摘要：A new species of Lachesilla, from Cabrits National Park, St. John’s Parish, Dominica, is here describedand illustrated. The phallosome is V-shaped, and it is autapomorphic in having the distal ends of the apodeme armsarticulated to each clasper. Based on these characters, a new species group is created, close to the L. forcepeta andL. palmera species groups (the latter also diagnosed in this paper). The holotype is deposited in the National InsectCollection (CNIN), Instituto de Biología, Universidad Nacional Autónoma de México, Mexico City.
