First described in 2000 by Wanda Wesołowska and Anthony Russell-Smith, it is a very small spider, which is recalled in its species name, a Latin word meaning small, with a carapace typically 0.8 mm (0.03 in) long and an abdomen between 0.8 and 0.9 mm (0.04 in) long.

The spider is generally yellow with a brown patch in the middle of the carapace and a narrow stripe running down the top of the abdomen apart from the black eye field.

Tanzania minutus is a species of jumping spider, a member of the family Salticidae, that was first described by the arachnologists Wanda Wesołowska and Anthony Russell-Smith in 2000.

[2] Wesołowska and Russell-Smith initially allocated the spider to the genus Lilliput, circumscribed at the same time by the same authors and named after the nation in the novel Gulliver's Travels.

[5] 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 in 2015 but the relationship has not been confirmed.

The topside of the abdomen is covered in long thin brown hairs and has a delicate scutum visible in the middle.

[14] It lives in bushland dominated by plant species of the genera Acacia and Commiphora.
