Description
Summary: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). : Published as part of Parapar, Julio, Palomanes, Verónica, Helgason, Gudmundur V. & Moreira, Juan, 2020, Taxonomy and distribution of Pectinariidae (Annelida) from Iceland with a comparative analysis of uncinal morphology, pp. 1-32 in European Journal of Taxonomy 666 on page 22, DOI: 10.5852/ejt.2020.666, http://zenodo.org/record/3899270 : {"references": ["Malmgren A.
