Resumen:
Icriobranchiocarcinus rodas Vega n. sp., is recorded from lower
Maastrichtian (Upper Cretaceous) Arroyo Grande Formation near the town
of Rodas (Central Cuba). I. rodas Vega n. sp. represents additional
evidence of paleobiogeographic affinities between Chiapas (SE Mexico)
and Cuba, during the Late Cretaceous. The genus Icriobranchiocarcinus
Vega, 2018 in Vega et al., 2018 was erected from the type species
Icriobranchiocarcinus tzutzu Vega, 2018 from the lower Maastrichtian
Ocozocoautla Formation (Chiapas). I. rodas Vega, n. sp. preserves
details of ventral morphology as well as more details of chelipeds not
reported in I. tzutzu, adding to the morphology of the genus.
Icriobranchiocarcinus belong to a family (Lythophylacidae Van Straelen,
1936) that became extinct worldwide during the K/Pg event.
