The new species is dedicated to Dr. Lubomir Masner, world expert on Platygastroidea ( Hymenoptera  ), who collected most of the specimens of the new species (noun in the genitive case).

Male (habitus: Fig. 105View Figs 101–106)

Differs from female mainly as follows. Body length: 1.1–1.3 mm. Body colour brown to dark brown ( Fig. 105View Figs 101–106). Vertex without any metallic reflections. Flagellum brown, basal segments usually slightly lighter ( Fig. 106View Figs 101–106). Fore wing less infumate. Legs paler, mainly yellow, mid and hind coxae light brown. Gaster with gt1 and syntergum brown, remaining tergites with basal half lighter. Fu1 length about 2.8 × width; length of pedicel plus flagellum 2.7–2.9 × as long as head width. Mesepimeral sulcus from barely visible to conspicuous. Fore wing length about 2.3× width. MV about 4.7 × as long as SV. Petiole quadrate. Gaster (inflated) length about 1.4× width, gt1 occupying less than half length of gaster.




Specimens of this species are superficially similar to those of N. merida  sp. nov., from which they can be separated by the shape of the clypeal margin, which is slightly emarginate in N. masneri  sp. nov. ( Fig. 99View Figs 96–100) and produced in N. merida  sp. nov. ( Fig. 110View Figs 107–111). Individuals of the former species are also overall more strongly sculptured, the head of females has distinct metallic reflections ( Fig. 98View Figs 96–100) and the first gastral tergite is longer.
