Lepthemis hamatogastra Kirby, 1890: 39 . Incorrect spelling. Type material. Not examined. Diagnosis. Thorax, dorsum of abdomen, and dark basal spot on HW reddish brown (female and sexually immature male), or thorax and first three abdominal segments brown and abdominal segments 4–10 red (mature male). Basal area on HW does not reach the first antenodal vein or the last rows of cells to anal angle, but reaches beyond the MP crossvein, and the AA ( Fig. 4 ). Posterior extension of ventral teeth on male cercus about the same level as the apex of epiproct or less ( Fig. 13 ). Posterior lobe of the vesica spermalis is not covered by lateral lobe ( Fig. 20 ), which extends more posteriorly than the medial lobe. Hook bilobed, rectangular ( Fig. 25 ) and not perpendicular to the longitudinal axis of vesica spermalis ( Fig. 18 ). Cornua diagonal with respect to vesica spermalis transversal axis, with lobes separate to apex, and covered by lateral lobes in lateral view ( Fig. 19 ). Lab> 30mm , LcaS4/LclS4>2.1.

Erythemis haematogastra adults are common at small lakes in both conserved and disturbed environments where rest on Eleocharis Brown , Nymphaea Linnaeus , and Eichhornia crassipes (Mart.) Solms ( Ferreira and Fonseca 2003 ; Palacino-Rodríguez and Millán 2010). The period of greatest activity of E. haematogastra in rice fields has been registered from 12:00 to 16:00 hrs (Palacino-Rodríguez and Millán 2010). Distribution. From Mexico to Brazil ( Fig. 33 ), between 3–1000 m .asl.
