Tropfenflügel-Ameisenfänger

Bestimmung

The dot-winged antwren is 10 to 12.5 cm (3.9 to 4.9 in) long and weighs 7.5 to 11.5 g (0.26 to 0.41 oz). The species has a long graduated tail. The sexes have different plumage. Adults of the nominate subspecies M. q. quixensis are mostly black. They have a partly concealed white patch between their shoulders. Their greater wing coverts have large white tips and the other coverts smaller ones. Their wing's underside shows additional white areas. Their flight feathers are dark gray with a brown tinge. Their central tail feathers are black and the rest have progressively larger white tips from inner to outer. Adult females have a blackish gray head and upperparts, a black throat, and rufous-chestnut underparts that is darkest on the breast. Their pattern of white on the wings and tail are like the male's.<p>The other subspecies of the dot-winged antwren differ from the nominate and each other thus:<p>Subspecies M. q. boucardi and M. q. virgatus intergrade in Honduras; they may form a single subspecies.

Taxonomie

The dot-winged antwren is the only member of genus Microrhopias, which was erected by the English zoologist Philip Sclater in 1862. It has these 10 subspecies:<p>Several authors have suggested that some of the subspecies deserve recognition as species due to differences in plumage, voice, and habitat associations. The Clements taxonomy groups M. q. boucardi, M. q. virgatus, and M. q. consobrina as "Boucard's" dot-winged antwren. It also groups M. q. intercedens and M. q. albicauda as the "white-tailed" dot-winged antwren.

Verbreitung und Lebensraum

The subspecies of the dot-winged antwren are found thus:<p>The dot-winged antwren inhabits somewhat different landscapes across its extremely large range. In general they are tropical evergreen and secondary forest heavily vegetated with vine tangles; the species favors edges and gaps but mostly not the interior of continuous forest. In northern Central America its habitat includes low semi-deciduous forest and some rainforest. In southern Central America it adds shaded cacao and guava plantations. In Ecuador and western Amazonia the species often favors stands of bamboo and várzea forest. In Mato Grosso subspecies M. q. bicolor most often occurs in gaps within terra firme forest. Subspecies M. q. emiliae is mostly associated with stands of Guadua bamboo.
