Horornis diphone iwootoensis Momiyama

Horornis diphone iwootoensis Momiyama, 1927: 146 (Motoyama, Sulphur Island, Volcano Islands).

Now Cettia diphone diphone (Kittlitz, 1831) . See Committee for Check-List of Japanese Birds, 2000: 218, 307–308, and Morioka et al., 2005: 55.

HOLOTYPE: AMNH 785098 , adult male, collected on Iwo Jima (5 Sulphur Island ), Iwo Islands (5 Volcano Islands), 24.47N, 141.19E ( Morioka et al., 2005: 150), Japan, on 20 December 1924, by T.T. Momiyama (no. 1297) and Senzo Awoki. From the Athenaei Ornithologici Momiyamici (no. 24.0457).

COMMENTS: Approximately 1000 specimens from the Momiyama Collection were acquired by AMNH in 1963, including the holotype of H.d. iwootoensis, which lay unrecognized in the general collection until recently. Although Momiyama cited specimen number ‘‘1297’’ in the original description and noted that he had eight males and two females from Sulphur Island , he did not give the year of collection. At least one additional specimen in AMNH is a paratype: AMNH 785100 , female, collected on 18 December 1924 (Momiyama nos. 1287 and 24.0452). Two additional specimens were collected early enough and may also be paratypes: AMNH 785099 , adult male, 28 November 1925 (1985, 25.0510) ; and AMNH 785101 , adult female, 13 November 1925 (1979, 25.0509) .
