Ancistroides nigrita nigrita (Latreille, [1824])

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 : 485-486

Ancistroides nigrita nigrita (Latreille, [1824])

( Fig. 2 : A97; Fig. 5 : A97)

Hesperia nigrita Latreille, [1824] : 788. Type locality: Java.

Kerana vasuba Fruhstorfer, 1911 . Type locality: Java.

Ancistroides nigrita nigrita: Evans 1949: 280 .

Ancistroides nigrita maura: Eliot 1992: 355 (misidentification).

On the ventral side of both forewing and hindwing of Ancistroides nigrita , the submarginal area and the marginal area are uniform, paler than the inner area.

In the nominate subspecies, the forewing length is 21–23 mm (n = 1) in male ( Evans 1949). The male genitalia ( Fig. 5 : A97) are similar to those of Ancistroides othonias , except for: harpe elongated, reaches dorsal edge of valva; distal branch of valva thicker and finger shaped in lateral view, with a wider distal triangular lobe in dorsal view; subzonal sheath of aedeagus longer and more bent upwards in lateral view.

Remarks. Eliot (1992) stated that “(in maura ) the marginal areas of both wings are broadly paler on the underside”. This description is contradictory with that by Evans (1949). Judging from the photos ( Eliot 1992: plate 55, fig. 6, 7), the taxon examined by Eliot (1992) should belong to Ancistroides nigrita nigrita .

Distribution. Malay Peninsula, Java.
