AbstractThe family Nemasomatidae is redefined to include onty genera with all sterna secondarily free from pleurotergites. Comments are given on the included genera, viz., Antrokoreana, Basoncopus gen. n. (type-species B. filiformis sp. n.) (Kazakhstan), Dasynemasoma, Thalassisobates, Sinostemmiulus, Nemasoma, and Orinisobates. Isobates coiffaiti Demange, 1961 is synonymized with Thalassisobates littoralis (Silvestri, 1903). Orinisobates is revised and shown to include O. soror sp. n. (Kuril Islands), O. microthylax sp. n. (Kamchatka and Siberia), O. gracilis (Verhoeff, 1933) (NW China), O. sibiricus (Gulicka, 1963) (Altai region, Kazakhstan), O. kasakstanus (Lohmander, 1933) (Kazahkstan), O. nigrior (Chamberlin, 1943) (eastern United States), O. utus (Chamberlin, 1912) (northwestern United States), and O. expressus (Chamberlin, 1941) (northwestern United States and adjacent Canada). Mimolene oregona Chambertin, 1941 and M. sectile Loomis & Schmitt, 1971 are synonymized with O. expressus. A possible case of parthenogenesis in O. microthylax is recorded. Evidence is presented for the following sister-group relationships: Antrokoreana + (Basoncopus + (Dasynemasoma + (Thalassisobates + (Sinostemmiulus + (Orinisobates + Nemasoma))))). The position of Basoncopus is uncertain, and O. soror may belong in a separate genus and constitute the sister-group of Orinisohates + Nemasoma. If soror does belong in Orinisobates, it is the sister-group of all its congeners. The American species of Orinisobates are shown probably to constitute a monophyietic group. The family is suggested to have originated in the eastern Palearctic region, Orinisobates having invaded North America via the Bering Bridge. Doubtful species and species erroneously assoiciated with the Nemasomatidae are listed. The genera Okeanobates and Yosidaiulus are excluded from the family and referred to Okeanobatidae stat. n. in superfamily Blaniuloidea. The genera Trichonemasoma, Telsonemasoma, and Chelojulus are also excluded from the Nemasomatidae and relegated to Julida incertae sedis.

Examination of museum specimens belonging to the cyphophthalmid Gondwanan family Pettalidae has rendered a collection of specimens placed in the new genus Karripurcellia. The genus includes three species, K.�peckorum, sp. nov., K. sierwaldae, sp. nov. and K. harveyi, sp. nov., from the Pemberton area in Western Australia. These are the first cyphophthalmid species found outside Queensland in Australia. Karripurcellia, gen. nov. is distinguished from other Australian pettalids by the lack of modifications in the anal plate, as well as the lack of the typical male anal glands of pettalids, sironids and the stylocellid genus Fangensis Rambla, 1994. Two of the species, K. peckorum, sp. nov. and K. sierwaldae, sp. nov., live sympatrically and have been collected in the same litter samples in one locality. The proposition of the new genus is accompanied by a cladistic analysis of all pettalid genera and most species within each genus, with the exception of the species-rich genus Rakaia Hirst, 1925. The cladistic analysis supports the monophyly of the Karripurcellia, gen. nov. species, but their sister-group relationships are unclear. However, the remaining Australian species cluster with the pettalids from New Zealand and South Africa, but not with Karripurcellia, sp. nov.

