Temnolopha matura Diakonoff, 1973, Zool. Monogr. Rijksmus. Nat. Hist. 1: 322. Type locality: Indonesia (East Borneo, Tabang, Bengen River). Holotype (Ƥ): RMNH.
Diagnosis. The wing pattern of Temnolopha matura is similar to that of T. mosaica but the former has pale sinuate striae distinctly edged with ochreous. The male hind tibia has a well-developed black hair pencil, which is present in T. abstursana but absent in all other known Temnolopha species. The male genitalia are very similar to those of T. abstrusana with the uncus gradually tapering; the valvae asymmetrical with a tooth on the edge of the basal excavation and a row of strong, blunt spines from the base of the costa; and a long, slender, tapering aedeagus with a dorsal process near the apex. T. matura differs from T. abstrusana by the presence of two distinct, long spines near the basal excavation on the right valve and by a bend in the aedeagus 1/3 from base rather than in the middle. The female genitalia have a subelliptical, complex sterigma fused with a long colliculum and a single signum comprised of a patch of scobination with usually a single, flattened tooth-shaped central sclerite.
Description. Head: Upper frons pale brown, lower frons with very short, appressed scales, pale grey; labial palpus moderately long, pointed and sinuate, first segment small and short, greyish white, second segment sinuate and distally widened, yellowish grey with two distinct narrow band, dark brown, one extending from near dorsomedially to apicoventrally, the other extending obliquely from dorsobasally to apicoventrally, dorsoapically pale brown, apical segment moderately long, yellowish grey; vertex pale brown to brown. Thorax: Pronotal collar brown; tegulae greyish white on basal third, rest brownish grey; mesonotum light brown to brownish grey with posterior margin greyish white; posterior scale tuft present, brown. Forewing length 8.2 mm in male (n=1) (Fig. 1), 8.6–8.8 mm in female (n=2) (Fig.2); elongate subrectangular, costa lightly curved, male costal fold absent; termen straight; ground color greyish brown to light brown; costal strigulae 1 and 2 indistinct, strigulae 3–9 paired and separated by small dark brown spots; one-third of wing length basally forming irregular basal patch, present as a narrow longitudinal strip between Sc and R, dark brown, with the other large oblique patch, wedge-shaped, extending from inner margin basally to discal cell medially, dark brown; median patch also interrupted and irregular, extending from costa between strigulae 4 and 7 to inner margin, present as oblique tusk-shaped mark on costa, point curved upwardly, dark brown, its upper edge parallel to lower edge of tusk, brown to dark brown; preterminal mark light brown, extending from inner margin to M3 together with distal striae; apical third of wing with large crescent-shaped mark, brown to dark brown, extending from R5 to between CuA1 and CuA2. Underside pale brown to brown distally becoming paler basally; anal margin with distinct small anal lobe covered with dense scales in male. Hindwing brown with underside pale brown. Hind tibia thickened, modified in male, with a pencil of long, dense, black hair scales along basal third of tibia (Fig. 3). Abdomen: Pregenital abdomen in both sexes with two deep round dorsal depressions laterally toward base of tergum II. Male genitalia (Fig. 4) with tegumen roughly triangular, outer margin slightly concave in apical third, with distinct shoulders, sparsely setose; uncus subtriangular, rounded at apex, sparsely setose in basal third, below apex with dense patch of spines; socii drooping, membranous lobes, moderately long and rounded apically, covered with dense long thin hairs; gnathos a weakly sclerotized narrow band, arising from dorsal one-third of tegumen; anellus closely surrounding basal fifth of aedeagus; phallus long, slightly tapering to apex, dorsal margin angled one-third from base, with small sclerotized subtriangular lobe dorsoapically; valvae large and wide, asymmetrical, right valva wider in basal half with outer margin not concave and forming neck as in left one; sacculus with moderately dense long setae basally and on ventral edge with group of dense scales, right sacculus with group of very long curved bristles from outer surface which is absent on left valva, distal margin of basal excavation with sharply pointed triangular process, right valva in addition with two long spines near ventral margin of basal opening; cucullus wide, tapering to rounded at apex, covered with dense short spines and setae, right cucullus more narrowed towards apex and with a transverse row of dense bristles at base, left cucullus demarcated by a neck on ventral margin and with a more pronounced subapical notch; base of costa with a row of very thick, blunt spines, with a cluster of outwardly directed thinner spines beneath on right valva. Female genitalia (Fig. 5–7) with sternum VI posteriorly sclerotized, sternum VII sclerotized and posteriorly narrowed, posterior margin with a Vshaped excavation; tergum VII sclerotized with posterior margin slightly concave, tergum VIII with moderately dense short hairlike setae on triangular lateral extensions; papillae anales densely setose, lateral setae with papillose bases; sterigma (Fig. 6) vertically subelliptical, strongly sclerotized with dense microtrichia, rising above edge of sternum VII, with membrane laterally to sterigma lightly sclerotized with short and dense microtrichia near sterigma; lamella antevaginalis large, knoblike, lamella postvaginalis large, rooflike consisting of two pieces connected apically, swollen lateroventrally; colliculum strongly sclerotized, half as long as ductus bursa and fused with sterigma; ductus seminalis arising from near midlength of tegumen; corpus bursa ovate, with one signum (Fig. 7) consisting of a patch of scobination with usually one large central tooth, flattened, subrectangular, surrounded by small and erect sclerites.
