Polistes (Epicnemius) occultus n. sp., a neotropical social wasp, is d
escribed. Structural and colour similarity relations with other specie
s of P. (Epicnemius) are discussed. A principal component analysis per
formed on the covariance matrix of ten continuous morphometric charact
ers, sampled in P. occultus and two related species, provides addition
al support on the specific status of P. occultus.
