Etymology. The name is derived from Thailand, a noun in apposition.

Description. FEMALE (holotype). Length: 11.8 mm; fore wing length: 8.4 mm; ovipositor length: 12.3 mm.

Colour black, except: clypeus with apical margin dark reddish; mandible reddish orange on proximal half, dark brown on distal half; maxillo-labial complex dark brown; antenna with A1 extensively dark reddish orange mainly on ventral surface; fore and mid legs reddish orange to dark reddish orange except coxae, hind tarsus dark brown; fore wing hyaline with a very small and irregular brown spot between cells SB and SD1, a wide subquadrate dark brown spot below stigma (slightly narrower than stigma extended posteriorly to vein 1Cua) and apex slightly infuscate; hind wing hyaline. Setae: whitish, slightly goldish on outer margin of mandible.

Head, from above 1.2 × wider than long, shiny; occipital margin with a wide and deep medial groove; temple, from above, moderately developed, rounded, about 0.6 × eye length; occipital carina moderately wide, 0.5 × diameter of an ocellus, absent along medial groove; POL:OOL= 1.4; ocellar area 2.0 × wider than long; vertex with fine, deep and scattered punctures (distance between punctures 4.0–5.0 × puncture diameters); temple with coarse, deep and dense punctures (distance between punctures 2.0 × puncture diameters), denser behind eye margin; frons with fine, deep and dense punctures (distance between punctures 2.0 × puncture diameters), denser above antennal insertion; clypeus with coarse, deep and dense punctures; malar area with fine, deep and dense punctures; antenna 1.0 × fore wing length; A3 4.7 × longer than wide; A4 12.9 × longer than wide, and 2.1 × longer than A3; A5 12.0 × longer than wide, and 1.9 × longer than A3. Setae: erect, short and scattered on vertex; semi erect, long and dense on temple (length of setae 0.8 × diameter of an ocellus); erect, short and dense on upper frons; recumbent, long and dense on lower frons, clypeus and malar area.

Mesosoma coarsely sculptured; pronotum mostly areolate-rugose, foveolate above lateroventral margin, with one well-developed acute and long anterior tooth-like process on each lateroventral margin; propleuron polished and shiny with coarse, deep and dense punctures on dorsal surface, fine to coarse (basally), deep and dense (basally) on ventral surface (distance between punctures 1.0–2.0 × puncture diameters); prescutum triangular, wide, long, not concave to very weakly concave toward apex, transverse carinate; mesoscutum mostly transversecarinate, areolate-rugose on posterolateral corners; anterior margin not prominent, rounded (lateral view); notauli deep and wide; scutellum transverse-carinate, areolate-rugose on posterolateral corners; mesopleuron areolaterugose, foveolate and areolate-rugose on subalar area; metanotum longitudinally carinate, except middle, areolaterugulose; propodeum areolate-rugose, except middle transverse-carinate and anterior margin longitudinally carinate; venter of mesosoma areolate-rugose laterally to polished submedially to transverse carinate medially; fore wing with vein 2-rs+m short; coxa I polished with fine, superficial and scattered punctures on medial half, coarse, deep and dense on outer half; coxa II transverse-carinulate-punctate dorsally, polished-punctate ventrally, with fine, superficial and dense puncture, except on base, with coarse, deep and dense punctures; coxa III weakly and irregularly transverse-carinulate with coarse, deep and scattered to dense punctures on dorsal surface, transverse-carinulate with coarse, deep and dense punctures on ventral surface (distance between punctures 1.0–2.0 × puncture diameters); spurs of mid tibia subequal in length; inner spur of hind tibia slightly longer than outer spur; hind basitarsus 12.2 × longer than wide, and 1.1 × as tarsomeres 2–5; tarsal claw with four tooth-like processes. Setae: erect to semi erect, short and dense on dorsal surface; recumbent to semi erect, long and dense on sides and venter of mesosoma (especially on pronotum); erect, long and dense on hind surface of propodeum; erect, long and dense on propleuron (setae length at most 0.8 × pretarsus length).

Metasoma pyriform (lateral view), strongly compressed laterally; petiole elongate, slender, 4.4 × longer than wide; segments 1 and 2 mostly polished and shiny, with a few scattered coarse and deep punctures medially on T1, T2; remaining tergites with a weak and fine microsculpture and fine, superficial and dense punctures, except laterally; sternites polished and impunctate; S7 polished with coarse, deep and dense punctures; T8 finely microreticulate, with fine to coarse, superficial and dense punctures; ovipositor 1.5 × longer than fore wing length. Setae: segments 1–2 and most remaining sternites (except S7) glabrous; recumbent, very short and dense on remaining tergites, except sides; semi erect, short and dense on S7.
