Differential diagnosis. Polynoncus pittinoi is similar to P. neuquen , P. gemmifer and P. haafi . This species can be distinguished from the latter two by having antennae with yellow setae ( P. gemmifer and P. haafi have black setae in antennae). Also, P. pittinoi differs from P. neuquen by having bigger elytral tubercles, with the space between tubercles on the odd-numbered costae being smaller than tubercles’ size in P. pittinoi , while this space is bigger than tubercles in P. neuquen . For details of description and differential diagnosis, see Costa-Silva and Diéguez (2020).
Geographic distribution. Polynoncus pittinoi is only known from central Argentina ( Figure 48 View Figure 48 ). No material was examined beyond the type series.
