Abstract

Pentastomida are lung parasites of a variety of hosts, mainly reptiles. Raillietiella is the genus with the largest number of species, whose taxonomic identification is still largely based on morphological data alone. In this classification, differences divide the genus into morphotypic groups. The Raillietiella parasites of insectivorous lizards, for example, are divided into "Group I" with species with hooks with sharp tips and "Group II" with posterior hooks with blunt tips. In the present work, we used molecular analysis to infer the morphological variation in hooks and size of specimens of Raillietiella mottae, parasites of several species of insectivorous lizards. Our results demonstrate that morphological differences comprise a phenotypic plasticity of a single species, whose variation is associated with host species, with females being larger and with hooks with blunt tips in nocturnal geckos and smaller ones with sharp tips in diurnal insectivorous lizards of different species, sizes, and habitats.

重新描述食虫蜥蜴的寄生虫 Raillietiella mottae(Raillietiellidae: Pentastomida):分子数据揭示的表型可塑性。
五触角虫是多种宿主(主要是爬行动物)的肺部寄生虫。五触角虫属是物种数量最多的属,其分类鉴定仍主要仅基于形态学数据。在这种分类方法中,不同之处在于将该属分为不同的形态组。例如,食虫蜥蜴的 Raillietiella 寄生虫被分为 "I 组 "和 "II 组","I 组 "物种的钩尖锋利,"II 组 "物种的后钩尖钝。在本研究中,我们利用分子分析推断了寄生于几种食虫蜥蜴的Raillietiella mottae标本的钩和大小的形态差异。我们的研究结果表明,形态差异构成了单一物种的表型可塑性,其变化与宿主物种有关,在不同物种、大小和栖息地的夜行性食虫蜥蜴中,雌性的钩体较大且钩尖较钝,而在昼行性食虫蜥蜴中,雌性的钩体较小且钩尖较尖。
