Abstract

The first record for the shrimp genus Aeger Münster, 1839, in America is documented by Aeger hidalguensis, new species, described from Albian–Cenomanian beds of the El Doctor Formation, Muhi Quarry, Hidalgo, Mexico. Reconsideration of Aegeridae Burkenroad, 1963, results in placement of Acanthochirana Strand, 1928, within the family. Aeger hidalguensis is associated with the palinurid lobster, Palinurus sp., which represents only the second fossil record for the genus in America. Specimens collected from the Aptian San Juan Raya Formation, Puebla, allow a more complete description of the mecochirid Meyeria pueblaensis Feldmann et al., 1995, and documentation of sexual dimorphism in the species, the first report of dimorphism in the genus.
