Type material.
Holotype: China • ♀; Yunnan, Shangri-La City, Pudacuo National Park ; 27°55'13"N, 99°52'46"E; 3515 m elev.; 16. VII. 2022; coll. Zhizhi Liu; sweep net ( YNAU) GoogleMaps . Paratype: China • 1 ♀; Shaanxi, Baoji City, Tiantai Mountain Scenic Area ; 34°17'10"N, 107°10'55"E; 852 m elev.; 8–10. VI. 1998; NO. 983654; coll. Yun Ma; sweep net ( YNAU) GoogleMaps .
Diagnosis.
This species differs from the similar species P. labrinigratus Ma & Li, 2012 and other congeners in the following characteristics: free margin of clypeus with two robust, triangular teeth medially, distinctly reflected, area between two teeth deeply concave; scutal patches absent; scutum with sparse, irregular, short, longitudinal rugae posteriorly; scapal hollow coriaceous, shiny and clearly defined; gaster not constricted between terga I and II. Passaloecus labrinigratus has the following characters: free margin of clypeus broadly produced, truncate medially; scutal patches ovate; scutum smooth, without rugae posteriorly; scapal hollow coarsely coriaceous, moderately matte, not clearly defined; gaster slightly constricted between terga I and II.

Color pattern. Body black; mandible inner margin pale yellow, remainder reddish-brown to dark brown; labrum ivory medially, central part dark brown; ventral scape ivory to pale yellow; tegula, palpi and forewing veins dark brown; fore tibia and tarsus dark brown; mid leg: inner margin of femur, tibia, and tarsus pale yellow to yellowish-brown, remainder of femur and trochanter dark brown; basal 1 / 4 of hind tibia dark brown; clypeus with scattered, silvery, short setae.
Head. Mandible bidentate apically, inner tooth large (Fig. 1 A View Figure 1 ). Labrum slightly narrower than clypeal lobe, V-shaped, apex bluntly rounded, slightly constricted subapically (Fig. 1 A View Figure 1 ). Clypeus flat, with sparse, fine punctures, slightly coriaceous; free margin of clypeus with two robust, triangular teeth medially, distinctly reflected, area between two teeth deeply concave (Fig. 1 A View Figure 1 ). Sides of lower frons slightly coriaceous; scapal hollow coriaceous, shallow, clearly defined; interantennal tubercle very short; frontal median carina absent; median and upper frons distinctly coriaceous, with dense, large punctures, sometimes contiguous (Fig. 1 A View Figure 1 ). Ocellar triangle coarsely coriaceous, slightly convex, and with dense, midsize punctures (Fig. 1 B View Figure 1 ). Vertex distinctly coriaceous, with dense, midsize punctures and weakly transverse striations (Fig. 1 B View Figure 1 ). Dorsal gena coarsely coriaceous, with dense, fine to midsize punctures; ventral gena coarsely coriaceous, with midsize punctures. Occipital carina narrow, not crenate (Fig. 1 B View Figure 1 ). Inner and outer orbital furrows lacking (Fig. 1 A View Figure 1 ).
Mesosoma. Pronotal collar with robust, anterior, transverse carina, antero-lateral corner slightly produced (Fig. 1 C View Figure 1 ). Scutum coarsely coriaceous, with dense, midsize punctures, anterior area nearly right angle, significantly higher than pronotum, posterior area with sparse, irregular, short, longitudinal rugae; scutal patches absent; admedian line distinctly impressed, extending to 1 / 3 of scutum length; notaulus shallowly impressed, indistinctly crenulate, extending to 1 / 3 of scutum length; parapsidal line distinct, longer than admedian line (Fig. 1 C View Figure 1 ). Scutellum slightly coriaceous, with dense, midsize punctures (Fig. 1 C View Figure 1 ). Metanotum slightly coriaceous, with dense, fine punctures (Fig. 1 C View Figure 1 ). Mesopleuron coarsely coriaceous, with dense, midsize punctures, posterior area with sparse, very short, longitudinal rugae; scrobal suture deeply impressed, not crenate; hypersternaulus and episternal sulcus distinctly crenate; omaulus absent (Fig. 1 D View Figure 1 ). Metapleuron shiny and smooth (Fig. 1 D View Figure 1 ). Propodeal enclosure not delimited by carina, with irregular rugae medially, and several, robust oblique rugae laterally; posterior surface of propodeum with irregular rugae, interspersed with several, robust, transverse rugae (Fig. 1 E View Figure 1 ); lateral surface of propodeum with dense, slender, irregular, oblique rugae anteriorly, and sparse, robust, oblique rugae posteriorly (Fig. 1 D View Figure 1 ).
Metasoma. Petiole short, not longer than width; dorsal surface of petiole with median, longitudinal groove (Fig. 1 F View Figure 1 ); lateral surface of petiole with two short, longitudinal carinae (Fig. 1 G View Figure 1 ). Gaster moderately matte, slightly coriaceous, with dense, fine punctures (Fig. 1 G View Figure 1 ); sternum I with several, longitudinal rugae; median, longitudinal carina lacking; sternum II deeply impressed basally; gaster not constricted between terga I and II (Fig. 1 G View Figure 1 ); pygidial plate lacking.
Male. Unknown.
Distribution.
China (Yunnan, Shaanxi).
Etymology.
The name clypearcuatus is derived from the Latin clype - (= clypeus) and the Latin word arcuatus (= arcuate), referring to the area between two teeth on free margin of clypeus with an arcuate, deep concavity.
