Taxonomy
Perithemis bella was first described by William Forsell Kirby in 1889.[4] In a 1930 revision of the genus by Friedrich Ris, P. austeni was synonymized to the species.[5]

Both males and females have a brown body and a thorax with a central reddish stripe.[5][4]
Males
Males have a 14 mm (0.55 in) long abdomen, a 17 by 7 mm (0.67 by 0.28 in) hind wing, and a 1.5–2 mm (0.059–0.079 in) pterostigma.[5] The face, pleura and the sides of the base of the abdomen of males are yellowish. The abdomen is broadest of all males of the genus Perithemis, and slightly fusiform. The fore wings are transparent, and deeply yellow at the base. The hind wings are completely yellow. All wings have a rust-colored pterostigma.[4][5]

Females have a 13 mm (0.51 in) long abdomen, a 17 by 6.5 mm (0.67 by 0.26 in) hind wing, and a 2.5 mm (0.098 in) pterostigma.[5] The face, pleura, and the base of the abdomen of females are dull white. The abdomen is very fusiform, the most of all Perithemis. The fore wings are transparent with a yellow antenodal space that has brown spots. The hind wings have spot in the center that may be yellow, yellow with a blackish center, or black with a yellow border. The wings have a dull brown pterostigma and blackish costa.[4][5]
