The genus Enallagma ( 49 species)
Enallagma:
Charpentier 1840
Diagnosis:
Medium sized, males usually robust, male abdominal segments 3–6 usually largely blue dorsally. Pale thoracic colour blue in males, pale blue, greenish or tan in females, black humeral stripe never divided longitudinally, not reduced to hairline. Pterostigmata pale tan to nearly black, vein Ac almost always basal to midway between antenodal crossveins. Abdominal segment 10 of male without posterodorsal protuberance but often with rounded distal scale on each side of midline. Male paraprocts not bifid in lateral view; cerci with a superior arm ending in (or sometimes reduced to) a glabrous hook whose sharp edge is somewhat elongated, distinct inferior arm bearing scalariform cuticle, this arm sometimes partly fused with superior arm when latter is reduced, so scalariform cuticle overlaps the latter. Penis usually with crescentic distolateral lobes (quadrate in E. durum and E. eiseni), distinct lateral lobes present, spines or projections not present just proximal to distal flexure. Male mesostigmal plates without posteromedial lappets; female plates variable but usually without anteromedial trough and flange, posterior margin of pronotum usually smoothly rounded (sinuate in E. eiseni) and without median tubercle, middle lobe of pronotum sometimes with well defined pits. Ovipositor valves short. (May 2002 revising genus)
