Rhagodiinae: A new subtribe in the Chenopodiaceae

A new subtribe, Rhagodiinae, is described in the tribe Chenopodieae of the Chenopodiaceae. Three genera are included in this new subtribe: Rhagodia with 8 species, Einadia with 3 species, and Holmbergia with a single species. All the species are fully described and keys to the genera and species are given. Four new combinations are proposed: Rhagodia deltophylla, Einadia nutans, Einadia hastata and Einadia triandra.     

A new taxonomy of the family Teloschistaceae

The lichen family Teloschistaceae is one of the larger families of lichenized fungi. Currently it includes one very large heterogenous genus, Caloplaca, with some 1000 or more species with a vast variation in morphology, anatomy and chemistry. The rest of the family is split into 10–15 smaller genera, each with 20 or fewer species. There is no modern classification of the family based on molecular data. Here we attempt a first phylogenetic evaluation of a large part of the family, including a total of 337 species. Of these, 162 were used in a combined phylogenetic analysis of the ribosomal RNA sequence markers nrITS, nrLSU and mrSSU, using Bayesian inference. We also analysed all species using nrITS data, split into four different analyses. As a result we propose a new classification of the family, where a total of 39 genera are recognized, of which 31 are newly described or resurrected. The new genera are: Athallia, Austroplaca, Bryoplaca, Calogaya, Cerothallia, Flavoplaca, Gondwania, Haloplaca, Orientophila, Pachypeltis, Parvoplaca, Rufoplaca, Shackletonia, Scutaria, Sirenophila, Solitaria, Squamulea, Stellarangia, Teloschistopsis, Usnochroma, Variospora, Villophora and Wetmoreana. Resurrected genera are Blastenia, Dufourea, Follmannia, Gyalolechia, Leproplaca, Polycauliona, Pyrenodesmia and Xanthocarpia. The species Orientophila subscopularis is described as new. A third subfamily, Teloschistoideae, is proposed to accommodate the genus Teloschistes and related genera, parallel to the two previously recognized subfamilies Xanthorioideae and Caloplacoideae. We also show the large plasticity in both morphological and anatomical characters between closely related species within genera, indicating the low value of these as evolutionary markers. The secondary chemistry is a better marker in some parts of the family. We recognize a large number of geographically delimited clades with clear centres of evolution, but often showing large variation in morphology and anatomy.

Yasumatsusa Togashi, 1970 and Aproceros Malaise, 1931 are recorded for the first time from South Korea. A new species, Yasumatsua koreana Lee & Lee sp. nov., and newly recorded species, Aproceros pallidicornis (Mocsáry, 1909), are described. Photographs of the new species and a key to genera of Korean Sterictiphorinae are provided.     

Seven new genera of dorylaimid nematodes from Colombian rain forest

Summary New genera described from soil in Colombian rain forest are Fuscheila (Thornenematidae), Capilonchus (Tylencholaiminae, Tylencholaimidae), Caveonchus (Tyleptinae, Leptonchidae), Coronatyleptus (Belonenchinae, Leptonchidae), Promumtazium (Mumtaziinae, Tylencholaimidae), Tantunema (Thorniinae, Tylencholaimidae) and Zalophidera (Xiphinemellinae, Tylencholaimidae). 12 new species belonging to these genera described and illustrated are: Fuscheila citrifera (type species), F. godmanae, Capilonchus lineatus (type-species), Caveonchus colombicus (type species), C. brevisaccus, Coronatyleptus barbarae, C. curvus, C. robustus, Promumtazium pyxidorum (type species), Tantunema bothriocephalum (type species), Zalophidera tylocephala (type species) and Z. idiostoma. Caveonchus saccatus (Goseco, Ferris & Ferris, 1981) n. comb. and Coronatyleptus coronatus (Siddiqi & Khan, 1965) n. comb. (type-species) are made for Basirotyleptus saccatus and B. coronatus, respectively. The composition of the families Leptonchidae and Tylencholamidae is discussed and Leptonchoidae Thorne, 1935 (Ferris, 1970) is made a junior synonym of Tylencholaimoidea Filipjev, 1934 (n.rank). ac]19810621     

Furcarcturus polarsterni gen. nov., sp. nov., a large deep-sea arcturid isopod from the Drake Passage, with a preliminary molecular characterization

