4B418A8BDCF85ED681279C5EEF359F5A.taxon	diagnosis	Diagnosis. This species is closely similar to N. yasumatsui taiwana Tsuneki, 1982 in having frons with coarsely, irregular reticulate ridges; basal half of mesoscutum coarsely, densely, irregularly rugose; posterior half of mesoscutum with abundant long longitudinal wrinkles. It differs by the following characteristics (characters of N. yasumatsui taiwana in parentheses): propodeal dorsum with straight, longitudinal ridges from base to apex, interconnected by conspicuous, short, transverse carinae forming reticulate pattern (propodeal dorsal surface with curved oblique ridges without conspicuous short transverse carinae, not reticulate); submarginal cell length approximately equal to discal cell (discal cell longer than submarginal cell); mesoscutellum with conspicuous longitudinal carinae (mesoscutellum without longitudinal carina).	en	Li, Chengfang, Li, Qiang, Ma, Li (2025): Six new species of the genus Nitela Latreille (Hymenoptera, Crabronidae) from China, with a key to the Oriental species.
