Boudemos Watson 2016

Genus Boudemos Watson et al., 2016 Type species. Vigtorniella flokati Dahlgren et al., 2004. Diagnosis (from Watson et al., 2016 emend.) Very small to moderately large-bodied; length of mature individuals ~ 2 mm for 20 segments to 40 mm for ~ 90 segments, respectively. Eyes present or absent. Pair of stylet jaws present or absent. Notochaetae slender or robust with slight differences in margin serration pattern. Compound falcigerous neurochaetae with bifid joints. Prechaetal neuropodial lobe present in larger species, absent in smaller species. Neurochaetae with swollen inner joint and shallow groove on blades in larger-bodied species; absent in individuals of smaller-bodied species. Remarks. The diagnosis was emended to include the very small-bodied new species with paedomorphic chaetal characters (see Diagnostic Remarks). Bold text indicates characters present in all species of Boudemos. The genus Boudemos was erected for Vigtorniella flokati Dahlgren et al., 2004 inhabiting whale falls in the Pacific, and V. ardabilia Wiklund et al., 2009 from a whale fall in Sweden and fish farms in Norway (Watson et al., 2016). These two larger-bodied species are morphologically almost identical, but molecular evidence support their differentiation. The name Vigtorniella was retained for the type species, Vigtorniella zaikai (Kiseleva, 1992).
