Zinga longa sp. nov.

(Figs 2, 4 f–o)

Description. Overall color pale grey, eyes grey; basal triangles of mesonotum dark; specimens from Australia (Figs 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 f–j); forewing infuscated on outer margin apically.

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

Pygofer side (Figs 2b, c) with two distal processes formed from outer surface, upper one finger-like, well pigmented, lower one lamellate, broad. Subgenital plate (Figs 2b, d) pigmented apically, narrow distally in ventral view, with about 2–4 macrosetae, marginal microsetae not differentiated in size. Style (Fig. 2e) widened subapically. Connective (Fig. 2f) U-shaped, lateral arms slender, central lobe rounded, very short. Aedeagus (Figs 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), and the aedeagal processes shorter (Fig. 2h). The transition from vertex to face has the paired white (translucent) areas more distinct in the paratypes (Fig. 4o) than in holotype (Fig. 4j). 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) . Paratypes: 1³, AUSTRALIA: QLD ca. Mal- anda, Rose Gum Retreat, 17.3114ºS, 145.6998ºE, 750m, 24 ii 2015, coll . 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) .

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.
