DEFINITIONS

ZOONAVENA
(Apodidae; Ϯ Madagascar Spine-tail Swift Z. grandidieri) Genus Zoonava Mathews, 1914, swiftlet; L. suffix -ena  relating to (cf.  Gr. ζωον zōon  creature; L. advena  stranger); "The last form I will discriminate is perhaps more interesting than any of the others, as it suggests the keynote to the solution of the evolution of the Spine-tailed Swifts.  This is Chætura grandidieri Schlegel, which lives at Madagascar.  Superficially in every detail, save its tail, it is a "Collocalia" of the Zoonava group.  It absolutely agrees in detail as to coloration and, moreover, has the nostrils placed as in the "Collocalia" group, not as in the "Chætura" typical series.  Further, the second primary appears to be longest, which is a character of the former, but not of the latter.  The superficial resemblance is so great that it possesses a MS. name showing its determination as a "Collocalia."  A natural classification will almost certainly prove that is its nearest relationship and that the evolution of the Spine-tail is more recent than the acquisition of plumage coloration.  To initiate this quest, I propose to give it the new generic name ZOONAVENA with type Zoonavena grandidieri (Schlegel).  The tail-feathers are stiff, but the needle-points are quite minute." (Mathews 1918); "Zoonavena Mathews, Bds. Austr., 7, 1918, p. 265.  Type, by original designation and monotypy, Chaetura grandidieri Schlegel, i.e. Verreaux." (Peters, 1940, IV, p. 241).
