Ano: 1982

URL: http://www.repository.naturalis.nl/record/504740

Rineloricaria castroi n. sp. from Rio Trombetas, Est. Pará, Brazil, is described and illustrated. It is compared with R. phoxocephala (Eigenmann & Eigenmann, 1889) from Rio Amazonas at Coari, Est. Amazonas, Brazil, which species is here illustrated for the first time.

Two new species of the callichthyid catfish genus Corydoras from Brazil (Pisces, Siluriformes, Callichthyidae)

Ano: 1984

URL: http://www.repository.naturalis.nl/record/505023

This paper contains descriptions and figures of two new species of the neotropical callichthyid catfish genus Corydoras Lacépède, 1803, from Brazil, Corydoras pulcher from Rio Purus, north of Lábrea, Est. Amazonas, and Corydoras steindachneri from Paranaguá, Est. Paraná. The relationships of the new species with other species of Corydoras are discussed.

Gymnotus carapo and G. anguillaris (syn.: G. coropinae), two often confused species of gymnotid fishes (Pisces, Cypriniformes)

Ano: 1973

URL: http://www.repository.naturalis.nl/record/504870

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.

A redescription of the South American Catfish Loricariichthys maculatus (Bloch, 1794), with designation of the lectotype and restriction of its type locality (Pisces, Siluriformes, Loricariidae)

Ano: 1968

URL: http://www.repository.naturalis.nl/record/504834

The type species of the genus Loricariichthys Bleeker, 1862, Loricariichthys maculatus (Bloch, 1794), is redescribed from two syntypes, one of which is designated the lectotype. The same specimen is also designated the neotype for Plecostomus cataphracta Gronovius (ed. Gray), 1854 (non Loricaria cataphracta Linnaeus, 1758, sensu stricto). The type locality of both nominal species is restricted after a comparison to specimens recently collected from a locality in Surinam.

The South American Plated Catfish genus Aspidoras R. von Ihering, 1907, with descriptions of nine new species from Brazil (Pisces, Siluriformes, Callichthyidae)

Ano: 1971

URL: http://www.repository.naturalis.nl/record/503968

The South American callichthyid catfish genus Aspidoras R. von Ihering, 1907, is redefined on the basis of thirteen nominal species. Morphological differences with the related genus Corydoras Lacépède, 1803, are discussed. Two species originally described in Corydoras, viz., Corydoras raimundi and Corydoras pauciradiatus are herein transferred to Aspidoras. Aspidoras now consists of the following previously described nominal species: (1) Aspidoras rochai R. von Ihering, 1907 (type-species of the genus), known from Brazil, Est. Ceará, Fortaleza, (2) Aspidoras raimundi (Steindachner, 1907) from Brazil, Est. Maranhão, Rio Parnaíba system, (3) Aspidoras lakoi P. de Miranda Ribeiro, 1949, from Brazil, Est. Minas Gerais, Rio Paranaíba system, and (4) Aspidoras...

Ano: 1976

URL: http://www.repository.naturalis.nl/record/504152

Pseudohemiodon thorectes, a new species of Mailed Catfish of the subfamily Loricariinae, is described and figured after the holotype (the only known specimen), originating from Buena Vista, west of Rio Palacios, a tributary of Rio Mamoré, Bolivia. The relationships of the new species with the others of the genus Pseudohemiodon are discussed, and a preliminary key to the nominal species and subspecies is given.

Corydoras ornatus, a new species of callichthyid catfish from the Rio Tapajós Drainage, Brazil (Pisces, Siluriformes, Callichthyidae)

Ano: 1975

URL: http://www.repository.naturalis.nl/record/505024

A new species of the neotropical callichthyid catfish genus Corydoras Lacépède, 1803, C. ornatus, is described and figured. It is compared with Corydoras pulcher Isbrücker & Nijssen, 1973, a closely related species.

Two new species and a new genus of neotropical mailed catfishes of the subfamily Loricariinae Swainson, 1838 (Pisces, Siluriformes, Loricariidae)

Ano: 1976

URL: http://www.repository.naturalis.nl/record/505452

A new monotypic genus and two new species of South American mailed catfishes of the subfamily Loricariinae are described and figured. A discussion of and comparative notes on related taxa are added. Ricola genus novum is established for the species originally described by Regan (1904) as Loricaria (Loricaria) macrops. A lectotype for Ricola macrops is selected from the two syntypes, originating from Río de la Plata in Argentina/Uruguay. Ricola macrops is compared with species of the genus Loricaria Linnaeus, 1758. Loricaria prolixa species nova is described from Rio Piracicaba, Est. São Paulo, Brazil. It is compared with Loricaria macrodon Kner, 1854, and with Loricaria lata C. H. Eigenmann & R. S. Eigenmann, 1889. Pseudohemiodon apithanos species nova...

