Campodorus Förster, 1869

Phagesorus Förster, 1869 (1868): 212, type-species: Tryphon caligatus Gravenhorst. Designated by Townes, Momoi & Townes, 1965.

Campodorus Förster, 1869 (1868): 213, type-species: Mesoleius melanogaster Holmgren, 1857 . Designated by Perkins, 1962.

Cuboscopesis Heinrich, 1952: 1080 , type-species: Cuboscopesis epachthoides Heinrich. Original designation.

Diagnosis. The diagnosis of the genus was modified from Townes (1970), Kasparyan (2003) and Sun et al. (2020).

Fore wing length 3.4–8.7 mm. Clypeus swollen medially near the margin; apical margin usually blunt at midline; usually sharp and projecting laterally as thin lobes. Upper tooth of mandible almost same length as lower tooth. Notaulus usually long and sharp, reaching front edge of mesoscutum. Mesopleuron with medium-sized to very fine punctures. Lateromedian longitudinal and posterior transverse carinae of propodeum usually present and strong. Area petiolaris sometimes large. Areolet absent; vein 1cu-a distal to M&RS. Hind wing vein 1-cu inclivous, longer than cu-a. Latero-median carinae of tergite 1 at least reaching to spiracle. Tergite 2 finely shagreened to scabrous, punctures small to almost absent.

Key to similar species of Campodorus

1. Lateromedian longitudinal carinae of propodeum ( Fig. 5 ) weak, anterior half absent. Base of tergite 1 with large deep median concavity. Posterior portion of postpetiole, tergite 2 and anterior portion of tergite 3 predominantly yellowish to reddish brown................................................................... C. concavus Wei & Sheng , sp. nov.

-. Lateromedian longitudinal carinae of propodeum distinct and strong. Base of tergite 1 with normal median concavity. Tergites black, without yellowish to reddish brown spots............................................................. 2

2. Areas superomedia and petiolaris of propodeum completely confluent; lateromedian longitudinal carinae divergent posteriorly........................................................................................... 3

-. Areas superomedia and petiolaris of propodeum separated by transverse carina; lateromedian longitudinal carinae not or slightly divergent posteriorly................................................................................... 4

3. Basal parts of lateromedian longitudinal carinae almost parallel, slightly divergent posteriorly; area between lateromedian longitudinal carinae smooth. Lower lateral portion of face with large yellow spots. Hypopygium predominantly yellowish white...................................................................... C. rasilis Sheng, Sun & Li, 2020

- Lateromedian longitudinal carinae from base strongly divergent posteriorly; area between lateromedian longitudinal carinae with distinct wrinkles. Face entirely black. Hypopygium black......................... C. crassitarsus ( Uchida, 1935)

4. Area basalis and area superomedia of propodeum separated by strong transverse carina. Ovipositor sheath 3.0 × as long as maximum width, with dorsomedian portion distinctly widened. Hind tibia black, with small cream subbasal spot.................................................................................. C. punctatus Sheng, Sun & Li, 2020

- Area basalis and area superomedia of propodeum completely confluent. Ovipositor sheath 4.2 × as long as maximum width, dorsal side straight. At least basal half of hind tibia yellowish white....................... C. ciliatus (Holmgren, 1857)
