B. Schierwater et A. Ender, Sarsia marii n. sp (Hydrozoa, Anthomedusae) and the use of 16S rDNA sequences for unpuzzling systematic relationships in Hydrozoa, SCI MAR, 64, 2000, pp. 117-122
A new hydrozoan species, Sarsia marii, is described by using morphological
and molecular characters. Both morphological and 16S rDNA data place the ne
w species together with other Sarsia species near the base of a clade that
developed, "walking" tentacles in the medusa stage, The molecular data also
suggest that the family Cladonematidae (Cladonema, Eleutheria, Staurocladi
a) is monophyletic. The taxonomic embedding of Sarsia marii n. sp. demonstr
ates the usefulness of 16S rDNA sequences for reconstructing phylogenetic r
elationships in Hydrozoa.
