Gymnotus carapo and G. anguillaris (syn.: G. coropinae), two often confused species of gymnotid fishes (Pisces, Cypriniformes)
Provedor de dados: 16
Autores: Nijssen, H.; Isbrücker, I.J.H.
The species Gymnolus anguillaris Hoedeman, 1962 has been collected all over Surinam. The authors suggest the possibility that G. anguillaris is widely distributed in South America, because it is hitherto confused with the closely related G. carapo Linnaeus, 1758. Besides it is proved that G. coropinae Hoedeman, 1962 has to be regarded as a synonym of G. anguillaris.

The amphipod, Gammarus tigrinus Sexton, 1939, introduced in the Netherlands (Crustacea)
Provedor de dados: 16
Autores: Nijssen, H.; Stock, J.H.
An alien amphipod, Gammarus tigrinus Sexton, has been observed in the Netherlands, mainly in oligohaline waters. It has had an “explosive” development in the Yssellake (the former Zuydersea) and occurs also in a great number of inland waterways in the province of North-Holland (fig. 1). It co-exists with, and often outnumbers, the local gammarids, G. pulex, G. zaddachi and G. duebeni. It is expected that the extension of its range will continue next years; fig. 2 illustrates the range of this introduced species in autumn 1965. Since Irish specimens of G. tigrinus were released in 1960 in the Yssellake, it is not clear whether the Dutch populations originate from the Irish stock, or whether that they were accidentally, e.g. in ballast tanks, carried to the...

Rhadinoloricaria gen. nov. and Planiloricaria, two genera of South American Mailed Catfishes (Pisces, Siluriformes, Loricariidae)
Provedor de dados: 16
Autores: Isbrücker, I.J.H.; Nijssen, H.
This paper deals with two genera of loricariid fishes: Rhadinoloricaria gen. nov., and Planiloricaria Isbrücker, 1971. Rhadinoloricaria is established for the species macromystax, described by Günther (1869: 426) in the binomen Loricaria macromystax. Planiloricaria, elevated to generic rank in the present paper, was described by Isbrücker as a subgenus of the genus Pseudohemiodon Bleeker, 1862, for the new species cryptodon (Isbrücker, 1971: 278). Diagnoses of these two monotypic genera are given, together with redescriptions and figures of their type-species. The relationships with other genera within the subfamily Loricariinae are discussed. A provisional subdivision into six genus-groups is given, and a new subfamily name, Acestridiinae, is proposed for...

Autores: Nijssen, H.; Tuijl, L. van; Isbrücker, I.J.H.
This catalogue resulted from our attempts (since 1963) to accommodate and modernize the labelling of type-material of Recent fishes in the collections of the Zoölogisch Museum Amsterdam (ZMA), now named Institute of Taxonomie Zoology, University of Amsterdam. We traced 6625 type-specimens of 714 nominal species or subspecies, 228 of which are primary type-specimens (holotype, lectotype, or neotype); moreover, the collection contains one or more syntypes of 222 nominal (sub-) species. A few syntypes are presently indicated as future lectotype in the collection, awaiting publication by various specialists. Such specimens are not distinguished in this catalogue. It is possible that lectotype designations for some species have been validly published, which...

On three specimens of Lagenorhynchus albirostris Gray, 1846 (Mammalia, Cetacea)
Provedor de dados: 16
Autores: Bree, P.J.H. van; Nijssen, H.
Recently the Zoological Museum in Amsterdam came into possession of three specimens of the White-beaked Dolphin, Lagenorhynchus albirostris. As data on this species are rather scarce, it may be useful to publish a few notes on these animals. The first dolphin, a female, was caught in the North Sea at 7.3 miles N.N.W. from IJmuiden (about 52° 34’ N, 4° 30’ E) at the end of November 1958 by a commercial fish-trawler. The animal was obtained by the Netherlands Whale Research Group T.N.O. (Prof. dr. E. J. Slijper and Drs. W. L. van Utrecht), Amsterdam, for anatomical studies. Afterwards the skull and the complete skeleton were presented to the Zoological Museum. The dolphin was pregnant, its fetus weighed 1.5 kg. This specimen bears the registration number ZMA...

Provedor de dados: 16
Autores: Nijssen, H.
Gammarus fossarum Koch, 1835 est une espèce commune dans la partie sud du Limbourg (Pays-Bas), où elle est présente dans l’eau douce, non polluee, d’un pH de 6,2 à 7,0. Les études en campagne, effectuées en 1962 démontrent la présence de l’espèce à six localités en dehors du Limbourg, c’est-à-dire près d’Arnhem et de Nimègue, où elle vit dans les mêmes conditions qu’au Limbourg. D’ailleurs, il y a un échantillon de Gammarus fossarum au Musée zoologique d’Amsterdam, ramassé en 1949 dans un ruisseau dans la commune de Gendringen (la Gueldre), mais des recherches plus récentes ne découvrirent pas sa présence en cet endroit, fait probablement attribuable à la pollution actuelle de ses eaux.

Hypopygus lepturus Hoedeman, 1062, was hitherto known from the holotype and one paratype only, both imported aquarium specimens. In this paper the type locality of the species is restricted. Additional distributional data from Surinam are given, together with records on the occurrence of H. lepturus in Guyana, Venezuela, Colombia, Brazil, and on the very likely occurrence in Peru. Comparative notes on Steatogenys elegans (Steindachner, 1880) sensu Boulenger, 1898, are added because of the similar appearance of both species. The synonymy of Tateichthys duidae La Monte, 1929, with Steatogenys elegans is established.

