Notodelphyidae and Botryllophilidae (Copepoda) from the West Indies
Provedor de dados: 16
Autores: Stock, Jan H.
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
Provedor de dados: 16
Autores: 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...

Autores: Stock, Jan H.
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
Provedor de dados: 16
Autores: Stock, Jan H.
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)
Provedor de dados: 16
Autores: 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.

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...

Autores: Stock, Jan H.
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...

A new member of the crustacean suborder Ingolfiellidea from Bonaire, with a review of the entire suborder
Provedor de dados: 16
Autores: Stock, Jan H.
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 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.

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.

Amsterdam Expeditions to the West Indian Islands, Report 28. Predation as a factor influencing the occurrence and distribution of small Crustacea in West Indian groundwaters
Provedor de dados: 16
Autores: Stock, Jan H.
Hadziid Amphipoda are known from inland groundwaters of 14 West Indian islands, Thermosbaenacea from those of 9 islands. Only 4 islands show joint occurrence of both groups. Even in islands of joint occurrence, hadziids occur significantly more often alone in a given locality, than in combination with Thermosbaenacea or Copepoda Cyclopidae. The latter two groups do not show any significant avoidance of each other. Some possible causes for the non-random occurrence of small groundwater Crustacea are discussed; it seems most likely that hadziids predate on other Crustacea, such as Thermosbaenacea or Cyclopidae. This predation may have, or have had, influence on the actual distribution patterns of the groups under consideration.

Quite a few endoparasitic copepods are known from Indo-Pacific stony corals, but not a single species has so far been recorded from the West Indies. Intensive search in the past few decades has even supported the prevailing opinion that West Indian stony corals are devoid of endoparasitic copepods, and that this absence could be related to the complicated zoogeographic past of the West Indian reef. However, during a 6-months stay (November 1973—April 1974) at the Caribbean Marine Biological Institute, in Curaçao (Netherlands’ Antilles), endoparasitic copepods have been found in not less than 14 species of stony corals. Some of these belong to a new family of curiously transformed animals, the CORALLOVEXIIDAE, of which the following forms were found during...

The genus Pseudoniphargus has long been considered monospecific.

A taxonomie revision revealed that at least nine named species and several unnamed forms (of which insufficient material is available) hide under the name Ps. africanus, each with a narrow ecological and geographical range.

Peltomyzon rostratum n. gen., n. sp., a siphonostome cyclopoid copepod associated with the West Indian coral Montastraea
Provedor de dados: 16
Autores: Stock, Jan H.
A new species representative of a new genus of Copepoda is described. It belongs to the subfamily Cletopontiinae of the family Asterocheridae (Cyclopoida siphonostoma). The new genus is chiefly characterized by the 2-segmented nature of the endopodites of legs 3 and 4, by the absence of an exopodite in the posterior antenna, and by the strongly developed tergum of the 2nd metasomite, giving the animal a shield-shaped appearance. Only the female sex of this copepod has been found; it is an associate of the hermatypic coral Montastraea cavernosa (L.) on the South coast of Curaçao (Netherlands’ Antilles), in depths from 4 to 40 meters.

A new genus and two new species of the crustacean order Thermosbaebacea from the West Indies
Provedor de dados: 16
Autores: Stock, Jan H.
Up to now, the crustacean order Thermosbaenacea contained two genera with only six valid species, five from the panmediterranean region, one from Texas. Two new members of this curious group of “living fossils” have been discovered in the West Indies. The one, from two deep wells not far from the sea coast in Saint Croix (U.S. Virgin Islands), belongs to an undescribed species of the amphiatlantic genus Monodella, and is called M. sanctaecrucis. The other was found in several localities in Curaçao (Netherlands’ Antilles), in coral débris of rubble walls on the shore; it belongs to a new genus, Halosbaena showing several remarkable adaptations, e.g. having a uniramous first pereiopod and reductions in the maxilliped. The presence of very numerous...

