| Kochummen, K.M.; Wong, K.M.. |
| A new species, Alstonia undulifolia Kochummen & Wong, is described from the Malay Peninsula. Two sections of the genus occur in the Malay Peninsula, Alstonia sect. Monuraspermum Mon. and Alstonia sect. Alstonia, the latter being the correct name for what was previously known as sect. Pala (Adr. Juss.) Benth. Various characteristics, including growth architecture, are examined for their usefulness in distinguishing these two sections of the genus. In comparing A. angustiloba Miq. and A. pneumatophora Berger, both of which have not been properly differentiated by characteristics of the reproductive organs, A. pneumatophora var. petiolata Mon. is reduced to synonymy under A. angustiloba. A key to the seven species of Alstonia native to the Malay Peninsula... |

| West Indian molluscs have been studied by the Department of Malacology of the Zoological Museum Amsterdam for many years. Recently new material collected by Brother M. ARNOLDO (A. N. BROEDERS) and Dr. P. WAGENAAR HUMMELINCK became available which was studied by the second author. During 1982 several West Indian islands were visited by the first author, and mollusc samples were taken on the islands Puerto Rico, St. Martin, Aruba, Curaçao and Bonaire. Material was collected in various biotopes, from the littoral zone down to about 50 m. Most of the micro-molluscs were sorted out from coral sand. In a sample, taken at 45 m depth off Bonaire, some interesting species were found. In this article we will describe a new species, belonging to a new genus, from... |

| A revised key to the subfamilies, tribes and subtribes of the Cetoniidae (Coleoptera: Scarabaeoidea) is presented. Comments are given on the classification implied by the key, which includes several redefinitions. All the known genera (ca. 510) are listed under their tribe or subtribe, the position of several being different from that in Schenkling's catalogues (1921, 1922). References to recent synoptic literature are given. Eighteen new subtribes are proposed, the majority in the tribe Cremastocheilini. One new tribe is proposed, the Platygeniini. Attention is drawn to various new and neglected synonymies, original spellings, and other nomenclatural matters regarding family-group and genus-group names. The position of many genera is briefly discussed.... |

| Doesburg, P.H. van. |
| A new species, Zanchius stami Van Doesburg (Insecta, Heteroptera, Miridae, Orthotylinae) from Syria, Deir-ez-Zor, is described and illustrated. Late eggs taken from the female abdomen have a peculiar chorionic process. It was found living (predaciously?) on cotton plants. It is compared with the closely related Z. alatanus Hoberlandt, 1956. Type specimens are deposited in the Rijksmuseum van Natuurlijke Historie, Leiden, two paratypes in the Národní Muzeum, Praha. |

| The genus Rissopsetia Dell, 1956 (type species R. maoria Dell, 1956, by orginal designation) is recorded for the first time from the West Indies. An hitherto undescribed species was found in beach-sand from two widely apart localities in the Caribbean Sea. The genus is characterized by small to minute shells, which are thin, sculptured with axial ribs and many spiral lirae. The protoconch is heterostrophic and immersed. Aperture with complete peristome. |
