Holotype (female) Indonesia, Papua: New Guinea, NE., Swart Valley, Karubaka, 1450 m, [3° 35' S, 138° 30' E], 17.XI.1958, J.L. Gressitt, depository: Bernice P. Bishop Museum, Honolulu, Hawaii, USA ( BPBM). GoogleMaps

Paratype: 1 female, same locality, 1500 m, 20.XI.1958, J.L. Gressitt ( BPBM) .

Diagnosis. The new species is unique for the peculiar shape of the female subgenital plate with a pair of transverse basal furrows followed by transverse folds and with long and strongly curved apical lobes ( Figs. 432, 525). The coloration of the pronotum is also conspicuous but might be variable. Differences to other species are outlined in the key.

Description. Fastigium verticis in front of eyes 1.5 mm, from base 1.8 mm; dorsal eye length 1.4 mm; greatest diameter of eye 1.6; mm; index fastigium verticis from base: eye length 1.3. Face rugose but shining. Tegmen reaching apices of hind femora; gradually narrowed behind basal widening; apex narrowly rounded. Femora with the following number of spines on ventral margins: fore femur 6–7 external, 6 internal; mid femur 6 external, 2–3 internal near base; hind femur 9–10 external, 0 internal.

Male unknown.

Female. Tenth abdominal tergite furrowed in midline. Epiproct triangular with obtuse apex; surface almost flat. Subgenital plate divided in midline by a triangular membranous area; with a large transverse furrow at each side; lateral margins with obtuse swelling; apical half divided into two acute horns curved dorsad ( Figs. 432, 476, 525).

Coloration. Medium brown. Face with black band between eyes and with black vertical band widening ventrad. Pronotum with disc dark brown along fore and hind margins, that along fore margin widening in middle and including two oval yellow spots. Tegmen with dark cells and light veinlets.

Measurements (2 females): body 27–28; pronotum 7.0–7.2; tegmen 21–22; hind femur 16.5–18.0; ovipositor 18–19 mm.

Etymology. Named for the strongly curved lobes of the female subgenital plate.
