Aquatic macroinvertebrates of an intermittent stream in the arid Hajar Mountains, Oman

Aquatic macroinvertebrates were collected from six habitats in two permanently flowing sites in Wadi Qahfi, northern Oman. A total of 38 taxa were identified, many to taxonomic levels previously unrecorded for aquatic fauna in Arabia. Overall richness was comparable between all habitats sampled. While very little regional information is available for identification of aquatic macroinvertebrates, the combination of regional descriptive information with foreign keys for aquatic
stages has proven to be a valuable approach. Recommendations are made for appropriate levels of classification for the major taxonomic groups, and
references are provided to assist in identification.
