Intraspecific variation
Females from Brazil and Ecuador (Fig. 19) are uniformly brown on the dorsal wing surface while the female from Panama (Fig. 18) has the basal parts of both wings blue. Their genitalia, however, are uniform. This geographic variability is similar to that in Oenomaus cyanovenata.
Behavior/ biology
Territorial behavior on a hilltop in Panama (Canal Area, Gamboa, Cerro Pelado) was observed in January and August at 15:00 hours (vouchers in USNM). Two mating pairs were also collected on the same hilltop in January and March at 15:00 hours (vouchers in USNM).
Female
We illustrate adult females that were collected in copula (Figs 18–19) and the genitalia of one (Fig. 37).
COI DNA sequence
A female from Brazil, Pará (CF-LYC-064), which has a wing pattern similar to the females collected in copula, is 3.1% divergent from a male from Peru (CF-LYC-085).
