Material examined.
Lectotype: ♀, with labels: "Lecto- | type" [round label, purple ringed]; “Vunîdawa | Fiji | HP. 2. 1. [19]32" [handwritten]; "HOPLOSCOPA Meyr." [handwritten]; "astrapias Meyr." [handwritten]; "Hoploscopa | astrapias | 1/1 Meyrick [handwritten] | E. Meyrick det. | in Meyrick Coll."; "Lectotype | Hoploscopa | astrapias | Meyrick | det. M. Nuß” [handwritten]; "Meyrick Coll. | B. M. 1938-290."; "♀ | Pyralidae | Brit[ish].Mus[eum]. | Slide N°. | 20241"; "GU 654 | Hoploscopa | astrapias | Matthias Nuß”; " NHMUK 010923383" [barcode appended]. Deposited in NHMUK.
Other specimens examined.
1 ♂, 1 ♀. Fiji: 1 ♂ (DNA voucher MTD8251, genitalia on slide TL724 ♂), 1 ♀ (DNA voucher MTD8250, genitalia on slide TL723 ♀), Viti Levu, Nandarivatu, 820 m, 14.9.1955, leg. H. W. Simmonds (NHMUK).
Diagnosis.
The forewings of H. astrapias display a median cubital triangular white patch and a bean-shaped postmedian patch red with yellow edges, distally with thick white streak. In male genitalia, the uncus is slender, elongated, the gnathos is reduced to a ring without posterior projection and the valva is slender, with an evenly rounded apex. In female genitalia, the corpus bursae is large, spherical, and bears a large, straight, glabrous thorn.
Similar species.
Hoploscopa anamesa , H. nauticorum but the latter can be separated from H. astrapias and H. anamesa based on the forewing: median markings form an elongated white streak running down to dorsal area, disrupted at veins (forming roughly triangular white patch not extending beyond CuA2 in the two other species), and the postmedian patch is quadrangular. In male genitalia, the bristles at uncus apex observed in H. nauticorum are absent or reduced in H. astrapias and H. anamesa , and the valva dorsal margin is strongly produced dorsad on basal half, with a more pointed apex in H. nauticorum (dorsal margin slightly convex in two other species, apex evenly rounded). Forewing and male genitalia of H. astrapias and H. anamesa do not provide unambiguous diagnostic characters to separate them. Median cubital patch of H. anamesa is slightly thicker than that of H. astrapias in specimens examined. Female genitalia allow clear segregation of these two species: antrum is membranous in H. anamesa , while it is lightly sclerotised, twice as long as broad in H. astrapias , and ductus bursae is long, gently coiled twice in H. anamesa , while it is short and broadly curved in H. astrapias .
Description.
Head. Antennae dorsally with brown scales. Proboscis white to pale yellow. Maxillary palpi brown, base and inner side pale brown. Labial palpi brown, ventro-basally pale yellow to white.
Thorax (Fig. 27 View Figures 19–33 ). Collar white. Forewing length: 10-11 mm (♂ & ♀); forewing ground colour brown; basal yellow streak along 1A+2A, abutted with cubital reddish brown fascia running up to median area, disrupted by median cubital patch; costal field reddish brown; median discoidal stigma trapezoid, reddish brown, edged basally and distally with yellow, median cubital patch triangular, snow white, together with median discoidal stigma forming a canine tooth shape; post-median patch bean-shaped, reddish brown with yellow edges, with thick snow white streak abutting dorsally; postmedian area suffused with reddish brown; subterminal line white, not reaching dorsum; subterminal field broadly marked with reddish brown; fringes brown. Hindwing pale yellow, bronze toward distal margin. Forelegs brown. Midlegs brown to bronze; tibia medially white. Hindlegs brown to bronze, tibia base dorsally pale yellow.
Male genitalia (N = 1) (Fig. 68 View Figures 64–69 ). Uncus long, slender, with straight lateral margin, apex narrow, tongue-shaped, dorsally with sclerotised bristles. Gnathos projection limited to small ridge. Valva slender, ventral margin nearly straight, dorsal margin slightly convex, apex rounded. Juxta broad, with base rounded, apex weakly sclerotised, slightly incurved. Saccus small, pointing dorsad. Phallus with large flat spatula-shaped cornutus.
Female genitalia (N = 1) (Fig. 107 View Figures 107–110 ). Anterior apophyses with dorsal bump at posterior 1/3. Antrum lightly sclerotised, twice as long as broad. Ductus bursae of medium length, broadly curved. Corpus bursae globular, with posterior half reticulated, anterior half membranous, with weak sclerotisation between thorn and corpus opening. Thorn long and slender, straight, glabrous.
Distribution.
Known from the island of Viti Levu (Fiji), at altitudes between 0 and 800 m.
DNA barcoding.
Hoploscopa astrapias shows a divergence of 3.9% with H. anamesa and 3.3-4.7% with H. nauticorum .
Phylogenetic relationships.
Hoploscopa astrapias , H. anamesa , and H. nauticorum are recovered together in the ML analysis of the COI barcode (BS = 61). This topology is congruent with the morphology of these three species: the forewings display a snow white transversal median line and postmedian streak; in male genitalia, the uncus is elongated, slender, the gnathos is reduced to a sclerotised band without posterior projection, the phallus bears a large, flattened, spatula-shaped cornutus; in female genitalia, the corpus bursae is globular and bears a long and slender straight thorn. Within this clade, a close relationship between H. astrapias and H. anamesa is supported by both morphology and molecular data (BS = 78).
