9A70FA7CFFA1FF9BF0A0FB45FB6EFA03.taxon	diagnosis	Diagnosis: The males of I. petiti differ from other Neotropical species, except for Idiops carajas Fonseca-Ferreira et al., 2017, by presenting spines concentrated on the basal half of the retrolateral depression of the palpal tibia, a tibial apophysis with a narrow apical branch in a rectangular shape, and the presence of a lateral lamella extending along the median portion of the embolus (Figure 3 C). It differs from I. carajas in having the subapical portion of the embolus thin and straight (Figure 3 D), and the metatarsus of leg I slightly curved with a small prolateral projection in the apical half (Figure 3 C). Females are distinguished from their congeners, except I. carajas, by having spermathecae with a large trapezoidal base and ducts in a V shape (see Fonseca-Ferreira et al. 2021, Figure 26 L). It differs from I. carajas by its large oval receptacles (Fonseca-Ferreira et al. 2021).	en	Gomes, João Pedro Costa, Santos, Naila Amanda Sousa dos, Almeida, Marlus Queiroz, Cipola, Nikolas Gioia, Morais, José Wellington de (2024): Idiopidae in the Brazilian Amazon: Description of a new species, characterization of an unknown male and expansion of geographic records.
