Resumo: The 629 Geophilomorpha collected within 12 months in the soil (0-7 cm depth) of a primary upland forest (24 + - 16 individuals/m2/month on average) and of a secondary upland forest (94 + - 28 ind./m2 /month on average) near Manus (Brazil) comprised 7 and 8 terricolous species respectively. Only three species were common to both forest types. In the primary forest, the Schendylidae (3 spp.) represented 57%, and in the secondary forest, the Geophilidae (4 spp.) 82% of all geophilomorphs. The correlation found between the monthly abundance of Hyphydrophilus adisi (Geophilidae) and the humidity of the soil indicated that this eudominant and most probably plurivoltine species of the secondary forest (71 + - 29 ind./m2/month on average) is xerophilus. Additional studies showed that the Geophilomorpha represented 0.1-0.3% of the total arthropods extracted from the soil (0-14 cm depth) in three different upland forest types in Central Amazonia. Between 65 and 91% (48-72 ind./m2/month) of the total geophilomorphs were obtained from the upper 7 cm of the soil during the dry season and 44-100% (29-91ind./m2/month) during the rainy season, compared to the subsoil (7-14 cm depth).
