( Figs. 4 , 15 )

Holotype. INDIA: ♂, Manipur, Shirui Hills (Site 3), 25.11715°N 94.44560°E, 2190m, 13.IX.2019, coll. JS Irungbam / IJ3135 / Genitalia slide: 267 / HK15-15. The holotype is deposited in the collections of NZC, ZSI.

The BOLD Process ID. NMJI 011-23, BIN: AAG0653.

Paratype: None.

Diagnosis. The new species, A. manipura sp. nov. ( Fig. 4 ), is very similar to A. himalaya ( Fig. 10 ), in the wing pattern but differs in the ground colour of the forewing, which is darker than the lighter grey base colour, and the reniform stigmata is filled with golden flaw in A. himalaya ( Fig. 10 ). Based on the male genitalia, the new species belongs to the A. infausta group due to the structure of the basal diverticulum of the vesica. Compared to those of A. himalaya ( Fig. 18 ), the male genitalia of A. manipura sp. nov. ( Fig. 15 ) has the much narrower and less curved uncus, the slightly more elongated tegumen, the broader juxta, harpe much shorter than valva, carina with strong toothed field, vesica recurved at the base, and bearing a smaller diverticulum with three further, smaller diverticuli, which are covered with dense cornuti.

Description. Adult ( Fig. 4 ). Forewing length: 23 mm in male. Antennae threadlike. Palps dark grey, few white scales at ends. Forehead dark brown center, white hair on edges and dorsal side. Collar dark brown, white dorsal edge. Tegulae, thorax mix of white, brown, black scales. Forewing dark grey, black markings scattered white scales. Postmedial/antemedial lines black, wide, double, blurred, zigzag. Reniform/orbicular stigmata unclear. Hind wing dark brown, faint veins, no cell spot. Cilia near veins lighter. Male genitalia ( Fig. 15 ). Uncus long, thin. Tegumen short, broad, small, rounded lobes. Vinculum V-shaped, twice as long. Proximal valva wider, sclerotized, tapers at harpe. Cucullus round, sparsely haired. Harpe broad at base, sclerotized, curved, shorter than cucullus. Sacculus flat, almost straight. Clavus simple. Aedeagus short, broad. Carina crescent-shaped, toothed lateral fields. Vesica recurved, small diverticulum at base. Three smaller diverticula with dense cornuti fields. Female unknown.

Genetic information ( Fig. 21 ). Only the holotype of A. manipura sp. nov. has been sequenced and assigned the BIN BOLD: AAG0653. The intraspecific divergence ranges could not be calculated. The nearest neighbour of the species is A. nitida (wrongly identified as A. caliginea in BOLD: GBGL12794-13| Anacronicta_caliginea |COI- 5P| JX411792 ), with pairwise distances in the range of 4.25%.

Etymology. The name of the new species refers to “ Manipur ”, the state of India where the type specimen was collected.

Distribution. India — Manipur.
