Brazil is one of the countries with the largest diversity of spiders in the world. However, estimates regarding the real diversity of these animals are incipient in the Northeast, especially in the state of Maranhão. A total of 543 specimens of ground spiders were collected in two phytophysiognomies of the cerrado biome (gallery forest and cerrado sensu stricto) located in the Municipal APA of Inhamun, Caxias, Maranhão. We identified 23 families, 37 genera and 43 species (Araneomorphae infraorder), and most of the species found are recorded being for the first time for the state of Maranhão. The families Corinnidae and Oonopidae exhibited higher species richness, whereas the family Zodariidae showed the largest abundance of individuals. The most abundant species in this study were Leprolochus birabeni and Corinna sp.1.
