Diagnosis.
This species can be distinguished from the similar species P. bisulcatus Bashir & Ma, 2019 and other congeners by: occipital carina not crenate; labrum not constricted subapically; anterior part of scutum nearly right angle, significantly higher than pronotum; scutum smooth, without rugae posteriorly; propodeal enclosure with irregular rugae medially, and with sparse, oblique rugae on each side. Passaloecus bisulcatus has the following characters: occipital carina distinctly crenate; labrum distinctly constricted subapically; anterior part of scutum normal; scutum with sparse, short, longitudinal rugae posteriorly; propodeal enclosure with sturdy, irregular reticulation.
Description.
Female. Measurements. ♀, BL: 5.3 mm; HLF: HW: HLD = 53: 54: 36; HW: EWd: EW: TW: EL = 54: 13: 15: 25: 40; POD: OOD: OCD = 8: 9: 12; SL: PL: LFI: LFII: WFI: WFII = 20: 6: 6: 6: 3: 3; WAS: AOD: IAD = 4: 5: 6; EDU: EDL = 32: 22; PLL: PW: LTI: WTI = 6: 10: 38: 36.
Color pattern. Body black; mandible predominantly reddish-brown, basal inner margin grayish-white; palpi and tegula brown to dark brown; scape ventrally and pronotal lobe ivory; fore and mid tibiae and tarsis brown to dark brown; hind leg: tibia brown, except basal 1 / 4 ivory, tarsus brown; sides of lower frons and clypeus with scattered, silvery, short setae; outer margin of mandible with several golden, long setae.
Head. Mandible bidentate apically, inner tooth large (Fig. 2 A View Figure 2 ). Labrum heart-shaped, not constricted subapically. Clypeus conspicuously convex medially, coriaceous; free margin of clypeus broadly produced, truncate medially; sides of lower frons coarsely coriaceous (Fig. 2 A View Figure 2 ). Scapal hollow coriaceous, shallow, not clearly defined (Fig. 2 A View Figure 2 ). Interantennal tubercle narrow and short; frontal median carina slightly impressed; median and upper frons coarsely coriaceous, slightly convex, with dense, midsize punctures (Fig. 2 A View Figure 2 ). Ocellar triangle shiny, moderately convex, with dense, midsize punctures (Fig. 2 B View Figure 2 ). Vertex shiny, coriaceous, with dense, weakly transverse striations (Fig. 2 B View Figure 2 ). Gena shiny, coriaceous and impunctate. Occipital carina narrow, not crenate (Fig. 2 B View Figure 2 ). Inner and outer orbital furrows lacking (Fig. 2 A View Figure 2 ).
Mesosoma. Pronotal collar with robust, anterior, transverse carina, antero-lateral corner absent (Fig. 2 C View Figure 2 ). Scutum shiny, with dense, midsize to large punctures, anterior area nearly right angle, significantly higher than pronotum and with sparse, transverse striations; scutal patches nearly ovate, slightly raised; admedian line weakly impressed, extending to 2 / 7 of scutum length; notaulus distinct and crenulate, slightly longer than admedian line; parapsidal line distinct, long (Fig. 2 C View Figure 2 ). Scutellum shiny, with dense, fine punctures. Metanotum shiny and smooth (Fig. 2 C View Figure 2 ). Mesopleuron shiny, with sparse, midsize punctures, posterior area with contiguous, very short, longitudinal rugae; scrobal suture narrow, shallowly impressed and weakly crenate; hypersternaulus and episternal sulcus deep, conspicuously crenate; omaulus absent (Fig. 2 D View Figure 2 ). Metapleuron shiny and smooth (Fig. 2 D View Figure 2 ). Propodeal enclosure matte, not delimited by carina, with irregular rugae medially, and irregular, sparse, oblique rugae laterally, area between rugae with contiguous, fine punctures; posterior surface of propodeum coarsely coriaceous, shiny, and with reticulation posteriorly (Fig. 2 E View Figure 2 ); lateral surface of propodeum with dense, slender, oblique rugae anteriorly, and irregular reticulation posteriorly (Fig. 2 D View Figure 2 ).
Metasoma. Petiole short, not longer than width (Fig. 2 F View Figure 2 ); dorsal surface of petiole with median, longitudinal groove (Fig. 2 F View Figure 2 ); lateral surface of petiole with two short, longitudinal carinae (Fig. 2 G View Figure 2 ). Gaster shiny, with sparse, tiny punctures; sternum I matte, with several, longitudinal rugae, median, longitudinal carina lacking; sternum II deeply impressed basally; gaster distinctly constricted between terga I and II (Fig. 2 G View Figure 2 ); pygidial plate lacking.
Male. Unknown.
Distribution.
China (Xinjiang).
Etymology.
The name clypeconvexus is derived from the Latin clype - (= clypeus) and the Latin word convexus (= convex), referring to the clypeus conspicuously convex medially.
