Type material.

Holotype: ♀, China: Guizhou: Dabanshui Forest Park, 26°32'N, 106°45'E, 10.VII.2011, No. 201503448, coll. Dongdong Feng (YNAU). Paratypes: 1♀ same as holotype except: No. 201503452; 1♀, China: Yunnan: Renhe County, 22°57'N, 104°17'E, 3.X.2016, No. 201605802 (YNAU); 1♀, China: Yunnan: Mengla County: Shangyong: Huiqingzhai, 21°23'N, 101°28'E, 21.V.2005, coll. Peng Wang (YNAU).

Diagnosis.

This species is similar to C. iwatai (Tsuneki, 1954) in sharing: labrum pentagonal, round toward apex; free margin of clypeal lobe truncate medially (Fig. 2a View Figure 2 ); inter-antennal tubercle as long as midocellus diameter (Fig. 2b View Figure 2 ); upper frons with fine puncture; ocellar triangle nearly flat, with fine punctures, sparsely distributed; occipital carina narrowed, not foveolate (Fig. 2b View Figure 2 ); inner and outer-orbital sulcus broad as flagellomere 1 length (Fig. 2a View Figure 2 ); admedian line conspicuous (Fig. 2h View Figure 2 ); notaulus shallowly foveolate; parapsidal line conspicuous (Fig. 2e View Figure 2 ); mesopleuron with fine punctures, sparsely distributed, hypersternaulus broadened as midtibial width, conspicuously foveolate, scrobal sulcus foveate, short as mid trochanter length (Fig. 2d View Figure 2 ); propodeum strongly irregular reticulated ridged on propodeal enclosure and side, reticulates broad as Fig. 2i View Figure 2 , with shiny interspace, propodeum with a smooth area posterodorsally; propodeum posterior surface with rectangular median groove, reticulate, a small smooth area medially, and irregular reticulation posteriorly (Fig. 2i View Figure 2 ); petiole side with few weak longitudinal carinae. Carinostigmus frontirugatus differs from C. iwatai by the following: clypeus moderately convex (Fig. 2a View Figure 2 ); inter-antennal tubercle distinctly broad at apex (Fig. 2b View Figure 2 ); median and lower frons rugose (Fig. 2a View Figure 2 ); upper frons longitudinal carina distinct, reaching anterior ocellus but weak (Fig. 2b View Figure 2 ); gena with dense, sturdy, oblique transverse rugae; lower gena with coarse punctures densely distributed; pronotal collar strongly elevated medially, lateral angles not so sharp as C. iwatai (Fig. 2e View Figure 2 ); scutum with several slender, transverse striations anteriorly (Fig. 2h View Figure 2 ); scutellum shiny; omaulus broadened as midtibial width (Fig. 2d View Figure 2 ); dorsal surface of petiole with dense weak longitudinal striations (Fig. 2c View Figure 2 ) and pygidial area punctate (Fig. 2g View Figure 2 ). Carinostigmus iwatai (Tsuneki) has following characters: clypeus slightly convex ( Tsuneki 1954: fig. 12); inter-antennal tubercle not broad at apex ( Tsuneki 1954: fig. 13); median and lower frons without rugae ( Tsuneki 1954: fig. 12); upper frons longitudinal carina distinct anteriorly, not reaching anterior ocellus ( Tsuneki 1954: fig. 12); gena with several sturdy, oblique transverse rugae near mandible area; lower gena with fine, sparsed punctures; pronotal collar not elevated medially, lateral angles sharp ( Tsuneki 1954: fig. 10); scutum without transverse striations anteriorly; scutellum dull; omaulus narrowed; dorsal surface of petiole smooth and pygidial area punctate medially.

Color pattern. Body black with shiny aspect, except the following: mandible medially (reddish brown apically), labrum, palpi, scape, pedicel, fore tibia and tarsus, mid tibia, trochanter and tarsus fulvous; flagellomeres dark brown [flagellomere I-II fulvous]; pronotal lobe whitish; tegula and forewing veins dark brown; hind trochanter reddish brown, tibia apically and tarsus dark brown; setae on margin of clypeus and on mandible pale.

Head. Mandible tridentate apically; setae on mandible sparse, long as pedicel length. Labrum pentagonal, round toward apex (Fig. 2a View Figure 2 ). Clypeus moderately convex, with coarse punctures, setae on margin of clypeus sparse, long as labrum length, free margin of clypeal lobe truncate medially (Fig. 2a View Figure 2 ). Median and lower frons rugose laterally, irregularly microstriate mesally, with a sturdy frontal median longitudinal carina, inter-antennal tubercle long, equal to midocellus diameter, distinctly broad at apex (Fig. 2a View Figure 2 ); upper frons with fine punctures, longitudinal carina distinct, reaching anterior ocellus but feeble (Fig. 2b View Figure 2 ), ocellar triangle nearly flat, with fine punctures, sparsely distributed (Fig. 2b View Figure 2 ); vertex behind ocelli shiny [dull], with fine sparsed punctures (Fig. 2b View Figure 2 ). Gena with dense sturdy transverse rugae, lower gena with coarse punctures. Occipital carina narrow, not foveolate (Fig. 2b View Figure 2 ); inner-orbital sulcus broad, with inner marginal carina distinct, inconspicuously foveolate (Fig. 2a View Figure 2 ); outer-orbital sulcus broad, hind marginal carina inconspicuous, inconspicuously foveolate.

Gaster segments with fine sparsed puncture (Fig. 2f View Figure 2 ). Pygidial area punctate, oval and concave (Fig. 2g View Figure 2 ).

Male. Unknown

Distribution.

China (Guizhou, Yunnan).

Etymology.

The name frontirugatus , is junction of Latin words: front (= face) and rugatus (= rugae); referring to rugose on median and lower frons.
