DEFINITIONS

CERCOMACROIDES
(Thamnophilidae; Ϯ Dusky Antbird C. tyrannina) Genus Cercomacra P. Sclater, 1858, antbird; Gr. -οιδης -oidēs  resembling; "Because the group of species referred to as the 'tyrannina' clade does not have an available name, we erect a new genus that recognizes the monophyly and distinct nature of this group.   CERCOMACROIDES J. G. TELLO & M. A. RAPOSO, GEN. NOV.  Type species: Cercomacroides tyrannina (Sclater, 1855), comb. nov., Dusky Antbird (= Cercomacra tyrannina [Sclater], 1855)  ...  Cercomacroides can be distinguished from Cercomacra by the lack of conspicuous white tips on the rectrices of both sexes; by the predominantly warm buff-brown or orange buff plumage in females; by the whistling loudsongs and non-synchronized vocal duets; and by building deep pouch-shaped nests with oblique entrances.  Etymology: The Latin suffix -oides, taken from ancient Greek 'eidos' means 'having the likeness of'. Our choice of the name Cercomacroides is an allusion to the great shape and plumage similarity among the species of Cercomacroides and those of the genus Cercomacra, probably as a result of convergence" (Tello et al. 2014); "Cercomacroides Tello and Raposo in Tello, Raposo, Bates, Bravo, Cadena, and Maldonado-Coelho, 2014, Zool. Journal Linnean Soc., 170 (3), p. 555.  Type, by original designation, Cercomacra tyrannina P. Sclater, 1855." (JAJ 2020).
