The genus Haplosyllis Langerhans, 1887 (Polychaeta, Syllidae, Syllinae) has an unresolved carmenbritoae Lattig, San Martín & Martin, 2007 and H. granulosa (Lattig, San Martín & taxonomy; it is characterized by the articulated cirri, palps fused only at bases and the simple Martin, 2007). bidentate chaetae. The genus is relatively small, includes 19 species, 5 incertae sedis and 4 The assignation of species to Haplosyllis has been traditionally based on the presence nomina dubia (present study).
