Diagnosis.
Agmina tuberosa sp. nov. resembles many other Agmina species in having large, oval superior appendage, but is distinguished from other species by the large inferior appendages, each with a long dorsal and short ventral branch in lateral view, and the sternal processes reaching to half length of the inferior appendages. The genitalia are similar to those of A. semiovale sp. nov. from which it is distinguished by the presence of a row of teeth-like megasetae on the mesal margin of each paramere in dorsal view.
Etymology.
Tuberosa, from Latin, meaning potato, named for the superior appendage being potato-shaped in lateral view.

Description.
Genitalia: In lateral view, segment IX widely rounded anteriorly, apex located dorsally; in ventral view anteriorly widely U-shaped. Sternal processes, lateral view, with apex not exceeding posterior apex of tergum X, narrowing along their length, curved ventro-posteriorly at mid-length; in ventral view, slender, straight, slightly diverging along their length. Tergum X smoothly convex dorsally, in lateral view longer than high; in dorsal view, mesally separate, axe-shaped with straight inner margins. Parameres robust, starting before tergum X, long, narrow; in lateral view running parallel with dorsal margin of segment IX, X, and superior appendage, ending before apex of superior appendage; in dorsal view, separated and narrowing along their length, each with truncate apex, inner margin with row of megasetae. Superior appendage, in lateral view, large, oval, with posterad spine-like mesal process present on ventromesal margin exceeding the main branch posteriorly; in dorsal view uniformly narrow, running almost parallel, slightly curving inwards towards blunt apex. Mesal processes straight, orientated slightly mesally. Inferior appendage with posterad orientated long dorsal branch slightly dorsally curving at acute apex; dorsal branch widely separated from short, triangular, ventral branch; in ventral view large, wide, oval, with posterad orientated dorsal branches, ventral branch forming central lobe. Phallus, in lateral view as long as segment IX, slender and slightly curving downwards; in ventral view uniformly tapering along its length.
