Nezara antennata var. balteata Horváth, 1889: 32 (syn. by Wu, 1933)

Nezara viridula ; Takahashi, 1948: 107 –108 (non Linnaeus, 1758) (misidentification, see Ishihara 1950; Rider, 2006: 329)

Diagnosis. Head: apical third of antennal segment III and apical half of IV black. This character is excluive of N. antennata ; other species may have these antennal segments darkened but never black. Thorax: ostiolar ruga auriculate, conspicuous. Abdomen: connexival sutures with black or darkened maculae at middle, character absent in N. viridula and N. yunnana . Male: ventral rim of pygophore with brims restricted to posterolateral angles, abruptly ending ( Fig. 8B ), shared with N. viridula , N. yunnana and N. similis ; paramere bilobate, inferior lobe thin ( Fig. 8B ), character exclusive of this species; median bristles on paramere attached at apex of a short digitiform process directed to lateral surface ( Fig. 10 E–F ; 12F–H ), shared with N. viridula and N. yunnana . Female: posterior margins of gonocoxites 8 sinuous near sutural angles; basal half of laterotergites 9 concave; digitiform processes of capsula seminalis distinct in length, one surpassing anterior annular flange ( Fig. 17 B ), this character distinguishes N. antennata from N. viridula and N. yunnana .
