Bannana is a genus of goblin spiders (family Oonopidae) native to Xishuangbanna prefecture, Yunnan Province, China, where it lives in the leaf-litter of tropical rainforest.

Individuals are pale yellow and unpatterned, and range from around 1.0 to 1.8 mm in body length, with females being slightly larger than males.

Known only from a nature reserve in Xishuangbanna, Bannana belongs to a group of Asian goblin spiders known as the "Dysderoides complex", that ranges from China to Pakistan and south to Indonesia.

[1] Bannana spiders are known from Menglun Nature Reserve, in Xishuangbanna's Mengla County, where they are found in leaf litter of tropical rainforest at elevations around 640 m (2,100 ft) above sea level.

The specific name crassispina is derived from Latin crassus ("thick") and spinus ("bristle"), referring to two thick bristles on the tibiae of male pedipalps, while the specific name parvula, from Latin parvus ("small"), refers to the smaller size of this species.
