Zygometis is a genus of spider in the family Thomisidae described by Simon in 1901, containing the sole species Zygometis xanthogaster, or the milky flower spider or white flower spider, with a distribution from Thailand to Australia (including Lord Howe Island).

They are cream-white in colour, with brownish-red lines on the cephalothorax and abdomen.

[2] This coloration help them camouflage onto white flowers to ambush their prey.

[2] In Australia, they live from coastal forests to semi-arid areas.

[4] They are "too small" to harm humans, and prey on insects by ambush.
