Diagnosis.

Males of this species are readily recognised by the band of elongate-ovoid black scales that stretches almost the length of the forewing; in features of genitalia they closely resemble Caledonotrichia minor and Caledonotrichia vexilla sp. n. Females not associated.

Description, male.

Head rounded (Fig. 1). Antennae with 24 flagellomeres; flagellomeres elongate cylindrical, longest with length about 3 × width. Maxillary palps with basal 2 segments short and rounded, rest cylindrical: segment 3 about 4 × maximum width, segment 4 length about 2.5 × width, segment 5 elongate slender, length almost 6 × width.

Wings. Forewing (Fig. 8) length, 1.0-1.7 mm (n=5); bearing elongate patch of black scales (androconia) medially reaching almost from leading proximal angle to about two-thirds wing length, and separate small patch close to proximal margin; costal margin hairs straight. Hind wing bearing small rather scattered black scales, more slender than those of forewing.

Genitalia (Figs 51-53, 64-65). Abdominal segment IX rounded proximally, apical margin cleft medially. Tergite X with lateral margins slightly rounded, apically concave. Gonopods with ventral lobes triangular, apical margin slightly concave, dorsal lobes elongate rectangular; axillary seta not apparent. Sclerotised rods of subgenital process in ventral view with small cap-like irregularity apically and another subapically, in lateral view dilated apically. Phallic apparatus elongate, slender, strongly curved at about two-thirds length, with stout parameres.

Material examined.

Holotype male: New Caledonia: Rivière du Cap, Pont du Cap, ~8 km NW Naindai on Bourail-Poya road, 22.xii.1998, A. Wells (MNHP).

Paratypes: 5 males, same data as for holotype (one on slide) (ANIC).

Etymology.

Remarks.

The specimens of this species were collected as they ran about in sunlight on the surfaces of emergent rocks in the stream.