Revision of the Surinam Catfishes of the genus Corydoras Lacépède, 1803 (Pisces, Siluriformes, Callichthyidae)
Provedor de dados: 16
Autores: Nijssen, H.
During recent expeditions to Surinam, large ichthyological collections have been made from nearly all river systems by several ichthyologists, one of which was the author. Because of new information provided by the especially rich collections of Corydoras, a revision of the Surinam species and subspecies of this genus was thought necessary. This revision is based on 5211 specimens belonging to seventeen species and subspecies of which seven are new to science, viz., C. bondi coppenamensis, C. guianensis, C. heteromorphus, C. octocirrus, C. oelemariensis, C. schwartzi surinamensis and C. saramaccensis. A key to the Surinam species is provided and the taxonomic value of several characters is discussed. The distribution of the different groups within the...

Provedor de dados: 16
Autores: Nijssen, H.; Tuijl, L. van; Isbrücker, J.H.
This is a revision of the catalogue issued in 1982 (Nijssen et al.) of type specimens of Recent fishes in the collections of the Zoölogisch Museum Amsterdam (ZMA), also named Institute of Taxonomic Zoology of the University of Amsterdam. These include 203 holotypes, 3 neotypes, 56 lectotypes, 1839 syntypes, 5965 paratypes, and 1010 paralectotypes of 884 nominal species or subspecies. Of syntype series, only the specimens still present in the ZMA collection are recorded. In many cases, specimens of such series have been sent on exchange among others to Vienna (1915), Leiden (1917 and following), Manilla, New York (1927) and London. Whether or not all of these specimens are really syntypes is not clear, due to incomplete curatorial administration during the...

New data on Metaloricaria paucidens from French Guiana and Surinam (Pisces, Siluriformes, Loricariidae)
Provedor de dados: 16
Autores: Isbrücker, I.J.H.; Nijssen, H.
A large number of previously unrecorded specimens of mailed catfishes of the genus Metaloricaria Isbrücker, 1975 (Loricariinae, tribe Harttiini, subtribe Metaloricariina) is compared with the known specimens from French Guiana and Surinam. This results in the recognition of two subspecies, viz., M. paucidens paucidens Isbrücker, 1975, from the rivers Oyapock and Maroni (French Guiana, Surinam), and M. p. nijsseni (Boeseman, 1976) from the rivers Suriname, Saramacca, Nickerie and Corantijn (Surinam). These subspecies were originally described as two different species, even within two different genera: Metaloricaria paucidens Isbrücker, 1975, and Harttia nijsseni Boeseman, 1976. Morphometric and meristic data, together with illustrations are given of the two...

Otoliths of the wolf-fishes (genus Anarrhichas Linnaeus, 1758) from the Northern Atlantic (Pisces, Perciformes)
Provedor de dados: 16
Autores: Nijssen, H.
While working at the Rijksinstituut voor Visserijonderzoek (R.V.I.O.) at IJmuiden, I received through the courtesy of Mr. C. van Delft some specimens of the three northern Atlantic species of wolf-fishes. At IJmuiden they are brought in by commercial trawlers. The only data in the literature known to me concerning the otoliths of Anarrhichas are those furnished by FROST, 1929. This author published only very sketchy illustrations of two of the northern Atlantic species. I thought it useful, therefore, to describe, illustrate and compare in this paper the otoliths of all three Anarrhichas species. The three species of wolf-fishes in the northern Atlantic are: Anarrhichas lupus, A. minor and A. latifrons. The otoliths (sagittae) in this genus are of very...

The South American Mailed Catfishes of the genus Pseudoloricaria Bleeker, 1862 (Pisces, Siluriformes, Loricariidae)
Provedor de dados: 16
Autores: Isbrücker, I.J.H.; Nijssen, H.
Two species of South American Mailed Catfishes of the genus Pseudoloricaria Bleeker, 1862 are redescribed and figured from type-specimens and additional material: Pseudoloricaria laeviuscula (Valenciennes, 1840), and Pseudoloricaria punctata (Regan, 1904). Since the provenance of the holotype of P. laeviuscula is unknown, the type-locality of this species is restricted to the mouth of the Rio Tapajós at Santarém. The lectotype is selected from the three syntypes of P. punctata, and its type-locality is restricted to the Rio Amazonas at Manaus. P. laeviuscula is distributed only in the Rio Amazonas basin in Brazil, whereas P. punctata occurs in several river systems, viz. the Rio Amazonas basin in Brazil, Peru, and Ecuador, in the Rio Parnaiba, Est.

Provedor de dados: 16
Autores: Nijssen, H.; Isbrücker, I.J.H.
A redescription and figures of Corydoras nattereri Steindachner, 1877, are given together with a description and figures of a new species, Corydoras prionotos, sympatric with Corydoras nattereri, with comparable dimensions and a similar colour pattern. A total of 1066 specimens were examined, including primary type-material of Corydoras juquiaae Von Ihering, 1907, and of Corydoras nattereri triseriatus Von Ihering, 1911, which are both placed in synonymy of C. nattereri, the holotype of which is lost. A neotype for Corydoras nattereri is designated. Corydoras prionotos differs from C. nattereri mainly in having the medial border of the pectoral-fin spine strongly serrate.
