| Haploginglymus hitherto was a monospecific genus, widely distributed, in subterranean waters (caves, wells) on the Iberian Peninsula. A new species of this genus, very clearly differentiated from the type-species H. bragai Mateus & Mateus, 1958, has been discovered in the interstitial of a spring brooklet in the province of Santander in Spain. This new species, of which only the female is known, is described as H. lobatus sp. nov. |

| A new species of Amphipoda, Psammogammarus caesicolus, is described from interstitial, anchihaline waters in Blauwbaai cave, Curaçao, Netherlands Antilles. By the morphology of the third uropod, the new species links the somewhat aberrant Ps. longiramus from the Red Sea with the type-species of the genus, Ps. coecus, from the Mediterranean. The classification of the Eriopisa complex, to which Psammogammarus belongs, is reviewed, resulting in a stricter delimitation of, presumably monophyletic, genera, and the creation of three new genera: Madapisella (type-species Eriopisa madagascarensis Ledoyer, 1968), Nippopisella (type-species Eriopisella nagatai Gurjanova, 1965), and Tunisopisa (type-species Eriopisa seurati Gauthier, 1936). The distribution of the... |

| Seventy-six species of Pycnogonida, and some unidentifiable forms, belonging to 25 genera in all 8 families, of which 13 species are new to science, are recorded from the Indo-West Pacific region. New species are described in the genera Ascorhynchus, Ammothella, Achelia, Pantopipetta, Nymphon, Callipallene, Phoxichilidium, Anoplodactyhis, and Pycnogonum. A phylogenetic hierarchy of the families of extant Pycnogonida is presented. |

Caribbean Region 71, Amsterdam 1992: 69-78. Hemicyclops geminatus n. sp. is described from the upper infralittoral zone of Curaçao (Antilles). It is a regular associate of three species of hermit crabs: Calcinus tibicen, Paguristes grayi, and Dardanus venosus. The new taxon appears to be a twin species of Hemicyclops columnaris HUMES, 1984, an associate of a stony coral off the Pacific coast of Panamá. |

| Ascension Island (08° S 14°25’ W) occupies a very peculiar place in our current research project on the biological properties of ground waters of the the Mid-Atlantic islands: -- The island lies closer to the equator than any of the other Mid-Atlantic islands. -- The island lies almost on the Mid-Atlantic Ridge, and far remote from any other insular or continental region. -- The island’s subaerial part consists of very young volcanic outcrops (dated radiometrically at 1-2 My). Through these properties, the comparison of Ascension with the intensively studied Canary Islands (see the series of publications of our team under the collective title “Stygofauna of the Canary Islands”, parts 1 to 19) is of great importance for a better understanding of dispersal... |

A new species of Propallene, P. ardua, is described from shallow waters and plankton tows near Kunduchi, Tanzania. Remarks on other species of the genus are provided, as well as a key to the species actually included in Propallene, |

| The present material has been collected at three occasions: during a stay on Curaçao and Bonaire (Netherlands Antilles) in 1958/59, and again in 1973/74, and during a visit in 1963 to La Parguera, Puerto Rico. The copepods recorded here as associates of Actiniaria and Corallimorpharia (Asclerocorallia) all belong to the Cyclopoida. Two sections of these are represented: the Poecilostomata and the Siphonostomata. Members of other copepod groups were not found in the Antillean region on the hosts in question. |

| In my recent revision of the Sarothrogammarus-group (Bijdr. Dierk., 41: 94—129, 1971), I consistently used the spelling Sarathrogammarus. Professor S. Ruffo, of Verona, kindly pointed out to me that the original spelling of the name is Sarothrogammarus (see Martynov, 1935, Trav. Inst. zool. Acad. Sei. URSS. 2: 484—506). Though the etymology of the word is not very clear (perhaps from σαρω = to brush, to clean), it is evident that there are no good grounds for the spelling Sarathrogammarus, as used by me. |

