Abstract

Morphological and ecological observations on four fleshy crustose algae collected in the eulittoral and upper sublittoral zone of the Island of Gorgona: Myrionema liechtenstenii Hauck, Hildenbrandia canariensis B?rgesen, Peyssonnelia armorica (P. et H. Crouan) Weber-van Bosse in B?rgesen and Cruoria cruoriaeformis (P. et H. Crouan) Denizot are reported. For each species, information on some aspects of their ecology, geographical distribution and notes on their vegetative and reproductive morphology are given.  相似文献

The spider genus Metabus (Tetragnathidae) previously included nine species: the type M. gravidus O. P.-Cambridge, 1899 – junior synonym of Leucauge ocellata (Keyserling) – from Central America and eight species from Chile. In this paper, the classification of the Metabus species-complex is revised, and two new genera, with three new species and five new combinations, are described. Allende gen. nov. is created for four Chilean species not congeneric with the type of Metabus : the type A. puyehuensis sp. nov. , A. patagiatus (Simon) comb. nov. , A. nigrohumeralis (F. O. P.-Cambridge) comb. nov. and A. longipes (Nicolet) comb. nov. Further additions to the Chilean fauna are under the new genus Mollemeta gen. nov. – created for M. edwardsi (Simon) comb. nov. – and three new species of Chrysometa : C. acinosa sp. nov. , C. levii sp. nov. and C. maitae sp. nov. Metabus now includes four species: M. ocellatus (Keyserling) comb. nov. , M. debilis (O. P.-Cambridge) comb. nov. , M. ebanoverde sp. nov. and M. conacyt sp. nov. All of these species were included in a phylogenetic analysis of 38 tetragnathid and 12 orbicularian outgroup terminals scored for 105 morphological and behavioural characters. The results suggest that Metabus as previously circumscribed is polyphyletic. The phylogenetic relationships within tetragnathids are briefly discussed. © 2007 The Linnean Society of London, Zoological Journal of the Linnean Society , 2007, 151 , 285–335.  相似文献

Plotococcus Miller & Denno is synonymized with Leptococcus Reyne (Coccoidea: Pseudococcidae). The genus is redescribed and the adult female of the type species, L. metroxyli Reyne, is redescribed and illustrated. All species hitherto included in Plotococcus are transferred to Leptococcus as L. capixaba (Kondo) comb. nov., L. eugeniae (Miller & Denno) comb. nov., L. hambletoni (Kondo) comb. nov., L. minutus (Hempel) comb. nov., and L. neotropicus (Williams & Granara de Willink) comb. nov. A new species of Leptococcus, L. rodmani Kondo sp. n., from leaves of Guarea guidonia (Meliaceae) from Colombia, is described and illustrated based on the adult female. A revised key to adult females of all species in the genus is provided.  相似文献

Holococcolithophorids, pyrmnesiophytes having only one type of calcareous element in their coccoliths, are delicate and not commonly recorded in recent and fossil marine floras. There are few records of these organisms from the Indian Ocean and 26 species from there are included in this report. Although the group, generally assigned to a single family, the Calyptrosphaeraceae, may contain species that are part of the life history of heterococcolith-bearing cells in other stages, so little is known of this aspect of their biology that one must continue, at the present time, to treat them as independent taxonomic entities. A key is provided for the known holococcolithophorid genera. A new genus, Gliscolithus, and three new species, Gliscolithus amitakarenae, Calyptrosphaera heimdalae, and Helladosphaera pienaarii are described. The following new combinations are proposed: Calyptrolithina fragaria (Kamptner) comb. nov., Calyptrolithina gaarderae (Borsetti et Cati) comb. nov., Calyptrolithina isselii (Borsetti et Cati) comb. nov., Calyptrolithina lafourcadii (Lecal) comb. nov., Calyptrolithina magnaghii (Borsetti et Cati) comb. nov., Calyptrolithina multipora (Gaarder) comb. nov., Calyptrolithina porritectum (Heimdal) comb. nov., Calyptrolithina wettsteinii (Kamptner) comb. nov., Calyptrolithophora catillifera (Kamptner) comb. nov., Calyptrolithophora galea (Lecal-Schlauder) comb. nov., Dactylethra pirus (Kamptner) comb. nov., Helladosphaera arethusae (Kamptner) comb. nov., Helladosphaera gracilis (Kamptner) comb. nov., Homozygosphaera strigilis (Gaarder) comb. nov. and Syracolithus schilleri (Kamptner) comb. nov. The new combination in the genus Dactylethra Gartner for the first time brings an extant species into this genus that formerly contained only fossil species. It is pointed out that the enlarged zygoliths in stomatal areas of Corisphaera and the helladoliths in stomatal regions of Helladosphaera have intergrading types and are not distinctive enough characteristics to separate these genera.  相似文献

