Systematic sampling has proved that members of the genus Echinogammarus are known from limited areas of Morocco. In this paper, we describe a new species of Echinogammarus (Crustacea, Amphipoda): Echinogammarus oujdae n. sp. from freshwater of the northeastern region with remarks on its affinities and ecology.

Amathillopsis charlottae n. sp. from the Antarctic Ocean is described herein, the first record of the Amathillopsidae from this region. The new taxon differs from all other known species of this family by the combination of: long carina on pleonite 3, urosomite 1 without carina, accessory flagellum of antenna 1 uniarticulate, mandibular palp article 2 only weakly shorter than 3 and telson entire. The genus Cleonardopsis, formerly classified as Eusiridae, is transfered into Amathillopsidae.

Members of the strictly stygobiont, continental subterranean amphipod family Metacrangonyctidae are reported for the first time outside the Old World. Two new species of Metacrangonyx are described from two widely separated localities in the Dominican Republic (Hispaniola), one facing the Caribbean and the other the Atlantic ocean. The discovery of metacrangonyctids in the western Atlantic suggests that they are an ancient subterranean lineage tied to the shores of the Tethys belt, and thus weakens previous biogeographic arguments raised to favour their separate and independent family status with respect to the Hadziidae. The discovery in the Mediterranean of marine populations of metacrangonyctids is reported as well, and both findings are used to test...

The Caprellidae (Crustacea: Amphipoda) of shallow waters of the Caribbean coast of Colombia, South America, are investigated. This is the first study dealing with the caprellidean fauna of this area. A total of 45 stations from Punta Brava to Punta Cañaveral, at Santa Marta region, Colombia, was selected, and samples of algae, coral rubble, sponges, hydroids, bryozoans and sediments were collected from the intertidal zone to 30 m depth. Ten species in seven genera were found (three of which are new to science): Aciconula sp., Caprella cf. penantis Leach, 1814, Caprella danilevskii Czerniavskii, 1868, Deutella caribensis n.sp., D. incerta (Mayer, 1903), D. mayeri Stebbing, 1895, Hemiaegina minuta Mayer, 1890, Paracaprella pusilla Mayer, 1890, Pseudaeginella...

Cladistic analysis of the family Stenothoidae (Amphipoda, Crustacea)

Krapp-Schickel, T.; Koenemann, S..

The amphipod family Stenothoidae contains more than 200 species in about 40 genera; these genera are at present often defined not by the presence, but by the absence of synapomorphies, thus defining grades rather than clades. Our phylogenetic analyses yielded 4 groups of stenothoids: a basic proboloidid clade; an advanced and always clearly separated Austral-Antarctic thaumatelsonid clade, with a possibly related Arctic mesometopid clade; and finally a poorly resolved group, the stenothoids sensu stricto, including the large and probably polyphyletic genera Stenothoe and Metopa, each with more than 50 species. It is proposed to study and analyse these groups separately in future, based on better redescriptions of the individual species. Our analyses...

Interspecific interactions between surface and subterranean species may be a key determinant for species distributions. Until now, the existence of competition (including predation) between these groups has not been tested. To assess the coexistence and potential role of interspecific interactions between surface Gammarus fossarum and subterranean Niphargus timavi, and to determine their micro distributions, we conducted a series of field and laboratory observations. We aimed to determine: (1) species substrate preference, (2) whether the presence of G. fossarum influences the habitat choice of N. timavi, and (3) possible predation effects on micro habitat choice of small juveniles. Throughout a small river in SW Slovenia, N. timavi was predominantly found...

Within the superfamily Gammaroidea oostegites vary from broad (primitive) to narrow (advanced). Broad oostegites are found in members of the Acanthogammaridae, Macrohectopidae and a few of the Gammaridae. Most species of the family Gammaridae have broad anterior oostegites and narrow posterior ones. Marine Gammarus species and Echinogammarus show a narrowing trend in the anterior oostegites as well.

A total of 1257 caprellids, mostly females, were collected, from Februaty to September 1991. The average sex-ratio was of 0,83, with a range from 1,58 and 0,20. Salinity ranged from 30 to 36 seawater and air temperature ranged from 26,00 to 17,66ºC and 25,23 to 18,60ºC respectively. Caprellid densities were higher during the cold months and males were the largest of the population. Males could be distributed in 12 length classes, while females in seven only.

Spalial and temporal density distributions of Amphipoda from the phytals of Caiobá are described. Air temperature oscillated from 16ºC (August and May) to 23ºC (March), surface water temperature from 17ºC (August) to 25ºC (March) and the salinity from 29.3 (May) to 32.8 (August). Two samples of 25cm² (for algae less than 5cm long), 100 cm² (for algae between 5-10cm long) and whole plants (for algae more than 10cm long) were removed with a spatula from the rocky surface at Caiobá Beach, in August/86, November/86, March/87 and May/87. After sorting, the algal substrata were weighted, their adsorption coefficient calculated and the sediment retained among the thallii weighted. The average distance between the branching was measured for all branched algae....

The new amphipod species Epimeria heldi is described. It differs from all known eperimiids in the following combination of characters: apically rounded coxae 1-3, the characteristic sculptured coxal plate 4, the narrow basis 7 and uropod 3 rami apically rounded. The body colour of the living animal is grey, with dark red mouthparts and appendages, and yellow eyes.

A new species of Pseudoniphargus has been discovered in Gran Canaria in a spring at an altitude of 710 m a.s.l.; it has an elongate peduncle of the male uropod 3. Moreover, P. fontinalis was found in the same island; this is the first record outside Tenerife from where it was described. The biogeographical implications of these records are studied.

Los caprélidos son comunes y abundantes en muchos hábitats litorales del ambiente marino. Sin embargo este grupo de anfípodos no ha sido muy bien estudiado en la costa chilena. El estudio de los caprélidos se ha visto dificultado por su gran variabilidad morfológica y el hecho de que la literatura así como los especímenes de los museos son difíciles de localizar. El objetivo de este estudio fue entregar las herramientas taxonómicas para la identificación de las especies de crustáceos caprélidos comunes en el centro-norte de la costa de Chile.

Leite,Fosca Pedini Pereira.

Day and night densities, reproductive biology and life cycle of Amphilocus neapolitanus (Della Valle, 1853), associated with Sargassum cymosum C. Agardh, 1820, were studied during 13 months. The density of juveniles, males and females was higher in night samples than in day samples. Sex ratio was strongly favorable toward the females. Ovigerous females were present in similar densities in both the periods while the non-ovigerous females were predominant at night. The egg number was not correlated with the size of the females. Breeding occurred throughout the year.
