All known Queensland species of the isopod family Sphaeromatidae, subfamily Sphaeromatinae (= hemibranchs), are discussed. The following new taxa are erected: Calcipila cornuta, gen. nov., sp. nov. ; Cymodoce tribullis, sp. nov. ; Cymodoce bipapilla, sp. nov. ; Paracilicaea aspera, sp. nov. ; Cilicaeopsis glebosa, sp. nov. ; Cilicaeopsis furculata, sp. nov. ; Cilicaea calcarifera, sp. nov. ; Zuzara curtispina, sp. nov. ; Zuzara digitata, sp. nov. ; and Clianella brucei, sp. nov. Exosphaeroma intermedium Baker is transferred to the genus Sphaeroma Latreille. The genus Dynoides Barnard is reviewed and its current synonymy is contested. With several new records, this brings the total number of sphaeromatid species known from Queensland to 49, 24 of which are in the subfamily Sphaeromatinae. A checklist of all sphaeromatid species occurring in Queensland waters is given. From the rest of Australia: Cymodoce tuberculata Haswell is given the replacement name Cymodoce haswelli, nom. nov. ; Cymodoce granulata Miers is made a junior synonym of Cerceis trispinosa (Haswell) (subfamily Dynameninae); Zuzara diadema Leach, Z. dicantha (Milne Edwards) and Z. Integra Haswell are made junior synonyms of Z. semipunctata Leach; Cilicaeopsis dakini Tattersall is tentatively transferred to the genus Paracilicaea Stebbing. The genera discussed are reviewed world-wide and among the non-Australian species: Exosphaeroma papillae Bayliff is transferred to the genus Sphaeroma; Sphaeroma irakiensis Ahmed is made a junior synonym of Sphaeroma annandalei annandalei Stebbing; Cymodoce richardsoniae Nobili is shown to be distinct from Cymodoce truncata Leach; Cymodoce eupyga Nobili is transferred to the genus Paracilicaea; Dynoides amblysinus Pillai, Dynoides castroi Loyola e Silva and Exosphaeroma globicaudum (Dana) are transferred to the genus Clianella Boone; Dynoides brasiliensis (Loyola e Silva; and Sphaeroma savignn Milne Edwards sensu Dana, 1853 are declared to be conspecific with Clianella castroi. The name Sorrentosphaera Verhoeff is made a junior synonym of Dynamene Leach (subfamily Dynameninae.  相似文献

Hieracium pallidum subsp. aetnense Gottschl., Raimondo & Di Grist. is described and illustrated. H.pallidum is considered as an intermediate species between H. schmidtii and H. racemosum (“schmidtii>racemosum”) and is placed in H. sect. Grovesiana. By consequence, H.lanudae Gottschl. is transferred to H. pallidum as H. pallidum subsp. lanudae (Gottschl.) Gottschl., Raimondo & Di Grist. A key for the three recognised subspecies of H. pallidum is provided.  相似文献

Abstract

Fissidens firmus is revised, described, illustrated and a distribution is provided. It is compared to Fissidens hollianus, Fissidens pseudofirmus, Fissidens sedgwickii and Fissidens touwii. It is provisionally distinguished from F. firmus sensu auct. Fissidens multiflorus is reduced to F. hollianus. Lectotypes are designated for Fissidens multiflorus and Fissidens giesenhagenii. The collection that was reported from India as F. firmus appears to be F. hollianus. Thus, the present Western Ghats collection is effectively the first Indian record of F. firmus.  相似文献

Four Phaeosphaeria species on bamboos are reported. Leptosphaeria lelebae on culms of Bambusa multiplex is synonymized with P. oryzae. A Phaeosphaeria sp. on leaves of Sasa kurilensis is noted to have some similarities to Leptosphaeria sasae. Cultural characteristics of P. brevispora collected from culms of Sasa sp. are first recorded. Phaeosphaeria bambusae on leaves of Pleioblastus simoni is redescribed. In addition, the history of taxonomic studies on bambusicolous fungi in Japan is briefly reviewed.  相似文献

The asymptotic quasi‐likelihood method is considered for the model yt = ft(θ) + Mt, t = 0,1, …,T where ftθ) is a linear predictable process of the parameter of interest θ, Mt is a martingale difference, and the nature of E(Mt2 | ℱt–1) is unknown. This paper is concerned with the limiting distribution of the asymptotic quasi‐score function of such a model. Confidence intervals and hypothesis testing of θ is derived from the limiting distribution. Comparison is made between the estimates obtained through this method and those obtained through the least squares method.  相似文献

The implication of state space structure on the existence of a repeatable experimentE designed to determine if a statesL has propertyP or notP is investigated. It is shown that if a state spaceL is connected, then no experimentE is repeatable. This formalism is used to demonstrate that if a propertyP has an associated set of points inL which is dense with dense complement inL, then there exists no repeatable experimentE which can be used to test whethers has propertyP or notP. Other consequences of this formalization are discussed.  相似文献

