Diagnosis.
In ventral view, the inferior appendages of Agmina complexa sp. nov. form a narrow plate with a posteroapical incision laterally flanged by a row of small setae, similar to those of A. spina sp. nov., A. guttata sp. nov., and A. amieuensis sp. nov. Agmina complexa sp. nov. are easily separated from the above similar species by the much longer and almost oval sternal process in lateral view, and the superior appendages are strongly modified and form a pair of very large, anteriorly curving hooks. Agmina amplexa sp. nov. also have strongly modified superior appendages but A. amplexa sp. nov. has three pairs of more or less mesally orientated hooks instead of a single pair of hooks that are directed anterad in A. complexa sp. nov., as seen in dorsal view.
Etymology.
Named for the complex shape of the superior appendage.

Paratype: New Caledonia - Province Nord • 1 ♂; Mt. Panié, stream at camp; 20.58167S, 164.76472E; 1311 m; 9.xii.2003; Malaise trap; loc#073; leg. KA Johanson; NHRS.
Measurements.
Fore wing length 3.5-4.3 mm (N = 2). Total length of genitalia: 0.8 mm.
Description.
Genitalia: In lateral view, segment IX narrowly triangular, apex located medially; in ventral view anteriorly elongated, U-shaped. Sternal processes, lateral view, with club-shaped, dorsal margin convex, ventral margin straight, apex rounded; in ventral view, robust, slightly diverging, equally wide along their length, apex truncated. Tergum X irregular quadrilateral with concave anterior margin, convex posterior margin, lateral margins almost straight; as wide as high; in dorsal view, mesally fused, triangular with acute apex. Parameres slender, starting before tergum X, in lateral view sigmoid, widening at apex with concave posterior margin; in dorsal view, separated, long, slender, straight, widening along their length, posterior half slightly wider anteriorly, then equally wide along their length, posteriorly abruptly curving lateroanterad, apex hook-shaped directed anterad. Superior appendages, in lateral view, initially triangular, greatly narrowing forming ridged, greatly curved, narrow process with acute apex directed mesad; in dorsal view forming large hook-like structures, with apices greatly curving, directed anteromesad, crossing mesally. Inferior appendages, in lateral view, with posterad orientated single branch, straight with truncate apex with dorsad directed tooth dorsally, ventral margin and apex exceeding margin of sternal process; in ventral view very slender, lateral margins convex, acute, narrow posterior processes at apex. Phallus, in lateral view tubular, straight; in ventral view slightly wider anteriorly, with triangular lateral lobes, tubular.
