Nine new genera, 24 new species, and two new combinations within the Munidopsidae are detailed within this paper. New genera established in this paper are: Ambulocapsa, Ankylokypha, Aulavescus, Bullariscus, Cracensigillatus, Culmenformosa, Octoeurax, Pegomyrmekella, and Vetoplautus. New species established in this paper are: Ambulocapsa altilis, Ambulocapsa bachmayeri, Ambulocapsa novacula, Ambulocapsa sentosa, Ankylokypha parabola, Aulavescus exutus, Aulavescus tectus, Bullariscus arcuotorus, B. gibbernodus, B. patruliusi, B. triquetrus, Culmenformosa glaessneri, Culmenformosa nephelepera, Culmenformosa triastrixosa, Cracensigillatus gracilirostrus, Cracensigillatus prolatus, Gastrosacus aequabus, G. levocardiacus, G. limacurvus, G. pisinnus, G. torosus, Octoeurax acaresprora, Pegomyrmekella chaulia, and Vetoplautus latimarginus. New combinations in this paper are: Gastrosacus ubaghsi (PelseneeR, 1886) and Cracensigillatus acutirostrus (moeRicke, 1889). Additionally, the genus Galatheites balss, 1913, is reinstated. Lectotypes are designated for Cracensigillatus acutirostrus, Galatheites zitteli, Gastrosacus meyeri, Gastrosacus wetzleri, and Paragalathea verrucosa. Munitheites Lőrenthey ( in Lőrenthey & B eurLen, 1929) is reassigned to the Pylochelidae within the Paguroidea. A standard terminology for the fossil munidopsids is proposed within this work in order to simplify the diagnoses and descriptions. Two diagnostic keys using dorsal carapace characteristics are provided to distinguish between the families within the Galatheoidea and the genera within the Munidopsidae using characters available in fossils.
