Abstract

: Xiphidiocercariae is a non-taxonomic group of digenean larvae. These small cercariae are characterized by complex morphology, which complicates their accurate identification. Recently, we have devoted a series of papers to the least studied groups of xiphidiocercariae — Cercariae virgulae and Cercariae microcotylae . Here we present the morphological description and molecular phylogenetic analysis of the new microcotylous cercaria. We have identified morphological features that allow us to distinguish this larva from all previously described cercariae. This species lacks virgula organ and possesses three pairs of penetration glands and Y-shaped excretory bladder. Molecular phylogenetic analysis performed with 28S rDNA and cox 1 mtDNA sequences made it possible to confirm the taxonomic position of this cercaria within the family Prosthogonimidae, and to determine its species identity as

透明假体剑状尾蚴的形态描述及系统发育位置

剑蝗尾蚴是一种非分类学的地沟虫幼虫。这些小尾蚴的特征是复杂的形态，这使得它们的准确鉴定变得复杂。最近，我们专门发表了一系列关于剑尾尾蚴研究最少的类群——vircariae和microcotylaae尾蚴的论文。本文报道了新型微子叶尾蚴的形态描述和分子系统发育分析。我们已经确定了形态特征，使我们能够将这种幼虫与以前描述的所有尾蚴区分开来。本种无处女器官，有三对穿透腺和y形排泄膀胱。利用28S rDNA和cox 1 mtDNA序列进行分子系统发育分析，确定了该尾蚴在假蝇科中的分类位置，并确定了其物种身份

期刊介绍： Scientific peer-reviewed journal INVERTEBRATE ZOOLOGY publishes original papers, reviews and brief communications on morphology, anatomy, embryology, taxonomy, phylogeny, and ecology of any group of invertebrates from protistans to lower chordates. INVERTEBRATE ZOOLOGY accepts manuscripts in English or Russian and publishes them in printed and electronic versions. The Russian translations of English titles, abstracts and figure captions of the papers written by non-Russian authors can be provided by the editors. Invertebrate Zoology invites authors to publish extended monographic manuscripts after usual reviewing procedure. The monographic manuscripts can include up to 400 thousand letters and be prepared in English or in Russian. Accepted monographic manuscripts will have priority to be published in the nearest issue of the journal.
