Taxonomy of the genera, Dictyuchus and Calyptralegnia is reviewed and a key has been composed for the better known species. Four species recorded from Iraq (D. monosporus, D. pseudoachly aides, D. carpophorua and C. ripariensis) have been described and illustrated. Monthly isolations from the Shatt Al-Arab estuary from Sept., 1976 to Aug., 1977 have rovealed that species of Dictyuchus occur throughout the year but are more abundant during spring and autumn, while C. ripariensia occurs only during the winter months.
