Endemic to South Africa, the species lives in the mountains of KwaZulu-Natal and Limpopo.

The female has a large epigyne and spherical spermathecae at the end of its short seminal ducts.

[3] They allocated it to the genus Tanzania first circumscribed by Ahmet Ö. Koçak and Muhabbet Kemalin in 2008.

[5] The species is named for a Latin word that can be translated 'very small', and refers to the size of the spider.

[4] In Wayne Maddison's 2015 study of spider phylogenetic classification, the genus Tanzania was placed in the tribe Euophryini [6] This is a member of the clade Saltafresia.

[8] Junxia Zhang and Maddison speculated that it may be in a clade with Thyenula but that relationship has not been confirmed.

Its carapace, the hard upper part of the cephalothorax, is moderately high with a large flat area and sharp slope to the rear.

There is a meandering sperm duct inside the bulb and a relatively small thin looping embolus that sticks out of the top which is accompanied with an additional spike.

The epigyne, the external part of the copulatory organs, is large and marked by two rounded depressions.

Its copulatory openings lead to short seminal ducts and spherical spermathecae, or receptacles.

The first specimen to be described was found in eMakhosini Ophathe Heritage Park in 2008 at an altitude of 500 m (1,600 ft) above sea level.
