A new West-Indian species of Timea is described and compared with all other Caribbean, Atlantic and Mediterranean members of the genus. Timea micraster n.sp. has a surface system of furrows with elevated sides, not known from other congeneric species and has the tiniest asters known in the family. These asters are of unusual shape but comparable to known species of Timea. The large aster-category has unique cylindrical processes on top of conical rays.
