Agmina caraffa sp. nov. Figs 110-114

Diagnosis.

Agmina caraffa sp. nov. is distinguished from all other Agmina species in the presence of a pair of long, slender and curving parameres, each armed with tubular megasetae at the meso-ventral face of the posterodorsal apex; and a perfect triangular superior appendage in lateral view.

Etymology.

Named for the carafe-shaped phallus in lateral view.

Material examined.

Holotype: New Caledonia - Province Sud • ♂; stream crossing Nouméa-Yaté road immediately W of turnoff to Rivière Bleue Reserve; 22°10.191'S, 166°44.474'E; 162 m; 22.xi-4.xii.2003; Malaise trap; loc#040; leg. KA Johanson; MNHN.

Measurements.

Fore wing length 3.2 mm (N = 1). Total length of genitalia: 0.6 mm.

Description.

Genitalia: In lateral view, segment IX semi-triangular with rounded apex located medially; in ventral view anteriorly widely U-shaped. Sternal processes, lateral view, with each apex barely exceeding posterior apex of tergum X, ventral margin almost straight, dorsal margin with rectangular protrusion after mid-length, apex acuminate; in ventral view, parallel, triangular with acuminate apices, rounded lobes after mid-length on lateral margin. Tergum X in lateral view pot-shaped with anterior margin concave, posterior margin straight, higher than long; in dorsal view, irregularly quadrilateral with slightly concave posterior margin. Parameres long, in lateral view slender equally wide along their length, curving upwards towards narrowly club-shaped apex with megasetae at ventral margin, ending before apex of superior appendage; in dorsal view, anterior half slender, converging, posterior half diverging, apex complex sheet-like folding, with megasetae on mesal surface. Superior appendages, in lateral view, triangular, twice as long as tergum X, apex with short spine; in dorsal view stout, longer than wide, slightly widening along their length, abruptly narrowing towards posteromesad directed spine-like apex. Inferior appendages, in lateral view, with posterad orientated large, lobe-like, blunt dorsal branch, ventral branch in the form of small tooth; in ventral view dorsal branch forming slender shape narrowing along its length, with slightly convex margins, two slender, converging posterior processes, ventral branch forming central tooth. Phallus, in lateral view slightly shorter than segment IX, carafe-shaped, straight; in ventral view tubular, straight.
