Diagnosis.

Head with no projection on vertex, leg-pairs 6 and 7 without noticeable modifications. Gonopods parallel, distal part of the telopodites crossing. Each gonopod with a large clavate prefemoroidal process ( pf1) reaching the distal part of telopodite (and sometimes accompanied by a smaller one); coxa with a protruding rounded anterior projection and a large coxal process, latter almost of the same size as the telopodite. Telopodite ( T) with a stout stem, distally expanding in three main folds including a horizontal mesal projection accommodating the solenomere ( s) and parasolenomere ( ps). Different from all the other genera of Paracortinidae by the enlarged mesal falcate coxal process and prefemoroidal process, and by the shape of the distal part of the telopodites.

Etymology.

A combination of crassus, meaning fat/stout, referring to the large mesal coxal process and petalum a suffix used in many genera in the order Callipodida .
