THE SOUTH AMERICAN NEMATOGNATHI of the MUSEUMS at LEIDEN and AMSTERDAM by J. W. B. VAN DER STIQCHEL the Collections of the South
THE SOUTH AMERICAN NEMATOGNATHI OF THE MUSEUMS AT LEIDEN AND AMSTERDAM by J. W. B. VAN DER STIQCHEL (Museum voor het OnderwSs, 's-Gravenhage) The collections of the South American Nematognathi in the Rijksmuseum van Natuurlijke Historie at Leiden, referred to in this publication as "Mu• seum Leiden", and of those in the Zoologisch Museum at Amsterdam, referred to as "Museum Amsterdam", consist of valuable material, which for a very important part has not been studied yet. I feel very much obliged to Prof. Dr. H. Boschma who allowed me to start with the study of the Leiden collections and whom I offer here my sincere thanks. At the same time I want to express my gratitude towards Prof. Dr. L. F. de Beaufort, who has been so kind to place the collection of the Zoological Museum at Amsterdam at my disposal. Furthermore I am greatly indebted to Dr. F. P. Koumans at Leiden for his assistance and advice to solve the various problems which I met during my study. The material dealt with here comes from a large number of collections of different collectors, from various areas of South America, it consists of 125 species, belonging to 14 families of the order Nematognathi. Contrary to the original expectations no adequate number of specimens from Surinam could be obtained to get a sufficient opinion about the occurrence of the various species, and, if possible, also about their distribution in this tropical American part of the Netherlands. On the whole the collections from Surinam were limited to the generally known species only. -

Endangered Species
FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.

ORCID: http://orcid.org/0000-0003-3746-6894. E-mail: [email protected] Abstract. Two new species of heptapterid catfish genus Cetopsorhamdia are described from close localities in western Brazil, at Chapada dos Parecis, an area with extremely high level of endemism. One species is from the upper Rio Madeira system, Rondônia State, and the other from the upper Rio Tapajós system, Mato Grosso State. The two species are diagnosed, among several other features, by their markedly distinctive color patterns, with the former having well-defined quadrangular marks in trunk flanks while the latter bearing irregular, vertical bars along the trunk. The monophyly of Cetopsorhamdia is discussed, with two putative synapomorphies being proposed to support the genus. Potentially informative morphological characters to resolve the internal relationships of the genus are presented and discussed. Despite the striking external differences between the two species herein described, they are found to likely form a clade. -

Neotropical Ichthyology, 3(3):401-410, 2005 Copyright © 2005 Sociedade Brasileira de Ictiologia Comparative description and discussion of spermiogenesis and spermatozoal ultrastructure in some species of Heptapteridae and Pseudopimelodidae (Teleostei: Siluriformes) Irani Quagio-Grassiotto, Maria Angélica Spadella, Márcio de Carvalho, and Claudio Oliveira The data obtained in the present study on spermiogenesis and spermatozoal ultrastructure of Pseudopimelodidae and Heptapteridae show that they share some characteristics, but greatly differ from each other. The main differences are the occurrence of type I spermiogenesis in Pseudopimelodidae and type III in Heptapteridae, the presence of nuclear fossa in Pseudopimelodidae and its absence in Heptapteridae, the presence of long midpiece in Pseudopimelodidae and short midpiece in Heptapteridae, the presence of cytoplasmic canal in Pseudopimelodidae and its absence in Heptapteridae, the presence of many large vesicles in the midpiece of Pseudopimelodidae and the presence of very long vesicles placed in the peripheral distal region in Heptapteridae, and mitochondria distributed all over the midpiece in Pseudopimelodidae, and very close to the nucleus in Heptapteridae. Heptapteridae and Pimelodidae share several characteristics, such as type III spermiogenesis, a similar chromatin condensation pattern, and the absence of nuclear fossa and flagellar lateral fins. The spermatozoa of Pseudopimelodidae is more similar to those of Siluridae. However, the absence of additional data on spermiogenesis
