Goniasma
Taxonomy
Goniasma was named by Tomlin (1930) [Sepkoski's age data: C Tour P Dora Sepkoski's reference number: 797,1130]. It is the type genus of Goniasminae.
It was reranked as Murchisonia (Goniasma) by Reed (1944); it was reranked as Stegocoelia (Goniasma) by Batten (1995).
It was assigned to Murchisonia by Reed (1944); to Stegocoelia by Batten (1995); to Goniasmidae by Nützel and Bandel (2000); to Murchisoniidae by Knight et al. (1960), Pan and Erwin (2002); to Archaeogastropoda by Sepkoski (2002); to Orthonemidae by Bandel (2002); to Goniasmatinae by Nützel and Pan (2005), Nützel and Ketwetsuriya (2016); and to Goniasmatidae by Bouchet et al. (2005), Mazaev (2015), Ketwetsuriya et al. (2020).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. L. Batten 1995 | As discussed above, I believe the characters that separate the other subgenera of Stegocoelia apply equally to this subgenus. The generic features of a highspired, turreted shell with a pronounced midwhorl to low whorl periphery with a selenizone located near the periphery apply to this subgenus. The distinctive subgeneric feature which serves to separate S. Goniasma from S. Hypergonia, for example, is the placement of the selenizone just below the periphery. |