Summary A new lernaeopodid copepod, Sparidicola papilliferens n.g., n. sp., is described from Acanthopagrus latus (Pisces: Teleostei) taken in Kuwait. This species is designated as a type of its genus, to which is transferred a second species, originally described as Brachiella lithognathae Kensley & Grindley, 1973, renamed Sparidicola lithognathae (Kensley & Grindley 1973) n. comb. A new name, Neobrachiella pillaii nom. nov., is proposed for Brachiella indica Pillai, 1968. The original name is preoccupied by Brachiella indica Tripathi, 1962, which is also transferred to the genus Neobrachiella Kabata, 1979, as N. indica (Tripathi, 1962) n. comb.  相似文献

The genus Parapsylla (Homoptera: Psylloidea) is redescribed and placed in the Diaphorininae of the Family Aphalaridae. Its relationships within this subfamily are discussed. The genus Agmapsylla syn. nov. is placed into the synonymy of Parapsylla , and Pennavena syn. nov. and Eudiaphorina syn. nov. are placed into the synonymy of Diaphorina. The eight known species of Parapsylla are distributed in southern Africa and upland areas of East Africa. Host plant relationships are not clearly established but the genus appears to be associated with species of Maytenus (Celastraceae), Olinia (Oliniaceae) and possibly Olea (Oleaceae) and Syzygium (Myrtaceae). Parapsylla relicta syn. nov, and A. aureus syn. nov. are placed into the synonymy of Arytaina capensis. Parapsylla capensis comb. nov. is transferred from Arytaina, Parapsylla valens comb. nov. is transferred from Diaphorina , and the following new species are described: P. angolensis sp. nov., P. eafra sp. nov., P. huila sp. nov., P. marginipennis sp. nov., P. rufa sp. nov. and P. theroni sp. nov.  相似文献

Type material of Navicula kotschyi was studied, and this species was transferred to Dorofeyukea gen. nov. as D. kotschyi comb. nov. Dorofeyukea was described on the basis of DNA sequence and morphological data. Additional species assigned to this genus that were previously included in Navicula include: D. ancisa comb. nov., D. grimmei comb. nov., D. ivatoensis comb. nov., D. orangiana comb. nov., D. rostellata comb. nov. & stat. nov., D. savannahiana comb. nov., D. tenuipunctata comb. nov., and D. texana comb. nov. All Dorofeyukea species share the same morphological features, including having a narrow stauroid fascia surrounded by 1–3 irregularly shortened striae, uniseriate, and weakly radiate striae, circular, or rectangular puncta in the striae that are covered internally by dome‐shaped hymenes, presence of a pseudoseptum at each apex and absence of septa. Partial DNA sequences of SSU and rbcL loci show Dorofeuykae belongs to the clade of stauroneioid diatoms together with Stauroneis, Prestauroneis, Craticula, Karayevia, Madinithidium, Fistulifera, Parlibellus, and, possibly, Schizostauron. A new species from the monoraphid genus Madinithidium, M. vietnamica sp. nov., was described based on valve and chloroplast morphology as well as DNA sequence data.  相似文献

Segregating Pterocladiella from Pterocladia stimulated new taxonomic studies of the species originally assigned to Pterocladia. A total of 28 species are ascribed to the genus, one of them with doubts. Thirteen of the 27 names are synonyms. Three of the remaining 14 species belong with Gelidium, including G. americanum, G. mcnabbianum (Dawson) comb. nov. and G. musciformis. Seven other species belong with Pterocladiella, including P. bartlettii (Taylor) comb. nov., P. bulbosa, P. caerulescens, P. caespitosa (Kylin) comb. nov., P. caloglossoides (Howe) comb. nov., P. capillacea and P. melanoidea. Two species are retained in Pterocladia, the type P. lucida and P. rectangularis. Two others, P. heteroplatos and P. media are placed in incertae sedis as additional studies of fertile materials are needed to determine their generic status. The genus Pterocladia now appears to include two large-sized species restricted to Australia-New Zealand. Pterocladiella has 8 small-sized species (including P. minima), mainly inhabiting tropical and subtropical waters. Future research documenting sexual reproduction in Gelidiella and solving the presently recognized heterogeneity in Gelidium will help to trace the relationships between Pterocladiella and these two genera. This revised version was published online in June 2006 with corrections to the Cover Date.  相似文献

