Aedes(S.)scutellaris(Walker,1859)(盾纹伊蚊)过去在我国台湾、广东、云南等地都有记载。现知其指名亚种s.scutellaris为巴布亚种类,分布于印度尼西亚和新几内亚。最近我们检视了广东和云南的本种标本,发现它们实系另一亚种,即scutellaris malayensis Colless,1962。它与指名亚种的外表十 相似文献

Cacatuocotyle paranaensis n. sp. (Dactylogyridae, Ancyrocephalinae) is described from the gills of the characid fishes Characidium lanei Travassos and C. pterostictum Gomes collected from two streams on the coast of the State of Paraná, Brazil. Cacatuocotyle n. g. is proposed for species possessing a single cephalic lobe (terminal), one pair of head organs, a convex haptor with thickened muscular anterior margins, one anchor-bar complex (ventral), seven pairs of ventral hooks (one pair associated with the anchor shafts; one central pair anterior to the bar; five submarginal bilateral pairs) and a sinistral vaginal aperture. 相似文献

Based on a further re-examination of loricate choanoflagellate species with detailed morphological (SEM/TEM) and molecular data of the SSU and LSU rRNA, the present study aims to give new insights for Stephanoeca cupula. In contrast to the original allocation within the family of tectiform reproducing species, morphological and molecular data of S. cupula sensu Leadbeater, 1972 points towards an affiliation within the nudiform reproducing family. Based on these new data, we here erect the nudiform genus Kalathoeca with its type species K. cupula gen. et comb. nov. Our data challenges morphological species assignments, as K. cupula shares its morphological lorica characteristics with tectiform reproducing species of Stephanoeca sensu stricto. Kalathoeca cupula is an interesting candidate for further investigating and understanding the evolutionary relationship of tectiform and nudiform reproducing species.Stephanoeca cupula sensu Thomsen, 1988 has been morphologically re-examined based on the renewed understanding of the morphological variability associated with S. cupula sensu Leadbeater, 1972 (=K. cupula), allowing us now to distribute the different morphological forms investigated within K. cupula and Pseudostephanoeca quasicupula. 相似文献

When studying house‐dust biology, one deals with a huge amount of data. In order to work on the data in an orderly and efficient way a computerized database has been developed for storing data found in field experiments. Six levels in this biological database characterize the home, the room and the substrate from which the sample has been taken, the sample taken from the substrate, the analyzed fraction taken from the sample and the arthropodal, fungal, guanine and mite antigen content of the fraction. In total thirteen files are being used for storing the data. As a database management system dBASE II is used. Interfaces with other computer programs are possible such as SPSS (Statistical Package for Social Sciences), BMDP (Biomedical Computer Programs), Wordstar, Basic interpreter and SIR (Scientific Information Retrieval). With the aid of this software it is possible to store, revise and retrieve the data easily and to draw conclusions in the field of ecology. An example shows some features of this database. 相似文献
