Abstract
<p><p id="x-x-sp015">Ground-doves represent an insular bird radiation distributed across the Indo-Pacific. The radiation comprises sixteen extant species, two species believed to be extinct and six species known to be extinct. In the present study, we present a molecular phylogeny for all sixteen extant species, based on two mitochondrial markers. We demonstrate that the <em>Gallicolumba</em> as currently circumscribed is not monophyletic and recommend reinstalling the name <em>Alopecoenas</em> for a monophyletic radiation comprising ten extant species, distributed in New Guinea, the Lesser Sundas and Oceania. <em>Gallicolumba</em> remains the name for six species confined to New Guinea the Philippines and Sulawesi. Although our phylogenetic analyses fail to support a single origin for the remaining <em>Gallicolumba</em> species, we suspect that the addition of nuclear sequence data may alter this result. <p id="x-x-sp020">Because a number of ground-dove taxa have gone extinct, it is difficult to assess biogeographical patterns. However, the <em>Alopecoenas</em> clade has clearly colonized many remote oceanic islands rather recently, with several significant water crossings. The <em>Gallicolumba</em> radiation(s), on the other hand, is significantly older and it is possible that diversification within that group may in part have been shaped by plate tectonics and corresponding re-arrangements of land masses within the Philippine and Sulawesi region.</p>
