Paratypes. 3 males, 1 female. 2 males, 1 female, Australia, Queensland, Brisbane , 14.iv.1904, 28.iv.1906, and 2.iv.1908, leg. A. J. Turner, genit. preps 6085 and 6087 M. Fibiger, [male specimen from 2006 without abdomen; male from 2004 with white label: Micromelas trispila Turner, TYPE, - not published] ; 1 male, Australia, Queensland, 3 km NE Ravensbourne , 27º21’S 152º11’E, 11.iv.1997, leg.

Diagnosis. Imago (external). Wingspan: 11–12 mm (apo.).

Head, thorax, and ground colour forewing, including fringes: greyish black.

Forewing: long and broad, subterminal area grey (apo.).

Reniform stigma: bright yellow, ovoid, outlined black.

Crosslines: all lines present, black, terminal line marked by dense black interneural spots.

Hindwing: light grey, discal spot absent.

Underside: forewing blackish 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 and right plate: ventrally straight, dorso-basally with a rounded hump, basally and apically rounded; dorsal left and right plate: pick-axe-like, with long and narrow dorsal lobe, and short ventral lobe (apo.).

Digitus: absent.

Phallus: long, narrow, tapered, curved 250º; coiled clockwise (apo.) [normally, though S-shaped in preparation].

Vesica: unarmed.

Female genitalia. Posterior apophyses: 1.5 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, less than half as long on dorsal side (apo.).

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

Corpus bursae: globular, with cross-shaped signum.

Differential diagnosis. D. cocking differs from other Duplex species in longer and broader wings, largest wingspan of all known Duplex species in and outside Australia, black forewing with grey subterminal area; differently shaped ampulla plates; coil of phallus; proportion between anterior and posterior apophyses; and shape of antrum.

Distribution. D. cocking is known from Australia, south-western parts of Queensland and northern part of New South Wales.
