H. L. Clark (1915) changed the spelling of this species to arcystata and 

 stated that acrystata was a typographical error. In the original description 

 (1911), he gave the derivation as from the Greek \KpvaTaTat,, signifying 

 "surrounded with nets": the spelling of the Greek word should have been 

 kpKvoTaToi. Therefore, the original spelling was correct.
