Ybyrapora sooretama ( Syn . : Avicularia sooretama ) is a species of spider fromthe tarantula family (Theraphosidae). It was first described in 2009. The species was named after the Sooretama nature reserveand is very likely endemic there . It may be threatened by human changes in its natural habitat, such as illegal logging and smuggling.
distribution
The distribution area extends from the southernmost tip of the state of Bahia to the south of Rio de Janeiro . It is the southernmost known range of spiders from the subfamily Aviculariinae . The area is about 100 kilometers wide and 1000 kilometers long. The total area is around 39,000 square kilometers. It is possible that this species of spider is rarely found there.
features
In this species of spider there is a clear sexual dimorphism in color. The males have a dark brown basic color. The carapace is dark brown in color. It is lined with light brown hair. The legs and buttons are colored dark brown. The fermora of the legs and buttons are colored even darker than the rest of the limbs. The whole body is covered with longer light brown hair that has a pink sheen. The opisthosoma has reddish hair on the sides and a wide black stripe in the center that runs from the transition to the carapace to the spinnerets.
The females, like the males, have a brown carapace that is lined with light brown hair. The extremities have a brown basic color with longer light brown hair with a pink tinge. The sternum, labium, the underside of the maxilla and the coxa are brown. The leg links have pink rings on the femora, tibiae and metatarses. The opisthosoma is light brown on the sides and has a broad, brown, zigzag-shaped stripe in which a red stripe with zigzag edges is embedded. This pattern runs from the transition to the carapace to the spinnerets.
The coloration of the adult female resembles the coloration in juvenile stages up to a leg span of six centimeters. From later stages of moulting the females get a light brown basic color. The opisthosoma becomes dark brown and the abdominal markings that were conspicuous in earlier stages can still be seen in the form of two diffuse dark stripes. The spiderlings of the related species Ybyrapora diversipes and Ybyrapora gamba are also similar . Ybyrapora sooretama , however, has a shorter red stripe on the opisthosoma and does not reach the upper edge at the transition to the carapace, as is the case with the other two species. This species also lacks the orange dots on the tarsi and metatarsi, which in Ybyrapora diversipes are reminiscent of Psalmopoeus irminia .
The male becomes about three centimeters long (bite claws to spinnerets) with a leg span of up to ten centimeters. The females reach a body length of five centimeters with also about ten centimeters leg span.
