The macrobenthic fauna of a humid tropical zone water reservoir was investigated from January to December 2002. Benthos was obtained using an improvised Surber Stream Bottom Sampler. Three phyla of macrobenthos (Arthropoda, Mollusca and Annelida) prevail in the reservoir, with quantitative variations. A total of 1,279 macrobenthic animals were recorded. The Arthropoda was represented by larvae of five genera of insects, with a total of 644 (50.4 %), while Mollusca was represented by two genera with a total of 165 (12.9 %), and Annelida by three genera, with a total of 470 (36.7 %) of the benthos. There was significant difference (P<0.05) among the phyla populations of the benthos.
