Diagnosis

Body length 14.5 mm. Head mostly reddish-brown with frons, vertex and occiput black; mesosoma black with isolated reddish-brown markings; metasoma and legs reddish brown but hind coxa partly black; wings hyaline; antenna with 33 flagellomeres; lower gena not produced laterally; clypeus transverse and with the apical margin slightly truncate in the middle; lower frons smooth and short, separated from coarsely rugose upper frons by a transverse M-shaped carina; mesosoma densely to sparsely punctate; metasoma densely punctate on tergites 1–4, sparsely punctate on the remaining tergites.

Etymology

The species is dedicated by the first author (DDP) to his friend, Luca Filipazzi (Milano, Italy) and to his courageous battle, always with a smile on his face, against Duchenne muscular dystrophy. As a modest thanksgiving for all these years of friendship and inspiration, his name is now set among Nature’s wonders, as a little piece of eternity.

Material examined

Holotype

GUINEA: ♀, “N’Zérékoré [Nzérékoré] / Fr. Guinea / 24/4 1950 / Sv. Herold Olsen ” ( NHMD). The holotype is in good condition with left wings detached and glued on a label pinned below the specimen, but the apical flagellomeres of the right antenna are missing.

Description

Female

HEAD. Mandible rather stout, punctate and setose, slightly concave on outer aspect, teeth blunt with upper tooth about 2.0 × lower tooth; malar space 0.2 × mandible basal width; occipital carina meeting hypostomal carina distant from mandible base by 0.8 × basal width of mandible; hypostomal carina raised, lamelliform; clypeus 3.2 × as wide as medially high, flat, differentiated from face by suture, punctate with apical margin smoother and slightly truncate in middle; face 4.6 × wider than high, matt and densely punctate, with a mid-longitudinal, horn-like, projecting lamella; lower frons smooth and short, separated from upper frons by a transverse M-shaped carina; upper frons and stemmaticum with a differentiated coarsely rugose surface; vertex very faintly coriaceous with inconspicuous dense punctures near occipital carina; temple about as wide as eye, roundly narrowed behind eyes; occipital carina sharp, ventrally lamellate; ocellar triangle wider than long, ocelli rather small, POL 1.1, OOL 1.4; antenna stout, widened medially, thinner apically, with 33 flagellomeres, first flagellomere 1.8 × as long.

as apically wide, second 1.3 × as long as wide, then widening towards middle with 8 th flagellomere 1.0 × as long as wide.

MESOSOMA. Pronotum striate on ventral margin, sparsely punctate centrally, otherwise finely and densely punctate; pronotal collar punctate to puncto-striate, epomia strong; mesopleuron densely punctate, punctures finer on epicnemium and subtegular ridge, speculum smooth and shining, mesopleural groove smooth above speculum, epicnemial carina nearly reaching pronotal margin below expanded subtegular ridge, dorsally fading into punctures; metapleuron densely punctate to nearly smooth ventrally; mesoscutum evenly rounded, finely and densely punctate laterally, sparsely punctate centrally, notaulus distinct to anterior third, scuto-scutellar groove quite smooth; scutellum finely and more sparsely punctate, without lateral carina, quite flat in profile; propodeum typical of genus, gently and evenly rounded in profile with median areas fused, carination distinct but weak, densely punctate with punctation obsolescent in mid-basal area.

LEGS. Fore and mid tibiae with short and rather dense bristles along anterior faces, bristle sockets large and cupular.

WINGS. Areolet closed and rhomboidal.

METASOMA. Tergite 1 densely punctate, rather short and strongly widened from base to spiracle, lateral and submedian dorsal carinae strong; tergites 2–4 punctate and coriaceous, posteriorly shining, with traces of striation basally, gastrocoelus deep, thyridia separated by 2.1 × their own width; following tergites finely and sparsely punctate, tergites 6–7 with strong setae; ovipositor sheath slightly protruding beyond metasomal apex.

COLOUR. Antennae black with a whitish median ring; head mostly reddish-brown with frons, vertex and occiput black; mesosoma black with reddish-brown markings on: dorsal and ventral margins of pronotum, subtegular ridge, centre of mesoscutum, mid-longitudinal band on mesopleuron, scutellum, postero-ventral part of metapleuron, centre of metanotum and posterior corners of propodeum; metasoma uniformly reddish-brown, petiole dorsally darker; legs reddish-brown but hind coxa largely black marked; wings barely infumate, venation testaceous to black.

Male

Unknown.

Host

Unknown.

Distribution

Guinea.
