|Etymology||Explaining the derivation of his new name, Mocquard (1890:130) described the distinctive angled aspect of the caudal crests and remarked ‘‘pour cette raison, nous imposons le nom générique de Pelturagonia.’’ Pelturagonia is a feminine Latin noun in the nominative singular derived from the feminine Greek words pelte meaning shield and gonia meaning angle.|
