Cupiennius getazi is a spider from the family of fishing spiders (Trechaleidae). In contrast to the other species of the genus, it has an orange basic color.

features

The body length of Cupiennius getazi can be 22 to 26 millimeters in males and 27 to 38 millimeters in females. The leg span can be over 100 millimeters. The species has a basic orange color. The ventral side of the prosoma is black and that of the opisthosoma is white; the same applies to the underside of the femora . The female also has a central stripe on the upper side of the prosoma and opisthosoma. This is rather brown on the prosoma and has a lighter spot in the middle, on the opisthomosa the stripe has a dark orange hue. There is a lighter stripe in the center.

Similar species

Great wandering spider ( Cupiennius salei )

From other, large species of the genus Cupiennius , especially the great wandering spider ( C. salei ), Cupiennius coccineus and Cupiennius chiapanensis , the species can be reliably distinguished by its coloration characteristics . With Cupiennus getazi , the sternum is always dark, the hips (coxae) mostly dark. The femora are darkly spotted on the underside (this can certainly be distinguished from the otherwise very similar Cupiennus chiapanensis ), but do not have the dark ringing of Cupiennus salei .

Like all species of the genus, some comb spiders ( Ctenidae ), including the dangerous representatives of the genus Phoneutria, are reminiscent of Cupiennius getazi . Even experienced American arachnologists have often confused them with each other when presenting "banana spiders" (spiders imported from Central America to the USA).

Occurrence

The distribution area of Cupiennius getazi includes the rainforests in the countries of Costa Rica and Panama .

Threat and protection

Nothing is known about the protected status of Cupiennius getazi , as the species, like all of the genus, is not listed by the IUCN .

Way of life

Females with grasshopper as prey

Like all representatives of the genus, Cupiennius getazi is predominantly nocturnal and uses the protection of suitable plants during the day, preferably bromeliads and bananas , where the spider takes its hiding place in the moist, often water-filled crevices between the leaf bases. Alternatively, it can also spin several neighboring leaves together with spider silk to form a nook. The species often occurs together with Cupiennus coccineus , also on the same plant. During the night, various prey animals are mainly hunted, including other arthropods and also small vertebrates , such as smaller reptiles and amphibians .

Reproduction

Young female

The reproductive behavior of Cupiennius getazi is similar to that of other representatives of the genus. A sexually mature female attracts a male using spider threads provided with pheromones . When a male senses the presence of a female through the pheromones, he begins a courtship dance by pounding his pedipalps on the undersurface and shaking his opisthosoma. The courtship can take several hours. When the female is ready to mate, she replies by shaking the opisthosoma and also by bringing the male closer. When mating, the male rises on the back of the female and then alternately guides his bulbs into the female's spermathec . Up to three weeks later, the female's opisthosoma swells due to the maturing eggs in it, and her need for food increases. The female then produces a white, spherical and relatively large egg cocoon that is attached to the spinnerets. After about a month, several hundred young spiders hatch from the cocoon, which was previously attached to a "safety net" made by the female. The process is repeated several times and the female makes up to three cocoons. It does not practice brood care. The young spiders grow up within eight to ten months. The lifespan of females can be up to two years, that of males is less.

Systematics

The species was named Cupiennius getazi when it was first described by Eugène Simon in 1891 . Frederick Octavius ​​Pickard-Cambridge renamed the species to Cupiennius griseus in 1901 . Under U. Lachmuth, M. Grasshoff and FG Barth, the spider was given its current name again, which has been retained since then. The previously accepted membership of the genus Cupiennius and Cupiennius getazi in the comb spider family, which had been questioned by Daniele Polotow and Charles Edward Griswold since 2015, was refuted in 2019 by Luis Norberto Piacentini and Martín Javier Ramírez , instead the genus is now part of the family of fishing spiders . Cupiennius getazi is the type species of the genus.

Terrariums

Like some other species of the genus, Cupiennius getazi is also enjoying a certain popularity as a terrarium animal . As a keeper, however, you should simulate the natural habitat of the spider (rainforest) as best as possible and also pay attention to the high speed of the spider.
