Revisión taxonómica de los géneros Oratha Walker 1863 y Hasodima Butler 1882 (Lepidoptera: Geometridae)
Revista chilena de historia natural , 2003, DOI: 10.4067/S0716-078X2003000100011
Abstract: the genera oratha walker 1863 and hasodima butler 1882 from central and southern chile are redefined and its species revised and described. the species are oratha significata walker 1863, h. elegans butler 1882, h. boreas (butler 1882) and h. bartletti sp. nov. the analysis of the types and the genitalia allow placing aconcagua fessa rindge in the synonymy of aconcagua parva (butler) comb. nov. all species and their genitalia and distribution are described and illustrated. a key for species of hasodima is provided. the monophyly of the genera and its relationships to the allied taxa are briefly discussed.

Campos Vázquez,Concepción;
Revista de Biología Tropical , 2000,
Abstract: crustaceans associated with macroalgae were collected for one year by scuba diving in bajo pepito, isla mujeres, mexican caribbean. a total of 148 organisms were found: three orders, 11 families, 18 genera and 19 species in nine types of associations. the order with highest abundance was isopoda (112), followed by amphipoda (20) and decapoda (16).
Taxonomy matters: Cognitive levels and types of mathematical activities in mathematics examinations
Margot Berger,Lynn Bowie,Lovemore J. Nyaumwe
Pythagoras , 2011, DOI: 10.4102/pythagoras.v0i0.4
Abstract: We argue that there are intrinsic difficulties in using the Subject Assessment Guidelines for Mathematics (SAGM) for evaluating the standard of a South African matriculation mathematics examination and for determining how it aligns with the curriculum. Our argument has two prongs. First, the SAGM taxonomy conflates cognitive level with type of mathematical activity; we contend that such a conflation leads to problems in assessing the complexity of the examination item. Second, the SAGM taxonomy provides no space for important mathematical activities such as justification and conjecturing despite the promotion of these activities in key curriculum documents (Department of Education, 2003). This absence may obscure weak alignment of the examination and the curriculum. These arguments are illustrated through examples taken from the 2008 Department of Education (DOE) and Independent Examination Board (IEB) Grade 12 Mathematics examination papers. We also examine other well‐known taxonomies in order to discern those aspects of a taxonomy which may be useful for evaluation and alignment. We conclude with the construction of a matrix that could provide an appropriate taxonomy for the South African matriculation Mathematics examination. It has activities on one axis and levels of complexity on the other.
The Application of XBRL in Enterprises’ Internal Control Report  [PDF]
Renyu Hu, Kaishi Ni
Theoretical Economics Letters (TEL) , 2015, DOI: 10.4236/tel.2015.52022
Abstract: With the broke out of Enron and the occurrence of other series of financial frauds, countries all over the world have paid more attention to corporate internal control management. This paper introduces current situation of internal control report of China’s listed companies and the development of XBRL and analyzes the advantage and feasibility of using XBRL as a disclosure measure of internal control report. Finally, we suggest setting up China’s XBRL taxonomy about internal control report, which is the core and contribution of this article.
Pollen of Bauhinia L. and Phanera Lour. (Leguminosae-Caesalpinioideae) from the Brazilian Caatinga  [PDF]
Francisco de Assis Ribeiro dos Santos, Danovan de Matos Novaes, Luciano Paganucci de Queiroz
American Journal of Plant Sciences (AJPS) , 2012, DOI: 10.4236/ajps.2012.37108
Abstract: A study of pollen morphology, in species of the genera Bauhinia and Phanera (Leguminosae-Caesalpinioideae) which occur in the Brazilian caatinga, is presented. The pollen was examined using light and scanning electron microscopy. Samples were prepared by the KOH method; non-treated pollen grains were examined by scanning electron microscopy. Pollen grains in Bauhinia species (11) are colpate, but porate in B. cheilantha and B. subclavata. All four species of Phanera present colporate pollen grains; P. outimouta is the only to have syncolporate pollen grains. Species of both genera present heteromorphism in the number of apertures. Excepting P. outimouta whose pollen grains are psilate, all species in the two genera present supratectal processes (gemmae/clavae), however the exine in the two genera are dif- ferent–semitectate, reticulate in Bauhinia species, and tectate, rugulate (or psilate) in Phanera ones. Pollen characters support the segregation of Phanera from Bauhinia.
Una nueva especie del género Cameronia Basir (Oxyurida: Thelastomatidae) parásita de Gryllodes laplatae Sauss (Orthoptera: Gryllidae) en Argentina
Reboredo,Guillermo R.; Camino,Nora B.;
Boletín chileno de parasitología , 2001, DOI: 10.4067/S0365-94022001000100011
Abstract: cameronia laplatae n. sp. found in city bell, argentina, parasitizing crickets is described and illustrated. the new species is distinguished from other members of the genus cameronia by the distribution pattern of the genital papillae in the male. it differs from all congeners mainly in having two pairs preanal y two pairs postanal papillae
Description of Micropygomyia (Sauromyia) vonatzingeni sp. nov. (Diptera, Psychodidae, Phlebotominae) from the states of Pará and Tocantins, Brazil
Galati, Eunice A. Bianchi;
Revista Brasileira de Entomologia , 2007, DOI: 10.1590/S0085-56262007000400007
Abstract: both sexes of a new phlebotomine sandfly species micropygomyia (sauromyia) vonatzingeni sp. nov. (diptera, psychodidae), captured in the serra das andorinhas, s?o geraldo do araguaia municipality, pará state, and cavalcante municipality, tocantins state, brazil, are described and illustrated. this new species belongs to the oswaldoi series and its distinction from the other extant species of the series was made by male and female identification keys. the specific geographical distribution of the oswaldoi series by country and department (or state) is presented.
Coenosia wulpi (Pont) (Diptera, Muscidae, Coenosiinae): redescription of male, description of female and terminalia
Couri, Márcia S.;
Revista Brasileira de Zoologia , 2007, DOI: 10.1590/S0101-81752007000200014
Abstract: coenosia wulpi pont, 1972 (diptera, muscidae, coenosiinae) is the only coenosia meigen, 1826 species recorded from mexico. it is known only from the holotype male deposited at "the natural history museum" collection (london, united kingdom). a series of five males and seven females was found at california academy of sciences collection (san francisco, california), which enabled the redescription of the male, and the description of the female and the male and female terminalia, for the first time.
