Abstract
Malipatil, M.B., 1991. Three newspecies ofGminatellus Millerfrom northern Australia
(Heteroptera: Reduviidae). Memoirs ofthe Museum ofVictoria 52: 355-359.
Three new species of Gminatellus Miller are described: 6'. elegans sp. nov. (Northern
TerritoryandQueenslandincludingtheTorresStrait Islands),G.fasciatussp.nov.(Queens-
land) and G. maeulutus sp. nov. (Queensland). A key to the species of Gminatellus is
given.
