Nesochlamys yiralli Löcker , sp. nov.

( Figs 10 A–C, 22)

Types. Holotype 3, AUSTRALIA, Qld: Mt Lewis, 14.–25.xi.1980 (R.I. Storey) (QM T.156369, originally from QDPI). Paratypes, Qld: 3 3, same data as holotype (1 in QDPI, 2 in ASCU).

Etymology. The term ‘ yiralli ’ means ‘root’ in Gooniyandi, an aboriginal language spoken in Western Australia ( Thieberger & McGregor, 1994) and refers to the shape of a spine on the aedeagus which resembles a root with tiny side-roots.

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

Morphology. Body length: 3 3.1–3.4 mm.

Head: Vertex 0.8–1.0 times as wide as long; with median carina covering 1/2–3/4 of length of vertex. Frons 1.4–1.5 times longer than wide. Rostrum not reaching hind coxae.

Thorax: Forewing 3.5–4.0 times longer than wide; with about 16–18 tubercles on costa; Sc+R forking slightly basad or at same level as fork CuA1+CuA2; position of crossvein R-M basad or at same level as fork MA-MP; RP apically bifid; apical cells 9–10. Hind leg: 1st tarsomere with 6 apical teeth; 2nd tarsomere with 6 apical teeth and three very fine setae.

Male genitalia: Anal tube as in Figs 22 C, 22D. Genital styles ( Figs 22 E, F) apically with numerous fine setae. Ventromedian process of pygofer trapezoid with a shallow incision at the top ( Fig. 22 E). Aedeagus ( Figs 22 A): phallotheca left laterally with two, long, intertwisted spines (a, b) and ventrally with long spine (c), bearing two short spines (d, e) pointing in opposite directions. Flagellum without spines.

Remarks. This species can easily be distinguished from all other Australian species of Nesochlamys by the presence of the long spine (c), bearing two short spines (d, e) pointing in opposite directions on the ventral side of aedeagus ( Figs 22 A, B).
