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
