Abstract: TPhe caridean family Eugonatonotidae contains a single genus and which is represented by the sole extant species Eugonatonotus crassus (A. Milne Edwards, 1881). Several specimens of this species were obtained during the last four years of decapod crustacean survey in Taiwan. This report adds this decapod crustacean family to the marine fauna list of Taiwan. The morphological characteristics of this species is briefly described and its coloration is illustrated. Following up with our previous works on caridean shrimps (Chan and Yu 1985，1986’ 1987)，the differences at the abdominal pleura and sternites between the sexes in this species are discussed.
