The collection comprises 254 specimens representing 1 superfamily, 2 families, 7 genera, and 9 species. Among these, Clorida decorata Wood-Mason, 1875 and Harpiosquilla raphidea (Fabricius, 1798) are new records for the area. Cloridopsis aquilonaris Manning, 1978, is synonymized with C. scorpio (Latreille, 1828). All nine species are illustrated and a diagnostic key to the species known from southern China between Macau and Hong Kong is provided.

Le mat´ eriel collect´ e inclut 254 sp´ ecimens repr´ esentant 1 super- famille, 2 familles, 7 genres et 9 esp` eces. Parmi celles-ci, Clorida decorata Wood-Mason, 1875 et Harpiosquilla raphidea (Fabricius, 1798) sont signal´ ees pour la premi` ere fois dans cette region. Cloridopsis aquilonaris Manning, 1978 est mis en synomymie avec C. scorpio (Latreille, 1828). Des illustrations des neuf esp` eces, ainsi qu’une cl´ e d’identication pour les esp` eces connues du sud de la Chine, entre Macao et Hongkong, sont fournies. INTRODUCTION The stomatopod fauna of the Chinese coasts has received relatively little sci- entic attention. The principal papers treating the mainland Chinese fauna are those of Schmitt (1931) and Liu (1949), supplemented by Liu (1975) and Liu Ó Koninklijke Brill NV, Leiden, 1999 Crustaceana 72 (1)
