DEFINITIONS

LEIOTHLYPIS
(Parulidae; Ϯ Tennessee Warbler L. peregrina) Gr. λειος leios  plain; θλυπις thlupis  unknown small bird. In ornithology thlypis signifies either a thin-billed tanager or, as in this case, a parulid warbler. "No generic name has been proposed for the clade formed by the six 'plain' species ...  Therefore, I propose a new genus taxon for this clade.  Leiothlypis, gen. nov. ...  Differs from Oreothlypis ...in plain plumage without black markings on the head, upperparts and underparts. Differs from Vermivora ...  in the plain head and wing pattern ...  The name Leiothlypis is derived from the Greek λειος, meaning plain, and the Greek θλυπις, the name of a kind of finch said to be found in the codices of Aristoteles (Stejneger 1884). The gender of the name Leiothlypis is feminine" (Sangster 2008).
Var. Leiothylypis.
