The variation of the diversity of scorpions in seven fragments of Tropical Dry Forest (TDF) in the Department of Atlántico was determined. The sampling was conducted by fallen leaves hoeing, foliage agitation and manual capture at night with UV light. An effort of two nights and three days was made in each transect. A total of 516 specimens representing seven species, six genera and three families (Buthidae, Chactidae and Hormuridae) were collected. The most diverse and abundant family was Buthidae with four genera and 486 individuals, standing out the species Tityus (Archaeotityus) tayrona whose presence was constant in the seven fragments. The fragment of forest Reserva Campesina La Sierra (R.C.S) presented the greatest diversity with six species, six genera and three families, which is possibly due to the abundance of resources and microhabitats. With the results, the area of distribution of the species Tityus (Atreus) aff. asthenes and Chactas brevicaudatus expanded. In addition, it was found that 60% of the families and 42.8% of the genera reported for Colombia are represented in the Department of Atlántico which indicates that the relics of TDF in this Department maintain a significant fauna of the scorpions registered for the country.

Keywords : Buthidae; diversity; Hormuridae; Tityus (Archaeotityus) tayrona.
