New species of Furculanurida (Collembola, Neanuridae, Pseudachorutinae) from the Luquillo Mountains, Puerto Rico.

A new species of Furculanurida is described and illustrated. Furculanurida bistribus sp. nov. differs from other species of the genus by the presence of three eyes, three setae on the dens, and the white and purple coloration pattern. A key for identification of the world species of the genus is included.

A new Caribbean species of Hylaeanura Arlé, 1966 (Collembola, Neanuridae, Pseudachorutinae).

We here describe a new Collembola species, Hylaeanura emiliae sp. nov., from the Luquillo Experimental Forest in Puerto Rico. We describe H. emiliae sp. nov. as a distinct species based on the enlarged sensilla s3 in antennal segment IV, the absence of modified sensorial setae in abdominal segment IV and the presence of four setae on each dens. An updated key with illustrations for the identification of worldwide species of the genus is included.
