gracilis

L. gracilis or gracilus  slender, elegant, slim, thin.
● “has many characters in common with the Ptilotis chrysotis ... and the Ptilotis similis ... but it differs from both in the greater slenderness of its form, in its diminutive size, and, especially from the former, in the uniform colouring of its throat and abdomen” (Gould 1866) (Microptilotis).
● ex “Gracile Goatsucker” of Latham 1801 (syn. Podargus strigoides).
