Abstract

The parasite fauna of Neotropical reptiles is poorly known, and the number of parasites described in these hosts does not seem to correspond to the actual species diversity in this zoogeographical region. This also applies to tapeworms such as proteocephalids, which are rarely found in reptiles and are strictly specific to their reptilian hosts. In the present paper, three new species of Ophiotaenia La Rue, 1911 are described from three dipsadine snake species (Squamata: Colubridae) in Ecuador, namely O. jeanmarctouzeti sp. n. from the Neotropical blunt-headed treesnake Imantodes cenchoa (Linnaeus), O. barraganae sp. n. from the beautiful calico snake Oxyrhopus formosus (Wied-Neuwied) and O. velascoae sp. n. from the forest flame snake Oxyrhopus petolarius (Linnaeus). The new species are characterised by type 1 uterine development, the number and distribution of testes, the size of the scolex and other metric features. As no molecular data are available on the specimens collected more than 35 years ago, the phylogenetic relationships of the individual taxa are not known.

来自厄瓜多尔双齿蛇（Squamata: Colubridae）的 Ophiotaenia La Rue, 1911（绦虫纲：Proteocephalidae）的三个新种。

人们对新热带爬行动物的寄生虫动物群知之甚少，在这些宿主身上描述的寄生虫数量似乎与这一动物地理区域的实际物种多样性并不相符。这也适用于蛋白头绦虫等绦虫，这些绦虫很少在爬行动物中发现，而且对爬行动物宿主具有严格的特异性。本文描述了 Ophiotaenia La Rue, 1911 的三个新种，它们分别来自厄瓜多尔的三个双齿蛇物种（有鳞目：颊蛇科），即来自新热带钝头蛇的 O. jeanmarctouzeti sp.O. barraganae sp. n. 来自美丽花蛇 Oxyrhopus formosus (Wied-Neuwied)，O. velascoae sp. n. 来自森林火焰蛇 Oxyrhopus petolarius (Linnaeus)。这些新物种的特征包括子宫发育类型 1、睾丸的数量和分布、鞘状突的大小以及其他度量特征。由于没有 35 年前采集的标本的分子数据，因此尚不清楚各个类群的系统发育关系。

期刊介绍： FOLIA PARASITOLOGICA, issued in online versions, is an international journal that covers the whole field of general, systematic, ecological and experimental parasitology. It publishes original research papers, research notes and review articles. Contributions from all branches of animal parasitology, such as morphology, taxonomy, biology, biochemistry, physiology, immunology, molecular biology and evolution of parasites, and host-parasite relationships, are eligible. Novelty and importance in the international (not local or regional) context are required. New geographical records of parasites, records of new hosts, regional parasite and/or host surveys (if they constitute the principal substance of manuscript), local/regional prevalence surveys of diseases, local/regional studies on epidemiology of well known diseases and of parasite impact on human/animal health, case reports, routine clinical studies and testing of established diagnostic or treatment procedures, will not be considered. One species description will also not be considered unless they include more general information, such as new diagnostic characters, host-parasite associations, phylogenetic implications, etc. Manuscripts found suitable on submission will be reviewed by at least two reviewers.