A new arcturid species of unusual size (> 6 cm) is described from a locality in the Drake Passage at 3720 m depth. Due to the unique combination of characters found in these isopods, the new genus Furcarcturus is proposed. Sequences of the 16S rRNA gene obtained from eight species indicate that the new species does not belong to groups of species currently placed in the genera Antarcturus and Chaetarcturus. More sequences are needed to corroborate arcturid phlylogeny. Accepted: 28 May 2000     

The Labidocarpine mites (Acari: Chirodiscidae) from oriental bats. IV. Genera Olabidocarpus Lawrence, 1948, Dentocarpus Dusbabek & Cruz, 1966, Labidocarpellus Fain, 1976 and Pteropiella Fain, 1970, with a key to the genera of Chirodiscidae

Summary The oriental species of the genera Olabidocarpus Lawrence, 1948, Dentocarpus Dusbabek & Cruz, 1966, Labidocarpellus Fain, 1976 and Pteropiella Fain, 1970 are revised. The species are redescribed and depicted except for a few which have been fully described recently. The total number of species known from these genera in this region is now 17. Labidocarpellus papuanus Fain, 1975 is replaced in the genus Pteropiella. The subgenus Dentocarpus (Paradentocarpus) Fain, 1976 is placed in synonymy with Labidocarpellus and the three species described in this subgenus (D. (P.) abyssinicus Fain, 1976, D. (P.) phyllodermae Fain, 1976, and D. (P.) kimberleyensis Fain & Lukoschus, 1981) are transferred to Labidocarpellus. Labidocarpellus notopteris Fain, 1976 and L. novaeguineae Fain, 1976 are now transferred to Dentocarpus. Olabidocarpus peropteryx Fain, 1972 and O. guyanensis Fain, 1972 are transferred to Labidocarpellus. A key is given to all the genera of Chirodiscidae parasitic on bats. ac]19820102     

Improved tribal delimitation of the subfamily Dictyopharinae and description of new genera and new species (Homoptera,Fulgoroidea, Dictyopharidae)

Ten new genera, five new subgenera, and five new species are described in the family Dictyopharidae. Three generic names are synonymized. A new name is proposed for the generic homonym. Dictyophara kazeruna Dlabola is transferred to the genus Callodictya Melichar. The genus Sinodictya Matsumura, with the type species Sinodictya tukana Matsumura, is redescribed. A new key to the tribes of the subfamily Dictyopharinae is given. The composition and characters of the tribes Taosini and Lappidini are revised. All the genera of the subfamily Dictyopharinae are listed according to their tribal position. New records are given for some interesting species.     

A new species of Plectognathotrema Layman, 1930 (Trematoda: Zoogonidae) from an Australian monacanthid,with a molecular assessment of the phylogenetic position of the genus

During helminthological examinations of teleost fishes of Ningaloo Reef, Western Australia, a new species of the enigmatic genus Plectognathotrema Layman, 1930 was discovered infecting the pot-bellied leatherjacket Pseudomonacanthus peroni (Hollard). The new species, Plectognathotrema kamegaii n. sp., is formally described, and the status of its four congeners is reviewed. Plectognathotrema hydrolagi Olson, Hanson & Pratt, 1970 is not recognised within the genus, as it differs greatly from its congeners in the form and arrangement of the vitellarium, testes and uterus, and in that it was described from a holocephalan. Plectognathotrema cephalopore Layman, 1930 and P. tsushimaense Kamegai, 1970 are morphologically similar, were described from the same host species and from close geographical localities and are considered synonymous. The new taxon is most similar to P. cephalopore, but differs from it in being much smaller and possessing a distinctly larger oral sucker relative to its body size. The generation of novel partial 28S ribosomal DNA sequences allowed a phylogenetic assessment of the genus and demonstrated that Plectognathotrema clearly belongs in the Zoogonidae Odhner, 1902, rather than in the Fellodistomidae Nicoll, 1909, where it is currently assigned. With the inclusion of Plectognathotrema in the Zoogonidae, there are now three zoogonid genera for which the species are restricted to monacanthid teleosts, i.e. Cephaloporus Yamaguti, 1934, Plectognathotrema and Yamagutiplectognathotrema Parukhin, 1977. Species of these genera share pronounced morphological and ecological affinities and a previously synonymised subfamily, the Cephaloporinae Yamaguti, 1934, is resurrected for them. The host specificity of these trematodes is commented upon.     

