Key to larvae of Erythrodiplax from bromeliads

1. S8–9 with posterolateral spines; prementum with 7 long and 5–6 short setae on each side; distal margin of labial palpus with fine crenulations........................................................................... .. bromeliicola

- S8–9 without posterolateral spines; prementum with 5 long and 7 short setae on each side; distal margin of labial palpus without crenulations.................................................................................. laselva The larva of E. bromeliicola was described by Trapero-Quintana & Novelo-Gutiérrez (2012). The larva of E. castanea has not been described ( Garrison et al. 2006). Lozano et al. (2011) reviewed the described larvae of Erythrodiplax species and included E. bromeliicola within the connata group. The larva of E. laselva can be distinguished easily from E. bromeliicola by the absence of lateral spines in E. laselva , while that of E. bromeliicola has well-developed spines on S8–9 ( Trapero-Quintana & Novelo-Gutierrez 2012). E. connata is the only other known species of Erythrodiplax that lacks posterolateral spines on S8–9 ( Lozano et al. 2011).
