Genus Lagis Malmgren, 1866

Type species and type locality

Lagis koreni Malmgren, 1866 . Finnmark ( Norway), lectotype in Naturhistoriska Riksmuseet, Stockholm, designated by Nilsen et al. (1977) (see Holthe 1986).

Remarks

The diagnosis of the genus by Hutchings & Peart (2002) states that neurochaetal uncini have large teeth arranged in two or more rows. Examination of BIOICE specimens of L. koreni shows again that there are changes in teeth shape with increasing size of an individual, reflected in a progressive reduction in the number of teeth rows with the age of the animal. This still fits the diagnosis of the genus (“two or more rows”) but a better definition of uncini shape is needed. In contrast to the other species studied here, the uncini are, in all body sizes studied, of the pectinate type (see below).
