Two new genera and a new species of schizomids (Arachnida: Schizomida) from Isla de Pinos, Cuba

Abstract

The schizomid fauna of Isla de Pinos (the second largest island in the Cuban archipelago), is revised. A new genus is described to accommodate Schizomus insulaepinorum Armas, 1977 (currently in the genus Luisarmasius Reddell & Cokendolpher, 1995), which is redescribed and fully illustrated according to the modern standards in schizomid taxonomy; its geographical distribution is also updated, with a new locality record. A second new, monotypic genus with a new species is also described from the same geographical area: the residual marble hills of the northeast of the island. As results, the schizomid fauna of Isla de Pinos is now known to comprise two nominal genera and species (both endemic to the island), the Cuban schizomid fauna reaches 13 genera and 57 species (being endemics 10 and 56 of them, respectively), and Luisarmasius is left monotypic and becomes the only genus endemic to Puerto Rico.
