How do homopteran forewings differ from the forewings of heteropterans?

The names Heteroptera and Homoptera are derived from the distinct structural differences in their wings.1

In heteropterans, the forewings (often called hemelytra) are divided into two distinct sections: a thickened, leathery basal half and a membranous apical half with visible veins. When at rest, these wings are held flat over the abdomen, with the membranous tips overlapping to protect the delicate hindwings beneath.123

In contrast, the forewings of homopterans possess a uniform texture throughout their entire length, appearing either entirely membranous or slightly thickened. Unlike the flat resting position of heteropterans, homopteran forewings are held in a rooflike position over the abdomen when at rest, overlapping only slightly at the inner apical margin.143
