The gnathos arms are distinct, sclerotized, curved and apically very narrowly fused with the tegumen, close to the base of the uncus. The base of the broad anal tube with its long sclerotized subscaphium is fused with the gnathos arms and membrane of the fultura superior (which is ventrad of the anal tube).
