“…Discrepancies between mtDNA and existing taxonomy offer insights to a species’ biology not just reasons to question existing taxonomy (Funk and Omland 2003, Joseph and Wilke 2004, Omland et al 2006). We now consider how the taxonomic status of A. personatus and A. superciliosus should be re‐evaluated in light of their mtDNA polyphyly and which biogeographical mechanism(s) may have caused their speciation and presumably rapid phenotypic divergence, and when.…”

The white‐browed woodswallow Artamus superciliosus and masked woodswallow A. personatus (Passeriformes: Artamidae) are members of Australia's diverse arid‐ and semi‐arid zone avifauna. Widely sympatric and among Australia's relatively few obligate long‐distance temperate‐tropical migrants, the two are well differentiated morphologically but not ecologically and vocally. They are pair breeders unlike other Artamus species, which are at least facultative cooperative breeders. For these reasons they are an excellent case in which to use molecular data in integrative study of their evolution from ecological and biogeographical perspectives. We used mitochondrial DNA (mtDNA) to test whether they are each other's closest relatives, whether they evolved migration independently, whether they have molecular signatures of population expansions like some other Australian arid zone birds, and to estimate the timing of any inferred population expansions. Their mtDNAs are monophyletic with respect to other species of Artamus but polyphyletic with respect to each other. The two species appear not to have evolved migration independently of each other but their morphological and mtDNA evolution have been strongly decoupled. Some level of hybridization and introgression cannot be dismissed outright as being involved in their mtDNA polyphyly but incomplete sorting of their most recent common ancestor's mtDNA is a simpler explanation consistent with their ecology. Bayesian phylogenetic inference and analyses of diversity within the two species (n=77) with conventional diversity statistics, statistical parsimony, and tests for population expansion vs stability (Tajima's D, Fu's Fs and Ramos‐Onsin and Rozas's R2) all favour recent population increases. However, a non‐starlike network suggests expansion(s) relatively early in the Pleistocene. Repeated population bottlenecks corresponding with multiple peaks of Pleistocene aridity could explain our findings, which add a new dimension to accruing data on the effects of Pleistocene aridity on the Australian biota.

“…Increasing knowledge of flycatcher vocalizations has led to a redefinition of many species boundaries (Browning, ; Reynard, Garrido & Sutton, ; Zimmer & Whittaker, ) and has facilitated the discovery of undescribed species (Schulenberg & Parker, ; Coopmans & Krabbe, ; Álvarez Alonso & Whitney, ; Zimmer, Whittaker & Oren, ; Lane et al ., ). Similarly, molecular phylogenies of tyrannid genera have revealed deep divergences within so‐called species and paraphyletic or polyphyletic arrangements (Chesser, ; Joseph et al ., ; Joseph & Wilke, ; Rheindt, Christidis & Norman, , ; Rheindt, Norman & Christidis, , b; Rheindt et al ., ). A recurring theme has been the agreement of vocal and molecular data on new species boundaries where previous phenotypic data, the bedrock of traditional flycatcher classification, had disagreed (Rheindt et al ., ).…”

Polyphyletic arrangements in DNA phylogenies are often indicators of cryptic species diversity masked by erroneous taxonomic treatments that are frequently based on morphological data. Although mitochondrial (mt)DNA polyphyly is detected relatively rarely in phylogenetic studies, it has recently been found in a variety of tyrant‐flycatcher (Tyrannidae) groups. In the present study, we provide a DNA phylogeny for a mitochondrial and a nuclear locus with a complete species sampling in Zimmerius flycatchers, showing that the genus is characterized by multiple mtDNA polyphyly. Based on phylogenetic and life‐history information, we suggest the elevation of a number of taxa to species status, leading to a doubling of Zimmerius species‐level diversity compared to taxonomic treatments conducted before 2001. © 2013 The Linnean Society of London, Biological Journal of the Linnean Society, 2013, ●●, ●●–●●.

Tyrant-flycatchers (Tyrannidae) are a taxonomically confusing bird group containing a large degree of cryptic diversity that has only recently begun to be unraveled through the application of acoustic and molecular methods. We investigated all three subspecies of the Lesser Elaenia, Elaenia chiriquensis Lawrence, across their range using sound recordings as well as nuclear and mitochondrial markers. We show that two of the three subspecies, the nominate race from southern Central America and the widespread South American subspecies E. c. albivertex Pelzeln, have undergone very low levels of vocal and molecular differentiation across their fragmented range. In contrast, the isolated taxon E. c. brachyptera Berlepsch, endemic to the western and also, as recently shown, eastern slopes of the northern Andes, is phylogenetically and vocally distinct from other Lesser Elaenias, indicating that it constitutes a separate biological species.
