Conopoderas caffra idae Murphy and Mathews

Conopoderas caffra idae Murphy and Mathews, 1928: 15 (Huahuna Island, Marquesas Group).

Now Acrocephalus percernis idae ( Murphy and Mathews, 1928) . See Watson et al., 1986a: 71, del Hoyo et al., 2006: 630, Cibois et al., 2007, and Cibois et al., 2008.

HOLOTYPE: AMNH 195504 , adult male, collected on Ua Huka (5 Huahuna) Island, 08.55S, 139.32W (Times Atlas), Marquesas Islands, French Polynesia, on 9 November 1922, by Rollo H. Beck on the Whitney South Sea Expedition (no. 5984).

COMMENTS: The AMNH number of the holotype was given in the original description, and the type series included only ‘‘Specimens from Huahuna collected during November, 1922’’, thus excluding specimens collected in October 1921. The following specimens are paratypes: AMNH 195496– 195503 and 195505–195528. Of these, AMNH 195503 and 195509 were exchanged with the Rothschild Collection ; when this collection was purchased by AMNH, the specimens were renumbered AMNH 594917 and 594916, respectively. AMNH 195506 was exchanged to the ZMB in July 1936. I did not find AMNH 195496, 195505, 195510, 195511, or 195519 in the collection, and they may have been exchanged to other institutions without the catalog having been so marked .

Dickinson (2003: 585) listed idae as a subspecies of A. caffer and referenced other treatments. Recent mtDNA studies by Cibois et al. (2007) have indicated nonmonophyly of southern and northern Marquesan populations of Acrocephalus , and their proposed classification included the Ua Huka population in the species A. percernis .
