"Phialaspis," T. symmondsi
The head-shield and body armor of most species form an almond shape. The armor of T. symmondsi (syn. Phialaspis symmondsi) is shaped like a jet plane or paper airplane, with pointed wing-like crests and a dorsal crest near the posterior end of the armor.
The generic name honors Ramsay Heatley Traquair.
