Diagnosis. This species is similar to P. insignis ( Vander Linden, 1829)  in having the following: clypeus slightly convex medially, with sparse, fine punctures, slightly coriaceous; free margin of clypeus broadly produced medially, truncate apically; interantennal tubercle narrow, short; middle and upper frons markedly coriaceous, with large, dense punctures; occipital carina usual, simple; scutal patches absent; notaulus shallowly grooved and crenulate, reaching one third of scutum; parapsidal line conspicuous; scutellum shiny with midsize, dense punctures; metanotum slightly coriaceous, with fine, dense punctures; hypersternaulus and episternal sulcus conspicuously crenate; omaulus absent; metasomal segments half mat, slightly coriaceous, with fine, dense punctures; sternum II deeply impressed basally.

It can be distinguished from P. insignis (Vander Linden)  by the following characters: scrobal sulcus deeply grooved, inconspicuously crenate; labrum not constricted subapically; ocellar triangle slightly convex, markedly coriaceous, with large, dense punctures; vertex behind ocelli with large, dense punctures; admedian line conspicuous; metapleuron slightly coriaceous; metasoma distinctly constricted between segments I and II; in female, mesopleuron coarsely coriaceous, with large, dense punctures; in male, flagellomeres I–VII beneath with broad tyloids; spinose tubercles absent on the hind margin of metasomal tergum VI mesally. In P. insignis (Vander Linden)  the scrobal sulcus slightly impressed; labrum distinctly constricted subapically; ocellar triangle nearly flat, slightly coriaceous, with midsize, dense punctures; vertex behind ocelli with midsize, dense punctures; admedian line slightly impressed; metapleuron shiny; metasoma slightly constricted between segments I and II; in female, mesopleuron slightly coriaceous, with fine to midsize, dense punctures; in male, flagellomeres II–VIII beneath with narrow tyloids; spinose tubercles present on the hind margin of metasomal tergum VI mesally.

Description. Female and male. Black; apical ⅓ of mandible reddish brown, remainder yellow; palpi, scape beneath and pronotal lobe yellow; tegula dark brown to black; outer margin of fore tibia, basal one fifth of hind tibia (rest of tibia dark brown) yellow, tarsi reddish to dark brown; petiole, and metasomal segments black, apical segment dark brown; setae on clypeus sparse and silvery ( Fig. 2View FIGURE 2 ad).

Mandible tridentate apically ( Fig. 2View FIGURE 2 ad). Labrum not constricted subapically ( Fig. 2View FIGURE 2 ad). Clypeus slightly convex medially, with sparse, fine punctures, slightly coriaceous. Lower frons markedly coriaceous, frontal median carina lacking. Middle and upper frons markedly coriaceous, with large, dense punctures. Ocellar triangle slightly convex, markedly coriaceous, with large, dense punctures. Vertex behind ocelli with large, dense punctures and dense, fine, transverse striation, markedly coriaceous ( Fig. 2bView FIGURE 2). Occipital carina usual, simple.

Pronotal collar without anterior carina, antero-lateral angle slightly produced. Mesoscutum coarsely coriaceous, with large, dense punctures that are 0–1 × diameters apart, with sparse, irregular, short, longitudinal rugae posteriorly, anterior slope vertical and high, nearly 2 × midocellar diameter; scutal patches absent; admedian line conspicu- ous, extending to ⅓ of scutum; notaulus shallowly grooved and crenulate, reaching one third of scutum; parapsidal line conspicuous, long ( Fig. 5bView FIGURE 5). Scutellum shiny with midsize, dense punctures that are 1–2 × diameters apart. Metanotum slightly coriaceous, with fine, dense punctures. Mesopleuron coarsely coriaceous, with large, dense punctures, posteriorly with short, sparse longitudinal rugae; scrobal sulcus deeply grooved, inconspicuously crenate; hypersternaulus and episternal sulcus conspicuously crenate; omaulus absent ( Fig. 6bView FIGURE 6). Metapleuron slightly coriaceous. Propodeal enclosure not delimited by carina, with conspicuous, dense, longitudinal rugae, mixed with well-defined, short, transverse rugae medially; posterior surface with irregular rugae ( Fig. 5fView FIGURE 5); lateral surface with dense, fine, oblique, longitudinal rugae anteriorly, and conspicuous reticulation posteriorly.

Petiole short, nearly 1 × as long as midocellar diameter ( Fig. 2cView FIGURE 2); metasomal segments half mat, slightly coriaceous, with fine, dense punctures; sternum II deeply impressed basally; metasoma distinctly constricted between segments I and II ( Fig. 6fView FIGURE 6).

Female. Body length 4.7– 6 mm; labrum ivory to yellowish, pedicel, and flagellum black; forewing veins dark brown; midtibia, and midtarsus dark brown; free margin of clypeus broadly produced medially, truncate apically ( Fig. 2aView FIGURE 2); interantennal tubercle narrow, short ( Fig. 2aView FIGURE 2); gena with large, dense punctures, coarsely coriaceous; HW: HLD: HLF = 83: 44: 77; HW: EWd: EW: TW: EL = 83: 17: 25: 27: 57; POD: OOD: OCD = 11: 14: 20; length of scape: length of pedicel: length of flagellomere I: width of flagellomere I: length of flagellomere II: width of flagellomere II = 28: 8: 7: 6: 7: 6; PL: PW: LTI: WTI = 6: 11: 53: 51; sternum I with a conspicuous longitudinal keel medially, extending from anterior o posterior margin ( Fig. 6fView FIGURE 6).

Male. Body length 4.9 mm; labrum, pedicel, and flagellum dark brown; forewing veins brown; midtibia, and midtarsus reddish brown; free margin of clypeus slightly produced medially, nearly arcuate apically ( Fig. 2dView FIGURE 2); lower frons without frontal median carina, interantennal tubercle inconspicuous; gena with fine to midsize dense punctures, coarsely coriaceous; HW: HLD: HLF = 69: 33: 58; HW: EWd: EW: TW: EL = 69: 16: 21: 19: 44; POD: OOD: OCD = 10: 13: 13; length of scape: length of pedicel: length of flagellomere I: width of flagellomere I: length of flagellomere II: width of flagellomere II = 15: 5: 6: 6: 7: 7. Flagellomeres I–VII beneath with black broad tyloids ( Fig. 2eView FIGURE 2); PL: PW: LTI: WTI = 6: 11: 45: 42; sternum I with a slender longitudinal keel medially, reaching middle of sternum I; spinose tubercles absent on the hind margin of metasomal tergum VI mesally. Genitalia ( Fig. 2View FIGURE 2 f–h).

Distribution. China (Xinjiang).

Etymology. The name, profundesulcatus  , is derived from the Latin stem profunde- (= deeply) and sulcatus (= sulcate), referring to the scrobal sulcus deeply grooved and inconspicuously crenate, which is one of the main recognition characters of this species.
