Mictacea is the most recently established order of crustaceans, erected for five species of small shrimp-like animals of the deep sea and anchialine caves.[2]

Description
Mictaceans have a brood pouch (marsupium) and biramous thoracic limbs, but lack a carapace.[3] They have eyestalks but "no functioning visual elements".[4]
History
The existence of animals resembling the Mictacea had been predicted by Frederick Schram in the early 1980s. Two groups of scientists independently discovered the animals in 1985, and, once they learnt of each others work, agreed to work together on the paper describing the new order.[5]
Species
A total of five species are recognised, split between two families:[6]
- Hirsutiidae Sanders, Hessler & Garner, 1985
- Hirsutia bathyalis Saunders, Hessler & Garner, 1985
- Hirsutia saundersetalia Just & Poore, 1988
- Thetispelecaris remex Gutu & Iliffe, 1998
- Thetispelecaris yurigako Ohtsuka, Hanamura & Kase, 2002
- Mictocarididae Bowman & Iliffe, 1985
- Mictocaris haplope Bowman & Iliffe, 1985
