Type material.
Holotype: ♀, China: Yunnan: Jinghong: Xishuangbanna National Forest Park, 22°01'N, 100°52'E, 31.VII.2003, 600-1000 m, coll. Qiang Li (YNAU). Paratypes: 6♀8♂, same locality and date as holotype, coll. Tingjing Li, Peng Wang (ZJU); 1♂, China: Yunnan: Lincang, 23°53'N, 100°05'E, 3.V.2005, coll. Baoxin Dong; 1♂, China: Yunnan: Ruili, 24°01'N, 97°51'E, 29.IV.1981, coll. Junhua He (YNAU).
Diagnosis.
This new species can be separated from all other Carinostigmus species from China by the following character combinations: mandible reddish brown basally; legs largely fulvous; labrum truncate apically; free margin of median lobe of clypeus broadly produced; median frons rugulose; occipital carina broad, without foveolate; lateral angles of pronotal collar not projected; metanotum smooth medially; propodeum with large smooth area medially; petiole dorsal with irregularly weak rugae basally; pygidial area depressed. It is closely related to C. congruus ( Walker) 1860, but differs from it in the following characters (states of C. congruus in brackets): inter-antennal tubercle without T-shape at apex (inter-antennal tubercle with T-shaped at apex); inner orbital furrow inconspicuously foveolate (inner orbital furrow distinctly foveolate); pronotal ridge strongly marked (pronotal ridge weakly marked), slightly emarginate in middle (not emarginate in middle); occipital carina broad as Fig. 4B View Figure 4 (occipital carina narrow as Fig. 3B View Figure 3 ); lower gena with dense, sturdy, longitudinal rugae medially (lower gena without rugae medially); notaulus inconspicuously grooved, extending to one third of scutum length (notaulus strongly impressed, extending to anterior ¼ of scutum length); propodeum with smaller smooth area than C. congruus ; petiole dorsal with few irregularly weak rugae basally (petiole dorsal without rugae); petiole laterally smooth (petiole laterally with a few weak carinae or smooth) and pygidial area u-shaped (pygidial area oval shaped).

Distribution.
China (Yunnan).
Etymology.
The name, Carinostigmus rugipunctatus , is derived from the Latin words ruga (= ruga, wrinkle) and punctum (= puncture), referring to the lower gena with coarse punctures mixed with rugae.
