Ctenocolletes tigris is a species of bee in the family Stenotritidae. It is endemic to Australia. It was described in 1983 by Australian entomologist Terry Houston.
The specific epithet tigris (Latin: âÂÂtigerâÂÂ) alludes to the colour pattern of black and yellow integumental bands across the metasoma.
The body length of males is 16.5 mm; that of females is 16âÂÂ19 mm.
The species occurs in the Great Victoria Desert of Western Australia. The holotype was collected 36 km north-north-east of Neale Junction. Flowering plants visited by the bees include Dicrastylis, Baeckea, Wehlia, Acacia, Ptilotus, Grevillea, Newcastelia, Teucrium, Thryptomene and Solanum species.
The adults are solitary, flying mellivores, with sedentary larvae, that nest in burrows dug in soil.
