Muchmore Department of Biology, University of Rochester Box 27021 1, Rochester, New York 14627-0211 Abstract: A history of the family is presented. All of the genera and species previously assigned to the family are reviewed, and 4 new species are described: Leucohya parva from Venezuela and Guyana, Mexobisiunz venii from Belize and Guatemala, M. dorninicanu~nfrom the Dominican Republic, and Paravachoniuln sprousei from Mexico. Two sub- families are established: Bochicinae (including the genera Alatillobisium, Bochica, Troglobochica, Troglohya, and Vacholziu~n)and Leucohyinae (including Apohya, Leucohya, Mexobisiurn, and Paravachoniurn).
