Nesochlamys contrarius Löcker  , sp. nov.

( Figs 8View FIGURE 8 D –G, 19)

Types. Holotype 3, AUSTRALIA, Qld: 26 km up Tinaroo Ck Rd via Mareeba, 29.ix.– 11.xi. 1983 (Storey & Brown) (QM T. 156366, originally from QDPI). Paratypes, Qld: 9 3, same data as holotype (7 in QDPI, 2 in ASCU); 1 3, same data, 24.viii.– 29.ix. 1983 ( QDPI); 1 3, GS 1 Mt Haig, 17.06 S, 145.36 E, 1150 m, malaise trap, 29.ix.– 31.x. 1995 (L. Umback) ( ANIC).

Etymology. The Latin term ‘ contrarius  ’ means ‘opposite’ and refers to a spine on the aedeagus which is bifurcated with its two branches curving in opposite directions.

Colour. Vertex light brown near basal emargination, mid to dark brown apically. Face mid (rarely dark) brown, carinae concolorous, except for pale lateral carinae of frons. Pronotum light brown, mesonotum dark brown. Forewings hyaline colourless with some light to mid brown patches; veins and tubercles concolorous with cells; apical parts of veins near pterostigma darkened; pterostigma light brown. Abdomen light to mid brown. Legs light brown, femora slightly darker.

Morphology. Body length: 3 3.2–3.6 mm.

Head: Vertex 0.7 –1.0 times as wide as long; with median carina covering 3 / 4 of length of vertex. Frons 1.4–1.7 times longer than wide. Rostrum just reaching hind coxae.

Thorax: Forewing 3.5–3.9 times longer than wide; with about 8–15 tubercles on costa; Sc+R forking basad or distad of fork CuA 1 +CuA 2; position of crossvein R-M basad or slightly distad of fork MA-MP; RP apically trifid; apical cells 10. Hind leg: 1 st tarsomere with 5–6 apical teeth; 2 nd tarsomere with 6 (rarely 5) apical teeth and three very fine setae.

Male genitalia: Anal tube as in Figs 19View FIGURE 19 C, 19 D. Genital styles ( Figs 19View FIGURE 19 E, F) apically with numerous fine setae. Ventromedian process of pygofer trapezoid with a shallow incision at the top ( Fig. 19View FIGURE 19 E). Aedeagus ( Figs 19View FIGURE 19 A, B): phallotheca left laterally with long spine (a) and large, bifurcated spine (b) with two branches curving in opposite directions; ventrally with long spine (c). Flagellum without spines.

Remarks. This species can be distinguished from the other Australian species by the presence of a large, bifurcated spine (b) with its two branches of equal length and curving in opposite directions ( Figs 19View FIGURE 19 A, B).
