Type material. THAILAND: holotype Ƥ labelled “Khao Kho, 8–900 m, Petchabun [Phetchabun Province], N. Thai., 24-27.V.2009, Takakuwa, M. leg./ Pristaulacus takakuwai Turrisi & Watanabe sp.n. Ƥ 2010 Holotypus ” (UCCT).
Etymology. Named after Dr Masatoshi Takakuwa (Kanagawa Prefectural Museum of Natural History, Japan), who collected the holotype.
Description (holotype, Ƥ). Length: 14.7 mm; antenna length: 8.4 mm; fore wing length: 12.1 mm; ovipositor length: 10.7 mm.
Colour black, except: clypeus yellowish orange; mandible extensively yellowish orange, except teeth; maxillolabial complex dark reddish orange with palpomeres reddish orange; A1–2 reddish orange; fore and mid legs extensively orange (except base of mid coxa black and pretarsi dark brown); hind tarsus (except pretarsus) black brown; wings hyaline, yellowish, with veins black to brown; fore wing with irregular and wide dark brown spot below stigma (about wide as two-thirds of stigma length); metasoma extensively dark orange except T1 and middle of other tergites (except T2). Setae golden.
Head, from above, 1.2× wider than long, shiny; occipital margin weakly concave; temple, from above, well developed, straight to weakly convex, about 0.8× as long as eye length; occipital carina narrow, 0.1–0.2× diameter of an ocellus; POL:OOL= 1.1; vertex with fine, deep and dense punctures (distance between punctures 1.0–3.0× puncture diameter); temple with fine to coarse, deep and dense punctures (distance between punctures 1.0–2.0× puncture diameter); upper half of frons with fine, deep and dense punctures (distance between punctures about 1.0– 1.5× puncture diameter); lower half of frons with coarse, deep and dense punctures (distance between punctures 0.5× puncture diameter); clypeus with coarse, deep and dense punctures (distance between punctures 0.5× puncture diameter); anterior half of malar area with fine, deep and dense punctures, posterior half with fine, deep and dense punctures; occipital area with fine, superficial and dense punctures; antenna 0.7× fore wing length; A3 1.9× longer than wide; A4 5.2× longer than wide, and slightly longer than A3; A5 7.1× longer than wide, and 1.5× longer than A3. Setae erect, long and dense on vertex; recumbent and semi erect to erect, long and very dense on temple (length of setae 0.8–0.9× diameter of an ocellus); semi erect to erect, long and dense on upper frons; recumbent, long and dense on lower frons and clypeus; recumbent, moderately long and very dense on dorsal half of malar area, less dense on remaining surface.
Mesosoma coarsely sculptured; pronotum areolate-rugose, foveolate above lateroventral margin, with one well-developed acute tooth-like process on each lateroventral margin, above side of propleuron; propleuron polished and shiny with coarse, deep and scattered to dense punctures on dorsal surface, fine, deep and dense punctures on ventral surface (distance between punctures about 2.0–4.0× puncture diameter); prescutum triangular, narrow, concave toward mesoscutum, transverse-carinulate; mesoscutum mostly areolate-rugose, transverse carinate on anterior lobe; anterior margin slightly prominent and weakly angulate (lateral view); notauli deep and wide; scutellum mostly transverse-carinulate-punctate, polished to weakly rugulose-foveolate on posterolateral corners; mesopleuron areolate-rugose to oblique-carinulate except a moderately wide part of subalar area polished-punctate; metanotum scrobiculate; propodeum coarsely areolate-rugose, anterior margin longitudinally carinate; ventral parts of mesosoma polished to transverse carinulate-foveolate, scrobiculate in middle; fore wing with vein 2–rs+m short; coxa I polished-punctate with fine, deep and dense punctures on ventral surface; coxa II transverse-carinate on dorsal surface, rugulose-punctate (on basal third) to transverse-carinulate on ventral surface; coxa III transversecarinate on dorsal surface, mostly polished-punctate on ventral surface, with fine, deep and dense punctures (distance between punctures 2.0–3.0× puncture diameter), except along inner margin, with coarse, deep and dense punctures (distance between punctures 0.2–1.0× puncture diameter); inner spur of mid and hind tibiae longer than outer spur; hind basitarsus 10.7× longer than wide, and 1.2× as tarsomeres 2–5; tarsal claw with four tooth-like processes. Setae erect to semi erect, short and dense on dorsal mesoscutum; recumbent to erect (on upper pronotum), long (on pronotum) and dense (on pronotum) on sides and venter of mesosoma; erect, long and dense on hind surface of propodeum; erect, long and dense on propleuron (setae length 0.8× pretarsus length).
Metasoma pyriform (lateral view), compressed laterally; petiole elongate, slender, 3.4× longer than wide; segment 1 polished with a few sparse punctures on T1; following segments with fine, superficial and dense punctures; S7 polished with coarse, deep and dense punctures; T8 microsculptured with fine, superficial and dense punctures; ovipositor 0.9× longer than fore wing length. Setae on segment 1 glabrous; recumbent, short and dense on T2; recumbent, short and dense on remaining segments; semi erect, long and dense on S7.

Remarks. This species is not obviously allied to any other described Oriental Pristaulacus (see Smith 2001; Turrisi et al. 2009; Turrisi & Smith 2011) and is easily recognized by the combination of the following characters: setae of the body entirely golden; wings hyaline, yellowish with apex infuscate; metasoma extensively reddish orange; shape of the head, with temple straight (dorsal view) (Fig. 19); ovipositor 0.9× fore wing length.
It superficially resembles P. rufobalteatus (Cameron 1907) described from Sikkim, India (Cameron 1907) (type material examined in BMHN) but it is easily distinguished from P. rufobalteatus by the colour pattern (Figs 18–27), with setae golden vs. whitish in P. rufobalteatus, wings hyaline, yellowish with apex infuscate vs. hyaline, not yellowish with apex not infuscate in P. rufobalteatus, hind legs mostly black to dark brown vs. reddish orange in P. rufobalteatus, the shape of the head, with temple more developed, straight in dorsal view (Fig. 19), vs. temple moderately developed, convex in P. rufobalteatus; the shape of the basal antennomeres, quite stout, with A3 1.9× longer than wide; A4 5.2× longer than wide, and slightly longer than A3; A5 7.1× longer than wide, and 1.5× longer than A3, vs. slender with A3 5.6× longer than wide; A4 12.0× longer than wide, and 1.9× longer than A3; A5 11.1× longer than wide, and 1.6× longer than A 3 in P. rufobalteatus; shorter petiole, 3.4× longer than wide (Fig. 27), vs. 4.2× in P. rufobalteatus; and shorter ovipositor, 0.9× fore wing length vs. 1.4× in P. rufobalteatus.
Distribution. Thailand (Phetchabun Province), known only from type locality.
Biology. Unknown.
