Patricia Salazar-Silva (2020) Phyllohartmania
Pettibone, 1961 is a monotypic genus belonging to 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 record, the holotype and
additional material of P. taylori
housed at the National Museum of Natural History, Smithsonian
Institution were examined and unknown genus of Eulagiscinae Pettibone,
1997 confused with Phyllohartmania was found, here is erected 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 pair 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 for the northern Gulf of Mexico herein are published, is provided a taxonomic key to differentiate Kristianides gen. nov. from its congeners in Eulagiscinae and is increased the species with ventral lamellae, a convergent feature.
Key words: Eulagiscinae, Polynoinae, Convergent features, Worms, Mississippi Sound, Elytra.
