TAXONOMIC STUDY OF TWO NEW GENERA OF FUSIFORM GREEN FLAGELLATES, TABRIS GEN.

JOURNAL OF PHYCOLOGY, Issue 2 2009

On the basis of LM, we isolated strains of two species of fusiform green flagellates that could be assigned to former Chlorogonium (Cg.) Ehrenb. One species, "Cg."heimii Bourr., lacked a pyrenoid in its vegetative cells and required organic compounds for growth. The other was similar to Cg. elongatum (P. A. Dang.) Francé and "Cg."acus Nayal, but with slightly smaller vegetative cells. Their molecular phylogeny was also studied based on combined 18S rRNA, RUBISCO LSU (rbcL), and P700 chl a -apoprotein A2 (psaB) gene sequences. Both species were separated from Chlorogonium emend., Gungnir Nakada and Rusalka Nakada, which were formerly assigned to Chlorogonium. They were accordingly assigned to new genera, Tabris Nakada gen. nov. and Hamakko (Hk.) Nakada gen. nov. as T. heimii (Bourr.) Nakada comb. nov. and Hk. caudatus Nakada sp. nov., respectively. Tabris is differentiated from other genera of fusiform green flagellates by its vegetative cells, which only have two apical contractile vacuoles and lack a pyrenoid in the chloroplast. Hamakko, on the other hand, is distinguishable by the fact that its pyrenoids in vegetative cells are penetrated by flattened thylakoid lamellae. [source]


Taxonomic Study of Korean Oedipodinae (Orthoptera: Caelifera: Acrididae)

ENTOMOLOGICAL RESEARCH, Issue 2 2005
Tae-Woo KIM
ABSTRACT As a result of Korean Oedipodinae is taxonomically revised, eleven species are recognized and Microgastrimargus taeguensis Lee and Park 1992 is a new synonym of Oedaleus infernalis Saussure 1884. A key to Korean species of Oedipodinae, and description of a little known species Epacromius japonicus (Shiraki 1910) are provided. [source]

Jin Young PARK
ABSTRACT Last instar larvae of Pyrrhalta annulicornis, P. fuscipennis, P. humeralis, P. lineola and P. maculicollis are described and illustrated for the first time in Korea. Their taxonomic remarks, tubercle patterns and a key are also given. [source]


A Taxonomic Study of Immature Stage in Three Species of the Genus Protaetia Burmeister (Coleoptera: Scarabaeoidea, Cetoniidae) from Korea

ENTOMOLOGICAL RESEARCH, Issue 4 2003
Mi Ae KIM
ABSTRACT ABSTRACT The third instar larvae of Korean Protaetia spp., P. brevitarsis seulensis (Kolbe), 1886, P. orientalis submarmorea (Burmeister), 1842, and P. mandschuriensis (Schürhoff), 1933, are described. The larva of the second species is the first record in this genus. A taxonomic key, descriptions, and illustrations of the three species are provided. [source]


Taxonomic Study of the Genus Conocephalus Thunberg in Korea (Orthoptera: Tettigoniidae: Conocephalinae)

ENTOMOLOGICAL RESEARCH, Issue 1 2002
Tae-Woo KIM
ABSTRACT The genus Conocephalus Thunberg in Korea was taxonomically studied. As the result, five species were confirmed to Korean fauna including a newly recorded species, Conocephalus bambusanus Ingrisch. The key to species, distributional data and comparative figures for identification are given. [source]

Tau KANG
ABSTRACT We examined newly recorded species, Pseudoabsidia ussurica Wittmer, from Korea. The species was redescribed with their color variation. Also, the photos of adult habitus and aedeagus are provided. [source]


Taxonomic study of Drepanellus gen. n. (Coleoptera, Scarabaeidae, Oniticellini), with the description of two new species

MITTEILUNGEN AUS DEM MUSEUM FUER NATURKUNDE IN BERLIN-DEUTSCHE ENTOMOLOGISCHE ZEITSCHRIFT, Issue 2 2009
Enrico Barbero
Abstract In this paper we describe Drepanellus gen. n. (subtribe Drepanocerina) from the Afrotropical Region. The new genus includes three species: Drepanellus laticollis comb. n. (formerly placed in the genus Drepanocerus Kirby), and two new species, Drepanellus simonisi sp. n. and D. nicolasi sp. n., that are identified and described here. Lectotype of D. laticollis is designated here. We also provide the key to these species, as well as distribution and ecological notes inferred from collection data.

Taxonomic study of Malus section Florentinae (Rosaceae)

BOTANICAL JOURNAL OF THE LINNEAN SOCIETY, Issue 2 2008
GUAN-ZE QIAN
Malosorbus Browicz, an intergeneric hybrid between the genera Malus Mill. and Sorbus L. proposed by Browicz, is suggested to be a section of the genus Malus Miller in the present study based on a comparison of the morphology and experimental data of the taxon and its closely related taxa. Section Florentinae was invalidly published by Cheng et al. and is now validated by the addition of a Latin description, type species, and basionym citation. The new section differs from Malus section Sorbomalus (Zabel) C.K.Schneid. mainly by its partly free top of fruits and five styles with villous at the base, and from Malus section Eriolobus (Seringe) C. K. Schneid. by its five styles with villous at the base and deciduous sepals. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158, 223,227. [source]


Taxonomy of the genus Rhizophagus Herbst (Coleoptera: Monotomidae: Rhizophaginae) in Korea

Sun-Jae PARK
Abstract A taxonomic study of the genus Rhizophagus Herbst in Korea is presented. Three species ,Rhizophagus (Anomophagus) puncticollis Sahlberg, Rhizophagus (Rhizophagus) japonicus Reitter and Rhizophagus (Rhizophagus) nobilis Lewis , are recognized. The genus and species are recorded for the first time in Korea. A key, habitus photos, descriptions, and illustrations of diagnostic characters of known Korean Rhizophagus species are given.

Palynotaxonomy of Brazilian species of Polygala subgenus Hebeclada

BOTANICAL JOURNAL OF THE LINNEAN SOCIETY, Issue 4 2008
ANA CRISTINA ANDRADE DE AGUIAR
This study used pollen morphology to address taxonomic controversies related to several species belonging to subgenus Hebeclada of the genus Polygala (Polygalaceae). According to the last traditionally accepted revision of this subgenus, it comprises 40 species. Nevertheless, a recent taxonomic treatment applying more comprehensive criteria reduced this number to only nine species. Our work focused on 15 traditionally accepted species that occur in Brazil, fourteen of which have been considered as only six species in this recent taxonomic study. Pollen grains from floral buds at pre-anthesis were collected from herbarium specimens and analysed using both visible light and scanning electron microscopy. Most of the traditionally accepted species were distinguished by different combinations of several pollen-related features, in particular colpi number (13 or 15), pollen size and shape, and endoaperture type (endocingulate or not) and arrangement (parallel or sinuous). The species accepted in the recent taxonomic treatment could not be discriminated by pollen characters. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 157, 609,619.
