Type material.
Holotype: ♀, China: Hainan: Jianfengling Mount, 18°41'N, 108°52'E, 6.VI.2007, 900-950 m, No. 200707957, coll. Jingxian Liu (ZJU). Paratypes: 1♀, same locality as holotype, 7.VI.2007, No. 200707997; 1♂, same locality and date as holotype, No. 200707955; 1♀, China: Yunnan: Jinghong: Menghai: Bulang Mountain, 21°56'N, 100°26'E, 2018.IV.24-V.17, No. 2019000007, coll. Malaise trap (YNAU).
Diagnosis.
This new species can be separated from all other Carinostigmus species from China by the following character combinations: free margin of clypeus emarginate; median and lower frons with broad frontal median furrow; upper frons without longitudinal carina; occipital carina broad, distinctly foveolate; admedian line extending to half of scutum length; mesopleuron with longitudinal rugae posteriorly; propodeum with large smooth area medially. It is closely related to C. iwatai (Tsuneki, 1954), but differs from it in the following characters (characters of C. iwatai in brackets): inter-antennal tubercle short, less than midocellus diameter (inter-antennal tubercle long, more than midocellus diameter); ocellar triangle and vertex behind ocelli impunctate (ocellar triangle and vertex behind ocelli finely punctate); occipital carina broad as Fig. 2B View Figure 2 , distinctly foveolate (occipital carina narrow as Fig. 3B View Figure 3 , without foveolate); outer and inner orbital furrows narrow as Fig. 2A View Figure 2 (outer and inner orbital furrows broad as Fig. 3A View Figure 3 ); pronotal collar without rugae (pronotal collar with sparse and sturdy rugae); scutum with transverse striations anteriorly (scutum without striations); parapsidal and admedian lines inconspicuous (parapsidal and admedian lines distinct); metanotum with dense, slender longitudinal rugae medially (metanotum without rugae medially); omaulus broad, 1.3 × pedicel width (omaulus narrow, 0.8 × pedicel width); scrobal suture lacking (scrobal suture present, short as Fig. 4I View Figure 4 ); propodeum posterior with large smooth area medially (propodeum posterior with small smooth area medially); petiole laterally smooth (petiole laterally with few weak carinae) and pygidial area smooth, u-shaped (pygidial area punctate medially, oval shaped).

Distribution.
China (Hainan, Yunnan).
Etymology.
The name, Carinostigmus capiconvergens , is derived from the Latin words caput (= head) and con-vergo (= converge), referring to the head from above with temples distinctly convergent posteriorly.
