Xue, Guoxi, Qu, Peng, Li, Meng, Chiba, Hideyuki & Li, Wenwei, 2022, Molecular and morphological evidences confirm the statuses of Ancistroides othonias (Hewitson, 1878) and the subspecies of A. nigrita (Latreille, [1824]), sensu Evans 1949 (Lepidoptera, Hesperiidae), Zootaxa 5205 (5), pp. 481-490 : 486

Ancistroides nigrita diocles (Moore, [1866])

( Fig. 2 : An4, An5; Fig. 4 : An5; Fig. 5 : An4)

Nisoniades diocles Moore, [1866] : 787. Type locality: Bengal.

Kerana diocles: Distant 1886: 403 .

Ancistroides nigrita diocles: Evans 1949: 280 ; Chou 1994: 718; Gu & Chen 1997: 314; Kimura 2011: 65; Anonymous 2022; Inayoshi 2022.

This subspecies bears a larger body size: forewing length 24–26 mm (n = 6) in both sexes. Its male genitalia can be distinguished from those of the nominate subspecies and Ancistroides othonias by: distal part of valva wider, with its ventral edge arcuate; in lateral view, distal branch of valva higher than harpe; aedeagus longer, subzonal sheath and suprazonal sheath prominently bent; basal part and both branches of juxta much wider. The female genitalia ( Fig. 4 : An5) are different from those of A. othonias in: distal part of lamella antevaginal much wider in lateral view; lamella postvaginalis oval, gap on dorsal edge narrow and V-shaped.

Distribution. Sikkim, Bhutan, Assam, Bengal, N. Shan St., Karens, S. Guangxi, Hainan Island.
