本文记述了新热带地区雀形目鸟类(雀形目：红雀科、斑虱科、斑虱科)的11种跳蚤。文中记述并图示了巴拉圭寄主的三新种：桃金龟科新种ex Sinalis Huang eola、桃金龟科新种ex Habia ruica和桃金龟科新种ex Thraupis sayaca。关于种内形态变异性、寄主关联性和地理分布的新数据包括另外五个以前已知的Myrside a种：Myrside a coronatae、M.light tae、M.Rufi、M.Seminuda和M.Viaceae。由于缺乏足够的资料，另有三个种仅在属的水平上被记录。为了评估桃金娘种群间的相对遗传差异，对其线粒体细胞色素氧化酶I(COI)基因379bp的部分序列进行了测序。讨论了种内和种间序列差异作为物种边界预测因子在该巨型多样性属的分类学中的应用。
Eleven species of lice of the genus Myrsidea Waterston, 1915 (Phthiraptera: Menoponidae) from passerine birds (Passeriformes: Cardinalidae, Fringillidae, Thraupidae) in the Neotropical Region are recorded and discussed. They include three new species with hosts in the family Thraupidae from Paraguay, which are described and illustrated: Myrsidea flaveolae new species ex Sicalis flaveola , Myrsidea habiae new species ex Habia rubica , and Myrsidea sayacae new species ex Thraupis sayaca . Five other previously known Myrsidea species are included with new data on intraspecific morphological variability, hosts associations and geographical distribution, as follows: Myrsidea coronatae , M. lightae , M. rufi , M. seminuda , and M. violaceae . Three further species are recorded at genus level only due to lack of adequate material. A 379 bp portion of the mitochondrial cytochrome oxidase I ( COI ) gene was sequenced in order to assess relative genetic divergence among Myrsidea populations. The application of intra- and interspecific sequence divergences as predictor of species boundaries in the taxonomy of this megadiverse genus is discussed.
