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 : 486-487

Ancistroides fumatus (Mabille, 1876)

( Fig. 2 : An10, An11; Fig. 4 : An11; Fig. 6 )

Tagiades fumatus Mabille, 1876: 271 . Type locality: Philippines.

Kerana pravha Fruhstorfer, 1911 . Type locality: Bazilan.

Ancistroides nigrita fumatus: Evans 1949: 280 ; de Jong & Treadaway 1993: 36; de Jong & Treadaway 2007: 34; de Jong & Treadaway 2008: 7, pl. 18, figs. 14–16.

The length of forewing is about 23 mm (n = 2) in male and 25 mm (n = 1) in female. On the ventral side of both wings, the submarginal and marginal area are uniformly pale, similar to Ancistroides nigrita .

Male genitalia ( Fig. 6 ) can be distinguished from those of Ancistroides othonias ( Fig. 3 ) and A. nigrita ( Fig. 5 ) by the following characters: in lateral view, uncus as long as tegumen, lower branch hooked and well developed; transverse part of gnathos obviously longer than longitudinal part; each side of uncus curved inwards in dorsal view, distal half V-shaped; in lateral view of valva, dorsal edge wavy, distal edge protrudent; harpe rubost and tapered; distal branch of valva finger-like and pointed in lateral view, while bifid and decorated with tiny spines in dorsal view, its distal triangular lobe much wider; suprazonal sheath of aedeagus bent downwards; juxta with deeper furcation, basal edge flat.

Female genitalia ( Fig. 4 : An11) are similar to those of Ancistroides othonias ( Fig. 4 : A98) and A. nigrita ( Fig. 4 : An5), but can be recognized by: distal part of lamella antevaginal elongated and tapered into a blunt point in lateral view; distal edge of lamella postvaginalis deeply concave.

Distribution. Philippines.
