Type material. — THAILAND: Holotype ♀, Thailand, Chiang Mai, Huai, Nam Dang NP, visitor center, 19.313 ° N, 98.607 ° E, pan trap, 25-26.IV.2008, Anuchart & Thawatchai , H2852, Pristaulacus perfidus Turrisi & Smith sp. nov. ♀, 2018, Holotypus ” ( QSBG) GoogleMaps .
Etymology. — The name is derived from the Latin adjective perfidus (treacherous), based on an impression from the aspect of the wasp.
Diagnosis.—Medium-sized species, body length: 10.1 mm (excluding ovipositor); colour mostly black; A1 dark reddish ventrally legs extensively dark brown to light brown; wings hyaline; forewing with a small irregular brown spot on middle of cell B, and wide subquadrate substigmal brown spot sides of metasomal tergites and sternites dark brown. Setae: goldish on mandible, brownish on vertex and temple, whitish otherwise; head subquadrate, temple moderately developed, rounded, slightly convergent posteriorly; occipital margin almost straight, only very weakly concave medially; occipital carina narrow, about 0.3 X diameter of ocellus; mesosoma coarsely sculptured, transversecarinate to areolate-rugose; lateroventral margin of pronotum with one anterior long, acute, forwarded tooth-like process; anterior margin of mesoscutum squared, very slightly overhanging pronotum; fore wing with vein 2-rs+m short; coxa III transverse-carinate dorsally, transverse-carinulate to polished punctate ventrally; tarsal claw pectinate with four tooth-like processes; metasoma pyriform (lateral view) fairly compressed; petiole elongate, very slender, 3.9 X longer than wide; ovipositor 1.4 X fore wing length.
Description. — Female (holotype): Length: 10.1 mm; antenna length: 5.8 mm; forewing length: 7.4 mm; ovipositor length: 10.8 mm. Colour: Black, except: mandible extensively dark reddish; A1 dark reddish ventrally trochanters, femurs, and hind tibia dark brown; fore and mid tibiae, and tarsi light brownish to brownish (except pretarsi); wings hyaline; forewing with a small irregular brown spot on middle of cell B, and wide subquadrate substigmal brown spot; metasoma with sides of tergites and sternites dark brown. Setae: goldish on mandible, brownish on vertex and temple, whitish on frons, clypeus and otherwise. Head: From above, 1.1 X wider than long, shiny; occipital margin almost straight, only very weakly concave medially; temple, from above, moderately developed, rounded, slightly convergent posteriorly, 0.6 X eye length; occipital carina narrow, about 0.3 X diameter of ocellus; POL:OOL: 1.3; ocellar area 2.2 X wider than long; vertex with fine, superficial and moderately dense punctures (distance between punctures 3.0–4.0 X puncture diameters); frons with moderately coarse, deep and dense punctures (distance between punctures 1.5–2.0 X puncture diameters); clypeus with moderately coarse, deep and dense punctures (distance between punctures 1.5–2.0 X puncture diameters); temple with fine to moderately coarse, deep and moderately dense to dense punctures (distance between punctures 1.0–4.0 X puncture diameters); malar area with coarse, deep and very dense punctures (distance between punctures 0.5–1.0 X puncture diameters); antenna 0.8 X forewing length; A3 5.0 X longer than wide; A4 9.0 X longer than wide and 1.8 X than A3; A5 8.3 X longer than wide and 1.7 X than A4. Setae: erect, short and moderately dense on vertex and upper frons; recumbent, long and dense on lower frons and clypeus; semierect, moderately long and moderately dense on temple (length of setae 0.8 X diameter of ocellus); recumbent, short and dense on malar area. Mesosoma: Coarsely sculptured; pronotum areolate-rugose with one anterior long, acute, forwarded tooth-like process on lateroventral margin; propleuron polished and shiny with fine, superficial and scattered punctures (distance between punctures 3.0–4.0 X puncture diameters); prescutum triangular, narrow, long, sharply incavate, transverse-carinate; mesoscutum transverse-carinate anterior to notauli (bearing 7 carinae), sharply distinct dorsally, anterior margin squared very slightly overhanging pronotum, otherwise areolate-rugose; notauli very wide and deep scutellum mostly transverse-carinate to longitudinal-carinate (on sides) except a narrow anterotransverse area areolate-rugose; mesopleuron areolate-rugose except anterior half of mesepimeron densely and coarsely punctate; metanotum areolaterugose; propodeum areolate-rugose; ventral parts of mesosoma mostly areolate-rugose; fore wing with vein 2-rs+m short; coxa I mostly polished punctate, except base slightly transverse-carinulate; coxa II mostly transverse-carinate, ventral parts partly polished punctate; coxa III transverse-carinate dorsally, transversecarinulate to polished punctate ventrally, punctures coarse, deep and dense (distance between punctures 1.0-2.0 X puncture diameters); inner spur of mid and hind tibiae fairly longer than outer spur; hind basitarsus 10.2 X longer than wide, and 1.0 X as tarsomeres 2-5; tarsal claw pectinate with four tooth-like processes. Setae: erect, moderately long and scattered on dorsal surface; semierect to recumbent, moderately long to long and dense on lateral and ventral parts, longer and denser on anterior margin of pronotum; erect, long and moderately dense on hind surface of propodeum; erect, moderately long and dense on propleuron (length of setae 0.6-0.7 X pretarsus length). Metasoma: Pyriform (lateral view) fairly compressed; petiole elongate, very slender, 3.9 X longer than wide; metasomal segment 1 polished impunctate; remaining segments polished punctate, punctures fine, superficial and very dense; ovipositor 1.4 X fore wing length. Setae: metasomal segment 1 and sides of sternites glabrous; otherwise recumbent, very short and dense.
Male: Unknown.
Distribution. — Thailand (Chiang Mai Province). Known only from type locality. Biology. — Unknown.
Remarks.—This species is not obviously related to any known species. It is mainly distinguished by the combination of the colour pattern along with shape of head and length of ovipositor.
