Comments.

This species is similar to P. (Polynema) gracile; both have scape smooth, clava with six mps, and mesoscutum smooth. However, this species is distinguished from P. gracile by the pronotum with four setae on each side along the anterior margin; forewing with discal cilia being relatively sparser and with the longest marginal seta as long as width of wing. In P. gracile, the pronotum has seven setae on each side along the anterior margin; the forewing has very long and irregularly distributed discal setae, and the longest marginal setae are shorter than the maximum width of the wing.
