Ammatho (Ammathella) shingwa Volynkin & S.-Y. Huang in Huang et al., 2020, Zootaxa 4809 (3): 587, figs 9-10, 20, 25 (type locality: "Myanmar (Burma), 50 km E Putao, env. Nan Thi village, 950 m").

Type material examined.

Holotype: male, Myanmar (Burma), 50 km E Putao, env. Nan Thi village, 950 m, 11-16. V.1998, leg. Murzin & Sinjaev, slide ZSM Arct. 2019-806 Volynkin (MWM/ ZSM). Paratypes: 1 male, 1 female with the same data as in the holotype, slide ZSM Arct. 2019-821 (male) Volynkin (MWM/ ZSM); 1 female, Myanmar (Burma), 50 km NE Putao, Wa Sa Dam village, 950 m, 17.V.1998, leg. Murzin & Sinjaev, slide ZSM Arct. 2019-822 Volynkin (MWM/ ZSM).

Diagnosis.

The forewing length is 11.5 mm in males and 12.5-13.5 mm in females. Ammathella shingwa is externally reminiscent of A. gesar , A. lhoba , and A. monpa but is clearly different by the ochreous abdomen, the markedly narrower reddish pattern elements on the forewing, the thinner postmedial line, and the yellowish hindwing only slightly suffused with pink scales in the submarginal area, whereas in the similar congeners, the abdomen is pinkish with admixture of blackish scales distally, the reddish pattern elements are broad, and the hindwing is pinkish. The male genitalia of A. shingwa are most similar to those of A. midzhan and A. lhoba due to sharing similar short phallus. However, the species can easily be distinguished from A. midzhan and the externally similar congeners by the distally dilated valva with a longer and broader trapezoid basal section of the sacculus and the vesica lacking a medial semiglobular diverticulum with a cluster of cornuti and thoroughly covered with granulation. The female genitalia of A. shingwa differ from those of the congeners in the broader antrum, the broader corpus bursae with a smaller signum, and the larger and more heavily sclerotised appendix bursae.

Distribution.

Known from northern Myanmar (Kachin State).
