TL;DR: New data is provided on systematics and host associations of feather mites of the subfamily Proctophyllodinae recorded on passerine birds in Costa Rica and the female of Anisophyllodes pipromorphae Atyeo, 1967, previously known from two forms of males only, is described for the first time.
Abstract: The paper provides new data on systematics and host associations of feather mites of the subfamily Proctophyllodinae (Astigmata: Proctophyllodidae) recorded on passerine birds (Passeriformes) in Costa Rica. A total of 25 proctophyllodine species of six genera have been recorded, of which 19 new species are described: Anisophyllodes cuneiformis sp. n. from Sittasomus griseicapillus (Vieillot) (Furnariidae), Atrichophyllodes latilobus sp. n. from Hylophylax naevioides (Lafresnaye) (Thamnophilidae), Nycteridocaulus attila sp. n. from Attila spadiceus (Gmelin, JF) (Tyrannidae), N. hylophylax sp. n. from Hylophylax naevioides (Lafresnaye) (Thamnophilidae), N. ketourus sp. n. from Thryophilus rufalbus (Lafresnaye) (Troglodytidae), N. leptopogoni sp. n. from Leptopogon superciliaris Tschudi (Tyrannidae), N. myiobius sp. n. from Myiobius sulphureipygius (Sclater, PL) (Tyrannidae), N. myioborus sp. n. from Myioborus miniatus (Swainson) (Parulidae), N. platyrinchi sp. n. from Platyrinchus cancrominus Sclater, PL and Salvin (Tyrannidae), Platyacarus caulifer sp. n. from Glyphorynchus spirurus (Vieillot) (Furnariidae), Pl. dendrocinclae sp. n. from Dendrocincla homochroa (Scalter, PL) (Furnariidae), Pl. dendrocolapti sp. n. and Pl. picumnus sp. n. from Dendrocolaptes picumnus Lichtenstein, MHK (Furnariidae), Pl. sclerurus sp. n. from Sclerurus mexicanus Sclater, PL (Furnariidae), Proctophyllodes arremoni sp. n. from Arremon brunneinucha (Lafresnaye) (Emberizidae), Pr. euphoniae sp. n. from Euphonia hirundinacea Bonaparte (Fringillidae), Pr. vesicularis sp. n. from E. anneae Cassin (Fringillidae), Pr. parkesiae sp. n. from Parkesia motacilla (Vieillot) (Parulidae), and Pr. strictophyllus sp. n. from Coereba flaveola (Linnaeus) (Thraupidae). The female of Anisophyllodes pipromorphae Atyeo, 1967, previously known from two forms of males only, is described for the first time. Five new host associations are recorded for the following mites: Anisophyllodes pipromorphae from Mionectes olivaceus Lawrence (Tyrannidae), Diproctophyllodes dielytra (Trouessart, 1885) from Chiroxiphia linearis (Bonaparte) and Corapipo altera Hellmayr (Pipridae), Nycteridocaulus pectinatus Atyeo, 1966 from Tolmomyias sulphurescens (von Spix) (Tyrannidae), and Proctophyllodes thraupis Atyeo and Braasch, 1966 from Tangara icterocephala (Bonaparte) (Thraupidae). Two species, Proctophyllodes habiae Atyeo and Braasch, 1966 from Habia rubica (Vieillot) (Cardinalidae) and Platyacarus sittasomi Hernandes et al. , 2007 from Sittasomus griseicapillus (Vieillot) (Furnariidae), are recorded in Costa Rica for the first time. New diagnoses and keys to all currently known species are provided for the genera Anisophyllodes Atyeo, 1967, Atrichophyllodes Hernandes et al. , 2007, Nycteridocaulus Atyeo, 1966, and Platyacarus Kudon, 1982. Two new species groups, caulifer and minor, are established within the genus Platyacarus . The history of taxonomic investigations of proctophyllodine feather mites is briefly presented. We summarize host associations with passerine birds of the New World for these proctophyllodine genera and species, excluding the genus Proctophyllodes .

TL;DR: A well‐resolved phylogeny based on DNA sequences from three nuclear introns for 128 taxa is presented, confirming much of the overall picture of Tyrannidae relationships, and also identifying several novel relationships.
