Diagnosis. Agrioglypta halimunensis sp. nov. is easily distinguished from A. jaculalis ( Snellen 1894) by a post medial line with three alternate bands: yellowish white, gray, and dark brown scales and the margin with yellowish white scales at middle. Moreover, the hindwing of this new species with a dark brown scales at middle area between M 3 and CuA 1 ( Fig. 3A ). The male genitalia of this new species with dense and piliform scales at ventral part of a simple valve, and the uncus never extended beyond the valva. On the other hand, the valva of A. jaculalis with a strong frame a costa and the uncus always extended beyond the valva ( Figs 3B–C, E–F ).

Description. Male ( Fig. 3A ). Forewing length 7 mm. Head with frons partly with black scales at middle and yellowish-white at edge and vertex black at middle and white-yellowish at edge. Labial palpus white at base, black at middle, and white-yellowish at tip. Maxillary palpus prominent, black except at third segment white-yellowish. Proboscis white.Antennae filiform extending approximately full forewing length, dorsal surface covered a longitudinal row of black scales, and ventral surface with minute yellow cilia. Thorax black dorsally, white-ochreous ventrally, patagia black with white scales at middle. Tegulae black at middle and white at edge. Legs white-ochreous. Forewing triangular with yellow termen, surrounded by black scales, and terminal cilia ochreous. Hindwing with a prominent, yellowish-brown sickle-shaped of discal bar and a yellowish-white fringe running from Sc+R 1 towards CuA 2. Abdomen slender, first segment towards 8 th white ochreous with black to dark brown tinged scales, ventrally 9 th segment with dense grey scales, curved upwards cover anal lobe.

Male genitalia ( Figs 3B–C ). Tegumen subtriangular, subscaphium weakly sclerotized, uncus curved dorsoventrally, apically blunt, reaching at half of valva. Valva simple, leaf-shaped, with dense long piliform scales ventrally, fibula curves inwards, with a sharp apex. Coremata large with a weak bundle of lamellar scales, easily detached during slide mounting. Vinculum simple, keel-shaped. Phallus long (more than ten times of length of valva) and thin.

Female ( Fig. 3G ). Similar to male, except for ventral yellow scales of 9 th segment which cover anal lobe.

Female genitalia ( Figs 3H–I ). Anal lobe ovate with faint piliform scales, posterior apophyses short, half length of anterior apophyses. Ostium bursae moderately wide; antrum weakly sclerotized, short, approximately a quarter of 8 th segment; ductus bursae thin and long (more than 20 times of corpus bursae), corpus bursae globular, a pair of oval signa with minute, pointed denticules.

Etymology. The specific name halimunensis is derived from the type locality. This new species is endemic to Halimun, West Java. An adjective in the nominative singular.

Distribution. Mountain Halimun–Salak National Park (TNGHS), West Java only (Fig. 13).

Remark: The male holotype forewing showed damages. The lamellar coremata bundle was damaged during slide mounting due to its soft nature, nevertheless, a small part remains on both sides. The adults were collected using a light trap at altitude> 1400 m above sea level.
