  • The family Staphylinidae is second family belonging to the Order Coleóptera, with most (47 744) described species. The rove beetles are insect ecologically significant, carrying out different roles in agroecosystems; in many cases as predators of agricultural pest. Between March of 2007 and October of 2008, samples of these coleopterans were carried out in six coffee agroecosystems belonging to Central Valley of Costa Rica. The sampling consisted in the Quadrat Sampling Method, in this method a wood quadrat (0,5 x 0,5 m) was placed around coffee plants, where litter was collected and subsequent it was sieved and placed into Berless funnels to insect extract. Analyses of the components of biodiversity for the species, were carried out, calculating biological diversity index (Shannon-Wiener), species evenness, Margalef richness, Jaccard similarity index, non-metric multi-dimensional scaling (MDS) and analysis of similarities (ANOSIM) as well. A total of 1406 specimens were captured. Of these, 382 (27,17%) were collected in Palmares, 355 (25,25%) in Tres Ríos Sombra, 212 (15,08%) in Barreal Sol, 183 (13,02%) in Barreal Sombra, 161 (11,45%) in Tres Ríos Sol and 113 (8,04%) in Naranjo. Ten species determined and five undetermined belonging to seven subfamilies were caught. According to the biological diversity analysis, Palmares shows the highest richness of rove beetles in the sampled places
