1) Mc Intosh suggested this species to be a young sjiecimen of Opliiodromus rittatus. 



2) I cannot agree with Augener's suggestion, that Irma ïimicola Will, from Ceylon should 

 be identical with this species, because Willey clearly states „repeated examination failed to reveal 

 any trace of a tentaculum impar." Perhaps it may belong to the genus Castulia.
