Xanthocampoplex huberti Rousse et Villemant , sp. nov.

( Fig. 10 )

Diagnosis. Yellow orange medium sized species, with black flagellum and ocellar triangle and sometimes a darker median stripe on mesoscutum. It is readily recognizable by its small areolet, the strongly rugose propodeum and the strong ventral flange on mandible.

Description. FEMALE (3 specimens). Fore wing length 5.6–6.2 mm.

Head. Temples moderately long, almost smooth; head strongly constricted behind eyes; occipital carina complete; ocellar triangle equilateral; OOi = 0.5, IOi = 1; frons and vertex finely granulate; face and clypeus rugose, the rugosity somewhat organized in semi-circular striations on lower face; clypeus distinctly convex in profile view, its apical margin impressed, Ci = 1.7; clypeal fovea wide, oval, its greatest diameter as long as malar space; MLMi = 0.4; mandibles stout with a strong ventral flange narrowing gradually toward apex, upper tooth barely longer than lower; antenna with 35–37 flagellomeres; FLi1 = FLi2 = 2.5.

Mesosoma. Pronotum rather smooth centrally, epomia strong medially; mesopleuron mat, deeply and densely rugose punctate, with an oblique concave and striate impression below speculum, speculum almost smooth, barely shining; metapleuron rugose with punctuation posteriorly merging into vertical wrinkles; mesoscutum coarsely shagreened punctate, with short inter-punctures finely granulate; notaulus indistinct; scuto-scutellar groove deep with high lateral flanges; scutellum convex, rugose reticulate, with lateral carinae at extreme base; propodeum coarsely rugose, the roughness hiding posterior carination; lateral transverse carina strong delimiting a small triangular area basalis; area superomedia and petiolaris forming a deep furrow striated posteriorly. Coxae 1–2 almost smooth, hind coxa shagreened punctate; hind tarsomeres 1–4 with a weak longitudinal row of densely spaced hairs; tarsal claws strongly pectinate. Fore wing with areolet minute, triangular oblique and strongly petiolate, 2Rs-m 0.5x as long as 3Rs-m; cu-a barely distad to Rs&M; hind wing with distal abscissa of Cu1 present but faint and not connected to vertical 1/Cu&cua; M+Cu medially angled.

Metasoma. Metasomal tergites almost smooth with moderately dense hairs; tergite I with glymma short but distinct; tergite II with thyridium oval and shallowly impressed, distant from anterior margin of tergite by its greatest diameter and from lateral margin by its shortest diameter; OTi = 0.3; ovipositor straight.

Color. Overall yellowish orange with head generally more yellow and ocellar triangle black, mesoscutum somewhat brownish anteriorly or with a distinct median dark stripe and a scuto-scutellar groove dark brown anteriorly; scape and pedicel orange with a narrow stripe on outer side; flagellum black brown, clearer at apex; ovipositor sheath dark brown.

MALE (2 specimens). Fore wing length 5.5–6.0mm. Same color as female. Darker specimens have metasomal tergites basally infuscate, scuto-scutellar groove and two black brown basal maculae on propodeum.

Etymology. Named for Thierry Hubert, organic farmer in La Caroline.
