說明
Three new species of Astreopora (Hexacorallia: Scleractinia: Acroporidae), from Cenderawasih Bay in West Papua, exhibit morphological innovations for this conservative genus, extant since the Cretaceous. Two species are fully branching, a condition never previously described for Astreopora: Astreopora cenderawasih sp. nov. has dendritic branching, also seen in the confamilial genus Montipora, whereas branches of A. acroporina sp. nov. possess an axial corallite, regarded as the key morphological innovation facilitating rapid diversification and dominance of reefs in the younger, confamilial and most diverse genus Acropora (staghorn corals). We propose that these novel characters may be parallelisms indicating deep familial homologies. The third species, Astreopora montiporina sp. nov., has expansive coenosteum, reminiscent of plating Montipora. The new species form part of the most species rich Astreopora assemblage reported to date, comprising 14 species. The unique tectonic and eustatic history of Cenderawasih Bay may have played a role in the evolution of these new species.

取樣方法
In February 2006, a survey of coral species diversity (herein meaning richness per se, rather than a diversity index) was conducted at 33 sites, each comprising deep (10–40 m) and shallow (<10 m) components in this bay.

方法步驟描述:
- Species present in each site were assessed by two 45-minute surveys conducted using SCUBA (cf DeVantier et al. 1998). All easily recognizable species of Astreopora were recorded. Unknown species and colonies that were difficult to identify in situ were photographed, and representative specimens were collected for microscopic examination at the Museum of Tropical Queensland (MTQ). Identifications made in the field were reassessed using binocular microscopy and reference to type and mentioned specimens of all Astreopora species in MTQ and some on loan, as well as descriptions in Lamberts (1980, 1982), Veron and Wallace (1984) and Veron (2000). For comparison of colony shapes with modern material, fossil types from Vaughan (1919) were examined and photographed in the United States Natural History Museum (NHNM) Washington DC in 2008 and 2009.
