Abstract

ABSTRACT Trematodonl laetevirens Hakelier & J.-P. Frahm is here added to the Russian bryoflora based on records from the Khibiny Mts. (Murmansk Region, North-West Russia), Anadyr' River Basin (Chukotka Autonomous Region) and the Ushkovsky volcano (Kamchatka Peninsula). The Khibiny moss population, earlier defined as T. brevicollis Hornsch., is attributed to T. laetevirens. We reaffirmed that the East Sayan samples belong to T. brevicollis, so, currently only one locality of T. brevicollis is known in Russia. The revision of T. longicollis Michx. samples from the Kamchatka Peninsula, and Kunashir Island (the Kuril Islands) confirmed their affiliation to this species, despite some deviations in morphological features. The taxonomical concepts inferred from variation in morphological traits are supported by for the first molecular-phylogenetic analyses of the genus Trematodon based on the nucleotide sequence data of ITS2 nrDNA and trnL-F cpDNA. At present, four species of the genus Trematodon Michx. are known from Russia: T. ambiguus (Hedw.) Hornsch., T. brevicollis, T. laetevirens and T. longicollis. A key to Russian Trematodon species is provided.

Trematodon laetevirens Hakelier & J. p。Frahm和T. brevicollis Hornsch。俄罗斯

[摘要]龋病防治[j]。根据来自希比尼山脉(俄罗斯西北部摩尔曼斯克地区)、阿纳德尔河流域(楚科奇自治区)和乌什科夫斯基火山(堪察加半岛)的记录，弗拉姆被添加到俄罗斯苔藓植物中。希比尼苔藓种群，早先被定义为T. brevicollis Hornsch。这是由T. laetevirens引起的。我们确认东萨扬的样本属于短链绦虫，因此，目前在俄罗斯只知道一个短链绦虫的地点。长鼻绦虫的修订。堪察加半岛和库纳希尔岛(千岛群岛)的标本证实了它们属于这个物种，尽管在形态特征上有一些偏差。基于ITS2 nrDNA和trl - f cpDNA的核苷酸序列数据，首次对吸虫属进行了分子系统发育分析，支持了从形态特征变异推断的分类概念。目前发现吸虫属4种。来自俄罗斯:T. ambiguus (Hedw.)Hornsch。短支绦虫、长支绦虫和长支绦虫。提供了俄罗斯吸虫种类的分类表。
