Diagnostic characteristics:
- two dorsal
shields, podosomal and fused opisthosomal and pygidial shields
- posterior margin of podosomal shield is straight, occasionally a slight medial
lobe is present
- opisthosomal shield is longer than wide, but not twice as long as wide
- opisthosomal shield without lateral excavation
- posterior margin of opisthosomal shield is invaginated forming an inverted V
indent, occasionally it is rounded
- anterior margin of opisthosomal shield is straight
- st1 st2 and st3 off the sternal shield
- subapical ventral setal pair on tarsus IV are long heavyset inflated spikes
- six pairs of ventral opisthosomal setae
- four 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
