DEFINITIONS

CALAMONASTIDES
(Acrocephalidae; Ϯ Papyrus Yellow Warbler C. gracilirostris) Genus Calamocætor (= Calamoecetor W. Sclater, 1936) reed warbler (cf. genus Calamonastes Sharpe, 1883, wren warbler); Gr. -ιδης -idēs  resembling; "CALAMONASTIDES, gen. nov.  Description:— General characters and feet similar to the genus Calamocætor W. L. Sclater; but general colour olive-brown and yellow, and bill rather broader.  Type of Genus:— Chloropeta gracilirostris O. Grant, Bull. B. O. C. xix. 1906, p. 133.   ...   Remarks:— A comparison of the type of Chloropeta gracilirostris with members of the genus Chloropeta show that the feet are very large and the toes and claws long; and available field-notes show that it is a swamp dweller and not a forest dweller as are Chloropeta natalensis and races and Chloropeta similis. The large feet, toes and claws agree well with those of the genus Calamocætor, which is also a swamp dweller; but as the general colour is not in agreement with the known species of Calamocætor and the bill is rather broader we are of opinion that it is best placed in a genus of its own, which would follow the genus Calamocætor" (Mackworth-Praed & Grant 1940); "Calamonastides Grant and Mackworth-Praed, 1940, Bull. Brit. Ornith. Club, 60, p. 91.  Type, by original designation, Chloropeta gracilirostris Ogilvie-Grant." (Traylor in Peters, 1986, XI, p. 82).
