Key to the males of Domene (Lathromene) View in CoL species

Based on the key to the Iberian Lathromene species (males) by Serrano et al. (2015) (omitting D. hispanica whose male is unknown), we present an updated key including the four species described by Struyve (2018) and Magrini & Carotti (2019) and the two new species:
