Easily recognized by their posterior spinnerets which are as long or longer than their abdomen. (1) They have long legs and flattened bodies (5).
Range
Tropical and subtropical. Only one species, Neotama mexicana, occurs in the US and only in Southern Texas. (4)(1)

Two other species known from FL.

Murricia uva, an introduced central African species that is known in Florida from two specimens, one each from Broward and Miami-Dade counties. Further documentation would definitely be welcome. Incidentally, Yabisi habanensis is only known from the Keys.
… Dr.Salticid, 16 December, 2013 - 7:24am
Habitat
Active at night, they position themselves head-down on tree trunks and stone walls where their cryptic coloration conceals them. (1)(4)
Remarks
When prey approaches, the spider quickly runs circles around it, spinnerets toward the prey, covering it with silk. Once covered and securely fastened down, the prey is bitten and consumed. (1)(4)
