Specimens examined

Yunnan: 2♂♂, Yulongshan (3500 m), Lijiang, 20 July 1984, leg. SY Wang ( IZAC) ;

Sichuan: 3♂♂ 4♀♀, Wolong (1940 m), 17 July 1982, leg. JG Yang.

Diagnosis

This species resembles D. kimminsi (Carpenter) in appearance, but can be separated from the latter by the basal branch of paramere hooked; the mesal branch densely

covered with microsetae along inner margin; female genital plate with paired auricular lateral processes along lateral margins.

Redescription – male

Body and head yellowish brown; ocellar triangle black. Rostrum with two black lateral longitudinal stripes.

Thorax. Nota yellowish brown, with two black lateral longitudinal stripes. Legs pale yellow ( Figure 8A ).

Wings. Forewing length 13.0 mm, width 3.5 mm; membrane hyaline, only with an indistinct apical band. Hindwing length 12.0 mm, width 3.0 mm, similar to forewings ( Figure 8A ).

Abdomen. Terga I–V with two lateral black longitudinal stripes. Tergum VI with a pair of clavate anal horns ( Figure 8A ).

Male genitalia. Genital bulb oval. Epandrium slightly constricted at middle, with the apex deeply emarginate ( Figure 9A ). Hypovalves broad, with the rounded apex reaching the base of gonostylus ( Figure 9B ). Gonostylus slightly curved, with a small triangular median process and an acute basal process along the inner margin. Parameres trifurcate, with the basal branch hook-like, moderately long and curved ventrally; the lateral branch very long, extending beyond the basal process of gonostylus, with the basal part weakly chitinous; the mesal branch with dense microsetae along inner margin. Ventral valves of aedeagus stout and blunt; dorsal valves longer, with sparse black long setae ( Figure 9C, D ).

Redescription – female

Forewing length 14.5 mm, width 4.0 mm. Hindwing length 14.0 mm, width 3.5 mm. The apical band more prominent than in males ( Figure 8B ).

Female genitalia. Subgenital plate broadest at base, constricted near middle, terminating in a truncated ligulate process with black setae ( Figure 9E ). Genital plate broad, with the main plate approximately rectangular and bearing paired auricular lateral processes. Posterior arms short, rounded apically. Axis short, slightly expanded apically ( Figure 9 F–H).

Distribution

China (Yunnan and Sichuan Provinces) .
