(Acrocephalidae; Ϯ Madagascar Brush-warbler N. typica) Gr. νησος nēsos  island (= Madagascar); ιλλας illas, ιλλαδος illados  thrush; "ELLISIA Hartlaub.  The genus Ellisia Hartlaub [1860] must give way to Ellisia Forbes and Goodsir [1840], for a group of Polypi.  As Thamnornis Milne-Edwards, type chloropetoides, appears to be sufficiently distinct for generic separation, a new name is necessary for the species of Ellisia proper; and Nesillas, from νησος, insula, and ιλλας, turdus, is proposed, the type being Ellisia typica Hartlaub." (Oberholser 1899).
Synon. Ellisia.
