            <p> Opacoptera callirrhabda (Meyrick):  Gozmány , 1978: 179. </p>
            <p>Material examined.</p>
            <p> China: 1♀, 30.vii.2014 , 3♂, 2-3.viii.2014,   Yunnan, Dali,  Mt. Weibao , 2205 m, KJ Teng et al. leg., slide nos. YS19428  ♂, YS19435 ♀. </p>
            <p>Diagnosis.</p>
            <p> This species is diagnostic in the male genitalia by the juxta incised at middle in a triangle on the posterior margin (Fig. 11). It is similar to  O. condensata sp. nov., and the differences between them are stated in the diagnosis of the latter species. </p>
            <p>Description.</p>
            <p>Wingspan 13.5-15.0 mm (Fig. 3).</p>
            <p>Female genitalia (Fig. 18). Eighth abdominal sternite obtuse on posterior margin. Apophyses posteriores twice length of apophyses anteriores. Antrum cup-shaped, wrinkled, membranous except sclerotized along posterior margin forming a band. Ductus bursae subelliptical, slightly wider than corpus bursae, partly wrinkled anteriorly; ductus seminalis broad basally, slender distally. Corpus bursae elliptical; signa placed medially, consisting of five teeth in a longitudinal row and a small rounded, denticulate plate.</p>
            <p>Distribution.</p>
            <p> China (Sichuan, Yunnan) (  Gozmány 1978; Wu 1996). </p>
            <p>Remarks.</p>
            <p> Meyrick (1936) described this species based on five male specimens (one from Shandong, two from Shaanxi and Yunnan, respectively) and placed it in the genus  Lecithocera . Clarke (1965) assigned one of the specimens from Yunnan as the lectotype according to the original description.  Gozmány (1978) noted that only the two specimens from Yunnan were conspecific. He also hypothesized that they were distinct from  Lecithocera , so diagnosed the genus  Opacoptera and placed the species therein. Wu (1996) was first to described the female of  O. callirrhabda based on specimens with associated males collected at different times and from different localities of Sichuan. According to the description and the drawing given by Wu (1996), the female genitalia of  O. callirrhabda has a narrowed ductus bursae and a single signum. However, the female of the species examined in this study from Yunnan is quite different, and we describe it herein. </p>

            <p>Diagnosis.</p>
            <p> The male genitalia of the new species is similar to that of the type species,  O. callirrhabda (Meyrick, 1936). It can be distinguished by the forewing having two black patches, CuA1 stalked with CuA2, and ductus seminalis having dense granules; in  O. callirrhabda , the forewing has no black patches, CuA1 and CuA2 are separate, and the ductus seminalis has no granules. </p>
            <p>Description.</p>
            <p>Wingspan 13.0-15.0 mm (Fig. 4). Head dark brown. Antenna yellowish brown in basal 1/4, pale yellow in distal 3/4. Labial palpus yellowish brown, paler on inner surface; third palpomere as long as second palpomere. Thorax and tegula dark brown. Forewing dark brown, with two large, elliptical, black patches anteriorly reaching anterior margin of discal cell: first at basal 1/4, posteriorly reaching fold; second at middle, posteriorly reaching above dorsum; fringe dark brown; CuA1 and CuA2 short-stalked. Hindwing and fringe greyish brown; fringe with an orange white basal line.</p>
            <p>Male genitalia (Fig. 12). Uncus subcrescent. Gnathos with basal plate bell-shaped, bearing a papillary process at middle on posterior margin; median process wide in basal 1/3, narrowed to distal 2/5, thereafter slender to pointed apex, curved ventrad at distal 1/4 by a right angle. Valva wide in basal 1/4, narrowed slightly to cucullus; cucullus about half length of valva, narrowed slightly to obtusely oblique apex, costal margin shallowly concave except convex at base, ventrobasal process subtriangular, with a rounded apex; costal bar narrow, slightly expanded dorsad medially; sacculus a broad band, about 1/4 length of ventral margin of valva. Saccus rounded on anterior margin. Juxta broadly concave on posterior margin, denticulate along lateral sides of concavity; with a trapezoidal process at middle on anterior margin; posterior lobe strongly horn-shaped, curved outward at middle; posterolateral lobe short, narrow, extending laterally. Aedeagus nearly as long as valva, slightly widened medially, dorsal denticles larger than cornuti; cornuti consisting of 1-3 conic spines.</p>
            <p>Female genitalia (Fig. 19). Eighth abdominal sternite convex on posterior margin. Apophyses posteriores twice the length of apophyses anteriores. Antrum subrectangular, wrinkled, membranous except sclerotized along posterior margin forming a band. Ductus bursae narrowed posteriorly, widened distinctly toward corpus bursae, with diffused granules near base of ductus seminalis; ductus seminalis broad, with dense granules on inner wall. Corpus bursae large, elliptical; with two signa: one elliptical, with dense denticles, the other plate-shaped, bearing 3-6 teeth (Fig. 19a, b).</p>
            <p>Distribution.</p>
            <p>China (Chongqing, Henan, Hubei, Jiangxi, Shaanxi, Yunnan, Zhejiang).</p>
            <p>Etymology.</p>
            <p>The specific epithet is derived from the Latin condensatus, referring to the dense granules in the ductus seminalis.</p>

