Ybyrapora is a genus of spiders in the family Theraphosidae (tarantulas), found in Brazil.
Females have strongly curved, almost non-sclerotized (i.e. non-hardened) spermathecae.
Immature spiders have a central reddish mark with jagged edges running along the centre of the abdomen, surrounded by a dark area connected to similarly dark coloured stripes running across the abdomen.
[2] The genus was erected by Caroline Sayuri Fukushima and Rogério Bertani in 2017 for three species formerly placed in Avicularia which they regarded as distinct, both in their morphology and distribution.
[2] A morphological phylogenetic study in 2017 suggested that the genus is most closely related to Iridopelma, forming a clade with Antillena, Caribena, Iridopelma and Pachistopelma, distinct from Avicularia:[2] Avicularia Antillena Caribena Iridopelma marcoi Pachistopelma Ybyrapora Iridopelma As of March 2017[update], the World Spider Catalog accepted the following species, all transferred from Avicularia:[1] Ybrapora species are found in the Atlantic rainforest of Brazil, from Bahia to the south of Rio de Janeiro.
