Abstract
Abstract A new species, Chenophila nanseni sp. n., collected from covert quills of the barnacle goose Branta leucopsis (Anseriformes: Anatidae) in Svalbard (Spitsbergen) is described and female polymorphism is recorded in this species. In syringophilids this phenomenon was known only for representatives of the genus Stibarokris. The new species differs from the similar Ch. platyrhynchos by following features: in females of Ch. nanseni the anterior margin of the propodonotal shield is flat (vs. concave in Ch. platyrhynchos) and the lengths of idiosomal setae si, f2 and ag3 in Ch. nanseni are distinctly shorter than in Ch. plathyrynchos.
