D e s c r i p t i o n of: Body length 16 mm . Flagellum setiform, with 42 flagellomeres, flagellomeres slightly thickened centrally, tyloids lacking. Temples slightly and roundly narrowed behind eye. Distance of lateral ocellus to compound eye about 1.1x its diameter. Frons with some fine transverse striae. Face, clypeus and gena with dense puncture, clypeus with slightly concave apical margin. Malar space 0.4x as long as the basal mandibular width. Genal carina meeting the hypostomal one far from mandibular base. Hypostomal carina not elevated. Mesosoma with pale brownish hairs. Notaulus impressed in the anterior third of mesoscutum. Lateral fields of mesoscutum with superficial puncture, smooth. Mesopleurum and metapleurum with strong dense puncture. Mesopleurum with some radial striae in front of speculum.Scutellum strongly pyramidal, without lateral carina. Propodeum as in Trogini , with strong carinae and coarse rugulo-punctured structure. Area basalis not differentiated. Area superomedia strongly elevated, transversely sickle-shaped and smooth. Area posteroexterna and petiolaris with transverse rugae. Femur III slender, about 5.2x as long as high, with dense puncture. Areolet pentagonal, frontal distance of intercubiti 2x its diameter, 2mcu reaching areolet in its middle. Nervulus postfurcal. Postpetiole moderately widened. Lateral field of postpetiole striate, about 1x as wide as the median field, median field strongly striate. Gastrocoelus large, with longitudinal striae. Thyridium oblique, about as wide as the thyridial interval. The interval as wide as the median field of postpetiolus. Second tergite 0.75x as long as wide. Tergites 2-5 with coarse rugulo-puncture, matte, tergites 2-4 with median longitudinal striation. Coloration: Black. Ivory are flagellar ring (stripe ventrally from flagellomere 5-12, and dorsally from flagellomere 8-17), mandible, palps, labrum, clypeus, face, gena (except black malar stripe), outer orbits, frontal orbit up to lateral ocellus, scapus below, anterior and upper margins pf pronotum, tegula, subtegular ridge, lower 2/3 of mesopleurum mainly, two longitudinal stripes on mesoscutum, carinal triangle, metapleurum centrally, coxae and trochanters I-II, ventral and dorsal spots on coxa III and trochanter III. Legs I- II ivory on frontal side and brownish caudally. Hind leg reddish-yellow, tarsus III more cream-yellow. Postpetiolus with small posterolateral yellowish spots, metasoma otherwise black. Wings brownish-hyaline, pterostigma black. unknown. R e m a r k: The specimen has the characteristical structures of scutellum, propodeum, and metasoma as described for the genus Trogichneumon ( HEINRICH 1968b: 82-84 ) . However, the of the typical Trogichneumon annaelisae HEINRICH differs by its black flagellum and the coloration of mesoscutum and legs. D i s t r i b u t i o n: China .
