Popis:	Nine species, including two new species of decapod crustaceans, are described from the Paleocene Rancho Nuevo Formation, collected from two localities of the Parras Basin, southeast Coahuila state, Mexico. The astacidEnoploclytia gardnerae(Rathbun, 1935) is represented by a pair of large chelae and one cephalothorax. An incomplete nephropid carapace is identified asEnoploclytiasp. Partial specimens of a callianassid and a pagurid are described. One partial carapace representingLinuparus wilcoxensisRathbun, 1935 is described. A new raninid,Macroacaena venturainew species extends the genus into Mexico.Paraverrucoides alabamensis(Rathbun, 1935) is the most abundant species, followed byTehuacana tehuacanaStenzel, 1944 andViapinnixa perrilliataenew species. Taxonomic affinities of this assemblage confirm influence of the Mississippi Embayment, particularly from Paleocene stratigraphic units of Texas and Alabama.
