Diagnosis. Commoneria sinuata sp. nov. is distinguished from other species in the genus by its strongly sinuate outer margin of the male hindwing; a tuft of moderately short, narrow, pointed scales on each side of tergum VIII laterally; a large curved, sclerotized process beyond the apex of the tegumen; a large patch of long modified scales on the valva dorsobasally; and a long, slender phallus parallel-sided in the apical 3/ 4 in male genitalia; and female genitalia with a narrow, moderately long ductus bursae, and two moderately large thorn-like signa.

Description. Head (Figs. 5–6): Lower frons yellowish white, upper frons yellowish to light brown; vertex brown, iridescent in angled light; labial palpi porrect, first segment yellowish white, second segment curved upward with margins rather parallel, slightly widened medially, yellowish, slightly darker to apex, apical segment narrow and rather short, yellowish; antenna brown, reaching to middle of forewing.

Thorax: Pronotal collar, mesonotum and tegulae brown, iridescent in angled light; without posterior crest. Forewing subrectangular, wingspan 13.0 mm in male (Fig. 1) (n = 1), 11.7 mm in female (Fig. 2) (n = 1); costal margin evenly curved; termen with a deep notch below rounded apex between R 5 and M 1, followed by a moderately large lobe of termen, rounded apex exceeding wing apex; costal strigulae indistinct on apical half, except for a pair of distinctly large white strigulae near apex, extending to between R 4 and R 5, separated by brown streaks; ground color light brown to brown with diffuse irregular transverse striae, brownish grey, iridescent in angled light; median fascia rather narrow, short, extending obliquely from costa to R 4, dark brown; postmedian fascia narrow and sinuate, extending obliquely from costa to termen at M 2, dark brown; two oblique leaden lines, first between median and postmedian fascia extending obliquely from costa to R 4, second beyond postmedian fascia extending obliquely from costa to near termen between R 4 and R 5; a row of three blackish spots near termen between M 2 and CuA 2; fringe scales with inner row dark brown, outer row light brown; underside greyish brown with indistinct greyish white spots along apical half of costa, with trace of a pair of strigulae 9 near apex, with a row of indistinct dark brown spots between M 2 and CuA 2. Hindwing subrectangular, brown, slightly paler to base; with strongly sinuate outer margin in male, fringe scales with inner row dark brown, outer row light brown; underside light brown, slightly paler to base; female with 3 spines in frenulum.

Abdomen: Pregenital abdomen in male (Fig. 13) with sternum II bearing large anterolateral process; sternum VIII with a patch of dense scale sockets posterolaterally; tergum VIII with a patch of dense, moderately long, narrow, pointed setae posterolaterally, connected with a very narrow, sclerotized, sinuate line, fused medially forming a narrow, sclerotized, straight line pointing inwardly. Male genitalia (Fig. 15) with tegumen subtriangular, basal 2/3 narrow, apical 1/3 wider, apex connected with a large curved process, rounded apex protruding upward, moderately sclerotized; uncus and socii absent; gnathos a moderately wide transverse band, weakly sclerotized; vinculum a narrow sclerotized band; juxta subtriangular; caulis moderately long; phallus long and slender, sinuate, basal 1/3 bulbous ventrally, apical 2/3 cylindrical, cornuti absent; valva moderately long, strongly sinuate, basal half broader than apical half, dorsobasal half with a large patch of dense, very long modified scales, rounded apices; sacculus shorter than cucullus, with a small patch of moderately dense, short setae basally, diffuse setae medially, with a rather small subtriangular lobe ventroapically, rounded apex projecting outward, without setae, followed by a moderately deep, narrow excavation; cucullus spatulate, strongly curved medially, margins rather parallel, truncated apically, with dense spiniform setae posteroventrally to apex, a longitudinal patch of very dense scale sockets and diffused short setae anteroventrally, ventrobasally with a wedge-shaped sclerotized part. Female genitalia (Fig. 17) with papillae anales broad, flat, densely setose; sternum VII with a narrow sclerotized line along anterior margin, posterior margin with a deeply U-shaped excavation medially; antrum V-shaped, moderately sclerotized; ductus bursae narrow, moderately long, shorter than corpus bursae, moderately sclerotized; ductus seminalis arising at entrance of corpus bursae; bulla seminalis present; corpus bursae large oval-shaped, with two thorn-like signa on sclerotized hollowed bases, smaller signum with pointed apex and the other larger with truncated apex.

Distribution. Thailand (Prachinburi province).

Etymology. The specific epithet ( sinuata = sinuate) refers to the outer margin of male hindwing.
