Diagnosis.
In lateral view of the genitalia, A. scopula sp. nov. is similar to both A. ninguana sp. nov. and A. hexacantha in the very broad inferior appendages, each with a dorsally curved ventral branch, and presence of a group of mesally orientated megasetae in the central part of the mesal face of the superior appendages. Agmina scopula sp. nov. is distinguished from both A. ninguana sp. nov. and A. hexacantha by the clearly broader sternal processes in lateral view, more strongly curve of the ventral branch of the inferior appendages, and the more convex margin of the superior appendage.
Etymology.
From Latin scopula (noun, feminine), meaning brush. Referring to the mesally orientated setae at the inner margin of each paramere.

Description.
Genitalia: In lateral view, segment IX narrowly rounded anteriorly, apex located at mid-height of genitalia; in ventral view, anterior incision widely U-shaped, with slightly mesally orientated anterior corners. Sternal processes, lateral view, with large, oval, slightly deeper convex ventrally than dorsally; mesal processes exceeds apex; in ventral view, basally wide, tapering and curving inwards along their length. Tergum X sharply pointing dorsally, higher than long in lateral view; in dorsal view, mesally separate, each forming short lobes with mesally pointing anterior corner. Parameres weakly developed, starting at lower basis of tergum X; in lateral view, bending upwards and with downwardly curving rounded apex; in dorsal view, almost invisible, with group of stout, antero-mesally orientated megasetae. Superior appendages, in lateral view, large, oval, slightly deeper convex ventrally than dorsally; mesal processes exceeds apex; in dorsal view, narrowly parallel-sided and curving inwards along their length, smoothly convex lateral margins; apex with stout, finger-like spine pointing mesally. Inferior appendages, in lateral view, with basal half of ventral margin almost straight, distal half uniformly convex; dorsal branch orientated strictly upwards, widely triangular, with concave posterior margin ending in well separated ventral branch; ventral branch wide at base, tapering and curving upwards along its length, with acute apex; in ventral view, with large central plate being approx. as long as wide, with angled lateral margins and triangular anteriorly; posteriorly with pair of long, widely separated processes orientated posteriorly along their length. Phallus, in lateral view approx. as long as segment IX, straight; in ventral view, triangular with rounded anterior margin and pointed posteriorly.
