Kosmimodes howdenae Setliff, new genus and new species, is described for a brilliant metallic green broad-nosed weevil from the dry forests of Pedernales Province in the Dominican Republic. Kosmimodes is closely related to Apotomoderes Dejean and Melathra Franz in the tribe Geonemini and distinguished from these genera by the form of the constriction on the head behind the eyes, shape of the nasal plate and median sulcus on the rostrum, and the lack of a tooth on the profemora. Images of the habitus and male genitalia and a diagnosis accompany the description. The new species is named in honor of the late Anne Howden (1927–2016) in recognition of her considerable contribution to our knowledge of Neotropical Entiminae.
