On The Zoogeography Of Southern African Decapod Crustacea

Decapods are a culmination of nearly 600 million years of Crustacean evolution, during which time they have radiated into a variety of superfamilies, families, genera and species which occupy a variety of niches from fresh mountain streams to the abysses of the oceans. This book will fill a gap in the current literature on southern African decapods. Since Barnard published his Descriptive Catalogue of South African Decapod Crustacea in 1950, there have been numerous additions and name changes. This publication updates the taxonomy, and includes ecological and fisheries information. In addition, Kensley’s (1981) distributional checklist for the region has been updated and includes large numbers of new species and records for the region, bringing the total number of decapod to over 1000 species. Although not exhaustive, 262 species are featured, some of which are beautiful, some have commercial or artisinal value, both for consumption and the aquarium, and some have important ecological functions, while others are rare or interesting. For each species there is a photograph, synonymies, common names, a description, ecological information and name derivation (etymology). All the decapod families found in South Africa are described, some new, along with chapters on decapod research history in southern Africa, commercial and artisinal food value of decapods, biodiversity and future research direction. The book is arranged systematically, as taxonomy is based on phylogeny, starting with the earliest forms and progressing to the most derived and advanced forms, and will serve to stimulate interest and future research into southern Africa’s rich decapod biodiversity, especially at a time when biodiversity itself is threatened by global warming, coral bleaching and habitat loss. It will appeal to people interested in Decapoda, including academics, scholars, students, fishermen, aquarists, aquaculturists, recreational snorkel and SCUBA divers, as well as those interested in conservation, biodiversity, management and governance.

Thesis includes copies and discussion of Kensley's published papers: The constitution of the intertidal fauna of rocky shores of Mogamedes, Southern Angola (written with Mary-Louise Penrith); The constitution of the intertidal fauna of rocky shores of South West Africa. Part I, Lüderitzbucht, and Part II, Rocky Point (written with Mary-Louise Penrith); Some decapod crustacea from northern South West Africa, including a new species of Hippolyte; The genus Callianassa (crustacea, decapoda, thalassinidea) from the west coast of South Africa; Benthonic marine fauna obtained off the Orange River mouth by the diamond dredger Emerson-K (written with J.R. Grindley); Deep sea decapod crustacea from west of Cape Point, South Africa; The occurrence of Grapsus grapsus tenuicrustatus (Herbst) at the Tsitsikama Coastal National Park (Decapoda, brachyura, grapsidae); Decapod crustacea from the south-west Indian Ocean; A small collection of decapod crustacea from Moçambique; The family Sergestidae in the waters around southern Africa (crustacea, decapoda, natantia); The genus Gennadas in the waters around Southern Africa; Shrimps & prawns of southern Africa; Pseudione elongata africana, a new subspecies of bopyrid isopod from the west coast of the Cape Peninsula, South Africa; Bopyrid isopoda from southern Africa; A new species of Clausidium from South Africa (copepoda, cyclopoida, clausidiiae); Termitophilous isopods form southern Africa.

The papers in this volume have been grouped according to the main sub-themes of the congress and primarily deal with the biodiversity issues of invasive crustacea, ecology and behaviour and fisheries and aquaculture.

Among the deep-sea marine invertebrates, pycnogonids and crustaceans represent ecologically important and most diverse groups of species. Yet both are still poorly understood. Sampling and exploring operations off the west and east coast of the Americas has significantly increased in the last two decades. However such operations are very costly and limited in number and frequency. In countries like Brazil, Canada, Chile, Colombia, Costa Rica, Mexico, Peru, the United States of America, and El Salvador a large effort has been made to explore the deep-sea resources and the rich diversity of the communities, resulting in a better understanding of the natural ecosystems on both coasts of America. Pycnogonids and many groups of deep-sea crustaceans have been intensively studied, from the smallest animals, like the mostly unknown benthic copepods to the largest decapods. This book presents new and updated information on various groups of deep-sea pycnogonids and crustaceans occurring off the American continent. Offering a valuable reference resource for scientists interested in this fascinating fauna, it includes review papers and new data on the deep-sea communities occurring off the USA, Mexico, El Salvador, Costa Rica, Colombia, Chile, Peru, Brazil and Argentina, as well as in larger areas in both the East Pacific and the West Atlantic. As such it covers most of the current deep-water research in Latin America.

In the present new classification, the section Callianassida comprises two superfamilies, Axioidea and Callianassoidea, 19 families including one new family and two families with a new status, 8 subfamilies including one subfam. nov., 116 genera including 41 gen. nov. and 8 genera sensu nov., and 419 species including 12 spp. nov. and 2 nom. nov.
