Type species.

Arianula haxairei Herbin, 2012.

Diagnosis.

Arianula is the only other mimallonid genus besides Adalgisa which has irregularly scattered hyaline patches on all wings. However, Arianula is easily recognized by the alternate configuration of these hyaline patches, such that there are fewer patches on the forewing than in Adalgisa , with the most apparent patch being between Rs4 and M1 (conversely in Adalgisa , the most apparent patch is between Rs2 and Rs3); and a unique trio of rectangular patches on the hindwing between M3, CuA1, and CuA2, not observed in this arrangement in Adalgisa .

Apomorphies.

(1) Bizarre claw-like valvae each similar in size to the tegumen + uncus, giving the overall genitalia a triangular appearance (Fig. 17a); (2) Phallus weakly sclerotized, tube-like (Fig. 17b), with elongated narrow juxtal process dorsal to phallus, which itself terminates in a multi-pronged, spined upward curved claw.
