Three species of
The species distributed in Ethiopian Region were reported by
In the last four years the authors have been exploring Jiangxi Province, situated near the northern border of the Oriental part of China, and have collected large numbers of ichneumonids. In this article, the species belonging to
Specimens were collected using entomological sweep nets in the forests of Anfu, Ji’an, Longnan, Qianshan, Quannan and Zixi Counties, Jiangxi 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
The new species were checked against the species described by
Type specimens are deposited in the Insect Museum, General Station of Forest Pest Management (GSFPM), State Forestry Administration, People’s Republic of China.

The specific name is derived from the terga being entirely brown.
Female. Body length 5.5 to 6.0 mm. Fore wing length 4.0 to 4.5 mm. Antenna length 6.0 to 6.5 mm. Ovipositor sheath length 1.5 to 1.8 mm.
Face (
Pronotum, mesoscutum and dorsal and ventro-posterior portions of mesopleuron with fine granulose texture. Anterior margin of pronotum with indistinct fine longitudinal wrinkles; lateral concavity with indistinct and short transverse wrinkles. Mesoscutum slightly convex, median portion with dense oblique longitudinal wrinkles. Notaulus evident, reaching about 0.7 the distance to posterior margin of mesoscutum. Scutellum weakly convex, with texture as that of mesoscutum, but relatively finer than that; subapical portion with indistinct transverse concavity; lateral carina reaching to the concavity. Postscutellum weakly convex, posterior margin with fine carina-shaped edge. Median portion of mesopleuron (
First tergum 2.1 to 2.2 times as long as apical width, evenly and strongly narrowed toward base, median portion strongly arched, with dense, even and fine longitudinal wrinkles, dorsolateral carinae indistinct, ventrolateral carinae complete. Spiracle located slightly anterior of middle. Second tergum trapeziform, median portion with fine arcuate to circular lines (
