Diagnosis. Palpita incesta sp. nov. is morphologically similar to P. inusitata (Butler), but can be distinguished by the following characters: ground color of wings grayish white (Fig. 1); in male genitalia, sacculus not projected at distal 1/3 (Fig. 3); in female genitalia, ductus bursae entirely sclerotized, except for partly membranous laterally and folded at middle (Fig. 5). In P. inusitata, ground color of wings white (Fig. 2); in male genitalia, sacculus projected at distal 1/3 (Fig. 4); in female genitalia, ductus bursae membranous overall, except for partly sclerotized near antrum and not folded at middle (Fig. 6).
Description. Adult (Figs. 1–4). Length of forewing 10–11 mm in both sexes. Vertex covered with grayish white scales; frons flat, covered with grayish white scales; antenna filiform; chaetosema absent; labial palpus upturned, brown, mixed with grayish-white scales; proboscis brown, mixed with grayish-white scales. Patagium and tegula grayish white. Ground color of forewing grayish white; costal margin brownish orange; basicellular dot brownish orange; midcellular mark brownish orange, semicircular, edged with brown line; infracellular mark brownish orange, edged with brown line; discal mark brownish orange, reniform, edged with brown line; subterminal fascia brown, irregularly undulate; terminal area with two brown dots at R 5 and M 1; fringe grayish white. Ground color of hindwing grayish white; basal area with a brown dot; posterior discal dot brownish orange, irregularly ovoid, edged with brown line, with black dot at 1/3 of M 2; subterminal fascia brown, irregularly undulate; terminal area with three brown dots at Rs, M 1, CuP; tornal dot brown; fringe grayish white (Fig. 1). Abdomen slender, grayish white (Fig. 1).
Male genitalia (Fig. 3). Uncus rod–shaped, widened at base; valva ovoid, weakly sclerotized from basal to postmedian area, sparsely setose at apex; costa arched, strongly sclerotized; sacculus strongly sclerotized, expanded near apex of valva, tip of sacculus pointed; juxta lobate, strongly sclerotized; saccus small, U-shaped; phallus cylindrical, sclerotized ventrally, almost same length as valva, with one long and two short, thorn-like cornuti (Fig. 3). Female genitalia. Papilla anales simple, setose; posterior apophyses about half length of anterior apophyses; antrum broad, sclerotized; ductus bursae about 3 times length of corpus bursae, sclerotized overall, except partly membranous at laterally, swollen near antrum and strongly curved, folded at middle; corpus bursae ovate, with a pair of spine-shaped signa (Fig. 5).
Distribution. Laos (Ban Tha).
Etymology. The specific name is derived from the Latin incesta, referring to the cloudy wings of the adults.
