Remarks and differential diagnosis. What lead us to believe that our material represented a new species was that, before comparing our specimens to the lectotype housed in Belgium, we first compared them to specimens identified as L. andromache from Frederico Lencioni’s Collection in Jacareí, São Paulo State, collected in Bahia. In that comparison, we found that those specimens had significant differences in cercus, hind lobe of prothorax and shape of pterostigma, therefore they are described here as L. jeromei . In regard to overall morphology, the closest species to L. jeromei is L. andromache . Despite their resemblance, there are many structures in L. jeromei that allow us to differentiate these two species ( L. andromache in brackets): in dorsal view hind lobe of prothorax ( Fig. 2d View FIGURE 2 ) nearly straight at the middle (with a slight cleft, Fig. 2c View FIGURE 2 ), with blunt rounded corners ( Figs. 2b, 2d View FIGURE 2 ) (with thin lateral projections, Figs. 2a, 2c View FIGURE 2 ); pterostigma rhomboid ( Fig. 1d View FIGURE 1 , below) (quadrilateral, Fig. 1d View FIGURE 1 , above); cercus in lateral view ( Fig. 3c View FIGURE 3 ) with a small, blunt, medial projection (with a more pronounced medial projection, Fig. 3a View FIGURE 3 ); cercus in dorsal view ( Fig. 3d View FIGURE 3 ) distal tooth not reaching middle of cercus, blunt tips (distal tooth longer, reaching middle of cercus, acute tip, Fig. 3b View FIGURE 3 ). Apart from the morphology, coloration has also shown to be different among the two species, such as the postocular region with a transversal pale stripe (such stripe absent), and some paler areas in L. jeromei . However, due to the paucity of individuals of L. jeromei , we could not make further statements on coloration according to aging.

Habitat and ecology. Leptagrion jeromei was always collected associated with epiphyte bromeliads which indicates that, as the other congeners, this new species also breeds in phytotelmata.
