I should have highlighted this section:
“However, based on all available evidence, we propose that E. erythrogaster complex is composed of 17 species figure 5; see also the electronic supplementary material for evaluation of species status in cases of conflicting data): Philippine pitta E. erythrogaster, with subspecies erythrogaster and propinqua (the latter including ‘thompsoni’); (ii) Talaud pitta inspeculata; (iii) Sulu pitta E. yairocho;(iv) Sula pitta E. dohertyi; Siao pitta E. palliceps; (vi) Sangihe pitta E. caeruleitorques; vii) Sulawesi pitta E. celebensis; (viii) Buru pitta E. rubrinucha; Seram pitta E. piroensis; (x) Louisiade pitta E. meeki; Moluccan pitta E. rufiventris, with subspecies rufiventris including ‘obiensis’), cyanonota and bernsteini; (xii) New Ireland pitta E. novaehibernicae, with subspecies extima and novaehibernicae); (xiii) New Britain pitta E. gazellae; (xiv) Tabar pitta E. splendida; (xv) Habenicht’s pitta E. habenichti; (xvi) D’Entrecasteaux pitta E. finschii; and (xvii) Papuan pitta E. macklotii, with subspecies macklotii (including ‘aruensis’ and ‘kuehni’), loriae (including ‘oblita’) and digglesi.”

The spatio-temporal colonization and diversification across the Indo-Pacific by a ‘great speciator’ (Aves, Erythropitta erythrogaster). Proc. R. Soc.

The Indo-Pacific region has arguably been the most important area for the formulation of theories about biogeography and speciation, but modern studies of the tempo, mode and magnitude of diversification across this region are scarce. We study the biogeographic history and characterize levels of diversification in the wide-ranging passerine bird Erythropitta erythrogaster using molecular, phylogeographic and population genetics methods, as well as morphometric and plumage analyses. Our results suggest that E. erythrogaster colonized the Indo-Pacific during the Pleistocene in an eastward direction following a stepping stone pathway, and that sea-level fluctuations during the Pleistocene may have promoted gene flow only locally. A molecular species delimitation test suggests that several allopatric island populations of E. erythrogaster may be regarded as species. Most of these putative new species are further characterized by diagnostic differences in plumage. Our study reconfirms the E. erythrogaster complex as a ‘great speciator’: it represents a complex of up to 17 allopatrically distributed, reciprocally monophyletic and/or morphologically diagnosable species that originated during the Pleistocene. Our results support the view that observed latitudinal gradients of genetic divergence among avian sister species may have been affected by incomplete knowledge of taxonomic limits in tropical bird species. ===============================
