The Joint Occurrence of Chloroxanthones in Southern Hemisphere Lecanora Species (Ascomycotina; Lecanoraceae)

Four species belonging to the Lecanora subfusca group (Lecanoraceae, lichenized Ascomycotina) and containing the 2,5,7-trichloro-3-O-methylnorlichexanthone chemosyndrome are described: L. elixii Lumbsch, L. epibryon Ach., L. mayrhoferi Lumbsch spec. nov. and L. parmelinoides Lumbsch spec. nov. The species, which are interpreted as being closely related, can be distinguished by a combination of subtle morphological and anatomical characters.     

SYSTEMATICS OF TRIPSACUM DACTYLOIDES (GRAMINEAE)

Tripsacum dactyloides (L.) L. extends across the range of this genus from about 42°N to 24°S latitude in the New World. It is recognized to include T. dactyloides var. dactyloides (North America), var. meridonale deWet et Timothy (South America), var. hispidum (Hitchc.) deWet et Harlan comb. nov. (Mesoamerica) and var. mexicanum deWet et Harlan var. nov. (Mesoamericana). The genus is divided into sections Tripsacum and Fasciculatum. Mesoamerican members of section Tripsacum are classified into T. bravum Gray, T. dactyloides (L.) L., T. intermedium deWet et Harlan spec, nov., T. latifolium Hitchc., T. manisuroides deWet et Harlan spec. nov. and T. zopilotense Hern,*** et Randolph. A key to the species of section Tripsacum is presented.     

A SYSTEMATIC REVISION OF PHYLLANTHUS SUBSECTION URINARIA (EUPHORBIACEAE)

The examination of several taxa from various tropical regions of the world, previously classified as Phyllanthus urinaria L., indicates that they do not belong to a single species. On the basis of morphology, cytology, genetics, and biometry, a new classification is presented in which the collective species P. urinaria, or “urinaria complex,” is elevated to the subsection level: Phyllanthus subsection Urinaria. Within the subsection, two subgroups may be recognized on the basis of seed coat ornamentation. Each of these lines is represented by two species which differ from each other in chromosome number: P. embergeri nov. spec. (2n = 100) and P. nozeranii nov. spec. (2n = 50) in the “spiraled” line, P. hookeri Muell. Arg. (2n = 100) and P. urinaria L. (2n = 50) in the “radiated” line. In the latter species, which has undergone diversification, two subspecies may be distinguished: P. urinaria urinaria and P. urinaria nudicarpus subspec. nova.

Morphological description of three marine ciliates (Ciliophora, Scuticociliatia), with establishment of a new genus and two new species

Three marine scuticociliates, Falcicyclidium fangi nov. gen., nov. spec., Falcicyclidium atractodes nov. spec., and Cristigera media Kahl, 1928 were investigated using live observation and silver impregnation methods. The genus Falcicyclidium is distinguished by the combination of: (i) dorsoventrally flattened body, (ii) hook-like (falciform) paroral membrane, (iii) anterior end of paroral membrane posterior to anterior end of membranelle 1, and (iv) multiple caudal cilia. Falcicyclidium fangi nov. spec., the type of the new genus, can be recognized by the combination of its large size, extremely dorsoventrally flattened (3:1) body, consistently 10 somatic kineties, and the broad, elongate buccal area occupying 60% of the body length. Falcicyclidium atractodes nov. spec. is mainly characterized by a unique spine projecting from both the anterior and posterior end. The uncommon form, Cristigera media is redescribed based on the population from Qingdao, the statistic data and additional features, especially the morphology of the living cells, are documented.     

Notes on the soil ciliate biota (Protozoa, Ciliophora) from the Shimba Hills in Kenya (Africa): diversity and description of three new genera and ten new species

