We describe and illustrate Paphanus paloi sp. n., first generic record for Brazil, and Minanga patriciamadrigalae, first generic record for Costa Rica. We present illustrated keys for the New World genera of Sigalphinae, and the New World species of Paphanus and Minanga. Minanga patriciamadrigalae sp. n. was reared from caterpillars of Chloropteryx nordicariaDHJ01 (Geometridae).