| Sixteen species of Pycnogonida are recorded from littoral or very shallow waters (0-3 m) of the coast of Oman. Four species are new to science: A. lagenaria, Ammothella omanensis, Achelia boschi, and Pycnogonum moolenbeeki. Since up to now no littoral Pycnogonida have been recorded from the Arabian peninsula, all other species are new to this region, with the exception of one which was recorded from deeper waters off Oman before. For some of them the range is considerably extended. |

| Stock, Jan H., 1995. Two new Copepods parasitic on Caribbean Polychaetes. Studies Nat. Hist. Caribbean Region 72, Amsterdam, 1995: 1-11. Two new species of Copepoda, each belonging to a new genus, are described from shallow waters in the Caribbean. One, Zygomolgides coronicolus n. gen., n. sp., is a member of the family Lichomolgidae, parasitic on the branchial crown of the serpulid polychaete Hydroides cf. brachyacanthus from St. Thomas (U.S. Virgin Islands). The other, Lobosomatium enigmaticum n. gen., n. sp., is a minute, curiously transformed copepod, of which all appendages (as far as present) are strongly reduced, found ectoparasitic on the body of a syllid polychaete, Brania glandulosa, from Curaçao (Netherlands Antilles). Due to the strong... |

| Area-species graphs for stygobiont Crustacea Malacostraca of seven islands in the southern Caribbean have been compared. It appears that the “constants” C and z of these graphs are influenced by the geological time elapsed since the island’s emergence. In older islands the values for C and z are higher than in younger islands. The values for z of younger and older islands are much higher (0.79-0.97) than usually obtained in literature for terrestrial animals (0.20-0.40). This may be explained by the very limited dispersal faculties of K-strategists, such as stygobiont Malacostraca. |

| The type-species of the genus Doridicola Leydig, 1853, D. agilis Leydig, 18 has been re-examined. The armature of the exopod of the fourth leg of D. agilis is II,I,5, thus identical to that of the genus Metaxymolgus Humes & Stock, 1972. Metaxymolgus is synonymized with Doridicola. Those species formerly attributed to Doridicola but having an armature of III,I,5 on the endopod of the fourth leg, are placed in a new genus, Critomolgus. |

| Twenty-seven species of Pycnogonida are recorded from the mediolittoral and infralittoral zones in the West Indies and of the north coast of South America, including two new species. Eurycyde acanthopus n. sp. was found on the shelf off the coast of Venezuela. Anoplodactylus monotrema n. sp. is widely distributed in the area; it has apparently been confused in the past with A. robustus (Dohrn, 1881). The morphology of the latter, and of the closely related A. virescens (Hodge, 1864), is discussed. Material from Amsterdam and St. Paul islands (Indian Ocean) attributed to A. virescens, is considered to belong to a separate species, A. dentimanus. – The range of several species is extended. Two species of Endeis, viz. E. meridionalis (Bohm, 1879) and E.... |

| The Sultanate of Oman is an arid country, forming the south-eastern margin of the Arabian peninsula, with coast lines on the Gulf of Oman in the north-east and the Arabian Sea in the south-east. In the interior, it is bordered on the Emirates in the north-west, Saudi-Arabia in the west, and Yemen in the south-east. Although today large parts of the Sultanate are formed by hot desert, this has not always been the case in its geological history. The occurrence of huge karst caves shows that precipitation must have been much higher in the past. On the other hand, ancient glacial deposits show that it lay closer to the South Pole some 600 million years (My) and again 300 My ago. |

| The new genus Collocherides, which is created for the reception of C. astroboae n. sp., is closely related to Collocheres. Whereas the species of Collocheres all are, as far as we know, ectoparasites of echinoderms, Collocherides was found endoparasitic in basket stars (Astroboa nuda, A. albatrossi) at Eilat (Israel), in the Dahlak Archipelago (Ethiopia), and in Indonesia. |