A very diverse ciliate community was found in nine soil samples from the Shimba Hills Nature Reserve in Kenya, equatorial Africa. The ciliates, respectively, their resting cysts, were re-activated from air-dried samples using the non-flooded Petri dish method. Species were determined from life and by silver impregnation. 34 (27%) of the 125 taxa identified had not yet been described in 1985, when the samples were collected and investigated. The richest samples, each containing 59 species, were those from a deciduous primary forest and a young secondary pine forest. The most remarkable species discovered in the Shimba Hills were Krassniggia auxiliaris, Bresslauides terricola, Gigantothrix herzogi, and Afrothrix darbyshirei. They are flagships with a very distinct morphology and easy to recognise due to their extraordinarily large body size. Krassniggia auxiliaris occurs also in Australia and probably has a restricted Gondwanan distribution, like some other ciliates. Bresslauides terricola was later found in soils from all main biogeographical regions, except for Antarctica. Gigantothrix herzogi and Afrothrix darbyshirei are still unique to the Shimba Hills. The following taxa are described in detail: Sikorops woronowiczae nov. gen., nov. spec., Arcuospathidium multinucleatum nov. spec., Dileptus similis Foissner, 1995, Plagiocampa bitricha nov. spec., Drepanomonas exigua exigua Penard, 1922, D. exigua bidentata nov. sspec., Parafurgasonia protectissima (Penard, 1922) nov. comb., P. terricola nov. spec., Brachyosoma brachypoda mucosa nov. sspec., Gigantothrix herzogi nov. gen., nov. spec., Afrothrix darbyshirei nov. gen., nov. spec., Oxytricha africana nov. spec., and O. elegans nov. spec.

Pleospora drammondii spec. nov. and its anamorph Stemphylium drammondii spec. nov. The causal organism of a leaf spot disease on Phlox drummondii is described as Pleospora drummondii spec. nov. and its anamorph Stempbylium drummondii spec, nov. — in contrast to earlier reports from the USA, in which the fungus was identified as S. botryosum.     

Morphology and molecular phylogeny of two new soil ciliates,Hemiurosomoida warreni nov. spec. and Hemiurosoma clampi nov. spec. (Ciliophora,Hypotrichia) from Tibet

Two novel hypotrichous ciliates, Hemiurosomoida warreni nov. spec. and Hemiurosoma clampi nov. spec., isolated from soil in the Lhalu Wetland and Motuo Virgin Forest in Tibet, respectively, were investigated using live observation and protargol staining. Hemiurosomoida warreni nov. spec. strongly resembles the type species H. longa but can be distinguished by its body size in vivo (110–145 × 30–40 μm vs. 50–100 × 18–40 μm), number of adoral membranelles (25–38 vs. 15–22), and numbers of right (29–39 vs. 14–23) and left (26–35 vs. 13–23) marginal cirri, transverse cirri (3 vs. 4 or 5) and macronuclear nodules (4–8 vs. 2). Hemiurosoma clampi nov. spec. is characterized by its vermiform body shape, colourless cortical granules distributed in irregular rows, two macronuclear nodules, three frontal cirri, one buccal cirrus, four frontoventral cirri ranged in a line, two transverse cirri, lacking postoral ventral and pretransverse ventral cirri, and marginal rows that are not posteriorly confluent. Phylogenetic analyses based on SSU rDNA gene sequences suggest that Hemiurosomoida is not monophyletic. A close relationship is revealed between Hemiurosomoida warreni nov. spec., Parakahilella macrostoma, Hemiurosoma clampi nov. spec., and the type species Hemiurosoma terricola. As expected, all these species are classified within the “non-oxytrichid Dorsomarginalia”.     

The Psyllids (Homoptera: Psylloida) of Alaska

A key is provided for the identification of the thirty-eight psyllid species recorded from Alaska. Additional notes on host plant and distribution are given for each species. The species are: Aphalara manitobaensis Cald.,A.nigra Cald., Craspedolepta alaskensis (Ash.), C.nebulosa (Zett.) ssp. kincaidi (Ash.), C. schwarzi (Ash.), C.subpunctata (Förster), Psylla alaskensis Ash., P.betulaenanae Oss., P.breviata Patch, P.fibulata Crawf., P.floccosa Patch, P.galeaformis Patch, P.haliaeeti sp.nov., P.hamata Tuthill, P.highwoodensis sp.nov., P.jenseni sp.nov., P.kananaskensis Hod., P.ledi Flor., P.longiforceps sp.nov., P.minor Crawf., P.macleani sp.nov., P.myrtilli Wag. ssp. canadensis Hod., P.palmeni Löw, P.phlebophyllae sp.nov., P.rara Tuthill, P.rufipennis sp.nov., P.sinuata Crawf., P.striata Patch, P.stricklandi Crawf., P.toolikensis sp.nov., P.zaecevi Sulc, Trioza albifrons Crawf., Trioza artica sp.nov., T.atkasookensis sp.nov., T.incerta Tuthill, T.salicivora Reut. (=T.maura auctt. N.Amer.), T.stylifera Patch, Trioza sp.nov. (undescribed). All the newly described species were collected on Salix. The Alaskan fauna is made up of four major components: 1, true Arctic species; 2, Arctic/subarctic species; 3, subarctic/alpine species; 4, northern forest zone species. Eight of the Alaskan psyllids exhibit an holarctic distribution and there is a strong faunal affinity with similar areas in northern Scandinavia: the same four genera recur throughout the northern holarctic. There is strong circumstantial evidence that certain psyllid species are parthogenetic over part of their range, particularly in arctic/alpine situations.     

