Other specimens examined.
2 ♂. Samoa: 2 ♂ (DNA vouchers MTD8252 & MTD8253, genitalia on slide TL725 ♂ & TL726 ♂), West Samoa, Upolu, Tiavi, 600 m, 24.viii.1974, leg. G. S. Robinson (NHMUK).
Diagnosis.
The forewings of H. nauticorum display snow white median, cubital and dorsal markings together forming a streak disrupted with brown at veins, and a postmedian triangular red patch, distally with snow white streak. In male genitalia, the small sclerotised bristles on dorsal side of the uncus apex are unique to this species. Female genitalia were not investigated.
Similar species.
Hoploscopa astrapias (q.v.), H. anamesa (see H. astrapias ).
Description.
Head. Antennae dorsally bronze. Proboscis brown, speckled with pale yellow. Maxillary palpi dark brown, basally pale yellow, inner side brown. Labial palpi dark brown, ventral base pale yellow.
Thorax (Fig. 29 View Figures 19–33 ). Collar pale brown. Forewing length: 10-11 mm; forewing ground colour dark brown; basal yellow streak along 1A + 2A, abutted to cubital red fascia running up to postmedian area, disrupted by median cubital patch; small reddish blotch at base of cell, with minute snow white dot; median discoidal stigma trapezoid, red, basally and distally edged with yellow, with snow white streak abutting dorsally, running down to dorsal area, disrupted at veins; postmedian patch quadrangular, red, dorso-distally with thick snow white streak; subterminal line white, indented inwardly at CuA2; subterminal field red; fringe brown. Hindwing pale yellow, bronze toward distal margin. Forelegs brown, tarsi speckled with pale yellow. Midlegs brown; tibia base speckled with pale yellow. Hindlegs brown.
Abdomen. Male sternum A8 posterior margin broadly indented, with short, rounded lateral projections.
Male genitalia (N = 3) (Fig. 70 View Figures 70–75 ). Uncus long and slender, gently tapering toward apex, apex narrow, tongue-shaped, dorsally with few small sclerotised bristles. Gnathos without posterior projection. Valva ventral margin nearly straight, dorsal margin strongly protruding dorsad on basal half, apex rounded. Saccus broad, medially slightly incurved. Phallus with large, flat, spatula-shaped cornutus.
Female genitalia. Not investigated.
Distribution.
Known from the island of Upolu on Samoa, at an altitude of ca. 600 m.
Phylogenetic relationships.
Hoploscopa nauticorum is recovered as sister to H. astrapias and H. anamesa in the ML analysis of the COI barcode (BS = 61). See H. astrapias for further remarks.
