Two new species of Sminthurididae, Medeiros & Bellini, and Silva, Medeiros & Bellini, from Piaui state, Brazil, are herein described and illustrated. resembles species of the group, like Bretfeld & Gauer, Bretfeld & Gauer, and Bretfeld & Schulz, by its complex male ventral tube without asymmetrical structures or medial process. However, it differs from them by the combination of the male tibiotarsus III with a leaf-shaped IIpe chaeta and a regular IIIpi chaeta, ventral tube with 1+1 chaetae, and the absence cuticular hooks on the furca. resembles its congeners without the nasal organ, especially Ospina & Palacios-Vargas, by the presence of spiniform chaetae at least on the second antennal segment of the females, four serrated spines on tibiotarsus III, and the ventral dens chaetotaxy, but differs from the latter especially by the presence of 8+8 eyes and the shape of the male proximal tibiotarsal organ. To describe both species all Neotropical and all described species were surveyed, presenting notes on both genera, comparative tables, and keys for these taxa.
