Fossils reveal a high diversity of the staghorn coral genera Acropora and Isopora (Scleractinia: Acroporidae) in the Neogene of Indonesia Author Santodomingo, Nadiezhda Author Wallace, Carden C. Author Johnson, Kenneth G. text Zoological Journal of the Linnean Society 2015 2015-11-18 175 4 677 763 http://dx.doi.org/10.1111/zoj.12295 journal article 10.1111/zoj.12295 0024-4082 5339562 ACROPORA FLORIDA GROUP Diagnosis Colonies usually hispidose. Radial corallites large, appressed tubular with thickened, lip-like lower wall, round calices, evenly sized. Radial and axial corallites make equal contribution to the branch diameter. Coenosteum on radial corallite walls costate or reticulocostate and between radial corallites reticulate with little development of simple spinules ( Wallace, 1999 ). The two extant species Acropora florida ( Dana, 1846 ) and Acropora sarmentosa ( Brook, 1892 ) occur subtidally, and A. florida is one of the most commonly distribut- ed species on modern Indo-Pacific reefs ( Wallace, 1999 ; Wallace et al ., 2012 ). Four species were recognized among the fossil specimens from Indonesia .
