Lophocampa desotoi is named in honor of Carlos De Soto Molinari, naturalist photographer, in recognition of his contribution to the knowledge of Dominican heterocera. Distribution. Lophocampa desotoi n. sp. is known from the vicinity of the city of Constanza between 900 and 1808 m of altitude, in very humid forest environments. Surveys carried out around this municipality have led to the discovery of several very distinctive genera with a very limited distribution, such as Caribarctia Ferguson, 1985 and Westindia Vincent, 2014 (Lepidoptera, Arctiinae).
