Eight species of the genus
According to recent publications (
The Oriental species of
In the last four years the author has been exploring Jiangxi Province, situated in the northern border of the Oriental part of China, Jilin Province and Ningxia Hui Autonomous Region, both situated at the southern border of the Palaearctic part of China, and has collected large numbers of ichneumonids. New discoveries have been reported (
Specimens were collected using entomological nets in the forests of Quannan, Ji’an and Qianshan Counties, Jiangxi Province; Liupanshan Natural Reserve, Ningxia Hui Autonomous Region; Baihe, Jilin Province (CHINA).
Images of whole bodies were taken using a CANON Power Shot A650 IS. Other images were taken using a Cool SNAP 3CCD attached to a Zeiss Discovery V8 Stereomicroscope and captured with QCapture Pro version 5.1.
The morphological terminology is mostly that of
Type specimens are deposited in the Insect Museum, General Station of Forest Pest Management, State Forestry Administration, People’s Republic of China.
Upper tooth of mandible longer than lower tooth. Genal carina joining hypostomal carina above base of mandible. Occipital carina complete. Without epomia. Lower half of mesopleuron weakly convex. Posterior transverse carina of propodeum usually present. Propodeal spiracle round or slightly elongate. Areolet present, front side truncate or pointed. 2m-cu with two closely spaced bullae or with one that is 0.5 to 1.0 times as long as the section of 2m-cu behind bulla. First tergum evenly and strongly tapered toward base. Apical portion of metasoma weakly to strongly compressed. Ovipositor sheath approximately 0.6 times as long as hind tibia. Subapical portion of ovipositor with a dorsal notch.

The name of the new species is based on the median longitudinal carina of the face.
Median portion of face strongly convex, with distinct median longitudinal carina. Areolet petiolate. Scutellum and postscutellum with dense punctures. Claws pectinate. Hind wing vein 1/cu approximately 3.8 times as long as cu-a. First tergum approximately 2.5 times as long as apical width, slightly narrowed towards base. Ovipositor almost straight. Face black with latero-median yellowish white spots.
Female. Body length about 10.0 mm. Fore wing length about 8.0 mm. Ovipositor sheath length about 2.0 mm.
This new species can be easily distinguished from other species of this genus as the face has a distinct median longitudinal carina, the areolet is clearly petiolate, the first tergum is slightly narrowed towards the base and the inner profile of the basal half of the flagella has a particular structure, a strong longitudinal carina.
The specific name is derived from the face being fulvous.
Face whitish yellow. Hind coxae brownish red entirely. Basal portion of lower margin of mandible with distinct semitransparent edge. Antenna with 33 flagellomeres. Mesosoma shining. Claws simple. Ovipositor strongly upcurved.
Female. Body length 8.5 to 9.5 mm. Fore wing length 6.5 to 7.5 mm. Ovipositor sheath length 1.5 to 2.0 mm.
The specimen from Shuangjiang Forest Farm, Ji’an, Jiangxi Province, has the first tergum more or less and irregularly darkish red.
Similar to
The specific name is derived from the entirely yellow legs.
Gena with fine granular texture, almost impunctate. Mesosoma with fine leathery texture. Legs yellowish white, except apical portions of middle and hind tibiae and tarsi yellowish brown to darkish brown. Claws pectinate.
Female. Body length about 7.2 mm. Fore wing length about 5.8 mm. Ovipositor sheath length about 1.7 mm.
This new species is similar to
The specific name is derived from the face, which has a dark fleck.
Mesosoma with fine leathery texture. Ovipositor sheath shorter than first tergum. Face white with median longitudinal black band. Flagellomeres 10 to 16 white. Scutellum yellowish white. Basal-median portion of first tergum white to yellowish white.
Female. Body length about 8.3 mm. Fore wing length about 6.2 mm. Ovipositor sheath length about 1.6 mm.
The face of one male specimen is almost enitrely black, with only very narrow sublateral yellow lines. Tergum 1 of male with basal and apical portions white to unevenly brownish yellow with two small longitudinal black spots.
Similar to
The name of the new species is based on the leg being brownish red.
Hind wing 1/cu approximately 4.7 times as long as cu-a. Posterior transverse carina of propodeum weakly present centrally. Face black, median portion of inner orbit yellow; legs almost entirely brown. Apical portion of tergum 1, terga 2 to 3, basal portion of tergum 4 and subposterior margin of tergum 5 reddish brown. Stigma yellowish brown.
Female. Body length about 7.0 mm. Fore wing length about 5.8 mm. Ovipositor sheath length about 1.5 mm.
