A reconsideration of the diagnostic characters of Atya Leach and Atyoida Randall supports their generic separation. Accordingly, Atyoida is reinstated as a full genus of which the distinguishing features are slender third peraeopods with a relatively short merus, a tapering endopod in the male first pleopod and protandry. It includes three species, A. bisulcata Randall from the Hawaiian Islands, A. pilipes (Newport) widespread in the Indo-Pacific area, and A. striolata (McCulloch & McNeill) found only in Australia. A. striolata is fully redescribed. Morphological variation throughout its range is slight; no subspecies are distinguishable. It is suggested that larvae hatch in estuaries and that protandry is an adaptive life-cycle strategy.

This chapter emphasises that audio-visual (AV) resources are very fragile and need to be stored in ideal conditions to preserve them for posterity. It describes different types of AV materials and the conditions under which they should be kept. It is based on a study that was conducted in the Eastern and Southern Africa Regional Branch of the International Council on Archives (ESARBICA) region. Data were gathered using quantitative and qualitative methods. The results revealed lack of equipment to monitor environmental conditions, absence of policies to govern the acquisition, appraisal, access, preservation, retention, digitisation and disposal of AV materials, and failure to apply the records life cycle (or any model) to AV records. The results point to a need for national archives to develop guidelines that apply to AV materials particularly in Africa. Particular attention should be given to training AV archivists in the region using an integrated curriculum.
