Ctenocalus maculipennis rufopetiolatus nov.ssp. ( fig 22 )

M a t e r i a l e x a m i n e d: Holotypus:(♀) Gabon - prov. Ogooué-Ivindo, Parc National de ĺ Ivindo , station de Ipassa , 0°30́45́́N 12°48́10́́ E, 20/29.II. 2012, leg. M. Pavesi ( MSNM, Milan ).

R e m a r k: The new subspecies resembles C. maculipennis maculipennis (MORLEY) by its structure and main color pattern. The subspecies from Gabon is slightly larger than the specimens described from Uganda and differs by its red petiolus and the brownish 7 th tergite without an ivory apical band.

D e s c r i p t i o n: ♀: Body length 13 mm. Flagellum with 41 flagellomeres, slightly lanceolate; 1 st flagellomere 5.2x longer than wide; 2 nd flagellomere 3.5x longer than wide, widest flagellomeres beyond the middle about square. Temple wide, parallel behind eye, about as wide as eye. Temple finely granulate, with coarse but very scattered punctures. Occiput deeply emarginate. Distance of lateral ocellus from eye c.1.2x its diameter. Face and clypeus coarsely and densely punctate. Clypeus c.1.7x wider than long, flat and thin apically. Lower mandibular tooth small and turned inwards, mandible seen from frontal almost sickle-shaped. Malar space c.1.1x wider than the mandibular base. Genal carina reaching the mandibular base.

Collare with strong transversal rim, epomia present. Mesoscutum finely granulate, with scattered coarse punctures, mainly along the (indistinct) notauli. Mesopleuron and metapleuron densely and coarsely rugose-punctate, speculum coriaceous. Juxtacoxal carina not developed. Scutellum moderately elevated, wider than long, with coarse scattered punctures and complete lateral carina. Propodeum granulate, matte, with weak lateral carina of the area petiolaris only, other carinae not developed. Hind coxa granulate and punctate, with weak scopa in apical 0.2. Hind femur densely punctate, 4.4x longer than wide. All claws strongly pectinate.

Areolet quadrangular, 2 nd recurrent vein slightly distal to its middle, nervulus postfurcal by 2x its width.

Metasoma oxypygous. Postpetiolus moderately widened, granulate and with very scattered punctures, median field not separated. Gastrocoelus transversely triangular, with some fine longitudinal ridges. Thyridium very large, oblique, 2.5x wider than the interval. 2 nd tergite 1.3x wider than long, 3 rd tergite 1.6x wider than long; both tergites granulate and coarsely and densely rugose-punctate; 4 th tergite with less dense superficial punctures. Ovipositor sheath slightly reaching beyond metasomal apex.

Color: Black. Ivory are stripes on flagellomeres 7-14 and 3 rd- 4 th hind tarsomeres. Pale reddish are all coxae and trochanters and the petiolus. Postpetiolus and following tergites black with slightly bluish shine, 6 th and 7 th tergites brownish. Wings hyaline, pterostigma brown; fore wing with a wide brown band behind pterostigma, fore and hind wings with brownish apical spots.
