Figs 1A–C, G–I

Diagnosis. Agrioglypta hastantiae sp. nov. is easily distinguished from the closest species A. excelsalis ( Walker, 1866) by a black trapezoidal medial line on the forewing, running from the mid-costa towards the end of the discal cell, and continues with a white ovate band as well as a black-tinged at both edges from M 3 towards CuA 2 and turned into whitish-yellow from CuA 2 toward the dorsum ( Fig. 1A ). On the other hand, a dark triangle medial line of the forewing on A. excelsalis continuously run from the mid-costa towards the dorsum ( Fig. 1D ). In addition, the male genitalia of this new species shows uniquely dense scaled at central and margin part of valva and the tip of fibula recurved ( Fig. 1B ).

Description. Male ( Fig. 1A ): Forewing length 7 mm. Head with frons black at middle, white-yellowish edge, and vertex black. Labial palpus subascending with long, rough black scales, yellow-tinged from middle to apex, and white scales at ventral from middle to basal. Maxillary palpus prominent, first and third palpomeres covered with yellow scales, while second has black scales. Proboscis white and well-developed. Antennae filiform, extending to approximately full forewing length, while dorsal surface covered with a longitudinal row of black scales, ventral surface with minute yellow cilia. Thorax black at dorsal and white at ventral part, patagia black with white scales at middle and yellowish-white tegulae. Legs white, epiphysis covered with black scales. Forewings triangular, with white terminal cilia and dark scales at apex and tornus. Hindwing with a yellow straight discal bar and a snow white fringe running from tip of Sc+R 1 toward tip of CuA 1. Abdomen slender, with first segment towards 8 th black to dark brown gradually, 6 th segment bears pair of black pencils setae, while ventral 9 th segment bears a bundle of black tuft scales, curved upwards to cover anal lobe.

Male genitalia ( Figs 1B, 1C ): Tegumen subtriangular, subscaphium slightly sclerotized; uncus simple, weakly sclerotized with a narrow triangular base, medially narrow, curved subdistally and apically blunt, not extended at apex of valva; valva simple, semirectangular, center of ventral part with densely scaled as well as margin of valva; fibula never exceeding valva length, curved inwardly, pointed apically; juxta prominent, tongue-shaped, weakly sclerotized; vinculum simple, semicircular. Coremata large, ovate, with a bundle of lamellar scales, almost twice size of valva. Phalllus long and thin, more than three times length of abdomen.

Female ( Fig. 1G ): Similar to male, except for yellow scales on 9 th segment over anal lobe

Female genitalia ( Figs 1H, I ): Anal lobe ovate with scattered faint scales; lamella postvaginalis moderate sclerotized; posterior apophyses short, anterior apophyses length almost double of posterior apophyses; ostium bursae wide, membranous, antrum short, never reached tip of anterior apophyses; ductus bursae thin and long; corpus bursae globular with a pair of oval signa with denticules.

Etymology. The specific name hastantiae is derived from the wife’s name of the senior author, Hari Sutrisno. This name is dedicated to her support during our preparing this manuscript. A noun in the genitive case.

Distribution. Papua to Sulawesi, Ternate Island ( Moluccas), Bali and Sumatra ( Fig. 4 ).

Remark: The wing scales on the first paratype female shown in Fig. 1G were damaged while mounting the specimen leading to the loss of wing colors compared to males. Adults are nocturnal..
