中国新发现的有关玛利羊齿的材料

The Ostracods studied in this paper were collected by the members of a geologicalparty in 1955 from the yellowish silt-clay in Gansen district,Chaidam Basin.Accord-ing to the collecter's opinion,the geological age of the fossil bearing bed is Pliocene toQuaternary.The Ostracods are found in association with a charophyta,Chara gansenensis Wang(S.Wang,1961),gastropods and some indeterminable fragments of plant and fish bone.The species of Ostracoda described and illustrated in this paper are as follows:Ilyo-cypris gibba(Ramdohr),Eucypris inflata(Sars),Prionocypris gansenensis Huang(sp.nov.),Cypricercus brevis Huang(sp.nov.),Cypridopsis reticulata Huang(sp.nov.),Cyc-locypris serena(Koch),Candona neglecta Sars,C.houae Huang(sp.nov.),Limnocytheredubiosa Daday,L.sancti-patricii Brady et Robertson,L.binoda Huang(sp.nov.)andCyprideis littoralis(Brady).From the geological distribution of this Ostracod assemblage,the fossil bearing bedmay be of Pleistocene in age.

New ommatids from the Late Jurassic of western Liaoning, China （Coleoptera： Archostemata）

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.

GENUS EI：IOTIS MEYRICK （LEPIDOPTERA： OECOPHORIDAE） NEW FOR CHINA

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. 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.

A REVIEW OF THE GENUS A CRICOTOPUS KIEFFER （DIPTERA： CHIRONOMIDAE） IN CHINA

The genus Acricotopus Kieffer including three species from China is reviewed.Acricotopus lucens (Zetterstedt) is reexamined. Two species A. simplex sp. nov. and A.zhalingensis sp. nov. are described as male imagines. Acricotopus simplex sp. nov. was collected from Xizang, Sichuan and Qinghai Provinces; the species differs from others of the genus by the absence of hind tibial comb, temporal and clypeal seta. Acricotopus zhalingensis sp. nov. was collected from Qinghai Province; the species is recognized by a combination of characters: the larger body size; the clypeus without setae; anal lobe strongly produced, nearly hemispherical shape; inferior volsella triangular, strongly sclerotized; gonostylus with 13 very long setae. A key to the world males of the genus is presented. The generic diagnosis is emended.All the types described in this paper are deposited in Department of Biology, Nankai University,China (BDN).
