Resumen:
The blind fossil amphipod, Caecorchestia bousfieldi, Hegna and
Lazo-Wasem, new genus and species, is described from the lower Miocene
Campo La Granja amber mines in Chiapas, Mexico, based on more than 130
specimens in diverse states of preservation. It is the second amphipod
species to be described from Chiapas amber. C. bousfieldi belongs to the
Talitridae, a family of amphipods that have successfully colonized
terrestrial habitats. Exactly how fully terrestrial Caecorchestia
bousfieldi was is unclear, and its blindness likely indicates that it
occupied a cryptic habitat. A review of the amphipod fossil record is
given which demonstrates that the amphipods first appeared as fossils in
the Eocene.
