Dix espèces de Copépodes Cyclopoïdes siphonostomes ont été recueillies à l’Ile Maurice. Parmi ces espèces, huit sont nouvelles pour la science; un genre nouveau (Monocheres), appartenant à la famille des Asterocheridae, a été créé pour une de ces espèces (M. mauritianus). Les autres espèces nouvelles sont Asterocheres halichondriae, A. genodon, A. proboscideus, Asteropontius corallophilus, Acontiophorus brevifurcatus, Bradypontius pichoni et Pteropontius pediculus. Deux espèces, Asterocheres mucronipes et Myzopontius australis, étaient déjà connues, la première de la Méditerranée occidentale, la deuxième de l’Australie.

Description of a new species of Metaniphargus, M. venezolanus, from a cave in northern Venezuela. This is the first representative of the hadziid group of genera of the family Gammaridae to be found in South America. It is closely related to certain Caribbean, insular taxa.

Notodelphyidae and Botryllophilidae (Copepoda) from the West Indies

Ano: 1983

URL: http://www.repository.naturalis.nl/record/504478

Notodelphyidae and Botryllophilidae are families of cyclopoid copepods, usually associated with Tunicata. Although SARS (1921) considered the families closely related, and placed them together in his suborder Notodelphyoidea, LANG (1946) showed that this group was polyphyletic. The two families are treated here together, simply because both are associated with the same host group. Through unforeseen circumstances (loss of part of the material while sent out on loan), the publication of this paper was considerably delayed. Certain details that had to be checked, could not be verified owing to the loss of the material involved. In my opinion, however, the available data are still of sufficient interest to warrant publication.

Amsterdam Expeditions to the West Indian Islands, Report 17. Les Cyathura stygobies (Isopoda, Anthuridea) et surtout celles des Grandes et des Petites Antilles

Ano: 1970

URL: http://www.repository.naturalis.nl/record/506151

Botosaneanu, Lazare; Stock, Jan H..

After a review of the morphology of the stygobiont species of Cyathura, five new species are described (one from Cuba, two from Haiti, one from Jamaica, and one from Aruba), and additional details are provided for some other species. Considerations are made on the peculiarities of the geographic distribution of the 11 stygobiont species known at present (forming a circum-Caribbean group and an Indo-Pacific one). A study of the relationships between the various species, and comparison with the non-stygobiont (marine or brackishwater) species of the genus, allows the definition of a subgenus Cyathura s. str. (for all non-stygobiont forms and two marine-interstitial ones) and of a new subgenus, Stygocyathura (containing most of the stygobiont species). In the...

Amsterdam Expeditions to the West Indian Islands, Report 47. Stygobiont amphipod crustaceans of the hadzioid group from Haiti

Ano: 1981

URL: http://www.repository.naturalis.nl/record/505431

The stygobiont gammarids of Haiti are more diversified than anywhere else in the world: not less than 13 species (all new) in 7 genera (5 new) and 4 subgenera (all new) are described of a somewhat loosely delimited group called the hadzioids/weckelioids. Practically all species have limited ranges within Haiti, whose stream systems apparently have acquired a great deal of isolation. The morphology of these amphipods makes even more indefinable the various supra-generic units proposed in the last 10 years for the “Gammaridae s.l.”

Associations of Hydrocorallia Stylasterina with gall-inhabiting Copepoda Siphonostomatoidea from the south-west Pacific. Part II. On six species belonging to four new genera of the copepod family Asterocheridae

Ano: 1985

URL: http://www.repository.naturalis.nl/record/504340

No specialized Copepoda associated with stylasterine corals were recorded thus far. Six different species in four genera (all new) are described. They have been found in cage-like galls on Conopora laevis (three species, in three different genera, from the Kermadec Islands and from New Zealand), Stylaster sanguineus (one species, from the New Hebrides), Stylaster papuensis (one species, from Papua), and Crypthelia cryptotrema (one species, from New Caledonia). The six copepod species appear to be phylogenetically related and belong to the family Asterocheridae (suborder Siphonostomatoidea). Based on the morphology of these new taxa, the value of the subfamily Cletopontoniinae of the Asterocheridae is called in question.

Consequences of the discovery of Stenasellus (Crustacea, Isopoda, Asellota)² in the underground waters of Oman (Arabian Peninsula)

Magniez, Guy J.; Stock, Jan H..

An overview of the present knowledge of the family Stenasellidae (Asellota; Aselloidea) is presented, focusing on the success of recent investigations of the underground waters of Oman (S.E. Arabian Peninsula). We take up the discovery of four new species of the genus Stenasellus: small species adapted to interstitial biotopes and larger ones typical of karstic aquifers. These species cohabit in ecotones between interstitial and karstic water systems. The putative presence of stenasellids in hypogean waters of Yemen and South Iran is suggested. The taxonomic status of the genus Stenasellus auct. needs to be reconsidered in the future. A scenario to explain the origin and the presence of these isopods in continental underground waters is advanced.

