anal papilla

There are two tubular excretory organs, which discharge to the exterior via nephridiopores, on the anal papilla.

The ovipore may be at the end of a modified 'ovipositor' or surrounded by a pair of broad setose anal papillae.

The anal papilla is very short and rounded in females, but is longer and very slender in males.

Other conditions that produce an anal mass include: skin tags, anal warts, rectal prolapse, polyps and enlarged anal papillae.

The type has not yet been dissected but the form of the anal papillae put it with the Apamea species groups with blunt, rounded anal papillae.
