Diagnosis. The new species has the dorsal tibial spines on external side larger and more numerous while small and less numerous on internal side, which is characteristic for N.? angustipennis Gor. 2008 but the differences in N. virens are less extreme than in the latter species. It differs however strikingly from that species by the long substraight ovipositor while it is short and curved in N.? angustipennis and by the shape of the subgenital plate being angularly rounded instead of bilobate. The shape of the ovipositor resembles that of N. amplus Gor. 2008 . It differs by the shape of the subgenital plate being almost triangular with swollen rounded tip instead of widely rounded and by the seventh sternite that is provided with a pair of distinct grooves at the baso-lateral angles.
Description. Small to medium sized species. Head: Face ovoid; forehead nearly smooth with some scattered impressed dots; fastigium verticis distinctly wider than scapus, indistinctly separated from fastigium frontis by a very shallow transverse furrow; ocelli little distinct; without subocular furrow ( Fig. 79E View FIGURE 79 ). Abdominal tergites two with small and three with distinct stridulatory pegs (7, 17;>14,>12; n = 1, on third tergite partly hidden by femur).
Wings reduced to small flaps just surpassing hind margin of metanotum ( Fig. 78D View FIGURE 78 ).
Legs: Fore coxa with a spine at fore margin; fore and mid femora unarmed; fore and mid tibiae with four pairs of large ventral spines and one pair of smaller ventral spurs; spines on fore tibia distinctly longer than on mid tibia; hind femur with 3–4 external and 5–8 internal spines on ventral margins; hind tibia with spaced spines on both dorsal margins, ventral margins with one pre-apical spine; with 3 apical spurs on both sides.
Coloration. General color uniformly light green when alive. Face light green when alive. Wings green.
Male unknown.
Female. Seventh abdominal sternite little prolonged; at anterior-lateral angles with a pit. Subgenital plate in about basal half membranous except for lateral margins; apical area triangularly rounded ( Figs. 79 View FIGURE 79 F–G). Ovipositor long, substraight; tip with margins distinctly narrowing, subacute ( Fig. 78 View FIGURE 78 C–D).
Measurements (1 female).—body: 18.5; pronotum: 3; tegmen: 1.9; hind femur: 8.5; ovipositor: female 13.5 mm.
Etymology. The new species is named for its light green color; from Latin virens (green).
