Coelichneumon (Intermedichneumon) superomediae nov.sp.

Holotypus: ♀ Laos, Hua Phan Prov., Phon-Pan, Umg. Ort Ban Saleui, 20°13´30´´N 103°59´26´´E, 1350-1900 m, 15.06.2013 KJa, leg. C. Holzschuh & natives (Linz).

D e s c r i p t i o n of ♀: Body length 12 mm. Flagella moderately lanceolate, with 41 flagellomeres; 1 st flagellomeres (without anellus) length 2.9x width, 13th segments square, flagellomeres beyond the middle attenuated, widest ones 1.8x as wide as long.

Temples strongly and roundly narrowed behind eyes ( fig. 4 ). Clypeus, face and frons with rather scattered puncture. Genae with very scattered puncture. Distance of lateral ocelli to the eyes about 1x as long as their diameter. Malar spaces about 0.4x as long as the width of mandibular bases. Genal carinae reaching the hypostomal ones close to mandibular bases.

Mesosoma with whitish hairs. Notauli impressed on frontal fourth of mesoscutum. Mesoscutum with rather dense punctures and fine granulation, but shining; mesopleura and metapleura punctate, speculum smooth. Scutellum moderately elevated, wider than long, with lateral carinae in the basal 0.3, with scattered puncture. Propodeum rounded, areae basalis and superomedia confluent, costulae behind the center of area superomedia ( fig. 13 ). 1 st lateral areae of propodeum with fine striation and some punctures, area petiolaris with coarse puncture. Hind coxae densely punctate, without scopa. Hind femora densely punctate, length 4.0x height. Areolets pentagonal, frontal distance of intercubiti about 2x their width, nervuli postfurcal.

Metasoma ( fig. 19 ) strongly oxypygous. Postpetiolus strongly widened, lateral fields about as wide as median field, the latter coarsely aciculate. Thyridia oblique, very wide, about 2x as wide as their interval. 2 nd tergite length 0.9x width, length of 3 rd tergite 0.6x its width. Tergites 2-5 with dense puncture and fine granulation, tergites 2-4 centrally with longitudinal rugae and striae, following tergites almost smooth and strongly shining. Seen from dorsal, ovipositor sheath c.0.7x as long as the seventh tergite.

Color: black. Cream-yellow are stripes on flagellomeres 7-17, palps, mandibular bases, clypeus, face except M-shaped black central spot, genae, complete orbits, lateral spots on scapes, propleura, anterior and upper margins of pronotum, two longitudinal stripes on mesoscutum, subtegular ridges, tegulae, lower mesopleura behind epicnemial carina, ventro-apical spots of mesosterna, carinal triangles, caudal 2/3 of metapleura, sides of scutellum, postscutellum, area superomedia confluent with wide spots on dentiparal areae, cranial spots on areae spiraculiferae, hind part of postpetiolus, large posterolateral spots on tergites 2-5 (almost confluent on tergites 4-5), narrow apical bands on tergites 6 and 7. Fore and middle legs yellowish, femora and tibiae with brown stripes caudally, fore and middle tarsi brown. Hind legs black, hind coxae with dorsal and ventro-apical yellow spots, hind femora reddish, black in the apical 0.2 and with diffuse yellowish marks ventrally, hind tibiae with subbasal ivory rings. Pterostigmas blackish-brown.

3 unknown.

R e m a r k: This new species is closely related to C. scopator nov.sp., but can be differentiated by the lack of scopa on hind coxa, form and color of area superomedia, narrower malar space, and slightly different coloration of metasoma.

D i s t r i b u t i o n: Laos.
