The genus Antillobisium is restricted to Cuba . All three known species of the genus are strongly adapted troglobites and, because of their geographical isolation, can be considered relictual. The closest genus within the subfamily Bochicinae is Troglobochica Muchmore, 1984 , which is endemic to Jamaica . These two genera share the presence of a well-developed venom apparatus in both chelal fingers, a cheliceral rallum with at least one blade reduced in size and lacking denticles, trichobothrium ib in a basal position on the dorsum of the chelal hand, the absence of eyes and the lack of accessory teeth on the chelal fingers. However, there are evident differences between both genera. Unlike those of Antillobisium , the species of Troglobochica have the pedipalps mostly smooth, the pedal arolia shorter than the claws, trichobothrium ist distinctly proximad of est and the distal and basal blades of the rallum reduced to tiny spinules ( Muchmore 1984 ).
