Figs 2A–C, G–I

Diagnosis. Agrioglypta ubaidillahi sp. nov. is easily distinguished from the closest species, A. naralis , by a brown trapezoidal medial band on the forewing which runs from costa to dorsum, followed by a yellowish U-shaped, wider and white band and white fringe at the middle of the termen ( Fig. 2A ). The brown trapezoidal medial band of the forewing of A. naralis is narrower. Moreover, the yellowish U-shaped band of A. naralis is more or less equilateral and the termen with yellow fringe at middle ( Fig. 2D ). In addition, the base of fibula of male genitalia of this new species arise from the mid of costa and the juxta strongly sclerotized. On the other hand the base of fibula of A. naralis arise from the mid of valva and the juxta less sclerotized ( Figs 2B–C, E–F ).

Description. Male ( Fig. 2A ): Forewing length 10 mm. Head with frons with black scales at middle and yellowish-white at edge and vertex black. Labial palpus white at base, black at middle, and yellowish-white at tip. Maxillary palpus prominent, black except at third segment yellowish-white. Proboscis white. Antennae filiform, extending to approximately full forewing length, dorsal surface with longitudinal row of black scales, and ventral surface with minute yellow cilia. Thorax black dorsally, white ventrally, patagia black with white scales at middle and tegulae white. Legs yellowish-white except for foretibia and epiphysis covered with black scales. Forewing triangular, yellowish-white terminal cilia with black scales at apex and tornus. Hindwing with a yellow thin discal bar and yellowish-white fringe running from Sc+R 1 towards CuA 1. Abdomen slender, first segment toward 8 th black gradually fading to dark brown, ventral 9 th segment has dense black tuft scales, curved upwards to cover anal lobe.

Male genitalia ( Figs 2B, C ). Tegumen subtriangular, subscaphium weakly sclerotized, uncus curved dorsoventrally, medially narrow and distally blunt extending just beyond apical valva. Valva leaf-shaped, costa slightly sinuate, ventrally with scattered distal piliform scales. Fibula curved inwards, sharply pointed apically. Coremata moderate, almost as large as valva, with weak, lamellar scales. Vinculum simple, keel-shaped. Phallus long and thin, approximately three times length of abdomen.

Female ( Fig. 2G ): Similar to male, except for yellow scales of 9 th segment which cover anal lobe.

Female genitalia ( Figs 2H, I ): Anal lobe ovate, with faint scattered piliform scales; anterior long, almost equal to posterior apophyses; entrance to ostium bursae wide, very membranous; antrum short, less than length of anterior apophyses, weakly sclerotized; ductus bursae very thin and long (more than 20 times of corpus bursae); corpus bursae globular with a pair rounded signa with denticules.

Etymology. The specific name ubaidillahi is dedicated to Rosichon Ubaidillah for his dedication in leading the expedition to Sulawesi that resulted this new species. A noun in the genitive case.

Distribution. Mountain Mekongga, Southeast Sulawesi and Central Sulawesi ( Fig. 4 ).

Remark: Adults were collected using a light trap at altitude> 1449 m. above sea level.