FLOWERING LOCUS M (FLM) is a MADS-domain gene that acts as an inhibitor of flowering in Arabidopsis. Here we describe the genetic interaction of FLM with genes in the photoperiod and autonomous flowering pathways. Although the sequence of FLM is most similar to that of FLC, FLM and FLC interact with different flowering pathways. It has been previously shown that flc lesions suppress the late-flowering phenotype of FRI-containing lines and autonomous-pathway mutants. However, flm lesions suppress the late-flowering phenotype of photoperiod-pathway mutants but not that of FRI-containing lines or autonomous-pathway mutants. Another MADS-domain flowering repressor with a mutant phenotype similar to FLM is SVP. The late-flowering phenotype of FLM over-expression is suppressed by the svp mutation, and an svp flm double mutant behaves like the single mutants. Thus FLM and SVP are in the same flowering pathway which interacts with the photoperiod pathway.

Macrolycus is a genus of net‐winged beetles with 69 species distributed in the eastern Palearctic and northernmost part of the Oriental region. The first molecular phylogeny of Macrolycus was produced using an rrnL + tRNA‐Leu + nad1 mtDNA fragment. The major lineages and species limits were identified with morphology and molecular data. We propose that Cerceros is a subgenus of Macrolycus to enable identification of all adult specimens in the genus without DNA sequencing. Two species groups are proposed in Macrolycus s. str. and six in Cerceros. Additionally, twelve Macrolycus species are newly described from China: M. aquilinus, M. baihualingensis, M. bicolor, M. guangxiensis, M. jianfenglingensis, M. kuatunensis, M. lizipingensis, M. parvus, M. phoeniceus, M. rhodoneurus, M. rosaceus and M. sichuanensis. Macrolycus holzschuhi is proposed to be a junior subjective synonym of M. jeanvoinei. The highest diversity of Macrolycus is found in southern China. The species from the main islands of Japan are placed in two species groups: M. excellens is a sister to remaining species of the M. murzini group and the M. flabellatus group is a monophylum of closely related species in a sister position to the M. bicolor group.  相似文献

Summary  Twenty-eight species of heterobasidiomycetes (phylum Basidiomycota) belonging to the orders Auriculariales, Dacrymycetales, Exidiales, Platygloeales, Sebacinales, Septobasidiales and Tremellales from Belize are described or reported. Endoperplexa phlebioides, Heterochaete pentadelphai and Sebacina pileata are described as new. The genus Aphelariopsis is considered a possible synonym of Septobasidium and the new combination Septobasidium kupemontis is proposed. The new combination Endoperplexa obscura is also proposed.  相似文献

The genus Microstictia is characterized, its species are diagnosed and keyed; their distribution and collecting period summarized; and their taxonomic status discussed. Photographs of selected important characters are provided. Two new species are described, Microstictia pimensis from Arizona (in the rufescens species group) and M. eos from Florida (in the femorata species group). This is the first unambiguous record of Microstictia from the eastern USA. Based on this finding, M. femorata may actually have originated from Florida, which is frequently questioned. Microstictia minutula (described in Monedula), currently misinterpreted, is a valid name for M. texensis Gillaspy, new synonym. This new synonymy is largely based on female colour characters, whose significance is discussed. The species hitherto known as M. minutula is actually M. exigua (W. Fox), with M. divergens (J. Parker) as a new junior synonym.  相似文献

Summary T(Y;2) translocations were used to cytologically localise the wingless locus of Drosophila melanogaster. We found that an existing T(Y;2), which is an insertion of a segment of 2L into the Y chromosome, has wg + within this insert. This Y chromosome was used to generate an attached XY chromosome containing wg +. The mutation claret-nondisjunctional (ca nd) was used to induce the loss of this XY chromosome and thus generate gynandromorphs with wg 1/wg 1 male tissue and wg +/wg 1/wg 1 female tissue. Analysis of these gynanders demonstrated that a genotypically wingless mutant hemithorax is usually also phenotypically mutant in these half body mosaics; thus wg 1 is discautonomous. This observation is of interest as it is known that wg is not cell autonomous.  相似文献

The floral vasculature in three allied genera,Plagiorhegma, Jeffersoria andAchyls is investigated, and the results are compared with those ofEpimedium andVancouveria which are related closely toPlagiorhegma andJeffersonia. The vasculature in the receptacle ofPlagiorhegma andJeffersonia is similar, but that ofAchlys is much simpler. Slightly different trace patterns are observed in the sepals ofPlagiorhegma andJeffersonia. InJeffersonia, the 3-trace condition leaving 2 or 3 gaps is most frequently observed, but inPlagiorhegma traces of a double nature leaving a single gap are more frequent. The traces to the innermost sepals, petals and stamens are usually of a double nature leaving a single gap in both genera. Regular division and fusion are not observed in the receptacular stele. The vascular differentiation between sepals and petals is more advanced inPlagiorhegma andJeffersonia than inEpimedium andVancouveria. InAchlys, the traces are all staminal and single throughout their course. Two parts recognized in the pistils ofPlagiorhegma, Jeffersonia andAchlys are traversed by independent vasculature. The comparisons of pistil morphology including vasculature ofPlagiorhegma, Jeffersonia, Achlys, Epimedium andVancouveria lead to the interpretation that the pistils are based on the same morphological plan. The probable evolutionary trend in pistil is then suggested in these five genera.  相似文献