            <p>Diagnosis.</p>
            <p>This species can be distinguished from its congeners by the pale yellowish brown forewing, the juxta without posterior lobes in the male genitalia (Wu and Liu 1992: 681, fig. 2148), and the corpus bursae with a single signum in the female genitalia (Fig. 20).</p>

            <p>Remarks.</p>
            <p> Wu and Liu (1992) described the species from Hunan, China on a male and four females, and placed it in the genus  Opacoptera based mainly on the wing venation. But the species seems distinctive in the genus  Opacoptera both in appearance and genitalia as stated in the diagnosis. It probably does not belong to the present genus and the taxonomic status needs further study. </p>

Opacoptera 
Gozmany
, 1978
</p>
            <p> Opacoptera Gozmány , 1978. Type species:  Lecithocera callirrhabda Meyrick, 1936, by monotypy. </p>
            <p>Generic characters.</p>
            <p>Antenna as long as or slightly longer than forewing. Labial palpus with second palpomere thickened, third palpomere slender. Forewing narrowly elongate, usually dark brown with black patches; R1, R2 and R3 free, R4 and R5 stalked, M1, M2 and M3 separate, CuA1 and CuA2 short-stalked (Fig. 1) or separate (Fig. 2). Hindwing trapezoidal; M2 present, M3 and CuA1 coincident. All abdominal tergites with zones of spiniform setae.</p>
            <p>Male genitalia. Cucullus narrowed, usually with a ventrobasal process. Juxta with horn-shaped or needle-like posterior lobes extending dorsad and smaller posterolateral lobes extending laterally. Aedeagus with two dorsal denticles; cornuti spiniform or needle-like.</p>
            <p>Female genitalia. Antrum sclerotized along posterior margin forming a band. Signa of corpus bursae usually consisting of several teeth and a denticulate plate.</p>
            <p>Diagnosis.</p>
            <p> The genus is close to the monotypic genus,  Monerista Meyrick, 1925. It can be distinguished by the trapezoidal hindwing without streak; whereas in  Monerista , the lanceolate hindwing has a thinly scaled submedian streak (Clarke 1965: 183, fig. 1) </p>
            <p>Distribution.</p>
            <p> China (  Gozmány 1978; Wu and Liu 1992; Wu 1996), Thailand (Park and Kim 2021). </p>
            <p>Remarks.</p>
            <p> The generic characters of  Opacoptera were originally defined by  Gozmány (1978) based on the type species,  Opacoptera callirrhabda (Meyrick, 1936). Wu (1996) gave the female characters of the genus. In this paper, we revised the generic characters including the forewing venation, male and female genitalia after examining all species of the genus. </p>

