Notosemus heinrichi nov.sp. ( fig. 14 , 19 , 21, 38)

H o l o t y p u s:(♀) Burma, Mt. Victoria Chinhills, 2200m, VI.38, leg. G. Heinrich (ZSM).

R e m a r k: This new species runs to couplet 7 in the key of SHENG et al. (2016), but can be separated from N. albimaculatus SHENG & SUN and N. wugongicus SHENG & SUN by the extensive yellow coloration of head and mesosoma and different structure and coloration of the metasoma.

D e s c r i p t i o n:

Body length 7.8 mm. Both antennae missing. Head large, seen from dorsal width 1.7x length. Distance of lateral ocelli to eyes 1.7x their diameter. Temples rather short, moderately and roundly narrowed behind eyes, length 0.4x eye width. Frons, vertices and temples granulate, matte. Face, clypeus and genae with very fine dense punctures. Clypeus 2.3x wider than long, slightly shining; apex rounded, rugose, without paramedian tubercles. Mandibles with two teeth, lower teeth c.0.5x as long as upper ones. Genae with very scattered punctures, shining. Genal carinae reaching mandibular bases. Mesosoma granulate, with fine punctures. Notauli slightly impressed in frontal 0.3 of mesoscutum; mesopleura with smooth specula. Epicnemial carina narrow; sternauli impressed in frontal 0.5 of mesopleura; metapleura with coxal carinae present. Scutellum moderately elevated, granulate, slightly wider than long, with lateral carinae in frontal 0.4. Propodeum with roundish spiracles. Area basalis without lateral carinae. Area superomedia heart-shaped, c.1.5x wider than long, costulae in frontal 0.3. Area petiolaris distinctly impressed, with smoothened microsculpture and obsolete lateral carinae. Hind coxae finely punctate, without scopa; hind femora finely and densely punctate, length 4.8x height; claws not pectinate. Areolets pentagonal, frontal distance of intercubiti 4x their diameter, 2 nd recurrent veins in their middle; nervuli interstitial.

1 st tergite length 2.3x width, postpetiolus moderately widened, without dorsal carinae, finely punctate. 2 nd tergite length 1.65x width; with large but indistinct, almost rounded thyridia; thyridia c.3.x wider than their interval. 2 nd to 4 th tergites granulate, with scattered fine punctures, matte; 5 th tergite with smoothened granulation; following tergites almost smooth and shining. 6 th tergite with slightly concave caudal margin; 7 th tergite strongly excised caudally. Ovipositor sheaths curved upwards

Colour: Head cream-yellow; black are mandibular teeth, frons medially, ocellar field and dorsal part of occiput. Mesosoma black; cream-yellow are propleura, pronotum except central transversal stripe, W-shaped central spot on mesoscutum, tegulae, subtegular ridges, mesopleura caudal to epicnemial carina, caudal-median spots on mesosterna, metapleura dorsal to coxal carinae and caudal 3/4 of propodeum except areae superomedia and petiolaris. Metasoma red; 1 st tergite black; postpetiolus with reddish spot apically; 2 nd and 3 rd tergite with diffuse brownish suffusion laterally. Legs red; fore and middle coxae and trochanters cream-yellow; hind coxae with yellow spot dorsally, slightly infuscate dorso-apically. Wings hyaline, pterostigmas ochreous.

D i s t r i b u t i o n: Only known from Myanmar.
