Figs 17–25

Diagnosis

The new species may easily be distinguished from most other congeners in coloration ( Fig. 17 ): by the combination of an almost entirely brownish red metasoma, blackish hind femur and hind coxa, and whitish yellow hind trochanter and a broad ring on the hind tibia. Face ( Fig. 18 ) flat, with dense fine punctures, distance between punctures 0.2–0.5 × diameter of puncture. Upper tooth of mandible slightly shorter than lower tooth. Median longitudinal carinae and median portion of posterior transverse carina of propodeum weak or almost absent. Metasomal tergites shagreened. Ovipositor sheath ( Figs 17 , 25 ) approximately 4.2 × as long as its median width, dorsal and ventral margins almost parallel.

Differential diagnosis

The new species is similar to C. micropunctatus ( Uchida, 1942) , but can be distinguished from the latter by the following combinations of characters: median longitudinal carinae of propodeum weak (male) or indistinct (female). Ovipositor sheath 4.5 × as long as maximum width. Flagellum brownish black ventrally, black dorsally. Hind femur black. Campodorus micropunctatus : median longitudinal carinae of propodeum distinct and strong. Ovipositor sheath 1.9 × as long as maximum width. Flagellum and hind femur reddish brown.

Etymology

The specific name is derived from the type locality.
