- opisthosomal shield without lateral excavation
- posterior margin of opisthosomal shield is rounded, occasionally it is
invaginated forming an inverted V indent
- anterior margin of opisthosomal shield is straight
- st1 st2 and st3 off the sternal shield
- subapical ventral setal pair on tarsus IV are relatively long filamentous spikes with
long flexible tips
- 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
- minute
subposterior pair of dorsal podosomal setae are as long or almost
as long as the longest mesolateral setae
- paranal setae posterior to anal opening, paranal and postanal setae are unequal in
