本文记述了1915年寄生于鸟类科(Formicariidae、Thraupidae、Tyrannidae、Trolobdytidae和Icteridae)成员的Myrside a Watston的10个新种。它们和它们的类型寄主均为毛叶蜂M.isacantha sp.N.ex Chamaeza nobilis Gould，圆顶小蜂M.nobila sp.前福氏吸虫N.ex formicarius Colma Boddaert(蚁科)；N.ex Lanio fulvus(Boddaert)，M.brasiliens sp.N.ex Tangara Chilens(Vigors)，M.saviti sp.N.ex Tangara schrankii(Spix)(Thraupidae)，M.rodriguesae sp.N.ex Cnipodectes subbrunneus(Sclater)，M.cnemotriccola sp.N.ex Cnemotriccus fuscatus(Wed-Neuwied)，M.lathrotriccola sp.N.ex Lathrotriccus euleri(Cabanis)(Tyrannidae)，M.faccioae sp.N.ex Cyphorhinus arada Transstream vialis(Todd)和M.lamprosaricola sp.黄蜂科(N.ex Lamprosar tanagrinus(Spix))其中两个新种记述自鸟类蚁科，以前只有一个记述种，另一个寄主新记录为肉桂分枝杆菌，2005 ex Attila Citriniventris Sclater。对这些和其他新热带桃金莲属物种的线粒体细胞色素氧化酶I序列的分析提供了对它们系统发育关系的评估，并表明所有这些新描述的物种在遗传上都是不同的。考虑到已知的潜在宿主的多样性和Myrside a物种的典型寄主专一性，我们还通过估计巴西未命名Myrside a物种的潜在数量来结合这些描述。我们的估计表明，巴西桃金娘的物种多样性可能比巴西已知的已描述的桃金娘物种的数量大一个数量级以上，这突显了未来对这种巨大多样的体外寄生虫属进行研究的必要性。
Ten new species of Myrsidea Waterston, 1915 parasitic on members of the avian families Formicariidae, Thraupidae, Tyrannidae, Troglodytidae and Icteridae are described herein. They and their type hosts are M. isacantha sp. n. ex Chamaeza nobilis Gould, M. circumsternata sp. n. ex Formicarius colma Boddaert (Formicariidae); M. cacioppoi sp. n. ex Lanio fulvus (Boddaert), M. brasiliensis sp. n. ex Tangara chilensis (Vigors), M. saviti sp. n. ex Tangara schrankii (Spix) (Thraupidae), M. rodriguesae sp. n. ex Cnipodectes subbrunneus (Sclater), M. cnemotriccola sp. n. ex Cnemotriccus fuscatus (Wied-Neuwied), M. lathrotriccola sp. n. ex Lathrotriccus euleri (Cabanis) (Tyrannidae), M. faccioae sp. n. ex Cyphorhinus arada transfluvialis (Todd) (Troglodytidae), and M. lampropsaricola sp. n. ex Lampropsar tanagrinus (Spix) (Icteridae). Among these are two new Myrsidea species described from the avian family Formicariidae, which previously had only a single described Myrsidea species, and a new host record for M. cinnamomei Dalgleish et Price, 2005 ex Attila citriniventris Sclater. Analysis of mitochondrial cytochrome oxidase I sequences for these and other neotropical Myrsidea species provides an assessment of their phylogenetic relationships and indicates that all of these newly described species are genetically distinct. We also put these descriptions into context by estimating the potential number of unnamed Myrsidea species in Brazil, given the known diversity of potential hosts and typical levels of host specificity for Myrsidea species. Our estimate indicates that Brazilian Myrsidea species diversity is likely more than an order of magnitude greater than the number of described Myrsidea species known from Brazil, highlighting the need for future work on this megadiverse ectoparasite genus.
