Diagnosis. Xenolepis cultrata sp. nov. is superficially similar to Xenolepis apicula sp. nov., but the male genitalia of X. cultrata sp. nov. are distinguished from all other congeners by a rather straight cucullus.

Description. Head ( Fig. 6 View FIGURES 1–6 ): Lower frons orangish white to pale orange, upper frons light orange; vertex dark brown iridescent in angled light, with light orange scales basally, antenna dark brown with orange antennal base; antenna dark brown, except light orange at base; labial palpi porrect, first segment short, white mixed with brown, second segment upcurved, rather parallel sided, light orangish with white scale along ventral margin and a narrow greyish brown strip dorsomedially, apical segment narrow and rather short, light orange.

Thorax: Pronotal collar dark brown iridescent in angled light; mesonotum dark brown with two orange marks anterolaterally, with a transverse wide curved orange band medially, posterior end with a small orange mark; tegulae dark brown with a large orange patch over basal 1/2 of length. Forewing subrectangular, wingspan 10.3–10.5 mm in males ( Fig. 5 View FIGURES 1–6 ) (n = 2); costal margin evenly curved; rounded apex; termen rather straight from R 5 to CuA 1, then oblique to tornus; basal 1/2 of costal margin with four dark brown spots, costal strigulae well developed in apical 1/2 of costa, orangish white, separated by small dark brown streaks; ground color orange; basal patch reticulated, dark brown, extending from wing base to near middle of wing and from Sc to dorsum; median patch wide, dark brown, irregular, broken by ground color, extending from costa to dorsum, anterior margin sinuate, extending from middle of costa curve to median of dorsum, posterior margin extending obliquely outward from beyond middle of costa to M 1, then downward to dorsum near tornus; tornus with a very small dark brown spot; ocelloid area with two moderately large silvery roundish marks between M 2 to between CuA 2 and 1A+2A, and a very small silvery spot above tornal mark; terminal patch an irregular oblique band, light brown mixed with dark brown, extending from near costa at R 2 to termen between M 1 and CuA 1, ventromedially with a transverse narrow band extending downward to M 3, apical 1/2 of costa with oblique silvery striae; fringe scales orange alternated with dark brown; underside dark greyish brown with trace of upper side ground color marks, with whitish spots along costa; termen with a narrow whitish line from wing apex to between M 3 and CuA 1, and whitish marks between R 5 and M 2. Hindwing subtriangular, outer margin slightly curved, brown, slightly paler to wing base, especially in anal area between 1A+2A and anal margin; anal margin with a sclerotized ridge, folded upward forming a groove with a tuft of long whitish scales (= hair pencil) ( Fig. 9 View FIGURES 8–9 ); fringe scales brown except whitish anal angle; underside light brown slightly paler to base.

Abdomen ( Fig. 13 View FIGURES 11–13 ): Sternum VIII with a large weakly sclerotized plate, posterior margin deeply concaved medially, broadly V-shaped, lateral margin rather straight, abruptly narrowed to a very slender line anteromedially extending to anterior margin, with dense scale sockets along posterior margin, denser at posterolateral corners, with a narrow, small patch of very dense scale sockets at lateral margin near posterolateral corners. Male genitalia ( Figs. 16 View FIGURES 14–16 , 19 View FIGURES 17–19 , 22 View FIGURES 20–22 ) with tegumen subrectangular, rather narrow with dense scale sockets lateromedially; uncus broad, subtriangular, bilobed with rounded apices, moderately dense scale sockets; socii small, membranous, lobe-like, covered with sparsely dense setae and microtrichia; gnathos arising from apical 1/4 of tegumen, a rather narrow, sclerotized band, broader medially, concaved lateromedially and enlarged to broad rounded apex projecting upward to near apex of uncus; vinculum moderately wide; juxta subrectangular; caulis short; anellus wide, cup-shaped surrounding basal 1/3 of phallus; phallus cylindrical, moderately long, wide, curved medially; valva elongate, rather narrow and straight, slightly tapered to narrow rounded apex; sacculus short, about 1/4 length of valva, with a group of moderately dense, short setae basally, beyond with a dense group of short setae at ventroapical margin, with a small group of moderately dense scale sockets medially near basal opening; cucullus elongate-subtriangular, slightly narrowed to rounded apex, dorsal margin rather straight, ventral margin slightly curved, posterior surface densely covered with distinct spines, strongly bent, with enlarged bifid apices, except along dorsal margin to apex covered with sparse setae, denser apically, with a group of dense short stout spines ventrobasally.

Distribution. Thailand (Chantaburi and Trat province).

Etymology. The specific epithet (cultratus = knife-shaped) refers to the shape of the valva.
