Tetralonia is a genus of rather robust, hairy bees. In the front wings the marginal cell is rather elongate, the tipslightly bent away from the costa, and the 2nd submarginal cell is much shorter than the 1st or the 3rd. The clypeus is separated laterally from the margin of the eye, the resulting space greater than that between the lower end of the eye and the mandible. The clypeus in the females is black, in males yellow. Also, in females the basal segment of the antennal flagellum is slightly shorter than segments 2 and 3 combined, while in the males the corresponding (basal) segment is very short, no more than a fourth or fifth the length of segment 2, the flagellum being very long and slender, much longer than the thorax. The scopal hairs on the hind tibiae and basitarsi are simple. In males, terga 6 and 7 are neither angulate nor spinose laterally.
