Ybyrapora

Ybyrapora is a genus of spiders in the family Theraphosidae (tarantulas), found in Brazil. Its species were formerly placed in the genus Avicularia.

==Description== Ybrapora consists of species that are smaller than most aviculariines. Females have strongly curved, almost non-sclerotized (i.e. non-hardened) spermathecae. The tibial apophysis (outgrowth) on the first leg is absent or small. Individuals show major colour changes as they mature. 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. These patterns become duller or disappear in adults, particularly females.
