Notosemus albimaculatus ssp. laoticus nov.ssp.

H o l o t y p u s: (♀) Laos, Phongsaly prov. 2141-2´N 10206-8´E, 28.v.-20.vi.2003, Phongsaly env., ~ 1500m, Vit Kubán leg. (Linz).

P a r a t y p e s: 2♀♀ 13 with identical labels (Linz and coll. Riedel).

R e m a r k: This taxon resembles Notosemus albimaculatus s.str. SHENG & SUN in structure and main colour pattern. It differs by the reddish coloration of mesosoma and narrower malar spaces. In my opinion, these differences are not sufficient to separate two different species.

D e s c r i p t i o n

♀: Body length 6.5-7 mm. Flagella with 28 segments; 1st flagellomere length 5.8-6x width, 2nd flagellomere length 4.5-4.8x length. Head large, seen from dorsal width 1.75x length. Distance of lateral ocelli to eyes 1.75x their diamater. Temples slightly and roundly narrowed behind eyes, length 0.4x eye width. Malar spaces length 0.5-0.6x width of mandibular bases. Propodeum with smoothened sculpture in frontal third, with transverse striation in caudal 2/3; spiracles short-oval, c.1.5x longer than wide. Area superomedia hexagonal, c.1.3x wider than long, lateral carinae partly obsolete, costulae in frontal 0.2. Hind femora length 3.9x height. 6 th and 7 th tergites with large membraneous concavities at caudal margins. Ovipositor sheaths about as long as height of metasomal apex, only slightly bent upwards in two specimens, strongly bent in one specimen. Structure otherwise as described for N. albomaculatus s.str.

Colour: Usually as described for N. albimaculatus s.str, but one specimen with completely ivory orbits, one other specimen with completely ivory face. Flagellomeres 7-11 with ivory stripes. Propleura yellowish; mesopleura and mesosterna, metapleura and propodeum reddish. 1 st tergite mainly reddish, infuscate basally.

3: Body length 6 mm. Flagella with 29 segments; 1 st flagellomere length 6x width. Indistinct tyloids on flagellomeres 9-11, long-oval, on basal 0.6 of flagellomeres. 1 st tergite length 3.2x width, 2 nd tergite length 2.2x width.

Colour: Face and wide orbits completely ivory; flagellomeres 11-16 with ivory stripes.

Mesopleura behind epicnemial carina and mesosterna, metapleura and propodeum reddish; mesopleura with wide yellow stripes and blackish frontal and dorsal margins. 1 st tergite and 4 th to 7 th tergites black in basal halfs and reddish apically. Hind tarsi brownish, 3 rd and 4 th hind tarsomeres pale brownish-yellow. Coloration otherwise as in ♀. D i s t r i b u t i o n: Laos .

Notosemus albimaculatus ssp. malayensis n.ssp. H o l o t y p u s: (♀) Malaysia, Pahang Tanah Rata, ~ 1800 m, S 0448´E 10136´, E. Jendik,

03.2011 (Linz).

R e m a r k: This taxon represents another subspecies (or colour form) of N. albimaculatus SHENG & SUN.
