Picramnia thomasii, a new species from the state of Guerrero, Mexico is described and illustrated. It is related to P. guerrerensis, but differs by having leaflets with indumentum on the underside, a larger staminate inflorescence with more glomeruli, petals with a different shape and color, longer stamens, fruits with indument, smaller seeds, and the current known distribution restricted to the low dry semi-deciduous forest of Acahuizotla.
