Abstract
Three new species are described: Pseudofabriciola quasiincisura from Belize, P. peduncula from Papua New Guinea, and P. sofla from the Gulf of Mexico off Florida. The total number of species in the genus is increased to 11. Pseudofabriciola quasiincisura and P. peduncula are intertidal, whereas P. sofla is from 26 m depth. An additional species from the Gulf of Mexico off Florida (88m depth), known only from a single specimen lacking the branchial crown, is described briefly but not named. Pseudofabriciola sofla and the unnamed species were originally described by Uebelacker (1984) as Fabricia sp. A. An emended definition for Pseudofabriciola is provided. Cladistic relationships of the species described herein are evaluated relative to others in the genus. The depth distribution of Pseudofabriciola, which displays the greatest known range within the Fabriciinae, is also re-examined.
