Type material.

Holotype, ♂ (CNC), "Aust[ralia]: Qld., Mt. Glorious N.P., 630 m, 28.ii.1984, L. Masner s.s.".

Diagnosis.

Antenna of ♀ unknown, of ♂ with 30 segments, cylindrical and slender, dark brown but scapus and pedicellus brownish yellow ventrally; palpi pale yellowish; with transverse space between clypeus and closed mandibles (Fig. 52); head moderately enlarged behind eyes in dorsal view (Fig. 53); length of malar space 0.9 times basal width of mandible (Fig. 52); mesosoma of ♀ normal, with mesoscutum far above upper level of pronotum (Fig. 47); pronotum and mesoscutum yellowish brown; propodeum mainly punctate medially (Fig. 49); fore and middle legs (but tibiae and tarsi darkened) brownish yellow, and hind leg dark brown; length of setose part of ovipositor sheath unknown.

Description.

Holotype, ♂, length of fore wing 2.8 mm, and of body 3.5 mm.

Head. Antenna with 30 segments, pedicellus short (Figs 51, 54), length of third segment 1.2 times fourth segment, third, fourth and penultimate segments 2.9, 2.4 and 2.7 times as long as wide, respectively (Fig. 51) and with apical segments sessile, medially parallel-sided and apically slightly narrowed (Fig. 51); length of maxillary palp 1.1 times height of head; occipital carina complete, comparatively low dorsally (Fig. 54), strongly curved ventrally and joining hypostomal carina far below mandible and occipital flange curved and elongate; eye 1.1 times as long as temple in dorsal view; temples slightly narrowed behind eyes; OOL:diameter of posterior ocellus:POL = 6:5:8; vertex and frons smooth (but vertex with some punctures) and moderately shiny, with some long setae, convex, frons without median groove, and anteriorly flattened; face sparsely coarsely punctate and with some superficial rugae (Fig. 52); clypeus flattened and smooth ventrally, with medially weakly protruding thick ventral rim (resulting in steep ventral area), dorsally weakly convex and with few coarse punctures; with medium-sized transverse space between closed mandibles and clypeus; length of malar space 0.9 times basal width of mandible; mandible slightly convex medially and with few punctures, both apical teeth large.

Mesosoma. Length of mesosoma 1.7 times its height; dorsal pronope and antescutal depression absent; side of pronotum antero-medially and posteriorly coarsely crenulate, rugose, antero-ventrally rugose and remainder largely smooth; mesopleuron coarsely punctate dorsally; precoxal sulcus complete, wide medially and coarsely punctate (Fig. 47); remainder of mesopleuron smooth; mesosternal suture rather narrow and finely crenulate; postpectal carina complete medio-ventrally, curved; notauli complete, anteriorly moderately crenulate and posteriorly ending in wide rugose area (Fig. 48); remainder of mesoscutum slightly convex, strongly shiny, and largely smooth, except for some fine punctures (Fig. 48), mesoscutum sparsely setose laterally and moderately setose medially; scutellar sulcus with six costae; scutellum slightly convex, smooth (except for some setiferous punctures) and shiny; metapleuron entirely coarsely punctate; propodeum coarsely punctate, only anteriorly partly sparsely punctate (Figs 48, 49), its median carina absent, its posterior face medially rather differentiated and without tubercle postero-laterally (Fig. 47).

Wings. Fore wing: pterostigma wide (Fig. 46); 1-M slightly curved; 1-SR short (Fig. 46); marginal cell closed anteriorly; 1-R1 1.3 times longer than pterostigma and direct after pterostigma weakly pigmented (as apex of pterostigma: Fig. 46); vein r emitted far after middle of pterostigma; r:3-SR:SR1 = 5:6:53; vein SR1 straight; 2-SR:3-SR:r-m = 19:6:11; 2-M much longer than 3-SR; m-cu interstitial; 1-CU1 oblique and narrow, about as long as cu-a; 1-CU1:2-CU1 = 1:8; basal and subbasal cells of fore wing similarly setose as other cells. Hind wing: marginal cell parallel-sided apically, but hardly visible; M+CU:1-M:1r-m = 27:13:10; basal and subbasal cells less densely setose than other cells.

Legs. Hind coxa largely transversely striate but basally punctate (Figs 49, 50); tarsal claws with wide truncate lamelliform lobe (Fig. 55); length of femur, tibia and basitarsus of hind leg 4.3, 8.4 and 6.8 times as long as their maximum width; fore femur moderately widened and ventrally convex, 4.0 times longer than wide and apically rounded (Fig. 55); fore and middle tarsi slender and subcylindrical (Figs 45, 55); hind tibia distinctly striate.

Metasoma. First tergite 2.8 times longer than its apical width, petiolate basally and gradually widened apically (Fig. 49), coarsely striate, dorsal carinae unite to form a median carina (Fig. 49), basal half of tergite closed ventrally and sternite distinctly differentiated; laterope absent; second tergite smooth.

Colour. Black; scapus and pedicellus ventrally, clypeus, mandible, fore and middle legs (but tibiae and tarsi darkened) brownish yellow; palpi and tegulae pale yellow; face, pronotum, mesoscutum, mesosternum and mesopleuron antero-dorsally and ventrally yellowish brown; remainder of antenna and of mesosoma, first metasomal tergite, hind leg, pterostigma (but apex pale), most veins of fore wing dark brown; remainder of metasoma brown, but ventrally membranes whitish; wing membrane subhyaline.

Etymology.

Named after its punctate propodeum ( “punctus” is puncture in Latin).

Distribution.

Australia (Queensland). Collected in February.
