It is endemic to southeastern Brazil. == Taxonomy and systematics == The star-throated antwren was described and illustrated by the German naturalist Johann Baptist von Spix in 1825 and given the binomial name Thamnophilus gularis. It was subsequently placed with the "stipple-throated group" in the genus Myrmotherula, a group which later was itself transferred to genus Epinecrophylla. When a morphological and genetic analysis published in 2012 found that the star-throated antwren was not closely related to other species in Myrmotherula it was moved to genus Rhopias which had originally been erected by the German ornithologists Jean Cabanis and Ferdinand Heine in 1860. The type species is the star-throated antwren. The name of the genus comes from the Ancient Greek word rhōps meaning "bush". The star-throated antwren is the only member of genus Rhopias and it has no subspecies. Its closest relatives appear to be the banded antbird (Dichrozona cincta) and the two species of antwrens in genus Isleria. == Description == The star-throated antwren is 8.5 to 9.5 cm (3.3 to 3.7 in) long and weighs 10 to 12 g (0.35 to…