The Zoogeography of the crustacean suborder Ingolfiellidea, with descriptions of new West Indian taxa

Ano: 1971

URL: http://www.repository.naturalis.nl/record/504584

In a previous paper (STOCK, 1976b) I described, after a fortuitous find of a single specimen, an Ingolfiellid from a brackish well in Bonaire under the name of Ingolfiella (Gevgeliella) putealis. Financial support of the “Treub Maatschappij” (Utrecht) permitted me to revisit Bonaire in June 1976. At this occasion, a rich additional material of I. (G.) putealis could be collected in several brackish wells on the island; moreover, samples from a freshwater spring in Bonaire and from a marine interstitial habitat in Curaçao yielded Ingolfiellids as well, which proved to belong to undescribed species. This brings the total number of species known from the West Indies to three. Thanks are due to Mr. P. HOETJES and Mr. E. WESTINGA, for attempts to collect...

The Calvocheridae, a family of copepods inducing galls in sea-urchin spines

Ano: 1977

URL: http://www.repository.naturalis.nl/record/506152

Misshapen spines in sea-urchins of the family Echinothuridae were observed several times by the famous Danish echinoderm specialist, the late Dr. Th. Mortensen. The swellings were caused, he discovered, by a small crustacean inhabiting a cavity in the swelling. He entrusted his material to H. J. HANSEN, who published a detailed study on the phenomenon in 1902, whereas new samples discovered later on were studied by K. STEPHENSEN (1935). Apart from these two publications, no new observations concerning these galls in sea-urchin spines have been published. HANSEN gives an illustration of the transformed spine (1902, pl. XV fig. 1); this illustration, copied in the present paper (fig. 1a) gives the impression that the parasite inhabits a thickened part at the...

Stygofauna of the Canary Islands, 9. The amphipod genus Pseudoniphargus (Crustacea) in the Canary Islands

Ano: 1968

URL: http://www.repository.naturalis.nl/record/504140

Pseudoniphargus was known from inland stygohabitats in the Iberian peninsula, the Azores, Madeira, N.W. Africa, and Bermuda, but not from the Canary Islands. Systematic sampling in six of the seven larger islands of the latter archipelago has revealed the presence of the genus in Tenerife (4 species), La Palma (2 species), La Gomera (1 species), and El Hierro (1 species). No Pseudoniphargus has been found in Lanzarote and Fuerteventura; Gran Canaria has not been sampled systematically.

A new member of the crustacean suborder Ingolfiellidea from Bonaire, with a review of the entire suborder

Ano: 1963

URL: http://www.repository.naturalis.nl/record/506202

A single specimen of an ingolfiellid was found in a slightly brackish well (locally called a “pos”) on the Bacuna estate in the island of Bonaire (Netherlands Antilles). The specimen differs from all other 21 ingolfiellid taxa, and is described as a new species, Ingolfiella (Gevgeliella) putealis. The two classification systems in use for the Ingolfiellidea, that of KARAMAN (1959) and that of RUFFO (1970), are compared and both are found not entirely satisfactory in the light of recent discoveries. A new system is devised, in which the suborder is divided into 2 families, together with 3 genera and 5 subgenera. The genera and subgenera do not only represent morphological unities, but also combine species with similar habitat requirements. Within the...

The taxonomy and zoogeography of the hadziid amphipoda, with emphasis on the West Indian taxa

Ano: 1976

URL: http://www.repository.naturalis.nl/record/506101

The origin of the Antillean inland water fauna is discussed. It is assumed that the West Indian islands have been populated along three different lines: by dispersal, by divergence (fragmentation) and by stranding of marine elements during regression periods. – The phylogeny of the hadziid amphipods appears to correspond with the Regression Model. – The members of hadziid group are enumerated, the differences between the genera are tabulated and keyed. – The type-species of the genus Hadzia, H. fragilis, is re-examined. Hadzia taveresi is transferred to the new genus Metahadzia. – The genus Metaniphargus is re-surrected; its type-species M. curasavicus is re-described after topotypes and divided into two subspecies. Of M. nicholsoni, M. beattyi, and M....

Deux espèces nouvelles du genre Collocheres, C. breei (Méditerranée occidentale, hôte Ophioderma longicauda) et C. uncinatus (Golfe d’Aqaba, hôtes Heterometra savignyi et Oligometra serripinna) ont été décrites. Certains caractères de ces nouvelles espèces, et une étude critique des espèces déjà connues, ont conduits àla réunion des genres Collocheres et Leptomyzon. Une clé de détermination des formes appartenantes à Collocheres, dans le sens nouveau, a été fournie. Certains animaux décrits comme C. gracilicauda diffèrent nettement de la forme typique de gracilicauda; aussi, je propose C. gracilipes nom. nov. pour le matériel signalé par Canu et Sars.

Nannallecto fusii n. gen., n. sp. a copepod parasitic on the pteropod, Pneumodermopsis

Ano: 1966

URL: http://www.repository.naturalis.nl/record/505171

A new genus and species of copepod crustacean, Nannallecto fusii, is recorded parasitic on the pteropod, Pneumodermopsis (Pneumodermopsis) paucidens (Boas, 1886), from a surface tow off French Guiana. The parasite is obviously related to the only other adult copepod associate known from pteropods, the recently discovered Micrallecto uncinata Stock, 1971, and it appears to belong likewise to the family Splanchnotrophidae. The present new genus differs chiefly from Micrallecto in the presence of strong maxillipeds.
