对以色列地中海沿岸的几个葡萄孢属菌落进行了分析。描述了三个物种： B. leachii，由于体型较小，与从其他欧洲海域采集的标本不同，由于研究区域的特殊水文条件，被认为是侏儒症的一个例子； B. anceps，最初描述于印度-太平洋地区的物种，可能是从红海迁移而来；和新种 Botrylloides israeliense。讨论了葡萄属和类葡萄属之间的区别，并且基于系统结构差异的原始米尔恩-爱德华兹诊断被认为仍然有效。最后，分析了灰霉亚科特定分类学测定中常用的诊断特征。
Several botryllid colonies of the genus Botrylloides from the Mediterranean coast of Israel are analysed. Three species are described: B. leachii, which differs because of its smaller size, from specimens collected from other European seas and is considered a case of dwarfism due to the particular hydrological conditions of the study area; B. anceps, a species originally described from the Indo-Pacific region, which probably migrated from the Red Sea; and Botrylloides israeliense, a new species. The distinction between the genera Botryllus and Botrylloides is discussed, and the original Milne-Edwards diagnosis based on differences in the structure of the system is recognised as still valid. Lastly, the diagnostic features usually employed in specific taxonomic determinations of Botryllinae are analysed.
