description: <i>Duplex cockingi</i> Fibiger, new species (Plate 11, figure 1, 2; male genit. plate 20, figure 5; female genit. plate 26, figure 3) <b>Material examined.</b> Holotype. Male, Australia, New South Wales, 11 km SW Narrabri, 30’26S 149’41E, 9.iv.2008, leg. G. Cocking, genit. prep. 6084 M. Fibiger, coll. ANIC. 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: <i>Micromelas trispila</i> Turner, TYPE, - not published]; 1 male, Australia, Queensland, 3 km NE Ravensbourne, 27º21’S 152º11’E, 11.iv.1997, leg. I. F. B. Common, genit. prep. 6086 M. Fibiger. Colls. ANIC, G. Cocking, and M. Fibiger. <b>Diagnosis. Imago (external).</b> 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. <b>Male genitalia.</b> 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. <b>Female genitalia.</b> 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. <b>Differential diagnosis.</b> <i>D. cocking</i> differs from other <i>Duplex</i> species in longer and broader wings, largest wingspan of all known <i>Duplex</i> 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. <b>Distribution.</b> <i>D. cocking</i> is known from Australia, south-western parts of Queensland and northern part of New South Wales.
