华南泥盆纪分形类豆石分类一新族Sinoleperditiini

在华南,迄今只在泥盆纪地层中发现豆石介类（ｌｅｐｅｒｄｉｔｉｉｄｓ）。由于它们均具有下垂“Ｖ”字型肌痕且此肌痕随时间的推移不断向下延伸,被考虑是豆石介类中一独立的演化支系,并归一新族：Ｓｉｎｏｌｅｐｅｒｄｉｔｉｉｎｉ。此族,在华南地区含２属和６亚属：Ｓｉｎｏｌｅｐｅｒｄｉｔｉａ（Ｓｉｎｏｌｅｐｅｒｄｉｔｉａ）Ｗａｎｇ,１９８９,Ｓ．（Ｐｓｅｕｄｏｂｒｉａｒｔｉｎａ）ｓｕｂｇｅｎ．ｎｏｖ．,Ｓ．（Ｙａｏｓｕｏｌｅｐｒｄｉｔｉａ）ｓｕｂｇｅｎ．ｎｏｖ,Ｐａｒａｍｏｅｌｌｅｒｉｔｉａ（Ｐａｒａｌａｐｅｒｄｉｔｉａ）Ｓｕｎ,１９７８,Ｐ．（Ｐａｒａｍｏｅｌｌｅｒｉｔｉａ）Ｗａｎｇ,１９７６和Ｐ．（Ｂｒｅｖｉｌａｐｅｒｄｉｔｉａ）ｓｕｂｇｅｎ．ｎｏｖ．。重点探讨了此族的起源,演化型式及趋势和绝灭。指出“Ｖ”字型或下垂“Ｖ”字型肌的功能与闭壳肌可能是异曲同功,起闭壳作用;放射和横向条纹可能是闭壳肌和下垂“Ｖ”字型肌频繁收缩所致而不是血管束的痕迹,并可能具有排泻作用;ＤａｌｅｌｉｎａＳｕｎ,１９７８是ＰａｒａｌｅｐｅｒｄｉｔｉａＳｕｎ,１９７８的同物异名;ＰａｒａｅｏｌｏｐｅｒｄｉｔｉａＡｄａｃｈｉｅｔＩｇｏ,１９８０属

Punctelia, a new lichen genus in the Parmeliaceae

The genus Punctelia Krog gen. nov., comprising subgen. Punctelia (the Parmelia borreri group) and subgen. Flavopunctelia Krog subgen. nov. (the Parmelia flaventior group), is here segregated from Parmelia s. str. The main differences between the two genera lie in the development of the pseudocyphellae, the chemical properties of the medulla, and the centres of distribution. Parmelia s. str. has its highest number of species in East Asia and the Australian region, Punctelia in the Americas and Africa.     

Morphological classification of loaches (Nemacheilinae)

Comprehensive comparative morphological analysis of loaches from the subfamily Nemacheilinae is conducted. Forty significant phylogenetic characters are suggested, and phylogenetic relationships are reconstructed. The subfamily Nemacheilinae is subdivided into five tribes (Vaillantellini, Lefuini nov., Yunnanilini nov., Triplophysini nov., and Nemacheilini), and the relationships between these tribes can be expressed by the following formula: Vaillantellini (Lefuini (Yunnanilini (Triplophysini + Nemacheilini))). The classification of highland Asian loaches (Triplophysini) is specified, and the revised diagnoses of the genera from this tribe are given. Heterogeneity of the genus Triplophysa is demonstrated. This genus can be divided into several subgenera, and three new subgenera (Labiatophysa subgen. nov., Indotriplophysa subgen. nov., and Tarimichthys subgen. nov.) are described. A new species Hedinichthys grummorum sp. n is described from the Turpan Depression (northwest China).     

Infrageneric division of the genus Hypecoum (Papaveraceae)

The genus Hypecoum (Papaveraceae) is subdivided into five sections. Two of them (sect. Chiazospermum and sect. Leptocarpae sect, nov.) are comprised in subgen. Chiazospermum , and three in subgen. Hypecoum (sect. Hypecoum , sect Pendulae sect. nov., and sect. Mnemosilla comb, et stat. nov.). The morphology of the sections is discussed, and a hypothesis of the possible course of evolution within the genus is presented. Chromosome numbers are given for seven taxa.     