Phylogeny of split‐footed lacewings (Neuroptera,Nymphidae), with descriptions of new Cretaceous fossil species from China

A phylogeny of the lacewing family Nymphidae based on morphology and DNA sequences is presented including representatives of all living genera and selected fossil genera. Widely distributed Jurassic and Cretaceous genera gave rise to recent taxa now restricted to Australasia. Two previously defined clades (i.e. Nymphinae and Myiodactylinae) were recovered and reflect the diverging adult and larval morphology of members of these two subfamilies. From Chinese Cretaceous deposits, a new genus (Spilonymphes gen. nov.) is described with one new species, as well as new species described in the genera Baissoleon Makarkin and Sialium Westwood.     

The orchids of Timor: checklist and conservation status

A checklist of the Orchidaceae of Timor is presented, with emphasis on the eastern half of the island (East Timor), based on historical herbarium collections and recent botanical explorations. This list comprises 38 genera with 66 species, including 15 new genera and 32 new species records for this island. Moreover, four new species are described: Bulbophyllum sundaicum , Habenaria ankylocentron , Habenaria cauda‐porcelli , and Pterostylis timorensis . Of these, we consider the finding of a new species of Pterostylis to be especially noteworthy, because this species seems to be more closely related to certain Australian members of the genus than to the Malesian ones, suggesting earlier contacts of Timor with Australia. Four new synonyms are proposed: Calanthe veratrifolia var. timorensis J.J.Sm. (C. triplicata), Habenaria cornuta Span. (H. giriensis), H. grandis Benth. ex Ridl. (Peristylus goodyeroides), and H. mutica Span. (H. elongata). The best represented genus is Habenaria, with 13 species, followed by Dendrobium with four, and Bulbophyllum with three. Because of insufficient or sterile material, it was not possible to identify, or describe as new, 20 different taxa. The conservation status of the ten endemic species, plus six possible new undescribed species and two non‐endemic, but threatened, species, was assessed using the World Conservation Union (IUCN) criteria, and categories of threat were proposed. Seven endemic species are considered to be Critically Endangered and two Endangered. One of the nonendemic species is considered to be Critically Endangered, and the other Endangered. The survival of some of these species might be less insecure if an effective application of Regulation project N.2000/19 on protected areas (UNTAET/REG/2000/19) was implemented and maintained, because most of these species were collected in areas considered for protection under this Regulation. Further studies are required, however, in order to complete our knowledge of the diversity and population dynamics of this interesting part of Timor's biodiversity. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 157 , 197–215.     

Phylogeny and taxonomy of European funnel‐web spiders of the Tegenaria−Malthonica complex (Araneae: Agelenidae) based upon morphological and molecular data

The taxonomy and systematics of European house spiders, currently constituting the ill‐defined Tegenaria?Malthonica complex (including Aterigena) in the family Agelenidae, are revised. In Europe four monophyletic genera and 81 species are defined. One genus, Eratigena gen. nov. , and seven species are described as new; at species level 17 new synonyms and 20 new combinations are proposed, and the original combination of 14 species is reinstated. Five species could not be placed (incertae sedis) because of insufficient material and one taxon is regarded as ‘nomen dubium’. On the basis of a detailed morphological assessment, 88 characters were chosen for a cladistic analysis. Phylogenetically informative characters include mostly spination patterns as well as spinneret and genital structures. In addition to morphology, three gene sections [cytochrome c oxidase subunit 1 (CO1), nicotinamide adenine dinucleotide dehydrogenase subunit 1 (NADH1) 28S] were analysed. Morphological and molecular analyses were performed individually and in combination applying maximum parsimony and Bayesian tree search methods. In all resulting trees Malthonica and Tegenaria in their present composition are either polyphyletic or paraphyletic. Consequently, we redefined the two genera and erected a new genus, Eratigena gen. nov. Identification keys are provided for the European agelenid genera as well as for the European species of Tegenaria and Eratigena gen. nov. The genera and most of the constituent species are described and illustrated. The new classification has also been applied to some extra European members of the Tegenaria‐Malthonica complex resulting in additional three new synonyms, seven reversals to the original combination, and four new combinations. © 2013 The Linnean Society of London     

Paraconvexitermes acangapua (Isoptera: Termitidae,Nasutitermitinae), a new genus and new species of the so-called “small Neotropical soil-feeding nasutes” from South America

A new genus Paraconvexitermes is described, comprising Paraconvexitermes acangapua, new species, P. nigricornis (Holmgren) and P. junceus (Emerson), both previously in Convexitermes Holmgren. Now, Convexitermes comprises C. manni Emerson and C. convexifrons (Holmgren). The worker’s digestive tube of both genera along with those of Atlantitermes species allowed to get a better definition of these three genera. Illustrations on the digestive tube and mandibles of workers, soldier’s head, alate’s head and secondary reproductive female of the new genus and species are provided. The phylogenetic relationships with the other nasute genera are discussed along with the “soil feeding” concept.     

