Treatment

Acritoptila macrospina sp. n. Figs 21-23, 35

Diagnosis.

The males of this species differ from all other New Caledonian species in having among genitalic structures stout, sclerotized asymmetrical parameres, in ventral view sharply angled mesally.

Description, male.

Antennae each with 26-31 flagellomeres, with large sensilla placodea on surfaces; forewing length 1.9-2.0 mm (n = 5).

Male genitalia (Figs 21-23). Abdominal segment VII bearing a slender elongate process mid-ventrally. Abdominal segment VIII shorter than IX. Abdominal segment IX in lateral view broader than long, in ventral view widely excavated apico-mesally. Gonopods in ventral view in form of discrete triangular lobes, each with a small rounded knob-like seta at about 2/3 length. Subgenital processes irregular in shape, in ventral view forming rounded lobe medially and pair of apically acute lobes laterally. Parameres leaf-shaped, left longer than right, in lateral view sharply down-turned, in ventral view directed mesad. Phallic apparatus elongate, dilated subapically with a slender re-curved apical spine. Female: unknown.
