Lenticellaria bisepta Simon, Logan et Mottequin, 2016
Type locality: Tanker-shipwreck near Kodingareng Island (Spermonde Archipelago), Makassar, South Sulawesi, Indonesia (5°06’17.43” S, 119°17’03.92”E).
Depth range: about 30 m
Megerlia echinata (Fischer & Œhlert, 1890)
Diagnosis - (Simon, Logan et Mottequin, in Simon et al., 2016)
Micromorphic brachiopod, wider than long with a semicircular outline in dorsal view. The external surface of the dorsal valve is smooth whereas the external surface of the ventral valve has radial tuberculation. Between the radial rows of tubercles, numerous scales with typical “Gaussian curve” outline are developed in concentric lines. Foramen amphithyrid. Cardinal process and hinge plates absent. Inner dorsal valve floor tuberculate. Short crura developed. Loop, going through a cucullate phase, a “pseudo” annular phase and finally consisting of two simple claws, relatively wide, with sharp tips. Base of the bifid septum unraised. Descending branches absent. Septum on the ventral valve floor partly interrupted in its posterior portion.

Diagnosis - (Simon, Logan et Mottequin, in Simon et al., 2016)
Micromorphic brachiopod with a very variable outline in dorsal view depending on the topography of the substrate to which the specimen is attached. Shell often distorted but sometimes semicircular in outline. External surface of dorsal valve smooth. Ventral valve with radial tuberculation. Between the radial rows very small scales are regularly developed in concentric lines. Foramen amphithyrid. Cardinal process and hinge plates absent. Inner dorsal valve floor tuberculate. Short crura developed. Loop made of two claws relatively narrow and thin with sharp tip and with a clearly raised pedestal. Descending branches absent. Septum on the ventral valve floor partly interrupted in its posterior portion.