Autores: Stock, Jan H.
Dr. Ernst Frederik Jacobi, who was a member of the Editorial Board of this journal for exactly 20 years, reached the age of 65 on September 11, 1973 and retired. Dr. Jacobi was appointed Director of the Amsterdam Zoo (officially: of the Royal Zoological Society “Natura Artis Magistra”) on April 1, 1953, in succession to Dr. A. L. J. Sunier. The function of Director of the Zoo automatically means also the membership of the Editorial Board of “Bijdragen tot de Dierkunde”. This periodical was published by the Royal Zoological Society until vol. 28 of 1949 (the last volume edited by Dr. Jacobi’s predecessor), but owing to the difficult financial situation of the Society, its publication was interrupted from 1949 to 1959, when vol. 29 appeared.

Provedor de dados: 16
Autores: Stock, Jan H.
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).

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...

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.

Provedor de dados: 16
Autores: Stock, Jan H.
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 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.

Les Gammaridae (Crustacés, Amphipodes) des eaux douces et saumâtres de Corse
Provedor de dados: 16
Autores: Stock, Jan H.
Eleven species of Gammaridae, belonging to six genera, have been recorded from Corsica. Of these, only three are purely limnic, all others are found in mixohaline habitats. The three limnic species show a clear systematic relationship to italian taxa; the mixohaline species are of a circum-mediterranean type. Apart from two apparently endemic species of the genus Niphargus, there is no pronounced endemism in the corsican Gammaridae.

Pycnogonida collected in interstitia of coral sand and rubble in the Netherlands Antilles. Amsterdam Expeditions to the West Indian Islands, Report 58
Provedor de dados: 16
Autores: Stock, Jan H.
Seven species of Pycnogonida are recorded from the islands of Curaçao and Bonaire, living in coral debris (sand, rubble), often quite deep (40—80 cm) in the sediment. Two species (both new) occur in larger numbers and are considered truly interstitial. The others possibly are only accidental in this kind of habitat.

Sur trois especes de Copepodes synonymes ou confondues: Asterocheres echinicola (Norman), A. parvus Giesbrecht et A. kervillei Canu (Cyclopoida Siphonostoma)
Provedor de dados: 16
Autores: Stock, Jan H.
Asterocheres echinicola (Norman, 1868) is a common associate of marine sponges (Halichondria, Haliclona, Grantia) on the Dutch North Sea and French Channel coasts. It is proved that A. kervillei Canu, 1898, is a synonym of A. echinicola and that Sars (1915), Klie (1933), and Lang (1949) recorded this species under the erroneous name Ascomyzon parvum.

Whale-lice (Amphipoda: Cyamidae) in Dutch waters
Provedor de dados: 16
Autores: Stock, Jan H.
Three species of whale-lice are recorded from Dutch waters: Platycyamus thompsoni (Gosse, 1855), Cyamus catodontis Margolis, 1954, and Isocyamus delphinii (Guérin-Méneville, 1836). Cyamus catodontis is recorded moreover for the first time from several subantarctic localities. Isocyamus delphinii is recorded from a new host, Phocoena phocoena (Linnaeus, 1758). The records for C. catodontis and I. delphinii constitute considerable extensions of the known range.

Amsterdam Expeditions to the West Indian Islands, Report 6. Arubolana imula n. gen., n. sp., the first hypogean cirolanid isopod crustacean found in the Lesser Antilles
Provedor de dados: 16
Autores: Botosaneanu, Lazare; Stock, Jan H.
Arubolana imula, a new stygobiont isopod genus and species of the family Cirolanidae is described from Aruba (Netherlands Antilles). The new taxon has been discovered in an artificial tunnel, used for the production of industrial water, cut into calcareous rocks from marine origin which were rather recently uplifted above sea level (90,000-500,000 years B.P.). This is the first hypogean cirolanid that becomes known from the Lesser Antilles. The quite characteristic and simplified morphology of the posterior maxillae and maxillipeds, the subterminal position of the appendix masculina, and the prehensile nature of the first and second pereiopods, distinguish the new genus very clearly from all other hypogean genera in the family Cirolanidae. The feeble...

Amsterdam Expeditions to the West Indian Islands Report 4
Provedor de dados: 16
Autores: Stock, Jan H.
In the period 1973-1978 members of the Institute of Taxonomic Zoology (Zoölogisch Museum) have sampled the non-marine fauna of 27 West Indian islands. The present report records the stations in which stygobionts (= groundwater organisms) were collected . The main purpose of the program was to test the value of various biogeographic models for explaining the insular fauna. Since in general the fauna of inland waters yields good results in biogeographic analyses, the program was mainly directed to this fauna.

