Monitore Zoologico Italiano

Dr M. Vannini (Istituto di Zoologia of the University of Florence) sent us to study trapezid crabs collected from live coral, on the southern coast of Somalia during the 1976, 1979 and 1981 expeditions of the Centro di Studio per la Faunistica ed Ecologia Tropicali of the Consiglio Nazionale delle Ricerche of Florence (PARDI, 1 9 7 6 , 1 9 8 2 ) . A new species of the genus Trapezia from that collection is described. The material is deposited in the Museo Zoologico of the University of Florence (MF); the Zoological Museum of Tel Aviv University (TAU); the British Museum of Natural History (BM); the Zoological Museum of Kiel University (ZMK) and U.S. National Museum (USNM). The abbreviation cl. stands for carapace length, cb. for carapace breadth, m. for manus.
