Avicularia aurantiaca
The division of living beings into systematics is a continuous subject of research. The term treated here has become obsolete due to recent research and cannot be reliably assigned to any taxon . The cause can be lost original material (type material) or the material used for the first scientific description lacks identifying features in order to clearly differentiate it from similar types.
Avicularia aurantiaca ( noun dubium ) as a new species of tarantula was described by Stefan Bauer in 1996. Today the species status is questioned because it cannot be scientifically verifieddue to the loss of the holotype . This term is still common among terrarium owners. Spiders that were later referred to as that were also sold under other names such as "Avicularia magdalenae" or "Avicularia bicegoi". A common German name is not known.
anatomy
Spiders that are so called reach a size of five to six centimeters in the female sex, very old animals also reach eight centimeters. The males remain a little smaller at four centimeters. As newly hatched animals, the young are around six to eight millimeters in size (wingspan 15-20 mm). Adult females are uniformly dark brown in color. The front body is a little lighter and glows beige-gold up to the legs when exposed to direct radiation. The legs have yellow-orange leg rings between the segments. The longer leg hair has light-colored tips, which makes the entire animal appear lighter. Adult males are almost black, as are the hairs. The front body and the abdomen have a purple color when exposed to direct light. They have shin hooks (tibial apophyses). When hatching, the young show the typical Avicularia coloration: a dark (brownish) body and pale pink legs with dark tips ( tarsus ). The abdomen has the red and black Christmas tree pattern. Black background with large red areas on the sides. With the fifth to sixth moulting of the young animal (nymph), the legs change color. The legs are now dark and show the light toes.
