云南产凤尾蕨属植物(凤尾蕨科)的新修订

在《中国植物志》和《云南植物志》的基础上,对云南产凤尾蕨属植物进行新的分类修订。文中澄清了8个混淆类群,其中新等级1种,即高原凤尾蕨Pteriscuspigera(Chingex Ching et S.H.Wu)X.Q.Song;云南分布新记录1种,即假指状凤尾蕨Pteris psudodactylina Ching et S.K.Wu;新异名3个,即Pteris asperi-caulis var.cuspigera Chingex Ching et S.H.Wu,Pteris inaequalis Bak.及Pteris wallichiana var.yunnanensis(Christ)Ching et S.H.Wu。还列出了新修订种类的文献引证、标本引证、生境和地理分布。经该文研究确认,现知云南有该属植物48种。     

楼梯草属研究随记

在该文中首次给出革叶楼梯草的雄头状花序描述;还给出樱叶楼梯草雄头状花序的修正描述和兜苞墨脱楼梯草的修正特征集要;写出托叶楼梯草和南川楼梯草二种的分类学修订,其中包括2新变种和2新等级;描述了小叶楼梯草组的1新种和骤尖楼梯草组的3新种;数年前被归并为异名的兜苞墨脱楼梯草和五肋楼梯草得到恢复。     

Revision of “Phyllobrotica” from Taiwan with description of Jolibrotica gen. n. (Coleoptera,Chrysomelidae, Galerucinae)

All Taiwanese species formerly classified the genus Phyllobrotica Chevrolat, 1836 are revised. Jolibrotica Lee & Bezděk, gen. n., is described for Phyllobrotica sauteri (Chûjô, 1935) (Taiwan, China: Guangxi) and Phyllobrotica chujoi Kimoto, 1969 (Taiwan). Phyllobrotica shirozui Kimoto, 1969 is transferred to the genus Haplosomoides. All species are redescribed and their diagnostic characters illustrated.     

Anatomy,relationships and distribution of Taiwanassiminea affinis (Böttger) (Caenogastropoda: Assimineidae), with a reassessment of Cyclotropis Tapparone-Canefri

Oleg Grigor’evich Kusakin As a Biogeographer

Oleg Grigorevich Kusakin (1930–2001) was one of the greatest specialists in marine biogeography. His contribution was especially significant in the geographical zonation of cold and temperate waters of the Northern and Southern Hemispheres, into the unification of biogeographical terminology and nomenclature of the units of biogeographical zonation, and into the solution of the problem about the age and modes of the origin of the deep-sea fauna in the World Ocean.Original Russian Text Copyright © 2005 by Biologiya Morya, Kafanov.     

Diversity of Halimeda (Bryopsidales,Chlorophyta) in New Caledonia: a Combined Morphological and Molecular Study

Halimeda is a genus of calcified and segmented green macroalgae in the order Bryopsidales. In New Caledonia, the genus is abundant and represents an important part of the reef flora. Previous studies recorded 19 species that were identified using morphological criteria. The aim of this work was to reassess the diversity of the genus in New Caledonia using morpho‐anatomical examinations and molecular analyses of the plastid tufA and rbcL genes. Our results suggest the occurrence of 22 species. Three of these are reported for the first time from New Caledonia: Halimeda kanaloana, H. xishaensis, and an entity resembling H. stuposa. DNA analyses revealed that the species H. fragilis exhibits cryptic or pseudocryptic diversity in New Caledonia. We also show less conclusive evidence for cryptic species within H. taenicola
