Comparison Stylosmilia Milne-Edwards and Haime (1848: 274; 1850: xxvii; Wells 1956) is the closest comparable genus. The subprismatic corallites with apophyses in Lochmaeosmilia differentiates it from Stylosmilia. [details]Diagnosis Corallum phaceloid. Corallites formed by intracalicular budding. Corallites dichotomizing, very small in diameter, elongate, cylindrical or subprismatic in shape, angular, trigonal, quadrangular, hexagonal, or elliptical in cross-section. Corallite wall septo-parathecal with thin epitheca. Corallites occasionally connected by cross tubules. Columella feeble or absent. Septa laminar, usually arranged in less than three cycles with irregularly developed auriculae at the inner edge which may join to form columella. Endotheca thin and tabular [details] Remark Wells (1943, 1956: F398) defined the genus Lochmaeosmilia on the basis of Stylosmilia trapeziformis Gregory 1900, which he designated as type species. Alloiteau (1958: 68) found that Eunomia radiata Lamouroux (1821: 83, pl. 81, figs. 10-11) and Stylosmilia trapeziformis are members of the same genus, as both of them exhibit similar morphological characters, and erroneously declared E. radiata as the type species of Lochmaeosmilia. Wells (1943: 48) interpreted the figures of Stylosmilia trapeziformis given by Gregory (1900: pl. 11, figs. 5-12) as showing extracalicular budding and an epithecal wall, despite Gregory's (1900: 47) description of intracalicular budding. In the type specimen (as seen in other topotypes) there are clear indications of intracalicular budding). Wells (1943, 1956), Alloiteau (1958) and Bendukidze (1982) assigned Lochmaeosmilia to the family Amphiastreidae Ogilvie 1897. The members of this family are characterized by a distinct epitheca, by the lack of a columella (its place being occupied by one large septum projecting into the axial space). Many of the Kachchh specimens show auriculae along the inner edges of the septa which eventually fuse together and give the appearance of a columella. Specimens illustrated by Gregory (1900) also show a columella. However, Gregory (1900: 47) mentioned that the columella is "not very prominent; variable in size in cross sections of corallites". This character, together with the septo-parathecal wall and endothecal elements, refers L. trapeziformis Gregory to the family Stylinidae to which Gregory originally had assigned the species. Wells (1956: F398) also mentioned Lochmaeosmilia belonging possibly to the Stylinidae. [details] |
