Diagnosis.
This species is similar to C. saigusai (Tsuneki, 1966) in having the following: labrum broad, wider than long, sub quadrate (Fig. 3j View Figure 3 ); vertex behind ocelli impunctate (Fig. 3b View Figure 3 ); gena with several sturdy oblique transverse rugae near mandible area; occipital carina narrowed, distinctly foveolate (Fig. 3b View Figure 3 ); inner and outer-orbital sulcus narrowed (Fig. 3a View Figure 3 ); notaulus inconspicuous; scutellum dull, with fine sparsed punctures (Fig. 3f View Figure 3 ); metanotum densely covered by sturdy longitudinal rugae; omaulus broad as midtibial width, scrobal sulcus absent (Fig. 3g View Figure 3 ); lateral surface of propodeum with sparsed sturdy or slender oblique longitudinal rugae anteriorly, and irregular reticulation posteriorly (Fig. 3g View Figure 3 ); petiole dorsal surface nearly cylindrical, slightly bowed (Fig. 3c View Figure 3 ). Distinguished from C. saigusai by setae on mandible short, shorter than pedicel length; clypeus with coarse punctures (Fig. 3a View Figure 3 ); free margin of clypeal lobe with four teeth, median lobe broadly produced, nearly truncate, with two small inconspicuous lateral teeth, slightly reflexed apically (Fig. 3j View Figure 3 ); median and lower frons dull (Fig. 3a View Figure 3 ); upper frons with fine punctures, frontal carina distinct anteriorly, not reaching anterior ocellus (Fig. 3b View Figure 3 ); pronotal collar slightly elevated medially; admedian line inconspicuous; parapsidal line well-marked (Fig. 3f View Figure 3 ); propodeal enclosure shallowly impressed, triangular; posterior surface of propodeum with triangular median groove, several fairly slender oblique longitudinal rugae anteriorly, and a large smooth area medially (Fig. 3k View Figure 3 ). Carinostigmus saigusai (Tsuneki) has the following characters: setae on mandible long; clypeus impunctate; free margin of clypeal lobe with three distinct teeth medially ( Tsuneki 1966: fig. 25); median and lower frons not dull; upper frons impunctate, without frontal median carina; pronotal collar smooth; admedian line conspicuous; parapsidal line inconspicuous; propodeal enclosure deeply impressed, sub triangular; posterior surface of propodeum with rectangular median groove, and a small smooth area medially ( Tsuneki 1966: fig. 27).

Color pattern. Body black with shiny aspect, except the following: mandible ivory white with yellowish translucent margins (at minus apically), labrum, palpi, scape ventrally, and pronotal lobe ivory white; scape dorsally, pedicel, flagellomeres I-III fulvous (remains progressively dark), and tegula fulvous; forewing veins brown to dark brown; fore coxa extensively, trochanter, tibia, tarsi yellowish to fulvous, rest dark brown; mid coxa extensively, trochanter, base and apex of femur, tibia, tarsi yellowish to fulvous, rest dark brown; hind coxa, trochanter, tarsus yellowish to fulvous, tibia basally ivory, remaining dark brown; pale setae on clypeal margin and on mandible.
Head. Mandible tridentate apically; short setae, shorter than pedicel length on mandible, sparsed. Labrum sub quadrate (Fig. 3j View Figure 3 ). Clypeus slightly convex [nearly flat], with coarse punctures; setae on margin of clypeus sparse, long (Fig. 3a, j View Figure 3 ); free margin of clypeal lobe with four teeth, median apical margin of clypeal disk produced, nearly truncate, with two small inconspicuous lateral teeth, slightly reflexed, a strong tooth on apical margin of each lateral lobe (Fig. 3j View Figure 3 ). Median and lower frons irregularly microstriate, inter-antennal tubercle short, less than midocellus diameter (Fig. 3a View Figure 3 ); upper frons smooth, with fine punctures, frontal carina distinct on frons, not reaching to midocellus (Fig. 3b View Figure 3 ). Ocellar triangle nearly flat, impunctate, vertex behind ocelli impunctate. Gena with several sturdy transverse rugae near mandible area, lower gena with fine punctures medially, sparsely distributed. Occipital carina narrow, foveolate (Fig. 3b View Figure 3 ). Inner-orbital sulcus narrowed as pedicel width, with inner marginal carina distinct, coarsely foveolate (Fig. 3a View Figure 3 ); outer-orbital sulcus narrowed as pedicel width, hind marginal carina inconspicuous, inconspicuously foveolate.
Mesosoma. Pronotal collar slightly elevated medially, anterior pronotal ridge strong, lateral angles sharp and projected (Fig. 3f View Figure 3 ). Scutum with coarse punctures, several slender transverse striations anteriorly, fovea present on scutum posterior margin (Fig. 3f View Figure 3 ). Admedian line and notaulus inconspicuous [notaulus invisible], extending to only anterior of scutum length, parapsidal line distinctly marked. Scutellum dull, with fine sparsed punctures (Fig. 3f View Figure 3 ). Metanotum densely covered by sturdy longitudinal rugae. Mesopleuron with sturdy, dense, short longitudinal rugae posteriorly, hypoepimeral area with several slender long longitudinal rugae, omaulus broad as midtibial width, hypersternaulus narrowed as pedicel width, distinctly foveolate, scrobal sulcus absent (Fig. 3g View Figure 3 ).

Distribution.
China (Yunnan, Fujian, Hainan).
Etymology.
The name latidentatus , is derived from the Latin words: lateralis (= lateral, side) contracted to lati and dentatus (= toothed, dentate), referring to the strong tooth on the apical margin of the lateral lobe of the clypeus.
