Indo-Pacific coral species belonging to the subfamily Montastreinae Vaughan & Wells, 1943 (Scleractinea-Coelenterata) Part II. The genera Cyphastrea, Leptastrea, Echinopora and Diploastrea

INTRODUCTION In the first part of the study on the Montastreinae (Wijsman-Best, 1977) I have dealt with the genera Montrastrea and Plesiastrea on the basis of material from a wide range of localities in the Indo-Pacific ocean. In the present paper dealing with the remaining genera of the Montastreinae the geographical approach has been extended. This study is based upon collections from Hawaii, Enewetak (Marshall Islands), New Caledonia, Eastern Australia, Indonesia, Western Thailand, the Mascarenes, the Seychelles and the Red Sea (Gulf of Aqaba). In most of these areas locally available collections have been examined as well as material collected by myself, with ecological data. Material from Western Thailand has kindly been given to me on a loan by H. Ditlev; material from the Seychelles has been studied in the Musée Royal de l'Afrique centrale (MRAC), Tervuren, Belgium. Collections from the Red Sea examined are those of Dr. H. Schuhmacher in the Ruhr Universität in Bochum, and of Dr. G. Scheer in the Hessisches Landesmuseum in Darmstadt. 1) The type material studied is housed in the Museum für Naturkunde der Humboldt Universität in Berlin (ZMB), the British Museum of Natural History, London (BMNH), the Muséum National d'Histoire Naturelle, Paris (MNHN), the National Museum of Natural History, Washington D.C. (USNM), the Universitetets Zoologiske Museum, Copenhagen (UZMC), the Tokohu Imperial University, Sendai, Japan (TIU), the Yale Peabody Museum, New Haven (YPM), University of Glasgow (Gl). Thanks are due to the keepers in charge of the coral collections of the different museums and institutes.
