Hypocnemis myotherina sororia Hellmayr, 1910: 358

(Calama).

Now Myrmoborus myotherinus “ sororia ” (Hellmayr,

1910). See Haffer and Fitzpatrick, 1985: 156.

HOLOTYPE: AMNH 491839 , adult female, collect- ed at Calama , 08°03′S, 62°53′W, right bank of upper Rio Madeira , Rondônia, Brazil, on 3 July 1907, by Wilhelm Hoffmanns (no. 158). From the Rothschild Collection.

COMMENTS: In the original description, the sex of the holotype was correctly given as adult female ; however, in his Rothschild type list, Hartert (1922: 395) incorrectly listed it as a male.

Haffer and Fitzpatrick (1985: 156) considered M. m. “ sororia ” intermediate between M. m. myotherinus and M. m. ochrolaema.
