of pileum short; anteorbital and postocular regions (A. rufigula) or suborbital, postocular, and lower portion of loral regions (A. bicolor and allies) naked; latero-frontal feathers short and erect (denser, more plush-like in A. rufigula).
Coloration. — Plain brown or olive, with throat tawny or rufescent, or with throat and median under parts white;[1] sexes alike or nearly so.
Range. — Honduras to Amazon Valley and Cayenne. (Eleven or more species recognized.[2])
KEY TO THE SPECIES OF ANOPLOPS.
a. Underparts brown (no white), becoming tawny or rufous on throat and auricular region. (British Guiana to lower Amazon Valley.)
Anoplops rufigula (extralimital).[3]
aa. Underparts broadly white medially, including throat; auricular region black or dusky.
- b. Above bright tawny-chestnut, more rufescent on forehead.
- c. Sides and flanks chestnut or rufous-chestnut. (Colombia.)
Anoplops ruficeps (extralimital).[4]
- cc. Sides and flanks olive-brown, becoming slate-grayish next to white of breast, etc. (Colombia and upper Amazon Valley.)
Anoplops leucaspis (extralimital).[5]
- bb. Above vandyke brown, not more rufescent on forehead.
- c. Forehead and postauricular regions slate color. (Eastern Panamá.)
Anoplops bicolor (p. 132).
- cc. Forehead and postauricular region brown, like pileum, etc. (Western Panamá, to eastern Honduras.)
Anoplops olivascens (p. 132).
- ↑ A. lunulata (Sclater and Salvin), a species which I have not seen, has black and ochraceous lunulations on the back, and whitish spots on inner webs of rectrices.
- ↑ Of these I have not seen the following: A. lunulata (Sclater and Salvin), A. salvini (Berlepsch), A. griseiventris (Pelzeln), A. cristata (Pelzeln), A. berlepschi Snethlage, A. hoffmannsi Hellmayr, A. pallidus Cherrie, and A. melanosticta (Sclater and Salvin). Anoplops lunulata differs from A. bicolor and its allies in more slender bill, much narrower and more broadly operculate nostrils, and very much denser as well as longer feathering of the loral region. The style of coloration is somewhat different, there being no white on the under parts, the chin and throat being rufous-tawny and the under parts of the body brown. The naked skin on sides of head, together with the legs and feet, are yellow, instead of blue and dusky horn color, respectively, as in A. bicolor, etc.
