DEFINITIONS

PODICEPS
(Podicipedidae; Ϯ Great Crested Grebe P. cristatus) L. podex, podicis  vent, anus; pes, pedis  foot  < Gr. πους pous, ποδος podos  foot; the legs of the Great Crested Grebe are set back to the rear of the body, giving rise to a former name “Arsefoot” which may have influenced Latham's coinage; "GENUS LXXIX.  GREBE.  PODICEPS, (Colymbus, Lin.)" (Latham 1787); "Podiceps Latham, 1787, General Synop. Birds, Suppl., p. 294. Type, by subsequent designation (G. R. Gray, 1840, List Gen. Birds, p. 76) and under plenary powers of the International Commission on Zoological Nomenclature, 1956, Opin. Decl. Rend., 13, p. 4, Colymbus cristatus Linnaeus." (Storer in Peters 1979, 1, 2nd. ed., 148).

● "*4.  Ard. podiceps, Bp. Mus. Paris. a Berniero 1834.  ex Madagascar." (Bonaparte 1855); probably alluding to the vaguely grebe-like plumage, slender bill and short tail of the Little Bittern (subsp. Ixobrychus minutus).
● "68. COLYMBUS.  ...  Podiceps.  4. C. pedibus lobatis, corpore fusco, rostro fascia sesqui altera.  Podiceps minor, rostro vario. Catesb. car. 1. p. 91. t. 91.  Habitat in America septentrionali." (Linnaeus 1758) (Podilymbus).

gallardoi / gallardoorum
Dr Ángel Gallardo (1867-1934) Argentinian civil engineer, politician, zoologist, and his grandson Prof. Dr José María Alfonso Félix Gallardo (1925-1994) Argentinian zoologist, both former Directors of Museo Argentino de Ciencias Naturales 'Bernadino Rivadavia' (Björn Bergenholtz and Laurent Raty in litt.).  The epithet gallardoorum appears to be a manuscript name, used to reflect the dual dedication (Podiceps).
