1. Scolymia lacera (Pallas, 1766) Material examined: USNM 53149 (Gulf of Mexico, Florida, USA). Diagnosis: Wells (1964): 381���382, pl. XXII, figs. 5, 6 Distribution: Cura��ao, Bonaire, Jamaica, Cuba, Bahamas, South Florida. In: Wells (1964,1971), Lang (1971), Zlatarski and Estalella (1982) Holotype: lost (no number) Description: Solitary attached corallum varying from concave, slightly flabelloid to discoidal forms, rounded; thick primary septa, wide triangular-shaped dentition (septal teeth numerous, regularly distributed); diameter in adult individuals around 10���12 cm (maximum of about 15 cm); parathecal walls; costae coarsely spined; septa lateral spines are low and concentrated along midline of the dentations, spongy columella usually elliptical. Remarks: According to Lang (1971) ���fleshy Scolymia ��� (S. lacera) shows highly agressive interactions with ���smooth Scolymia ��� (S. cubensis), also attacking other neighboring corals by extruding the mesenterial filaments. Scolymia lacera has been reported in deeper zones being eventually abundant in depths of 30 to 60 m on Jamaican reefs (known bathymetric range: 25 to 140 m). Largest solitary monostomodeal coral in the West Indies. Dentition more regular than that of S. cubensis and S. wellsi., Published as part of Neves, Elizabeth, Johnsson, Rodrigo, Sampaio, Claudio & Pichon, Michel, 2006, The occurrence of Scolymia cubensis in Brazil: revising the problem of the Caribbean solitary mussids, pp. 45-54 in Zootaxa 1366 on page 48, DOI: 10.5281/zenodo.174809, {"references":["Pallas, P.

A comparative morphological and molecular characterization of species boundaries between four species of the Scleractinian genus Psammocora, namely P. digitata, P. haimeana, P. profundacella and P. contigua was conducted. The definition of species boundaries in this genus has been the subject of few studies, in spite of the presence of ambiguous taxonomic distinction, and a revision of the genus has never been undertaken. The multivariate analyses of both descriptive and morphometric characters confirmed the distinction of P. digitata and P. contigua, conversely P. haimeana, P. profundacella and their intermediate morph differentiated on the basis of descriptive morphologic characters only. Morphometric characters alone allowed a less defined distinction between morphs, and morphological boundaries essentially intergraded in a gradient driven by enclosed corallite series characters. The phylogenetic analysis of a portion of the rDNA confirmed the morphological inferences, as P. digitata appears to be a distinct evolutionary lineage. Conversely, the other four morphs, P. contigua, P. haimeana, P. profundacella and their intermediate constitute a polytomic gene pool significantly distinct from P. digitata. Yet, P. contigua is significantly distinct from the other three morphs. Both morphological and molecular approaches suggested that P. haimeana, P. profundacella and their intermediate cannot be considered clearly distinct entities. Hybridization with other species of this genus not included in this study, or recent origin may have contributed to the polyphyly and lack of phylogenetic resolution of P. haimeana, P. profundacella and their intermediate morph. They appear to constitute a single gene pool showing morphological characters encompassing a gradient from the P. haimeana to the P. profundacella morphs. Such morphological variability possibly depends on environmental factors such as light conditions. [ABSTRACT FROM AUTHOR]
