Key to Scientific Names in Ornithology
(syn. Ochthoeca Ϯ Tumbes Tyrant O. salvini) Tumbez (= Puerto Pizarro = Tumbes), north-western Peru (named for the Tumpis, an aboriginal people); "TUMBEZIA, new genus GENERIC CHARACTERS. -- A genus of the subfamily Tæniopterinæ with long tarsi and narrow bill, its depth at nostril equal to its height; rictal bristles inconspicuous reaching but little beyond the nostril; wings comparatively short, rounded rather than pointed ... TYPE (and only known species). - Ochthœca salvini Taczanowski. Doubtless only the rarity in collections of Tumbezia salvini has prevented its pronounced generic characters from being recognized before. It has no near relationship to Ochthœca (a Temperate Zone group) nor, indeed, to any described genus. In its narrow bill, inconspicuous rictal bristles, long tail and general coloration it resembles Sisopygis more than any other genus known to me, but its much longer tarsi, more pointed wings, slightly rounded, instead of slightly forked, tail it differs conspicuously from that genus. In short, Tumbezia is worthy of a place in the small group of markedly distinct genera restricted to the Equatorial Arid Fauna." (Chapman 1925).
