- Abstract
Inventoried to Chironomidae fauna in the southern state of Tocantins, Brazil. Were carried out six collections bimonthly on 45 collection sites with lotic characteristics in 2006. The material was collected manually, at manual sampling in the various environments, where we verified abundance and constancy of Chironomidae. From the collected material was identified 511 specimens mounted on permanent slides. We recorded the occurrence of 30 genera distributed in three subfamilies (Chironominae, Orthocladiinae and Tanypodinae). Orthocladiinae was the most abundant constituting 55% of total identified larvae. Cricotopus was the most abundant, representing 35.20% of the total identified larvae, followed by Thienemanniella 14.85%, Rheotanytarsus 13.65% and Polypedilum 11.90%. The subfamily with the highest number of genera, was Chironominae with 18. The most abundant collection site, was ENP1 with 70 specimens, followed by ENPN15 with 65. The collection sites ENPN14 and ENP1 were those with the greatest number of genera, with 11 genera each, ENP1 had the largest number of accessories genera with six, followed by EN147 with three accessories genera. In this study we did not observed any constant genera. All genera found are new records for the state of Tocantins, and 12, have not yet described species for Brazil.