Abstract

A new species of Carabus (Lamprostus) from the province of Gilan, Iran, is described and illustrated: Carabus (Lamprostus) staveni sp. nov., Carabus (Pachystus) rechingerae Mandl, 1972, is considered a junior synonym of Carabus (Lamprostus) calleyi nigrinus Motschulsky, 1865. The specific status of Carabus (Sphodristocarabus) korgei Heinz, 1970, is restored (stat. rev.) and Carabus separatus delirensis Deuve, 2000, is considered to be a junior synonym of it. Carabus (Megodontus) stroganowi javahardensis Deuve, 2000, is considered to be a synonym of Carabus (Megodontus) heinrichi Mandl, 1966; both taxa are from the same type locality.  相似文献

An update on the taxonomy and geographic distribution of the genus Thymus in Sicily is given. This study is based on literature, herbarium and field investigations. In total, five taxa belonging to Thymus sect. Serpyllum (Th.richardii subsp. nitidus, Th.longicaulis and Th.praecox subsp. parvulus) and Th. sect. Hyphodromi (Th.spinulosus and Th.paronychioides) occur in Sicily. For each one, information about taxonomy, habitat, phenology, chromosome number and distribution are provided. Furthermore, the name Thymus pedicillatus Lojac. is here typified. Finally, an analytical key for the identification of the studied taxa is proposed.  相似文献

The aim of this study is to provide new syntaxa for the Italian vegetation checklist. For the class Rhamno–Prunetea which includes the class Paliuretea the new alliance Rhamno saxatilis–Paliurion spinae-christi is described, that is included in the order Paliuretalia spinae-christi with a central-western Mediterranean and sub-Mediterranean distribution. Otherwise, the more thermophilous Paliurus spina-christi vegetation is included in the new suballiance named as Oleo sylvestris–Paliurenion spinae-christi within the alliance Oleo–Ceratonion of the class Quercetea ilicis. For the class Trifolio–Geranietea medii, a new alliance named Hyperico calabricae–Asphodelion macrocarpi is proposed here.  相似文献

The aphid genus Blackmania gen. nov. is described. In the genus, B. eastopi sp. nov. associated with Polygonum equisetiforme (Polygonaceae) from Israel and Cyprus is described and illustrated. Morphologically, the new genus is similar to the genus Acaudella in respect to the lack of a cauda. Acaudella puchovi, associated with Atraphaxis caucasica (=A. buxifolia) and A. spinosa (Polygonaceae) from Uzbekistan and Israel, is re‐described and the apterous viviparous female is figured for the first time. The lectotype and paralectotypes of A. puchovi are also designated. An identification key to known species of the tribe Macrosiphini without cauda is provided. The morphological separation of B. eastopi gen. nov., sp. nov. from A. puchovi is visualized using principal component analysis.  相似文献

The genus Neoerysiphe belongs to the tribe Golovinomyceteae of the Erysiphaceae together with the genera Arthrocladiella and Golovinomyces. This is a relatively small genus, comprising only six species, and having ca 300 species from six plant families as hosts. To investigate the molecular phylogeny and evolution of the genus, we determined the nucleotide sequences of the rDNA ITS regions and the divergent domains D1 and D2 of the 28S rDNA. The 30 ITS sequences from Neoerysiphe are divided into three monophyletic groups that are represented by their host families. Groups 1 and 3 consist of N. galeopsidis from Lamiaceae and N. galii from Rubiaceae, respectively, and the genetic diversity within each group is extremely low. Group 2 is represented by N. cumminsiana from Asteraceae. This group also includes Oidium baccharidis, O. maquii, and Oidium spp. from Galinsoga (Asteraceae) and Aloysia (Verbenaceae), and is further divided into four subgroups. N. galeopsidis is distributed worldwide, but is especially common in western Eurasia from Central Asia to Europe. N. galii is also common in western Eurasia. In contrast, the specimens of group 2 were all collected in the New World, except for one specimen that was collected in Japan; this may indicate a close relationship of group 2 with the New World. Molecular clock calibration demonstrated that Neoerysiphe split from other genera of the Erysiphaceae ca 35–45 M years ago (Mya), and that the three groups of Neoerysiphe diverged between 10 and 15 Mya, in the Miocene. Aloysia citriodora is a new host for the Erysiphaceae and the fungus on this plant is described as O. aloysiae sp. nov.  相似文献
