Trychnopalpa is a genus of moth in the family Gelechiidae. The only member of the genus was described by Edward Meyrick in 1913, and it was separated by A. J. T. Janse in his 1958 The Moths of South Africa. Povolny gave the same member of this genus the now synonymised generic name Synthesiopalpa. The genus contains only one species, Trychnopalpa fornacaria, which is found in South Africa.
