Type species.
Hoploscopa astrapias Meyrick, 1886, by monotypy.
Diagnosis.
Hoploscopa displays brown to dark brown forewings, often bearing pale yellow-, yellow-, or red-coloured median and postmedian diagonal stripes. In male genitalia, the uncus is well developed, the gnathos forms a ribbon-like structure, often with a posterior projection, and the vinculum bears laterally a pair of coremata. In female genitalia, the antrum is short, often sclerotised, and the corpus bursae bears a thorn, often with a basal sclerotisation. Hoploscopa is morphologically very similar to Perimeceta . The forewings of Perimeceta are slightly larger, display a yellow to brown ground colour, with one basal elliptic and one postmedian lunule-shaped white spot. In male genitalia, Perimeceta shows a spade-shaped uncus, the gnathos arms connect shortly after arising and are expanded posteriorly into an elongated tip, the valva shows a conspicuously rounded ventral margin, and is apically narrowed into a tip, while the ventral margin is more or less straight in Hoploscopa . Perimeceta exhibits female genitalia similar to those of Hoploscopa with a slender ductus bursae and a rounded corpus bursa bearing a thorn. However, the latter displays a membranous antrum in female genitalia, while it is sclerotised in most species of Hoploscopa .

Maxillary palpi brown to dark brown, first segment pale yellow, inner side brown to pale yellow. Labial palpi porrect, 2-2.9 × diameter of compound eye, brown, white to pale yellow at base, inner side brown to pale yellow.
Thorax (Figs 1 View Figures 1–3 - 45 View Figures 34–45 ). Collar white to pale yellow. Frenulum simple in ♂, triple in ♀. Forewing length 7-13 mm, 2.4-2.9 × maximal width, females slightly larger than males. Wing venation (Fig. 2 View Figures 1–3 ): R1 not connected to Sc; R2, R3 and R4 stalked together; R5 free, arising from upper corner of cell; M1, M2 not stalked; M3 arising from lower corner of cell; CuA1 arising below lower corner; CuA2 at distal 1/3 of cell; 1A+2A arising from cell base; Hindwing Sc+R1 connected to Rs at distal 1/3; M1 connected to Sc+R1 by short vein; cell closed; M2, M3 and CuA1 arising at lower angle of cell; CuA2 arising at middle of cell; 1A, 2A, 3A free. Forewing ground colour brown to dark brown, markings white, yellow or red colour. The pattern elements can be described as follows (Fig. 3 View Figures 1–3 ):
cf costal field stretched along costa up to postmedian area;
bs basal streak small, weakly or not marked;
bp basal patch often quadrangular, ill-defined;
pds and dds proximal and distal discoidal stigmata along costal field;
mds the median discoidal stigma trapezoid, with costal edge longer than dorsal one;
mcp and mdp median cubital patch and median dorsal patch in line with median discoidal stigma, often forming together a Y-shape pattern;
pmp postmedian patch roughly triangular, narrowing at costa;
pml postmedian line running from costa to middle of dorsum, often barely marked, mostly visible close to costa;
pma postmedian area often suffused to a various extend with white, yellow or red;
sbl subterminal line running from costa close to apex towards dorsum, often incurved inwards at CuA2;
sbf subterminal field more or less suffused with brown, red or yellow.
The margin is brown, in some species with spots, fringe unicoloured or chequered.
Hindwing upper side pale yellow to pale brown; underside pale yellow, with brown markings on costa and subterminal line toward costa; males of some species with androconial organ on the upper side at dorsum, consisting of upright scales along CuA2 and 1A veins and a protruded margin between CuA2 and 1A, bearing a patch of greyish scales. Forelegs brown to dark brown. Midlegs with femur brown, tibia and tarsi often pale yellow, speckled with brown. Hindlegs pale yellow on inner side, pale yellow to brown on outer side, tarsi bronze to pale brown.

Distribution.
Hoploscopa is found from the Malay Peninsula and Sumatra in the West to the Samoa Islands in the East, as well as from the North of Thailand to Vanuatu and Fiji in the South. It is absent from Queensland (Australia) and New Caledonia. It is predominantly found in tropical mountain forests, with only few species encountered in the lowlands.
Biology.
Host plant data is available for five Hoploscopa species, all feeding on ferns. The larvae of H. gombongi sp. nov., H. obliqua and H. tonsepi sp. nov. from Papua New Guinea are reported from Diplazium esculentum (Retzius in Retzius & König, 1791) Swartz, 1803 ( Athyriaceae ) ( Miller et al. 2015, Mally et al. 2017). Another undescribed Hoploscopa species (sample USNM_ENT_00739239) from Papua New Guinea is reported from Sphaerostephanos unitus (Linnaeus, 1759) Holttum, 1794 ( Thelypteridaceae ) (ibid). Lastly, one undescribed Hoploscopa species from Borneo is reported from the fern Dicranopteris linearis (Burman, 1768) Underwood, 1907 ( Gleicheniaceae ) ( Mally et al. 2017).