Molecular Characters

The Helvellaceae encompasses taxa that produce some of the most elaborate apothecial forms, as well as hypogeous ascomata, in the class Pezizomycetes (Ascomycota). While the circumscription of the Helvellaceae is clarified, evolutionary relationships and generic limits within the family are debatable. A robust phylogeny of the Helvellaceae, using an increased number of molecular characters from the LSU rDNA, RPB2 and EF-1α gene regions (4 299 bp) and a wide representative sampling, is presented here. Helvella s.lat. was shown to be polyphyletic, because Helvella aestivalis formed a distant monophyletic group with hypogeous species of Balsamia and Barssia. All other species of Helvella formed a large group with the enigmatic Pindara (/Helvella) terrestris nested within it. The ear-shaped Wynnella constitutes an independent lineage and is recognised with the earlier name Midotis. The clade of the hypogeous Balsamia and Barssia, and H. aestivalis is coherent in the three-gene phylogeny, and considering the lack of phenotypic characters to distinguish Barssia from Balsamia we combine species of Barssia, along with H. aestivalis, in Balsamia. The closed/tuberiform, sparassoid H. astieri is shown to be a synonym of H. lactea; it is merely an incidental folded form of the saddle-shaped H. lactea. Pindara is a sister group to a restricted Helvella, i.e., excluding the /leucomelaena lineage, on a notably long branch. We recognise Pindara as a separate genus and erect a new genus Dissingia for the /leucomelaena lineage, viz. H. confusa, H. crassitunicata, H. leucomelaena and H. oblongispora. Dissingia is supported by asci that arise from simple septa; all other species of Helvellaceae have asci that arise from croziers, with one exception being the /alpina-corium lineage of Helvella s. str. This suggests ascus development from croziers is the ancestral state for the Helvellaceae and that ascus development from simple septa has evolved at least twice in the family. Our phylogeny does not determine the evolutionary relationships within Helvella s.str., but it is most parsimonious to infer that the ancestor of the helvelloids produced subsessile or shortly stipitate, cup-shaped apothecia. This shape has been maintained in some lineages of Helvella s.str. The type species of Underwoodia, Underwoodia columnaris, is a sister lineage to the rest of the Helvellaceae.

New Discovery

A new wood wasp, Cratosirex sennlaubi gen. et sp. nov., is described and figured from one specimen collected from the Lower Cretaceous Crato Formation in northeastern Brazil. This new genus is placed in the new siricid subfamily Cratosiricinae subfam. nov., based on a combination of plesiomorphic and autapomorphic characters. The presence of small and sub-equal forewing cells 1R1 and 2R1 is a synapomorphy with the extant subfamily Siricinae, absent in the other extinct subfamilies †Auliscinae and †Gigasiricinae, supporting a sister group relationships with the Siricinae. Our new discovery expands the distribution range of Siricidae fossil records, highlights the antiquity of the family, and emphasizes the need for more studies of this particular insect lineage in the Mesozoic deposits. Currently, all the representatives of the crown group of the extant Siricidae are Cenozoic.

A New Species

The Epicopeiidae is a small geometroid family distributed in the East Palaearctic and Oriental regions. It exhibits high morphological diversity in body size and wing shape, while their wing patterns involve in various complex mimicry rings. In the present study, we attempted to describe a new genus, and a new species from Vietnam, with comments on two assumed congeneric novel species from China and India. To address its phylogenetic affinity, we reconstructed the phylogeny of the family by using sequence data of COI, EF-1α, and 28S gene regions obtained from seven genera of Epicopeiidae with Pseudobiston pinratanai as the outgroup. We also compared the morphology of the new taxon to other epicopeiid genera to affirm its taxonomic status. The results suggest that the undescribed taxon deserve a new genus, namely Mimaporia gen. n. The species from Vietnam, Mimaporia hmong sp. n., is described as new to science. Under different tree building strategies, the new genus is the sister group of either Chatamla Moore, 1881 or Parabraxas Leech, 1897. The morphological evidence, which was not included in phylogenetic analyses, however, suggests its potential affinity with Burmeia Minet, 2003. This study also provides the first, although preliminary, molecular phylogeny of the family on which the revised systematics and interpretation of character evolution can be based.