Abstract: Ohlson, J., Fjeldsa J. & Ericson, P. G. P. (2008). Tyrant flycatchers coming out in the open: phylogeny and ecological radiation of Tyrannidae (Aves, Passeriformes). — Zoologica Scripta, 37 , 315–335. Tyrant flycatchers constitute a substantial component of the land bird fauna in all South American habitats. Past interpretations of the morphological and ecological evolution in the group have been hampered by the lack of a well-resolved hypothesis of their phylogenetic interrelationships. Here, we present a well-resolved phylogeny based on DNA sequences from three nuclear introns for 128 taxa. Our results confirm much of the overall picture of Tyrannidae relationships, and also identify several novel relationships. The genera Onychorhynchus , Myiobius and Terenotriccus are placed outside Tyrannidae and may be more closely related to Tityridae. Tyrannidae consists of two main lineages. An expanded pipromorphine clade includes flatbills, tody-tyrants and antpipits, and also Phylloscartes and Pogonotriccus . The spadebills, Neopipo and Tachuris are their closest relatives. The remainder of the tyrant flycatchers forms a well-supported clade, subdivided in two large subclades, which differ consistently in foraging behaviour, the perch-gleaning elaeniines and the sallying myiarchines, tyrannines and fluvicolines. A third clade is formed by the genera Myiotriccus , Pyrrhomyias , Hirundinea and three species currently placed in Myiophobus . Ancestral habitat reconstruction and divergence date estimation suggest that early divergence events in Tyrannida took place in a humid forest environment during the Oligocene. Large-scale diversification in open habitats is confined to the clade consisting of the elaeniines, myiarchines, tyrannines and fluvicolines. This radiation correlates in time to the expansion of semi-open and open habitats from the mid-Miocene ( c . 15 Mya) onwards. The pipromorphine, elaeniine and myiarchine–tyrannine–fluvicoline clades each employ distinct foraging strategies (upward striking, perch-gleaning and sallying, respectively), but the degree of diversity in morphology and microhabitat exploitation is markedly different between these clades. While the pipromorphines and elaeniines each are remarkably homogenous in morphology and exploit a restricted range of microhabitats, the myiarchine–tyrannine–fluvicoline clade is more diverse in these respects. This greater ecological diversity, especially as manifested in their success in colonizing a wider spectrum of open habitats, appears to be connected to a greater adaptive flexibility of the search-and-sally foraging behaviour.

TL;DR: The results demonstrate that Neopipo cinnamomea is not a manakin, but a member of the Myiophobicus group of tyrannids, which includes Myiophobus, Myiobius (including Terenotriccus erythrurus), Pyrrhomyias, and Hirundinea (Lanyon 1986, 1988a).
Abstract: A cladistic analysis of 14 binary morphological and nest architecture characters was conducted to investigate the relationship of Neopipo cinnamomea, formerly placed in the manakins (Pipridae), to the Empidonax assemblage of tyrant flycatchers (Tyrannidae; Lanyon 1986, 1988a). The results demonstrate that Neopipo cinnamomea is not a manakin, but a member of the Myiophobus group of tyrannids, which includes Myiophobus, Myiobius (including Terenotriccus erythrurus), Pyrrhomyias, and Hirundinea (Lanyon 1986, 1988a). Detailed illustrations and formal descriptions of the syringeal morphology of Neopipo cinnamomea and related genera are presented. Two alternative, maximally parsimonious phylogenetic hypotheses were identified (length = 20; Consistency Index = 0.70). In both hypotheses, Myiophobus is the sister group to the other five genera, and the monophyly of Myiobius including M. erythrurus is supported. The two alternative hypotheses differ in the hypothesized relationships among Neopipo, Pyrrhomyias and Hirundinea. In the first, Neopipo and Pyrrhomyias constitute a monophyletic group, and Hirundinea is its sister group. In the second, Hirundinea and Pyrrhomyias form a clade with Neopipo as its sister group. These findings strongly confirm that Neopipo is not a member of the Pipridae. It is recommended that Neopipo cinnamomea be referred to as the Cinnamon Tyrant, and that it be included in the Myiophobus group within the Empidonax assemblage of the Tyrannidae. The hypothesis that Neopipo cinnamomea is strikingly convergent with the tyrannid Myiobius erythrurus is falsified. Some similarities in plumage between these species are apparently homologous traits that evolved early in the radiation of the Myiophobus group.
