Andreolepis petri Märss, 2001

The spine and head platelets are covered with elongate tubercles or short ridges. Scales are elongate or deep rhomboidal and flattened; the free field carries up to nine nearly parallel ridges each terminating with a spike, or the posterior margin is uneven; ridges are separated from each other by very narrow grooves. Overlapped and overlapping areas are well developed. Antero-dorsal process of the base is relatively long; viscerally occurs a dorso-ventrally directed keel.
