The species of Campodorus Förster, 1869 and a related species (Hymenoptera, Ichneumonidae) from China

Ten species of Campodorus Förster, 1869 are reported from China and fi ve species are new to science: C. albilineatus Sheng, Sun & Li sp. nov. from Guangxi Zhuang Autonomous Region in the Oriental part of China, C. punctatus Sheng, Sun & Li sp. nov. and C. rasilis Sheng, Sun & Li sp. nov. from Beijing, C. shandongicus Sheng, Sun & Li sp. nov. from Shandong Province and C. truncatus Sheng, Sun & Li, sp. nov. from Liaoning Province. Three species, C. ciliatus (Holmgren, 1857) and C. dauricus Kasparyan, 2005 collected from Liaoning Province and Mesoleius faciator Kasparyan, 2001 from Beijing, are new records for China. A key to species of Campodorus and a related genus known in China is provided.


Differential diagnosis
The new species is similar to C. ciliatus (Holmgren, 1857), but can be distinguished from the latter by the following combination of characters: median longitudinal carinae of propodeum ( Fig. 7)  Another Oriental species, C. orientalis Kasparyan, 1998, differs from the new species in having the mesothorax and hind coxa completely red, fi rst fl agellomere strongly elongate, 1.9 × as long as second, and areas of the propodeum before the level of the spiracle obliterated.

Etymology
The specifi c name is derived from the white bands on the hind margins of the metasomal tergites.
METASOMA. First tergite (Fig. 8) approximately 1.2 × as long as posterior width, strongly and evenly narrowed to base, slightly shagreened; dorsal median carinae reaching to middle; spiracle small, circular, located approximately at anterior 0.4 of fi rst tergite. Second and subsequent tergites (Figs 8-10) distinctly shagreened, with short brownish gray setae. Second tergite ( Fig. 9) approximately 0.6 × as long as apical  (Fig. 1). Black, except for following: apical half of scape ventrally and apical margin of pedicel more or less yellow brown. Clypeus, small median spot and two spots in lower corners of face (Fig. 2), mandible except teeth, maxillary palpi, labial palpi, tegulae, subtegular ridge, scutellum, postscutellum, fore and middle coxae and parts of tarsi, hind coxa dorsally, all trochanters, and subbasal portions of hind tibia whitish yellow. Fore and middle legs except coxae and parts of tarsi brownish yellow. Hind coxa ventrally and hind femur reddish. Posterior portions of metasomal tergites white. Sternites 2-4 broadly whitish in median part, sternites 5 and 6 black with anterior and posterior margins widely white.

Remarks
Campodorus albilineatus sp. nov. is the only species known from the Oriental part of China.

Differential diagnosis
In main peculiarities of coloration and most other diagnostic characters the Chinese specimens correspond to the holotype of Mesoleius faciator Kasparyan, 2001 (Russia, Chita Prov.), but differ in dense long pubescence of lateral parts of the propodeum; in having more antennal segments (39 fl agellomeres) and smaller body size (fore wing 6.6 mm long); the holotype of M. faciator has 36 fl agellomeres and fore wing is 8.1 mm long. Although described in the genus Mesoleius, Kasparyan (2001)  HEAD. Face (Fig. 12) approximately 1.8 × as wide as long, shagreened, almost fl at, with dense yellowish white setae; upper margin with median small tubercle. Clypeus approximately 3.3 × as wide as long, smooth, shiny, with sparse brown setae; apical margin sharp, subapical portion distinctly convex (Fig. 12). Mandible with sparse indistinct shallow punctures and brown setae; upper tooth slightly wider, longer than lower tooth. Malar area granulated; malar space approximately 0.5 × as long as basal width of mandible. Gena and vertex almost shagreened. Posterior portion of gena distinctly convergent posteriorly. Postocellar line approximately 0.9 × as long as ocular-ocellar line. Antenna with 39 fl agellomeres; ratio of length from fi rst to fi fth fl agellomeres approximately: 1.6:1.3:1.2:1.1:1.0. Occipital carina complete, lower end reaching hypostomal carina distinctly above base of mandible.

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) fl at, with dense fi ne 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

Etymology

Differential diagnosis
The new species is similar to C. ciliatus (Holmgren, 1857), but can be distinguished from the latter by the following combinations of characters: median longitudinal carinae of propodeum (Fig. 39) evenly divergent posteriorly; areas superomedia and petiolaris completely confl uent.

Ovipositor sheath 4.2 × as long as maximum width, slightly expanding posteriorly. Face entirely black. At least basal halves of hind basal three tarsomeres white.

Etymology

Discussion
The majority of Campodorus have been described from the Palaearctic and Nearctic Regions. Prior to this publication, only one species of Campodorus was known from the Oriental Region, from Myanmar (Kasparyan 1998), now a second species, C. albilineatus sp. nov., just described above, is known from the northern border of the Oriental part of China. Based on collections from Southern China, Guangdong, Guangxi, Fujian, Jiangxi and Yunnan Provinces, many species of Campodorus are still undescribed. The species of the Oriental Region deserve further research.
