Varicopsella apecurvata View in CoL sp. nov.

( Figs. 13–18 View FIGURES 1 – 18 , 34–42 View FIGURES 34 – 42 )

Description: Length. ♂ 3.7–3.9 mm, ♀ 4.2–4.4 mm.

Head, pronotum, mesonotum and scutellum light brown, marked with dark brown lines and dots. Face light brown, with dark brown dots concentrated on dorsal half, eyes red brown ( Fig. 15 View FIGURES 1 – 18 ). Mesonotum with basal triangles ochre ( Fig. 13 View FIGURES 1 – 18 ). Forewing translucent light brown, with numerous small irregular dark spots ( Fig. 14 View FIGURES 1 – 18 ).

Body distinctly flattened dorsoventrally. Head including eyes wider than pronotum. Crown prominent, Vshaped in dorsal view. Face flat, longer than wide, lower half strongly inflated in male. Ocelli situated about 6 times closer to adjacent eyes than to each other ( Fig. 15 View FIGURES 1 – 18 ). Pronotum long and broad, slightly declivous, striations on surface dense and oblique. Mesonotum and scutellum together shorter than pronotum ( Fig. 13 View FIGURES 1 – 18 ). Hind tibia chaetotaxy PD 10, AD 8, AV 5. Forewings with 3 anteapical cells ( Fig. 14 View FIGURES 1 – 18 ).

Male genitalia. Pygofer broad, with 4–5 short spinelike distal processes on inner surface of lobe. Subgenital plate slender, parallel-sided, with scattered setae, dorsal setae longest ( Figs. 34, 35 View FIGURES 34 – 42 ). Aedeagus with preatrium weakly developed, shaft tubular, bent dorsally and evenly tapered to acute apex; in posterior view with atrium broadened near base with lateral margins evenly tapered dorsad, shaft slightly tapered toward rounded apex, gonopore subapical ( Figs. 36, 37 View FIGURES 34 – 42 ). Dorsal connectives divided into two sections, upper part long, curved laterad, with cheliform apex, ventral parts with a wide base and irregularly four-lobed apex in lateral view ( Figs. 39, 40 View FIGURES 34 – 42 ). Connective small, posterior margin truncate, with fingerlike protrusion in middle between dorsally bent anterolateral arms ( Figs. 41, 42 View FIGURES 34 – 42 ). Style relatively short and broad, apex abruptly tapered and upturned ( Fig. 38 View FIGURES 34 – 42 ).

Female. Body coloration and appearance similar to male ( Figs. 16–18 View FIGURES 1 – 18 ).

Material examined. Holotype: ♂, Australia: Queensland; Noonbah Station, SW of Longreach (GPS approx..); 24°4' S 143°11' E, 180 m, at house light, 6 Jan 2005, Coll. K. Hill, D. Marshall and M. Moulds (QM) GoogleMaps . Paratypes: 29♂♂ 7♀♀, same data as holotype ( INHS). GoogleMaps

Distribution. Australia.

Remarks. The new species resembles V. odentoidea Yang et al. , but can be distinguished from the latter by the number of pygofer distal processes and the shape of the dorsal connective.

Etymology. The new species name a combination of the latin word “ apex ” and “ curvatus ”, indicating that dorsal connective of this species has a curved apex.
