  • More ochraceous across breast
  • Thinner black streaks on sides
  • australis deeper ochraceous buff
  • pseudoaustralis like australis but with very pale wingbars

Similar species

Guianan Streaked Antwren has a less distinct malar stripe, a white interscapular patch, less distinct streaking on breast and 12 (rather than 10) rectrices.


Bolivia, Colombia, Ecuador, and Peru.
Still fairly common in its large range.


Four subspecies recognized:

  • M. l. soderstromi on the eastern slope of Andes of southern Colombia and northern Ecuador (Napo)
  • M. l. pseudoaustralis on the eastern slope of northern Ecuador (Zamora-Chinchipe) and northern Peru (south to Pasco)
  • M. l. longicauda in central Peru (Junín)
  • M. l. australis from southeast Peru (Cusco, Madre de Dios and Puno) to northwest Bolivia

A recently found population in Loreto (Peru) has not yet been assigned to a subspecies.


Moist lowland forest and montanes. Mostly in foothills at 400 to 1300 m, locally higher.



Feeds on small insects and spiders.
Forages usually in pairs or singly, mostly in shrubby thickets and crowns of understorey saplings. A very active species moving in zigzag through the forest, only pausing for very short moments. Also in mixed-species flocks.


No information.


Presumably a resident species.
