[edit]

Tetragnatha keyserlingi is widely distributed from Central America, the Caribbean, and Brazil across Africa, Korea, China, India to the Philippines, New Hebrides, and Polynesia.[2]

In Africa, it is known from Botswana, Zambia, and South Africa.[3]

Within South Africa, the species has been recorded from five provinces, including four protected areas, at altitudes ranging from 47 to 1673 m.[3]

Conservation

[edit]

Tetragnatha keyserlingi is listed as Least Concern due to its wide geographical range. The species is protected in reserves such as Ndumo Game Reserve in South Africa. There are no significant threats to the species.[3]

Name

[edit]

T. keyserlingi is named after Baltic-German arachnologist Eugen von Keyserling (1833-1889).

Taxonomy

[edit]

The species was reviewed by Okuma and Dippenaar-Schoeman in 1988 as T. maxillosa, but in 2019 Castanheira and colleagues synonymized T. maxillosa with T. keyserlingi. It was originally described from Java by Simon in 1890. Both sexes are known.[3]
