Lasioglossum genaroi sp. nov. is a quite large L. (Dialictus), being similar in size to L. ferrerii. In direct comparison, size alone is often enough to distinguish L. genaroi sp. nov. at a glance from L. gundlachii, L. dispersum sp. nov. and L. enatum sp. nov. Etymology The specific epithet is a noun in the genitive case in honour of Julio Genaro for his contributions to the study of bees and other insects in the Greater Antilles.
