Coelichneumon lineiscutis View in CoL HEINRICH, 1966, new male

M a t e r i a l: Nepal, Nawakot Trisuli Khola, 2200- 1600 m, Dhunche , Syabru Bensi , 1♂ 28.IX.1982, leg. Holzschuh ( ZSM).

D e s c r i p t i o n: ♂: Body length 13.5 mm. Flagellum with 40 flagellomeres, bristleshaped; 1 st flagellomere 2.5x longer than wide. Tyloids on flagellomeres 9-19, linear, maximally as long as their flagellomeres. Temple strongly and almost linearly narrowed behind eye, dorsally 0.6x as long as eye. Distance of lateral ocellus to eye 1.1x ocellar diameter. Malar space 0.6x as long as width of mandibular base. Notaulus impressed at frontal margin of mesoscutum. Mesoscutum with scattered punctures on lateral fields, shining. Scutellum slightly elevated, as long as wide, with lateral carina in basal 0.4. Hind femur 4.9x longer than wide. 2 nd tergite 1.1x longer than wide. Structure otherwise as described for the ♀ ( HEINRICH 1966: 224-225).

Colour: Black with rich yellow colouration as described for the ♀ ( HEINRICH 1966). The colouration differs from ♀ by the following features: Scape yellow ventrally, antenna otherwise black. Clypeus and face entirely yellow. Paramedian longitudinal stripes on mesoscutum long, reaching the frontal margin of mesoscutum. Scutellum yellow, with narrow black median stripe. Area superomedia yellow, with small black central spot. Hind coxa black with small yellow spots dorsally and apico-ventrally. 2 nd to 6 th tergites with large posterolateral yellow spots.

R e m a r k: This species belongs to the C. flavolineatus -group of Oriental Coelichneumon THOMSON containing several closely related taxa ( HEINRICH 1966) which are difficult to separate. The ♂ which is described here resembles C. flavolineatus (CAMERON) by the long paramedian yellow stripes on mesoscutum and lateral carina of the basal scutellum, but differs by the entirely black flagellomeres and reduced yellow colour pattern of the mesosternum.

D i s t r i b u t i o n: Known fromMyanmar and Laos ( RIEDEL 2017), new record for Nepal.
