Remarks.
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
).
