URCEOLARIA SERPULARUM ( FABRE-DOMERGUE, 1888)

Fam. Serpulidae – on the branchial lamellae; Concarneau, France, the Bay of Biscay, north-eastern Atlantic Ocean ( Fabre-Domergue, 1888, as Leiotrocha serpularum ).

Nephtys sp. (Fam. Nephtyidae ) – Bay of Kiel, Germany, Baltic Sea ( Precht, 1935, as Cyclochaeta serpularum ).

Phyllodoce laminosa Savigny in Lamarck, 1818 (Fam. Phyllodocidae ) – Bay of Kiel, Germany, Baltic Sea ( Precht, 1935, as C. serpularum ).

Serpula sp. (Fam. Serpulidae ) – branchiae; Germany ( Kahl, 1935, as Cyclochaeta (Leiotrocba) serpularum ).

Remark: Urceolaria serpularum was originally described in the monotypic genus Leiotrocha Fabre-Domergue, 1888 . Haider (1964) transferred Leiotrocha serpularum into the genus Urceolaria , which was accepted by Xu & Song (2003), but not by Lynn (2008), who insisted on validity of the monotypic family Leiotrochidae Johnston, 1938 . Recent morphological and genetic analyses by Zhan et al. (2013) support that Leiotricha should be placed in Urceolaria .
