Ectoparasites were collected from seven puma (Puma concolor) and seven jaguar (Panthera onca) live-captures (each representing six different animals) in the Paraguayan Chaco from 2002 to 2004. The same five species of ectoparasites were recovered from both host species: the flea, Pulex simulans (total on both hosts combined=30 male, 49 female), and the ticks, Amblyomma cajennense (1 male, 4 female, 46 nymphs, 241 larvae), Amblyomma parvum (42 male, 25 female), Amblyomma tigrinum (1 male, 7 female, 34 larvae) and Amblyomma triste (4 male). There were no statistical differences between the prevalences (percent of hosts infested) for any of these ectoparasite species between the two host species, and only P. simulans showed a significantly higher mean intensity (mean no. of each ectoparasite species per infested host) on one of the host species (jaguar). Clearly, these two large carnivores share similar ectoparasite faunas in the Paraguayan Chaco. However, both carnivores occupy large geographical distributions in the New World and this study, combined with the few previous studies, suggests that their ectoparasite faunas differ slightly in different parts of their respective ranges.

Twenty-four species of chewing lice of the genus Myrsidea Waterston, 1915 (Phthiraptera: Menoponidae) from Neotrop- ical Suboscines (Passeriformes: Formicariidae, Furnariidae, Pipridae, Thamnophilidae, Tityridae, Tyrannidae) are record- ed and discussed. They include: eight new species which are described and illustrated (Myrsidea capeki new species ex Chiroxiphia caudata; Myrsidea leptopogoni new species ex Leptopogon superciliaris; Myrsidea leucophthalmi new spe- cies ex Automolus leucophthalmus; Myrsidea pachyramphi new species ex Pachyramphus polychopterus; Myrsidea phi- lydori new species ex Philydor rufum; Myrsidea pyriglenae new species ex Pyriglena leucoptera; Myrsidea scleruri new species ex Sclerurus scansor and Myrsidea zuzanae new species ex Furnarius rufus), as well as nine previously known species with additional data on intraspecific morphological variability, host associations and geographical distribution (Myrsidea barbati Price, Hellenthal \& Dalgleish, 2005; Myrsidea dalgleishi Valim, Price \& Johnson, 2011; Myrsidea fla- viventris Price, Hellenthal \& Dalgleish, 2005; Myrsidea klimesi Sychra, 2006; Myrsidea meyi Valim, Price \& Johnson, 2011; Myrsidea oleaginei Price, Hellenthal \& Dalgleish, 2005; Myrsidea olivacei Price, Hellenthal \& Dalgleish, 2005; Myrsidea pitangi Price, Hellenthal \& Dalgleish, 2005 and Myrsidea spellmani Price, Johnson \& Dalgleish, 2008b). Seven 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 from seven species in order to assess relative genetic divergences among Myrsidea populations.

Eleven species of lice of the genus Myrsidea Waterston, 1915 (Phthiraptera: Menoponidae) from passerine birds (Passer- iformes: 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 morpholog- ical 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.

Two species of the chewing louse genus Ricinus are redescribed and illustrated: Ricinus dalgleishi Nelson, 1972 from Helmitheros vermivorum (Gmelin, 1789), a new host-louse association, and Ricinus tanagraephilus Eichler, 1956 from Euphonia laniirostris d\&$\#$39;Orbigny \& Lafresnaye, 1837. Also, new host-louse associations are recorded for Ricinus vireoen- sis Nelson, 1972 from Vireo pallens Salvin, 1863, and for females of an unidentified species of Ricinus sp. from Corytho- pis delalandi (Lesson, 1831), which are described and illustrated.