On twelve species of the genus Acanthomolgus (Copepoda Cyclopoida: Lichomolgidae) associated with West Indian octocorals
Provedor de dados: 16
Autores: Stock, Jan H.
Nine new species of Acanthomolgus are described, associated with octocorals from the Netherlands’ Antilles. In addition, notes on three species known already are provided. The species of the genus are subdivided into two groups, the mononyx-group which is exclusively West Indian, and the dionyx-gtoup which is predominantly, but not exclusively, Indo-West Pacific. A key to the West Indian species is presented. Host specificity is strongly pronounced in these associates.

A revision of the European species of the Echinogammarus pungens-group (Crustacea, Amphipoda)
Provedor de dados: 16
Autores: Stock, Jan H.
A revision of the species belonging to the group of, or confused with “Gammarus” (now Echinogammarus) pungens H. Milne Edwards, 1840 is given. Not less than 7 species have, at one or more occasions, been confused with E. pungens. All of these, and a number of related forms, are described and illustrated in detail, in several cases after consultation of the original or of the type material. In order to stabilize the nomenclature of this group, a neotype is selected to replace the lost types of Gammarus pungens. A key to the species is provided. The subgenera Homoeogammarus and Parhomoeogammarus, as well as the genus Ostiogammarus, are synonymized with Echinogammarus. The subgenus, or genus, Marinogammarus is synonymized with Chaetogammarus.

Autores: Stock, Jan H.
A new species of Pycnogonida, Anoplodactylus ophiurophilus, is described. It is associated with three species of the genus Ophiocoma in the Seychelles (Indian Ocean) and constitutes the first recorded case of a sea spider found on Ophiuroidea. In comparison with the 83 species actually recognized in Anoplodactylus, the new species shows hardly any morphological adaptations due to this remarkable association.

Microparasellidae (Isopoda, Asellota) from Bonaire
Provedor de dados: 16
Autores: Stock, Jan H.
During a study still in progress on the fauna of phreatic waters of various West Indian islands, a number of isopods of the family Microparasellidae were obtained. Although material from some 20 Caribbean islands was examined, only the island of Bonaire yielded microparasellid isopods so far. These animals are described in the present paper. Up to now, the only other West Indian records for the family are those of COINEAU &amp; BOTOSANEANU, 1973, from Cuba. The methods employed are the same as in my previous study (STOCK, 1976a) on the Antillean Thermosbaenacea. All chlorinities have been determined with the aid of an E.E.L. electric chlorinimeter.

Copepoda (Crustacea) associated with commercial and non-commercial Bivalvia in the East Scheldt, The Netherlands
Provedor de dados: 16
Autores: Stock, Jan H.
Six species of Copepoda Poecilostomatoida of the families Myicolidae, Sabelliphilidae, Lichomolgidae, and Mytilicolidae are recorded from six different species of intertidal bivalves in the East Scheldt (The Netherlands), a branch of the southern bight of the North Sea. One bivalve species may harbour more than one species of copepod, and one copepod species may use more than one species of bivalves as host. Mytilicola orientalis and Myicola ostreae are new to the North Sea, both being undoubtedly carried in accidentally with oriental oysters, successfully introduced for mariculture. In the light of the damage that was caused by Mytilicola intestinalis to Dutch mussel cultures in the past, the acclimatization of M. orientalis is a matter of concern, the...

Amsterdam Expeditions to the West Indian Islands, Report 14. The taxonomy and zoogeography of the family Bogidiellidae (Crustacea, Amphipoda), with emphasis on the West Indian taxa
Provedor de dados: 16
Autores: Stock, Jan H.
The diagnosis of a family of groundwater Amphipoda, the Bogidiellidae, is revised. Based on a cladistic analysis, the former genus Bogidiella is subdivided. In its present conception, the Bogidiellidae comprise eleven named genera, seven subgenera, and 50 named species, whereas several other taxa remain unnamed. These are distributed over all major continents (except Antarctica), and some oceanic islands. This distribution pattern is presumably due to at least two major vicariant processes: the breakup of Pangaea in the Mesozoic and the geological regression movements in the Tertiary. A number of West Indian taxa is described, including four new species.
