Coelichneumon (Coelichneumon) hopponis (MATSUMURANA, 1912)

M a t e r i a l: Laos, Hua Phan Prov., Ban Saleui, Phon-Pan-Mt., 20°13´30´´N 103°59´26´´E, 1350- 1900 m, 13 16.IV.2012, 1♀ 29.IV.2012, 1♀ 6-11.IV.2012, leg. C. Holzschuh & natives (Linz and coll. Riedel).

D e s c r i p t i o n of ♀: Body length 14 mm. Flagella slightly lanceolate, with 41 flagellomeres; first flagellomeres (without anellus) length 2.8x width; 12th segment square; flagellomeres beyond the middle attenuated, the widest 1.5x as wide as long. Temples parallel behind eyes, roundly narrowed caudally. Genae with scattered punctures. Distance of lateral ocelli to the eyes c.1.1x as long as their diameter. Malar spaces c.0.5x as long as the width of mandibular bases. Hypostomal carinae not elevated.

Mesosoma with long grey hairs. Mesoscutum, mesopleura and metapleura with rather dense punctures, shining. Scutellum flat, slightly wider than long, with lateral carinae in basal 0.3, with scattered puncture. Propodeum rounded, areae basalis and superomedia confluent, area superomedia hexagonal, costulae caudal to its middle ( fig. 11 ). 1 st lateral areae of propodeum punctate and largely smooth. Hind coxae densely punctate, with weak and indistinct scopa in apical 0.2. Hind femora punctate, with scattered punctures in the ventral half, length 3.7x height. 3 rd tarsomeres of middle legs c.1.3x as long as wide.

Metasoma strongly oxypygous. Lateral fields of postpetiole about 0.5x as wide as median field, punctate; median field with coarsely punctured striae. Gastrocoeli strongly impressed, with longitudinal ridges. Thyridia oblique, c.0.8x as wide as their interval. 2 nd tergite length 0.85x width ( fig. 17 ). 2 nd and 3 rd tergites with dense punctures and fine central aciculation, matte; fourth tergite with fine superficial punctures, shining; following tergites almost smooth and strongly shining. Seen from dorsal, ovipositor sheaths c.0.65x as long as seventh tergite.

Color: Black. Ivory are palps, mandibular bases, rings on flagellomeres 8-15, clypeus except apical margin, face except triangular or rhombic black central spot, frontal orbits, wide outer orbits in the ventral 2/3, triangular vertical spots, collare, upper margins of pronotum, spots on tegulae, subtegular ridges, sides of scutellum, fore and middle coxae mainly, fore and middle trochanters and trochantelli completely, and hind trochanters partly. Legs completely reddish-yellow. Wings slightly infuscate; pterostigma blackish.

3: Body length 15 mm. Flagella with more than 40 segments (tips broken off); tyloids on flagellomeres 9-20, long-oval. Fore metatarsi without apical teeth; hind femora length 3.8x height. Area superomedia wider than long. 2 nd tergite length 1.1x width. Clypeus and face completely ivory, flagellomeres 9-17 with ivory stripes. Structure and coloration otherwise as in the ♀.

R e m a r k: The available specimens differ slightly from the type (temples slightly wider, hind coxae without yellow spots) but seem to be conspecific. For a better understanding of this species, I give a description of the Laotic material here.

D i s t r i b u t i o n: Known from Japan and Taiwan, new for Laos.
