dc.description.abstract Background: Sister species divergence and reproductive isolation commonly results from ecological adaptation. In mimetic Heliconius butterflies, shifts in colour pattern contribute to pre- and post-mating reproductive isolation and are commonly correlated with speciation. Closely related mimetic species are therefore not expected, as they should lack several important sources of reproductive isolation. Results: Here we present phenotypic, behavioral and genetic evidence for the coexistence of two sympatric &#39;cryptic&#39; species near Florencia in the eastern Andes of Colombia that share the same orange rayed colour pattern. These represent H. melpomene malleti and a novel taxon in the H. cydno group, here designated as novel race of Heliconius timareta, Heliconius timareta florencia. No-choice mating experiments show that these sympatric forms have strong assortative mating (approximate to 96%) despite great similarity in colour pattern, implying enhanced divergence in pheromonal signals. Conclusion: We hypothesize that these species might have resulted from recent convergence in colour pattern, perhaps facilitated by hybrid introgression of wing pattern genes. en
