Material examined.
Holotype: ♀, with labels: "Papua New Guinea: W[estern]. H[ig]hl[and] | Pr[o]v[ince], n[ea]r Mt. Hagen, Kuk Ag | Res[earch].

Paratypes: 1 ♂, 1 ♀. Papua New Guinea: 1 ♂, 1 ♀ (♂ with DNA voucher MTD LEP3161 & genitalia on slide TL441 ♂; ♀ with DNA voucher MTD LEP3155 & genitalia on slide TL435 ♀), same data as holotype (USNM).
Diagnosis.
The forewings of H. pseudometacrossa sp. nov. display barely marked median discoidal stigma and postmedian patch, while basal and distal discoidal patches are dark brown. Male hindwing displays an androconial organ on the dorsum. In male genitalia, the gnathos shows a short, thumb-like projection, and the juxta is slender, with notched apex. In female genitalia, the ductus bursae is relatively short-sized, the corpus bursae is large, spherical, with a small straight thorn.
Similar species.
Hoploscopa boleta sp. nov. (q.v.), H. metacrossa , H. kelama sp. nov. (q.v.). Forewing median discoidal stigma forms a pale yellow Y with median cubital patch in H. metacrossa . In male genitalia, gnathos projection of H. metacrossa is thinner, valva is larger, and juxta apex is rounded. Female genitalia are very similar, but the antrum sclerotisation is shorter, and the corpus bursae smaller in H. metacrossa .
Description.
Head. Antennae dorsally with bronze to brown scales. Proboscis pale yellow to brown. Maxillary palpi brown, base and inner side pale yellow. Labial palpi brown, ventro-basally pale yellow.
Thorax (Fig. 41 View Figures 34–45 ). Collar pale yellow. Forewing length: 9-10 mm (♂ & ♀); forewing ground colour brown; basal dash dark brown, distally pale yellow; basal and distal discoidal stigma quadrangular, dark brown; median discoidal stigma faded, basally and distally thinly edged with pale yellow; postmedian patch faded, with distal edge dark brown, at costa with pale yellow blotch; postmedian line marked on costal half; postmedian area suffused with pale yellow near costa; subterminal line pale yellow; fringe brown, with pale yellow dots. Hindwing pale brown; in males, presence of an androconial organ on the dorsum of the hindwing. Forelegs brown. Mid- and hindlegs with femur brown, tibia brown speckled with pale yellow, tarsi bronze.
Abdomen. Male sternum A8 posterior margin broadly indented, with short, rounded lateral projections.
Male genitalia (N = 1) (Fig. 80 View Figures 76–81 ). Uncus slender, narrowed on apical 1/4 which bears thick setae, apex missing on slide examinated. Gnathos projection thumb-shaped, ca. 1/4 of uncus length. Valva ventral margin bent dorsad on distal half, dorsal margin medially angled, apex roughly rounded. Juxta with base rounded, medially narrowed, apex notched. Saccus broad, triangular, pointing dorsad.
Female genitalia (N = 2) (Fig. 120 View Figures 119–122 ). Anterior apophyses with dorsal bump at posterior 1/3. Antrum sclerotisation twice as long as broad. Ductus bursae short, more or less straight, bent before corpus opening. Corpus bursae large, posterior half reticulated, medially covered with erect acanthae, anterior half membranous, with weak sclerotisation at thorn base. Thorn straight, with small dents pointing toward thorn base, basally with small outwardly projected extension.
Distribution.
Known from Mount Hagen in the Morobe Province (Papua New Guinea), at an altitude of 1,600 m.
Phylogenetic relationships.
The hindwing scent scales observed in males of H. jubata sp. nov., H. pseudometacrossa sp. nov., and H. metacrossa suggest a close relationship between these three species.
Etymology.
The name is made by the apposition of the prefix pseudo - from the Greek pseudes, false and metacrossa , referring to the resemblance of this species with H. metacrossa .
