DISTRIBUTION — Papua New Guinea.

DIAGNOSIS — Second tergite with coarse and irregular longitudinal rugae.

DESCRIPTION (Holotype) — FEMALE: body length 4.5 mm, length of fore wing 3.8 mm. Head. Antennal segments 37, scapus 1.43x as long as wide, shortened ventrally, F1/F2 = 1.00, length of first and second flagellomeres 1.50x their width, penultimate flagellomere 1.67x its width, apical flagellomere with apical spine; maxillary palp 0.40x height of head; ED/ TD = 4.40; OOL:OD:POL = 8.00:4.00:3.00; occipital carina absent; vertex, frons smooth with numerous spaced setae; frons with medio longitudinal groove in front of anterior ocellus; face weakly convex in lateral view, 1.20x larger than long in front view, smooth; gena smooth; MS/BM = 1.80, malar sulcus fine and straight; face with fine setae. Mesosoma. HMS/ LMS = 0.73; mesopleuron, metapleuron smooth; mesoscutum with fine setae; lobes of mesoscutum smooth; precoxal sulcus only weakly impressed medially; notauli impressed only anteriorly, smooth; scutellar sulcus 5.00x wider than medially long, with 5 longitudinal carinae; scutellum smooth, sparsely punctate, weakly convex in lateral view; propodeum smooth, median longitudinal propodeal carina complete, running within a distinct groove. Legs. Length of femur, tibia and basitarsus of fore leg 5.40, 6.50 and 8.50x their width, respectively; length of femur, tibia and basitarsus of hind leg 3.00, 5.75 and 5.00x their width, respectively; coxa smooth; length of hind tibial spurs 0.25 and 0.30x hind basitarsus. Wings. Fore wing: r:3-SR:SRl = 9.00:17.00:43.00; SR1, r, 1-SR+M in line. Hind wing: M+CU:1-M:1r-m = 10.00:32.00:16.00. Metasoma. LT1/WT1 = 0.68, first tergite largely smooth, with two sub-converging dorso-lateral carinaee, with few striae on lateral side; second tergite shining, with a smooth elongate median area bordered laterally by a groove largely crenulate to irregularly rugose, lateral to this the tergite is coarsely longitudinally and irregularly rugose; second suture deep with a narrow median break; third tergite densely and more or less evenly covered with short pale setae, with shallow puncture at base of setae, smooth and shiny between the punctures; 4th and 5th tergites hidden; ovipositor with a pre-apical dorsal notch; length of ovipositor sheath 0.10x fore wing, acute apically. Color. Yellow-brown to orange-brown. Flagellum, scapus laterally, tips of mandibles, apex of telotarsi, ovipositor sheath black; wings infuscate but lighter to their base.

VARIATIONS — The female paratype is similar in color, body length and number of antennal segments. The male paratypes are similar in color, body length, but have 32 antennal segments, the flagellum lightening toward apex, the second tergite shorter than in female, the longitudinal and irregular rugae on second tergite stronger, the second suture widened apically, third and fourth tergites strongly rugose.

ETYMOLOGY — The name reflects the unexpected discovery of a third species in this genus.
