Zinga longa View in CoL sp. nov.

( Figs 2 View FIGURE 2 , 4 View FIGURE 4 f–o)

Description. Overall color pale grey, eyes grey; basal triangles of mesonotum dark; specimens from Australia ( Figs 4 View FIGURE 4 k–o) with vertex, face except gena and fore margin of pronotum yellow, tip of anteclypeus brown; specimen from Papua New Guinea without such markings ( Figs 4 View FIGURE 4 f–j); forewing infuscated on outer margin apically.

Male 2S abdominal apodemes ( Fig. 2a View FIGURE 2 ) not reached hind margin of sternite IV.

Pygofer side ( Figs 2b, c View FIGURE 2 ) with two distal processes formed from outer surface, upper one finger-like, well pigmented, lower one lamellate, broad. Subgenital plate ( Figs 2b, d View FIGURE 2 ) pigmented apically, narrow distally in ventral view, with about 2–4 macrosetae, marginal microsetae not differentiated in size. Style ( Fig. 2e View FIGURE 2 ) widened subapically. Connective ( Fig. 2f View FIGURE 2 ) U-shaped, lateral arms slender, central lobe rounded, very short. Aedeagus ( Figs 2 View FIGURE 2 g–i) with very long apical processes, not fused to each other.

Diagnosis. The new species can be distinguished from the other species by the wider, lamellate lower process of the pygofer side, rounded connective central lobe and the longer, separated apical processes of the aedeagal shaft.

Notes. The paratype specimens from Australia are larger than the holotype from Papua New Guinea, and have the pygofer lower process slightly longer ( Fig. 2c View FIGURE 2 ), and the aedeagal processes shorter ( Fig. 2h View FIGURE 2 ). The transition from vertex to face has the paired white (translucent) areas more distinct in the paratypes ( Fig. 4o View FIGURE 4 ) than in holotype ( Fig. 4j View FIGURE 4 ). We consider this variation to be intraspecific.

Measurement. Male length of specimen from Papua New Guinea 4.85mm; those from Australia 5.40– 5.65mm.

Material examined. Holotype ³, PAPUA NEW GUINEA, Gulf, Ivimka Res. Station, Lakekamu Basin , 120m, 7°44'S, 146°30'E, 01–05 iii 2000, Malaise trap, coll. T. Sears ( UCD) GoogleMaps . Paratypes: 1³, AUSTRALIA: QLD ca. Mal- anda, Rose Gum Retreat , 17.3114ºS, 145.6998ºE, 750m, 24 ii 2015, coll GoogleMaps . CH Dietrich, Hg vapor light in 2º, rainforest, AU 15-18-1 ( INHS) ; 2³, same data as holotype except 26 ii 2015, AU 15-18-4 ( INHS) GoogleMaps .

Etymology. The new specific epithet is derived from the Latin adjective “ longus ” which means “long”, referring to the long apical processes of the aedeagal shaft.