Hybridization experiments were carried out between DNAs from more than 70 strains of Campylobacter spp. and related taxa and either 3H-labeled 23S rRNAs from reference strains belonging to Campylobacter fetus, Campylobacter concisus, Campylobacter sputorum, Campylobacter coli, and Campylobacter nitrofigilis, an unnamed Campylobacter sp. strain, and a Wolinella succinogenes strain or 3H- or 14C-labeled 23S rRNAs from 13 gram-negative reference strains. An immunotyping analysis of 130 antigens versus 34 antisera of campylobacters and related taxa was also performed. We found that all of the named campylobacters and related taxa belong to the same phylogenetic group, which we name rRNA superfamily VI and which is far removed from the gram-negative bacteria allocated to the five rRNA superfamilies sensu De Ley. There is a high degree of heterogeneity within this rRNA superfamily. Organisms belonging to rRNA superfamily VI should be reclassified in several genera. We propose that the emended genus Campylobacter should be limited to Campylobacter fetus, Campylobacter hyointestinalis, Campylobacter concisus, Campylobacter mucosalis, Campylobacter sputorum, Campylobacter jejuni, Campylobacter coli, Campylobacter lari, and "Campylobacter upsaliensis." Wolinella curva and Wolinella recta are transferred to the genus Campylobacter as Campylobacter curvus comb. nov. and Campylobacter rectus comb. nov., respectively. Bacteroides gracilis and Bacteroides ureolyticus are generically misnamed and are closely related to the genus Campylobacter. Campylobacter nitrofigilis, Campylobacter cryaerophila, and an unnamed Campylobacter sp. strain constitute a new genus, for which the name Arcobacter is proposed; this genus contains two species, Arcobacter nitrofigilis comb. nov. (type species) and Arcobacter cryaerophilus comb. nov. Wolinella succinogenes so far is the only species of the genus Wolinella. The genus Helicobacter is also emended; Campylobacter cinaedi and Campylobacter fennelliae are included in this genus as Helicobacter cinaedi comb. nov. and Helicobacter fennelliae comb. nov., respectively. The genus "Flexispira," with "Flexispira rappini" as the only species, is closely related to the genus Helicobacter. The free-living, sulfur-reducing campylobacters do not belong to any of these genera; they probably constitute a distinct genus within rRNA superfamily VI.  相似文献

The lichen genus Protopannaria is defined as different from Pannaria, being a bipolar taxon with three (of four) species in the subantarctic region: P. austro-orcadensis (Øvst.) comb. nov. in the western part and P. alcicornis P.M. Jørg. & R.S. Poulsen sp. nov. as well as P. azorellae P.M. Jørg. & R.S. Poulsen sp. nov. in the eastern one (Kerguelen), showing the greatest diversity there.  相似文献

The subfamily Protoscelinae from the Middle to Late Jurassic of Karatau is transferred from the family Chrysomelidae to the family Anthribidae. The genus Protoscelis, comprising five species, is reviewed. Males and females of the genus are described and keys to the identification of male and female specimens are provided. The new species P. medvedevi sp. nov. is described. The generic names Cerambyomima Medvedev, 1968, Pseudomegamerus Medvedev, 1968 and Protosceloides Medvedev, 1968 are synonymized under Protoscelis Medvedev, 1968, and the species Pseudomegamerus grandis Medvedev, 1968 is synonymized under Cerambyomima longicornis Medvedev, 1968. The new combinations Protoscelis longicornis (Medvedev, 1968) comb. nov. and P. nitidicornis (Medvedev, 1968) comb. nov. are established.  相似文献

The green algae genus Caulerpa is coenocytic, and the thallus consists of only one cell with many nuclei. It is widely distributed in the tropical seas. In the Southeast Asian waters, there are at least ten known species. Three species, particularly Caulerpa racemosa var. clavifera f. macrophysa (Kützing) Weber-van Bosse, C. racemosa var. laetevirens (Montagne) Weber-van Bosse, and Caulerpa lentillifera J. Agardh are widely consumed. The proximate analysis and secondary metabolite composition of these three species were determined to describe their lipid and nutritional values. Glycolipids and phospholipids were the major lipid classes, with significant levels of triacylglycerol. Polyunsaturated fatty acids (PUFA) were the major fatty acids of all the three species. Typical n-3 and n-6 PUFA such as 18:3n-3, 18:4n-3, 20:5n-3, 18;2n-6, and 20:4n-6 were found in significant amount in all these three species. All three species contained a red-pigmented secondary metabolite determined as caulerpin. All three extracts exhibited potent antimicrobial activity against human food pathogenic bacteria and anti-inflammatory activity against the murine macrophage cell line, RAW 264.7.  相似文献

