Diagnosis
Scutellum ( Fig. 28 View Figs 28–34 ), lower portion of mesopleuron ( Fig. 29 View Figs 28–34 ) and propodeum with relatively long gray setae. Propodeum ( Fig. 31 View Figs 28–34 ) shiny, with distinct fine punctures, areae superomedia and petiolaris strongly roughened; anterior portion of area petiolaris with transverse wrinkles. Ovipositor sheath ( Figs 24 View Figs 24–27 , 34 View Figs 28–34 ) approximately 10 × as long as its maximum width. Apical portions of wings slightly darkened. Head and mesosoma ( Fig. 24 View Figs 24–27 ) almost entirely black. Tergite 3 red ( Fig. 32 View Figs 28–34 ).
Etymology
The name of the new species is based on the metasoma having one red tergite.

HEAD. Face ( Fig. 25 View Figs 24–27 ) approximately 1.8 × as wide as long, strongly convex, with distinct punctures, distance between punctures 1.0–3.0 × diameter of puncture; lower median portion with indistinct transverse wrinkles. Clypeus approximately 3.0 × as wide as long, smooth, almost shiny, with sparse punctures and long brown setae; apical margin approximately truncate. Mandible with long brown setae, upper tooth as long as lower tooth. Malar area slightly, indistinctly granulose. Malar space approximately 0.20 × as long as basal width of mandible. Gena ( Fig. 26 View Figs 24–27 ) almost smooth, with sparse, fine punctures, obviously evenly convergent posteriorly. Vertex ( Fig. 27 View Figs 24–27 ) with uneven fine punctures. Interocellar area with relatively dense punctures. Postocellar line 0.8 × as long as ocular-ocellar line. Antenna with 42 flagellomeres. Ratio of length from first to fifth flagellomeres: 6.0:4.0:3.5:3.5:3.5. Occipital carina complete, lower end reaching base of mandible.
MESOSOMA. Lateral concavity of pronotum with weak transverse wrinkles, upper-posterior portion with sparse fine punctures. Mesoscutum ( Fig. 28 View Figs 28–34 ) with distinct punctures, distance between punctures 0.5– 3.0 × diameter of puncture. Notaulus vestigial. Scutellum slightly convex, with sparse fine punctures and long gray-brown setae. Mesopleuron ( Fig. 29 View Figs 28–34 ) with uneven fine punctures, in lower portion of speculum largely smooth, shiny. Speculum with sparse punctures. Upper end of epicnemial carina reaching to 0.6-height of front margin of mesopleuron. Metapleuron slightly convex, with even fine punctures. Submetapleural carina complete, strong. Wings slightly brownish, hyaline. Fore wing ( Fig. 30 View Figs 28–34 ) with vein 1cu-a distal to 1/M approximately by 0.3 × length of 1cu-a. Areolet without or with short stalk, receiving vein 2m-cu approximately 0.5 × distance from vein 2rs-m to 3rs-m. 2-Cu approximately 1.5 × as long as 2cu-a. Hind wing vein 1-cu 1.5–2.0 × as long as cu-a. Ratio of length of hind tarsomeres from first to fifth approximately: 17.0:8.0:6.0:3.5:5.0. Propodeum ( Fig. 31 View Figs 28–34 ) evenly convex, with distinct punctures; area superomedia and area petiolaris confluent, strongly roughened; anterior portion of area petiolaris with indistinct transverse wrinkles. Propodeal spiracle oval.
METASOMA. First tergite ( Figs 32–33 View Figs 28–34 ) 2.6–2.7 × as long as posterior width. Postpetiole with weak sparse punctures. Spiracle circular, located at apical 0.4 of first tergite approximately. Second tergite approximately 0.9 × as long as posterior width. Ovipositor sheath approximately 10 × as long as its maximum width. Ovipositor ( Fig. 34 View Figs 28–34 ) evenly, strongly narrowed apically, with distinct subapical dorsal notch.
COLORATION ( Fig. 24 View Figs 24–27 ). Black, except following; lower lateral portion of face white; median portions of mandibles yellowish brown; maxillary and labial palpi, apical portions of fore femur, fore tibia, median portion of middle tibia and apical portion of hind femur yellow-brown; hind tarsus blackish brown; third tergite entirely or anterior half red; pterostigma and veins brownish black.
Male
Antenna with 43 flagellomeres. Median portions of mandibles, maxillary and labial palpi, fore and middle tibiae and tarsi and hind tibiae except apical portions yellow.
Host
One female of Ctenopelma rufofasciatum was reared from a ‘cocoon’ (chamber) of Cephalcia lariciphila (Wachtl, 1898) by Tao Li from Mentougou, Beijing.
Host foodplant
Larix principis -rupprechtii Mayr.
Differential diagnosis
According to the most recent revision of Ctenopelma from the Palaearctic ( Kasparyan 2004), the new species belongs to the C. lucifer subgroup in having gena convergent posteriorly, gena and mesosoma distinctly punctate, area superomedia separated from area petiolaris (but the new species is confluent) and ovipositor sheath longer. The new species can be easily dinstinguished from the only known species of the lucifer subgroup, C. lucifer ( Gravenhorst, 1829) , by the following combination of characters: area superomedia and area petiolaris confluent; anterior portion of median longitudinal carina of propodeum obliterated; face black, lower lateral portion with large white spots; frons and vertex entirely black; hind coxa, trochanter and femur entirely black; third tergite red. Ctenopelma lucifer : area superomedia separated from area petiolaris by carina; median longitudinal carina of propodeum complete and strong; face entirely yellow-brown; frons and vertex with laterally yellowish brown spots; hind coxa, trochanter and femur brown to darkish brown; tergites 2–4 red-brown.
