– lateral excavation of the posterior portion of the opisthosomal shield
– posterior margin of opisthosomal shield is invaginated forming an inverted V indent
– anterior margin of opisthosomal shield is straight
– st1 st2 and st3 on the sternal shield
– subapical ventral setal pair on tarsus IV are relatively long strong spikes
– five 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
