A new species of Theraphosidae, genus Psalmopoeus Pocock, 1895 is described from the Chocó region of Ecuador, Psalmopoeus pristirana n. sp. (male and female). The identity of the female of the recently described Psalmopoeus satanas Peñaherrera-R. & León-E., 2023 is discussed. Images of Psalmopoeus ecclesiasticus Pocock, 1903 are given for comparison and a distribution map of all Ecuadorian Psalmopoeus species is presented.

Two novel species of Pocock, 1895 are described from the north-western and central-western slopes of the Cordillera Occidental of the Andes mountain range in Ecuador. The new species are easily differentiated from other congeners of by spermathecae and male palpal bulb morphology and a comparatively distant distribution to the type localities of the geographically nearest known congeners. The diagnosis of Pocock, 1093 is revised and updated, considering the novel species and observations on spermatheca of this species.

The genera Psalmopoeus Pocock, 1895, Tapinauchenius Ausserer, 1871 and Pseudoclamoris Hsser, 2018 are revised and cladistics analyses carried out including most species of these genera. In order to test the monophyly of Aviculariinae and Psalmopoeinae, species of all genera in these two subfamilies were included, as well as of Harpactirinae, Selenocosmiinae, Theraphosinae, Stromatopelmatinae, Ischnocolinae, Schismatothelinae, Poecilotherinae, and a barychelid was used to root the cladogram. The matrix with 50 terminal taxa, 1 continuous and 85 discrete characters was analysed with TNT 1.

The genus Lamarck, 1818 is revised and all species are rediagnosed. The type species, described as Linnaeus, 1758, is the oldest mygalomorph species described and its taxonomic history is extensive and confusing. Cladistic analyses using both equal and implied weights were carried out with a matrix of 46 taxa from seven theraphosid subfamilies, and 71 morphological and ecological characters.
