 Diagnosis and remarks. Remarkable and common species, males of H. erythrogastrum (as the name implies) possess a vibrant red abdomen, an almost unique feature within Heteragrion (H. albifrons comes close) that distinguishes this species from the other species of both groups. Additionally, the following character combination separates it from the remainder of Group B species: ridge above ML consisting of two rows of small teeth, the lower very weak (Figs. 32c–d).
