Tassonomia

Johannes's tody-tyrant has a complicated taxonomic history. It was originally described in 1907 as Euscarthmus iohannis . [ 5 ] During different parts of the twentieth century it was treated as a subspecies of the stripe-necked tody-tyrant (now H. striaticollis ) and as a full species in genera Euscarthmornis and Idioptilon . Those two genera were eventually merged into Hemitriccus . [ 6 ] Johannes's tody-tyrant is monotypic . [ 3 ]

Areale e habitat

Johannes's tody-tyrant has a disjunct distribution in one large area and at least one much smaller one. The large area extends from most of eastern Peru and east into northern Bolivia and into western Brazil as far as the upper reaches of the Solimões , Juruá , and Purus rivers. A separate population is found in southern Colombia's Putumayo and Amazonas departments and possibly slightly into northeastern Ecuador. Another population is found in eastern Ecuador's Pastaza Province ; it appears to be isolated but might be contiguous with the far northwestern part of the Peruvian range. [ 7 ] [ 8 ] [ 9 ] [ 10 ] [ 11 ] Johannes's tody-tyrant primarily inhabits humid subtropical forest along watercourses and oxbow lakes , where it favors vine tangles and dense shrubby areas. In Colombia it is found in terra firme forest. In elevation it reaches 800 m (2,600 ft) in Peru, 400 m (1,300 ft) in Colombia, and about 200 m (700 ft) in Ecuador. [ 7 ] [ 9 ] [ 10 ] [ 11 ]
