Psalmopoeus reduncus is a species ofarboreal tarantula from Costa Rica . It is rarely kept in terrariums. It was described in 1880 by the German arachnologist Ferdinand Karsch as the Tapinauchenius species. The species Psalmopoeus maya described by G. Witt in 1996wassynonymouswith P. reduncus in 2008.

features

Psalmopoeus reduncus is a smaller member of the genus Psalmopoeus . The spiders are built compactly. The basic color is chocolate brown to black. The carapace is lighter than the rest of the body and, depending on the light exposure, is light brown to gold in color. In the holotype male, the carapace is 12 millimeters long and 12 millimeters wide, in the holotype female it is 16 millimeters long and 14 millimeters wide. Due to the strong and dense hair, the males appear larger than the females. The underside of the male including the foremost pair of legs and the femora of the button is colored velvet brown in the male. The underside of the female including the two front pairs of legs and the buttons up to the patella and tibia is velvet black. The tibial apophyses of the male are strongly curved and flat. They have a sharp and serrated leading edge. “Reduncus” is Latin and means “hunched back, curved in or out” and thus alludes to the tibial apohyses.

The nymphs and young animals are colored differently than the adult animals. Psalmopoeus redunucus does not resemble in any stage of development that of the species Psalmopoeus pulcher, which coexists in Panama .

behavior

The animals spin living tubes in tree crevices or similar hiding places. If the dwelling is close to the ground, the animals also dig into the ground. The excavated substrate is then brought in front of the entrance and secured with spider silk. In the event of disturbances, the spiders react very quickly and hide quickly.

The mating in captivity is not aggressive. After about four to six weeks, the female builds a cocoon with about a hundred eggs. Sometimes the females build a second cocoon without mating again, which, however, contains fewer eggs. If there is enough food, the spiderlings grow very quickly and are sexually mature in two to three years.

Systematics

In 1996 Gunther Witt described a new type of Psalmopoeus in Panama as Psalmopoeus maya . The main differences to Psalmopoeus reduncus were the darker color and the more northern distribution area. During an expedition in 2008, Ray Gabriel found a juvenile Psalmopoeus reduncus at the Lost & Found Eco Lodge in Panama , which has the same coloration as P. maya . Gabriel caught darker specimens of P. reduncus earlier . Since neither the color nor the place of discovery are valid taxonomic features to differentiate between tarantula species, he rejected the species status of P. maya .
