Diagnosis
The male of D. neethlingi gen. et sp. nov. is easily recognized by the field of spines in front of the epigastric fold and the palp with a retrolateral patellar swelling and a broad triangular transparent RTA. The female has a characteristic epigyne in which the ducts in transparency are in the shape of an X with a slight extension where upper and lower parts of X meet.
Etymology
The species name is a patronym for Jan Neethling a pseudoscorpion specialist and the collector of the holotype.