Taxonomie der gattungchiropteridium gocht (dinophyceae) im rupelium des mainzer beckens (mitteloligozän,SW-Deutschland)

Five morphotypes of the dinoflagellate cyst genusChiropteridium Gocht from Middle Oligocene sediments in the Mainz Basin (SW-Germany) are described. Two of the morphotypes are grouped with the speciesChiropteridium aspinatum and C.lobospmosum. For another morphotype the new speciesChiropteridium brevifolium is proposed.     

A SYNOPSIS OF THE GENERA AND SPECIES OF THE TRIBE THELEBOLEAE (= PSEUDOASCOBOLEAE)

Examination of genera of the Pseudoascoboleae (Ascomycetes, Discomycetes, Ascobolaceae) revealed that many were polytypic. Characters presently used to distinguish these genera are considered to be artificial and true relationships cut across accepted generic lines. Of the genera treated, Thecotheus and parts of Ascophanus, since their asci blue in iodine and their spores bear callose-pectic markings, are considered more closely related to the Pezizeae. Other genera are excluded from the Pseudoascoboleae because of other striking characters. Since the Pseudoascoboleae is shown to be an artificial grouping, it is proposed to abandon the name, using instead the tribe name Theleboleae, placed in the Pezizaceae rather than the Ascobolaceae, for all of those genera with asci that do not blue in iodine, with smooth, elliptical spores without oil guttules, and with eight-spored and multispored species. Four new genera are described: Iodophanus, for species of Ascophanus with iodine-positive asci; Coprotus, for segments of Ascophanus and Ryparobius; Caccobius, for species intermediate to Ascozonus and Thelebolus; and Trichobolus, for the setose members of Thelebolus. The species of Ryparobius not belonging to Coprotus are transferred to Thelebolus.     

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.     

STUDIES ON THE TRIBE ALLANTINI (HYM: TENTHREDINIDAE) —NEW TAXA AND RECORDS OF ALLANTINI FROM CHINA*

Abstract Filixungulia gen. nov. belonging to Allantini and three new species, Filixungulia dbo-clypea sp. nov., F. crassitarsata sp. nov., and Macremphytus crasskornis sp. nov. are described from China. A synoptic key to the genera with three cubital cells in front wing of Allantini is proposed. The genera Tritobrachia Enderlein, Macremphytus MacGillivray and Linomorpha Malaise with Tritobrachia tenuicornis Enderlein are new records from China. Linamorpha flava (Takeuchi) is a new combination transferred from Emphytus Klug.

Phylogeny of the reptilian Eimeria: are Choleoeimeria and Acroeimeria valid generic names?

Reptiles are the animals with the most described coccidian species among all vertebrates. However, the co‐evolutionary relationships in this host–parasite system have been scarcely studied. Paperna & Landsberg (South African Journal of Zoology, 24, 1989, 345) proposed the independent evolutionary origin of the Eimeria‐like species isolated from reptiles based on morphological and developmental characteristics of their oocysts. Accordingly, they suggested the reclassification of these parasites in two new genera, Choleoeimeria and Acroeimeria. The validity of the genera proposed to classify reptilian Eimeria species remained unresolved due to the lack of species genetically characterized. In this study, we included 18S rRNA gene sequences from seven Eimeria‐like species isolated from five different lizard host families. The phylogenetic analyses confirmed the independent evolutionary origin of the Eimeria‐like species infecting lizards. Within this group, most species were placed into two monophyletic clades. One of them included the species with ellipsoidal oocysts (i.e. Choleoeimeria‐like oocysts), whereas the species with more spheroidal oocysts (i.e. Acroeimeria‐like oocysts) were included in the second one. This result supports the taxonomic validity of the genera Acroeimeria and Choleoeimeria.
