Daplasa medoga An, Da, Wang & Wang sp. nov.

( Figs 1–2 View FIGURES 1–4 , 5 View FIGURES 5–7 , 8 View FIGURE 8 )

Diagnosis. The new species is similar to D. irrorata and D. nivisala in wing patterns ( Figs 1–4 View FIGURES 1–4 ), but can be easily separated from them by the male genital characters: in D. medoga sp. nov., uncus sagittate, gnathos shorter, with a flattened apex, valvae broadly crotched distally and aedeagus with a long and spiculate cornutus ( Fig. 5 View FIGURES 5–7 ); in D. irrorata , uncus bifurcate, gnathos long and well-sclerotized, apical portion furcate, valvae with a well-developed projection at dorsal margin and aedeagus without cornutus ( Fig. 6 View FIGURES 5–7 ); in D. nivisala , uncus bifurcate, gnathos nearly triangular and valvae approximately rectangular ( Fig. 7 View FIGURES 5–7 ).

Description. Male adults ( Figs 1–2 View FIGURES 1–4 , 8 View FIGURE 8 ). Forewing length 9–10 mm.

Head: Antenna bipectinate, pale yellow; frons and vertex covered with creamy-white bristles; compound eyes large; labial palpus yellow, porrect.

Thorax: Yellowish-white mixed with some brown scales dorsally, ventrally cream; tegula ochre. Forewing pale whitish yellow; scattered with blackish grey to grey spots along the leading edge, inner edge and outer edge but more in the basal area; a grey oblique band from 2/3 of the inner margin to apex; R 1 and R 2 almost parallel; R 3 + 4 branching from near the basal 1/3 of R 5; M 1 arising from upper angle of discal cell; M 2 and M 3 separated each other, arising from the lower angle of discal cell, respectively; CuA 1 and CuA 2 approximately parallel; fringe pale whitish yellow, mixed with dark grey scales. Hindwing pale yellow; Rs and M1 short stalked; M2 and M3 separate, arising from the lower angle of discal cell. Legs pale whitish yellow; fore femur yellow ventrally, fore tibia with yellow scales laterally; hind tibia with two whitish yellow spurs, hind tarsus with black scales distally.

Male genitalia ( Fig. 5 View FIGURES 5–7 ). Uncus broad, sagittate; gnathos small, with a flattened apex; valvae broadly crotched at distal part, forming two lobes, the dorsal part large, apically round, the ventral part relatively small, slightly bent, apically acute; saccus small; aedeagus robust, slightly bent, broadened in basal half, with a long and spiculate cornutus.

Female. Unknown.
