|Type||Glyphocyphus ataxensis Cotteau, 1886, p. 725, by original designation.|
|Classification and/or Status||Camarodonta; Glyphocyphidae|
|Remarks||Close to Ambipleurus but differing in the degree of test sculpturing developed. In Ambipleurus there are large wedge-shaped depressions on either side of the primary tubercle separating successive plates in both ambulacral and interambulacral zones. In Rhabdopleurus there is a small triangular pit beneath each primary tubercle.
