Corvus coronoides hainanus Stresemann

Corvus coronoides hainanus Stresemann, 1916: 286 (Hoihow (Hainan)).

Now Corvus macrorhynchos colonorum Swinhoe, 1864 . See Hartert, 1919: 127; 1929a: 48–54; Blake and Vaurie, 1962: 274; Cheng, 1987: 555; Madge and Burn, 1994: 162–164; Dickinson et al., 2004c: 96–102; 2004b: 124; and dos Anjos, 2009: 631.

LECTOTYPE: AMNH 674372, adult male, collected at Hai-k’ou (= Hoihow), 20.50N, 110.25E (Times Atlas), Hai-nan Tao (= Hainan) Island, China, on 15 March 1902, by Zensaku Katsumata. From the Rothschild Collection.

COMMENTS: In the original description, Stresemann designated as the type of hainanus the adult male specimen collected by Katsumata at Hoihow on 15 March 1902 and gave measurements for 15 specimens without indicating those of the type specimen. There are two adult male specimens collected at Hoihow on 15 March 1902, and Hartert’s (1919: 127) listing of the type of this form did not distinguish between the two specimens. AMNH 674372 is clearly Stresemann’s intended type, as it bears a Rothschild type label and was cataloged as the type at AMNH. In order to remove the ambiguity, I hereby designate AMNH 674372 the lectotype of Corvus coronoides hainanus .

The 14 paralectotypes are: Hai-k’ou, AMNH 674373–674381, five males, four females, 2–17 March 1902, 10–11 March 1903; Liudon, AMNH 674382–674386, four males, one female, 9–13 March 1903, all collected by Katsumata.

Most recent authors consider hainanus a synonym of colonorum in species C. macrorhynchos .
