A reconsideration on Miocene Munididae of Japan, with a description of a new species of <i>Trapezionida</i> (Decapoda, Anomura, Galatheoidea)

Abstract From re-examination of the type and additional specimens of Munida nishioi Karasawa, 1993 and Kazuoia ogaensis Hatai and Kotaka, 1970 from the Miocene deposits of Japan, both species are assigned to Grimothea Leach, 1821 [1820] of the squat lobster family Munididae Ahyong et al ., 2010. The revised diagnosis and description are given for Grimothea nishioi (Karasawa, 1993) new combination and Grimothea ogaensis (Hatai and Kotaka, 1970) new combination. The monotypic genus Kazuoia Hatai and Kotaka, 1970 becomes a junior subjective synonym of Grimothea . Trapezionida chiyoensis new species is described from the lower Miocene of central Japan. These species represent the first records of Grimothea and Trapezionida Macpherson and Baba in Machordom et al ., 2022 recognized as fossils.
