The Lower Cambrian univalved molluscs described in the present paper were collected in 1977—1978 by the geological parties from the base of the Xidashan Formation around Xidashan, Kuruktag, Xinjiang. The material is generally well-preserved and includes three species ascr bed to three genera, in which one genus and three species are new, namely, Helcionella xinjiangensis sp. nov., Eocyrtolites radiatus gen. et sp. nov., and Cyrtodiscus? kuruktagensis sp. nov..Among them, the genus Helcionella is a common from in the Cambrian in many parts of the world, and it also has been reported from the Cambrian formations of the North China Province and from the Huangshandong Member of the Lower Cambrian Tongying Formation of the Yangtze Provinnce in China.  相似文献

Two new species of the genus Eumyllocerus Sharp, 1896, of the subfamily Entiminae Schoenherr, 1823, are described from China. Eumyllocerus longisetus sp. n. may be distinguished from other species of the genus by its long bristle-like, erect setae on the intervals, each of which is longer than the width of the second interval, the setae arrangedin double rows, and its shell-like, shiny, dense, metallic green scales. Eumyllocerus rotundicorpus sp. n. may be distinguished from any other Eumyllocerus species by its oval and inflated elytral shape, short stout metepisternum, small humeri, elytral setae shorter than 0.5 times the width of the second interval, the setae arranged in double rows, and its golden copper and pearl gray scales. The taxonomy of the genus is discussed. The two new species are described and habitus photographs and figures of diagnostic characters are provided. The type specimens of the new species are deposited in the Institute of Zoology, Chinese Academy of Sciences, Beijing, China (holotype and paratypes) and the Korean Entomological Institute, Korea University, Seoul, Korea (paratypes).  相似文献

A new genus Amblomma gen. nov. of fossil beetles is erected and can be assignedto the family Ommatidae because its two procoxal cavities are contiguous and the articulations of the abdominal ventrites are abutting. The new genus is similar to Zygadenia Handlirsch, 1906 (=Notocupes Ponomarenko, 1964), Tetraphalerus Waterhouse, 1901,Rhobdocupes Ponomarenko, 1966 and Sinocupes Lin, 1976, but can be distinguished from other genera according to the following characters: the second segment of antennae is shorterthan the third one in length; the posterior tarsi with the basal segment is obviously shorter than the three following taken together in length; the antennae reach the posterior ridge of prothroax in length, and the sides of the prothroax with serrulate margin. Four new species of the new genus are described and figured: Amblomma psilata gen. et sp. nov., Amblomma rudis gen. et sp. nov., Amblomma epicharis gen. et sp. nov., and Amblomma stabilis gen. etsp. nov. A key to species within this new genus is provided. All the specimens are collected from the Late Jurassic Yixian Formation of western Liaoning and are now housed in the College of Life Science, Capital Normal University, Beijing, China.  相似文献

A revision of the genus Trixa Meigen (Diptera: Tachinidae)   总被引:1,自引:0,他引:1  
The genus Trixa Meigen, 1824 is revised. Dexiotrix Villeneuve, 1936 and Trixella Mesnil, 1980, each of which was sometimes treated as a distinct genus, are treated as junior synonyms of Trixa Meigen. Two species from Sichuan and Yunnan, China, are described as new to science, viz. Trixa chinensis sp. nov. and T. chaoi sp. nov. T. alpina Meigen is treated as a junior synonym of T. caerulescens Meigen. T. nox (Shima) and T.pubiseta (Mesnil) are newly recorded from China. Males of T. pubiseta (Mesnil) and T.longipensis (Villeneuve) are described for the first time. Diagnoses, figures and a key to twelve species in Trixa are given.  相似文献

This paper reports the genus Erotis Meyrick for the first time from China. Two new species Erotis expansa sp. nov. and Erotis punctalosa sp. nov. are described. E. expansa sp. nov. is related to E. phosphora Meyrick both in appearance and in the male genitalia, but can be differentiated from the latter by uncus broader and slightly concave at middle of caudal margin, gnathos nearly as long as uncus and valva with costa almost straight in the male genitalia. E. punctalosa resembles E. expansa sp. nov. externally, but can be easily distinguished from the latter by the female genitalia: eighth tergite caudally almost straight; two signa large thorn-like, basal plate irregularly triangular in shape, with fine spines along anterior margin. The photographs of the adults and the genital structures of the new species are provided. A key to all the known species of Erotis is given.  相似文献

The genus Girardia(Tricladida: Dugesiidae) was recorded in China for the first time. A new freshwater turbellarian species, G. sinensis Chen & Wang, sp. nov., is described, which was collected from Xinghu Lake, Zhaoqing, Guangdong Province, China. Observation and analysis of the new species was conducted on morphology, habits, reproduction, histochemistry and molecular phylogenetics. In addition, the results indicated that morphological differences of ACh E+ nerve structure can be used as a distinguishable character for species identification of Dugesiidae.  相似文献

Rheocricotopus (Psilocricotopus) taiwanensis sp. n. from Taiwan, China, is described as male imagines. The species is allied to R. (P.) chalybeatus (Edwards) but it is easily separated from the latter in lacking setae in all reins, much lower AR and more pronounced crista dorsalis in gonostylus. The genus is new to Taiwan Province, China. The specimen is deposited at the Department of Biology, Nankai University, Tianjin.  相似文献

Thirty species belonging to 13 genera of three families in the Hippolytidae Bate, 1888(sensu lato) are reported in the present paper, including two new species and two newly recorded ones from the China seas. The two new species are named as Thinora leptochelus sp. nov. and Thor singularis sp. nov. Thinora leptochelus sp. nov. differs from the only knwon species of the genus, Thinora maldivensis(Borradaile, 1915), by the developed supraorbital tooth and the slender and cone-shaped chelae of the first 2 pereopods. Thor singularis sp. nov. can be dinstingershed from the other members of the genus Thor by the first 2 pereopods with epipods. The two newly recorded species from China seas are Eualus kikuchii Miyake & Hayashi, 1967 and Heptacarpus commensalis Hayashi, 1979.  相似文献

青海特蚋亚属一新种(双翅目:蚋科)   总被引:4,自引:0,他引:4  
Simulium (Tetisimulium) xiaodaoense sp. nov. is described based on the female specimens collected from Qinghai, China. This species is assigned to the subgenus Tetisimulium, and is closely related to S. (T.) tachengense An and Mahe, 1994 and S. (T.) wutaishanense An and Yan, 2003. However, it is clearly differentiated from them by the structure of gonapophyses, genital fork, genital plate, paraproct and cercus of the female.
