Pettibone, 1961 is a monotypic genus in the subfamily Polynoinae
Kinberg, 1856. It is characterized by having lateral antennae with
ventral ceratophores, cephalic peaks and neuropodia with pre-chaetal
lobes being longer than post-chaetal lobes. Phyllohartmania taylori
Pettibone, 1961 was described using only one specimen collected at Bird
Point, Seahorse Key, Florida. During a study of Polynoids from the
Grand Caribbean to corroborate features and records, the holotype and
additional material of P. taylori
housed at the National Museum of Natural History, Smithsonian
Institution were examined and an unknown genus of Eulagiscinae
Pettibone, 1997 confused with Phyllohartmania was found; the present study erects this as a new genus. Kristianides
gen. nov. is distinguished by having prostomium without cephalic peaks,
lateral antennae inserted terminally on indistinct ceratophores and
notopodia and neuropodia with projecting acicular lobes well developed.
sp. nov. differs from the other species of Eulagiscinae by having
ventral lamellae; 15 pairs of elytra with fringe of papillae, surface
with sclerotized microtubercles and macrotubercles; being conical the
microtubercles and cylindrical the macrotubercles. In addition, two
records of P. taylori from the northern Gulf of Mexico are published herein, as is a taxonomic key to differentiate Kristianides gen. nov. from its congeners in Eulagiscinae. This finding also increases the number of species with ventral lamellae, a convergent feature.
Key words: Eulagiscinae,
Polynoinae, Convergent features, Worms, Mississippi Sound, Elytra.