Two new marine pleurostomatid ciliates from China,Amphileptus gui nov. spec. and Amphileptus yuianus nov. spec. (Ciliophora,Pleurostomatida)

The morphology and infraciliature of two pleurostomatid ciliates, Amphileptus gui nov. spec. and A. yuianus nov. spec., collected from mariculture ponds near Qingdao (Tsingtao), China, were investigated using living observations and the protargol impregnation method. These new species are distinguished from their congeners by a combination of characters including their marine habitat and the presence of an apical group of densely packed extrusomes. Amphileptus gui nov. spec. differs from A. yuianus nov. spec. mainly in the number of contractile vacuoles (3–7 vs. 1), the shape of extrusomes (thin bar-like vs. clavate), and the number of left and right somatic kineties (7–11 and 37–50 vs. 4 and 18–22).

Morphology and Phylogeny of Three Trachelocercid Ciliates,with Description of a New Species,Trachelocerca orientalis spec. nov. (Ciliophora,Karyorelictea)

Three trachelocercid ciliates, Trachelocerca orientalis spec. nov., Prototrachelocerca fasciolata (Sauerbrey, 1928) Foissner, 1996 and Tracheloraphis huangi Xu et al., 2011, isolated from marine coastal habitats at Qingdao, China, were taxonomically studied using observation in vivo and silver staining methods. The new species T. orientalis spec. nov. can be recognized by the combination of its size (600–1,200 μm in vivo), 15–21 somatic kineties and about 13 groups of macronuclear nodules forming a strand and the colorless globular cortical granules. Together with the sequence data of the small subunit ribosomal RNA (SSU rRNA) gene, the information of a new isolate of P. fasciolata and three populations of T. huangi is also documented based on the present work. According to the molecular data, the phylogeny of three species is estimated and the analyses show that they are all found within the trachelocercid assemblage though T. huangi does not cluster with its congeners but with Trachelocerca species. Nonetheless, the monophyly of Trachelocerca is not rejected by the approximately unbiased test (p = 0.345 > 0.05), while that of Tracheloraphis is not confirmed (p = 0.0002 < 0.05).     

Molecular Phylogeny and Taxonomy of a New Freshwater Hymenostomatid from Northeastern China,with the Establishment of a New Genus Anteglaucoma gen. n. (Protista,Ciliophora, Oligohymenophorea)

The morphology, infraciliature and SSU rDNA sequence of a new freshwater hymenostomatid ciliate, Anteglaucoma harbinensis gen. nov., spec. nov., collected from a farmland pond in Harbin, China, were investigated. The new genus Anteglaucoma is characterized as follows: small to medium‐sized Glaucomidae with oral apparatus in anterior one‐third of cell; paroral membrane composed of almost longitudinally arranged dikinetids; three adoral membranelles nearly equal in length and arranged almost longitudinally in parallel; silverline pattern tetrahymenid. The improved diagnosis of family Glaucomidae Corliss 1971 is provided based on the previous and present work. The type species Anteglaucoma harbinensis spec. nov. is defined by having 32–35 somatic kineties; four or five postoral kineties; membranelle 1 and membranelle 2 having five or six kinetosomal rows, membranelle 3 having three kinetosomal rows; single macronuclear nodule; contractile vacuole on average 15% from posterior body end; locomotion characterized by crawling with a rather hectic jerking motion; freshwater habitat. Phylogenetic analyses show that Anteglaucoma clusters in the family Glaucomidae and groups with the genera Glaucoma. The molecular and morphological data indicate that Glaucomidae is related to the family Bromeliophryidae in the phylogenetic trees.
