A water mite species new to science is described after a male very unusual in shape, collected in the state of Mato Grosso, Brazil. The specimen is obviously a representative of the family Limnesiidae, but differs from all other limnesiids in the fourth leg very unusual in shape, and from most members of the family also in the absence of Cxgl-4 and in a male genital field with movable genital flaps. In view of these particular character states, a new genus, Spinilimnesia n. gen., subfamily, Spinilimnesiinae nov. subfam. are proposed in the system of water mites.
