Abstract

During a survey of helminth parasites of the brown ground snake, Atractus major Boulenger, 1894 (Serpentes: Dipsadidae) from Moyobamba, region of San Martin (northeastern Peru), a new species of Glossidiella Travassos, 1927 (Plagiorchiida: Plagiorchiidae) was found and is described herein based on morphological and ultrastructural data. The digeneans found in the lung were measured and drawings were made with a drawing tube. The ultrastructure was studied using scanning electron microscope. Glossidiella peruensis sp. nov. is easily distinguished from the typeand only species of the genus, Glossidiella ornata Travassos, 1927, by having an oblong cirrus sac (claviform in G. ornata), distinctly ovate testes (rounded testes in G. ornata) and button-like papillae on the dorsal edge of the oral sucker region (absent in G. ornata). In addition, G. peruensis sp. nov. differs from G. ornata by possessing a longer distance between testes and substantially wider oral and ventral suckers. This is the first time that a species of digenean is described and reported parasitizing snakes in Peru.

在对秘鲁东北部圣马丁地区Moyobamba地区褐地蛇(Atractus major Boulenger, 1894)的寄生虫进行调查时，发现了一新种Glossidiella Travassos, 1927(斜纹蛇目:斜纹蛇科)，并根据其形态和显微结构资料进行了描述。测量肺内发现的地沟菌，并用绘图管绘图。用扫描电镜观察其超微结构。由于其长圆形卷云囊(棒状)、明显卵形睾丸(圆形睾丸)和口吸盘区背缘的钮扣状乳头(无)，秘鲁绿舌虫很容易与该属的典型种(1927年的唯一种)Glossidiella ornata Travassos区分。此外，秘鲁蠓与鸟蠓的不同之处在于睾丸之间的距离较长，口腔和腹部吸盘较宽。这是秘鲁第一次描述和报道一种地根虫寄生在蛇身上。
