Revision of Chloeia Savigny in Lamarck, 1818 (Annelida, Amphinomidae)
"Abstract: Chloeia Savigny in Lamarck, 1818 is the largest genus in the Amphinomidae by including more species than other genera. Members of Chloeia species thrive in mixed substrates or sediments, mostly in tropical waters, and rarely reach deep water, or cold-temperate environments. A recent revision dealt with the species from tropical American seas and resulted in the redescription of five species, and the description of two other new ones. The objective for this additional contribution was to revise type and non-type specimens deposited in 12 of the largest world collections, and by applying a slightly modified approach from the precedent revision. Species were grouped herein after the ...
Revision of Pherusa Oken, 1807 (Polychaeta : Flabelligeridae)
Pherusa Oken, 1807 was the first genus of flabelligerids to be described and was regarded as having over 40 species. Following revision of all available material two morphological patterns are recognized: Pherusa is restricted to those species with eight branchial filaments of similar width, and anchylosed falcate neurohooks, shorter than body width. Species with the same number of branchial filaments but with neurochaetae mostly straight, distally foliose and often as long as body width are transferred to a new genus: Lamispina n. gen. Pherusa contains 14 species, including six newly described: P. plumosa (Müller, 1776), type-species, restricted, from Greenland, P. affinis (Leidy, 1855) fr...
Revision of Sternaspis Otto, 1821 (Polychaeta, Sternaspidae)
The peanut-shaped sternaspid polychaetes have been known since 1760 when Plancus named them as Mentula cucurbitacea marina. Sternaspids are common and abundant in soft bottoms. Some authors suggested that only one species should be recognized, whereas others regard a few species very widely distributed and variable depths. Delineating species was problematic; the ventro-caudal shield was disregarded or barely used for identifying species. In this contribution the ventral shield is evaluated and its diagnostic potential is confirmed. The revision of Sternaspis is based upon type or topotype materials. Sternaspid body, introvert hooks and shield show three distinct patterns: two genera have 7 ...
Revision of Fauveliopsidae Hartman, 1971 (Annelida, Sedentaria)
"Abstract: Abyssal polychaetes are usually difficult to be identified because they are small, their body patterns differ from their shallow water relatives, their delicate bodies are often damaged during sampling and sieving, and their taxonomy is in need of revision. Members of the family Fauveliopsidae Hartman, 1971 are widespread in deep ocean basins and they follow the above statements. In this contribution, we present a revision of all available type and non-type material for the family. Our objective is to provide keys to identify genera and species, as well as standardized diagnoses, and illustrations for most species, excluding those described since 2011, or where type material was n...

Pleistoannelida, Errantia II
This book is the fourth in a series of 4 volumes in the Handbook of Zoology series about morphology, anatomy, reproduction, development, ecology, phylogeny and systematics of Annelida. It covers the most typical polychaetes, Phyllodocida, together with certain smaller taxa placed incertae sedis. This volume completes the polychaetous Annelida. Phyllodocida are often vagile, possess well-developed parapodia. Due to their broad and flat cirri these parapodia look like leaves in some taxa and leading to the name of the entire group. Many of its members are macrophagous and often predators. Accordingly most species possess elaborate sense structures such as sensory palps, antennae, eyes and nuch...
