Newly discovered or little-known interspecific hybrids in Heliconius and Eueides. a. Eueides isabella eva × E. vibilia vialis, male, hybrid no. 4; b. Eueides isabella eva × E. procula vulgiformis, male, hybrid no. 6; c. Heliconius numata aurora × H. melpomene malleti, female, hybrid no. 11; d. Heliconius hecale zeus × H. elevatus perchlorus, male, hybrid no. 16; e. Heliconius ethilla narcaea × H. besckei, female, hybrid no. 28; f. Heliconius numata superioris × H. melpomene meriana, male, hybrid no. 10; g. Heliconius melpomene cythera × H. cydno alithea, male, hybrid no. 34; h. Heliconius melpomene ssp. nov. × H. cydno hermogenes, female, hybrid no. 65; i. H. erato petiverana × H. charithonia vasquezae, male, hybrid no. 158; j. Heliconius hecalesia octavia × H. hortense, male, hybrid no. 160. For further details, see Table 1 and Additional File 1. All hybrids are putative F1 progeny of interspecies hybridization, except e which is interpreted as a backcross to H. besckei.