            <p>Description.</p>
            <p>Wingspan 13.0-13.5 mm (Fig. 8). Head dark brown. Antenna with scape brownish yellow; flagellum orange yellow. Labial palpus orange yellow except dark brown ventrally on third palpomere; third palpomere as long as second palpomere. Thorax and tegula dark brown. Forewing dark brown, with two, narrow black patches, one at the basal 1/4 and one in the middle, distal 1/3 with diffused black scales; fringe dark brown; CuA1 and CuA2 short-stalked. Hindwing and fringe brown.</p>
            <p>Male genitalia (Fig. 15). Uncus subcrescent, broad V-shaped on posterior margin. Gnathos with median process slightly broad in basal 1/3, thereafter slendered to pointed apex, curved ventrad at distal 1/3 by a right angle. Valva wide in basal 1/4, narrowed distinctly to cucullus; cucullus about half length of valva, almost tubular, apex obtuse, costal margin shallowly concave, ventrobasal process thumbed; costal bar narrow, expanded dorsad medially; sacculus wide in basal half, slender in distal half, reaching cucullus. Saccus obtuse on anterior margin. Juxta subquadrate, broadly concave on posterior margin, densely denticulate along lateral sides of concavity; anterior margin obtusely produced at middle; posterior lobe large horn-shaped, longer than juxta, curved inward, triangularly produced at base on inner margin; posterolateral lobe small, spiniform. Aedeagus shorter than valva, slightly widened medially, with two tiny dorsal denticles; cornuti consisting of more than ten large, needle-like spines running from basal 1/4 to 3/4.</p>
            <p>Female genitalia (Fig. 22). Eighth abdominal sternite obtuse on posterior margin, with a sclerotized sac at anterolateral corner. Apophyses posteriores about twice length of apophyses anteriores. Antrum membranous except sclerotized along posterior margin forming a band, with two symmetrically sclerotized, leaf-like sclerites medially. Ductus bursae wrinkled, narrowed posteriorly, widened toward corpus bursae, with numerous conic spinules in anterior 3/5; ductus seminalis broad, arising from ductus bursae anteriorly, with sparse thorns on inner wall. Corpus bursae elliptical; signa consisting of several teeth of varied size in a longitudinal row placed posteriorly and a densely denticulate plate placed at middle.</p>

            <p>The new species can be distinguished from its congeners by the ventrobasally serrate cucullus and the apices of the posterior lobes of the juxta extending beyond the middle of the tegumen.</p>
            <p>Description.</p>
            <p>Wingspan 13.0-14.0 mm (Fig. 10). Head dark brown. Antenna orange yellow, paler distally. Labial palpus orange yellow except third palpomere dark brown ventrally; third palpomere as long as second palpomere. Thorax and tegula dark brown. Forewing dark brown, with diffused black scales distally; with two ill-defined black patches at basal 1/4 and middle respectively; fringe dark brown; CuA1 and CuA2 short-stalked. Hindwing and fringe brown; fringe with an orange white basal line.</p>
            <p>Male genitalia (Fig. 17). Uncus subrectangular, semicircularly concave on posterior margin; caudal lobe seimiovate. Gnathos with median process wide at base, narrowed to middle, slendered from middle to pointed apex, curved ventrad at distal 1/4 by a right angle. Valva wide at base, narrowed slightly to cucullus; cucullus about half length of valva, narrowed to obtusely rounded apex, costal margin expanded dorsad basally, ventral margin serrate ventrobasally and gently concave at middle; costal bar narrow, slightly arched, triangularly produced at middle on dorsal margin; sacculus narrow basally, widened distally, about 1/4 length of ventral margin of valva. Saccus rounded on anterior margin. Juxta deeply concave in V-shape on posterior margin, with a papillary process at middle on anterior margin; posterior lobe large horn-shaped, extending beyond middle of tegumen apically; posterolateral lobe small, narrowly banded, extending posterolaterally. Aedeagus nearly as long as valva, slightly widened medially, with two dorsal denticles; cornuti consisting of three large needle-like spines.</p>
            <p>Female unknown.</p>
            <p>Distribution.</p>
            <p>China (Yunnan).</p>
            <p>Etymology.</p>
            <p>The specific name is derived from the Latin longissimus, referring to the long posterior lobe of the juxta.</p>
