The genus Collettea Lang, 1973 (previously Strongylura Sars, 1882) is revis
ed. Two new species, C. humbolti, sp. nov. from Antarctica and C. cylindrat
oides, sp. nov. from the southeast Australian slope and Antarctica, are des
cribed. C. minima (Hansen, 1913) is redescribed and additions are included
to the description of C. arnaudi (Shiino, 1978). A key to the genus is prov
ided. The systematic position of Collettea with respect to the subfamilies
of Anarthruridae is discussed.
