Diagnostic characteristics:
- two dorsal shields, podosomal and pygidial shields
- posterior margin of podosomal shield is trilobed
- poorly defined sternal shield
- subapical ventral setal pair on tarsus IV are relatively long strong spikes with a
rounded terminus
- four pairs of ventral opisthosomal setae
- three pairs of mesolateral setae
- mesolateral setae all approximately equal in length, there are not two pairs
of setae that are twice as long as another setal pair
- subposterior
pair of dorsal podosomal setae are as long or almost
as long as the longest mesolateral setae
- long seta with frayed tip dorsally on tarsus I apical margin
- paranal setae posterior to anal opening, and postanal seta absent
- pygidial shield is sometimes entire and sometimes in two fragments with
subposterior setal pair on the fragments
