Type material. THAILAND: holotype ♀, “ Thailand, Ubon Ratchathani, Pha Taem, NP Huay, Pok waterfall, 15°37.321'N, 105°36.982'E, 419 m, Malaise trap, 18–25.IV.2007, Bunlu Sapsiri leg. T2171/ Pristaulacus sharkeyi Turrisi & Smith sp. n. ♀, 2009, Holotypus ” ( QSBG) .

Etymology. Named after Prof. Michael J. Sharkey (Department of Entomology, University of Kentucky, U.S.A.), specialist in parasitoid Hymenoptera and coordinator of the Tiger project, in acknowledgement for the valuable aulacid material made available to us for study.

Description. FEMALE (holotype). Length: 10.3 mm; fore wing length: 7.5 mm; ovipositor length: 8.5 mm.

Colour black, except: apical half of clypeus dark reddish orange; basal half of mandible dark reddish orange; maxillo-labial complex dark brown; antenna dark brown except A1 reddish orange; fore and mid legs (except mid coxa) reddish orange; hind tarsus dark brown; fore wing hyaline with a moderately wide brown spot below stigma (about half as stigma length and extended posteriorly slightly beyond 2-Rs) and apex widely infuscate; hind wing hyaline; metasoma blackish with sides of T1–T5 reddish orange. Setae: whitish.

Head, from above 1.2 × wider than long, shiny; occipital margin with a moderately wide and deep medial groove; temple, from above, weakly developed, rounded, about half as eye length; occipital carina narrow, 0.3 × diameter of an ocellus absent along medial groove; POL:OOL= 1.6; ocellar area 2.2 × wider than long; vertex with fine, deep and scattered punctures (distance between punctures 4.0–5.0 × or more puncture diameters); temple with coarse, deep and dense punctures (distance between punctures 2.0 × puncture diameters); 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 mostly missing, present only basally); A3 5.3 × longer than wide; A4 9.0 × longer than wide, and 2.0 × longer than A3; A5 8.5 × longer than wide, and 1.7 × longer than A3. Setae: semi erect, short and scattered on vertex; semi erect, short and dense on temple (length of setae 0.5–0.6 × diameter of an ocellus); erect, short and dense on upper frons; recumbent, moderately long and dense on lower frons, clypeus and malar area.

Mesosoma coarsely sculptured; pronotum areolate-rugose, with one very 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, deep and dense to dense (basally) on ventral surface (distance between punctures 1.0– 2.0 × puncture diameters, mostly 2.0 ×); prescutum triangular, narrow, long, very weakly concave, transverse carinate; mesoscutum mostly transverse-carinate, areolate-rugose on posterolateral corners; anterior margin not prominent, rounded (lateral view); notauli superficial and wide, slightly evident; scutellum transverse-carinate, areolaterugose on posterolateral corners; mesopleuron areolate-rugose, foveolate and areolate-rugose on subalar area; metanotum longitudinally carinate, except middle, areolate-rugulose; propodeum areolate-rugose, except 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 punctate, with fine, superficial and scattered punctures; coxa II and III entirely transverse-carinate; spurs of mid and hind tibia subequal in length; hind basitarsus 11.2 × longer than wide, and 1.2 × as tarsomeres 2–5; tarsal claw with four tooth-like processes. Setae: erect, very short and moderately dense to dense on dorsal surface; recumbent, 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, 3.9 × longer than wide; segments 1 and 2 polished and shiny, impunctate; remaining tergites with a weak and fine microsculpture and fine, superficial and dense punctures, except laterally; sternites with fine, superficial and scattered punctures; S7 polished, with coarse, deep and dense punctures; T8 very finely microreticulate, with fine (not well defined), superficial and moderately dense punctures; ovipositor 1.1 × fore wing length. Setae: segments 1–2 and S3 glabrous; recumbent, short and scattered to dense on T3, T4 and S4–S6, except sides; recumbent to semi erect, short and dense on remaining tergites and sternites, except sides.

MALE unknown.
