Diagnosis. Fully winged female (Figs 1, 2); palpal formula 6/3; 2r-rs&Rs vein of forewing with distal part much longer than proximal part (Figs 1, 2); protarsus chelate (Fig. 2); chela without rudimentary claw (Fig. 4); enlarged claw without subapical tooth, with inner side provided with one row of six small lamellae (Fig. 4); tibial spurs 1/1/2.
Description of female holotype. Fully winged (Figs 1, 2); length 3.9 mm. Head black, except mandible brown; antenna brown, except ventral side of scape whitish; mesosoma black; metasoma brown; legs testaceous, except part of coxae and clubs of femora brown. Antenna slightly clavate, without ADOs; antennomeres in following proportions: 12:4:16:12:10:10:9:9:8:13. Head (Fig. 3) shiny, slightly swollen, punctate, unsculptured among punctures, more strongly punctate on frons; frontal line complete, more protruding in anterior third of frons; occipital carina complete, laterally not reaching eyes; POL = 1.6; OL = 1.1; OOL = 3.2; OPL = 3.5; TL = 1.7. Palpal formula 6/3. Pronotum shiny, with disc punctate, unsculptured among punctures; anterior collar rugose; pronotal tubercle reaching tegula. Mesoscutum shiny, punctate, unsculptured among punctures. Notauli incomplete, reaching about 0.8 × length of mesoscutum (Fig. 1). Mesoscutellum shiny, slightly punctate, unsculptured among punctures. Metanotum shiny, unsculptured. Metapectal-propodeal complex dull, reticulate rugose, without transverse or longitudinal keels. Mesopleuron dull, partly rugose and partly punctate. Metapleuron dull, reticulate rugose. Forewing hyaline, without dark transverse bands (Figs 1, 2); 2R1 cell open; 2r-rs&Rs vein with distal part much longer than proximal part (25:12). Protarsomeres in following proportions: 12:3:4:24:34. Protarsomere 2 produced into hook. Enlarged claw (Fig. 4) without subapical teeth, with one row of six small lamellae (shorter than enlarged claw breadth). Protarsomere 5 (Fig. 4) with two rows of about 42 lamellae; distal apex with group of 11 lamellae, one of which very long. Rudimentary claw absent. Tibial spurs 1/1/2.
Male. Unknown.
Hosts. Unknown, but probably leafhoppers (Hemiptera: Auchenorrhyncha) feeding on Nothofagus (see final discussion).
