DEFINITIONS

THRENETES
(Trochilidae; Ϯ Pale-tailed Barbthroat T. leucurus) Gr. θρηνητης thrēnētēs  mourner  (i.e. sombre) < θρηνος thrēnos  lament  < θρεομαι threomai  to shriek; "THRENETES LEUCURUS. White-tailed Barbed-throat.   ...   THRENETES CERVINICAUDA, Gould. Fawn-tailed Barbed-throat.   ...   THRENETES ANTONIÆ. Sooty Barbed-throat.  ...   ALTHOUGH this species has been long known to ornithologists, it was only in the year 1846 that it received a scientific appellation, M. Bourcier then assigning to it the name of Antoniæ in honour of Madame Antonia Perroud, the wife of a learned entomologist.  Since then it has been transferred to the genus Polytmus by Mr. G. R. Gray, and to Lampornis by the Prince of Canino. That it does not belong to either of those genera, or to any other at present established, is certain, and I have therefore been necessitated to propose a new generic term for it and its near ally T. leucurus. The circumstance of its having remained so long undescribed by Lesson and others, who have professed to give complete monographs of this group of birds, is doubtless due to its being unadorned by any brilliant or metallic colouring; its sombre plumage, however, does not, in my opinion, detract from its interest as a species; for in the economy of nature, this dull-coloured bird plays a part of equal consequence with those of its most gaily attired allies" (Gould 1852); "Threnetes Gould, Monogr. Trochil, pt. 4, 1852, pls. [14 and 15] [= 1, pl. 13 and 15 of volume]. Type, by subsequent designation, Trochilus leucurus Linné. (G. R. Gray, Cat. Gen. Subgen. Bds., 1855, p. 20)." (Peters 1945, V, 5). 
Synon. Dnophera, Heteroglaucis.
● (syn. Cisticola Ϯ Red-faced Cisticola C. erythrops) "The remaining three subgenera all have the tail with a subterminal black bar, the outermost primary not more than two-thirds of the length of the second. Of these C. erythrops (Hartlaub) has the back uniform, not striped, and I propose to place it in a new subgenus, THRENETES." (A. Roberts 1922) (see Threnolais).