A multigene phylogeny using COI‐5P (mitochondrial cytochrome c oxidase subunit 1), psbA (PSII reaction center protein D1), and EF2 (elongation factor 2) sequence data for members of the tribe Corallineae was constructed to assess generic boundaries. We determined that traditional reliance on conceptacle position as an indicator of generic affinities in the Corallineae is not supported and taxonomic changes are required. We found that species currently assigned to Pseudolithophyllum muricatum resolved within the Corallineae in all analyses. This is the first record of crustose members in the subfamily Corallinoideae. Further‐more, the genus Serraticardia was polyphyletic; we propose to synonomize Serraticardia with Corallina, transfer the type species Smaxima to Corallina (Cmaxima (Yendo) comb. nov.), and describe the new genus Johansenia for Smacmillanii (Jmacmillanii (Yendo) comb. nov.). Our molecular data also indicate that species in the genus Marginisporum have evolutionary affinities among species of Corallina and these genera should also be synonymized. This necessitates the combinations Caberrans (Yendo) comb. nov. for Maberrans (Yendo) Johansen & Chihara, Ccrassissima (Yendo) comb. nov. for M. crassissimum (Yendo) Ganesan, and C. declinata (Yendo) comb. nov. for M. declinata (Yendo) Ganesan. Corallina elongata was divergent from all other members of Corallina and is transferred to a new genus, Ellisolandia (E. elongata (J. Ellis & Solander) comb. nov). In addition, COI‐5P and internal transcribed spacer (ITS) data combined with morphological characters were used to establish that rather than the four Corallina species recognized in Canada, there are nine.  相似文献

On the basis of comparative morphology and phylogenetic analyses of rbcL and LSU rDNA sequence data, a new genus, Gayliella gen. nov., is proposed to accommodate the Ceramium flaccidum complex (C. flaccidum, C. byssoideum, C. gracillimum var. byssoideum, and C. taylorii), C. fimbriatum, and a previously undescribed species from Australia. C. transversale is reinstated and recognized as a distinct species. Through this study, G. flaccida (Kützing) comb. nov., G. transversalis (Collins et Hervey) comb. nov., G. fimbriata (Setchell et N. L. Gardner) comb. nov., G. taylorii comb. nov., G. mazoyerae sp. nov., and G. womersleyi sp. nov. are based on detailed comparative morphology. The species referred to as C. flaccidum and C. dawsonii from Brazil also belong to the new genus. Comparison of Gayliella with Ceramium shows that it differs from the latter by having an alternate branching pattern; three cortical initials per periaxial cell, of which the third is directed basipetally and divides horizontally; and unicellular rhizoids produced from periaxial cells. Our phylogenetic analyses of rbcL and LSU rDNA gene sequence data confirm that Gayliella gen. nov. represents a monophyletic clade distinct from most Ceramium species including the type species, C. virgatum. We also transfer C. recticorticum to the new genus Gayliella.  相似文献

Analysis of nucleotide sequences from the domains 1 and 2 of the large-subunit rDNA demonstrated species of the Pichia fluxuum clade to be phylogenetically isolated, and domains 1 and 2 and internal transcribed spacer rDNA sequence analyses of strains phenotypically identified as P. fluxuum resulted in the discovery of three new species. From this work, the following new genus, new species, and new combinations are proposed: Kregervanrija gen. nov.; type species Kregervanrija fluxuum comb. nov. (type strain NRRL YB-4273, CBS 2287); Kregervanrija delftensis comb. nov. (type strain NRRL Y-7119, CBS 2614); Kregervanrija pseudodelftensis sp. nov. (type strain NRRL Y-5494, CBS 10105); Saturnispora besseyi comb. nov. (NRRL YB-4711, CBS 6343); Saturnispora mendoncae sp. nov. (type strain NRRL Y-11515, CBS 5620); and Candida abiesophila sp. nov. (type strain NRRL Y-11514, CBS 5366).  相似文献

The genus Pseudostegania Butler is revised. In addition to the two species known, four species are described as new: P. lijiangensis sp. nov. from Yunnan Province, P. qinlingensis sp. nov. from Gansu and Shaanxi Provinces, P. zhoui sp. nov. from Sichuan Province (China) and P. burmaensis sp. nov. from Burma (Myanmar); two species are newly combined with Pseudostegania: P. distinctaria (Leech, 1897), comb. nov. and P. yargongaria (Oberthür, 1916), comb. nov. All the known species are redescribed and lectotypes are designated for P. defectata (Christoph, 1881), P. distinctaria and P. yargongaria. The generic characters, based on all species, are summarized. The tribal placement of Pseudostegania is discussed. Illustrations of moths and genitalia are presented.  相似文献
