The present paper is based upon a small collection of water striders of the family Hebridae, collected by the junior author while conducting a field survey of the Hemiptera of Curaçao and the other Netherlands Antillean islands in the Caribbean Sea. It is striking that the hebrids mentioned here were found only on the three islands of the Leeward Group, off the coast of Venezuela, i.e. Aruba, Curaçao and Bonaire. On the very small islands of St. Martin, St. Eustatius and Saba, situated about 900 km farther to the northeast, not a single hebrid has been met with, in spite of the fact that suitable habitats were examined very carefully for their occurrence. The collection comprises four species of hebrids, divided between two genera: Merragata hebroides, from Aruba, Curaçao, and Bonaire; Hebrus concinnus, from Curaçao; Hebrus consolidus, from Curaçao; Hebrus elimatus, nov., from Aruba, Curaçao, and Bonaire.
