Stegocoelia Donald, 1889

Australian Carboniferous species. Stegocoelia (Stegocoelia) nodosa Yoo, 1988 , from 'Marohn'; Stegocoelia (Hypergonia) elongata Yoo, 1988 , from 'Marohn'; Stegocoelia (Hypergonia) tenuis Yoo, 1988 , from 'Marohn'; Stegocoelia (Hypergonia) sp. A (in this study), from 'Kyndalyn'; Stegocoelia (Hypergonia) sp. B (in this study), from 'Kyndalyn".

Remarks. Stegocoelia is transferred from the Murchisonioidea to Loxonematoidea on the basis of the morphological similarity of the protoconch to Loxonematoidea. Stegocoelia has a tall, smooth sinuated protoconch and dominant spiral cords on teleoconch without a distinct selenizone. In contrast, Murchisonia seems to have a simple protoconch and a distinct selenizone.
