Ducula harrisoni Wragg & Worthy, 2006:130
Henderson imperial pigeon, Harrison’s imperial pigeon, Henderson Island imperial-pigeon, Henderson ducula pigeon (Wragg & Weisler, 1994:61; Wragg, 1995:407)
Taxonomy & Nomenclature
The existence of an undescribed species of Ducula was reported by (Wragg & Weisler, 1994:64), but not described until 2006 (Wragg & Worthy, 2006). Steadman & Olson (1985:6193-6194) had earlier mentioned the existence of two Ducula sp. on Henderson Island but had considered them to be from extant species, or in the second instance, and which is in fact probably referrable to Ducula harrisoni, that it belonged to a species closely allied to D. galeata. However, Steadman and Olson (1985) did not specifically state that their second species was probably an undescribed species, almost certainly due to a lack of diagnostic material (which has now been excavated).
Bourne & David (1986:302) may have suggested the existence of what is now known as D. harrisoni, thus predating (Wragg & Weisler, 1994) by 8 years, however I have not viewed that paper so I cannot draw any firm conclusion at this time.
