Diagnosis
This species resembles C. congruus (Walker, 1860) in sharing: median and lower frons microstriate, with a sturdy frontal median longitudinal carina (Fig. 4a); upper frons with fine and coarse punctures, frontal carina distinct anteriorly, not reaching anterior ocellus (Fig. 4b); ocellar triangle flat, gena with several sturdy oblique transverse rugae medially, lower gena with weak striations; outer-orbital sulcus broad; notaulus deeply grooved (Fig. 4j); propodeal enclosure triangular, with sturdy longitudinal rugae anteriorly, slender dense, longitudinal rugae laterally (Fig. 4k); pygidial area oval shaped (Fig. 4h). It can be differentiated from C. congruus by labrum, in female, pentagonal, longer than wide (Fig. 4a), in male, wider as long, deeply emarginated apically forming two rounded lobes (Fig. 4d); clypeus slightly convex; free margin of clypeal lobe nearly truncate medially, teeth inconspicuous (Fig. 4a); inter-antennal tubercle without T-shaped at apex (Fig. 4b); inner-orbital sulcus narrowed, inconspicuously foveolate (Fig. 4a); occipital carina foveolate (Fig. 4b); anterior pronotal ridge strongly marked (Fig. 4f); in female, fovea absent on scutum posterior margin (Fig. 4f); admedian line conspicuous in female, inconspicuous in male; parapsidal line conspicuous, and metanotum with inconspicuous rugae medially (Fig. 4f). Carinostigmus congruus (Walker) has the following characters: labrum triangular, broadly rounded at apex; clypeus strongly convex at middle; free margin of clypeal lobe slightly emarginate medially, with two distinct lateral small teeth (Krombein 1984[1]: fig. 9); inter-antennal tubercle with T-shaped at apex (Krombein 1984[1]: fig. 15); inner-orbital sulcus broad, distinctly foveolate (Krombein 1984[1]: fig. 3); occipital carina not foveolate; pronotal collar ridged weakly marked; in female, fovea present on scutum posterior margin; admedian and parapsidal lines inconspicuous, and metanotum smooth medially (Krombein 1984[1]: fig. 39).

Color pattern. Body black with shiny aspect, except the following: mandible yellowish, apically dark; labrum yellowish with ivory marked medially; palpi pale; scape and pedicel extensively yellowish; flagellomeres I–III yellowish, remaining darker; pronotal lobe ivory with yellowish spot; tegula fulvous; forewing veins dark brown; legs fulvous except mid and hind femur reddish brown; pale setae on clypeal margin and on mandible.
Head. Mandible tridentate apically; setae on mandible sparsed, long, longer than labrum length. Labrum pentagonal, rounded toward apex (Fig. 4a). Clypeus slightly convex, with coarse punctures; setae on margin of clypeus sparsed, long as labrum length; free margin of clypeal lobe nearly truncate, sinuous, not forming reflexed teeth (Fig. 4a). Median and lower frons microstriate, with a sturdy frontal median longitudinal carina (Fig. 4a), inter-antennal tubercle short, less than midocellus diameter (Fig. 4b); upper frons smooth, with fine and coarse punctures, frontal carina distinct anteriorly, not reaching anterior ocellus (Fig. 4b). Ocellar triangle nearly flat, finely punctate [impunctate]; vertex behind ocelli, finely punctate [impunctate]; gena with several sturdy transverse rugae medially; lower gena with weak striations. Occipital carina broad and foveolate as Fig. 4b; inner-orbital sulcus narrow as flagellomere I width, with inner marginal carina distinct, inconspicuously foveolate (Fig. 4a); outer-orbital sulcus broad as pedicel width, hind marginal carina distinct, inconspicuously foveolate.
Mesosoma. Pronotal collar smooth, strongly elevated mesally, ridged inconspicuous anteriorly, weakly marked, lateral angles blunt (Fig. 4f). Scutum with fine punctures, sparsely distributed, several slender transverse striations anteriorly (Fig. 4j); admedian line conspicuous, extending to one third of scutum length; notaulus deeply grooved and foveolate, extending to only anterior of scutum length (Fig. 4j); parapsidal line inconspicuous (Fig. 4f). Scutellum dull aspect densely micropunctated; metanotum with dense, slender, longitudinal rugae laterally, weak medially (Fig. 4f). Mesopleuron with fine punctures, sparsely distributed; omaulus and hypersternaulus narrowed as pedicel width, inconspicuously foveate [distinctly foveolate]; scrobal sulcus absent (Fig. 4g). Propodeal enclosure shallowly impressed, triangular, with sturdy longitudinal rugae anteriorly, slender dense, longitudinal rugae laterally (Fig. 4k); propodeum posteriorly with oval median groove, slender dense transverse rugae anteriorly, smooth medially (Fig. 4k); propodeal side presenting obliques and regular striae, sparsely distributed (Fig. 4g).
Legs. Outer surface of hindtibia without spines.
Metasoma. Petiole dorsal surface sub quadrate (cross section), basal width narrower than apically (Fig. 4c), side smooth. Gaster segments III–V [IV–VI] with fine sparsed punctures, rest impunctate (Fig. 4i). Pygidial area punctate anteriorly, oval shaped (Fig. 4h).
Male (Figs 4d, e, 5e). Same as female except mandible ivory, reddish brown apically; labrum, scape beneath and pedicel ivory, remaining scape and flagellomeres fulvous; flagellomeres without tyloids; forewing veins brown to dark brown; legs ivory to fulvous; setae on margin of clypeus and on mandible fulvous and short, less than pedicel length; mandible bidentate apically; labrum notched, deeply emarginated at apex; clypeus slightly microstriate, convex, impunctate; gena with several sturdy oblique transverse rugae near eye; fovea present on scutum posterior margin; parapsidal line inconspicuous.
Distribution
China (Yunnan).
Etymology
The name vesulcatus, is derived from the Latin words ve- (= without) and sulcatus (= sulcate), referring to the scrobal sulcus absent.
