4. Subgenus - Dieunomia vs Epinomia

10Dieunomia - The first segment of the labial palp is greater than or equal to the subsequent segments 2-4 in terms of length - In males, the terminal antennal segment is flattened and broadened such that it is much wider in the apical half than in the basal half - In females, the hair of the scutum is entirely short and usually semi-appressed overall, giving it a more dense, crewcut appearance AND the pit interspaces in the posterior half of the scutum rarely, if ever, approach one pit diameter - In general, Dieunomia is much larger than Epinomia although D. bolliana of Dieunomia is about the size of D. triangulifera of Epinomia    8Epinomia - The first segment of the labial palp is shorter than the subsequent segments 2-4 in terms of length - In males, the terminal antennal segment is relatively unmodified and of about equal width throughout such that it appears somewhat like a fingertip - In females, there are much longer, more erect hairs present on the scutum or if with short hairs then the pit interspaces in the posterior half of the scutum almost always exceed one pit diameter at least in part - In general, Dieunomia is much larger than Epinomia although D. bolliana of Dieunomia is about the size of D. triangulifera of Epinomia
