clearly distinguished from the other species is recorded, but is not formally described as new to science as the material is scanty. Acanthothecis consocians, F. globulifica, F. insidiosa and F. rugosa are reported for the first time from India. A key for the trans-septate species of Acanthothecis and Fissurina in India is provided.

A new species of Darwin wasp of the genus Dicamptus Szépligeti (Hymenoptera: Ichneumonidae: Ophioninae), D. curvus Pham, Matsumoto & Shimizu sp. nov., is described on the basis of type specimen from Lai Chau Province, northwest Vietnam. The new species probably belongs to the giganteus species group and is easily distinguishable from the other species of the group by the smaller indices of fore wing AI and CI as well as the form of sclerites. Two species, D. cantoni Gauld & Mitchell and D. reticulatus (Cameron), are recorded for the first time from Vietnam; and additional distribution records for D. nigropictus (Matsumura) in Vietnam are provided. Through the present study, a total of four Dicamptus species have been recognized in Vietnam and illustrated.

We report a new species of Spermophilus ( Rodentia: Sciuridae), here designated as S. torosensis sp. nov., distributed in the Taurus Mountains in southern Anatolia, Turkey. A total of 161 specimens of the genus Spermophilus from Turkey and Iran were analyzed for their morphological, morphometric, and karyological characteristics. Uni- and multi-variate statistical analyses of morphologic data for 95 adult specimens yielded 4 distinct groups. Taxonomic evaluations classified the specimens into 4 species Spermophilus citellus, S. xanthopymnus, S. fulvus and S. torosensis sp. nov. Morphometrics, coat coloration, a brush-shaped tail, and a NFa value of 72 are diagnostic characters that distinguish S. torosensis sp. nov. from the other species. In Turkey, S. torosensis sp. nov. was found in 6 locations. The karyotype of S. fulvus also is described for the first time as 2n= 36, NFa= 70 and NFa= 66; new karyotypic data is reported for S. xanthoprymnus from Iran and Turkey.
