A new eunicid species, Leodice duplexasp. n., from intertidal and subtidal habitats in the eastern coast of South Korea is described. The new species is assigned to the C-2 group, and is similar to Leodice antennata, the type species of the genus, in having the following combination of characteristics: moniliform antennae and palps, bidentate compound falcigers, articulated peristomial and noto...

The inner tube layer of Pomatoceros americanus has a complex oriented ultrastructure, which cannot be explained by the standard granular secretion model, predicting a largely unoriented structure of the tube. In the lamello-fibrillar structure of the inner tube layer, the crystallization axis of crystals has a uniform orientation, which is not continuous through successive growth increments. Th...

The aims of this research were to: (1) investigate the species richness of wawo worms, and to (2) analyze macronutrient content of the worms. Wawo worms were sampled using a fishing net on March 18(th)-19(th), 2014, from Ambonese waters, Maluku. As many as 26 wawo species belonging to 5 families were identified. Palola sp. was identified as the most abundant species of wawo, followed by Lysidic...

r nae is the virilis–repleta radiation, as evaluated by the umber of species and species groups (Throckmorton, 962, 1975). The virilis and repleta species groups have een extensively used as model systems in the studies f mechanisms of speciation, mapping genes, and chroosomal rearrangements (Patterson and Stone, 1952; owell, 1997). Drosophila virilis is a prominent refernce species for compari...

Two new species of the cirratulid genus Tharyx are reported from shallow waters in the Kattegat inshore Sweden. In addition, the lectotype of Tharyx killariensis (Southern, 1914) is redescribed resulting in a revised concept of the noto- and neuropodial acicular spines of posterior parapodia for that species. These spines were originally reported as bidentate crotchets with sharply pointed teet...

Among polychaetes, polynoids have the highest number of symbiotic species found living with a wide variety of marine invertebrates, including other polychaetes. Lepidasthenia Malmgren, 1867 and Lepidametria Webster, 1879 were regarded as synonyms but belong to different subfamilies, although both have species associated with thelepodid or terebellid polychaetes. In this contribution Lepidasthen...
