Derbel H., Châari M. & Neifar L. 2011. — Redescription of Rhipidocotyle galeata (Rudolphi, 1819) (Digenea, Bucephalidae), the type species of Rhipidocotyle Diesing, 1907. Zoosystema 33 (2): 133–139.

Rhipidocotyle galeata (Rudolphi, 1819), the type species of the genus, is redescribed using material from Lichia amia (Linnaeus, 1758) (Actinopterygii, Perciformes) collected from the Gulf of Gabès in the Mediterranean Sea off Tunisia. Rhipidocotyle galeata is compared with other nominal species of the genus, including R. genovi, R. minima, R. triglae and R. viperae. This redescription provides additional information about the position and the distribution of the vitelline follicles, which form an arc that does not extend anteriorly past the level of the ovary, an uterus that extends almost to the posterior margin of the rhynchus and an ovary that is positioned adjacent to the anterior testis. A key to the eight Rhipidocotyle species from the Mediterranean Sea is presented.

Christoffersen M. L. 2011. — Catalogue of the Lumbricidae (Annelida, Clitellata, Lumbricoidea) from South America, with remarks on the systematics of the Lumbricina. Zoosystema 33 (2) : 141–173.

A catalogue of terrestrial Lumbricidae produced 28 nominal taxa (species and subspecies) reported to date from South America. Full synonyms and detailed South American occurrences are provided for each entity. This is the first detailed assessment of the distribution of South American Lumbricidae. Bimastos sophiae, known only from Argentina, and Eiseniella tetraedra cerni, known only from Chile, are presently the only taxa restricted to South America. The remaining species are widely distributed in temperate regions of the globe. Lumbricinae are of Holarctic origin and are mainly restricted to subtropical latitudes in South America, except for the mountain ranges of the Andes, extending northward into the tropical region up to Colombia and then the mountain ranges extending eastward along the Guayana shield along Venezuela and the Guyanas; in Brazil, lumbricids are restricted to the southern and southeastern states, primarily in the colder subtropical climate region and mountain ranges. The Lumbricina are megadrile earthworms characterized by a multilayered clitellum, eggs small relative to microdriles, gastrulation by emboly, intestinal specializations such as the typhlosole, a complex circulatory apparatus, two pairs of testicles and sperm sacs, and the male pores located at least two segments behind the posterior testes. The Lumbricoidea, which retain relatively small eggs, form the sister group of the Gondwanan Glossoscolecoidea plus Megascolecoidea, a clade characterized by having large ovaries with several egg-strings.

Bonato L., lorio É. & Minelli A. 2011. — The centipede genus Clinopodes C. L. Koch, 1847 (Chilopoda, Geophilomorpha, Geophilidae): reassessment of species diversity and distribution, with a new species from the Maritime Alps (France). Zoosystema 33 (2): 175–205.

Diagnosis, circumscription, species-level taxonomy and geographical occurrence of the genus Clinopodes C. L. Koch, 1847 (Chilopoda, Geophilomorpha, Geophilidae) are revised by integrating published information with new evidence on its morphological diversity. Clinopodes is clearly distinguishable from all other geophilid lineages by a combination of features mainly in the forcipular segment, the trunk sternites and the ultimate legs. It is widespread in south-eastern Europe, from the Alps to the Caucasus. A total of 10 species are recognized, mainly differing in minor features of the forcipular coxosternite and the arrangement of sternal and coxal pores: C. carinthiacus (Latzel, 1880) n. stat.; C. caucasicus (Selivanov, 1884) n. comb. formerly Geophilus caucasicus; C. escherichii (Verhoeff, 1896); C. flavidus C. L. Koch, 1847; C. intermedius Dărăbanţu & Matic, 1969; C. latisternus (Attems, 1947) n. comb. from Pleurogeophilus latisternus; C. rodnaensis (Verhoeff, 1938); C. skopljensis (Verhoeff, 1938); C. verhoeffi n. nom. (for Geophilus flavidus porosus Verhoeff, 1934); C. vesubiensis n. sp., Geophilus lindbergi (Loksa, 1971), n. comb. formerly Clinopodes lindbergi, is demonstrated to have been classified erroneously under Clinopodes. Clinopodes vesubiensis n. sp. is described from a limited area in the southern Maritime Alps, at the western border of the entire range of the genus, and disjunct from the morphologically closest species C. carinthiacus, suggesting that the history of differentiation and colonization of the genus within the Alps has been more complex than previously thought.

Yang C.-H., Chen I.-S. & Chan T.-Y. 2011. — A new slipper lobster of the genus Galearctus Holthuis, 2002 (Crustacea, Decapoda, Scyllaridae) from New Caledonia. Zoosystema 33 (2): 207–217.

Material previously identified as Galearctus kitanoviriosus (Harada, 1962) from New Caledonia has been found to consist of two distinct species. These species differ in the shape of the gastric tooth, third pereiopod propodus, antennal segment IV and thoracic sternum. The shallow water form is the true G. kitanoviriosus, while the deep-water form is new to science. Genetic comparison of the sequence of the barcoding gene, mitochondrial cytochrome c oxidase subunit (COI), also supports the separation.

Chiesa I. L. & Alonso G. M. 2011. — Redescription and generic assignment of Fuegiphoxus uncinatus (Chevreux, 1912) (Crustacea, Amphipoda, Phoxocephalidae). Zoosystema 33 (2): 219–233.

The genus Fuegiphoxus Barnard & Barnard, 1980 comprises four species widely distributed exclusively in the Southern Ocean. Fuegiphoxus uncinatus (Chevreux, 1912) had been assigned provisionally to this genus. In the present paper, Fuegiphoxus uncinatus is redescribed on the basis of the holotype and it is confirmed as belonging in the genus Fuegiphoxus. The diagnosis of Fuegiphoxus is emended and comparisons with the most related genera are provided. Furthermore, an identification key for the four known species of the genus, F. uncinatus, F. abjectus Barnard & Barnard, 1980, F. inutilus Barnard & Barnard, 1980 and F. fuegiensis (Schellenberg, 1931), is presented.
