NEW COREIDAE FROM CHINA (HEMIPTERA, HETEROPTERA) Ⅲ.

Seventeen genera and twenty species of Coreidae are reported from China in thepresent paper, four species belonging to the subfamily Pseudophloeinae, six to Rhopalinaeand ten to Alydinae. Among them eight species are recorded for the first time from thiscountry, while all the remaining are described as new species. Four new genera are alsodescribed. The new genera and new species are briefly characterized below.     

NOVAJ KORIDALEDOJ EL GUANGXI,CINIO NEW FISHFLIES FROM GUANGXI,CHINA(Megaloptera:Corydalidae)

蟦科昆虫地理分布研究初探

In the present paper,the origin of the fa-mily Perlidae and the distribution characters of the tribe and the subfamily were summarized and analyzed.Based on the distribution of the genera in the world,the eight distribution types of the genera were divided.In addition,the distribution characters of the Perlidae in China were also probed preliminarily.So far two subfamilies,four tribe and twenty genera have been found in China.Ten of them,of which three genera are endemic to China,are the Oriental genera;one Palaearctic genus;three Oriental-Palaearctic genera;one Oriental-Nearctic genus;four Oriental-Palaearctic-Nearctic genera and one Oriental-Palaearctic-Nearctic-Afrotropical genus.Moreover,the main distribution character of Chinese Perlidae is that most of the species distribute Central China region,South China region and Southwest China region.The Central China region centralizes the distribution and the break of the perlid species,and made the dispersal for the others regions.     

FLORISTIC STUDY OF YUNNAN PROVINCE

Yunnan is a province rich in flora.There are about 13,000 species of 1,984genera among 240 families(230 families of Angiospermae according to Hutchin-son's system and 10 families of Gymnospermae)in Yunnan.The number offamily in Yunnan is about 79.73％ of 301 families in China,the number of genera64.88％ of 3,058 genera in China,and the number of species 52％ of 25,000species in China.The four very big families such as Orchidaceae,Compositae,     

A SUMMARIZED REPORT ON REDUVIINAE OF CHINA (HEMIPTERA: REDUVIIDAE)

The present paper enumerates 42 species of 16 genera of the subfamily Reduviinae discovered in China. Among them eight genera and 10 species are recorded for the first time from this country (new records marked with an) while 14 species are described as new to science. Acanthaspis aberrans China, representing the female of A. westermanni, is sunk as a junior synonym of A. westermanni Reut. Reduvius ursinus Jak., representing the female of R. fasciatus, is sunk as a junior synonym of R. fasciatus Reut. Keys to genera and species are given.     

NEW RECORDS OF CROTONIOIDEA FROM CHINA, WITH DESCRIPTION OF A NEW SPECIES OF ALLONOTHRUS (AGARI: ORIBAIDA)

A majority of known species of Crotonioidea inhabit leaf litter or upper soil horizons, where they feed on fungi or decomposing higher plant material; some inhabit specialized rnicro-habitats, such as tree, bog or spring. The superfamily encompasses, approximately 400 species representing 32 genera in nine families. Although this superfamily is relatively well known in the European and Soviet part of the Palearctic region, it is almost unknown in China.This paper reports 29 species of crotonioid mites in China representing 13 genera in 6 families. Among them one species is described as new and 27 species are recorded for the first time from China.     

Molecular phylogenetic relationships of Eastern Asian Cyprinidae (Pisces: Cypriniformes) inferred from cytochrome b sequences

Cyprinidae, the largest fish family, comprises ap-proximately 210 recognized genera and 2010 species that are distributed widely in Eurasia, East Indian Is-land, Africa, and North America[1]. Species richness of this family is the greatest in East Asia, for example, China has 122 genera and more than 600 species. It is difficult to build a comprehensive phylogeny of Cy-prinidae due to the large number of genera and species. The classification of this family has been subject to revisions an…     

SPECIES DIVERSITY AND COMMUNITY STRUCTURE OF SUCKING LICE IN YUNNAN, CHINA

On the basis of investigating 9 counties (towns) in Yunnan Province of China, the species diversity and community structure of sucking lice on the body surface of small mammal hosts are studied in the paper. Species richness (S) is used to stand for the species diversity. The calculation of community diversity index and evenness are based on Shannon-Wiener‘s method. 2745 small mammals captured from the investigated sites belong to 10 families, 25 genera and 41 species in 5 orders (Rodentia, Insectivora, Scandentia, Logomorpha and Carnivora) while 18165 individuals of sucking lice collected from the body surface of the small mammal hosts are identified into 4 families, 6 genera and 22 species. The species of sucking lice are much less than the species of their hosts. Most species of small mammals have their fixed sucking lice on their body surface. One species of small mammals usually have few species of sucking lice (1 to 4 species). The close species of the hosts in the taxonomy are found to have the same or similar dominant species of sucking lice on their body surface. The results reveal that the species diversity of sucking lice on small mammals is very low with a very simple community structure. The results also imply there may be a close co-evolution relationship between the lice and the hosts.     

FURTHER STUDY ON OSTRACODES FROM THE TAIYUAN FORMATION OF XINGYANG, GONGXIAN AREA, HENAN

The ostracodes were collected from the Taiyuan Formation of Xingyang, Gongxian area ,Henan. They comprise 35 species in 24 genera, of which 13 species in 7 genera are reported for the first time from China and 8 species in 2 genera are identified as planktonic elements. The discovery of planktonic ostracodes from the Taiyuan Formation is important for the reconstruction of palaeogeography and sedimentary history in this area during the