A phylogenetic study of the Plantaginaceae

In a study based on morphological, embryological and chemical data of the Plantaginaceae, within the subclass Sympetalae or Asteridae, the superorder Lamianae is shown to be monophyletic. However, it was not possible to reconstruct the phylogeny within Lamianae or to find a sister-group for the monophyletic Plantaginaceae – Hydrostachyaceae for the latter is rejected. Three or rarely four genera have previously been recognized within Plantaginaceae, but in both cases Plantago appears as polyphyletic, which is considered unacceptable. Six clades are recognized as subgenera within Plantago: subgen. Plantago (c. 131 species), subgen. Coronopus (c. 11 species), subgen. Littorella (three species), subgen. Psyllium (c. 16 species), subgen. Bougueria (one species), and subgen. Albicans (51 species). Within P. subgen. Plantago, the paraphyletic sect. Plantago (c. 42 species) is found in all parts of the world except South America, New Zealand, Australia, and New Guinea, where sect. Oliganthos and sect. Mesembryniae vicariate. It is not possible to infer the phylogeny within sect. Plantago, for example between the endemic species from distant Pacific Islands; their common ancestor might be a species that once had a very wide distribution. Keys to genera, subgenera, sections and series are given. Only one genus, Plantago L., is recognized. The following proposals are made in the Appendix: P. ser. Oliganthos Rahn, ser. nov.; P. ser. Carpophorae (Rahn) Rahn, stat. nov. (= sect. C.); P. ser. Microcalyx (Pilg.) Rahn, stat. nov. (= sect. M.); P. unibrackteata Rahn, nom. nov. (=P. uniflora Hook.f. non L.); P. subgen. Littorella (P. J. Bergius) Rahn, stat. nov. (=Littorella P. J. Bergius); P. araucana Rahn, nom. nov. (=Littorella australis Griseb. non Plantago australis Lam.); P. americana (Fernald) Rahn, comb. nov.(=Littorella a.); P. subgen. Bougueria (Decne.) Rahn, stat. nov. (=Bougueria Decne.); P. nubicola (Decne.) Rahn, comb. nov. (=Bougueria n. Decne.); P. subgen. Albicans Rahn, subgen. nov. Ten lectotypes are selected.     

New subgenus of the genus Schizoprymnus (Hymenoptera: Braconidae) from Japan, having a unique abdominal carapace structure

A new subgenus of the genus Schizoprymnus Foerster is described and figured from Honshu, Japan. The subgenus, Ibarakius subgen. nov., comprises three species, S. (I.) gotoi sp. nov. (type species), S. (I.) kaizawus sp. nov., and S. (I.) honshuensis sp. nov. A pair of long, curved posteroventral processes on the carapace is unique to Ibarakius subgen. nov. The variability of frontal protuberances and sutures of the carapace in the brachistine genera Triaspis Haliday and Schizoprymnus Foerster is discussed.     

也论寒武纪原德氏虫属（Prodamesella Chang）

湘西Prodamesella punctata Ergaliev的个体发育头盖的研究和确凿尾部的发现对袁金良、尹恭正（2000）有关Prodamesella 属的次级划分和科级分类位置的最新论点提出疑问。湘西的材料表明,他们建立新的分类单元的材料中,头盖多属幼年个体而尾部似与Prodamesella无关。认为新亚属Prodamesella Chang（Metaprodamesella) Yuan et Yin和Prodamesella Chang（Neoprodamesella)Yuan et Yin不能成立。以往描记的P.subtriangulata Peng,P.(Prodamesella)cylindrica Yuan et Yin,P.(Metaprodamesella)subtriangulata prisca Yuan et Yin P.(Metaprodamesella)granulosa Yuan et Yin和Prodamesella(Neoprodamesella)spinosa Yuan et Yin5种（亚种）均系P.punctata的晚出异名。Prodamesella的特征表明,它既不归属于Damesellidae科也不属于Missisquoiidae科。它的科级位置目前尚不明了。     

New subgenus of genus Hylaeus (Hymenoptera: Colletidae) with two new records from China

A new subgenus of the genus Hylaeus Fabricius, 1793 is described and illustrated. The subgenus Laxoprosopis subgen. nov. is erected for one new Chinese species, H. (Laxoprosopis ) sichuanensis sp. nov. In addition, H. nipponicus Bridwell, 1919 and H. monticola Bridwell, 1919 are recorded from China for the first time.     

论晚寒武世原太子河虫（Prpotaitzehoia Yang） 的分类位置

据贵州东部万山镇南部寄马冲至羊尾剖面晚寒武世早期车夫组三叶虫的新材料,对原太子河虫属（Protaitazuhoia Yang,1978)进行了修订。根据其尾部的特征,将其分类位置由原先的德氏虫科（Damesellidae Kobayashi,1935）移至鄂尔多斯虫科（Ordosiidae Lu,1954)。此外,还描述了原太子河虫2新种1新亚种：Protaitze-hoia latelimbata sp.nov.,Protaitzehoia nitida sp.nov.,Protaitzehoia quadrata jimachongensis subsp.nov。     

A new species of Phyllanthus (Phyllanthaceae) from Chapada Diamantina, Bahia, Brazil

During a study of the genus Phyllanthus (Phyllanthaceae) in Chapada Diamantina, Bahia, a new species Phyllanthus gongyloides Cordeiro & Carneiro-Torres sp. nov. was found and is described and illustrated here. It is probably endemic to the area and is placed in subgen. Phyllanthus , sect. Phyllanthus , subsect. Clausseniani G. L. Webster. A new couplet to Webster's available key to the subsection is provided . © 2004 The Linnean Society of London, Botanical Journal of the Linnean Society , 2004, 146 , 247–250.
