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 ( ZSM, Munich ). Paratypes: 3♀♀ and 2♂♂ with same labels ( ZSM, Munich and MSNM, Milan ).GoogleMaps 

R e m a r k: The correlation of both sexes is questionable. The reddish color on meso-

soma, petioles, and legs are more extended in the females than in the males.

D e s c r i p t i o n: ♀: Body length 12-13 mm. Flagellum long, moderately lanceolate, with 39-41 flagellomeres, 1 st flagellomere c.2.6x longer than wide, 2 nd flagellomere 2.4x longer than wide; widest flagellomeres c.1.7-1.8x wider than long. Temple long, almost parallel or slightly narrowed behind eye, c.0.65x as wide as the eye. Distance of lateral ocellus to eye 1.3x its diameter. Temple and frons smooth and shining. Face and clypeus densely punctuate; gena with scattered punctures ventrally. Mandible large and wide, with a wide gap between both teeth, lower tooth slightly shorter than the upper one. Malar space about as long as the width of mandibular base. Genal carina reaching mandibular base.

Pronotum with oblique striae caudally and ventrally, epomia present. Mesoscutum without distinct notaulus, with coarse irregular rugae and three smooth stripes medially and in the centers of lateral fields. Mesopleuron striate dorsally and rugose ventrally, speculum smooth. Metapleuron rugose-punctate, juxtacoxal carina more or less distinct. Scutellum flat, about as long as wide, punctate and apically striate, with complete lateral carina. Propodeum coarsely rugose-punctate; area superomedia almost rectangular, longer than wide, apical carina often obsolete, finely aciculate as the area superoexterna. Area petiolaris moderately impressed, with weak lateral carina, rugose-punctate. Hind coxa punctate, without apical ridge or tooth; hind femur punctate, c.3.5x longer than

wide. Claws not pectinate. Areolet almost quadrangular, frontal distance of intercubiti 1x their width, 2nd recurrent

vein in its middle; nervulus interstitial or slightly postfurcal. Nervellus of hind wing reclivous, intercepted in its apical 0.75.

Metasoma semi-amblypygous, short-oval. Postpetiolus moderately widened apically, without dorsal carina, finely aciculate. Gastrocoelus triangular, with fine ridges. Thyridium wide, oblique, c.1.1-1.2x as wide as the interval. 2 nd tergite 1.05x wider than long, 3 rd tergite 1.55x wider than long, both tergites completey and coarsely aciculate; following tergites smooth and with fine scattered punctures, strongly shining. Ovipositor sheath not surpassing the metasomal apex.

Color: Head black. Yellowish areas are located as follows: mandible except teeth, side of clypeus, spot on gena, dorsal facial orbit and frontal orbit up to lateral ocellus (widened dorsally). Flagellum black, with ivory stripes on flagellomeres 7-13. Mesosoma mainly yellow-red. Black with metallic green shine are pronotum medially, propleurum basally, mesoscutum except narrow margins, 1 st lateral field of propodeum and sometimes area superomedia. Metasoma blackish with metallic green shine, 4 th to 7 th tergites with reddish-brown copper-like shine; 6 th and 7 th tergites with ivory apical bands. Petiolus completely and sometimes narrow margins of basal tergites yellow-red. Legs yellow-red; fore and middle tibiae caudally and fore and middle tarsi completely brownish. Hind legs except red coxa and trochanters black. Wings slightly infuscate, but without dark spots or

bands; pterostigma blackish. ♂: Body length 11 mm. Flagellum long, bristle-shaped, with 37 flagellomeres, 1st flagel-

lomere c.3.1x longer than wide. Flagellomeres without tyloids, central flagellomeres with transveral and central rings of small black hairs. Temple long, almost parallel or slightly narrowed behind eye, c.0.65x as wide as the eye. Distance of lateral ocellus to eye 1.5x its diameter. Temple and frons smooth and shining, with few fine punctures. Face and clypeus densely punctate, gena with scattered punctures ventrally. Mandible large and wide, with a wide gap between both teeth, lower tooth slightly shorter than the upper one. Malar space about as wide as the mandibular base. Genal carina reaching mandibular base.

Pronotum with oblique striae caudally and ventrally, epomia present. Mesoscutum without distinct notaulus, with coarse irregular rugae and three smoothened stripes medially and in the centers of lateral fields. Mesopleuron striate dorsally and rugose or rugosestriate ventrally, speculum smooth. Metapleuron rugose-punctate, juxtacoxal carina more or less distinct. Scutellum roundly and distinctly elevated, about as long as wide, punctate and apically striate, with complete lateral carina; area superomedia almost rectangular, longer than wide or as long as wide, apical carina often obsolete, finely aciculate or smooth. Area superoexterna finely striate. Hind coxa coarsely and densely punctate, without apical ridge or tooth; hind femur densely punctate, c.4.4x longer than wide.

Claws not pectinate. Areolet quadrangular; 2nd recurrent vein in its middle; nervulus slightly postfurcal.

Nervellus of hind wing reclivous, intercepted in its apical 0.75.

Metasoma short-oval. Postpetiolus moderately widened apically, without dorsal carina, finely aciculate. Gastrocoelus triangular, with fine ridges. Thyridium oblique, c.1.2x wider than the interval. 2 nd tergite 1.2x wider than long, 3 rd tergite 1.5x wider than long, both tergites completey and coarsely aciculate; following tergites smooth and with fine scattered punctures, strongly shining. Ovipositor sheath not surpassing the metasomal apex.

Color: Head black. Yellowish areas are located as follow: mandible except teeth, side of clypeus, sometimes spot on gena, wide facial and frontal orbits up to anterior ocellus. Flagellum black. Mesosoma mainly black with metallic blue shine; mesopleuron and hind margin of pronotum red. Metasoma blackish with metallic blue shine, 4 th to 7 th tergites with reddish-brown copper-like shine; 7 th tergite with wide ivory apical band; petiolus reddish basally. Fore and middle coxae mainly yellow; fore and middle legs otherwise red, tarsi more brownish; hind leg black, hind coxa with blueish shine, hind trochanter and trochantellus reddish. Wings slightly infuscate, without apical darkening; pterostigma black.
