motacilloides
Genus Motacilla Linnaeus, 1758, wagtail; Gr. -οιδης -oidēs  resembling (e.g. from black and white plumage, and long flirted tail).
● "15.  HERPSILOCHMUS MOTACILLOIDES, Jelski, in litt.  Pileo nigro albo maculato, fronte rufescente, dorso griseo; subtus albus, flavido tinctus; vitta superciliari alba, postocularis nigra.  Tectrices alarum nigræ, albo maculatæ; remiges fusco-nigricantes, griseo limbati; rectrices medianæ nigricantes, laterales albæ.  Rostrum et pedes nigricanti-plumbei; irides fusco-brunneæ." (Taczanowski 1874) (Herpsilochmus).
● "73.  PERICROCOTUS CINEREUS, Lafr. Rev. Zool. 1845, p. 94.  (P. motacilloides, mihi.)  A female of this, or of a nearly allied species, appears to have been described under the name P. cinereus.  ...  In fact the plumage of the male has great affinity to that of the wild Motacillæ, and also forms a happy transition from the grey Campephagæ to the crocus-tinted Pericrocoti." (Swinhoe 1860) (syn. Pericrocotus divaricatus). 
● "Genus.  RHIPIDURA.   ...   2. MOTACILLOIDES.  Rhip. nigra; macula  superciliari, pectore medio, abdomine, crissoque albis; remigibus nigro-fuscis.  ...  It bears a great resemblance to the description of Dr. Latham's Motacilla atricapilla, or the Black-topped Flycatcher of his "General History", but differs in the colour of the bill, back and throat.  The latter species most probably belongs to the present group." (Vigors & Horsfield 1827) (syn. Rhipidura leucophrys).
