Behounek and W. Speidel.

Diagnosis. Externally L. diehli differs from its allies by smaller size, much longer labial palpi, more contrasting and darker wing pattern, clearly expressed white bars on ante- and postmedial lines and bright orange, brown bordered patch between white bars in dorsal part of forewing. Male genitalia with peculiar structure, basically similar to L. takao , but with strongly sclerotised costa with dentate dorsal margin, apically separated from membranous valva, relatively short clasper with small harpe and strong, curved apical extension of sacculus.

Description. Adult ( Figs. 5, 6 ). Wingspan of male, 20.5– 23 mm, of female 24–25 mm. Labial palpi longer than in other species of the genus, narrow, flattened ventrally, with long 2nd segment and pointed 3rd segment, which is 3 times shorter than 2nd. Abdomen with tuft of black scales on segments 1–3. Ground color of forewing bright purplish-brown with some magenta tint from base to antemedian line and darker magentabrown in outer part of wing; basal line not expressed, basal and subbasal fields in costal area magenta brown, darker than ground color; antemedial line thin, orange in dorsal part with distinct white bar in dorsal part of wing, blackish in medial part of wing, weakly traceable and widely diffused in costal part, acutely angular basally; postmedial line arises on dorsum as pure white, oblique, contrasting bar, narrowing to thin hardly traceable blackish line beyond Cu1 bordered white near costa, angled basally towards costa, running parallel to antemedial line, and bordered inside by diffused dark magenta-brown suffusion; area between white bars of ante- and postmedial lines filled with orange, bordered with brown; orbicular not expressed, reniform reduced to small twin blackish comma-like dot with black diffused streak to apical angle of subterminal line; area between black streak and costal margin magenta-brown; subterminal line thin, waved, whitish; subterminal field magenta-brown, with wide black-brown suffusion along subterminal line, with pale ash-grey suffusion and 2 to 3 black semilunar spots with white border in costal area; terminal field magenta-brown, darker in costal part, with clear orange apical mark bordered with brown; terminal line whitish, thin; cilia brown. Hindwing greyish-brown, darker in outer area; cilia yellowish-grey. Male genitalia ( Fig. 27 ). Uncus thin, sickle-like; tegumen higher than vinculum, weakly sclerotised; juxta three-lobed, with wide lateral lobes and small medial lobe; valva moderately long, slightly constricted medially; transtilla well expressed, band-like; costa well developed, sclerotized with serrated edges at dortral margin, in apical part separated from membranous valva; clasper and harpe lie in longitudinal position, along costa, clasper with elongate sclerotized basal plate, harpe very small; sacculus very small, well formed, with large flattened, curved extension, slightly longer than half of valva; apical part of valva membranous, rounded, lobe-like; aedeagus relatively thin, moderate, with moderate coecum, vesica bulbous, with finely scobinated row of cornuti. Female genitalia ( Fig. 42 ). Similar to L. flaviplaga : ovipositor short, papillae anales quadrangular, apophyses short, anterior apophyses 1.5 times shorter than posterior ones; antrum wide, cup-like in shape, with deep triangular incision in ostial margin; ductus bursae wide and relatively short, sclerotized, with rounded lateral extensions in mid part; corpus bursae rounded, rather wide, with single wide singnum above mid of bursa.

Distribution and biology. ( Fig. 61 ). Indonesia, Sumatra. The type series was collected in a mountainous region at an elevation of 1050–1150 m. Adults were taken from February to December. The species is multivoltine; larvae and foodplants are unknown.

Etymology. The species is dedicated to late E. D.W. Diehl who explored the fauna of Sumatra.
