[lugens: from the Latin lugeo, "mourning, grieving, lamenting," and referring to a dark or dusky coloration or pattern. Lugens is a relatively common specific name and has been used not only in plants, but also in animals, birds and insects, among which are the caterpillar Uraba lugens, the damselfly Argia lugens, the beetle Agonum lugens, the butterfly Agrias lugens, the widow monkey Callithrix lugens, and birds called the mourning wheatear Oenanthe lugens and the dusky turtle dove Steptopilia lugens. The name must refer to the dark stripe on the petals.]
