A new solitary endoparasitoid of the larva of Bazaria turensis Ragonot, 1887 (Lepidoptera, Pyralidae) in Qinghai province, China, Campoplex bazariae Sheng, sp. n., belonging to the subfamily Campopleginae (Hymenoptera, Ichneumonidae), is reported. Illustrations of the new species are provided.

Campoplex Gravenhorst, 1829, belonging to the subfamily Campopleginae (Hymenoptera: Ichneumonidae), comprises 209 species (
The hosts of Campoplex Gravenhorst mainly belong to Coleophoridae, Gelechiidae, Pyralidae, Tortricidae, Yponomeutidae, etc. (
In the last five years the authors have been exploring Qinghai Province, Ningxia Hui Autonomous Region and Inner Mongolia Autonomous Region, situated in northwestern China, and have collected large numbers of ichneumonids. In this article, one new species of Campoplex is reported, reared from the larva of Bazaria turensis Ragonot, 1887 (Lepidoptera, Pyralidae), from Qinghai Province, P.R. China.
Mature larvae of the host, Bazaria turensis, were collected on 28 August 2013 by Mao-Ling Sheng. Cocoons of the host were collected on 21 May 2014 by Yan-Ling Zhang, from a forest where there had been an outbreak lasting at least three years, and brought to the laboratory. The forest is located in Dulan County, Qinghai Province. The forest is a shrubbery composed of Nitraria tangutorum Bobrov, Lycium chinense var. potaninii (Pojarkova) A.M. Lu and Kalidium foliatum (Pallas) Moquin-Tandon. Mature larvae were maintained in a nylon cage at room temperature. The pupae were stored individually in glass tubes with a piece of filter paper dipped in distilled water to maintain moisture and plugged tightly with absorbent cotton. Glass tubes are 60 mm long and 6 mm diameter. After the emergence of moths and parasitoids was complete, all remaining pupae were dissected to record their condition (i.e. status of moths, and parasitism).
Specimens were compared with material from the Natural History Museum (NHM), London, UK. Morphological terminology is mostly based on
Images of whole insects were taken using a CANON Power Shot A650 IS. Other images were taken using a Cool SNAP MPS Color attached to a Zeiss Discovery V8 Stereomicroscope and captured with QCapture Pro 7.
Type specimens are deposited in the Insect Museum, General Station of Forest Pest Management (GSFPM), State Forestry Administration, People’s Republic of China.
Campoplex Gravenhorst, 1829. Ichneumonologia Europaea, 3: 453. Type-species: Ichneumon difformis Gmelin, 1790. Designated by Westwood 1840.
Eye slightly or not at all emarginate opposite antennal socket. Occipital carina joining hypostomal carina above base of mandible, or reaching directly to base of mandible. Area superomedia and area petiolaris confluent, junction between them usually discernible, combined area moderately wide. Area dentipara completely bordered by carinae. Apex of propodeum usually not reaching middle of hind coxa. Areolet usually present. 2m-cu inclivous. Basal portion of first tergite subcylindric and less than 3.0× as long as deep, suture between tergite and sternite approximately at or a little below mid-height. Apex of male gonosquama rounded above or with a very shallow emargination. Ovipositor sheath about 3–4× as long as apical depth of metasoma.
The specific name is derived from the host’s name.
Holotype, female emerged from cocoon of Bazaria turensis on 20 July 2014 reared by Yan-Ling Zhang, CHINA: Balong, 2860m, Dulan County, Qinghai Province. Paratypes: 2 females, same data as holotype. 1 male, same data as holotype except 15 September 2014. 1 female, 1 male, CHINA: Nuomuhong, 2690m, Dulan County, Qinghai Province, 28 August 2013, Mao-Ling Sheng.
Face finely coriaceous, with dense punctures. Interocellar area with distinct punctures. Postocellar line 1.6–1.7× as long as ocular-ocellar line. Postscutellum with fine dense distinct punctures. First tergite from base to apex strongly evenly convex, smooth, shiny. Second and subsequent tergites finely coriaceous. Apical margins of tergites 6 and 7 with deep median triangular emarginations. Ovipositor slightly, evenly curved upwards. Head except mandibles and maxillary and labial palpi, mesosoma and all tergites entirely black.
Female. Body length 7.5–8.0 mm. Fore wing length 5.5–5.8 mm. Ovipositor sheath length 2.7–2.9 mm.
Head. Inner margins of eyes slightly convergent ventrally. Narrowest width of face (Fig.
Mesosoma. Lateral concavity of pronotum with dense oblique wrinkles, upper-posterior portion with dense coarse irregular punctures, distance between punctures 0.2–0.5× diameter of puncture, upper posterior margin with dense fine punctures. Epomia distinct. Mesoscutum (Fig.
Metasoma. First tergite (Fig.
Color (Fig.
Male. Body length 8.0–8.2 mm. Fore wing length approximately 6.0 mm. Median portion of frons with dense transverse wrinkles. Apex of gonosquama more or less horny. Median portion of mandible reddish brown. Tegula yellow, median portion asymmetrically blackish brown. Mid and hind tarsi dark brown.

Campoplex bazariae Sheng is a solitary endoparasitoid of the larva of Bazaria turensis, spinning its cocoon in deciduous leaves (Fig.
This new species is similar to C. ovatus (Brischke, 1880) and can be distinguished from the latter by the following combination of characters: petiole of areolet (Fig.
