Diagnosis. Imago (external). Wingspan: 10–11 mm (apo.).

Head, thorax, and ground colour forewing, including fringes: grey and blackish grey.

Forewing: relatively long.

Reniform stigma: bright, ovoid, yellow, outlined black.

Crosslines: all lines present, often broken, black, waved; terminal line marked by dense black interneural spots.

Hindwing: grey, discal spot absent.

Underside: forewing grey; hindwing grey, with indistinct discal spot.

Abdomen: grey.

Male genitalia. Tegumen, vinculum: inconspicuous.

Saccus: rounded apically.

Juxta-anellus plate: totally fused, arched, semi-globular; with hole for phallus, prominently displaced to left; at dorsal edge two, long, spinelike, parallel, narrow processes.

Valvae: slightly asymmetrical.

Ampulla: asymmetrical; large; like two plates, medially separated by deep cleft; dorsal left plate: ventrally and dorsally straight, basally and apically rounded; dorsal right plate: same but shorter; ventral left and right plates: broad-based, pick-axe-like, with almost equally long lobes (apo.).

Digitus: absent.

Phallus: long, narrow, tapered, curved 190º, coiled clockwise (apo.).

Vesica: unarmed.

Female genitalia. Posterior apophyses: 1.25 longer than anterior apophyses (apo.).

8 th abdominal segment: short, ringlike; connected by membrane to 7 th segment on dorsal and lateral sides; ventrally strongly fused with 7 th segment extended half way up 7 th segment.

7 th segment: on dorsal side 4 times wider than 8 th segment.

Antrum: narrow, conelike; ventral part half as long as on dorsal side (apo.).

Ductus bursae: membranous, very narrow, almost twice as long as corpus bursae.

Corpus bursae: globular; with cross shaped signum.

Differential diagnosis. D. pullata differs from other known Duplex species in having second longest forewing of genus, though only slightly shorter than in following species, blackish grey forewing, shape of ampulla and antrum, and length of ductus bursae.
