Campoplex techer Rousse et Villemant , sp. nov.

( Figs 9 a–b)

Diagnosis. Black species with yellowish legs, characterized by its flagellum basally yellowish, its long malar space and its straight ovipositor.

Description. FEMALE (4 specimens). Fore wing length 2.2–2.6 mm.

Head. Temples rounded, head moderately constricted behind eyes; OOi = 0.8, IOi = 1; occipital carina complete distant from posterior ocelli by 2.5x OOi; vertex and frons finely granulate; inner margin of eye hardly concave in front of torulus; face and clypeus granulate and sparsely punctate; face transverse, 1.4x wider than high, slightly protruding medially; anterior tentorial pit deep; clypeus moderately convex, its apical margin rounded, not impressed, Ci = 1.7; mandible moderately slender, with a ventral flange on proximal 0.4, upper tooth about 1.5 times longer than lower; MLMi = 1.3; genal carina joining hypostomal carina above base of mandible. Antenna with 26–28 flagellomeres.

Mesosoma. Pronotum longitudinally strigose, without epomia; meso- and metapleuron strongly granulate and densely punctate anteriorly, the punctures merging into striations below subalar prominence, speculum smooth; mesoscutum densely granulate with sparse punctuation and short raised hair, notaulus hardly distinct anteriorly; scuto-scutellar groove deep; scutellum convex; propodeum shining, anteriorly granulate and sligthly coriaceous laterally, rather strongly carinate, areae superomedia and petiolaris confluent, the resulting area slightly concave and smoother than the rest of the propodeum, carination otherwise complete. Tarsal claws basally pectinate. Fore wing with areolet minute and strongly petiolate, 3Rs-m partly spectral, 2Rs-m 1.5x longer than distance between 2Rs-m and 2m-Cu; cu-a slightly distad to Rs&M; hind wing with 1/Cu&cu-a almost straight, Cu1 absent.

Metasoma. Tergite I slender, its basal section oval depressed with basal separation of tergite and sternite a little below mid-height; second tergite about 2x as long as apically wide and 0.8x the length of petiole; tergites alutaceous with rare punctures and hairs; ovipositor straight, apically notched, OTi = 0.7.

Color. Overall black with last tergites more brownish and legs yellowish orange; scape, pedicel and first flagellomere yellow orange, rest of the flagellum regularly darkening toward apex.

MALE. Unknown.

Comments. By its general morphology, this species can be related to the worldwide genus Campoplex and the Australian genus Neolophron Gauld, 1984 . It differs from these two genera by its malar space distinctly longer than basal width of mandible, from Campoplex by its straight ovipositor and from Neolophron by its much slender tergite I whose sternite distinctly overpass middle of tergite. Campoplex is a very specious genus that includes a considerable range of morphological diversity. Pending a revision of Campoplex and a clear definition of its limits, we do not describe a new genus for this species.
