Crucirostra bifasciata C.L. Brehm

Crucirostra bifasciata C.L. Brehm, 1827a: 85 (Thüringer Wald) .

Now Loxia leucoptera bifasciata (C.L. Brehm, 1827) . See Hartert, 1904a: 123–124; Hartert, 1918: 13; Vaurie, 1959: 652–653; Howell et al., 1986: 293; Dickinson, 2003: 756; and Clement, 2010: 604–605.

LECTOTYPE: AMNH 457068, male, collected in Thüringer Forest (5 Thüringer Wald, as on label), Germany, on 10 August 1826. From the C.L. Brehm Collection via the Rothschild Collection.

COMMENTS: In the original description, Brehm described in great detail the adult male, immature male, female, and young, without saying exactly how many specimens he examined, except for two males molting into adult plumage, the description of one of these having been sent to him by Gourcy-Droitaumont. Four Brehm specimens were cataloged as bifasciata at AMNH. Hartert (1918: 13) listed the type as the single male specimen collected on 10 August 1826, thereby designating it the lectotype. Two of the three additional specimens are paralectotypes: AMNH 457069, male, and AMNH 457070, female, collected in the Thüringer Forest on 12 August 1826. The fourth specimen, AMNH 457071, also collected in 1826, was exchanged to ZFMK and may be a paralectotype if it was labeled bifasciata by Brehm.

Brehm (1827b: cols. 714–716) discussed bifasciata and later, he (Brehm, 1853: 245– 248, fig. no. 16 on unnumbered plate, opp. p. 182) provided a summary of his information on this form. The reverse of Brehm’s label of the lectotype is numbered ‘‘No. 16’’ in Brehm’s hand.
