Etymology. Named after Dr John T. Jennings (University of Adelaide, Australia) for his contributions on the taxonomy and phylogeny of Aulacidae and Gasteruptiidae (Hymenoptera) .

Description. FEMALE (holotype). Length: 14.0 mm; fore wing length: 10.4 mm; ovipositor length: 11.0 mm.

Colour black except: maxillo-labial complex blackish; antenna dark brown; legs dark brown; fore wing largely infuscate, strongly on cells C, B and SB, less centrally, with a large dark brown spot below stigma (1.3 × stigma length and extended to vein Cu1a); hind wing slightly infuscate on proximal half moderately infuscate on distal half; metasoma with sides of T1 and T2 slightly lighter; valvula 3 of ovipositor dark brown. Setae: light brown, goldish on mandible, whitish on pronotum and propleuron.

Head, from above 1.2 × wider than long, moderately shiny; occipital margin strongly concave, with a wide and moderately deep medial groove; temple, from above, well developed, rounded longer than eye length; occipital carina narrow, 0.2 × or less diameter of an ocellus; POL:OOL= 1.2; ocellar area 2.1 × wider than long; vertex and temple with fine to coarse, deep and dense punctures (distance between punctures 2.0 × puncture diameters); frons with coarse, deep and dense punctures (distance between punctures 1.0 × or less puncture diameters); clypeus with coarse, superficial and dense punctures; malar area with coarse, deep and scattered punctures; occipital area with coarse, deep and scattered to dense punctures; antenna 0.6 × fore wing length; A3 3.4 × longer than wide; A4 3.9 × longer than wide, and 1.3 × longer than A3; A5 3.6 × longer than wide, and 1.2 × longer than A3. Setae: erect, long and dense on vertex; semi erect, long and scattered to dense on temple (length of setae 1.0–1.1 × diameter of an ocellus); semi erect to erect, long and dense on upper frons; recumbent, long and dense on lower frons and clypeus; recumbent, short and dense on malar area.

Mesosoma coarsely sculptured; pronotum densely and coarsely areolate-rugose, densely and coarsely foveolate above lateroventral margin, with two tooth-like processes on each lateroventral margin, anterior one moderately developed, posterior one weak and obtuse; propleuron polished and shiny with coarse, deep and dense punctures on dorsal surface, fine (laterally) to coarse, deep and dense on ventral surface (distance between punctures 1.0–2.0 × puncture diameters); prescutum triangular, wide, long, not concave to weakly concave toward apex, coarsely punctate on basal half, transverse-carinate on apical half; mesoscutum transverse-carinate to areolate rugose partly on anterior lobe and posterior to notauli; dorsally convex and slightly prominent; anterior margin slightly prominent and angulate (lateral view); notauli deep and wide; scutellum areolate-rugose; mesopleuron areolate-rugose, foveolate on subalar area; metanotum longitudinally carinate, except middle, areolate-rugose; propodeum coarsely areolate-rugose, except anterior margin longitudinally carinate; venter of mesosoma mostly polished, punctate very weakly confused-rugulose, transverse-carinate medially; fore wing with vein 2-rs+m short; coxa I polished and shiny, with coarse, superficial and scattered to dense punctures; coxa II transverse-carinate on dorsal surface, polished and punctate on ventral surface, with fine, deep and mostly scattered punctures, dense basally; coxa III transverse-carinate on dorsal surface, polished and punctate on ventral surface, punctures coarse, deep and dense (distance between punctures 1.0–2.0 × puncture diameters); inner spur of mid and hind tibia slightly longer than outer spur; hind basitarsus 7.7 × longer than wide, and 1.1 × as tarsomeres 2–5; tarsal claw with six tooth-like processes. Setae: erect to semi erect, short and dense on dorsal surface; erect to semi erect, long and dense on sides and venter of mesosoma; erect, long and dense on hind surface of propodeum; erect, long and dense on propleuron (setae length 0.7–0.8 × pretarsus length).

Metasoma pyriform (lateral view), strongly compressed laterally; petiole moderately elongate, slender, 2.5 × longer than wide; segments 1 and 2 mostly polished and shiny, with a few scattered fine and superficial punctures on hind half of T2; remaining tergites with fine, superficial and dense punctures; remaining sternites with less dense punctures except laterally; S7 polished-punctate, punctures coarse, deep and dense; T8 very finely microreticulate, with fine, superficial and dense punctures; ovipositor 1.1 × fore wing length. Setae: segments 1 and 2 glabrous; semi erect, very short and dense medially on S3; recumbent to semi erect, short and dense on remaining tergites and medially on sternites.

MALE unknown.
