Notosemus polyambonios KUSIGEMATI, 1986

M a t e r i a l: Myanmar, Mt. Victoria Chinhills, 2400-2800 m, 1♀ v.1938, leg. G. Heinrich (ZSM).

R e m a r k: The specimen from Myanmar is smaller than the holotypus from Taiwan (7 mm instead of 11.4 mm). Its flagellum has 32 segments ; 1 st flagellomere length 5.6x width. Hind femora length 4.2x height. It is otherwise typical in structure and coloration.

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

P a r a t y p e s:(2♀♀) Burma, Mt. Victoria Chinhills, 2200m, VI.38 leg. G. Heinrich (ZSM).

R e m a r k: This new species differs from the described ones by its extensive reddish coloration. It runs to N. rufomaculatus (CAMERON) in the key of SHENG et al. (2016), but can be differentiated by the mainly reddish color of head, cream-yellow palps and completely red hind tibiae.

Scutellum slightly wider than long, slightly elevated, granulated, with lateral carinae in basal 0.7. Propodeum completely carinate; spiracles short-oval, c.1.5x longer than wide. Area superomedia hexagonal, c.1.2x wider than long, costulae in frontal 0.4. Area petiolaris with fine transverse striation. Dentiparal edges with elevated carinae, but without distinct apophyses. Hind coxae punctate, without scopa; hind femora punctate, length 4.3x height; claws not pectinate. Areolets pentagonal, frontal distance of intercubiti 3x their diameter, 2 nd recurrent veins slightly proximal to their middle; nervuli interstitial.

1 st tergite length 2.6x width. Postpetiolus moderately widened, without dorsal carinae, finely granulate and shining. 2 nd tergite length 1.6x width; with large, almost rounded thyridia; thyridia c.2x wider than their interval. 2 nd and 3 rd tergites granulate, matte; 4 th tergite finely granulate basally, mainly smooth and shining; 5 th tergite smooth and strongly shining, with very scattered punctures. 6 th and 7 th tergites with strongly concave and membraneous hind margins. Ovipositor sheaths about as long as height of metasomal apex, moderately bent upwards.

Colour: Reddish. Flagella black. Cream-yellow are stripes on flagellomeres 9-14, palps, bases of mandibles, clypeus, face, genae, wide orbits (interrupted on temples), frontal and upper margins of pronotum, subtegular ridges and tegulae, mesopleura behind epicnemial carina (except central reddish spot), scutellum and postscutellum, carinal triangles, large spot on metapleura, areae posteroexternae, fore and middle coxae and trochanters and trochantelli, hind trochanters, dorsal spot on hind coxae, and 2 nd to 5 th hind tarsomeres. Black are median frons above antennae, ocellar field, propleura, mesopleura frontal to epicnemial carina, prescutellar groove, and narrow margins of propodeum. Metasoma reddish; 1 st tergite basally and 2 nd to 6 th tergites centrally more or less blackish. Wings hyaline, pterostigmas yellow.

The paratypes from Myanmar have a slightly different colour pattern: face with central reddish stripe, area petiolaris black, apical hind tarsomeres reddish-brown, and mesopleura with central blackish spots.
