Cairaella henrii gen. n., sp. n. (Proteocephalidea: Proteocephalinae) is described from the intestine of Norops trachyderma (Cope) (Polychrotidae) from San Pablo de Kantesiya in Ecuador. The new genus differs from the 12 other known genera of the Proteocephalinae (and all other proteocephalidean genera) by the presence of a dense network of osmoregulatory canals situated in the cortex and by the morphology of the scolex which is flattened dorsoventrally, with elongated deeply embedded suckers possessing a well-developed circular musculature situated in the anterolateral region, and by eggs with a three-layered embryophore possessing small outgrowths on its external surface. Ophiotaenia nicoleae sp. n. is described from the intestine of Thecadactylus rapicauda (Houttuyn) (Gekkonidae) from San Pablo de Kantesiya in Ecuador. This new species is characterised by the testes arranged in two fields, numbering 142-204, the cirrus-sac length representing 21-33% of proglottis width, the genital pore situated in the middle of the proglottis or slightly anteriorly, and the ovary width representing 68-88% of proglottis width. It differs from 20 of 27 Ophiotaenia species parasitic in New World reptiles by the presence of an apical organ and from the remaining species by one to several other morphological characters, such as the number of testes, diameter and shape of the scolex, position of ventral and dorsal osmoregulatory canals, or the presence of a vaginal sphincter. Both taxa represent the first record of proteocephalidean tapeworms in polychrotid and gekkonid lizards, respectively.
亨利凯拉绦虫属(Cairaella),新属,新种(原头科:原头亚科),采自厄瓜多尔圣巴勃罗德坎泰西亚的糙皮变色蜥(Norops trachyderma)(变色蜥科)的肠道。该新属与原头亚科的其他12个已知属(以及所有其他原头科属)不同,其皮层有密集的渗透调节管网络,头节形态为背腹扁平,有细长且深深嵌入的吸盘,吸盘前外侧区域有发育良好的环形肌肉组织,卵有三层胚膜,胚膜外表面有小突起。尼科莱奥菲绦虫(Ophiotaenia nicoleae),新种,采自厄瓜多尔圣巴勃罗德坎泰西亚的环尾蜥(Thecadactylus rapicauda)(壁虎科)的肠道。这个新种的特征是睾丸排列成两个区域,数量为142 - 204个,阴茎囊长度占节片宽度的21 - 33%,生殖孔位于节片中部或稍前方,卵巢宽度占节片宽度的68 - 88%。它与寄生在新大陆爬行动物身上的27种奥菲绦虫中的20种不同之处在于有顶器,与其余物种的不同之处在于有一个或几个其他形态特征,如睾丸数量、头节直径和形状、腹侧和背侧渗透调节管的位置,或是否有阴道括约肌。这两个分类单元分别代表了原头科绦虫在变色蜥科和壁虎科蜥蜴中的首次记录。
