Diagnosis.
Agmina touhoensis sp. nov. resembles most other species in the species group, particularly A. bleuensis sp. nov. and A. hamata due to the wide separation of the dorsal and ventral branches of the inferior appendages in lateral view. Agmina touhoensis sp. nov. is distinguished from A. bleuensis sp. nov. by the much longer sternal processes, and a dorsal branch of the inferior appendages that are almost as long as the ventral branches. It is distinguished from A. hamata by the wider superior appendages in lateral view, and the dorsal branch of inferior appendages that is almost straight instead of curving ventrally.
Etymology.
Touhoensis, derived from Touho, the type locality of the species.
Material examined.
Holotype: New Caledonia - Province Nord • ♂; Ponandou Tiôgé River at Kögi, 3.9 km SSW Touho; 20°49.043'S, 165°13.551'E; 25 m; 26.xii.2003; light trap; loc#100; leg. KA Johanson; MNHN.
Measurements.
Fore wing length 4.6 mm (N = 1). Total length of genitalia: 0.6 mm.
Description.
Genitalia: In lateral view, segment IX almost constituting of sternal process only; anterior apex located immediately below mid-height of genitalia; in ventral view anteriorly without incision. In lateral view, sternal processes with small, almost straight dorsal margin, ventral margin pointing into triangular; in ventral view, slender, orientated posteriorly before strongly curving mesally before apex. Tergum X almost rectangular, with pointed anterodorsal corner; in dorsal view, mesally well separate, each forming narrow plate curving inwards, with slightly convex inner margin. Parameres robust, tubular, starting below tergum X and ending at basal 1/3 of superior appendages, hidden behind upper branch of inferior appendages; in dorsal view, originating from transverse bow-like basis; orientated posteriorly, almost parallel, row of short megasetae present immediately after mid-length. Superior appendages, in lateral view, small, with almost straight dorsal margin, ventral margin pointing into triangular; in dorsal view bean-shaped, orientated posterad along their length, except slightly mesally orientated, rounded corners. Inferior appendages, in lateral view, with broad basis and two long posteriorly orientated branches; dorsal branch slightly undulating, ending near basis of superior appendages, apex needle shaped; ventral branch uniformly thick, curving outwards along its length; in ventral view with shield-shaped basis; dorsal branches located laterally of ventral branches, undulating and orientated posterad along their length; ventral branches broad and curving mesally along their length and almost tangential apically; apex narrowly triangular; setae confined to distal two-thirds. Phallus, in lateral view approx. half as long as segment IX, curving downwards at mid-length; in ventral view vase-shaped, with wide rounded basis and narrow posterior half.