Paraleucopidae Wheeler fam. nov. is proposed for the previously unplaced New World genera Paraleucopis Malloch, Mallochianamyia Santos-Neto and Schizostomyia Malloch and undescribed Australian species. A key to genera of Paraleucopidae is provided. Paraleucopis is revised and includes nine species: P. auripes Wheeler & Sinclair sp. nov. (type locality: Andalgala, Argentina); P. bispinosa Wheeler & Sinclair sp. nov. (type locality: Socos, Coquimbo, Chile); P. boharti Wheeler & Sinclair sp. nov. (type locality: Andalgala, Argentina); P. boydensis Steyskal (type locality: nr. Palm Desert, California, USA); P. corvina Malloch (type species of genus; type locality: New Mexico, USA); P. mexicana Steyskal (type locality: Kino Bay, Mexico); P. nigra Wheeler & Sinclair sp. nov. (type locality: Portal, Arizona, USA); P. paraboydensis Wheeler & Sinclair sp. nov. (type locality: Willis Palms Oasis, California, USA); P. saguaro Wheeler & Sinclair sp. nov. (type locality: Usery Mtn Park, Arizona, USA). A key to the species of Paraleucopis is provided. The distribution of Paraleucopis is disjunct, with six species in the western United States and northwestern Mexico and three species in northern Chile and northern Argentina.                The sister group and superfamilial assignment of the Paraleucopidae cannot be established based on current knowledge although the family has affinities to some families of the Asteioinea sensu J.F. McAlpine. A well-supported hypothesis on the relationships of the families of the Acalyptratae will be required before the sister group relationships of Paraleucopidae can be determined.

Great Divergence

Recently, an undescribed marine ciliate was isolated from China. Investigation of its morphology and infraciliature revealed it as an undescribed species representing a new genus, Eurystomatella n. gen., the type of the new family Eurystomatellidae n. fam. The new family is defined by close-set, apically positioned oral membranelles and a dominant buccal field that is surrounded by an almost completely circular paroral membrane. The new genus is defined by having a small oral membranelle 1 (M1), bipartite M2 and well-developed M3, a body surface faintly sculptured with a silverline system in a quadrangular, reticulate pattern and a cytostome located at the anterior third of a large buccal field. The type species of the new genus, Eurystomatella sinica n. sp., is a morphologically unique form that is defined mainly by the combination of a conspicuously flattened body, several caudal cilia, extremely long cilia associated with the buccal apparatus and a contractile vacuole located subcaudally. According to phylogenetic analyses of small-subunit (SSU) rRNA gene sequences, Eurystomatella clusters with the genus Cyclidium, as a sister group to the family Pleuronematidae. The great divergence in both buccal and somatic ciliature between Eurystomatella and all other known scuticociliates supports the establishment of a new family for Eurystomatella.

Our present knowledge of the Strongylid parasites of reptiles is based primarily on Dujardin (1845), who refers all the forms along with those of other vertebrates under a common genus Strongylus, and described four species from the reptilian hosts. Since then our knowledge of parasitic fauna has considerably increased, and von Linstow (1878–89) gave an enlarged list under the same genus from reptiles and also a few under the genus Kalicephalus, Later, with improved methods of Nematode study the forms described were revised, and it was found necessary to split the genus Strongylus, and several groups of a diverse character were recognised. The genus Strongylus was thus split up into several genera, and some of them were removed from the family Strongylidæ. The form Strongylus dispar of Dujardin from the Anguis fragilis was removed into a separate genus, Oswaldocruzia and Strongylus auricularis, with its characters in the absence of buccal capsule and the bifid and trifid distal ends of the spicule seemed more closely allied to Trichostrongylidæ Leiper, and was also removed to the genus Oswaldocruzia.

High Degree

A new genus and species of arionid slug, Kootenaia burkei n. gen. et n. sp., are formally described from northern Idaho, United States. This taxonomic decision is based on comparative anatomical and molecular data involving representatives of a total of ten species and three additional genera (Hemphillia, Prophysaon, and Zacoleus) of the family Arionidae. The anatomical analyses show that the new genus is characterized by a major autapomorphy, the complete absence of an epiphallus, which is found in all other arionids. The molecular analyses using two mitochondrial genes and the anatomical data produce congruent topologies. Overall, there is a high degree of concordance between the anatomical and molecular datasets.
