New families Paragalatheidae and Catillogalatheidae (Decapoda: Anomura: Galatheoidea) from the Mesozoic, restriction of the genus Paragalathea, and establishment of 6 new genera and 20 new species

Two new families of Galatheoidea from the Mesozoic are described. Paragalatheidae encompasses members of Paragalathea and Mesogalathea, as well as two new genera: Discutiolira and Lemacola. The genus Paragalathea is herein restricted to its original definition. New species within the Paragalatheidae established in this paper are: Paragalathea arcella, P. crenarvina, P. ternata, P. vultuosona, Lemacola Jenniferae, L. rossi, L. salia, Mesogalathea macra, M. pyxis, and M. retusa. The new family Catillogalatheidae is described to encompass species from the Late Jurassic and Cretaceous. New genera established within Catillogalatheidae include: Catillogalathea, Tuberosagalathea, Serraphylctaena, and Vasconilia. New species established within Catillogalatheidae are: Catillogalathea falcula, Catillogalathea patruliusi, Catillogalathea purcarenensis, Galatheites aiola, G. diasema, G. obtecta, Hispanigalathea tithonia, Tuberosagalathea antefixa, T. tornatilis, and Vasconilia xystosa. The genus Galatheites is redescribed. Some observations and remarks are made on the preservation of cuticle and ornamentation on galatheoid dorsal carapaces.