Rhadinoloricaria gen. nov. and Planiloricaria, two genera of South American Mailed Catfishes (Pisces, Siluriformes, Loricariidae)

Ano: 1978

URL: http://www.repository.naturalis.nl/record/504901

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...

A review of the genus Corydoras Lacépède, 1803 (Pisces, Siluriformes, Callichthyidae)

Ano: 1974

URL: http://www.repository.naturalis.nl/record/504983

A review of 99 species and subspecies of the genus Corydoras is given. The primary type-material is recorded together with additional type-specimens deposited in 22 different museum collections. Two neotypes and 22 lectotypes are designated. The species are arranged in five groups: 31 species in the punctatus-group, 11 in the barbatus-group, 25 in the aeneus-group, 8 in the elegans-group, and 19 in the acutusgroup. Measurements and counts of almost all primary typespecimens are tabulated. Ill-known illustrations of type-material are included.

A catalogue of the type-specimens of Recent fishes in the Institute of Taxonomic Zoology (Zoölogisch Museum), University of Amsterdam, The Netherlands

Ano: 1980

URL: http://www.repository.naturalis.nl/record/504333

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...

Review of the South American characiform fish genus Chilodus, with description of a new species, C. gracilis (Pisces, Characiformes, Chilodontidae)

Ano: 1982

URL: http://www.repository.naturalis.nl/record/506026

Examination of 291 specimens of Chilodus, a genus of South American fresh water fishes, yielded the presence of three species, viz.: C. punctatus, C. zunevei, and C. gracilis. Of the first species the lectotype is designated. The type material of C. zunevei is lost; new material enabled a redescription of this species. C. gracilis is described as a new species, although it is known as an aquarium fish since decades. The three species are illustrated; a key to them and a map showing their distribution are included.

The identity of the South American catfish Loricaria cataphracta Linnaeus, 1758, with redescriptions of the original type specimens of four other nominal Loricaria species (Pisces, Siluriformes, Loricariidae)

Ano: 1988

URL: http://www.repository.naturalis.nl/record/505107

This article contains figures and descriptions of Loricaria cataphracta Linnaeus, 1758, sensu stricto (neotype), Loricaria cirrhosa Bloch & Schneider, 1801 [identical with L. cataphracta] (lectotype and paralectotype), Loricaria flagellaris (Gronovius, 1854) (holotype), Loricaria carinata de Castelnau, 1855 (holotype), and Loricaria lata Eigenmann & Eigenmann, 1889, sensu stricto (lectotype and paralectotypes, in part). Another part of the paralectotype series of Loricaria lata represents another species, described but not named below, which eventually may prove not to belong to the genus Loricaria. The ultimate status of L. flagellaris and of L. carinata remains uncertain, there being too few additional data. In addition to L. cirrhosa, L....

On Hypopygus lepturus, a little known dwarf gymnotid fish from South America (Pisces, Cypriniformes, Gymnotoidei)

Ano: 1972

URL: http://www.repository.naturalis.nl/record/505243

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.

The South American catfish genus Brochis Cope, 1872 (Pisces, Siluriformes, Callichthyidae)

Palavras-chave: 42.81.

Ano: 1967

URL: http://www.repository.naturalis.nl/record/319319

Examination of the type specimens of Callichthys splendens Castelnau, 1855, Brochis coeruleus Cope, 1872 (type species of Brochis Cope, 1872), Brochis dipterus Cope, 1872, Corydoras semiscutatus Cope, 1872, Chaenothorax bicarinatus Cope, 1878 (type species of Chaenothorax Cope, 1878), and Chaenothorax eigenmanni Ellis, 1913, has demonstrated that they represent only one species: Brochis splendens. Callichthys taiosh Castelnau, 1855, also has to be considered a synonym of Brochis splendens. Chaenothorax multiradiatus Orcés-Villagomez, 1960, is a second species belonging to the genus Brochis.
